How we scored it
Whole sphingoid-base molecule produced by yeast or plant-sugar fermentation, analogous to phytosphingosine; all 18 carbons trace to the fermentation feedstock. 301/301 = 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
Sphinganine is a sphingoid lipid naturally present in skin; the cosmetic ingredient is typically produced by fermenting yeast or plant-derived sugars rather than extracted from animal tissue. A minor chemical-synthesis route also exists.
In plain English
A lipid naturally found in skin that helps the skin barrier hold moisture. The cosmetic ingredient is typically produced by fermenting yeast or plant sugars rather than extracted from skin itself.
