A Novel Short Oil Alkyd Resin Based on Coconut Oil and Rosin for Detergent Compositions

Alkyd resin is normal raw material for paints, printing inks, and water thinable coatings. In the present work, we have successfully prepared a very short oil alkyd using high proportion of rosin, the other ingredient are coconut oil, maleic anhydride and glycerol. Various parameters like temp., time of heating and mole ratio have been studied. All the sample have been analyzed for physiochemical characteristics like acid value saponification Value, HLB ratio, viscosity, and cleaning performance on soil cloth. Two samples AR-1, AR-2, have given good result so these samples have been used after neutralization with KOH in powder detergent and liquid detergent compositions. These polymer are based on vegetable origin like coconut oil, glycerol and rosin. The above result indicates that novel short oil alkyd can be used as replacement of crude petroleum based acid slurry and Alpha Olefin Sulphonate. The use of coconut oil and rosin gives good foaming and cleaning properties. The price of this material is slightly lower than conventional petroleum based actives. This product will also support green chemistry as the raw materials are of vegetable origin.
