What is Stearyl Heptanoate?
Chemically, Stearyl Heptanoate is a synthetic emollient ester. A cushiony ester used in colour cosmetics and creams for a smooth payoff. Rated 4/5 for comedogenicity.
Where Stearyl Heptanoate shows up
Stearyl Heptanoate is commonly formulated into lotions, sunscreens, primers, and colour cosmetics, where it adds a smooth, non-greasy slip. Separately from clogging, its irritancy is rated 0/5 — low, so it's unlikely to sting or sensitise on its own.
Is Stearyl Heptanoate bad for acne-prone skin?
If you are acne-prone, Stearyl Heptanoate is one to watch — especially when it appears in the first few ingredients, which means it's present at higher concentration. Lower down a long ingredient list, its practical impact drops considerably.
Note for fungal-acne (malassezia) sufferers: Stearyl Heptanoate is commonly avoided in fungal-acne routines, since it falls into the fatty-acid or ester families the yeast can feed on. The evidence there is looser than for comedogenicity — see our fungal-acne checker for context.
Non-comedogenic alternatives

- Caprylic/Capric Triglyceride — rated 1/5 (Low risk).
