CETYL-PG HYDROXYETHYL DECANAMIDE.

Essential CAS 143378-76-1 / SKIN CONDITIONING

A high-performance synthetic pseudo-ceramide engineered to mimic the lipid structure of the human skin barrier. It is specifically designed to restore the lamellar organization of the stratum corneum, making it a cornerstone ingredient for managing chronic dryness and barrier dysfunction.

Barrier Repair Skin Conditioning Humectant Support

Science

This lipid analog physically integrates into the intercellular lipid matrix of the skin. By replicating the architectural role of natural ceramides, it reinforces the moisture-locking lamellar bilayers, which significantly lowers transepidermal water loss (TEWL) and shields the deeper epidermal layers from external irritants.

Key findings

  1. 01 Clinical data from Kao Corporation indicates that a 3% concentration significantly elevates water-retention capacity and barrier resilience in patients with atopic dermatitis.
  2. 02 Studies on xerotic skin demonstrate that concentrations between 1.0% and 2.5% are effective for the structural restoration of lipid lamellae.

While many mass-market products claim 'ceramide support,' they often include this ingredient at sub-clinical levels (<0.5%). For therapeutic barrier repair and clinical improvement in TEWL, a minimum concentration of 1% is required.
