Description of p-Menthane-3,8-diol

p-Menthane-3,8-diol, also known as para-menthane-3,8-diol, PMD, or menthoglycol, is an active ingredient used in insect repellents. It smells similar to menthol and has a cooling feel. There are eight possible isomers of PMD, and the exact composition is rarely specified and is commonly assumed to be a complex mixture.
PMD is found in small quantities in the essential oil from the leaves of Corymbia citriodora, formerly known as Eucalyptus citriodora. This tree is native to Australia, but is now cultivated in many warm places around the world.
C. citriodora oil, when refined to increase its PMD content for use in insect repellents, is known in the United States as oil of lemon eucalyptus (OLE) or by the tradename Citriodiol. Some commercial PMD products are not made from C. citriodora oil, but rather from synthetic citronellal.

What is p-Menthane-3,8-diol?

     With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is p-Menthane-3,8-diol which has developed particularly rapidly in recent years. Do you know about p-Menthane-3,8-diol?

  • The official answer: Menthol, also known as p-menthane-3,8-diol, or PMD for short, is included in the National Catalogue of Cosmetic Ingredients (2016) and the GB2760 Food Additive Catalogue for cosmetic and food coolant uses.
  • Refined OLE contains approximately 64% PMD (a mixture of the cis and trans isomers of p-menthane-3,8-diol). OLE has been notified under the European Biocidal Products Directive (BPD) 98/8/EC (now BPR Regulation (EU) No. 528/212) under its generic name “PMD rich botanic oil” and is currently proceeding through the registration process with the Health and Safety Executive in the UK.

What’s the application of p-Menthane-3,8-diol?

Mengediol is an insect repellent, insecticidal composition characterized by: an insect repellent, insecticidal composition comprising (a) lemongrass oil (citronella oil); (b) Mengediol; (c) vanillin; and (d) a delivery medium; wherein: the mass ratio of p-menthyl-3,8 diol to lemongrass oil (citronella oil) is 10 to 2:1. Advantages of the present invention: is based on known natural ingredients to alleviate the limitations of currently produced Chemicalbook products. Uses two or more insect repellent materials in synergy to produce a product with added benefits and superior efficacy in a unique formulation. This new combination has been found to be effective in repelling mosquitoes and has a strong insect repellent effect.
