Rosin Chemistry

Rosin is brittle and friable, with a faint piney odor. It is typically a glassy solid, though some rosins will form crystals, especially when brought into solution. Rosin mainly consists of different resin acids, especially abietic acid with general formula of C20H30O2


Insoluble in water; freely soluble in alcohol, benzene, ether, chloroform, glacial acetic acid, oils, carbon disulfide, dilute solutions of fixed alkali hydroxides. Low toxicity. Hard and friable at room temperature; soft and very sticky when warm. Combustible.

Chief constituents: Resin acids of the abietic and pimaric types, having the general formula of C20H30O2 , and having phenanthrene nucleus.

Melting and Flammability:

The practical melting point varies with different specimens, some being semi-fluid at the temperature of boiling water, others melting at 100C to 150C. It is very flammable (Flashpoint 187C), burning with a smoky flame, so care should be taken when melting it.

Rosin Salts:

Rosin combines with caustic alkalis to form salts (rosinates or pinates) that are known as rosin soaps.
