Ecofriendly Liquid Detergents Based on Malenised Vegetables Oils

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and Alpha olefin sulphonate has been prepared, in successive compositions acid slurry and alpha olefin sulphonate has been replaced by neutralized malenized linseed oil by 50 to 100 per cent.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.
