Abstract
Standard heavy duty household laundering formulations were prepared from a series of well-characterized sucrose ester surfactants. The detergency and redeposition performance of these formulations was measured by the soil accumulation method, using for comparison standard formulations based on sulfated and sulfonated surfactants. Also measured were the lime soap dispersing power, and the tendency to leave residual adsorbed deposits on the fabric. The sucrose ester series as a whole performed at least as well in detergency as the standard anionics, and retained their effectiveness at lower concentrations. They showed about the same, or slightly less, tendency than the anionic controls to build up organic residues on the fabric, both series being much superior to soap in this respect. In redeposition performance and lime soap dispersion the sucrose esters were outstandingly better than any of the standard anionic controls. Within the sucrose ester series, the C18 esters gave generally better performance than the shorter chain esters, and the saturated esters tended to be better than the unsaturated.
