Like hydrogen fluoride, it attacks glass and stoneware. The AI of fluoride from all sources (including non-dietary sources) is 0.05 mg/kg body weight per day for both children and adults, including pregnant and lactating women. FLUOROSILICIC ACID Transport hazard class(es) DOT Class 8 Corrosive substances. We have warehouse and office in DUBAI,can accept small order quantity from final users. [41], Although fluoride was once considered an essential nutrient, the U.S. National Research Council has since removed this designation due to the lack of studies showing it is essential for human growth, though still considering fluoride a "beneficial element" due to its positive impact on oral health. [100] Fluoridation was introduced into Brazil in 1953, was regulated by federal law starting in 1974, and by 2004 was used by 71% of the population. These fluorosilicic acid solutions are also used industrially. [2][4] Defluoridation is needed when the naturally occurring fluoride level exceeds recommended limits. Fluosilicic acid purum, 33.5-35% Synonym: Fluorosilicic acid, Hexafluorosilicic acid, Hydrogen hexafluorosilicate CAS Number 16961-83-4. [6] In 2011 the World Health Organization stated that 1.5 mg/L should be an absolute upper bound and that 0.5 mg/L may be an appropriate lower limit. Verified Supplier. About 40 million worldwide received water that was naturally fluoridated to recommended levels. [5] As a by-product, approximately 50 kg of (H3O)2SiF6 is produced per tonne of HF owing to reactions involving silica-containing mineral impurities. [78] Other agents to prevent tooth decay include antibacterials such as chlorhexidine and sugar substitutes such as xylitol. Universal salt fluoridation is also practiced in Colombia and the Swiss Canton of Vaud; in Germany fluoridated salt is widely used in households but unfluoridated salt is also available, giving consumers a choice. T. C1.

E2. Sci. Call a POISON CENTER or doctor. Fluorosilicic acid. 1778. Aluminium Fluoride from fluorosilicic acid / (AlF3 high density) Aluminium fluoride is manufactured from anhydrous hydrofluori c acid generated either from fluorspar or fluosilicic acid. This product is tested on varied parameters by our qualified quality controllers to dispatch an optimum NACRES NA.21 [27] Once a cavity occurs, the tooth's fate is that of repeated restorations, with estimates for the median life of an amalgam tooth filling ranging from 9 to 14 years. Fluorosilicic Acid Compatibility with PVC Nalsoft (Mechanical) (OP) 19 Mar 20 05:03. Consistent evidence also suggests that it causes dental fluorosis, most of which is mild and not usually of aesthetic concern. Inhalation of the vapors may cause lung edema. Decomposes when heated, with possible emanation of toxic hydrofluoric acid vapours. In addition to this, the offered fluorosilicic acid is widely used as fluoridation agents for drinking water. Here, aesthetic concern is a term used in a standardized scale based on what adolescents would find unacceptable, as measured by a 1996 study of British 14-year-olds. This Fluosilicic Acid is extensively used as fluoridation agents for drinking water. II. Performance Products. [18] In other locations, fluoridation was used and then discontinued: in Kuopio, Finland, fluoridation was used for decades but was discontinued because the school dental service provided significant fluoride programs and the cavity risk was low, and in Basel, Switzerland, it was replaced with fluoridated salt. Therefore, the purity of fluorosilicic acid used for water fluoridation should be required and monitored by public administrations to avoid long-term public health problems. [48], Existing evidence suggests that water fluoridation reduces tooth decay. [42] The European Food Safety Authority's Panel on Dietetic Products, Nutrition and Allergies (NDA) considers fluoride not to be an essential nutrient, yet, due to the beneficial effects of dietary fluoride on prevention of dental caries they have defined an Adequate Intake (AI) value for it. The increasing use of fluorosilicic acid in fluoridation of drinking water is a major factor contributing to the growth of the fluorosilicic acid market. 