  • Detergent composition
    Patent number: 8841245
    Abstract: An automatic dishwashing detergent composition comprising: a) an alkoxylated polyalkyleneimine said alkoxylated polyalkyleneimine comprising a polyalkyleneimine backbone, alkoxy chains and quaternization groups wherein the alkoxylated polyalkyleneimine has a degree of quaternization of at least 5% and wherein: i) the polyalkyleneimine backbone represents from 0.5% to 40% by weight of the alkoxylated polyalkyleneimine; ii) the alkoxy chains represent from 60% to 99% by weight of the alkoxylated polyalkyleneimine; and b) a bleach system comprising bleach and optionally a bleach enhancer.
