DESCRIPTION
What It Does: Provides emollient skin conditioning with specific spreading value determined by the acid-alcohol ester molecular architecture.
Why It's Used: Borago officinalis ethyl ester is selected for its ester molecular architecture โ the specific acid and alcohol fragments of borago officinalis ethyl ester determine the logp, spreading coefficient, and skin adhesion profile unavailable from any other functional ingredient class.
How It Works: Ester polarity (logp) controls spreading: branched short-chain fast dry; medium moderate spreading; long chain occlusive. ester c=o provides polar adhesion to skin.
