2-Methyl-4-isothiazolin-3-one (MI) is an isothiazolinone-derived biocide used for controlling microbial growth in industrial and household products, often in a mixture with 5-chloro-2-methyl-3-isothiazolone (MCI). MI is active against Gram-positive and Gram-negative bacteria, fungi, and yeast with MIC values of 0.0045, 0.0015, >0.01, and 0.0065% (w/w) for S. aureus, P. aeruginosa, A. niger, and C. albicans, respectively, when used alone. MIC values are 7 to 200-fold lower when MI is used in combination with MCI. MI decreases neurite outgrowth of rat cortical neurons when used at concentrations of 0.1-3 μM and inhibits Src family kinases in cell-free assays. MI, alone and as a mixture with MCI, can elicit contact sensitization.??? ??
2-Methyl-4-isothiazolin-3-one (MIT) is a colorless,clear liquid with amild odor that is completely soluble in water; mostly soluble in acetonitrile, methanol, and hexane; and slightly soluble in xylene. MIT is a heterocyclic organic compound used as a preservative in cosmetics and personal care products in concentrations up to 0.01%.??
Methylisothiazolinone is a preservative compound widely used in cosmetics. It is a contact allergen and sensitiser. Methylisothiazolinone has recently been identified as a neurotoxin that can damage nerve endings with repeated exposure.??
ChEBI: Methylisothiazolinone is a 1,2-thazole that is 4-isothiazolin-3-one bearing a methyl group on the nitrogen atom. It is a powerful biocide and preservative and is the minor active ingredient in the commercial product Kathon(TM). It has a role as an antifouling biocide, an antimicrobial agent and an antifungal agent.?? ??
2-Methyl-4-isothiazolin-3-one (MIT)is prepared by cyclization of cis-N-methyl-3-thiocyanoacrylamide: NCSCH=CHC(O)NHCH3?SCH=CHC(O)NCH3+HCN???
2-Methyl-4-isothiazolin-3-one(MIT)is allergenic and cytotoxic, and this has led to some concern over its use.A report released by the European Scientific Committee on Cosmetic Products and Non-food Products Intended for Consumers (SCCNFP) in 2003 also concluded that insufficient information was available to allow for an adequate risk assessment analysis of MIT.?? ?? ??
MI is generally associated with MCI, in Kathon? CG, MCI/MI, and Euxyl? K 100. This preservative is currently used in water-based products such as cosmetics, paints, and glues. Skin contact with concentrated solution can cause severe irritant dermatitis.???
Early on, dermatitis may occur only on part of the exposed skin. Common patterns include: hand dermatitis，perianal dermatitis, perivulval dermatitis, napkin dermatitis, facial dermatitis, eyelid swelling, and scalp dermatitis. Later, more extensive and severe whole-body contact dermatitis may occur in very sensitive people.2-??-4-??????-3-? ?? ?? ? ???
