  • Patent number: 5043091
    Abstract: Detergent laundry bars of improved foaming, better skin feel/mildness and fabric softening properties are provided. These laundry bars are based on alkyl polysaccharide nonionic surfactants with alkyl benzene sulfonate anionic surfactant, detergent builder and filler. Processing into laundry bars which additionally contains high melting higher fatty alcohol sulfate anionic cosurfactant is greatly facilitated by pre-blending the alkyl polysaccharide nonionic surfactant and higher fatty alcohol sulfate cosurfactant prior to feeding the mixture to the mixer and plodder.
