Abstract: 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 synthesizing said polymeric material is also provided, together with chewing gum bases, compositions and emulsions comprising amphiphilic polymeric materials.

Abstract: A amphiphilic polymeric material that includes 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 R1 and R2 is the group —C(O)Q; wherein Q includes a hydrophilic polymeric group terminated with an amine.

Abstract: 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.

Abstract: 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).
