Gum Rosin CAS NO: 8050-09-7

Gum Rosin is a solid form of resinobtained from pines and some other plants, mostly conifers, produced by heating fresh liquid resin to vaporize the volatile liquid terpene components. It is semi-transparent and varies in color from yellow to black. At room temperature rosin is brittle, but it melts at stove-top temperature. It chiefly consists of various resin acids, especially abietic acid.[1]The term "colophony" comes from colophonia resina, Latin for "resin from Colophon", an ancient Ionic city.
