Science
Mechanism of Action
This advanced ingredient operates as a humectant, efficiently attracting and binding water to the skin's surface to maintain optimal hydration. The inclusion of a positively charged trimonium group is engineered to enhance its adherence and bonding efficacy with both skin and hair. As a hydrolyzed collagen derivative, it provides vital amino acid precursors that are believed to stimulate fibroblasts, promoting the endogenous production of collagen, elastin, and hyaluronic acid, thereby reinforcing the skin's critical moisture barrier.

Formulation
Stability
Optimal stability is observed within a pH range of 3.68 to 5.70. This ingredient is readily soluble in cold water and does not contribute gelling properties to formulations. Studies on hydrolyzed collagen glycerosomes indicate good stability in pH and entrapment efficiency over a 12-week period at 25°C, though a slight increase in vesicle size may occur.
Safety
Safety Profile
While HYDROXYPROPYLTRIMONIUM HYDROLYZED COLLAGEN itself has not been reviewed by the Cosmetic Ingredient Review (CIR) Expert Panel, its parent compound, Hydrolyzed Collagen, was deemed safe for cosmetic applications. Major regulatory bodies including the FDA, WHO, and the European Commission generally recognize hydrolyzed collagen as safe. This specific derivative is rated 'LOW' by EWG for potential risks related to cancer, allergies & immunotoxicity, and developmental & reproductive toxicity.
