Fluorosilicic Acid Market Size - By Grade, Application Analysis, Share, Growth Forecast, 2025-2034

Fluorosilicic Acid Market Size

The global fluorosilicic acid market was valued at USD 502.8 million in 2024 and is estimated to grow at a CAGR of over 6.9% from 2025 to 2034.
 

With the growth in pollution of groundwater and surface water, there is an increasing need for water treatment. Fluorosilicic acid is a colorless, fuming, and strongly odorous liquid which is a waste of the production of hydrogen fluoride and phosphoric acid. Often, it is neutralized to render it harmless with limestone or milk of lime. It is commercially distributed as an aqueous solution of both pure and technical grade, with a concentration of up to 70 percent. It is used in cement, ceramics, and steel liquor, water fluoridation, cement and wooden surface hardeners, as well as in textile and oil well operations, and in metal and electroplating.
 

Fluorosilicic acid has a large number of applications. It is used in the sterilization of articles, commercial laundry where it acts as a neutralizing agent, and in rust removal. The increasing consumption of particular acids by the textile industry with a focus on rust and stain removal is anticipated to promote the market.

Fluorosilicic Acid Market Trends

The growing need of fluorsilicic acid during water fluoridation indicates that fluorsilic acid has its place in maintaining dental health and as a result is commonly used in the modernized water supply. Furthermore, the expanding market of dental applications further enhances its importance for non-invasive dentistry. At the same time, the growth of the textile market also drives the consumption of fluorosilicic acid as it is used in several textile processes.
 

Fluorosilicic Acid Market Analysis

Due to advancements in manufacturing processes and blooming demand across several industries, the fluorsilic acid market has rapidly escalated. Production efficiency as well as the cost has significantly improved due to recent breakthroughs in production processes and technology. Applications such as chemical synthesis, aluminium production and water fluoridation are proposing the growth of this market. Firms are adopting new technologies to stay competitive while making it their goal to reduce their carbon footprint.
 

The 40% grade fluorosilicic acid was worth USD 233.6 million in 2024 and is expected to grow at a CAGR rate of 6.7% from the year 2025 until 2034. 40% grade is added in the public water supply to avoid tooth decay and strengthen the fluoride levels. Some of the leaders in the flurosilicic acid market are the U.S. Public Health Service, the American Dental Association, the American Academy of Pediatrics and the WHO. Their endorsement will help the market to thrive further.
 

There is a significant rise in geriatric population along with great variety of denture products which is driving growth of oral care products which in turn is driving growth of the industry. Moreover, the 40% grade fluorosilicic acid market is boosted by increasing regulations by government agencies controlling water pollution and also the increasing budgets by government agencies towards water treatment. This 40% grade chemical mainly is used in the textile industry as a pH cleaner and adjuster.
 

Silicofluorides segment was valued at USD 107.5 million in 2024 and gained 7.1% CAGR from 2025 to 2034. The steady rise of urban population, increasing levels of water pollution, and improving levels of health awareness are positive factors at play. On the other hand, the global increase in water consumption, as coupled with the other factors aforementioned, are likely to increase the demand for water chemicals Market. Moreover, the anticipated increase in industrial activities, as well as the increasing need for safe drinking water due to health reasons, will help increase revenues in the fluorosilicic acid industry.
 

There is a growing trend of using Industrial-grade fluoride chemicals in water that is promoted as a measure to prevent dental caries, this trend is likely to grow in popularity over the coming years. With improving consumer preferences for more natural ingredients in floss and mouthwash, product demand is expected to benefit from this shift in the near term. Furthermore, with the shift in consumer perception of focusing more and more on avoiding the onset of dental caries, alongside the increasing quest to finding safe and efficient ingredients for cavity prevention for all ages, the aforementioned trends will most probably benefit the fluorosilicic acid industry.
 

U.S. public health authorities suggest the consistent use of water fluoridation as a method protected against dental caries with minimal risk of exposing the population to dental fluorosis. According to WHO data, the number of caries of permanent teeth is the most prevalent health disorder in the world. Additionally, the Australian Department of Health claims that the practice of water fluoridation is an efficient and safe public health intervention for people of all ages.
 

In 2024 the U.S. Fluorosilicic acid market was reported USD 170.5 million. U.S.  government legally obliges municipal corporations to include fluoridating agents in public water for drinking purposes. While the American Association of Public Health Dentists links the practice of water friending to the prevention of dental caries, it is recommended that its application be extended to all communal water systems. With the increasing awareness for safe drinking water and the growing consumption for oral care products like toothpaste and mouth floss would prove to be an adequate means of reaching greater sales in the market. There’s been improving hygiene consciousness leading to more oral care consumption. Moreover, there is a tendency to grow consumption of such products because they deal with oral health problems like tooth pain sensitivity as well as decay.
