20130095047 | COSMETIC COMPOSITION - A cosmetic composition including: (i) at least one amphiphilic copolymer; and (ii) one or more cosmetically acceptable diluents, excipients or carriers; wherein the amphiphilic copolymer is selected from the group consisting of a graft copolymer including a hydrophobic straight or branched chain carbon-carbon backbone having at least one hydrophilic side chain attached thereto; a graft copolymer comprising a hydrophilic straight or branched chain backbone having at least one hydrophobic side chain attached thereto; a block copolymer including at least one hydrophilic block and at least one hydrophobic block in a straight or branched chain backbone; and a cross-linked/network copolymer. | 04-18-2013 |
20120302487 | COMPOSITE - A composite includes: one or more core units comprising a bleach activating agent; and an alkali soluble polymer coating on the surface of said one or more core units. | 11-29-2012 |
20100266513 | AMPHIPHILIC POLYMERIC MATERIAL - The present invention concerns an amphiphilic polymeric material which comprises a straight or branched chain carbon-carbon backbone and a multiplicity of side chains attached to the backbone, wherein the side chains have formula (I). At least one of R | 10-21-2010 |
20100233314 | SOLVENT-FREE SYNTHESIS OF AMPHIPHILIC POLYMERIC MATERIAL - The present invention provides a method for making a composition comprising an amphiphilic polymeric material which comprises a straight or branched chain carbon-carbon backbone and a multiplicity of side chains attached to the backbone; wherein in the method, backbone precursors comprising acylating groups are mixed with side chain precursors which comprise a nucleophilic group at at least one terminus, to form a reaction mixture; the backbone precursors, side chain precursors and/or the reaction mixture are heated; the reaction mixture is stirred; and the nucleophilic groups react with the acylating groups to form the amphilphilic polymeric material wherein the side chains are linked to the backbone via acyl linkages; characterised in that the reaction mixture does not comprise organic solvent. | 09-16-2010 |
20100233100 | AMPHIPHILIC COPOLYMERIC MATERIAL - An amphiphilic polymeric material which has a straight or branched chain polymer backbone and a multiplicity of side chains attached to the backbone, wherein the backbone is a copolymer of at least one ethylenically-unsaturated aliphatic hydrocarbon monomer and maleic anhydride, or is a terpolymer of maleic anhydride, ethylene, and a further ethylenically unsaturated monomer. A method of synthesising said polymeric material is also provided, together with chewing gum bases, compositions and emulsions comprising amphiphilic polymeric materials. | 09-16-2010 |
20100215799 | CHEWING GUM COMPOSITION - Chewing gum base including i. 1 to 99% by weight of a polymeric material which has a straight or branched chain carbon-carbon backbone and a multiplicity of side chains, and is substantially insoluble in water; ii. from 0-6% by weight wax; iii. up to 99% by weight of an elastomeric material different to the polymeric material; and iv. 0 to 20% by weight of an elastomer plasticiser; in which the total amount of polymeric material and elastomeric material is at least 10% by weight of the chewing gum base. A chewing gum composition including this chewing gum base, and methods of manufacture, are also provided. | 08-26-2010 |
20100209359 | MEDICATED CHEWING GUM - The present invention provides a chewing gum composition comprising a chewing gum base, a biologically active ingredient, a polymeric material and one or more sweetening and flavouring agents, wherein the polymeric material is amphiphilic, has a straight or branched chain carbon-carbon backbone and a multiplicity of side chains attached to the backbone. A method of making the chewing gum composition is also provided. | 08-19-2010 |
