Description
Opaque white crystals; Minty, herbaceous, Eucalyptus-like aroma
P-menthane-3,8-diol is a p-menthane monoterpenoid in which p-menthane carries hydroxy groups at C-3 and C-8. It derives from a hydride of a p-menthane.
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 p-Menthane-3,8-diol, and the exact composition is rarely specified and is commonly assumed to be a complex mixture.Refined OLE contains approximately 64% p-Menthane-3,8-diol (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 "p-Menthane-3,8-diol 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 "p-Menthane-3,8-diol and related oil of lemon eucalyptus compounds".
p-Menthane-3,8-diol has a faint minty, herbaceous, eucalyptus-like odor. The cooling power is reported to be approxi mately 9.5 times that of (-)-menthol.

p-Menthane-3,8-diol Use and Manufacturing
p-Menthane-3, 8-diol, also known as para-menthane-3, 8-diol and PMD, is an active ingredient used in insect repellents. p-Menthane-3, 8-diol smells similar to menthol and acts as a coolant.P-menthane-3,8-diol is used to make products that are applied to human skin and clothing for the purpose of repelling insects, such as mosquitoes, biting flies and gnats. P-menthane-3,8-diol can be used in two types of consumer pesticide products: a spray and a lotion.
2-Hydroxy-α,α,4-trimethylcyclohexanemethanol is used in protection measures in the prevention of tick-born diseases. Acaricide.
