SODIUM COCOYL HYDROLYZED WHEAT PROTEIN.

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

Sodium Cocoyl Hydrolyzed Wheat Protein is a versatile ingredient acting as both a gentle cleansing surfactant and an effective skin conditioning agent. It enhances skin firmness, forms a moisture-retaining film, and boosts luminosity, actively preventing dryness and diminishing the appearance of wrinkles through its key moisture-retentive amino acid, glutamic acid.

Science

Mechanism of Action

This ingredient functions primarily as a surfactant, efficiently lowering surface tension to facilitate gentle cleansing for both skin and hair. As a skin conditioning agent, it actively increases skin firmness, establishes a protective film to retain moisture, enhances skin luminosity, and aids in preventing dehydration. This comprehensive action diminishes the appearance of wrinkles and improves the skin's overall tolerance. Its notable glutamic acid content is a key factor in its effective moisture-retentive properties.

Key findings

  1. 01 Safety assessments by the Cosmetic Ingredient Review (CIR) reported Hydrolyzed Wheat Protein concentrations from 0.00002% to 1.7% in rinse-off hair products to be non-irritating to skin and eyes, and non-sensitizing in HRIPT studies.
  2. 02 The Scientific Committee on Consumer Safety (SCCS) confirmed that a 25% aqueous solution of the ingredient (with a molecular weight of 350 Da) was neither a skin nor an eye irritant in animal studies.

The CIR Expert Panel concludes safety for cosmetic use when peptide lengths are strictly controlled to a weight-average molecular weight of 3500 Da or less. Products containing this ingredient should be avoided on damaged skin or in applications with potential for mucous membrane contact or incidental inhalation, as larger peptide lengths (e.g., 40-50 kDa) have been linked to Type I hypersensitivity reactions. The FDA recognizes peptones, including hydrolyzed wheat protein, as Generally Recognized As Safe (GRAS) for direct food use.
