What it is
This ingredient is a polyol ester made by reacting pentaerythritol with a blend of adipic, capric, caprylic, and heptanoic acids. The result is a stable, spreadable oil-phase material that conditions skin and improves the feel and structure of a formula. It is commonly used in color cosmetics and sun-care products to bind pigments, carry filters, and impart a smooth, cushioned skin feel.
Safety & warnings
Pentaerythrityl esters of this type are generally well tolerated and are not recognized fragrance allergens. As a fatty ester it contributes to the oil phase and could feel heavy in very high amounts, but it is widely used without notable sensitization concerns.
Origin & sourcing
Synthetic. It is manufactured by esterifying pentaerythritol with a defined mixture of fatty and dicarboxylic acids; the acid feedstocks may be derived from plant or petrochemical sources.
