What it is
This ingredient is produced by esterifying decaglycerin (polyglyceryl-10) with two units of stearic acid, giving a mild nonionic emulsifier with a more solid, waxy character than its oleate counterpart. It helps stabilize emulsions and can support thicker, creamier textures in sunscreens and moisturizers. It also contributes a smooth, conditioned skin feel.
Safety & warnings
Polyglyceryl-10 esters are nonionic and generally regarded as mild and well tolerated, with low irritation and sensitization potential and no fragrance-allergen concern.
Origin & sourcing
Synthetic; made by combining plant-derived glycerin (as polyglycerin-10) with stearic acid, which is commonly of vegetable origin.
Questions everyone asks
How does it differ from polyglyceryl-10 dioleate?
It is esterified with stearic acid rather than oleic acid, giving it a more solid, waxy character suited to richer textures.
Is it suitable for sensitive skin?
As a mild nonionic emulsifier, it is generally well tolerated and commonly used in gentle formulations.
