Abstract

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.

Abstract

Malenized linseed oil suitable for use in liquid detergent has been synthesized. The reaction conditions such as mole ratio, temperature, time of reaction and use of catalyst have been standardized to get a product with desired HLB ratio, viscosity and solubility. A standard liquid detergent mainly based on sodium laurel sulphate, sodium laurels ether sulphate, Acid slurry and Alpha olefin sulphonate has been prepared, in successive compositions acid slurry and alpha olefin sulphonate has been replaced by neutralized malenized linseed oil by 50 to 100 per cent. A comparison of our maleic based detergents with commercial samples shows that maleic treated oils give excellent foaming, surface tension reduction and detergency properties. The raw material cost of our novel liquid detergents in reasonable and they can be tried on pilot scale and commercial scale production. The special feature of these liquid detergents is freedom from conventional linear alkyl benzene sulphonate and sodium tripoly phosphate so they can be labelled as ecofriendly products for green environment.
