O-Cymen-5-Ol
What is O-Cymen-5-Ol?
O-Cymen-5-ol, chemically 4-isopropyl-3-methylphenol, is a synthetic alkylphenol compound developed for personal care applications. It appears as a white to pale yellow crystalline solid with a characteristic odor. Primarily used in rinse-off and leave-on cosmetics like creams, lotions, shampoos, and oral rinses, it serves in the preservation category. Its mechanism involves disrupting microbial cell membranes, interfering with enzyme activity, and halting reproduction of bacteria, yeasts, and molds. This broad-spectrum antimicrobial action occurs at low levels, typically integrated into water-based or emulsion formulas to prevent spoilage without impacting texture or fragrance significantly. Regulatory bodies like the EU permit its use under specific conditions, reflecting evaluations of its stability and compatibility in diverse formulations.
