  • Patent number: 11896695
    Abstract: According to the present invention there is provided composition in the form of an oil-in-water emulsion having a viscosity of between 15,000 cP (15 Pa-s) and 45,000 cP (45 Pa-s) at 23° C., having a pH of between 2 and 6 and comprising: (i) at least 1.6 wt. % of at least one cross-linked anionic polyelectrolyte resulting from the polymerisation of partially or completely salified 2-methyl 2-[(1-oxo 2-propenyl)amino]1-propane sulfonic acid, with at least one neutral monomer chosen from the N,N-dialkyl acrylamides, wherein each of the alkyl groups comprises between one and four carbon atoms, and at least one monomer of formula (B): wherein R represents a linear or branched alkyl radical comprising eight to twenty carbon atoms and n represents a number greater than or equal to one and less than or equal to twenty, in the presence of at least one cross-linking agent; (ii) at least 4 wt. % of at least one polysorbate; (iii) at least 0.1 wt. % of at least one polysaccharide gum; and (iv) between 6 wt. % and 30 wt.

  • Patent number: 11484486
    Abstract: According to the present invention there is provided a cosmetic composition comprising a cosmetically acceptable carrier and a surfactant system consisting of: (i) an anionic surfactant; (ii) an amphoteric surfactant; and (iii) a non-ionic surfactant, wherein the anionic surfactant is present in an amount of from about 0.5% to about 25% by weight of the surfactant system, wherein the amphoteric surfactant is present in an amount of from about 0.5% to about 50% by weight of the surfactant system, wherein the non-ionic surfactant is present in an amount of from about 0.5% to about 45% (e.g. 43%) by weight of the surfactant system, and wherein the total amount of the surfactant system present in the cosmetic composition is from about 1.5% to about 25% by weight of the composition.
