Japan wax (木蝋 Mokurō), also known as sumac wax, sumach wax, vegetable wax, China green tallow, and Japan tallow, is a pale-yellow, waxy, water-insoluble solid with a gummy feel, obtained from the berries of certain sumacs native to Japan and China, such as Toxicodendron vernicifluum (lacquer tree) and Toxicodendron succedaneum (Japanese wax tree).
[1] Japan wax is a byproduct of lacquer manufacture.
The fruits of the Toxicodendron trees are harvested, steamed, and pressed for the waxy substance which hardens when cool.
[1] Japan wax is sold in flat squares or disks and has a rancid odor.
Japan wax is used in candles, furniture polishes, floor waxes, wax matches, soaps, food packaging, pharmaceuticals, cosmetics, pastels, crayons, buffing compounds, metal lubricants, adhesives, thermoplastic resins, and as a substitute for beeswax.
