Description of 5-Methylcyclohexanol
5-Methylcyclohexanol, 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.
Refined OLE contains approximately 64% PMD (a mixture of the cis and trans isomers of 5-Methylcyclohexanol). 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. It is also registered with Canada’s Pest Management Regulatory Agency under the generic name “PMD and related oil of lemon eucalyptus compounds”. It is the only natural active ingredient that is permitted to be used an insect repellent in the United States and Europe.; PMD can be synthetically manufactured from materials derived from natural sources. This 2011 study also shows that C. citriodora oil contains only 1-2% PMD and is therefore different from OLE as registered with the EPA which has a minimum 64% PMD. A 2006 study showed that PMD is as effective as DEET when used in like quantities.

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 5-Methylcyclohexanol ?
- The official answer：Menthol, also known as p-menthane-3,8-diol, or PMD for short, is listed in the National Cosmetic Ingredients Catalogue (2016) and GB2760 Food Additives Catalogue for cosmetic and food coolant use.
What’s the application of p-Menthane-3,8-diol?
- Mendiola is an insect repellent, insecticide composition characterized by: an insect repellent, insecticide composition comprising (a) lemongrass oil (citronella oil); (b) medial; (c) vanillin; and (d) a delivery medium; wherein: the mass ratio of p-menthyl-3,8 diol and lemongrass oil (citronella oil) is 10 to 2:1. Advantages of the invention: is based on known natural ingredients to alleviate the limitations of current products. Uses two or more insect repellent materials synergistically to produce a product with added benefits and superior efficacy in a unique formulation. This new combination was found to be effective in repelling mosquitoes with a strong insect repellent effect. Formulations containing lemongrass oil (citronella oil) and model have been shown to be effective against malaria mosquitoes, mosquito-borne malaria mosquitoes, and Aedes aegypti, which transmits dengue and yellow fever. UsesMenthanediol is an alcoholic organic compound that is used as a pharmaceutical ingredient.
