POTASSIUM OLIVOYL HYDROLYZED WHEAT PROTEIN.

Valuable CAS - / CLEANSING, HAIR CONDITIONING

POTASSIUM OLIVOYL HYDROLYZED WHEAT PROTEIN is a sophisticated vegetable-derived surfactant, combining the cleansing power of olive oil fatty acids with the skin-conditioning benefits of hydrolyzed wheat proteins. This unique amphiphilic structure enables effective, gentle cleansing while simultaneously supporting skin hydration and barrier function.

Summary

Emulsifying Cleansing Skin-conditioning Hair-conditioning

Science

Mechanism of Action

This ingredient functions as a gentle, amphiphilic surfactant, leveraging its olive oil-derived lipophilic (oil-attracting) and wheat protein-derived hydrophilic (water-attracting) components. This dual affinity allows it to efficiently emulsify and lift dirt and impurities from the skin's surface, facilitating removal with water. Beyond its cleansing action, it forms a protective film, imparts moisturizing properties, and helps to mitigate potential irritation from other cleansing agents, promoting balanced skin pH and moisture retention post-wash.

Stability

For optimal transparency and performance when used as a primary or co-primary surfactant at concentrations exceeding 5%, the final product pH should be precisely maintained between 5.5 and 8.0. Deviations below pH 5.5 can lead to reduced solubility and a hazy appearance. When incorporated as a secondary surfactant at concentrations below 5%, the ingredient exhibits greater pH tolerance, remaining stable down to a pH of 4.5.

Conflicts

  • Cationic surfactants (it is recommended to pre-solubilize POTASSIUM OLIVOYL HYDROLYZED WHEAT PROTEIN with amphoteric surfactants before adding cationic surfactants to avoid chemical neutralization, as this ingredient is anionic)

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Moderate

The Cosmetic Ingredient Review (CIR) Expert Panel concluded that hydrolyzed wheat protein (HWP), the foundation of this ingredient, is safe for use in cosmetics when formulated to strictly limit peptides to a weight-average molecular weight of 3500 Da or less, or to minimize peptide lengths exceeding 30 amino acids. It should not be used on damaged skin, in products that may contact mucous membranes, or in formulations with incidental inhalation risk. While dermal and ocular irritation studies indicated low irritancy and HRIPT studies found no significant sensitization, Type 1 immediate hypersensitivity reactions have been reported, particularly associated with high molecular weight (40,000-50,000 Da) forms of HWP.
