Background
Cl+Me-isothiazolinone
(MCI/MI) is a combination of 2-methyl-4-isothiazolin-3-one
and 5-Chloro-2-methyl-4-isothiazolin-3-one. These isothiazolinones are
frequently combined as a broad spectrum preservative. A recent Danish study (Nielsen) found
MCI/MI registered in 523 products. The most frequently
registered products were paints, hair shampoos, skin care products, and
cleaning agents. The typical concentration was below 0.0035% (35 ppm).
The isothiazolinone preservatives include: 2-n-Octyl-4-isothiazolin-3-one,
1,2-Benzisothiazolin-3-one, 2-methyl-4-isothiazolin-3-one, and 5-Chloro-2-methyl-4-isothiazolin-3-one.
