OLIVOYL HYDROLYZED WHEAT PROTEIN.

Valuable / CLEANSING, HAIR CONDITIONING, SKIN CONDITIONING

Olivoyl Hydrolyzed Wheat Protein is a vegetable-derived ingredient that functions as a mild surfactant, effectively cleansing the skin while simultaneously providing significant moisturizing and protective benefits. It combines the cleansing power of olive oil fatty acids with the skin-conditioning properties of wheat peptides, ensuring a gentle yet thorough purification process.

Summary

Surfactant Skin Protectant Moisturizer Conditioning Agent

Science

Mechanism of Action

This ingredient operates as a sophisticated surfactant, utilizing a unique dual molecular structure: lipophilic olive oil fatty acids bind to oils and impurities, while hydrophilic wheat peptides attract water. This allows for efficient removal of dirt without stripping the skin, leaving it feeling clean, smooth, and hydrated. Furthermore, its protein component establishes a protective barrier on the skin's surface, actively mitigating potential irritation from other cleansing agents and bolstering the skin's natural barrier function to reduce transepidermal water loss.

Stability

Demonstrates excellent stability across a broad pH spectrum, from acidic to neutral. It is particularly well-suited for formulations targeting a physiological skin pH of 5.5-6.0, which is ideal for facial and body cleansers.

Conflicts

  • In formulations containing hydrolyzed wheat protein (HWP) as a base, peptide lengths must be restricted to a weight-average molecular weight of 3500 Da (approximately 30 amino acids) or less, as per CIR guidelines.
  • Ingredients like HWP, including Olivoyl Hydrolyzed Wheat Protein, should not be applied to damaged skin or mucous membranes if peptide lengths are not adequately minimized.
  • Avoid use in products intended for incidental inhalation, such as spray formulations, in accordance with CIR recommendations for HWP.

Sensitization risk Low

The CIR Expert Panel deems the base ingredient, hydrolyzed wheat protein, safe when peptide lengths are precisely controlled to less than 3500 Da. For Olivoyl Hydrolyzed Wheat Protein specifically, irritation tests on human volunteers have confirmed its non-irritating nature, and it is considered non-comedogenic. The SCCS also concurs that hydrolyzed wheat protein does not irritate the skin. The FDA classifies peptones, which include hydrolyzed proteins, as Generally Recognized As Safe (GRAS) for direct food use.
