What is Isopropyl Myristate?
Isopropyl myristate is a synthetic ester of isopropyl alcohol and myristic acid (from nutmeg or palm kernel oil). It is a dry, silky-feeling emollient that also acts as a penetration enhancer.
Why is Isopropyl Myristate used in personal-care products?
Used to reduce the greasy feel of oils in cosmetics, improve spreadability, and enhance the skin penetration of active ingredients. Common in sunscreens, hair serums, and body lotions.
What regulators have flagged about Isopropyl Myristate
Isopropyl myristate is CIR-safe at cosmetic use concentrations. Like IPP, it has a notable comedogenicity rating (3–4/5) and may contribute to clogged pores in acne-prone users. Its penetration-enhancing properties mean that whatever active ingredients it accompanies are delivered more deeply into the skin — this is generally desirable but should be noted. No carcinogenic or endocrine-disrupting effects are documented.
