  • Publication number: 20240174950
    Abstract: A novel alkoxylated polyamines obtainable by a process including the steps a) to d) and having amphiphilic properties. According to step a), a polyamine containing up to 10 amine-groups as such is reacted with a first alkylene oxide (AO1) in order to obtain a first intermediate (I1). Said first intermediate (I1) is reacted with a lactone and/or a hydroxy carbon acid in step b) in order to obtain a second intermediate (I2) followed by step c), wherein said second intermediate (I2) is reacted optionally with alkylene oxide in order to obtain a third intermediate (I3). Afterwards, said third intermediate (I3) is reacted in optional step d) with a second alkylene oxide (AO2) in order to obtain the novel alkoxylated polyamines. The alkoxylated polyamines may also be included in cleaning compositions and/or in fabric and home care products, and the compositions or products as such.

  • Publication number: 20240110009
    Abstract: Disclosed herein is a method for preparing a multilayer coating system on a substrate including at least the steps of applying a first coating material composition to a substrate (step (1)), applying a second coating material composition to the first coating film formed in step (1) prior to curing the first coating film and forming a second coating film (step (2)) and jointly curing the first and second coating films (step (3)). Also disclosed herein are a multilayer coating system on a substrate, which is obtainable by the method and a method of using an amino resin (AR) as a migrating crosslinking agent.

  • Publication number: 20160348032
    Abstract: The present invention relates to the use of ortho-substituted ethoxylated Al or Zn-phthalocyanine compounds as photobleach agents for the removal of stains and soil on textile materials, particularly in laundry detergents. A further aspect of the invention is a process for removing stains and soil from textile materials using the Al or Zn-phthalocyanine compounds in a washing process and exposing the washed textile material to actinic radiation. Still further aspects are detergent and granule formulations containing ortho-substituted ethoxylated Al or Zn-phthalocyanine compounds and also new orthosubstituted ethoxylated Zn-phthalocyanine compounds as such.
