  • Patent number: 7943058
    Abstract: Tagged scale-inhibiting polymers, compositions comprised thereof and preventing or controlling scale formation therewith, the tagging units being units deriving from a monomer having the formula X2C?CYY? wherein X is a hydrogen atom, or a C1-C4 alkyl radical, Y is a hydrogen atom or a C1-C4 alkyl radical, Y? is a radical having formula -L-Arom, wherein L is a covalent bond or a divalent organic linking group optionally comprising heteroatoms, and Arom is a group comprising at least two conjugated aromatic rings, said rings comprising conjugated carbon atoms, and, linked to said carbon atoms, hydrogen atoms or other substituents.
    Type: Grant

    Date of Patent: May 17, 2011
    Assignee: Rhodia Chimie
    Inventors: Emma Hills, Pascal Chapon
  • Patent number: 7820752
    Abstract: The invention concerns the use as thickening agent of an aqueous composition comprising at least 5 wt. % of one or several phase-organized surfactant(s) comprising giant micelles whereof the average length represents at least four times the mean diameter, of at least a charged statistic amphiphilic polymer soluble in the aqueous composition, said amphiphilic polymer being used in a content such that the viscosity of the aqueous composition comprising the amphiphilic polymer is at least three times higher than that of the composition without amphiphilic polymer and than that of an aqueous composition comprising only the amphiphilic polymer. The invention also concerns aqueous compositions comprising said amphiphilic polymer, and are particularly designed for cosmetic uses.

  • Patent number: 6358279
    Abstract: A mini capsulorhexis valve device is composed of a curved, flexible discoid flap-valve member shaped to align with an ocular lens capsular bag inner surface, and a curved, flexible retainer member shaped to align with an ocular lens capsular bag outer surface, the curved, flexible retainer member being attached at a fastening point to the curved, flexible discoid flap-valve member. Attachment of the curved, flexible discoid flap-valve member to the curved, flexible retainer member may be via bonding with a silastic adhesive. In a method of accessing an ocular lens, the mini capsulorhexis valve device establishes a portal controlling access to an ocular lens. The method may include inserting a cannula through the mini capsulorhexis valve device to permit removal of a crystalline lens matrix and replacement thereof with a capsular filling material.
