[13], Fluoride can occur naturally in water in concentrations well above recommended levels, which can have several long-term adverse effects, including severe dental fluorosis, skeletal fluorosis, and weakened bones; water utilities in the developed world reduce fluoride levels to regulated maximum levels in regions where natural levels are high, and the WHO and other groups work with countries and regions in the developing world with naturally excessive fluoride levels to achieve safe levels. This Fluosilicic Acid is extensively used as fluoridation agents for drinking water. More... Molecular Weight: 144.091 g/mol. Fluorosilicic acid (Hydrofluorosilicic acid) is manufactured by two different processes, resulting in products with different characteristics. 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. The largest production of the acid is as a byproduct of phosphate fertilizer manufacture. [28] Oral disease is the fourth most expensive disease to treat. [74] Toothpaste is the only realistic fluoride strategy in many low-income countries, where lack of infrastructure renders water or salt fluoridation infeasible. Hand, Arm and Body Protection: Prevent contact with skin by use of acid-proof clothing, gloves and shoes. [13] Fluoride's effects depend on the total daily intake of fluoride from all sources. The largest production of the acid is as a byproduct of phosphate fertilizer manufacture. Like HF, this compound attacks glass and therefore must be stored in plastic containers. Find pure quality fluorosilicic acid that retain acidic properties and serve purposes optimally at Alibaba.com. 8. [9], Health and dental organizations worldwide have endorsed its safety and effectiveness. A 2007 meta-analysis by CDC researchers found that water fluoridation prevented an estimated 27% of cavities in adults, about the same fraction as prevented by exposure to any delivery method of fluoride (29% average). It can be accomplished by percolating water through granular beds of activated alumina, bone meal, bone char, or tricalcium phosphate; by coagulation with alum; or by precipitation with lime. Fluorosilicic acid (Hydrofluorosilicic acid) is manufactured by two different processes, resulting in products with different characteristics. [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. [68] Although some systemic (whole-body) fluoride returns to the saliva via blood plasma, and to unerupted teeth via plasma or crypt fluid, there is little data to determine what percentages of fluoride's anticavity effect comes from these systemic mechanisms. Identification Product form : Substance Substance name : Fluorosilicic Acid (FSA) Chemical name : Hydro Fluorosilicic Acid (HSA) Product code : M17200 1.2. The use of fluoride in its various forms is the foundation of tooth decay prevention throughout Europe; several countries have introduced fluoridated salt, with varying success: in Switzerland and Germany, fluoridated salt represents 65% to 70% of the domestic market, while in France the market share reached 60% in 1993 but dwindled to 14% in 2009; Spain, in 1986 the second West European country to introduce fluoridation of table salt, reported a market share in 2006 of only 10%. Get InChI Search by SMILES. [9][49] Studies in the U.S. in the 1950s and 1960s showed that water fluoridation reduced childhood cavities by fifty to sixty percent, while studies in 1989 and 1990 showed lower reductions (40% and 18% respectively), likely due to increasing use of fluoride from other sources, notably toothpaste, and also the 'halo effect' of food and drink that is made in fluoridated areas and consumed in unfluoridated ones. Molecular Weight 144.09 . Fluorosilicic Acid Compatibility with PVC Nalsoft (Mechanical) (OP) 19 Mar 20 05:03. PRODUCT AND COMPANY IDENTIFICATION 1.1. FLUOROSILICIC ACID, 23-25% 1. The U.S. Institute of Medicine has established Dietary Reference Intakes for fluoride: Adequate Intake values range from 0.01 mg/day for infants aged 6 months or less, to 4 mg/day for men aged 19 years and up; and the Tolerable Upper Intake Level is 0.10 mg/kg/day for infants and children through age 8 years, and 10 mg/day thereafter. Fluorosilicic acid is used in fluoridation of water that maintains fluoride levels in the water. [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. [2][4] Defluoridation is needed when the naturally occurring fluoride level exceeds recommended limits. Handling, Storage, and Precautions: fluorosilicic acid is toxic and very