BUTTER DECYL ESTERS.

Valuable / EMULSION STABILISING, HAIR CONDITIONING, SKIN CONDITIONING

A refined emollient derived from butter fatty acids through transesterification with decyl alcohol, creating a lightweight alternative to traditional heavy fats. This advanced ester delivers superior skin conditioning properties with a distinctive dry-oil finish that eliminates the greasy residue typically associated with butter-based ingredients.

Science

Functions by integrating into the intercellular spaces between desquamating corneocytes, establishing a protective lipid layer that reinforces barrier integrity and prevents moisture loss. The lower molecular weight structure and reduced melting point compared to parent butter compounds enables enhanced spreadability and absorption while maintaining emollient efficacy.
