Science
Mechanism of Action
This ingredient operates by deeply penetrating the skin's surface, delivering beneficial peptides and amino acids due to its small molecular weight. It significantly boosts skin hydration by increasing endogenous water content, thereby improving skin elasticity and tensile strength for a more supple complexion. Concurrently, it stimulates collagen synthesis, which aids in smoothing the appearance of fine lines and wrinkles. The ingredient also exhibits antioxidant capabilities, actively combating free radicals and mitigating oxidative stress. Furthermore, it possesses soothing properties, calming irritated skin and reducing inflammation, while forming a protective film to lock in moisture and defend against environmental aggressors.

Stability
This hydrolyzed rice protein derivative demonstrates improved water solubility, particularly stable and effective within a broad pH range of 4 to 10. Maximum solubility is observed at higher alkaline pH levels, specifically between 10-12, which contrasts with native rice protein's poor solubility in the pH 2–10 range, showing a minimum at pH 5.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed 'Hydrolyzed Rice Protein' safe for cosmetic applications, noting it is non-acutely toxic, non-irritating to skin or eyes in animal studies, and non-sensitizing in both animal and human clinical tests. While 'Potassium Capryloyl Hydrolyzed Rice Protein' has not been individually assessed by CIR or SCCS, its classification as a hydrolyzed protein derivative suggests a generally favorable safety profile. It is typically considered non-irritating, though caution is advised when combined with other potentially problematic ingredients.
