Isopropyl myristate (IPM) is the ester of isopropyl alcohol and myristic acid.


Isopropyl myristate is a polar emollient and is used in cosmetic and topical medicinal preparations where good absorption into the skin is desired. Isopropyl myristate is being studied as a skin enhancer. It is also used as a pesticide against head lice which works by dissolving the wax that covers the exoskeleton of head lice, killing them by dehydration.[2] It is used in the same way in flea and tick killing products for pets.

It is used to remove bacteria from the oral cavity as the non-aqueous component of the two-phase mouthwash product "Dentyl pH".

Isopropyl myristate is also used as a solvent in perfume materials, and in the removal process of prosthetic make-up.

Hydrolysis of the ester from isopropyl myristate can liberate the acid and the alcohol. The acid could be responsible for decreasing of the pH value of formulations.[3][4]
