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 wax gourd seeds from a vegetable crop grown across Asia. No commercially significant synthetic alternative exists.
In plain English
An extract of the seeds of the wax gourd (Benincasa cerifera, also called winter melon), a vine grown as a food crop in Asia. It is listed as a skin-conditioning ingredient and is made by soaking the seeds in a solvent such as water or ethanol.
