General Description:
Menthyl Lactate is an ester of menthol and lactic acid, known for its mild, long-lasting cooling effect without the intense, sometimes irritating sensation associated with pure menthol. It appears as a white crystalline solid or powder and offers a refreshing sensory profile, making it an increasingly popular ingredient in personal care formulations. Menthyl Lactate is favored for its stability, pleasant minty aroma, and gentle action, and is widely available for bulk supply to support large-scale cosmetic production.
Uses in the Cosmetics Industry:
Menthyl Lactate is commonly used in:
Skin care products such as gels, creams, and after-sun lotions to provide a cooling and soothing sensation.
Shampoos, conditioners, and scalp treatments for a fresh, invigorating feel.
Lip balms and oral care products to impart a subtle, long-lasting minty taste and coolness.
Deodorants and foot care items to enhance freshness and user comfort.
Shaving products and post-shave balms to calm the skin and reduce irritation.
Its mild, delayed cooling effect and excellent compatibility with other ingredients make it ideal for both rinse-off and leave-on applications.
Side Effects & Hazards:
Menthyl Lactate is generally considered safe for cosmetic use and is well-tolerated by most skin types. It has a much lower irritation potential compared to menthol, making it suitable for sensitive skin areas and mucous membranes. However, high concentrations may still cause mild irritation in rare cases, especially around the eyes or on broken skin. It is not known to be toxic, carcinogenic, or mutagenic. During manufacturing, protective equipment such as gloves, goggles, and dust masks (if handling in powder form) is recommended to avoid inhalation or direct contact. The ingredient should be stored in a cool, dry, and well-ventilated area, in tightly sealed containers to prevent moisture absorption and maintain product stability.
