CETEARAMIDOETHYLDIETHONIUM SUCCINOYL HYDROLYZED SOY PROTEIN.

Valuable / HAIR CONDITIONING

A sophisticated biomimetic lipid-protein complex designed to restore the skin's protective F-layer. By mimicking the natural 18-MEA structure found in healthy tissue, it provides targeted repair to compromised barrier sites.

Barrier Repair Skin Conditioning Humectant Protection Anti-static

Science

This cationic ingredient utilizes selective adsorption to identify and bind to negatively charged, damaged areas of the skin. It acts as a 'pseudo-18MEA' agent, depositing a breathable, hydrophobic film that reinforces the stratum corneum and prevents transepidermal water loss.

Key findings

  1. 01 Concentrations as low as 1.0% significantly reduce TEWL and restore the hydrophobic barrier on damaged surfaces.
  2. 02 At 3.0%, fluorescence microscopy confirms immediate recovery of barrier architecture and measurable improvements in skin texture.
