Galactarate based metal sequestration composition
A system and method for a metal sequestration composition comprising combining a galactaric salt or galactaric acid with a metalloid oxyanion, and an alkali compound. The system and method enable the production of a metal sequestration composition that either alone or in combination with other functional components (e.g. surfactants, solvents, pH modifiers) provide water treatment or cleaning compositions.
PRECURSOR POLYELECTROLYTE COMPLEXES COMPOSITIONS
The invention relates to compositions and methods of treatment employing compositions comprising polyelectrolyte complexes. The compositions include a water-soluble first polyelectrolyte bearing a net cationic charge or capable of developing a net cationic charge and a water-soluble second polyelectrolyte bearing a net anionic charge or capable of developing a net anionic charge. The total polyelectrolyte concentration of the first solution is at least 110 millimolar. The composition is free of coacervates, precipitates, latex particles, synthetic block copolymers, silicone copolymers, cross-linked poly(acrylic) and cross-linked water-soluble polyelectrolyte. The composition may be a concentrate, to be diluted prior to use to treat a surface.
SANITIZING AND DISINFECTING SUBSTRATES LOADED WITH HYPOCHLOROUS ACID SOLUTION
Sanitizing and disinfecting substrates of a nonwoven fabric material are loaded with an HOCl solution having a FAC concentration from about 25 ppm to about 750 ppm and a potential of hydrogen (pH) from about 4.5 pH to about 7.5 pH. The substrate may be a synthetic nonwoven fabric laminate having outer layers of one or more Spunbond synthetic fibers and an inner layer of polyester (PET) or pulp. Alternatively, the substrate may be an organic nonwoven fabric formed from one or more layers of cellulosic fibers. The layers may be bonded together by adhesive bonding, chemical bonding or thermal bonding. The substrates may be disposed within a container for storing and subsequently dispensing the substrates. The substrates may be pre-moistened and disposed within the container, or alternatively, disposed within the container and subsequently moistened with the HOCl solution.
ANHYDROUS AUTODISH FORMULATION
A method of washing glassware is provided including: providing automatic dishwashing apparatus; providing soiled glassware; placing soiled glassware in automatic dishwashing apparatus; providing wash water; providing rinse water; selecting anhydrous mixed powder or mixed granule comprising: 2.5-5 wt % of oxidized maltodextrin, wherein oxidized maltodextrin has Degree of Oxidation of 0.4-1.7; 10-25 wt % of amino acid based builder; 20-75 wt % of additional builder, wherein additional builder includes at least one of sodium citrate, sodium carbonate and sodium percarbonate; 2.5-7.5 wt % of bleach activator; 0.5-10 wt % of nonionic surfactant; 0.5-1 wt % of phosphonate; 1-6 wt % of enzyme; 5-15 wt % of filler; and <1 wt % water; placing selected anhydrous mixed powder or mixed granule in automatic dishwashing apparatus; contacting selected anhydrous mixed powder or mixed granule with wash water to form combination; contacting soiled glassware with combination to provide treated glassware; and then contacting treated glassware with rinse water to provide cleaned glassware.
CLEANING COMPOSITIONS AND THEIR USE
The present invention is directed towards cleaning compositions containing (A) at least one chelating agent selected from alkali metal salts of methyl glycine diacetic acid (MGDA) and of glutamic acid diacetic acid (GLDA) and of citric acid, (B) an alkali metal salt of glycine or alanine,
in a weight ratio of (A):(B) of from 10:1 to 1:10.
Tetraacetyldiamine and triacetyldiamine derivatives useful as bleach activators
This disclosure relates generally to bleach activator compositions. This disclosure relates more particularly to tetraacetyldiamine and/or triacetyldiamine derivatives and compositions thereof and to their use as bleach activators, and methods for using them as detergents or biocides.
Surfactants for cleaning products
The present disclosure pertains to surfactants for use in the formulation of detergents, foaming agents, emulsifiers, and degreasers. Some aspects of the invention include formulations suitable for cleaning and/or condition fabrics including upholstery. Some formulations are suitable for in home or commercial dry cleaning. Some of the formulations may be suitable for cleaning hard surfaces including plastic surfaces.
Chlorine dioxide disinfecting cloth
The invention relates to highly effective disinfecting or sterilising cloths with chlorine dioxide as the main active ingredient. For this, the chlorine dioxide is only generated shortly before use by bringing a cloth impregnated with a chlorite or chlorate salt in contact with a clearly defined amount of a suitable activation agent that is fluid or dissolved or admixed in a fluid, and prepackaged as a single dose, for the generation of chlorine dioxide. In a preferred embodiment, the impregnated cloth and the activation fluid are packaged in a common packaging unit and the activation occurs by breaking through a barrier separating the cloth or the cloths and the activation fluid. In a further preferred embodiment, the packaging is a moulded part having two packaging spaces separated from one another by removable barriers, which can be converted into a moulded part with only one chamber via simple pressure in one direction. The activation fluid or the disinfecting cloth can contain further substances, such as the pH-value-controlling substances, surfactants, guanidine derivatives, aldehydes, phenoxyethanols, phosphate esters, alcohols, sulfoxides, etc. Preferably, the disinfecting cloth according to the invention is used for disinfecting and/or sterilising medical instruments and/or medical products and/or surfaces.
