Abstract
Cleaning compositions containing a lime-soap dispersant and a method of preparing liquid cleaning compositions containing lime-soap dispersants are disclosed. More specifically, cleaning compositions containing lime-soap dispersant polymers derived from maleic acid, maleic anhydride, or salts thereof, copolymerized with a hydrophobic monomer containing from 4 to 20 carbon atoms are disclosed. Cleaning compositions containing a lime-soap dispersant based on maleic acid/diisobutylene polymers are particulary effective in producing stable liquid cleaning compositions with good lime-soap dispersancy properties.
