  • Publication number: 20120091368
    Abstract: A method and kit for producing reversibly dyed soft contact lenses. The contact lenses are submerged in saline solution and a dye is added to the saline solution, either directly or by means of a strip that has been impregnated with the dye. Preferred dyes include the common dyes sodium fluorescein, lissamine green, and rose bengal. After a period of time, the lens absorbs the dye and can be removed from the solution and placed on the eye. Once the lens is illuminated with ultraviolet light, it will glow or fluoresce. This creates a dramatic effect, particularly in dimly lit areas. The dyeing method does not utilize heat and thus is reversible. Soaking the lens in additional saline solution for a period of time will cause the dye to return to its non-dyed state.

    Abstract: A dye formulation is disclosed that includes a vegetable oil ester based solvents that have carbon chain lengths of C-1 to C-18, a solvent dye that is a true liquid dye dissolved in the vegetable oil ester for imparting color to the dye formulation, and reduced sulfur levels in commercially available dye formulations as compared to those in hydrocarbon based solvent systems. Sulfur content is typically reduced to 2-3 percent of dye formulations in hydrocarbon based solvents. The formulations are particularly useful for tagging petroleum substrates as well as writing instrument and ink jet formulations.

  • Publication number: 20090089941
    Abstract: The present invention relates to new methods of producing polymer composite materials. More specifically, the invention involves a process in which layered materials including clays and other inorganic materials are dispersed into polymer systems to create polymer nanocomposite films. The resulting films exhibit improved resistance to fading when compared to polymer films that lack the additional layered materials.

  • Publication number: 20090089942
    Abstract: A method of tinting a plastic article is provided. The method comprises the steps of (a) providing a plastic article comprising a thermoset or thermoplastic polymer; (b) contacting at least a portion of the surface of said plastic article with a treatment composition comprising at least one dye and water; (c) maintaining said portion of said plastic article in contact with said treatment composition for a period of time at least sufficient to form a tinted plastic article; (d) removing said tinted plastic article from contact with said treatment composition; and (e) rinsing said tinted plastic article with water to remove excess dye. The method is carried out in the absence of an organic solvent, without the need for fixing or further processing steps.

  • Patent number: 7494515
    Abstract: The present invention relates to the field of hair care. More specifically, the present invention relates to the conditioning of hair after it has been oxidized in a coloring, bleaching or perming treatment. Superior conditioning is obtained by providing a cationic polymer to the hair while it is subjected to the oxidizing treatment, and then the oxidized hair is subjected to a conditioning treatment with a composition comprising a functionalized silicone.

  • Publication number: 20080282483
    Abstract: Solute-loaded polymer microparticles are obtained by immersing microparticles in a bath comprising a selected solute dissolved in a ternary solvent system. A first solvent of the ternary system is a strong solvent for both the solute and the polymer from which the microparticle was formed. A second solvent is a weak solvent or non-solvent for the solute and the polymer (tuning solvent). A third solvent is a weak solvent or non-solvent for the solute and polymer, but serves as a co-solvent with respect to the first and second solvents in that it is miscible with both the first and second solvents. The amount of solute incorporated into the microparticles is controlled by adjusting the ratio of solute with respect to the microparticle polymer, and by adjusting the composition of the ternary solvent system, principally the amount of tuning solvent.

  • Publication number: 20080256725
    Abstract: A method of applying a consumable, in particular a wear indicator dye, to toothbrush filaments and/or other wearing parts for personal needs, in which the consumable is added to a medium which is subjected to pressure above atmospheric, and the toothbrush filaments and/or the wearing part are exposed to the pressurized mixture of consumable and medium for a predetermined exposure period. The medium to which the consumable is added includes CO2 as an essential constituent. The mixture of consumable and CO2 can be circulated in a pressure vessel under high pressure, so that the mixture is caused to flow around the toothbrush filaments or the corresponding wearing part.