58 / Monday, March 26, 2012 / Rules and Regulations 08/21/2017 EN (English) Page 1 SECTION 1: Identification 1.1. The conversion to aluminium trifluoride is described as: [6] A 2007 Australian systematic review recommended a range from 0.6 to 1.1 mg/L. [50] A 2011 European Commission systematic review based its efficacy on York's review conclusion. [32], Fluoridation has little effect on risk of bone fracture (broken bones); it may result in slightly lower fracture risk than either excessively high levels of fluoridation or no fluoridation. [72] A rough estimate is that an adult in a temperate climate consumes 0.6 mg/day of fluoride without fluoridation, and 2 mg/day with fluoridation. Mineral Data Publishing, Tucson. Handling, Storage, and Precautions: fluorosilicic acid is toxic and very corrosive. [73], Fluoride toothpaste is the most widely used and rigorously evaluated fluoride treatment. [34], In the first half of the 19th century, investigators established that fluoride occurs with varying concentrations in teeth, bone, and drinking water. [40], The Centers for Disease Control and Prevention developed recommendations for water fluoridation that specify requirements for personnel, reporting, training, inspection, monitoring, surveillance, and actions in case of overfeed, along with technical requirements for each major compound used. [97] By 2006, 69.2% of the U.S. population on public water systems were receiving fluoridated water, amounting to 61.5% of the total U.S. population; 3.0% of the population on public water systems were receiving naturally occurring fluoride. Issues studied have included fluoride concentrations in groundwater and downstream rivers; lawns, gardens, and plants; consumption of plants grown in fluoridated water; air emissions; and equipment noise. Molecular Weight 144.09 . View information & documentation regarding Fluosilicic acid, including CAS, MSDS & more. Palache, C., Berman, H., and Frondel, C. (1951) Dana’s System of Mineralogy, Volume II: Halides, Nitrates, Borates, Carbonates, Sulfates, Phosphates, Arsenates, Tungstates, Molybdates, etc. [105], U.S. data from 1974 to 1992 indicate that when water fluoridation is introduced into a community, there are significant decreases in the number of employees per dental firm and the number of dental firms. Gives off irritating or toxic fumes (or gases) in a fire. Component Compounds: CID 14917 (Hydrofluoric acid) CID 24556 (Silicon … [61] In 2010, approximately 60 gallons of fluoride were released into the water supply in Asheboro, North Carolina in 90 minutes—an amount that was intended to be released in a 24-hour period. [15] A systematic review found low-quality evidence to support the practice, but also concluded that further studies were needed. [94] By present-day standards these and other pioneering studies were crude, but the large reductions in cavities convinced public health professionals of the benefits of fluoridation. [92], The foundation of water fluoridation in the U.S. was the research of the dentist Frederick McKay (1874–1959). Monomers, Polymer Intermediates, CVD/Pre-Ceramic. A blank cell indicates the fabric has not been tested. [15] Its introduction is considered the main reason for the decline in tooth decay in industrialized countries,[3] and toothpaste appears to be the single common factor in countries where tooth decay has declined. Fluorosilicic acid (Hydrofluorosilicic acid) is manufactured by two different processes, resulting in products with different characteristics. John Wiley and Sons, Inc., New York, 7th edition. [74] Toothpaste is the only realistic fluoride strategy in many low-income countries, where lack of infrastructure renders water or salt fluoridation infeasible. In case of fire in the surroundings, use appropriate extinguishing media. By 2000, however, the topical effects of fluoride (in both water and toothpaste) were well understood, and it had become known that a constant low level of fluoride in the mouth works best to prevent cavities. [45], Previous recommendations were based on evaluations from 1962, when the U.S. specified the optimal level of fluoride to range from 0.7 to 1.2 mg/L (milligrams per liter, equivalent to parts per million), depending on the average maximum daily air temperature; the optimal level is lower in warmer climates, where people drink more water, and is higher in cooler climates. [32] A 2016 review of studies published between 1995 to 2013 found that water fluoridation in the U.S. was cost-effective, and that it was more so in larger communities. [7] Some bottled waters contain undeclared fluoride, which can be present naturally in source waters, or if water is sourced from a public supply which has been fluoridated. As such, it has been used … [51], Fluoride may also prevent cavities in adults of all ages. In infants 80–90% of absorbed fluoride is retained, with the rest excreted, mostly via urine; in adults about 60% is retained. Substance Data Source: TOXNET. • DNA damage was caused by fluorosilicic acid in mesenchymal stem cells. [63] Although it has been hypothesized that hydrofluosilicic acid and sodium silicofluoride might increase human lead uptake from water, a 2006 statistical analysis did not support concerns that these chemicals cause higher blood lead concentrations in children. Fluorosilicic Acid is manufactured from the mineral apatite, which is mined for its high phosphate