Black Tea Ferment (Saccharomyces/Xylinum/Black Tea Ferment) — liquid, Korea · Japan — MakeYourSkin

About this material

Black Tea Ferment (Saccharomyces/Xylinum/Black Tea Ferment) is a Kombucha-style ferment supplied by MakeYourSkin as filtrate / lysate / extract / powder depending grade for professional cosmetic formulation. Used across both Korean and Japanese beauty formulation, it is valued for skin conditioning, hydration, microbiome-friendly positioning.

What is Black Tea Ferment?

Black Tea Ferment is supplied under the INCI / technical name Saccharomyces/Xylinum/Black Tea Ferment.

It belongs to the Kombucha-style ferment group and is derived from microbial fermentation. The material reaches you as filtrate / lysate / extract / powder depending grade. It sits in the high-growth band of the 2025–2026 market, which means supply, pricing and claim substantiation are all moving quickly — confirm current availability before committing to a launch date.

Key Properties & Benefits

  • Skin conditioning
  • Hydration
  • Microbiome-friendly positioning
  • Produced by a controlled fermentation process with a defined organism and substrate.

Uses & Applications

Black Tea Ferment is used in essences, first-treatment toners, ampoules, sheet masks and fermentation-positioned moisturisers.

Typical applications from the catalogue record: Essences, toners, serums, masks, scalp.

In leave-on skincare it is normally dosed into a serum, ampoule or moisturiser where contact time is long enough for the claim to hold up. In rinse-off formats it is used at a lower level for label presence and sensory contribution rather than measurable performance. In Korean and Japanese formats it suits essences, toner pads, sheet-mask serums and lightweight gel-creams, where thin, layerable textures are the norm.

How to Use — Recommended Use Level

Typical use level 1–10% of the supplied filtrate
Recommended pH 4.0–6.5
Addition phase Water phase, cool-down
Solubility Water-soluble. Disperse into the water phase with stirring; avoid prolonged high heat where the material is heat-sensitive.

General rule: always begin at the lower end of the range, confirm the level against the supplier technical data sheet, and validate stability, pH, colour, odour and preservative efficacy on the finished formulation before scaling up.

Regulatory Note

Ferment filtrates and lysates require a defined substrate, organism, process and inactivation step, plus a microbiological specification and the preservative system used in the material itself. Confirm the exact INCI and that the organism is acceptable in the destination market.

Supplier diligence required: Exact INCI and preservative system supplier-dependent.

Sold as a cosmetic raw material for professional formulation. A published INCI name does not by itself authorise use: the buyer is responsible for confirming permitted status, maximum concentration, restrictions by product type, labelling and claim rules in every market the finished product is sold in. In India, cosmetics fall under the Drugs and Cosmetics Act 1940 and the Cosmetics Rules 2020 administered by CDSCO, with BIS standards (including IS 4707 Part 2) listing restricted substances. The EU applies Regulation (EC) No 1223/2009 and its Annexes; the United States applies the FD&C Act as amended by MoCRA; Korea, Japan and China operate their own positive lists and functional-cosmetic frameworks. Every finished product needs its own safety assessment.

Disclaimer & Caution in Use

For external cosmetic use in professionally formulated products only. This is a concentrated raw material, not a finished cosmetic, and it is not intended for undiluted application to skin, for ingestion, or for any medicinal purpose. Wear gloves and eye protection when handling, avoid raising dust with powders, and keep out of reach of children and pets. Always run a patch test on the finished formulation, and validate stability, compatibility, pH and preservative efficacy before sale. Information supplied is offered in good faith as formulation guidance and does not constitute a safety assessment, a regulatory approval or a medical claim.

Fine powder — avoid generating and inhaling dust. Use local exhaust ventilation or a suitable respirator when weighing, and wet the powder into the formulation phase rather than dry-blending in open air.

Heat-sensitive. Add at cool-down below the temperature stated on the technical data sheet; exceeding it degrades the active and can change colour and odour.

How to work with it

1 Check the phase before you weigh

The specification's Add at row is the one to read first. Water-phase materials added to a hot oil phase are the most common reason a batch separates.

2 Hold the pH inside the stated range

Measure the finished product, not the premix. Outside the range the activity drops away and, for some materials, the degradation route is what causes complaints.

3 Start at the bottom of the use level

Then work up through stability and compatibility testing. Higher is not better, and the destination market's limit may sit below your formulation ceiling.
