Why the score varies
This ingredient is made commercially by more than one route, and ISO 16128 scores the feedstock actually used. Without a supplier certificate of origin the value cannot be claimed.
| Route | Feedstock | NOI | Share | Notes |
|---|---|---|---|---|
| fermentation-derived sphinganine + natural fatty acid | yeast/glucose fermentation plus plant fatty acid | 1.00 | ~40% | |
| total chemical synthesis | petrochemical aldehydes/alkenes | 0.00 | ~60% |
How we scored it
Where it comes from
Premium ceramides use a yeast-fermentation-derived sphinganine base acylated with a natural fatty acid. Lower-cost versions are built by total chemical synthesis from petrochemical starting materials.
In plain English
A lipid that mimics one of the fats naturally found in skin, used to condition skin and hair. It can be made from fermentation-derived building blocks or by chemical synthesis, so its origin varies by supplier.
CosIng definition: Ceramide NG, formerly known under the INCI Name Ceramide 2, is the N-acylated sphingolipid consisting of Sphinganine having the D-erythro structure linked to a normal saturated or unsaturated fatty acid. As opposed to the broader definition for Ceramide 2 which includes sphingolipids consisting of either sphingosine or dihydrosphingosine (sphinganine), Ceramide NG is limited to sphinganine-based ceramides
