Polyglyceryl-10 Behenate/Eicosadioate
INCI: POLYGLYCERYL-10 BEHENATE/EICOSADIOATE
A mild, plant-derived emulsifier that helps create smooth, stable creams and lotions with a silky feel.
In plain English
This ingredient is a gentle helper that allows oil and water to mix together in your skincare products, so you get a smooth, creamy texture instead of a separated mess. It's made from glycerin (a natural moisturizer) and fatty acids from plants, so it's very unlikely to irritate your skin or clog pores.

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 semi-synthetic emulsifier created by combining polyglycerin (derived from glycerin) with behenic acid (from plants like rapeseed or mustard) and eicosadioic acid (a fatty acid). It's designed to stabilize oil-and-water blends in cosmetics.
How it works
It sits at the boundary between oil and water droplets, reducing surface tension so they stay mixed. This creates a stable, uniform cream or lotion that feels smooth and spreads easily on the skin without leaving a greasy residue.
Pros
Gentle on skin
Polyglyceryl-10 Behenate/Eicosadioate has a very low irritation risk, making it suitable for sensitive skin types and daily use.
Improves product texture
It gives creams and lotions a smooth, silky feel that spreads easily without heaviness or greasiness.
Cons and cautions
Limited independent research
Most safety data comes from manufacturer studies, so long-term skin effects are not as well-documented as for some classic emulsifiers.
Not a standalone active
It's purely a formulation aid—it doesn't provide direct skin benefits like hydration or anti-aging, so it's always paired with other ingredients.
Best for
- Anyone with normal to sensitive skin looking for gentle, stable moisturizers
- People who prefer products with mild, plant-derived ingredients
Use caution if
- Those with known allergies to polyglycerin or specific fatty acids (rare)