content. [9] However this was based on older studies which failed to control for numerous variables, such as increasing sugar consumption as well as other dental strategies. After the sugar is gone, some of the mineral loss can be recovered—or remineralized—from ions dissolved in the saliva. Advertisement. It is used in sterilization of equipment, electroplating, tanning of animal hides, … A smaller amount is produced from HF and silica resulting in a purer product at slightly higher strength. Identification Product form : Substance Substance name : Fluorosilicic Acid (FSA) Chemical name : Hydro Fluorosilicic Acid (HSA) Product code : M17200 1.2. MENU MENU Alibaba.com. [63], The effect of water fluoridation on the natural environment has been investigated, and no adverse effects have been established. It has various applications such as electroplating, sterilization, oil well acidizing, and other applications. US $400.00-$1200 / Metric Ton. Sigma-Aldrich offers a number of Fluosilicic acid products. Near neutral pH, hexafluorosilicate salts hydrolyze rapidly according to this equation:[8]. Serged and bound seams are degraded by some hazardous liquid chemicals, such as strong acids, and should not be worn when these chemicals are present. [22][23], The goal of water fluoridation is to prevent tooth decay by adjusting the concentration of fluoride in public water supplies. drinking water, fluorine, fresh water, toxicity, water treatment. Fluorosilicic acid (H 2 SiF 6) is the most commonly used additive for water fluoridation in the United States. [43], In 2011, the U.S. Department of Health and Human Services (HHS) and the U.S. Environmental Protection Agency (EPA) lowered the recommended level of fluoride to 0.7 mg/L. Linear Formula: H 2 SiF 6. [2] Tooth decay (dental caries) is one of the most prevalent chronic diseases worldwide. Causes burns. Fluorosilicic acid is also referred to as hydrofluorosilicate, FSA, or HFS. [7], Tooth decay remains a major public health concern in most industrialized countries, affecting 60–90% of schoolchildren and the vast majority of adults. H332 Harmful if inhaled. A systematic review of published studies", "U.S. Public Health Service Recommendation for Fluoride Concentration in Drinking Water for the Prevention of Dental Caries", "Dental fluorosis: exposure, prevention and management", "Asheboro notifies residents of over-fluoridation of water", "Water fluoridation and the environment: current perspective in the United States", "Blood lead concentrations in children and method of water fluoridation in the United States, 1988-1994", "How to maintain a cariostatic fluoride concentration in the oral environment", "Dental fluorosis: chemistry and biology", "Strategies to enhance the biological effects of fluoride on dental biofilms", "Fluoride and organic weak acids as modulators of microbial physiology", "Present and future approaches for the control of caries", "Oral health in the United States: the post-fluoride generation", "Global affordability of fluoride toothpaste", "Fluoridated milk for preventing dental caries", "Are sugar substitutes also anticariogenic? Details of the supplier of the safety data sheet PCS Sales (USA), Inc. 1101 Skokie Blvd. Other than its addition into tap water, this acid is also used as a wood preservative, is present in cleaning compounds and plays a role in the production of glass (4). Again, some of the HF in turn reacts with silicate minerals, which are an unavoidable constituent of the mineral feedstock, to give silicon tetrafluoride. Hi, Going to use PVC pipes for Hydro-Fluorosilicic Acid (20% conc) in a chemical dosing system. Details of the supplier of the safety data sheet PCS Sales (USA), Inc. 1101 Skokie Blvd. [86][87], The history of water fluoridation can be divided into three periods. [2][46] Dental sealants are cost-effective only when applied to high-risk children and teeth. [59] The World Health Organization recommends a guideline maximum fluoride value of 1.5 mg/L as a level at which fluorosis should be minimal. [15] Dental sealants are effective as well,[24] with estimates of prevented cavities ranging from 33% to 86%, depending on age of sealant and type of study. The Australian government states that water fluoridation is the most effective way to achieve fluoride exposure that is community-wide. [94], In the 1930s and early 1940s, H. Trendley Dean and colleagues at the newly created U.S. National Institutes of Health published several epidemiological studies suggesting that a fluoride concentration of about 1 mg/L was associated with substantially fewer cavities in temperate climates, and that it increased fluorosis but only to a level that was of no medical or aesthetic concern. Fluorosilicic acid is used in the tanning of animal hides and skins, in ceramics and