Abstract

The present invention relates to novel combined laundry detergent, bleach, and antimicrobial composition incorporating novel sulfoperoxycarboxylic acid compounds, and methods for making and using them. The sulfoperoxycarboxylic compounds used in compositions of the invention are storage stable, water soluble and have low to no odor. Compositions of the invention may be in the form of a liquid, a solid, or a gel. The sulfoperoxycarboxylic compounds useful in preparing compositions of the present invention can be formed from non-petroleum based renewable materials.
