Chlorphenesin is a classic and effective preservative widely used in cosmetic and personal care formulations. It is odorless and non-irritating, ensuring product safety and user comfort. Chlorphenesin is compatible with many other preservatives, such as potassium sorbate, sodium benzoate, and methylisothiazolinone, enhancing formulation flexibility. It has been proven effective against a wide range of microbes, particularly fungi, providing reliable preservation for cosmetic products.

This ingredient is supplied as a white to almost white powder and is soluble in both alcohol and water, making it suitable for incorporation into creams, lotions, serums, and other alcohol- or water-based formulations. With a recommended usage of 0.1–0.3%, it ensures effective preservation while maintaining formulation stability.
