Abstract: The need for a liquid detergent composition for washing dishes which provides effective removal of both crystalline and polymerised grease, while requiring less time and effort to clean and rinse the dishes, is met when the composition is formulated with a surfactant system having an anionic surfactant, a co-surfactant, and a non-alkoxylated esteramine.

Abstract: A detergent composition includes a detersive surfactant and a graft polymer.

Abstract: Methods and apparatus for estimating properties of a mixture of two or more surfactant species are provided. Multiple molecular dynamics simulations of the mixture are performed, each simulation using a particular total concentration of the surfactant species and a particular ratio of the surfactant species, such that the multiple simulations cover a plurality of such total concentrations and a plurality of such ratios, each simulation being carried out above the critical micelle concentration of the simulated mixture. For each simulation, and from the results of each simulation, a distribution of each surfactant species between at least a micellar pseudo-phase and a non-micellar pseudo-phase of the mixture at the particular total concentration and particular ratio for that simulation is determined.
