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 essential for formulators seeking a natural, long-lasting cooling sensation without the sharpness or irritation associated with some synthetic agents. It is primarily used by manufacturers in the flavor and fragrance, personal care, and pharmaceutical industries to enhance product profiles and sensory experiences.

Application

• Flavor & Fragrance Industry: As a key cooling agent in chewing gums, confectionery, oral care products (toothpaste, mouthwash), and mentholated tobacco.
• Personal Care & Cosmetics: Incorporated into skincare products (creams, lotions), aftershaves, and deodorants to provide a sustained, pleasant cooling effect.
• Pharmaceuticals: Used in topical analgesics, anti-itch creams, and throat lozenges for its soothing and mild anesthetic properties.
• Advanced Cooling Blends: Serves as a synergistic component in custom cooling blends for technical applications requiring controlled release and stability.
