How we scored it
C16H24O3 (264.4 Da): natural octanoyl C8H15O 127.2 Da; petrochemical phenoxyethyl-O C8H9O2 137.2 Da (phenol + ethylene oxide); 127.2 / 264.4 = 0.48.
What counts. ISO 16128-2 scores the atoms that remain in the final ingredient. Reagents, solvents, catalysts and protecting groups used during manufacture leave no mass behind and are not counted.
Where it comes from
Oleochemical caprylic acid is esterified with petrochemical phenoxyethanol. No natural-origin route for the phenoxyethanol part is commercial.
In plain English
An ester of caprylic acid and phenoxyethanol used as a low-viscosity emollient and solvent in skin-care and make-up products. It helps dissolve other ingredients and gives a smooth feel. The fatty acid part comes from coconut or palm kernel oil; the alcohol part is synthetic.
CosIng definition: Phenoxyethyl Caprylate is the organic compound.
Structure
2-phenoxyethyl octanoate
