ISCA GUARD CMI

About ISCA GUARD CMI

Iscaguard CMI is a highly effective broad-spectrum preservative system containing a blend of Methylchloroisothiazolinone (MCI) and Methylisothiazolinone (MI) in a 3:1 ratio, supplied as a stabilized aqueous solution. It is designed to provide excellent protection against bacteria, yeasts, and molds at very low use levels. Iscaguard CMI is particularly effective in water-based and surfactant-based formulations where microbial contamination can compromise product safety and shelf life. The preservative is widely used in shampoos, shower gels, liquid soaps, bath foams, and other rinse-off personal care products. It offers rapid antimicrobial activity across a broad spectrum of microorganisms and remains effective over a wide pH range. Due to its high efficacy, only small amounts are required to achieve reliable preservation. However, because isothiazolinones are known sensitizers, regulatory authorities strictly control their use in cosmetic products, especially leave-on applications. Iscaguard CMI is valued for its cost-effectiveness, ease of incorporation, and proven preservation performance in rinse-off formulations.
