BUTYL ETHYLPROPANEDIYL ETHYLHEXANOATE.

Valuable / SOLVENT

A specialized synthetic ester that serves as a high-performance solvent and lightweight emollient in cosmetic formulations. This ingredient excels at dissolving challenging actives like UV filters while providing smooth, non-greasy skin conditioning that works across all skin types.

solvent emollient

Science

Acts as a dual-function ingredient by solubilizing poorly water-soluble compounds through its high-polarity solvent properties, while simultaneously functioning as an emollient that fills intercellular gaps to smooth skin texture without residual greasiness.
