What is Glyceryl Stearate SE?
Glyceryl Stearate SE falls into the emulsifier category — an emulsifier that helps oil and water mix. The self-emulsifying (SE) grade of glyceryl stearate carries added soap and rates higher than the plain form, at 3/5. The non-SE grade is far milder.
You may see it on labels as Glyceryl Stearate Se, Glyceryl Stearate (Se), Glyceryl-3 Diisostearate, Glyceryl 3-Diisostearate, so it can hide under more than one name in an ingredient list.
Where Glyceryl Stearate SE shows up
As an emulsifier that helps oil and water mix, Glyceryl Stearate SE typically appears in almost any lotion or cream, where it keeps the oil and water phases blended. Separately from clogging, its irritancy is rated 2/5 — low, so it's unlikely to sting or sensitise on its own.
Is Glyceryl Stearate SE bad for acne-prone skin?
A moderate rating means Glyceryl Stearate SE clogs some people and not others. If you're prone to congestion, patch-test a product that features it prominently before committing.
Note for fungal-acne (malassezia) sufferers: Glyceryl Stearate SE 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
If you're avoiding Glyceryl Stearate SE, these lower-risk ingredients serve a similar role and are gentler on pore-prone skin:
- Glyceryl Stearate — rated 1/5 (Low risk).
- Cetearyl Alcohol — rated 2/5 (Low risk).
