Refined Castor Oil BSS Grade is a premium quality oil derived from refined commercial grade castor oil, following the British Standard Specifications (B.S.S). It is obtained by crushing steam-cooked castor seeds via an expeller and further processed through bleaching and filtering to reduce color intensity, free fatty acids, and moisture content. This pale yellow, viscous and clear liquid oil is non-edible and serves as an essential industrial ingredient primarily used in pharmaceutical and cosmetic formulations. It is notably utilized as a lubricant component in coating vitamin and mineral tablets, manufacture of polyurethane resins, hydraulic fluids for automotive and machinery applications, and in petroleum oil-field de-emulsification. With critical properties such as a ricinoleic acid content of minimum 85%, iodine value between 82-90, and specific gravity of 0.954-0.960 at 30°C, this refined castor oil offers consistent performance and high purity for demanding industrial uses.

Refined Castor Oil (British Standard Specifications-B.S.S)
Refined castor oil(RCO) is extracted from Refined Commercial Grade Castor Oil(CCO), that is produced by crushing the steam-cooked castor seeds of the expeller. RCO is used as an essential component that serves as a lubricant in vitamin and mineral tablet coatings and as a raw material for the manufacture of value-added castor oil derivatives.The CCO is processed by the bleaching and filtering method that helps to minimize the quality of colour, F.F.A.( Free Fatty Acid) and moisture.
