  • Patent number: 8349788
    Abstract: This invention discovers that laundry-strength hypochlorite bleach compositions are described by three essential components; hypochlorite, hydroxide, and the concentration ratio (CR), the latter defined as the concentration of hypochlorite over the concentration of hydroxide (also, its reciprocal). The hypochlorite content determines fabric cleaning efficacy, the hydroxide content determines stability, and the CR indicates quality of fabric safety, such quality ranging from damaging to gentle. Therefore, hypochlorite bleach compositions can range from fabric damaging to degrees of fabric protection, depending upon the values of CR. Values of CR (as defined) greater than 30:1 characterize fabric-damaging common regular bleach. By decreasing the ratio value, fabric protection progressively improves to a relatively broad maximum at a ratio value about 2:1.

    Abstract: The present invention relates to a liquid detergent composition comprising enzymes and a boron derived enzyme stabilising agent which can be used as a cleaning and softening composition in domestic laundry processes and which further comprises diester or diamide quaternary ammonium compound, preferably a diester quaternary ammonium compound. Preferably the composition has a pH which is between 7 and 10, more preferably between 7.5 and 8.5 when diluted to a 1% solution in distilled water. Whilst the composition may be used directly in the form of a liquid, or may be predissolved in water, in a preferred execution of the present invention the composition is used in the form of a foam or a gel or paste.

  • Patent number: 6228827
    Abstract: The invention relates to the use of mutated protease of the subtilisin type which carries at least one mutation in its amino acid sequence, leading to a reduced positive charge or an increased negative charge in the substrate binding region of the molecule, in liquid to gel-form laundry detergents. This protease shows increased stability above all in detergents such as these.

  • Patent number: 5741768
    Abstract: Improved separation of emulsified hydrophobic organic soils can be obtained from aqueous effluents using an amphoteric dicarboxylate surfactant material in combination with cationic destabilizer or floeculent materials. Such a treatment in combination with an acidic pH adjustment causes the rapid separation of hydrophobic organic soils from the aqueous stream, the treated aqueous stream is environmentally compatible.Improved laundry detergents comprising an organic amphoteric carboxylate surfactant and selected nonionic surfactants provide both cleaning for fiber and fabric containing items soiled with substantial quantities of hydrophobic soil. The pH of an effluent generated in such cleaning processes can be adjusted to an acid pH and treated with a cationic material causing a break that permits rapid and substantially complete separation of the hydrophobic organic soils from the effluent. Residual concentrations of organic soil in effluent water can be less than 250 ppm and can be as low as 10 ppm.
