Glycerol ester of wood rosin (or gum rosin), also known as glyceryl abietate or ester gum, is an oil-soluble food additive (E number E445). The food-grade material is used in foods, beverages, and cosmetics to keep oils in suspension in water, [ 2 ] and its name may be shortened in the ingredient list as glycerol ester of rosin .

Rosin (/ ˈ r ɒ z ɪ n /), also known as colophony or Greek pitch (Latin: pix graeca), is a resinous material obtained from pine trees and other plants, mostly conifers.The primary components of rosin are diterpenoids, i.e., C 20 carboxylic acids.
Gummo-oleoresins (oleo-gum resins, gum resins) occur mostly as crude balsams and contain also water-soluble gums. Processing of oleoresins is conducted on a large scale, especially in China (400,000 tons per year in the 1990s), but the technology is too labor-intensive to be viable in countries with high labor costs, such as the US.
Many different kinds of resins may be used to create a varnish. Natural resins used for varnish include amber, kauri gum, dammar, copal, rosin (colophony or pine resin), sandarac, balsam, elemi, mastic, and shellac. Varnish may also be created from synthetic resins such as acrylic, alkyd, or polyurethane. A varnish formula might not contain any ...
Rosin is insoluble in water, mostly soluble in alcohol, essential oils, ether, and hot fatty oils. Rosin softens and melts when heated and burns with a bright but smoky flame. Rosin consists of a complex mixture of different substances including organic acids named the resin acids. Related to the terpenes, resin acid is oxidized terpenes.
Zallen tells in detail how turpentine (and rosin) are produced as naval stores. [4] Pine trees especially in North Carolina were tapped for sap which was doubly distilled to make turpentine and rosin (aka resin)–hence the name tar heels. The trees were scored with a ledge called a “box” to collect the sap.
