Selenium disulfide, also known as selenium sulfide, is a chemical compound and medication used to treat seborrheic dermatitis, dandruff, and pityriasis versicolor. [1] [2] It is applied to the affected area as a lotion or shampoo. [3] Symptoms frequently return if treatment is stopped. [4]
Selenium disulfide consists of 8-membered rings. It has an approximate composition of SeS 2, with individual rings varying in composition, such as Se 4 S 4 and Se 2 S 6. Selenium disulfide has been used in shampoo as an antidandruff agent, an inhibitor in polymer chemistry, a glass dye, and a reducing agent in fireworks. [24]

[1] [2] [3] Selenium belongs with oxygen and sulfur to the group 16 elements or chalcogens, and similarities in chemistry are to be expected. Organoselenium compounds are found at trace levels in ambient waters, soils and sediments. [4] Selenium can exist with oxidation state −2, +2, +4, +6. Se(II) is the dominant form in organoselenium ...
Simplest is the material selenium sulfide, which has medicinal properties. It adopt the diverse structures of elemental sulfur but with some S atoms replaced by Se. Other inorganic selenide sulfide compounds occur as minerals and as pigments. One example is antimony selenosulfide.
A selenium version of this ring type has been made, one notable example has been named Woollins' reagent and is Ph 2 P 2 Se 4, this is made by the reaction of (PhP) 5 with selenium metal. The solubility of this compound is very low but the group of Prof John Derek Woollins have published some reactions of this compound.
