Isopropyl myristate (IPM) is the ester of isopropyl alcohol and myristic acid. It is a colorless and odorless liquid that is a common ingredient in pharmaceutical and cosmetic preparations. [2]

Uses

Isopropyl myristate is a polar emollient and is used in cosmetic and topical pharmaceutical preparations as a penetration enhancer where skin absorption is desired. [3]

It is also used as a treatment for head lice. [4] It is also 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 is theorized to be responsible for decreasing of the pH value of formulations. [5] [6]

Adverse effects

Isopropyl myristate is frequently classified as a comedogenic compound and may worsen acne vulgaris and promote the development of open and closed comedones, especially when used in high concentrations. This effect is largely attributed to follicular hyperkeratosis, a process where the compound induces an abnormal accumulation of keratinocytes that forms a plug and causes an obstruction within a hair follicle. [3]
