Propylene Glycol Myristyl Ether Acetate
INCI: PROPYLENE GLYCOL MYRISTYL ETHER ACETATE
A gentle synthetic emollient that helps products glide on smoothly without heavy greasiness.
In plain English
This is a lab-made ingredient that helps lotions and creams feel silky and spread easily on your skin. It works by forming a thin, non-greasy film that softens the skin's surface and reduces water loss, but it doesn't clog pores or cause irritation for most people.

Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Propylene Glycol Myristyl Ether Acetate.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A synthetic ester derived from propylene glycol, myristyl alcohol, and acetic acid. It is a clear, oily liquid used in cosmetics to improve texture and skin feel.
How it works
It sits on the skin's surface as an emollient, filling in gaps between skin cells to smooth roughness and temporarily soften the skin. It also helps other ingredients spread evenly and can enhance the absorption of active ingredients.
Pros
Lightweight feel
Leaves skin soft without a heavy or sticky residue, making it ideal for daytime use and oily skin types.
Low irritation potential
Clinical data and safety reviews indicate it rarely causes allergic reactions or stinging, even on sensitive skin.
Cons and cautions
Synthetic origin
Derived from petrochemicals, which may be a concern for consumers seeking natural or sustainable ingredients.
Limited independent research
Most safety data comes from manufacturer studies; long-term skin health effects are not extensively studied in peer-reviewed literature.
Best for
- People with normal to oily skin who want lightweight moisture
- Anyone looking for a non-greasy emollient in lotions or makeup
Use caution if
- Those strictly avoiding all synthetic ingredients
- Individuals with known sensitivity to propylene glycol derivatives (rare)
Usage tips
Safety summary
Considered safe for use in cosmetics at typical concentrations. The Cosmetic Ingredient Review (CIR) panel has evaluated similar ether acetates and found them safe when formulated properly. Rare reports of mild irritation exist, but overall risk is low.
Research notes
Safety assessments rely on analog studies and manufacturer data. No large-scale human trials are available, but decades of use without major safety signals support its safety profile.
Common label clues
