    摘要: 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.

    摘要: A method for enhancing bleaching efficacy for treatment of articles, including for example laundry is disclosed. Methods for antimicrobial disinfecting and/or sanitizing and bleaching laundry and other articles is provided by washing the articles with a peroxyformic acid composition at a first pH for effective antimicrobial efficacy, thereafter applying an alkaline source to increase the pH for addition of a bleaching component. The methods can be provided as part of a laundry operation and can be utilized in industrial and commercial applications.
