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.
 

As groundwater and surface water pollution increases, the need for water treatment solutions is growing. Fluorosilicic acid, a colorless and fuming liquid with a strong odor, is a by-product of making hydrogen fluoride and phosphoric acid. It is usually neutralized with limestone or milk of lime to make it harmless. Commercially, it is available as an aqueous solution in both pure and technical grades, with concentrations up to 70%. It is used in hardening cement and ceramics, water fluoridation, and wood preservation, as well as in textile processing, metal processing, electroplating, and oil well acidizing.
 

Fluorosilicic acid is also used in sterilization, commercial laundry, as a neutralizing agent, and in rust removal. The growing demand from the textile industry, especially for removing stains and rust from fabrics, is expected to boost the market. Factors like cost-effectiveness, high quality, environmental friendliness, easy availability of raw materials, and improved production facilities will drive market growth.

The 40% grade segment was valued at USD 233.6 million in 2024, and it is anticipated to expand 6.7% of CAGR during 2025-2034. Public drinking water is fluoridated with a 40% grade to maintain optimal fluorine levels, effectively preventing tooth decay. Esteemed organizations, including the U.S. Public Health Service, the American Dental Association, the American Academy of Pediatrics, and the WHO, advocate for community water fluoridation. Their endorsement is poised to bolster market growth. Additionally, evolving brand preferences and a burgeoning organized retail landscape are invigorating the textile industry, which is projected to capture a 40% market share.
 

The industry's growth is being fueled by a rising demand for oral care products, driven by an expanding geriatric population and a diverse range of available denture products. Additionally, stringent government regulations aimed at curbing water contamination, coupled with heightened government spending on water treatment, are key factors propelling the growth of the 40% grade fluorosilicic acid market. This 40% grade product finds extensive application as a cleaner and pH adjuster in the textile industry. Furthermore, rapid industrialization and a surge in fabric production are bolstering the growth of the textile industry during the forecast period.
 

Silicofluorides segment was valued at USD 107.5 million in 2024 and gained 7.1% CAGR from 2025 to 2034. Urban populations are on the rise, water pollution levels are escalating, and health awareness is growing. These factors, combined with stringent government regulations and a global uptick in water consumption, are set to boost the demand for water chemicals. Furthermore, heightened industrial activities and a growing emphasis on safe drinking water, driven by health concerns, are poised to bolster revenues in the fluorosilicic acid market.
 

The practice of water fluoridation, which involves adding industrial-grade fluoride chemicals to water to combat tooth decay, is gaining traction. This, coupled with a rising consumer preference for natural ingredients in oral care products like floss and mouthwash, is expected to fuel product demand in the near future. Additionally, as consumers increasingly prioritize preventing tooth decay and seek safe, effective ingredients to combat cavities across all age groups, these trends are likely to benefit the fluorosilicic acid industry during the forecast period.
 

According to U.S. public health officials, maintaining a controlled level of fluoride in community water supplies can effectively prevent dental caries while minimizing the risk of dental fluorosis. WHO data highlights that dental caries in permanent teeth ranks as the most prevalent health issue worldwide. Furthermore, the Australian Department of Health asserts that water fluoridation is a safe and effective measure for enhancing oral health across all age groups.
 

The U.S. fluorosilicic acid market was valued at USD 170.5 million in 2024 and expected to grow at a 7.2% CAGR. The U.S. government requires municipal corporations to add fluoridating agents to public drinking water. The American Dental Health Service Association supports water fluoridation as a key public health measure to prevent dental caries and recommends extending its benefits to all communal water systems. Growing awareness of safe drinking water and the rising demand for oral care products like toothpaste and mouth floss are expected to boost sales in the fluorosilicic acid industry. As more consumers focus on oral hygiene, sales of oral care products are increasing. Additionally, concerns about oral health issues, such as tooth pain, sensitivity, and decay, are driving up demand for these products.
