Description

p-Menthane-3,8-Diol (CAS NO 91739-72-9) is a naturally derived, bicyclic monoterpene diol valued for its unique sensory and functional properties. This compound serves as a key ingredient in formulations requiring natural cooling and refreshing effects. It is primarily sought after by manufacturers in the personal care, cosmetics, and flavor & fragrance industries for its ability to enhance product performance and consumer appeal.

Application

• Cooling Agent in Personal Care: A primary ingredient in lip balms, aftershaves, body lotions, and skincare products to impart a long-lasting, natural cooling sensation without menthol's pungency.
• Flavor & Fragrance Modifier: Used in chewing gums, candies, oral care products (toothpaste, mouthwash), and perfumery to provide a fresh, cooling note and enhance overall sensory profiles.
• Topical Analgesic Formulations: Incorporated into gels, creams, and patches for its soothing and mild analgesic properties to relieve minor muscle aches and skin irritation.
• Functional Additive in Cosmetics: Acts as a sensate and skin-feel enhancer in high-end cosmetic serums, masks, and toners.
• Insect Repellent Synergist: Used in combination with other active ingredients in natural insect repellent formulations to improve efficacy and user comfort.
