  • Patent number: 10808075
    Abstract: Provided herein are polymers obtainable by a process including the steps a) and b) described below. In Step a) at least one component a1) is condensed to obtain a polyether having remaining hydroxyl groups. Component a1) is at least one component selected from N-(hydroxyalkyl) amins according to formula (Ia) and/or (Ib) as defined below. Besides component a1), further components can be present in the condensation step a). In step b) a part of the remaining hydroxyl groups are reacted with at least one alkylene oxide. The alkoxylation according to step b) is carried out in a substoichiometric way. The ratio of i) the alkylene oxide versus ii) the sum of the amount of the remaining hydroxyl groups is >0:1 to <1:1 [mol/mol]. Further provided herein is a process for preparing such polymers and derivatives of the polymers by quaternization, protonation, sulphation and/or phosphation.

  • Publication number: 20050009720
    Abstract: The invention is directed to aqueous liquid laundry detergent compositions for cleaning and imparting fabric care benefits to fabrics laundered therewith. Such compositions comprise (A) at least one detersive surfactant; (B) droplets of a silicone blend comprising a nitrogen-containing amino or ammonium functionalized polysiloxane and a nitrogen-free non-functionalized polysiloxane; and (C) at least one additional non-silicone laundry adjunct selected from detersive enzymes, dye transfer inhibiting agents, optical brighteners, suds suppressors and combinations thereof. The functionalized polysiloxane component of the silicone blend has a relatively low, i.e., less than 30 mol %, content of reactive/curable groups, a nitrogen content which ranges from 0.05% to 0.50% by weight and a viscosity which ranges from 0.00002 m2/s to 0.2 m2/s. The nitrogen-free, non-functionalized polysiloxane material ranges in viscosity from 0.01 m2/sec to 2.0 m2/sec.
