About BACILLUS/CAMELLIA JAPONICA SEED/SOYBEAN FERMENT EXTRACT

A fermented extract of Japanese camellia seeds and soybeans using Bacillus microorganisms, yielding an ingredient rich in saponins, isoflavones, and skin-conditioning compounds.

Detailed Analysis

Bacillus subtilis (the primary organism used, specified in cosing_description) ferments Camellia japonica seed oil and Glycine max (soybean). Bacillus ferments are widely used in Asian cosmetic traditions (e.g., fermented soybean natto). Camellia oil (Tsubaki oil) is similar to tea seed oil and contains oleic acid and saponins. Soybean provides isoflavones and proteins. Soy is a known food allergen but topical sensitisation is rare. No EU restrictions on Camellia japonica or soybean extracts in cosmetics; both appear in CosIng with 'SKIN CONDITIONING' functions.

Skin Benefits

  • ✓ Saponins from camellia provide gentle cleansing and anti-inflammatory action
  • ✓ Soy isoflavones (genistein, daidzein) offer antioxidant and phytoestrogenic support
  • ✓ Fermentation increases isoflavone bioavailability through glycoside hydrolysis

Known Concerns

  • ⚠ Soy is a recognised food allergen — trace topical sensitisation possible but uncommon
  • ⚠ Bacillus spores in raw ferment may be a concern for immunocompromised individuals
