Sacchromyces/Xylinium/Black Tea Ferment (Kombucha Ferment)
What is Sacchromyces/Xylinium/Black Tea Ferment (Kombucha Ferment)?
Sacchromyces/Xylinium/Black Tea Ferment, also known as Kombucha Ferment, arises from the controlled fermentation of black tea using specific microorganisms: Saccharomyces yeasts and Xylinum bacteria (Komagataeibacter xylinus). This process yields a filtrate rich in microbial cellulose, organic acids, polyphenols, and enzymes. In cosmetics, it falls under skin conditioning agents and humectants. It functions by forming a lightweight film on the skin to lock in moisture, deliver antioxidants from tea fermentation, and support the skin's barrier with polysaccharides. The non-living filtrate integrates into creams, serums, and masks to enhance texture and feel without heaviness. Derived traditionally from kombucha culture but optimized for skincare stability, it offers gentle, multi-tasking performance across formulations.
