Percarboxylic Acid Component, Or Salt Thereof Patents (Class 510/310)
  • Patent number: 7326674
    Abstract: New cleaning compositions and methods of forming and using those compositions are provided. In a preferred embodiment, the compositions are in tablet form, with the tablets being dissolvable in water at the point-of-use for ease of storing and shipping. The compositions comprise sodium bicarbonate, citric acid, an alkali metal alkylbenzene sulfonate, an ingredient selected from the group consisting of a trialkyl glycol monoalkyl ether, limonene, and mixtures thereof, and other ingredients depending upon the embodiment. The diluted cleaner has a very low impact on the environment due to the low levels of surfactants in the diluted solution. Furthermore, the cleaning solution performs well on protein stains due to the production of CO2 and the presence of sodium perborate. The inventive composition can be used on a wide range of substrates, from hard surfaces to fabrics.

  • Patent number: 7008913
    Abstract: Disclosed is a process for the treatment of a plant gaseous stream containing odor compounds including hydrogen sulfide, an alkyl mercaptan or an alkyl thiol and mixtures thereof by contacting the plant stream with an oxidizing agent that reduces the odor but forms elemental sulfur. The elemental sulfur, and other inorganic, scales that form, or deposit, can be suppressed or removed using a specific aromatic substituted nonionic surfactant material. The use of such a process produces a significant improvement in odor quality while maintaining a clean process facility and low operating pressure drop.

  • Patent number: 6737389
    Abstract: A next textile treatment where the present method can be used to remove contaminants from the textile concerns rewashing. As already observed above, after dyeing textile with reactive dyestuffs, a considerable amount of dyestuff, particularly hydrolyzed dyestuff, is left behind on the textile. Because the hydrolyzed dyestuff is not fast to washing, it should be removed to provide a textile with sufficient washing fastness. In a rewashing treatment of textile dyed with reactive dyestuff, the textile is first rinsed with water to remove alkali and salt. Thereupon, it is rewashed, with the fructan polycarboxylic acid being metered in the form of a 25-40% solution in an amount of 1-3 g/l of water. Rewashing preferably takes place at a temperature of 95-100° C. for a period of 10-30 minutes. After rewashing, the textile is again rinsed with water to remove residues of the hydrolyzed reactive dyestuff.

  • Patent number: 6479454
    Abstract: A peroxygen antimicrobial composition is provided comprising an amine oxide and peroxygen compound. The combination of the two components produces an effective antimicrobial composition, providing a more potent biocide than can be obtained by using these compounds separately. Other components can be added to the composition such as peracetic acid, acetic acid, hydrotrope coupling agents, etc. The composition can be used to sanitize various surfaces such as hard surfaces found in food processing, food service and health care industries as well as to sanitize the surfaces of food and in the treatment of water.
