Hydrolyzed Vegetable Protein PG-Propyl Silanetriol is a copolymer of vegetable protein and silicone. It is a powerful hair-strengthening ingredient that dramatically improves the strength of damaged hair. It contains low molecular weight components that penetrate the cortex and moisturize from within, and high molecular weight components that form a film on the hair shaft and lubricate and reinforce the cuticle.
It is a silanol-terminated peptide with a reactive silane. When applied to the hair, the silanol groups can cross-link with one another to form a siloxane cross-linked copolymerupon drying. Moreover, silane groups can cross-link to the hair keratin.
Due to its dual action, Hydrolyzed Vegetable Protein PG-Propyl Silanetriol plasticizes the hair by moisturizing from within and lubricates the outer hair surface to protect the cuticle. Together, these properties help strengthen the hair and reduce damage from chemical treatments or styling practices.
Flexabrasion studies show a conditioner with 1% Hydrolyzed Vegetable Protein PG-Propyl Silanetriol provides three times the strengthening performance of the conditioner alone. Its ability to strengthen hair has been demonstrated using flexabrasion. This technique allows for the evaluation of the entire aspect of hair strength: fiber extension, fiber flexure, and cuticle abrasion.In flexabrasion studies, treatment with Hydrolyzed Vegetable Protein PG-Propyl Silanetriol increased hair strength, as hair fibers treated with this ingredient exhibited a higher fatigue lifetime, indicating greater resistance to breakage. This translates into increased hair strength. According to the manufacturer, it is a safe ingredient for hair care applications derived from an upcycled vegetable source. It is readily biodegradable, and the recommended use level is 0.25 - 1%.
