Soluble in ethanol, 5%～10% soluble in ether. Insoluble in water, but soluble in alkaline aqueous solution. There are two kinds of products: wax-containing products and dewaxed products. The resinous substance (called purple stalk) is secreted by the purple gum worm (Lacciferlacca), which is parasitic on leguminous or mulberry plants (such as Oxalis, Yangqing, Bubble fire rope, three-leaved bean, and more than 200 kinds of trees such as a big green tree).