corrosive. [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. Relevant identified uses of the substance or mixture and uses advised against Use of the substance/mixture : Industrial use 1.3. [69] Also, although fluoride affects the physiology of dental bacteria,[70] its effect on bacterial growth does not seem to be relevant to cavity prevention. Thanks in advance . This list contains biological and chemical agents, in accordance with Art. [14] In many industrialized countries swallowed toothpaste is the main source of fluoride exposure in unfluoridated communities. Advertisement. [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. Because fluoride levels in water are usually controlled by the solubility of fluorite (CaF2), high natural fluoride levels are associated with calcium-deficient, alkaline, and soft waters. [2] In affluent countries the cost of salt fluoridation is also negligible; developing countries may find it prohibitively expensive to import the fluoride additive. About 40 million worldwide received water that was naturally fluoridated to recommended levels. Eye and Face Protection: Use tight-fitting chemical splash goggles and a full-face shield, 8 inch minimum. Both the fumes and very short contact with the liquid can cause severe and painful burns. [15] A systematic review found low-quality evidence to support the practice, but also concluded that further studies were needed. (1955–1960). At the concentration usually used for water fluoridation, 99% hydrolysis occurs and the pH drops. Performance Products. Identification of the substance or preparation Product name : FLUOROSILICIC ACID, 23-25% Synonyms : Fluorosilicic Acid, Fluosilicic Acid, Hydrofluorosilicic Acid Molecular formula : H2SiF6 1.2. Molecular Weight: … Used in water fluoridation, in hardening cement and ceramics, as a wood preservative. [13] A 2007 Australian systematic review used the same inclusion criteria as York's, plus one additional study. [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. Decomposes when heated, with possible emanation of toxic hydrofluoric acid vapours. It is an inexpensive liquid by-product of phosphate fertilizer manufacture. "[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. [48] The FDA states that bottled water products labeled as de-ionized, purified, demineralized, or distilled have been treated in such a way that they contain no or only trace amounts of fluoride, unless they specifically list fluoride as an added ingredient. The review found that the evidence was of moderate quality: few studies attempted to reduce observer bias, control for confounding factors, report variance measures, or use appropriate analysis. H335 May cause … [81] In the U.S., water fluoridation is more cost-effective than other methods to reduce tooth decay in children, and a 2008 review concluded that water fluoridation is the best tool for combating cavities in many countries, particularly among socially disadvantaged groups. Tooth decay is an infectious disease, the key feature of which is an increase within dental plaque of bacteria such as Streptococcus mutans and Lactobacillus. FLUOROSILICIC ACID 1778 FLUOROSILICIC ACID 1778 1778 FLUOROSILICIC ACID 14.1 UN Number 14.2 Proper Shipping Name No information provided. 77, No. [9] Most European countries have experienced substantial declines in tooth decay, though milk and salt fluoridation is widespread in lieu of water fluoridation. Sodium fluorosilicate: a dry salt additive, dissolved into a solution before being added to water. The Slovak Republic had the equipment to treat salt by 2005; in the other four countries attempts to introduce fluoridated salt were not successful. 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. Product name FLUOROSILICIC ACID (22% SOLUTION) 2.HAZARDS IDENTIFICATION CLASSIFIED AS HAZARDOUS ACCORDING TO SAFE WORK AUSTRALIA CRITERIA 2.2 GHS Label elements Signal word DANGER H302 Harmful if swallowed. [12] The European Commission review states "No obvious advantage appears in favour of water fluoridation compared with topical prevention". [6] These materials are central to the conversion of aluminium ore into aluminium metal. INTRODUCTION. 