p-Menthane-3,8-diol CAS#42822-86-6

Product Application Of p‑Menthane‑3,8‑diol CAS#42822‑86‑6

p‑Menthane‑3,8‑diol, also called PMD or menthoglycol, is a well‑known bio‑based active repellent ingredient. It delivers mint‑menthol aroma and provides cooling sensation on skin. It can be formulated into sprays and lotions, applied on human skin and fabrics to repel mosquitoes, biting flies and gnats.

Production Preparation Method

p‑Menthane‑3,8‑diol can be obtained by two mainstream routes. One is semi‑synthesis: citronellal from lemon eucalyptus oil undergoes acid‑catalyzed cyclization reaction. The other is physical extraction and purification from refined lemon eucalyptus oil. Crude material is further recrystallized and filtered to get finished crystalline PMD with controlled isomer ratio of cis‑trans components.

Detailed Application Scenarios

Insect‑Repellent Personal‑care Formulations

It serves as DEET‑free bio‑active ingredient for outdoor repellent products. Suitable for making repellent sprays, skin lotions, and fabric‑applied repellents, effective against mosquitoes, biting flies and gnats. It brings mild cooling‑menthol feeling for skin‑contact products.

Cosmetic & Daily‑chemical Raw Material

Used in outdoor‑oriented personal care formulas. Its mint‑herbal note can also be used for fragrance adjustment in some topical care products.

Biocide Raw Material for Registration

PMD‑rich botanical oil has passed notification under EU BPR regulation. It can be supplied as technical material for customers to complete local biocidal product registration in EU, UK and Canada markets.

Customers use our high‑purity p‑Menthane‑3,8‑diol for completing local biocidal‑product registration dossier in European markets. Stable cis‑trans isomer ratio helps registration progress.

FAQ Frequently Asked Questions

Q1: What is the difference between PMD and lemon eucalyptus essential oil?

A: PMD (p‑Menthane‑3,8‑diol) is the purified active repellent component. Raw lemon eucalyptus essential oil only contains low‑level PMD and cannot be directly used as repellent technical material.

Q2: What is the typical purity of commercial‑grade PMD?

A: Standard purity ≥98%. Custom isomer‑ratio grades can be produced upon request.

Q3: What is shelf‑life for storage?

A: 24 months under original sealed, cool and dry storage environment. Seal tightly once opened to prevent moisture absorption.

Q4: Can PMD be used directly on human skin?

A: PMD technical material cannot be directly applied to skin. It needs to be diluted and formulated into finished repellent products according to local regulatory standards.
