Description

L-Menthyl Lactate is a high-purity chiral ester derived from natural L-menthol and lactic acid, valued for its unique cooling and refreshing properties. This compound is a key ingredient in advanced personal care and flavor formulations, offering a clean, non-irritating cooling sensation without the pungency of menthol. It is essential for manufacturers in the cosmetics, personal care, and food industries seeking to enhance product sensory profiles with a natural-feel cooling agent. Its stability and compatibility make it a versatile choice for a wide range of consumer products.

Application

• Cooling Agent in Personal Care: A primary ingredient in lip balms, shaving creams, after-sun lotions, and body washes to impart a prolonged, soothing cooling effect.
• Flavor & Fragrance Modifier: Used in chewing gums, confectionery, oral care products (toothpaste, mouthwash), and alcoholic beverages to provide a refreshing minty-cool note.
• Topical Analgesic Formulations: Incorporated into creams, gels, and patches for muscle pain relief, offering a cooling sensation that distracts from minor aches.
• Cosmetic & Skincare Products: Enhances the sensorial appeal of facial toners, moisturizers, and masks with a refreshing feel upon application.
• Pharmaceutical Preparations: Utilized as a flavoring and cooling agent in certain OTC medicinal syrups and lozenges.
• Industrial Applications: Serves as a chiral intermediate or solvent in specialized organic synthesis for the pharmaceutical and agrochemical sectors.
