Ceramide

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

Where is Ceramide used?

• Skincare: moisturizing and barrier-restoring agent that helps skin retain water and resist environmental stressors
• Hair care: conditioners and treatment masks that smooth the cuticle surface and reduce moisture loss along the hair shaft
• Pharmaceutical topicals for eczema, psoriasis or post-procedural skin recovery support barrier function without active drug claims
• Biotechnology and life sciences: reference lipid in membrane studies and liposomal delivery system development

Good to know: Common variations include Ceramide NP, AP or EOP; buyers should confirm the source and type when evaluating supply chain needs.

Commercial specifications

• Fine white to off-white powder or waxy solid, depending on type and purity grade
• Purity levels are typically confirmed by HPLC
• Both synthetic and plant-derived variants are available
