English Name:Rice Yeast Ferment Filtrate
INCI Name:Rice Ferment Filtrate (and) Yeast Extract
Raw Material Source
Selected high-quality rice (Oryza sativa) is used as the fermentation substrate.
Fermentation Strain:A highly efficient yeast strain (such as Saccharomyces cerevisiae) is cultivated through a liquid
fermentation process.
Fermentation Process: Under controlled temperature, pH, and dissolved oxygen conditions, the yeast decomposes
starch and proteins in rice to generate various
small-molecule metabolites.
Appearance: Colorless to pale yellow transparent liquid
Odor:Mild fermentation aroma
PH:5.0–6.0
Solubility:Easily soluble in water
Stability:Stable under heat (<80°C) and pH 4–8 conditions
Main Functions：
Moisturizing & Repairing
Small-molecule amino acids and peptides deeply hydrate the skin, repair the skin barrier, and enhance moisture retention.
Whitening & Brightening
Fermentation products inhibit tyrosinase activity, promote keratin renewal, and help achieve a more even and radiant
complexion.
Antioxidant & Anti-aging
Contains yeast β-glucan and antioxidant peptides that effectively scavenge free radicals and slow down skin aging.
Soothing & Calming
Organic acids and B vitamins improve microcirculation, relieving skin sensitivity and dryness.
Barrier Strengthening
Enhances water and lipid balance in the stratum corneum, reinforcing the skin’s natural defense system.
Application Fields
Toners / Serums / Creams
Masks / Mists / Cleansers
Scalp care products (promoting scalp microecological balance)
Recommended Dosage
In cosmetics: 1% – 10% (adjust based on product positioning)
Product Advantages
Naturally sourced and sustainable, in line with Clean Beauty principles
High bioactivity, superior to non-fermented rice extracts
