Description: Isothiazolinone is a heterocyclic chemical compound related to isothiazole. Isothiazolinone is an antimicrobial preservative that is often used to control fungi, bacteria, and algae. Since water-containing solutions are the breeding grounds for bacteria, isothiazolinone can easily be used in such solutions.

Applications: Although isothiazolinones have no direct applications, their derivatives such as 5-chloro-2-methyl-4-isothiazolin-3-on and 2-methyl-4-isothiazolin-3 which are used together as preservatives in commercial households and cosmetics products, for instance, cleaners, shampoos, and washing materials. 

Notably, various products that use isothiazolinones are in the market, including shampoo, hand sanitizer, and lotions. Isothiazolinones is used in these products as an inhibitor of microbial activity that could lead to the product spoiling before the expected expiration date.

Description

Methylchloro-isothiazolinone (MCI) is contained, along with methylisothiazolinone (MI), in Kathon cosmetic grade (CG) and MCI/MI. It is irritant and sensitizer.

Methylchloroisothiazolinone, also referred to as MCI, is a preservative with antibacterial and antifungal effects within the group of isothiazolinones. These compounds have an active sulphur moiety that is able to oxidize thiol-containing residues, thereby effectively killing most aerobic and anaerobic bacteria.[1] Methylchloroisothiazolinone is effective against gram-positive and gram-negative bacteria, yeast, and fungi.

Methylchloroisothiazolinone is found in many water-based personal care products and cosmetics.[2] Methylchloroisothiazolinone was first used in cosmetics in the 1970s. It is also used in glue production, detergents, paints, fuels, and other industrial processes. Methylchloroisothiazolinone is known by the registered tradename Kathon CG when used in combination with methylisothiazolinone.[3]

Methylchloroisothiazolinone may be used in combination with other preservatives including ethylparaben, benzalkonium chloride, and bronopol.

5-Chloro-2-methyl-4-isothiazolin-3-one

Chloromethylisothiazolinone is a 1,2-thiazole that is 4-isothiazolin-3-one bearing a methyl group on the nitrogen atom and a chlorine at C-5. 

It is a powerful biocide and preservative and is the major active ingredient in the commercial product Kathon(TM). 

It has a role as an antimicrobial agent, a xenobiotic and an environmental contaminant. 

It is a member of 1,2-thiazoles and an organochlorine compound. It derives from a methylisothiazolinone.

Methylchloroisothiazolinone (MCI) is an isothiazolinone commonly used as a preservative with antibacterial and antifungal properties.

It is found within many commercially available cosmetics, lotions, and makeup removers. 

It is also a known dermatological sensitizer and allergen; some of its side effects include flaky or scaly skin, breakouts, redness or itchiness, and moderate to severe swelling in the eye area. 

The American Contact Dermatitis Society named Methylchloroisothiazolinone the Contact Allergen of the Year for 2013. 

Sensitivity to Methylchloroisothiazolinone may be identified with a clinical patch test.

Safety

Methylchloroisothiazolinone can cause allergic reactions in some people.[4] The first publication of the preservative as a contact allergen was in 1988.[5] Cases of photoaggravated allergic contact dermatitis, i.e. worsening of skin lesions after sun exposure, have also been reported.[4]

In pure form or in high concentrations, methylchloroisothiazolinone is a skin and membrane irritant and causes chemical burns. In the United States, maximum authorized concentrations are 15 ppm in rinse-offs (of a mixture in the ratio 3:1 of 5-chloro-2-methylisothiazol 3(2H)-one and 2-methylisothiazol-3 (2H)-one).[6] In Canada, methylchloroisothiazolinone may only be used in rinse-off products in combination with methylisothiazolinone, the total concentration of the combination may not exceed 15 ppm.[7]

As of 2008, the International Agency for Research on Cancer (IARC), did not list methylchloroisothiazolinone as a known, probable, or possible human carcinogen,[8] nor have in vivo tests found evidence of carcinogenic activity
