Ceramide 3

Ceramide 3 (CAS 34354-88-6), also marketed under the trade name Cellapy A Repair, is a synthetic sphingolipid that mirrors the ceramides naturally present in the skin's stratum corneum. It functions as a barrier-reinforcing and moisture-retention agent in topical formulations, helping to restore lipid structure in compromised or aging skin. In premium skincare, it is incorporated into moisturizers and serums.

These products replenish depleted intercellular lipids and reduce transepidermal water loss. It is used in dermocosmetic formulations targeting eczema-prone, sensitive, or post-procedure skin for optimal recovery. Formulators often combine it with cholesterol and fatty acids to replicate the natural lamellar bilayer. Hair care formulators use it in conditioning treatments and leave-on products to smooth the cuticle.

This ingredient improves fiber integrity and overall hair health. Pharmaceutical topical preparations also incorporate it where skin barrier restoration is a documented clinical endpoint for patient care. The material 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 for use.

Quality is maintained according to strict industry standards for safety and efficacy. Packaging ranges from small quantities for R&D sampling to kilogram-scale lots for commercial formulation needs.
