20110094044 | PASTE-LIKE DETERGENT FORMULATION COMPRISING BRANCHED ALKOXYLATED FATTY ALCOHOLS AS NON-IONIC SURFACTANTS - The invention relates to a hydrous, paste-like cleaning or detergent composition comprising an emulsion having an aqueous phase and an oil phase, the composition comprises based on the whole concentrate 1 to 50 wt-% of one or more alkalinity source, 1 to 60 wt-% of a guerbet alcohol ethoxylate of the formula R | 04-28-2011 |
20120172439 | GENERATION OF PEROXYCARBOXYLIC ACIDS AT ALKALINE pH, AND THEIR USE AS TEXTILE BLEACHING AND ANTIMICROBIAL AGENTS - 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. | 07-05-2012 |
20120225943 | DETERGENTS CAPABLE OF CLEANING, BLEACHING, SANITIZING AND/OR DISINFECTING TEXTILES INCLUDING SULFOPEROXYCARBOXYLIC ACIDS - 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. | 09-06-2012 |
20130247308 | LAUNDRY DETERGENT COMPOSITION FOR LOW TEMPERATURE WASHING AND DISINFECTION - The invention relates to a low temperature detergent composition of a first component for cleaning and disinfecting comprising:
