BUTYLOCTYL BENZOATE.

Valuable CAS 188038-97-3 / PLASTICISER, SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT, SOLVENT

A specialized emollient and solvent engineered to enhance sunscreen performance by photostabilizing UV filters, particularly avobenzone. This high-polarity compound creates a uniform protective film while delivering superior solvency properties that significantly boost SPF values and extend UV-A protection duration.

emollient solvent UV filter enhancer

Science

Acts as a high-polarity solvent that dissolves crystalline UV filters and pigments, enabling uniform distribution across skin while preventing photodegradation of chemical sunscreen actives through enhanced molecular stability
