Gum rosin is an organic compound of monoterpene, turpentine and resin acid. Monoterpene is compounded by α-Pinene, β-pinene, camphene, myrcene, carene, dipentene, β-Phellandrene and other monoterpenes. Resin acid is compounded by levopimaric acid, palustric acid, abietic acid, neoabietic aicd, dehydroabietic acid, pimaric acid, isopimaric acid, sandaracopimaric acid, dicarboxylic acid and abietic type acid.As you can see, it is the composition of many substances. In the mill you will not receive the nanoparticles. The composition will be warmed up and stick. Try first to crumble, then add the crumbles in alkaline solution. Of the acids and alkali are formed soaps that perform the role of nanoparticles stabilizers when ultrasonic dispersion..
