Description

Isothiazolinones are a class of broad spectrum biocides used as preservatives in shampoos and many other household and industrial products.

Uses

Isothiazolinones are used in cosmetics and shampoos as a biocide to kill fungus and bacteria. Unlike the preservatives DMDM hydantoin and imidazolidinyl urea also commonly used in these products, isothiazolinones do not release formaldehyde, to which some people are sensitive.

Some people are sensitive to isothiazolinones.
