Product Description
Rosin is the resinous constituent of the oleo-resin exuded by various species of pine, known in commerce as crude turpentine. The separation of the oleo-resin into the essential oil (spirit of turpentine) and common rosin is accomplished by distillation in large copper stills. The essential oil is carried off at a temperature of between 100° and 160°C, leaving fluid rosin, which is run off through a tap at the bottom of the still, and purified by passing through straining wadding.

Rosin is the resinous constituent of the oleo-resin exuded by various species of pine, known in commerce as crude turpentine.

The essential oil is carried off at a temperature of between 100° and 160°C, leaving fluid rosin, which is run off through a tap at the bottom of the still, and purified by passing through straining wadding.
Rosin varies in color, according to the age of the tree from which the turpentine is drawn and the degree of heat applied in distillation,from an opaque, almost pitch-black substance through grades of brown and yellow to an almost perfectly tran***rent colorless glassy mass.
Rosin is a solid form of resin obtained from pines and some other plants, mostly conifers, produced by heating fresh liquid resin to vaporize the volatile liquid terpene components. It is semi-tran***rent and varies in color from yellow to black.
Rosin is an ingredient in printing inks, photocopying and laser printing paper, varnishes, adhesives (glues), soap, paper sizing, soda, soldering fluxes, and sealing wax.
Rosin can be used as a glazing agent in medicines and chewing gum. It is denoted by E number E915. A related glycerol ester (E445) can be used as an emulsifier in soft drinks. In pharmaceuticals, rosin forms an ingredient in several plasters and ointments.
In industry, rosin is a flux used in soldering. The lead-tin solde |
