Ceramide

Ceramide (CAS 104404-17-3), also known as N-Acyl Sphingosine, is a sphingolipid naturally present in the skin's stratum corneum that functions as a critical structural component of the epidermal barrier.

In commercial formulations, it acts as a moisturizing and barrier-restoring agent, helping skin retain water and resist environmental stressors. It is primarily used in premium skincare formulations like moisturizers and serums.

These products replenish depleted lipid content in compromised or aging skin. In hair care, it integrates into conditioners and treatment masks to smooth the cuticle surface and reduce moisture loss along the hair shaft.

Pharmaceutical topical products targeting eczema, psoriasis, or post-procedural skin recovery incorporate this ingredient to support barrier function without active drug claims. It is a versatile component for medical skin health.

Biotechnology and life sciences researchers also use it as a reference lipid in membrane studies and liposomal delivery system development. This makes it essential for advanced laboratory applications and formulation science.

The material is supplied as a fine white to off-white powder or waxy solid, depending on the specific type and purity grade. Cosmetic-grade and pharmaceutical-grade specifications are the most commercially prevalent.

Purity levels are typically confirmed by HPLC to ensure consistency. Both synthetic and plant-derived variants are available, and buyers should confirm the source and type when evaluating their supply chain needs.

Common variations include Ceramide NP, AP, or EOP. Ensuring the correct grade and origin is vital for maintaining the efficacy and safety of the final consumer or industrial product.
