  • Patent number: 7897556
    Abstract: The invention relates to encapsulated bleaching agent particles. Said particles consist of a core that contains a bleaching-agent active ingredient and a coating of water-soluble material that at least partially surrounds said core, the core containing peroxocarboxylic acid and the coating material containing polyvinyl alcohol. The particles can be produced by introducing a particulate peroxocarboxylic acid into a fluidized bed, by spraying an aqueous solution containing polyvinyl alcohol onto said bed and by subsequent drying or spray drying.

  • Publication number: 20040067863
    Abstract: The invention set out to improve the oxidizing and bleaching effect of inorganic peroxygen compounds in dishwashing, more particularly machine dishwashing, in terms of their storage stability. This was essentially achieved by using particulate compounds corresponding to formula R1R2R3N+CH2CN X−, in which R1, R2, and R3 independently of one another represent an alkyl, alkenyl or aryl group containing 1 to 18 carbon atoms, in addition to which the groups R2 and R3 may even be part of a heterocycle including the N atom and optionally other hetero atoms, and X is a charge-equalizing anion. Dishwashing detergents, more particularly machine dishwashing detergents, contain about 1% by weight to 10% by weight of this bleach-boosting agent.

  • Patent number: 6420323
    Abstract: A low-foam emulsifier system is presented containing (a) an ethoxylate/propoxylate of one or more C8-C18 fatty alcohols, where the ethoxylate/propoxylate contains 2 to 6 ethylene oxide units and 4 to 8 propylene oxide units, with (b) a fatty alcohol propoxylate or distillation residue of fatty alcohol or fatty alcohol propoxylate, where the fatty alcohol contains 12 to 24 carbon atoms and up to three propylene oxide units. The weight ratio of (a) to (b) is from 1:0.3 to 0.3:1. The emulsifier system produces a low amount of foam, and is useful in industrial metal processing applications such as cleaning, corrosion protection or cooling lubricant emulsions.
