Detergency of commercial liquid detergents before and after modification with SB3C16 (5%, m/m) sulfobetaine (N-hexadecyl-N,N-dimethyl-3-ammonio-1-propanesulfonate) was examined using colorimetric analysis based on a CIELab system. The EMPA 101 standard cotton fabric soiled with carbon black and olive oil was used in washing tests under the following experimental conditions: the concentration of liquid laundry detergents 1.25–50 g/L, 30 min washing cycle, water hardness 5.35 mval/L, 40℃, 200 rpm. Results of physicochemical analysis of color, form, odor, pH, viscosity, density and content of anionic surfactants in detergents, as well as construction parameters of tested cotton fabrics, showed compliance with the requirements of standards and manufacturers’ declarations. The studies revealed that increasing the concentration of laundry detergent solutions caused a gradual increase in foaming power and detergency. Modification with SB3C16 positively improved washing ability and the maximum values were achieved at 23.7% (m-L1, 50 g/L) and 37% (m-L2, 40–45 g/L), respectively. Detergency efficiency was improved by 6.86% (m-L1) and 10.72% (m-L2) on average. EMPA 101 fabrics before and after washing were subjected to microscopic observations, which showed no serious damage to the fibers, but only slight loosening of individual fibers. In summary, the results clearly indicate that SB3C16 sulfobetaine favorably improves washing performance and can be successfully used in liquid laundry detergents due to its good surface properties.
