BACILLUS/HOUTTUYNIA CORDATA LEAF/SOYBEAN FERMENT FILTRATE.

Valuable CAS - / BLEACHING, HAIR CONDITIONING, SKIN PROTECTING

A high-performance bio-fermented complex that merges the soothing properties of Houttuynia cordata (Heartleaf) with the nutrient-dense profile of Soybean. Through Bacillus-mediated fermentation, the raw plant materials are enzymatically converted into smaller, more bioavailable molecules for superior dermal penetration and antioxidant defense.

skin conditioning antioxidant soothing brightening anti-elastase

Science

The fermentation process utilizes Bacillus species to biotransform soybean isoflavone glycosides into bioactive aglycones like genistein and daidzein, while simultaneously breaking down Heartleaf proteins into low-molecular-weight peptides. This molecular refinement enhances the concentration of flavonoids, which actively inhibit elastase to protect collagen structures and suppress pro-inflammatory cytokines to stabilize reactive skin.

Key findings

  1. 01 Concentrations of 1-5% demonstrate significant increases in quercetin and total phenolics, leading to measurable anti-wrinkle effects via elastase inhibition.
  2. 02 In vitro tests at 100-200 μg/mL show over 95% superoxide anion inhibition, providing robust protection for fibroblasts against oxidative stress.

Due to the prestige of 'fermented' ingredients in K-beauty, this filtrate is frequently added at sub-clinical levels (<1%) for marketing claims. To achieve the documented antioxidant and anti-elastase benefits, it should be present as a primary liquid or at a minimum of 1%.

Stability

The filtrate is heat-stable up to 60°C and maintains integrity at room temperature. It is often co-processed with volcanic scoria to neutralize the characteristic pungent aroma of the fermentation process.
