It has bacteriostatic and antifungal activity, can effectively inhibit the growth of bacteria and fungi, and keep products fresh and stable. In cosmetics, chlorphenesin plays an antiseptic role, preventing the growth and spread of microorganisms, thereby extending the service life of cosmetics. This is important to protect consumer health, as some microorganisms may cause irritation or infection on the skin. Chlorphenesin is also commonly used in medical and pharmaceutical fields as a muscle relaxant. It relieves muscle pain and discomfort by blocking signals transmitted by nerves and reducing muscle spasm and tension. It is important to note that although chlorphenesin is widely used in cosmetics and skin care products, individual tolerance to it may vary. Therefore, when using products containing chlorphenesin, it is best to conduct a skin sensitivity test first to ensure there is no allergic reaction. Application 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.
