BACILLUS/RICE BRAN EXTRACT/SODIUM GLUTAMATE/SOYBEAN SEED EXTRACT FERMENT.

Valuable / HUMECTANT

A sophisticated biotechnological complex produced through the fermentation of rice bran and soybean extracts by Bacillus subtilis. This bio-active powerhouse synthesizes high-molecular-weight polyglutamic acid to provide superior moisture retention and skin barrier fortification.

Summary

Humectant Skin Conditioning Antioxidant Barrier Repair Hyaluronidase Inhibitor

Science

Mechanism of Action

This ingredient functions through a dual-action pathway: first, it synthesizes Gamma-Polyglutamic Acid (γ-PGA), which forms a breathable film to lock in moisture while inhibiting hyaluronidase to prevent the degradation of the skin’s natural hyaluronic acid. Second, the fermentation process breaks down soy isoflavones and rice polyphenols into smaller, high-bioavailability molecules that neutralize oxidative stress and modulate inflammatory markers.

Key findings

  1. 01 Technical data indicates that at concentrations of 1-5%, the Bio-PGA produced by this complex provides moisture-retention levels that significantly outperform traditional hyaluronic acid.
  2. 02 In vitro testing showed 72.04% antioxidant activity at 100 μg/mL and significant antimicrobial effects against common skin pathogens at concentrations as low as 1.02 μg/mL.
  3. 03 Animal models studying Bacillus-fermented soybean extract demonstrated a marked reduction in atopic dermatitis-like lesions by suppressing IL-31 cytokine production and mast cell infiltration.

Because this is a complex fermented extract, many mass-market brands include it at 'label-claim' levels (below 1%) where its film-forming and hyaluronidase-inhibiting benefits are negligible.

Stability

The complex is highly stable in aqueous formulas but is heat-sensitive; it must be incorporated during the cooling phase (below 40°C) to maintain peptide integrity.
