PG-HYDROLYZED RICE PROTEIN.

Valuable / HAIR CONDITIONING, SKIN CONDITIONING

PG-Hydrolyzed Rice Protein is a low molecular weight protein derivative, rich in beneficial peptides and amino acids, engineered to deeply hydrate and protect the skin. It forms a non-tacky, moisture-retentive film while delivering essential nutrients to support skin health and resilience.

Summary

Hydrating Protective Anti-aging Antioxidant Anti-inflammatory Sebum-regulating Skin-repairing Barrier-supporting

Science

Mechanism of Action

This ingredient operates by forming a breathable, protective film on the skin's surface, effectively minimizing transepidermal water loss and enhancing resistance to environmental aggressors. Its small molecular size facilitates deeper penetration, delivering crucial amino acids that are vital for stimulating collagen and elastin synthesis. This action strengthens the skin's natural barrier, promotes repair processes, and significantly increases cellular water content, leading to a hydrated and supple complexion. Furthermore, it provides antioxidant defense against free radicals, reduces inflammation, and assists in balancing sebum production, ultimately improving skin texture and elasticity.

Stability

For optimal stability in cosmetic formulations, PG-Hydrolyzed Rice Protein should be incorporated into the water phase. It is best added during the cool-down phase or during cold-processing, ensuring temperatures remain below 40°C (104°F). Optimal storage for maximum shelf life is between 23-25°C, with a permissible range of 16-32°C. Freezing should be avoided.

Conflicts

  • strong oxidizers
  • other protein treatments (risk of over-proteinization)

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has affirmed that Hydrolyzed Rice Protein is safe for cosmetic applications. It is generally well-tolerated across most skin types, with no significant adverse effects reported, although initial patch testing is a prudent measure. Rice is widely regarded as non-allergenic, and the FDA recognizes plant protein products as approved food additives.
