BACILLUS/LACTOBACILLUS/STEVIA REBAUDIANA STALK EXTRACT FERMENT FILTRATE.

Valuable CAS - / HUMECTANT

A sophisticated biotechnological ferment derived from Stevia stalks that utilizes double-strain fermentation to unlock bioavailable metabolites. This nutrient-dense filtrate serves as a multifunctional powerhouse, targeting both deep hydration and the structural preservation of skin proteins.

Science

This ingredient operates via a triple-action pathway: it delivers fermented organic acids (like lactic acid) and amino acids to reinforce the skin's Natural Moisturizing Factor (NMF); it utilizes concentrated diterpenes and flavonoids to neutralize oxidative stress; and most significantly, it acts as an anti-glycation agent to prevent sugar molecules from cross-linking with collagen fibers.

Key findings

  1. 01 In vivo testing at 2% concentration demonstrated a statistically significant reduction in epidermal scaling and a marked improvement in moisture retention over a 28-day period.
  2. 02 In vitro analysis confirms that concentrations between 1-3% effectively inhibit the formation of Advanced Glycation End-products (AGEs), helping to maintain dermal elasticity.

Because it is a fermented extract often marketed under the 'probiotic' trend, many brands include it at decorative levels (below 0.5%) to claim benefits. At Moumoujus, we recognize that the anti-glycation and clinical hydration benefits require a minimum threshold of 1% to be biologically active.

Stability

Excellent stability in aqueous systems; however, the natural pale yellow hue and subtle fermentation aroma should be accounted for in fragrance-free formulations.

Synergies

  • Hyaluronic Acid
  • Peptides
  • Niacinamide

Conflicts

  • Strong oxidizing agents
  • Formulations with pH above 8.0

Safety

Safe
Sensitization risk Low

While the specific INCI is awaiting formal CIR review, the precursor Stevia extracts and the Bacillus/Lactobacillus fermentation processes are globally recognized as safe and are widely used in both topical and food-grade applications.
