Science

Mechanism of Action

COCODIMONIUM HYDROXYPROPYL HYDROLYZED OAT/RICE/SOY PROTEIN delivers a complex of hydrolyzed botanical proteins alongside a cocodimonium hydroxypropyl quaternary ammonium compound. On the skin, it forms a protective, breathable film that reinforces the natural barrier and significantly reduces transepidermal water loss. The hydrolyzed soy protein component, rich in isoflavones, exhibits antioxidant properties to combat photoaging, encourages cellular renewal, and stimulates the synthesis of hyaluronic acid and collagen, which collectively improve skin elasticity and diminish wrinkle appearance. Hydrolyzed oat protein contributes a soothing, flexible layer that protects and nourishes while retaining natural moisture. Hydrolyzed rice protein enhances hydration by increasing the skin's moisture-binding capacity and acts as an anti-irritant. The cationic cocodimonium hydroxypropyl group further contributes to the overall conditioning effect, leaving skin soft and smooth.

Stability

This ingredient is optimally stable within a pH range of 4.0 to 5.0, ensuring the integrity of all protein components. While the hydrolyzed oat protein component can tolerate up to pH 7.0, a narrower range is preferred for the combined ingredient. To preserve its efficacy, avoid exposing the ingredient to temperatures exceeding 40°C (104°F) during formulation.

Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that its constituent hydrolyzed soy and rice proteins are safe for cosmetic use. The highest reported maximum concentration for a component, hydrolyzed soy protein, is 3.5% in mascara. While INCIDecoder lists irritancy and comedogenicity as 'unknown' for similar ingredients, SkinSAFE identifies related Cocodimonium Hydroxypropyl Hydrolyzed Rice Protein and Soy Protein as 'Irritant Free' and 'Baby SAFE', suggesting a low potential for irritation. It is noted that for Cocodimonium Hydroxypropyl Hydrolyzed Rice Protein, EWG points to potential contamination concerns from toxic impurities, which could elevate its hazard score, as it is a quaternary ammonium chloride. Cosmetics ingredients in the US do not require FDA pre-market approval but must be safe for their intended use.
