Development of Fatliquor (surfactant) from Castor oil/rubber seed oil blends

Abstract

Castro ( Ricinus communis) oil was sulphated at 10⁰ C and 25^OC. Blends of castor oil and rubberseed ( Hevea braziliensis) oil mixed in three different ratios were sulfated at 25⁰C. Castor oil sulphated at 25⁰C was found to incorporate a greater amount of surface active (SO₄²⁻) group than the same oil showed the best potential in terms of appearance of the product and stability of its oil-in-water (o/w) emulsion.The other two blends (containing 33.3% and 25% castor oil ) also showed adequate stability. Each of the blends incorporated higher surface active (SO₄²⁻) group than the unblended castor oil. This trend appeared to increase with the proportion of rubber-seed oil in the fatliquors.
