Name Selenium Sulfide Molecular Formula HSSe MW 112.03300 Molecular Weight 837.047 CAS :7488-56-4 Appearance yellow powder
Selenium Sulfide is an inorganic compound with the approximate formula SeS2. Both sulfur and selenium catenate (form chains and rings) readily, and mixtures of selenium and sulfur likewise give rise to numerous "alloys". This compound is not an analogue of sulfur dioxide. Selenium disulfide has a composition that approximates to SeS2 and is sometimes called selenium sulfide.
Function 1. Wet hair thoroughly, apply shampoo, generously lather, rinse thoroughly. 2. Repeat if necessary.
