Ingredient profile
Eriobotrya japonica leaf extract is produced by water, hydro-alcoholic, or glycol extraction of dried loquat leaves. The extract contains triterpenoid saponins, tannins, flavonoids, and amygdalin-family compounds in trace amounts.
Cosmetic-grade preparations focus on the water-soluble fractions, with traditional preparation methods typically requiring longer extraction times and specific drying protocols.
OEM applications
In Japanese cosmetics, biwa leaf extract appears in face toners, essences, sensitive-skin lines, and scalp-care products. Some traditional-therapy-adjacent products (biwa-leaf hot compress kits, biwa leaf bath additives) are marketed under non-cosmetic positioning.
The ingredient pairs frequently with other traditionally-used botanicals such as dokudami and yomogi in heritage-positioning Japanese skincare.

FAQ for OEM buyers
Q. Is Eriobotrya Japonica Leaf Extract listed in CosIng?
Yes, 'Eriobotrya Japonica Leaf Extract' is listed in the CosIng database as a skin-conditioning ingredient. It is widely used in Japan, Korea, and China as a heritage botanical in cosmetics.

Q. Can biwa-leaf hot-compress kits or biwa-leaf bath kits be sold as cosmetics?
Hot-compress / biwa-leaf moxibustion-style products often fall outside cosmetic regulation entirely (they are sold as miscellaneous goods or traditional remedies), and product positioning needs to be aligned with the regulatory category at registration. Cosmetic-registered biwa products are specifically the leaf-extract-containing topical formulations.

Q. What active constituents drive supplier marketing for biwa leaf extract?
Suppliers commonly highlight triterpenes (ursolic acid, oleanolic acid) and tannins as marker compounds in biwa leaf extracts; specific actives lists should be requested from the supplier with COA. Cosmetic claims must stay within general cosmetic-claim ranges regardless of the actives narrative.
Sources · Last reviewed: 2026-04-26
- PubChem — Ursolic acid (CID 64945)
Q. Are there cyanogenic-glycoside concerns since the loquat seed contains amygdalin?
Amygdalin is concentrated in the seed (not the leaf), so leaf-derived cosmetic extracts are not commonly associated with cyanogenic-glycoside exposure. Buyers should still request a residual-toxin / heavy metal COA from the supplier for due-diligence documentation.
