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.
Is Isopropyl Myristate dangerous? Documented risks
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.

How to avoid Isopropyl Myristate: safer alternatives
Squalane, jojoba oil, or caprylic/capric triglyceride for a non-comedogenic alternative with a similarly lightweight skin feel.
Frequently asked questions about Isopropyl Myristate
Does isopropyl myristate cause acne?
It is moderately to highly comedogenic and may trigger breakouts. Acne-prone individuals should look for it in product ingredient lists and consider avoiding it in leave-on face products.
Is IPM a penetration enhancer?
Yes. Isopropyl myristate disrupts the lipid packing in the stratum corneum temporarily, allowing co-formulated actives to penetrate more deeply. This is intentionally exploited in therapeutic topical formulations.
