Kathon® CG (CG = cosmetic grade) is a 3:1 mixture of CMI
and MI, at a 1.5% concentration. It is used for cosmetics and
toiletries, metalworking fluids or paints, in which it can be
added only periodically or in color film developers. Kathon®
886 MW (MW = metalworking fluids) is a mixture CMI/MI
mixture at a 13.9% concentration, mainly contained in metalworking
fluids. Kathon® FP 1.5 contains MCI/MI at 1.5%
concentration in propylene glycol. Kathon® LX (LX = LateX)
contains MCI/MI at a tenfold concentration of Kathon® CG.
Kathon® WT (WT = water treatment) is a MCI/MI mixture
used in the paper industry. Parmetol® K40, Parmethol® DF
12 and Parmetol® DF 35, Parmetol® A 23, Parmetol® K50,
and Parmetol® DF 18 are other brand names of MCI/MI. | [InChIKey]

A poison by ingestion. | [Description]
Kathon 886 metalwork fluid is a mixture of the two
isothiazoliones contained in Kathon CG, at a 13.9%
concentration. It is mainly contained in metalwork
fluids. As an active component of Aigezid Ⅱ and
contained in a water bath used for phtotographic
development, it caused contact dermatitis in a photograph
developer. | [Description]
Methylchloroisothiazolinone/methylisothiazolinone mixture (MCIT/MIT) is a mixture of isothiazolinone-derived biocides.1,2 It is effective against Gram-positive and Gram-negative bacteria with MIC values of 0.0002, 0.0002, 0.00005, and 0.00005% (w/w) for S. aureus, P. aeruginosa, A. niger, and C. albicans, respectively.2 MCIT/MIT can elicit contact sensitization.3 Formulations containing MCIT/MIT have been used for controlling microbial growth in industrial and household products. |
