How we scored it
Sophorolipids: sophorose (two glucose units) plus hydroxy fatty acid from rapeseed oil, both n=1; acetyl groups come from yeast metabolism; methanol of the ester is lost. All mass n=1, so 1 / 1 = 1.0.
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
Glucose and rapeseed methyl ester are fed to the yeast Candida (Starmerella) bombicola, which secretes sophorolipid biosurfactants that are then separated. No alternative route is in commercial use for this INCI.
In plain English
A cleansing, deodorising and antimicrobial ingredient made of sophorolipids, sugar-based surfactants produced by yeast. The yeast is fed glucose and rapeseed oil derivatives, and the product is purified from the fermentation broth.
CosIng definition: Product obtained by the fermentation of glucose and methyl rapeseedate by the microorganism Candida bombicola
