  • Patent number: 11879112
    Abstract: The present invention is in the field of fabric cleaning compositions; in particular powder detergent compositions having foaming and cleaning characteristics in the main wash, yet significant foam reduction during rinse. Accordingly the present inventors have investigated ways of improving the defoaming ingredient such that the defoaming ingredient has improving foam-subsiding effects in the rinse stage. However they found that incorporating a monoester of glycerol of unsaturated fatty acids in a cleaning composition has adverse effects on the perfume impact of the cleaning composition. The inventors have found that the disadvantages of the prior art can be overcome, if a monoester of glycerol and unsaturated fatty acid is sorbed by a porous carrier material having a specific pore size and pH ranges. The inventive defoaming ingredient did not masked and/or altered the perfume delivery of the detergent composition.

  • Patent number: 11447720
    Abstract: The present invention provides a liquid detergent composition comprising anionic surfactants, optionally one or more nonionic surfactants, polyethylene glycol, and water, and wherein the liquid detergent composition has a pH of 7.0 to 7.5, wherein the liquid detergent composition has a viscosity at 25° C. and 20 s?1 in the range of 5 to 100 mPa s?1, and wherein the liquid laundry composition has stable viscosity between a temperature range of 10 and 40° C., and wherein the composition is adapted for application with a hand-held dispensing device used for washing by hand. The liquid detergent composition has a low constant viscosity throughout the temperature range of normal use and produces a stable foamy lather.
