摘要： Coalescence of oil droplets during the dishwashing process can be significantly retarded, without detriment to the spontaneous grease removal properties of the formulation, by the presence of selected polymers having a hydrophilic backbone and hydrophobic side chains. The present invention provides a non-lamellar, unbuilt, aqueous, light duty cleaning composition comprising: a) 2-70 wt.% of surfactant selected from the group comprising: nonionic surfactant, a complex of anionic surfactant and zwitterionic surfactant, a complex of anionic surfactant and amphoteric surfactant and mixtures thereof, and, b) 0.02-7 wt.% of a polymer, said polymer comprising a negatively charged or neutral hydrophilic backbone with at least one hydrophobic and oil-soluble side chain wherein the ratio of polymer to surfactant falls in the range to 1:100-1:10. The invention also provides a process which comprises the step of treating the surfaces of the dishes with a composition as described. It is believed that the oil-soluble hydrophobic side chains of the polymer partition into oil droplets, while the hydrophilic backbone remains in the waterphase to stabilise the droplets against coalescence through a combination of steric hindrance and electrostatic repulsion.