glass, in technical paints, in oil well acidizing, in the manufacture of hydrogen fluoride, for the sterilization of equipment (e.g., in brewing and bottling establishments and for copper and brass vehicles), and in electroplating. Details: About. A smaller amount is produced from HF and silica resulting in a purer product at slightly higher strength. [8], As of November 2012, a total of about 378 million people worldwide received artificially fluoridated water. [31] The effectiveness of water fluoridation can vary according to circumstances such as whether preventive dental care is free to all children. [3] For example, in Finland and Germany, tooth decay rates remained stable or continued to decline after water fluoridation stopped in communities with widespread fluoride exposure from other sources. Fluorosilicic acid (Hydrofluorosilicic acid) is manufactured by two different processes, resulting in products with different characteristics. [67] When fluoride ions are present in plaque fluid along with dissolved hydroxyapatite, and the pH is higher than 4.5,[66] a fluorapatite-like remineralized veneer is formed over the remaining surface of the enamel; this veneer is much more acid-resistant than the original hydroxyapatite, and is formed more quickly than ordinary remineralized enamel would be. [97] To test the hypothesis that adding fluoride would prevent cavities, Dean and his colleagues conducted a controlled experiment by fluoridating the water in Grand Rapids, Michigan, starting 25 January 1945. [103] By comparison, fluoride toothpaste costs an estimated $9–$18 per person-year, with the incremental cost being zero for people who already brush their teeth for other reasons; and dental cleaning and application of fluoride varnish or gel costs an estimated $101 per person-year. [57] Other sources include dental products other than toothpaste; air pollution from fluoride-containing coal or from phosphate fertilizers; trona, used to tenderize meat in Tanzania; and tea leaves, particularly the tea bricks favored in parts of China. [46], These standards are not appropriate for all parts of the world, where fluoride levels might be excessive and fluoride should be removed from water, and is based on assumptions that have become obsolete with the rise of air conditioning and increased use of soft drinks, processed food, fluoridated toothpaste, and other sources of fluorides. Thus formed, the silicon tetrafluoride reacts further with HF. These corrosion data are mainly based on results of general corrosion laboratory tests, ... (Used only where there are no actual data to estimate the risk of localised corrosion instead of p or s). The offered acid is processed by our pool of experts in compliance with the chemical industry set norms. [32] Other reviews have found not enough evidence to determine if water fluoridation reduces oral-health social disparities. [44] In 2015, the U.S. Food and Drug Administration (FDA), based on the recommendation of the U.S. Public Health Service (PHS) for fluoridation of community water systems, recommended that bottled water manufacturers limit fluoride in bottled water to no more than 0.7 milligrams per liter (mg/L)(milligrams per liter, equivalent to parts per million). [1] It is normally accomplished by adding one of three compounds to the water: sodium fluoride, fluorosilicic acid, or sodium fluorosilicate. Use of the Substance/Preparation Recommended use : - Chemical intermediate However, these values differ greatly among the world's regions: for example, in Sichuan, China the average daily fluoride intake is only 0.1 mg/day in drinking water but 8.9 mg/day in food and 0.7 mg/day directly from the air due to the use of high-fluoride soft coal for cooking and drying foodstuffs indoors. [83][107] For deprived groups in both maturing and matured countries, international and national agencies and dental associations across the world support the safety and effectiveness of water fluoridation. Related ammonium and barium salts are produced similarly for other applications. It also act as a neutralizer for alkalis, which may boost industry growth. Depending on location, the fluoride is added to milk, to powdered milk, or to yogurt. Fluorosilicic acid altered bone mineralization in mesenchymal stem cells. CAS-Number 16961-83-4: Flash Point n/a: Boiling Point n/a: Emergency Response Guide No. IN ALL CASES CONSULT A DOCTOR! In three other West European countries, Greece, Austria and the Netherlands, the legal framework for production and marketing of fluoridated edible salt exists. [35] A 1992 census found that, for U.S. public water supply systems reporting the type of compound used, 63% of the population received water fluoridated with fluorosilicic acid, 28% with sodium fluorosilicate, and 9% with sodium