Selenium disulfide

Selenium disulfide is an inorganic compound often used in medicinal applications, particularly in the treatment of seborrhoeic dermatitis and dandruff. It is a bright orange solid that is insoluble in water but soluble in carbon disulfide.

Chemical Properties

Selenium disulfide consists of 8-membered rings, similar to its lighter congener sulfur. It is a bright orange solid that is insoluble in water but soluble in carbon disulfide. It is a component of anti-dandruff shampoos, which work by reducing the scalp oil (sebum) production.

Medical Uses

Selenium disulfide is used in medicinal shampoos to treat seborrhoeic dermatitis and dandruff. It works by slowing the growth of yeast that causes these conditions. It is also used to treat tinea versicolor, a fungal infection of the skin.
