  • Patent number: 10688025
    Abstract: The invention provides a personal cleansing composition comprising, in an aqueous continuous phase: (i) from 5 to 30% by weight of one or more anionic cleansing surfactants; (ii) from 0.1 to 10% by weight of discrete, dispersed droplets of emulsified silicone with a mean diameter (D3,2) of 4 micrometres or less; (iii) from 0.1 to 5% by weight of microcapsules in which a core comprising benefit agent is encapsulated in a polymeric shell, and (iv) from 0.1 to 0.5% by weight of a combination of cationic polymers comprising: (a) at least one cationic polygalactomannan derivative having a mean charge density at pH 7 from 0.2 to 2 meq per gram; and (b) at least one acrylamidopropyltrimonium chloride/acrylamide copolymer having a mean charge density at pH 7 from 1 to 3 meq per gram.

  • Patent number: 7781386
    Abstract: The invention provides an aqueous shampoo composition comprising: (i) one or more anionic cleansing surfactants; (ii) preferably, discrete, dispersed droplets of a water-insoluble conditioning agent with a mean droplet diameter (D3,2) of 4 micrometers or less; (iii) one or more cationic polymers (A) selected from cationically modified acrylamide polymers having a cationic charge density at pH7 of less than 1.0 meq per gram, cationically modified celluloses and mixtures thereof, and (iv) one or more cationic polymers (B) selected from cationically modified acrylamide polymers having a cationic charge density at pH7 of greater than 1.0 meq per gram, cationically modified polygalactomannans, and mixtures thereof, wherein the composition comprises a cationic polymer other than a cationically modified acrylamide polymer.