36.4% Response Rate "Good experience" Contact Supplier . English Sourcing Solutions ... Fluorosilicic acid liquid H2SiF6. CAS-Number 16961-83-4: Flash Point n/a: Boiling Point n/a: Emergency Response Guide No. [58] In the U.S. the decline in tooth decay was accompanied by increased fluorosis in both fluoridated and unfluoridated communities; accordingly, fluoride has been reduced in various ways worldwide in infant formulas, children's toothpaste, water, and fluoride-supplement schedules. The rate of hydrolysis increases with pH. Details of the supplier of the safety data sheet PCS Sales (USA), Inc. 1101 Skokie Blvd. read more... Sree Vani Fluoride. [24] Another of the goals was to bridge inequalities in dental health and dental care. Linear Formula H 2 SiF 6. The data suggest that some dentists respond to the demand shock by moving to non-fluoridated areas and by retraining as specialists. [33] Further research showed that moderate fluoridation prevents tooth decay.[34]. Hexafluorosilicic acid can also be produced by treating silicon tetrafluoride with hydrofluoric acid. Label 8 Packing group DOT, IMDG, IATA II Environmental hazards: Marine pollutant (IMDG): No Special precautions for user Warning: Corrosive substances EMS Number: F-A,S-B Segregation … [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. Some countries and communities have discontinued fluoridation, while others have expanded it. Metal-Organics. The majority of the hexafluorosilicic acid is converted to aluminium fluoride and synthetic cryolite. Inhalation of the vapors may cause lung edema. There is also scientific evidence that fluoride in large amounts can lead to damage to health. Three such outbreaks were reported in the U.S. between 1991 and 1998, caused by fluoride concentrations as high as 220 mg/L; in the 1992 Alaska outbreak, 262 people became ill and one person died. [96] Other studies found no other significant adverse effects even in areas with fluoride levels as high as 8 mg/L.

Hexafluorosilicic acid is also used as an electrolyte in the Betts electrolytic process for refining lead. At the commonly recommended dosage, the only clear adverse effect is dental fluorosis, which can alter the appearance of children's teeth during tooth development; this is mostly mild and is unlikely to represent any real effect on aesthetic appearance or on public health. [56] Compared to water naturally fluoridated at 0.4 mg/L, fluoridation to 1 mg/L is estimated to cause additional fluorosis in one of every 6 people (95% CI 4–21 people), and to cause additional fluorosis of aesthetic concern in one of every 22 people (95% CI 13.6–∞ people). IN ALL CASES CONSULT A DOCTOR! [1] It is normally accomplished by adding one of three compounds to the water: sodium fluoride, fluorosilicic acid, or sodium fluorosilicate. [3] Authorities' views on the most effective fluoride therapy for community prevention of tooth decay are mixed; some state water fluoridation is most effective, while others see no special advantage and prefer topical application strategies. Anthony, J.W., Bideaux, R.A., Bladh, K.W., and Nichols, M.C. Fluorosilicic acid is the most used additive for water fluoridation. In infants 80–90% of absorbed fluoride is retained, with the rest excreted, mostly via urine; in adults about 60% is retained. Listen. Hexafluorosilicic acid is also used as an electrolyte in the Betts electrolytic process for refining lead. HAZARDS IDENTIFICATION EMERGENCY OVERVIEW Corrosive. [9] In the US mild or very mild dental fluorosis has been reported in 20% of the population, moderate fluorosis in 2% and severe fluorosis in less than 1%. FLUOROSILICIC ACID Transport hazard class(es) DOT Class 8 Corrosive substances. 1778. In some locations, notably parts of Africa, China, and India, natural fluoridation exceeds recommended levels. Sodium fluoride: a dry salt additive, typically used in small water systems, dissolved into a solution before being added to water. (1997) Handbook of Mineralogy, Volume III: Halides, Hydroxides, Oxides. [15], "Fluorosilicate" redirects here. Matching up with the ever-increasing requirements of the customers, our company offers standard quality assortment of Fluosilicic Acid. (H3O)2SiF6 is also produced as a by-product from the production of phosphoric acid from apatite and fluorapatite. Assuming the worst case, with the lowest estimated effectiveness and highest estimated operating costs for small cities, fluoridation costs an estimated $17–$26 per saved tooth-decay surface, which is lower than the estimated $100 to restore the surface[2] and the estimated $169 average discounted lifetime cost of the decayed surface, which includes the cost to maintain the restored tooth surface. It is also employed as an impregnating ingredient to preserve wood and harden masonry and for the … [9] This increases to 40% when considering fluorosis of any level not of aesthetic concern. Relevant identified uses of the substance or mixture and uses advised against Use of the substance/mixture : Industrial use 1.3. 