How we scored it
Plant extract: all constituents derive from plant biomass (n=1); extraction solvent leaves no mass. 1.00 / 1.00 = 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
Harvested Lagenaria siceraria fruit is extracted with water, ethanol or glycerin-type solvents, then filtered. No synthetic route exists; a carrier such as propylene glycol is a separate INCI line and is not scored here.
In plain English
A skin-conditioning ingredient made by extracting the fruit of the bottle gourd (Lagenaria siceraria), a vine in the cucumber and squash family. It is a mixture of plant compounds, and its exact makeup depends on the solvent and supplier.
CosIng definition: Lagenaria Siceraria Fruit Extract is an extract of the fruit of Lagenaria siceraria, Cucurbitaceae
