Hair conditioning Skin conditioning Surfactant Antistatic Emollient Film-forming Humectant Reduces harshness of other surfactants

Science

Mechanism of Action

This ingredient functions by improving skin's texture and moisture retention, effectively reducing flaking and restoring suppleness through its skin-conditioning properties. As a humectant, its water-binding capabilities contribute to a soft, smooth, and hydrated feel. Additionally, it serves as a mild surfactant, aiding in the gentle removal of oil and dirt from the skin and hair. Its hydrolyzed collagen fragments are thought to mimic natural collagen peptides, potentially supporting the skin’s own repair mechanisms and contributing to a more elastic complexion, minimizing the appearance of fine lines and wrinkles.

The CIR Expert Panel has repeatedly affirmed its safety for cosmetic use, including reaffirmatons in 2002 and 2025. Concentrations up to 20% have been found non-irritating in human patch tests. A human repeated-insult patch test (HRIPT) at 10% aqueous concentration on 168 subjects showed minimal reactions (2 allergic sensitizations, 2 cumulative irritations, 1 mild non-specific irritation), indicating a generally low sensitization risk.
