Kumazasa extract is used in cosmetics and in oral-care products.

What it is
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.
Typical uses in Japanese products
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.
