Science

Mechanism of Action

TRIMETHYLSILYL HYDROLYZED WHEAT PROTEIN PG-PROPYL METHYLSILANEDIOL CROSSPOLYMER operates through a dual-action mechanism. Its smaller molecular weight components are hypothesized to penetrate the skin and hair, delivering hydration and conditioning from within. Concurrently, its larger molecular weight fractions form a flexible, protective film on the surface, which lubricates, helps reinforce the hair cuticle, and contributes to a perceived tightening effect on the skin. Furthermore, this polymer can form siloxane cross-linked structures and potentially cross-link with hair keratin upon drying, enhancing its structural integrity and strengthening capabilities.

Conflicts

  • Avoid use on damaged skin to prevent potential adverse reactions.
  • Should not be incorporated into products that may come into contact with mucous membranes.
  • Formulations should be designed to prevent incidental inhalation.
  • Due to the hydrolyzed wheat protein component, caution is advised for individuals with known gluten allergies, as an incompatibility and potential allergic reaction exist.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Moderate

The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that Hydrolyzed Wheat Protein, a constituent of this ingredient, is safe when formulated to ensure peptide lengths do not exceed 30 amino acids (approximately 3.3 kDa). Furthermore, this ingredient is restricted from use on damaged skin, in products that may contact mucous membranes, or those where incidental inhalation is possible. There is a recognized potential for allergic reactions in individuals sensitive to gluten.
