Description

trans-p-Menthane-3,8-Diol is a naturally occurring monoterpene diol, also known as PMD, valued for its potent insect-repellent properties. This compound is a key active ingredient in botanical insect repellents, offering a plant-based alternative to synthetic agents like DEET. It is primarily sought by manufacturers in the personal care, insecticide, and flavor & fragrance industries for formulating effective and consumer-friendly repellent products.

Application

• Primary Active in Insect Repellents: Formulated into sprays, lotions, and wipes as the main repellent agent against mosquitoes and other biting insects.
• Personal Care Products: Incorporated into soaps, creams, and after-sun lotions to provide added protection.
• Household Insecticide Formulations: Used in candles, diffusers, and spatial repellents for area protection.
• Flavor and Fragrance Industry: Serves as a building block or intermediate for synthesizing specific minty or fresh aroma chemicals.
• Botanical Extracts and Blends: Used as a standardized component in natural extract blends marketed for repellency.
• Veterinary and Pet Care Products: Formulated into shampoos, sprays, and spot-on treatments for animal use.
• Agricultural Adjuvants: Potential use in crop protection products as a repellent for certain pests.
• Research and Development: Used in academic and industrial labs for studying structure-activity relationships of terpenes and developing new bioactive compounds.
