C18-Ceramide

C18-Ceramide (CAS 2304-81-6), also known as N-stearoyl-D-erythro-sphingosine, is a naturally occurring sphingolipid that mirrors the ceramide species found in human skin.

Where is C18-Ceramide used?

• Cosmetic and pharmaceutical formulations: structural lipid and moisture-retention agent that reinforces the skin barrier
• Prestige and clinical skincare: barrier-repair creams, serums and emulsions that replenish lipids
• Restoring depleted intercellular lipids in the stratum corneum
• Topical pharmaceuticals for dry skin conditions such as eczema and psoriasis: restore lamellar lipid structure
• Liposomal and nanoparticle drug delivery: membrane-forming properties support encapsulation efficiency and controlled release
• Biotechnology and life sciences: reference lipid standard and functional component in cell membrane studies
• It reduces transepidermal water loss in clinical applications.

Commercial specifications

• Purity typically 95% to 99%+
• Packaging from small laboratory quantities to larger bulk formats
