Science

Mechanism of Action

POTASSIUM ISODECYL/ISOSTEAROYL HYDROLYZED RICE PROTEIN operates by delivering readily absorbed peptides and amino acids due to its optimized molecular size. It actively supports the skin's natural collagen and elastin production, contributing to enhanced barrier function and aiding in epidermal repair. Functioning as a potent humectant, it attracts and retains moisture, fostering a hydrated and supple skin surface. The isodecyl/isostearoyl modification significantly boosts its emollient capabilities, promoting a smooth skin feel and improving its integration within oil-based formulations. Furthermore, it forms a protective film to reduce moisture loss and shield against environmental stressors, while also contributing anti-irritant, anti-inflammatory, antioxidant, and sebum-regulating properties.

Key findings

  1. 01 General Hydrolyzed Rice Protein demonstrated a significant increase in total hair volume (up to 32-44%) after 5 treatments in leave-on hair products, at concentrations of 1-10%.
  2. 02 Rice Protein Hydrolysates (RPHs) inhibited hyaluronidase (an enzyme that degrades hyaluronic acid) in a dose-dependent manner with an IC50 of 8.91 mg/mL, suggesting anti-aging potential.
  3. 03 Rice Protein Hydrolysates (RPHs) inhibited tyrosinase (an enzyme involved in melanin synthesis) in a dose-dependent manner with an IC50 of 107.6 mg/mL, indicating potential for skin brightening.
