Chlorphenesin

What is Chlorphenesin?

Chlorphenesin is a synthetic organic compound classified as a chlorophenoxy alcohol, typically used in cosmetics like creams, lotions, serums, shampoos, and makeup. It serves as a broad-spectrum antimicrobial agent, targeting bacteria, yeasts, and molds that could spoil products or transfer to skin. By interfering with microbial cell processes, it maintains formula stability, prevents odor development, and supports shelf life in water-based formulations. This ingredient is valued for its compatibility with other cosmetic components and effectiveness across a range of pH levels. Cosmetic regulatory assessments confirm its role in product protection without compromising typical use safety. Its colorless, odorless nature makes it ideal for diverse personal care items, from daily skincare to hair products.
