ASPERGILLUS/DEFATTED SOYBEAN SEED FERMENT EXTRACT.

Valuable / ANTIMICROBIAL, BUFFERING, HUMECTANT, PRESERVATIVE

A precision-engineered bioactive ferment produced by the enzymatic action of Aspergillus on soybean proteins to release specialized Koji Polysaccharides. This extract serves as a sophisticated barrier-repair agent that targets the biological pathways of skin irritation and microbiome imbalance.

Skin-conditioning Humectant Anti-inflammatory Barrier-repair Microbiome-support Anti-microbial

Science

This extract modulates the skin's inflammatory response by suppressing Th2 cytokines, such as IL-4, and inhibiting Nerve Growth Factor (NGF)-induced dendritic cell extension to effectively reduce pruritus (itching). Its high concentration of Koji Polysaccharides (IBF) accelerates structural barrier recovery and balances the skin microbiome, while simultaneous tyrosinase inhibition provides a secondary benefit of tone evening.

Key findings

  1. 01 Clinical application of a 0.2% Koji Polysaccharide fraction resulted in significant objective and subjective improvement in atopic dermatitis symptoms and inflammatory markers over a 30-day period.
  2. 02 In vitro testing demonstrated a measurable inhibition of adipocyte differentiation and lipid accumulation, suggesting potential applications in lipid regulation and body contouring.

With clinical efficacy established at a low threshold of 0.2%, this ingredient is frequently included at 'label-only' concentrations (below 0.1%) in mass-market formulations to claim fermented-soy benefits without delivering the therapeutic anti-atopic response.

Stability

Highly heat-sensitive; bioactive polysaccharides degrade if exposed to temperatures above 40°C during manufacture. Must be incorporated during the cool-down phase.
