• Description: Selenium sulfide is a selenium salt that exists as a yellow-orange to bright-orange tablet or powder at room temperature. It is insoluble in water or ether and soluble in carbon disulphide. It is incompatible with acids, metals, strong oxidising agents, chromium trioxide, potassium bromate, silver oxide, and ammonia. Selenium sulfide is used as an active ingredient in anti-dandruff shampoos and as a constituent of fungicides. Selenium sulfide is an anti-fungal agent as well as a cytostatic agent, slowing the growth of hyperproliferative cells in seborrhoea. Selenium sulfide is the active ingredient often used in shampoos for the treatment of dandruff, seborrheic dermatitis, and tinea capitis, a fungal infection that is primarily a disease of preadolescent children. Selenium sulfide is highly active in inhibiting the growth of P. ovale. It is also a proven cytostatic agent, slowing the growth of both hyperproliferative and normal cells in dandruff and seborrheic dermatitis. A 0.6% micronised form of Selenium sulfide is also safe and effective for dandruff. Selenium sulfide is not present in foods and is a very different chemical from the organic and inorganic selenium compounds found in foods and in the environment.
• Uses: Selenium sulfide (SeS2) is used for some medicines, as an additive for medicated shampoos to control dandruff and scalp itching, and in treatment products for acne and eczema. For treatment of tinea versicolor, tinea capitis, dandruff and seborrheic dermatitis of the scalp.
• Clinical Use: Selenium sulfide is a cytostatic and sporicidal agent available without prescription in a variety of shampoos and lotions for treatment of scalp seborrheic dermatitis.

Technology Process of Selenium sulfide

There total 8 articles about Selenium sulfide which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield: 97.0%

mercury sulfide + selenium dibromide (22987-45-7) → selenium sulphide (7446-34-6)

Guidance literature:

with 100% selenium bromide excess after 12 h;

Reference yield:

hydrogen sulfide (7783-06-4) + selenious acid (7783-00-8) → selenium sulphide (7446-34-6)

Guidance literature:

In not given; byproducts: S; ppt. of SeS and S;;

Reference yield:

potassium selenite + hydrogen sulfide (7783-06-4) → selenium sulphide (7446-34-6)

Guidance literature:

In water; passing of gaseous, ice-cooled H2S through a very dild., neutral aq. soln. of K2SeO3 at 0 - 5 °C;; product slightly decomposed;;
