Ceramide NP

Ceramide NP (CAS 178436-06-1), also known as N-Oleoylphytosphingosine, Ceramide 3B, Ceramide IIIB, and traded under names such as DS-Y 30, is a naturally occurring sphingolipid belonging to the ceramide family. It carries no assigned E-code and is classified under Oils, Fats and Waxes with the molecular formula C36H71NO4.

In personal care formulations, Ceramide NP restores and reinforces the skin's lipid barrier by integrating into the intercellular lamellar structure of the stratum corneum, reducing transepidermal water loss. In pharmaceutical topical preparations, it supports membrane integrity and aids active delivery by modifying surface wetting behaviour at the skin interface.

Ceramide NP is supplied as a solid and is available for cosmetic and pharmaceutical-grade applications in compliance with REACH regulations. Procurement teams should confirm grade specification, batch documentation, and packaging format directly with the supplier to meet formulation and regulatory requirements.
