How we scored it
Isosorbide C6H10O4 146.1 (from sorbitol) + 2 octanoic acids 288.4 - 2 water 36.0 = 398.5; every fragment natural: 398.5/398.5 = 1.00.
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
Corn or wheat starch is hydrolysed to glucose, hydrogenated to sorbitol and dehydrated to isosorbide, then esterified with oleochemical caprylic acid. No commercially significant petrochemical route is known.
In plain English
A light, non-greasy emollient oil that softens skin and helps spread other ingredients. It is made by joining isosorbide, a sugar-alcohol derivative from starch, with caprylic acid from coconut or palm kernel oil.
CosIng definition: Isosorbide Dicaprylate is the diester of isosorbide and caprylic acid
Structure
[(3S,3aR,6R,6aR)-6-octanoyloxy-2,3,3a,5,6,6a-hexahydrofuro[3,2-b]furan-3-yl] octanoate
