Ingredient profile
Sasa veitchii extract is produced by water or hydro-alcoholic extraction of the leaves of Sasa veitchii. The extract contains polysaccharides, chlorophyllin, and flavonoid compounds. Concentrated preparations are also sometimes sold as a separate ingredient.
Related species including Sasa albomarginata are sometimes used interchangeably in cosmetic contexts; the specific species should be verified on the ingredient specification sheet.
OEM applications
In Japanese cosmetics, kumazasa extract appears in oral-care products (mouthwash, toothpaste), body washes, face masks, and scalp lotions. The ingredient is frequently associated with "cleansing" and freshness positioning.
As a food-contact material, fresh kumazasa leaves are used to wrap rice confections and preserved foods — an entirely separate use under food safety regulation.

FAQ for OEM buyers
Q. What is the correct INCI name for kumazasa extract?
CosIng lists both 'Sasa Veitchii Extract' and 'Sasa Albomarginata Leaf Extract' as accepted INCI names; the choice depends on supplier specification and source botanical. Confirm the precise INCI name with the supplier-supplied specification before printing label artwork.

Q. Is kumazasa extract used as a natural preservative in finished cosmetics?
Some suppliers position kumazasa extract as a preservation-support ingredient based on traditional food-wrap antimicrobial lore, but it is not a recognized cosmetic preservative under 厚生労働省 (Ministry of Health, Labour and Welfare) Standards for Cosmetics Annex 3. Any product relying on kumazasa for preservation must still pass standard challenge testing with a recognized preservation system.

Q. Can the same kumazasa extract be cross-sold for food and cosmetic use?
Food-grade and cosmetic-grade specifications differ in process, residual-solvent, and microbial limits. Buyers should request a cosmetic-grade COA and confirm regulatory compliance (PMD Act for cosmetics, Food Sanitation Act for food) separately.
