MSDS Information

Methylchloroisothiazolinone/methylisothiazolinone mixture (MCIT/MIT) Usage And Synthesis

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. 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. MCIT/MIT can elicit contact sensitization. Formulations containing MCIT/MIT have been used for controlling microbial growth in industrial and household products.
Uses	Antimicrobial preservative in cosmetics, hygeine products, paints, emulsions, cutting oils, paper coatings, and water storage and cooling units.
Hazard	A poison by ingestion.
Contact allergens	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.
