BUTYROYL TRIHEXYL CITRATE.

Valuable CAS 82469-79-2 / PLASTICISER, SKIN CONDITIONING - EMOLLIENT

A versatile citrate ester that excels as a lightweight emollient and texture enhancer, particularly valuable in formulations requiring improved spreadability and skin conditioning. This multifunctional ingredient creates a protective barrier while preventing trans-epidermal water loss without heaviness or occlusion.

emollient plasticizer skin conditioning texture enhancer

Science

Functions as a non-polar emollient that reduces surface tension for enhanced product application while forming a lightweight, breathable film on skin that minimizes water loss. Additionally acts as a formulation stabilizer by maintaining polymer networks and preventing ingredient separation in complex formulations.
