  • Patent number: 7524802
    Abstract: The invention relates to a composition suitable for use as in a vehicle wash which composition includes a micro-organism to digest organic matter washed from the vehicle. By including a microorganism in wash water used in a vehicle wash, there are various advantages including the fact that dosing of the vehicle wash by the micro-organism is proportional to the use of the vehicle wash. Thus the more the vehicle wash is used, generally the more organic matter will accumulate but as dosing is proportional to use, more micro-organism is supplied to combat the increased level of organic matter. As a result the growth rate of organic matter is greatly reduced allowing wash water to be recycled for longer resulting in reduced operating costs for the vehicle wash, especially as there is less or no need to apply a biocide to control foul odour.

  • Patent number: 7396417
    Abstract: A degreasing method for descaling or removing laser scales from iron-containing metal part surface by treating the iron-containing metal part surfaces that is optionally tainted with laser scales with an aqueous solution containing at least one type of highly water-soluble and complexed with Fe ions carboxylic acid, at least one type of salt of at least one type of carboxylic acid exhibiting the same action and at least one type of fatty amine ethoxylate, wherein the solution is buffered, the Fe ions are carried into the solution and at least partially complexed, increasing the pH value of the solution for descaling with respect to at least one type of carboxylic acid. The entire concentration of carboxylic acids and the salts thereof is increased for descaling by 2 to 20% by weight.

  • Patent number: 7390776
    Abstract: A liquid detergent builder which is highly compatible with a surfactant and gives transparent liquid detergents having extremely excellent detergency, a liquid detergent containing the builder, and a liquid detergent containing an acrylic acid-based polymer (salt) having excellent clay dispersibility and good compatibility with a surfactant. The liquid detergent builder comprises an acrylic acid/maleic acid-based copolymer (salt), wherein the acrylic acid/maleic acid-based copolymer (salt) contains maleic acid (salt) in an amount of 5-90 mol % per mole of the sum of acrylic acid (salt) and maleic acid (salt), and a product (MA×Mw) of a weight average molecular weight (Mw) of the copolymer (salt) and a proportion (MA (mol %)) of the maleic acid (salt) in the copolymer (salt) is 450,000 or less.

  • Patent number: 7387130
    Abstract: A composition for removing resists and etching residue from substrates containing at least one nucleophilic amine compound having oxidation and reduction potentials, at least one organic solvent, water and, optionally, a chelating agent is described. The chelating agent is preferred to be included since it provides added stability and activity to the cleaning composition so that the composition has long term effectiveness. If a chelating agent is not present, the composition, while providing for adequate stripping and cleaning upon initial use of the composition following mixing, has only short term stability. In this latter instance, the nucleophilic amine compound and organic solvent components of the composition preferably are maintained separate from each other until it is desired to use the composition. Thereafter, the components are combined.

  • Patent number: 7371718
    Abstract: A liquid fabric softener composition is provided which includes a texture enhancing component, such as a long chain difatty acid, that is deposited on a fabric during laundering, the deposited enhancing component changing the “feel” of the fabric. Preferably, the deposited enhancing component substantially detaches from the fabric in subsequent laundering cycles to reduce build-up. The enhancing component is preferably water-insoluble in an acidic pH, such as during the rinse cycle occurring after washing fabrics with a detergent, yet water soluble in an alkaline medium enabling the deposited enhancing component to be detached from fabric in subsequent “wash” cycles.
