How we scored it
Extract: all constituents are plant metabolites (n = 1); extraction solvent leaves no mass. No formula supplied. 1.0 / 1.0 = 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
Dominant route is solvent extraction (water, ethanol or glycol-water) of rapeseed (turnip rape) seeds from an oilseed crop grown widely in temperate regions. No commercially significant synthetic alternative exists.
In plain English
An extract of the seeds of rapeseed or turnip rape (Brassica campestris, now usually Brassica rapa), a crop also grown for its oil. It is listed as a skin-conditioning ingredient and is made by soaking the seeds in a solvent such as water or ethanol.
