  • Patent number: 6773811
    Abstract: A water-dispersible particle wherein the material comprises (i) one or more polymeric deposition materials having an average repeat unit (I):  wherein at least one or more R groups of the polymer are independently selected from H, a hydrolysable group or a linker group in which when R is a hydrolysable group the degree of substitution is 0 to 3 and when R is a linker group the degree of substitution is 0.01 to 3; (ii) a benefit agent attached to the deposition enhancing part;  characterised in that the water-dispersible particle has a particle size from 20 to 5,000 nm.

  • Patent number: 6756353
    Abstract: Detergent compositions or components are formulated with certain hydrophobically modified cellulosic materials, which provide protection of fabrics, whereof at least 80% or even at least 90% have a particle size of below 1000 microns or even below 850 or even 710 microns. Selection of materials of this particle size results in improved dispersability of the cellulosic material and imparts improved appearance and integrity benefits to fabrics and textiles laundered in washing solutions from such compositions.

  • Patent number: 6734299
    Abstract: A water-soluble or water-dispersible material for deposition onto a substrate during a treatment process, the material comprising: (i) a deposition enhancing part having a polymeric backbone; and (ii) a benefit agent attached to the deposition enhancing part by a hydrolytically stable bond; The material undergoes during the treatment process, a chemical change which does not involve the hydrolytically stable bond and by which change the affinity of the material onto the substrate is increased.

  • Patent number: RE39139
    Abstract: A process for making a detergent tablet by forming a disintegrating agent by compacting cellulose or a cellulose derivative, forming disintegrating agent particles comprising the disintegrating agent, dry mixing a washing- or cleaning-active substance and an amount of the disintegrating agent particles effective to rapidly dissolve or disperse the composition in water, and shaping the resulting mixture into a tablet. The disintegrating agent particles have a particle size distribution of less than 10% by weight smaller than about 0.2 mm particle size and no more than 1% by weight of dust-fine particles.
