Isopropyl Myristate

Isopropyl Myristate is an ester of isopropyl alcohol and myristic acid, commonly used as an emollient and thickening agent. It helps to reduce the greasy feel of heavy oils and improves the spreadability of cosmetic products. It can also enhance the penetration of other ingredients into the skin.

Isopropyl Myristate is known to be highly comedogenic, meaning it can clog pores and is generally not recommended for individuals with acne-prone or oily skin types.
