Usage

Description

Tin(II) fluoride, also known as stannous fluoride (SnF2), is a white crystalline solid or powder with a bitter, salty taste. It is a chemical compound that has found significant applications in the dental industry due to its beneficial properties.

Uses

Used in Dental Industry:
Tin(II) fluoride is used as a toothpaste additive for the prevention of dental caries. It serves as an active ingredient in toothpastes, helping to protect teeth from decay and maintain oral health. Tin(II) fluoride's effectiveness in combating tooth decay is attributed to its ability to enhance the tooth's resistance to acid attacks and promote the remineralization of enamel.

Air & Water Reactions

Water soluble.

Reactivity Profile

Tin(II) fluoride, a strong reducing agent, is incompatible with oxidizers. Avoid contact with acids - HF fumes may be produced [USCG, 1999].

Health Hazard

EYES: Severe irritation - corrosive, irreversible. SKIN: Corrosive on abraded skin, no effect on intact skin.

Flammability and Explosibility

Notclassified

Safety Profile

Poison by ingestion and intraperitoneal routes. Questionable carcinogen. Mutation data reported. When heated to decomposition it emits toxic fumes of F-. See also TIN COMPOUNDS.

Potential Exposure

Stannous fluoride is used in dental caries (tooth decay); as an ingredient of cavity-preventing toothpastes.

Shipping

UN2811 Toxic solids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required. UN2923 Corrosive solids, toxic, n.o.s., Hazard class: 8; Labels: 8-Corrosive material, 6.1Poisonous material, Technical Name Required

Incompatibilities

A strong reducing agent. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Reacts with acids, forming hydrogen fluoride fumes. Reacts violently with chlorine and metal nitrates. Reacts with metals releasing flammable hydrogen gas.