fluoride. The product is used as a chemical intermediate for aluminum trifluoride, cryolite and other fluorosilicates. Hexafluorosilicic acid (identified as hydrofluorosilicic acid on the label) along with oxalic acid are the active ingredients used in Iron Out rust-removing cleaning products, which are essentially varieties of laundry sour. Hexafluorosilicate is an octahedral anion; the Si–F bond distances are 1.71 Å. [3] Technically, this fluoride does not prevent cavities but rather controls the rate at which they develop. This assists in preventing cavities in teeth. [57] A 2009 systematic review indicated that fluorosis is associated with consumption of infant formula or of water added to reconstitute the formula, that the evidence was distorted by publication bias, and that the evidence that the formula's fluoride caused the fluorosis was weak. Dean and his colleagues assumed that fluoride's protection against cavities was also pre-eruptive, and this incorrect assumption was accepted for years. Achievements in public health, 1900-1999: fluoridation of drinking water to prevent dental caries", "One in a million: the first community trial of water fluoridation", "Studies on mass control of dental caries through fluoridation of the public water supply", "Collaboration, vision and reality: water fluoridation in New Zealand (1952-1968)", "Salt fluoridation--an alternative in automatic prevention of dental caries", "Economic Evaluation of Community Water Fluoridation: A Community Guide Systematic Review", "Equilibrium effects of public goods: the impact of community water fluoridation on dentists", "When public action undermines public health: a critical examination of antifluoridationist literature", "A critique of recent economic evaluations of community water fluoridation", "The science and ethics of water fluoridation", https://en.wikipedia.org/w/index.php?title=Water_fluoridation&oldid=998776044, Wikipedia indefinitely semi-protected pages, Creative Commons Attribution-ShareAlike License, This page was last edited on 7 January 2021, at 00:10. [104] A 2002 U.S. review estimated that on average, sealing first permanent molars saves costs when they are decaying faster than 0.47 surfaces per person-year whereas water fluoridation saves costs when total decay incidence exceeds 0.06 surfaces per person-year. In some locations, notably parts of Africa, China, and India, natural fluoridation exceeds recommended levels. [65] When enough acid is produced to lower the pH below 5.5,[66] the acid dissolves carbonated hydroxyapatite, the main component of tooth enamel, in a process known as demineralization. [16], Public water fluoridation was first practiced in the U.S.[17] As of 2012, 25 countries have artificial water fluoridation to varying degrees, 11 of them have more than 50% of their population drinking fluoridated water. Although no major differences between natural and artificial fluoridation were apparent, the evidence was inadequate for a conclusion about any differences. It is an inexpensive liquid by-product of phosphate fertilizer manufacture. Molecular Weight: … Fluoridation does not affect the appearance, taste, or smell of drinking water. [2] Fluoridated water operates on tooth surfaces: in the mouth, it creates low levels of fluoride in saliva, which reduces the rate at which tooth enamel demineralizes and increases the rate at which it remineralizes in the early stages of cavities. Protection of Young People Directive. [96] Other studies found no other significant adverse effects even in areas with fluoride levels as high as 8 mg/L. It reacts faster with t-butyldimethysilyl (TBDMS) ethers than triisopropylsilyl (TIPS) ethers. Fluorosilicic acid is also used in different applications like metal surface treatment, textile processing, water fluoridation, hydrogen fluoride, metal surface treatment, aluminum fluoride, oil well acidizing, hide processing, and silicofluorides electroplating. Get InChI Search by SMILES. Concentrations of fluoride in salt range from 90 to 350 mg/kg, with studies suggesting an optimal concentration of around 250 mg/kg. New Zealand, which led the world in per-capita sugar consumption and had the world's worst teeth, began fluoridation in 1953, and by 1968 fluoridation was used by 65% of the population served by a piped water supply. [80], A 2007 Australian review concluded that water fluoridation is the most effective and socially the most equitable way to expose entire communities to fluoride's cavity-prevention effects. (H3O)2SiF6 is also produced as a by-product from the production of phosphoric acid from apatite and fluorapatite. [81] A 2007 Italian review suggested that water fluoridation may not be needed, particularly in the industrialized countries where cavities have become rare, and concluded that