Abstract
Applicants have developed a physically and chemically stable solid composition containing a soil release polymer and an acidulant. The sour step thus accomplishes both stain removal and residual alkalinity removal. A novel method of using a soil release polymer and an acidulant together in the same post wash step of a laundry wash process is also disclosed. The solid composition is physically stable, even during aqueous dispensing, i.e. non-slumping and non-weeping. The solid could be formed through a melt, cast, or pressed process.
