Japan wax

Japan wax 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 Rhus verniciflua (Japanese sumac tree) and R. succedanea (Japanese wax tree).

Japan wax is a byproduct of lacquer manufacture. It is not a true wax but a fat that contains 10-15% palmitin, stearin, and olein with about 1% japanic acid. Japan wax is sold in flat squares or disks and has a rancid odor. It is extracted by expression and heat, or by the action of solvents.


Japan wax is used chiefly in the manufacture of 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.
