Tin(II) fluoride Chemical Properties,Usage,Production

Chemical Properties

white crystals or powder

Chemical Properties

Stannous fluoride is a white crystalline solid with a bitter, salty taste.

Uses

Stannous fluoride (SnF2) is used as a toothpaste additive to help prevent tooth decay.

Uses

Tin(II) fluoride is used in the prevention of dental caries. It is an active ingredient in toothpastes.

Uses

Dental caries prophylactic.

Definition

ChEBI: Stannous fluoride is an inorganic fluoride salt.

General Description

White crystalline solid. Sinks and mixes with water.

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].

Hazard

Toxic by ingestion, strong irritant to skin and tissue.

Health Hazard

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

Flammability and Explosibility

Not classified

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.
