Performance & Formulation Insights for FermentEx Quillaja Saponaria

How Bio-Fermentation Unlocks Scalp & Skin Health

FermentEx Quillaja Saponaria leverages a dual-action mechanism powered by biotechnology. First, Lactobacillus bacteria ferment Quillaja Saponaria (Soapbark) extract. This process breaks down the plant material, increasing the bioavailability of its natural saponins—gentle cleansing agents that lift away excess sebum and impurities without stripping the skin’s protective barrier. Second, the fermentation creates a nutrient-rich postbiotic broth, Lactobacillus Ferment. This postbiotic helps to balance the skin and scalp’s natural microbiome, creating an environment where beneficial bacteria can thrive. This microbial harmony is key to its “non-active” anti-dandruff effect, as it addresses the underlying cause of flakiness and irritation rather than simply treating the symptoms.

Formulation Guidelines for Optimal Performance

This water-soluble active is easy to incorporate into a wide range of formulas. For optimal stability of the fermented components, add FermentEx Quillaja Saponaria during the cool-down phase of your formulation, at temperatures below 40°C (104°F). It performs best in a pH range of 4.0 to 7.0, making it compatible with most skin and hair care products. At a recommended usage rate of 1–5%, it functions as a potent scalp treatment and skin conditioner. It is highly compatible with common surfactants, conditioning agents, and other cosmetic actives.
