  • 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.

  • Patent number: 11886760
    Abstract: A print driver store is usable for redirection printing in a virtualized computing environment that supports virtual desktops. Native print drivers are uploaded to the print driver store from a client side. When an agent attempts to instantiate a virtual printer at the agent side that corresponds to a physical printer at the client side, the agent checks to determine if a native print driver for the physical printer is installed at the agent side. If the native print driver is not installed, then the agent obtains the native print driver from the print driver store and installs the native print driver at the agent side. The agent completes the instantiation of the virtual printer at the agent side and associates the native print driver with the virtual printer.
