COCODIMONIUM HYDROXYPROPYL HYDROLYZED SOY PROTEIN.

Valuable / ANTISTATIC, HAIR CONDITIONING, SKIN CONDITIONING, SURFACTANT - CLEANSING

This ingredient is a water-soluble skin and hair conditioning agent, derived from hydrolyzed soy protein. It enhances skin hydration, texture, and firmness while offering antioxidant protection against environmental stressors. Its hydrolyzed nature allows for optimized skin penetration, delivering its beneficial peptides more effectively.

Science

Mechanism of Action

COCODIMONIUM HYDROXYPROPYL HYDROLYZED SOY PROTEIN functions primarily as a skin conditioning agent, actively supporting skin health and appearance. The hydrolysis process breaks down soy protein into smaller peptides, which are believed to facilitate deeper penetration into the epidermal layers. This deeper action contributes to improvements in skin firmness, texture, elasticity, and hydration, while also imparting antioxidant benefits. Additionally, it acts as an antistatic agent, reducing static build-up, and as a surfactant, aiding in the even dispersion of cosmetic formulations.

Stability

Hydrolyzed soy protein ingredients generally exhibit water solubility. The solubility of soy protein isolate is pH-dependent, showing a U-shaped curve with minimal solubility near its isoelectric point (approximately pH 4.6), and increased solubility under both acidic (e.g., pH 2.0) and alkaline conditions (e.g., pH 9.0-11). Typical processing for hydrolyzed soy protein involves pH adjustment to 7.0 for enzyme deactivation, and extraction from soy flour often utilizes pH 8.0-9.0. Specific optimal pH stability for COCODIMONIUM HYDROXYPROPYL HYDROLYZED SOY PROTEIN is not specified. Certain salts, such as gypsum powder, may decrease its solubility.

Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has deemed soy proteins and peptides, including Hydrolyzed Soy Protein, safe for cosmetic use within current practices and concentrations. Studies indicate Hydrolyzed Soy Protein was not a dermal irritant in human or animal tests at concentrations up to 25%. Similarly, it did not act as a dermal sensitizer in human and non-human studies at up to 25%. In vitro ocular assays predicted it to be non-irritating to slightly irritating at concentrations up to 35%. The highest reported cosmetic use concentration for Hydrolyzed Soy Protein was 3.5% in mascara. The FDA recognizes soy proteins as Generally Recognized As Safe (GRAS) for food consumption. A single case study noted rosacea aggravation in a patient using soy-containing facial products, but this is an isolated incident.
