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.
