Overview
Sodium fluoride is an important ionic compound and a key fluoride product. It is widely used across multiple industries due to its unique chemical properties and high purity.

Applications

• Dental care: Used as an active ingredient in toothpaste, mouthwashes, and dental treatments for caries prevention.

• Food fortification: Added as a fluoride supplement in food products and drinking water to support dental health.

• Pharmaceutical intermediates: Used in the synthesis of various pharmaceutical compounds and fluorine-containing drugs.

• Metallurgy: Employed as a flux in aluminum and steel production.

• Chemical industry: Raw material for the production of other fluoride compounds and specialized chemicals.

• Glass and ceramics: Used in the manufacturing of specialty glasses and glazes.

Recommended Usage
In toothpaste and oral care products, typical concentrations range from 0.1% to 0.25% as fluoride ion. For water fluoridation, levels are adjusted to approximately 0.7–1.2 mg/L depending on local regulations.

Handling and Storage

• Store in a cool, dry, well-ventilated area, away from acids (especially mineral acids).

• Keep containers tightly sealed to prevent moisture absorption and contamination.

• Use appropriate personal protective equipment (gloves, safety goggles, dust mask) when handling.

Safety
Sodium fluoride is toxic in high concentrations. Avoid inhalation of dust and contact with skin and eyes. In case of contact, rinse thoroughly with water. For detailed safety information, refer to the Safety Data Sheet (SDS).
