It is called CNSL, which is pericarp fluid of the cashewnut.The characteristics of CNSL is governed by IS 840. The specification of CNSL is as follows: Specific gravity 30/30°C 0.950 to 0.970 Viscosity at 30°C, in centipoises 300 (max) Moisture, % by weight, Max 1.0 Loss in weight on heating, Max 2.0 Ash, % by weight, Max 1.0 iodine value,a) Wij's method - 250b) RK method - 290 Polymerization time in min, Max 4 CNSL is also used in the production of Cardanol and Card phenol, which are widely used aromatic hydrocarbons.