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. For example, milk powder fluoridation is used in rural Chilean areas where water fluoridation is not technically feasible. Sources of Fluoride Additives. So how does this end up in your drinking water? In case of fire in the surroundings, use appropriate extinguishing media. [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. Product Code: SIF4920.0 Cas No: 16961-83-4. 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. 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. [55] The 2015 Cochrane review estimated that for a fluoride level of 0.7 ppm the percentage of participants with fluorosis of aesthetic concern was approximately 12%. T. C1. ... Fluorosilicic acid solution. The increasing use of fluorosilicic acid in fluoridation of drinking water is a major factor contributing to the growth of the fluorosilicic acid market. Corrosive to metals and tissue. 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. [17] It has been introduced to varying degrees in many countries and territories outside the U.S., including Argentina, Australia, Brazil, Canada, Chile, Colombia, Hong Kong, Ireland, Israel, Korea, Malaysia, New Zealand, the Philippines, Serbia, Singapore, Spain, the UK, and Vietnam. 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. [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. [12] There is no clear evidence of other adverse effects from water fluoridation. Use of the Substance/Preparation Recommended use : - Chemical intermediate 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. Used in water fluoridation, in hardening cement and ceramics, as a wood preservative. [24] Although it is rarely life-threatening, tooth decay can cause pain and impair eating, speaking, facial appearance, and acceptance into society,[25] and it greatly affects the quality of life of children, particularly those of low socioeconomic status. 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). [13], Reviews have shown that water fluoridation reduces cavities in children. HAZARDS IDENTIFICATION EMERGENCY OVERVIEW Corrosive. [63], Fluoride exerts its major effect by interfering with the demineralization mechanism of tooth decay. From the beginning ICL Rotem used HDPE, 316 stainless steel and rubberized steel pipes for the transport of fluorosilicic acid. 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. [94], McKay's work had established that fluorosis occurred before tooth eruption. Corrosive to metals and tissue. Label 8 Class 8 (C1) Corrosive substances Label 8 IMDG, IATA Class 8 Corrosive substances. For example, Jamaica has just one salt producer, but a complex public water supply; it started fluoridating all salt in 1987, achieving a decline in cavities. … [57], The effectiveness of salt fluoridation is about the same as that of water fluoridation, if most salt for human consumption is fluoridated. Fluorosis can be prevented by monitoring all sources of fluoride, with fluoridated water directly or indirectly responsible for an estimated 40% of risk and other sources, notably toothpaste, responsible for the remaining 60%. A person living in an area with fluoridated water may experience rises of fluoride concentration in saliva to about 0.04 mg/L several times during a day. UN 1778 (5) Packing Group. After the sugar is gone, some of the mineral loss can be recovered—or remineralized—from ions dissolved in the saliva. [14], The views on the most effective method for community prevention of tooth decay are mixed. Label 8 Packing group DOT, IMDG, IATA II Environmental hazards: Marine pollutant (IMDG): No Special precautions for user Warning: Corrosive substances EMS Number: F-A,S-B Segregation groups Acids Transport in bulk according to … Dublin, Oct. 26, 2020 (GLOBE NEWSWIRE) -- The "Fluorosilicic Acid Market - Growth, Trends, and Forecast (2020 - 2025)" report has been added to ResearchAndMarkets.com's offering. [3] A 2004 World Health Organization review stated that water fluoridation, when it is culturally acceptable and technically feasible, has substantial advantages in preventing tooth decay, especially for subgroups at high risk. The offered acid is processed by our pool of experts in compliance with the chemical industry set norms. A blank cell indicates the fabric has not been tested. [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.
