Ceramides

Ceramides (CAS 100403-19-8), commercially known as Ceramide NP, Ceramide IIIB, and CER NP, are sphingolipid-based actives that restore and reinforce the skin's natural lipid barrier.

They are a primary ingredient class in premium skincare and pharmaceutical topical formulations where barrier repair and moisture retention are the core performance targets for the end user.

In moisturizers, serums, and barrier creams, Ceramide NP replenishes depleted intercellular lipids in the stratum corneum, directly addressing dry, compromised, or aging skin conditions effectively.

Dermatological formulations for eczema and atopic dermatitis rely on ceramide-based systems to restore the lipid matrix disrupted by these conditions and improve overall patient outcomes.

In prestige and clinical skincare lines, Ceramide NP is frequently combined with cholesterol and fatty acids in a defined molar ratio to replicate the natural lamellar structure of skin lipids.

Hair care products, particularly conditioning treatments and bond-repair systems, use ceramides to smooth the cuticle layer and reduce moisture loss along the hair shaft for better texture.

Ceramide NP is supplied as a white to off-white powder or waxy solid. It is available in cosmetic-grade and pharmaceutical-grade specifications, with purity levels typically at 95% or higher.

Synthetic and plant-derived variants are both commercially available, and grade selection is a key sourcing decision for formulators targeting clean-label or vegan positioning in the market.
