CHITOSAN LAURAMIDE SUCCINAMIDE.

Valuable / EMULSION STABILISING, HAIR CONDITIONING

A sophisticated multifunctional derivative of chitosan that balances moisture retention with targeted antimicrobial support. It acts as a bio-mimetic protective shield, stabilizing formulations while providing a weightless, non-occlusive barrier for compromised skin.

Summary

Film forming Emulsion stabilizing Antimicrobial Moisture retention Skin conditioning

Science

Mechanism of Action

This ingredient utilizes its cationic (positively charged) poly-glucosamine structure to bond magnetically to the skin's naturally negative surface. It creates a breathable 'high-molecular veil' that prevents transepidermal water loss (TEWL) while the succinamide modification ensures water solubility and the lauramide chain provides essential emolliency.

Key findings

  1. 01 Demonstrated effective inhibition of P. acnes and S. aureus at a minimum concentration of 0.03%.
  2. 02 Formulations utilizing 1.0% to 2.0% significantly improved skin moisture retention by forming a durable, invisible protective film.

Because it shows biological activity against acne-causing bacteria at very low levels (0.03%), it is rarely 'dusted.' However, for moisture-retention claims, concentrations below 1.0% may not provide the full film-forming benefits.
