Usage

Indications

Selenium sulfide suspension (Selsun) is a mixture of selenium monosulfide and a suspension of solid selenium and amorphous sulfur. Selenium acts by inhibiting cellular proliferation, kills yeast organisms, and has high substantivity. Little or no toxicity has been observed when applied directly to normal skin or hair, but these products should not be used on inflamed or exudative skin, where absorption may be increased. They are used in the control of seborrheic dermatitis, dandruff, and tinea versicolor.

Air & Water Reactions

Slightly water soluble.

Reactivity Profile

Selenium sulfide may react vigorously with acids to release hydrogen sulfide gas.. May react with oxidizing agents, including inorganic oxoacids, organic peroxides and epoxides.

Fire Hazard

Combustible material: may burn but does not ignite readily. When heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form.

Flammability and Explosibility

Notclassified

Safety Profile

Poison by ingestion. Used in shampoos. When heated to decomposition it emits very toxic fumes of SO, and Se. See also SELENIUM COMPOUNDS and SULFIDES.
