How we scored it
Mesua ferrea seed extract: every constituent is plant-derived (n=1); extraction solvent leaves no mass in the substance. 1.0 x 100% = 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
Dominant feedstock is the seed of Mesua ferrea (ironwood, nagkesar) extracted with a solvent. No alternative route exists; any carrier solvent is declared as its own ingredient.
In plain English
An extract of the seeds of Mesua ferrea, a tropical tree known as ironwood or nagkesar, made by soaking them in a solvent. It is listed as a skin-conditioning ingredient. It comes entirely from the seed.
