Science
Mechanism of Action
As a sophisticated skin conditioning agent, STEARDIMONIUM HYDROXYPROPYL HYDROLYZED VEGETABLE PROTEIN utilizes its small-peptide structure, derived from hydrolyzed vegetable sources, to effectively penetrate the skin's surface. Its amino acid composition contributes to the formation of a protective film, which bolsters the skin's barrier function, significantly enhances moisture retention, and supports improved elasticity. This multifaceted action culminates in a refined skin texture and a perceptibly firmer appearance.

Stability
For optimal stability, formulations incorporating Hydrolyzed Vegetable Protein components should be maintained within a pH range of 4.0 to 7.0. Solubility is particularly enhanced in acidic conditions, specifically between pH 4 and 5.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed 'Hydrolyzed Vegetable Protein' safe for use in cosmetic products. While it is generally considered to have low irritancy (a similar ingredient, Steardimonium Hydroxypropyl Hydrolyzed Wheat Protein, is 'Irritant Free' according to SkinSAFE, and a 50% concentration was not sensitizing in a Buehler Test), individuals with known allergies to specific source proteins (e.g., tree nut, seed, avocado) may experience Type I immediate hypersensitivity reactions. The broader 'PROTEIN, VEGETABLE, HYDROLYZED' is listed as GRAS by the FDA for food use.
