  • Patent number: 5773396
    Abstract: A composition for cleaning and wetting contact lenses comprising a non-amine polyethylenoxide-containing copolymeric material having a hydrophilic-lipophile balance (HLB) of at least about 18, a surface active agent having cleaning activity for contact lens deposits and having HLB values of less than 18, and a wetting agent. Preferred embodiments of the present invention include those having from about 0.001 to about 10 weight percent of a non-amine polyethyleneoxy-containing materials, particularly those selected from: ethoxylated glucose derivatives, ethoxylated ethers of sorbitol, copolymers comprising ethyleneoxy and propyleneoxy monomeric units, and mixtures thereof. Preferred embodiments further include from about 0.001 to about 5 weight percent of the surface active agent and from about 0.1 to about 10 weight percent of a wetting agent selected from: cellulosic materials, silicone polymers containing an alkyleneoxide side chain, polyvinyl alcohols, polyvinyl pyrrolidones, and mixtures thereof.

  • Patent number: 5604189
    Abstract: A composition for cleaning and wetting contact lenses comprises a polyethyleneoxide-containing material having a hydrophile-lipophile balance (HLB) of at least about 18, a surface active agent having cleaning activity for contact lens deposits, and a wetting agent.
    Type: Grant

    Date of Patent: February 18, 1997
    Inventors: Hong J. Zhang, Edward J. Ellis, Stanley J. Wrobel, Chimpiramma Potini
  • Patent number: 5500144
    Abstract: Compositions for the care of contact lenses include a silicone polymer containing an alkyleneoxide side chain.
    Type: Grant
    Filed: April 12, 1995

  • Patent number: 5496540
    Abstract: An oral composition, such as a paste or gel dentifrice or a liquid mouthwash, containing a substantially water insoluble non-cationic antibacterial agent, such as triclosan, which, when used to clean the teeth or rinse the mouth, acts to decrease plaque on the teeth, is packaged in a dispensing container which includes a solid polymeric material, such as polyfluoroethylene, which is compatible with the antibacterial agent so that excessive loss of anti-plaque activity of such agent on storage is avoided. Alternatively, various other polymers may be employed as container parts, which normally would cause excessive losses of anti-plaque action of the antibacterial agent in the composition, but such action is countered by the presence of a stabilizer, such as a terpene, e.g., limonene, in the oral composition formula.
    Type: Grant
