  • Patent number: 8729296
    Abstract: The present disclosure provides methods for generating percarboxylic acid compositions and/or peroxycarboxylic acid compositions formed external to a point of use in non-equilibrium reactions for use in certain bleaching and antimicrobial applications, in particular laundry applications. The compositions are generated external to a point of use, at alkaline pH levels, viz. greater than about pH 12, and optionally suitable for use with detergents and/or surfactants for synergistic bleaching efficacy. Methods of bleaching and/or disinfecting are further provided.
    Type: Grant

  • Publication number: 20130247308
    Abstract: The invention relates to a low temperature detergent composition of a first component for cleaning and disinfecting comprising: (a) about ?2 wt.-% to about ?50 wt.-% of a nonionic low alkoxylated alcohol tenside containing 1 to 2 alkylene oxide units; (b) about ?0 wt.-% to about ?60 wt.-% of nonionic higher alkoxylated alcohol tenside containing 3 to 40 alkylene oxide units; (c) about ?1 wt.-% to about ?60 wt.-% of a source of alkalinity; (d) about ?0 wt.-% to about ?95 wt.-% of at least one solvent; calculated on the total weight amount of the detergent composition of the first component. The invention relates further to a low temperature detergent composition for cleaning and disinfecting of a first component composition and a second component composition containing at least one bleaching agent.
