Overview of Methylchloroisothiazolinone

Methylchloroisothiazolinone (MCI) is a highly effective, broad-spectrum biocide and preservative widely used in personal care and home care formulations to protect products against bacterial, fungal, and yeast contamination. It typically appears as a clear to pale yellow liquid and is known for its strong antimicrobial efficacy at very low use levels.

In personal care applications, Methylchloroisothiazolinone is used primarily in rinse-off products such as shampoos, conditioners, liquid soaps, body washes, and hair care formulations, where microbial control is essential to maintain product safety and shelf life. It is often used in combination with Methylisothiazolinone (MI) and works well alongside preservatives such as Phenoxyethanol, Sodium Hydroxymethyl Glycinate, and Dehydroacetic Acid in controlled preservation systems.

In home care products, Methylchloroisothiazolinone is widely used in household cleaners, detergents, fabric care products, surface disinfectants, and industrial cleaning formulations, where robust antimicrobial protection is required. Its effectiveness over a wide pH range makes it suitable for diverse cleaning systems.