toothpaste and other topical fluoride are the best way to prevent cavities worldwide. The majority of the hexafluorosilicic acid is converted to aluminium fluoride and synthetic cryolite. It comes in varying strengths, typically 23–25%; because it contains so much water, shipping can be expensive. ... Fluorosilicic acid solution. In most drinking waters, over 95% of total fluoride is the F− ion, with the magnesium–fluoride complex (MgF+) being the next most common. [12] There is no clear association between fluoridation and cancer or deaths due to cancer, both for cancer in general and also specifically for bone cancer and osteosarcoma. [15], "Fluorosilicate" redirects here. • Fluorosilicic acid altered bone mineralization in mesenchymal stem cells. The Slovak Republic had the equipment to treat salt by 2005; in the other four countries attempts to introduce fluoridated salt were not successful. Relevant identified uses of the substance or mixture and uses advised against Use of the substance/mixture : Industrial use 1.3. In the second half they speculated that fluoride would protect against tooth decay, proposed supplementing the diet with fluoride, and observed mottled enamel (now called severe dental fluorosis) without knowing the cause. It is a good descaler, soap-scum remover and a registered anti-bacterial agent. FLUOROSILICIC ACID: ICSC: 1233: Hexafluorosilicic acid Dihydrogen hexafluorosilicate Fluosilicic acid Hydrosilicofluoric acid: October 2004: CAS #: 16961-83-4: UN #: 1778 EC Number: 241-034-8 ACUTE HAZARDS PREVENTION FIRE FIGHTING; FIRE & EXPLOSION: Not combustible. [29] The motivation for fluoridation of salt or water is similar to that of iodized salt for the prevention of congenital hypothyroidism and goiter. The conversion to aluminium trifluoride is described as: Hexafluorosilicic acid is also converted to a variety of useful hexafluorosilicate salts. Carbon-nitrogen compounds, alcohols, mercaptans, monoterpenes, acetates, aldehydes, ketones, SF6, PH3, and other fire gases in coal-mining waste heaps of Upper Silesian Coal Basin (Poland) – a re-investigation by means of in-situ FTIR extrernal database approach. Fluoride mouthwash and gel are about as effective as fluoride toothpaste; fluoride varnish prevents about 45% of cavities. A smaller amount is produced from HF and silica resulting in a purer product at slightly higher strength it is used in sterilization of equipment, electroplating, tanning of animal hides, … [57], Although a 1989 workshop on cost-effectiveness of cavity prevention concluded that water fluoridation is one of the few public health measures that save more money than they cost, little high-quality research has been done on the cost-effectiveness and solid data are scarce. Kruszewski, Ł., Fabiańska, M.J., Segit, T., Kusy, D., Motyliński, R., Ciesielczuk, J., Deput, E., 2020. HAZARDS IDENTIFICATION EMERGENCY OVERVIEW Corrosive. The majority of the hexafluorosilicic acid is converted to aluminium fluoride and synthetic cryolite. Rivers and lakes generally contain fluoride levels less than 0.5 mg/L, but groundwater, particularly in volcanic or mountainous areas, can contain as much as 50 mg/L. "[84][85] This change was often motivated by political opposition to water fluoridation, but sometimes the need for water fluoridation was met by alternative strategies. These materials are central to the conversion of aluminium ore into aluminium metal. This approach is therefore not accepted in most countries in the world. [18] In 2010, about 66% of the U.S. population was receiving fluoridated water. Metal-Organics. ", "Reviews of evidence on interventions to prevent dental caries, oral and pharyngeal cancers, and sports-related craniofacial injuries", Israel Has Officially Banned Fluoridation of Its Drinking Water, "Salt fluoridation in Europe and in Latin America – with potential worldwide", "Salt fluoridation in Central and Eastern Europe", "Dr. Erhardts ("Hunter'sche") Fluoridpastillen", "Achievements in public health, 1900–1999: Fluoridation of drinking water to prevent dental caries", "From the Centers for Disease Control and Prevention. [9] Most European countries have experienced substantial declines in tooth decay, though milk and salt fluoridation is widespread in lieu of water fluoridation. 8. [12] The World Health Organization reports that water fluoridation, when feasible and culturally acceptable, has substantial advantages, especially for subgroups at high risk,[8] while the European Commission finds no benefit to water fluoridation compared with topical use. [14] Higher concentrations of fluorine are found in alkaline volcanic, hydrothermal, sedimentary, and other rocks derived from highly evolved magmas and hydrothermal solutions, and this fluorine dissolves into nearby water as fluoride.
