Pyrithione zinc is a that not many people know about. I personally didn’t find out it existed until I looked at my shampoo bottle and saw it in the ingredients section. It is used in shampoo mostly since it has properties that can help treat seborrheic dermatitis or dandruff for short. Its chemical formula is C10H8N2O2S2Zn and has a molar mass of 317.70 g/mol. Pyrithione zinc has ten carbon, eight hydrogens, two nitrogen, 2 sulfur, and 1 zinc atoms. The boiling point of pyrithione zinc is 464 degrees Fahrenheit. The appearance of pyrithione zinc is actually nothing since it does not have color. It stays relevant in our lives since the properties of pyrithione zinc can help prevent and treat dandruff.
