Ethylhexyl Stearoyl Polyhydroxystearate
INCI: Ethylhexyl Stearoyl Polyhydroxystearate
A gentle synthetic ester that helps blend pigments and oils, giving products a smooth, non-greasy feel with low irritation risk.
In plain English
This ingredient is a type of synthetic oil that helps mix other ingredients together, especially pigments in makeup or sunscreen. It spreads easily on skin and leaves a silky, non-greasy finish. Because it's made to be very mild, it rarely causes breakouts or irritation, making it a common choice for sensitive skin formulas.

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.

What it is
A synthetic ester derived from stearic acid and polyhydroxystearic acid, designed to improve the texture and stability of cosmetic products.
How it works
It acts as a dispersant, keeping solid particles like pigments or sunscreen minerals evenly suspended in the formula. It also functions as an emollient, softening the skin and reducing the greasy feel of heavier oils.
Pros
Gentle on skin
Rated low for both irritation and comedogenicity, so it's unlikely to cause breakouts or redness, even for sensitive skin types.
Improves makeup performance
Helps pigments and sunscreen minerals spread evenly, reducing patchiness and improving the overall look of foundation or tinted SPF.
Cons and cautions
Synthetic ingredient
Not derived from natural sources, which may be a drawback for those who prefer plant-based or organic formulations.
Limited independent research
Most safety data comes from manufacturer studies; long-term skin effects are not extensively studied in independent research.
Best for
- People with sensitive or acne-prone skin
- Anyone using tinted sunscreens or foundations
Use caution if
