Science
Mechanism of Action
This ingredient operates as a dual-action conditioning agent. On the skin, it actively works to maintain optimal health by delivering essential nutrients, fostering a softer, smoother, and more hydrated epidermal layer. It can also contribute emollient properties. In hair applications, its unique mechanism involves plasticizing the hair by moisturizing from within while simultaneously lubricating the outer hair surface to protect the cuticle. This dual approach significantly strengthens hair and enhances its resistance to damage. Overall, it is designed to penetrate and condition both hair and skin effectively.

Key findings
- 01 In hair applications, a conditioner formulated with 1% Hydrolyzed Vegetable Protein PG-Propyl Silanetriol delivered a threefold increase in strengthening performance compared to the conditioner alone. This improvement was observed through enhanced hair strength and increased resistance to breakage in flexabrasion studies.

Stability
Exhibits stability under normal storage conditions but requires protection from extreme temperatures and direct sunlight. It generally performs well across a neutral to slightly acidic pH range.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that Hydrolyzed Pea Protein, the foundational ingredient, is safe for use in cosmetic formulations. While a specific CIR assessment for the PG-Propyl Silanetriol derivative is not explicitly available, INCI Beauty reports 'No penalty' across all categories for this ingredient, and SkinSAFE identifies it as 'Irritant Free'. However, some sources indicate limited comprehensive safety data for the derivative. The maximum concentration of 1% is based on recommended use levels in hair care applications. Plant protein products are also approved food additives by the FDA and generally recognized as safe (GRAS) for food use.
