What it is
This ingredient is a highly branched ester formed by reacting dipentaerythritol with a mixture of C5-9 fatty acids. Its dense, branched structure gives a rich yet non-greasy slip and makes it effective at wetting and dispersing pigments, which is useful in tinted and tone-up sunscreens. It also helps adjust viscosity and improve the cushiony texture of creams and sticks.
Safety & warnings
Polyol esters of this kind are generally well tolerated and considered low in irritation and sensitization potential at cosmetic levels.
Origin & sourcing
Synthetic ester made by esterifying dipentaerythritol with short- to medium-chain fatty acids.
