Product Description
Preventol CMK, also known as p-Chloro-m-cresol (PCMC, CAS No. 59-50-7), is a highly effective broad-spectrum antimicrobial preservative. It is widely used in industrial and personal care formulations to inhibit the growth of bacteria, fungi, and yeasts. As a phenolic-type biocide, Preventol CMK provides strong and long-lasting protection even at low concentrations, making it ideal for both water-based and solvent-based systems.
The product appears as an off-white crystalline solid with a characteristic phenolic odor, showing excellent chemical stability and compatibility with a wide range of surfactants and emulsifiers. It can be used alone or in combination with other preservatives to achieve synergistic effects. Preventol CMK is valued for its efficacy in harsh environments, maintaining preservation in formulations with high temperature or alkaline conditions.
