ROSIN

Rosin is a brittle, faintly aromatic solid, which may be transparent or slightly translucent and possesses a glassy fracture. It is insoluble in water, but soluble in many organic solvents including alcohols, ethers and esters, and aliphatic, aromatic and chlorinated hydrocarbons.

 

Resin acid composition (%) of Pinus roxburghii rosin

S.NO COMPONENT MEAN RANGE
1. Isopimaric 20.9 19.5 – 23.1
2. Dihydroabietic 1.5 1.3 – 2.5
3. Abietic 37.5 35.5 – 39.4
4. Neoabietic 15.1 14.2 – 15.8
5. Piamaric 8.3 7.0 - 8.8
6. Levopimaric/palustric 13.5 11.2 – 15.7

                   All rosin is purchased on a colour basis, which varies from pale amber to black. The lighter the colour, the more valuable the rosin.

                 The procedure for sample and colour grading is fairly simple: a portion of rosin is formed into a cube of 7/8 inch(22mm) sides. This cube is placed inside the cabin of Lovibond Tintometer and Standard Colour of the specific grade is compared with that of the cube. The standard  colour is obtained by combination of glass slides of different shades  of Red, Blue and Yellow . This is as per the procedure laid down in IS 553:1984.
