A composition includes a C10 aliphatic branched chain alcohol ethoxylate; a C12 aliphatic straight chain alcohol ethoxylate, and a reactive builder. The composition effects an increase of at least about 30% in detergency measured as reflectance at 460 nanometers (nm) of a stained fabric at which the composition has been applied when compared to reflectance observed at 460 nm at the stained fabric prior to application of the composition. The stained fabric treated at which the composition has been applied exhibits a reflectance at 460 nm that is greater than the reflectance of the stained fabric at which a substantially similar composition has been applied. The substantially similar composition includes nonyl phenol ethoxylate.
