How we scored it
Glucose 162.1 Da + ceramide NP (stearic acid + phytosphingosine), all natural; protecting groups leave no mass, so 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 route glycosylates fermentation-derived ceramide NP (yeast phytosphingosine acylated with vegetable stearic acid) with glucose. Fully synthetic ceramide exists but is not the main supply.
In plain English
A skin-identical lipid made by attaching glucose to ceramide NP, used to hold moisture and condition hair. The glucose comes from starch and the ceramide from yeast-fermented phytosphingosine and vegetable stearic acid.
CosIng definition: Glucosyl Ceramide NP is the product obtained by the reaction of Glucose and Ceramide NP.
