Rosin is a type of oleoresin in the pine family、 mainly composed of C19H29COOH. There are three types of rosin: resin rosin、 wood rosin、 and floating oil rosin. It is often used as a depilatory agent by poultry slaughterers. Rosin itself is not very toxic to the human body、 but it often contains heavy metals such as lead and toxic compounds. In addition、 the industry is greedy for low-cost repeated use、 and the peroxide generated after rosin oxidation seriously affects human health、 making it a regulated product. Rosin can be obtained from pine like tree species around the world、 especially Pinus palustris、 Pinus caribaea、 and Pinus taeda、 which are found in the southeastern United States. Cut holes in these tree bodies to distill and extract high viscosity secretions called gum thus. This volatile liquid is turpentine; The remaining hard resin is called rosin. Although rosin、 as a component of any polish and pigment、 is not satisfactory、 it has been used as a dopant for polish and pigment due to its being one of the cheapest raw materials. In addition、 rosin has many other uses in the field of art、 such as bonding、 sealing、 and other mechanical effects. Rosin was also known as colophony and Greek pitch
