Molecular Structure



Chlorphenesin is used for its antifungal properties and is also used as an antimycotic agent (anti-microbial properties), and thus is used as a preservative in various cosmetics. It is classified as an antifungal for topical use by the World Health Organization (WHO).

As a preservative, Chlorphenesin prevents various products from running into issues such as such as viscosity changes, pH changes, emulsion breakdown, visible microorganism growth, color changes and disagreeable odor formation. In addition to anti-fungal nail treatments, this ingredient is contained in products such as facial moisturizer, anti-aging treatment, sunscreen, foundation, eye cream, cleanser, mascara and concealer.
