KATHON® CG Preservative
KATHON™ CG is a highly effective, broad-spectrum isothiazolinone preservative designed primarily for rinse-off personal care applications. It contains a synergistic blend of methylchloroisothiazolinone (CMIT) and methylisothiazolinone (MIT) in an aqueous solution with stabilizing salts, delivering strong antimicrobial protection against bacteria, yeast, and molds at very low use levels. The formulation is water-based, easy to incorporate, and compatible across a wide range of cosmetic ingredients while maintaining a favorable environmental profile due to rapid degradation and non-bioaccumulation.
