Morus Bombycis (Kuwa) Leaf Extract
What is Morus Bombycis (Kuwa) Leaf Extract?
Morus bombycis, commonly known as Kuwa or Japanese mulberry, is a deciduous tree native to East Asia. Its leaf extract is derived from the fresh or dried leaves through solvent extraction or other botanical processing methods. Chemically, it contains flavonoids, phenolic compounds, and polysaccharides characteristic of Moraceae family plants. In cosmetics, it serves as a skin conditioning-miscellaneous agent, primarily incorporated into leave-on products like creams, lotions, and serums. It functions by forming a lightweight film on the skin surface or interacting with the stratum corneum to reduce roughness, minimize friction, and promote a smoother tactile feel through its emollient-like properties from natural polymers and humectants.
