Is Ceramide NS natural?

Yes. Assembled from a sphingosine backbone and a fatty acid, both natural-pattern lipid building blocks, per the site's building-block rule.

How we scored it

N-acylated sphingolipid: sphingosine backbone (natural-pattern lipid) + fatty acid (oleochemical), assembled by synthesis → total/total = 1.0 (natural building blocks).
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

Manufactured by chemically joining a sphingosine backbone, made via fermentation-derived precursors, with a natural fatty acid. The assembly is synthetic but the feedstocks are natural-pattern lipids.

In plain English

A lipid that helps restore and reinforce the skin's natural moisture barrier, used in moisturisers for dry or sensitive skin. It is made by chemically joining a sphingosine backbone with a fatty acid, both natural-pattern lipid building blocks.

CosIng definition: Ceramide NS, formerly known under the INCI Name Ceramide 2, is the N-acylated sphingolipid consisting of sphingosine 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 NS is limited to sphingosine-based ceramides.
