  • Patent number: 6168798
    Abstract: The invention provides methods and compositions which are mild and nonirritating for reducing and eliminating skin disorders, particularly blemishes and redness associated with acne. The hydroalcoholic compositions of the invention contain a keratolytic compound, preferably a &bgr;-hydroxy carboxylic acid, more preferably salicylic acid or pharmaceutically acceptable salt thereof; and a glycerophosphate ester or salt, formulated with pharmaceutically acceptable carriers. Preferred glycerophosphate salts for use in the methods and compositions of the invention are sodium glycerophosphate and calcium glycerophosphate. Additional anti-irritancy agents are not required in the compositions of the present invention, as the glycerophosphate salt component uniquely endows the compositions with nonirritant properties. Other components which may be formulated into the compositions of the invention include fragrances, colorants, emollients, humectants and antimicrobial agents.

  • Patent number: 6156076
    Abstract: The present invention describes a two-part oxidative hair dye composition which comprises in one or both component parts at least one polyether polyurethane in combination with at least one cationic conditioning agent. The two component parts of the composition comprise a dye component composition, which includes primary intermediates and couplers, and a developing component composition, which includes an oxidizing agent, such as hydrogen peroxide. It has surprisingly been found by the present inventors that nonionic polyether polyurethane polymers and cationic conditioning agents contained in the oxidative hair dye compositions of the present invention impart and significantly enhance additional conditioning and rheological benefits to the hair. Other components commonly used in oxidative hair dye products can be added to one or both component parts of the compositions of the present invention.

  • Patent number: 6106917
    Abstract: A hair dye product is packaged in a container having a web-printed label. The label is printed on high quality paper or plastic film and has a picture of a human model whose hair is the color sought to be obtained by the hair dye. The printing process provides an accurate reproduction of the tone and hue of each hair color over the entire production run of the labels. The container may be a relatively low cost generic container of web-printed paperboard or plastic produced in a high volume production run.

  • Patent number: 6019988
    Abstract: The invention provides methods and means for enhancing the epidermal, transdermal and dermal permeation of a topically applied pharmacologically active agent (e.g., a drug or medicament) which has a low rate of skin penetration in the absence of a permeation enhancer and which is unstable and degrades during long-term storage with particular permeation enhancers. Also provided by the invention are methods and means to increase the skin penetration of a pharmacologically active agent which has a normally low rate of skin permeation and causes the instability and degradation of a permeation enhancer with which it is combined over a long period of time. Provided by the invention are at least one first composition containing a drug, a pharmaceutically acceptable salt, chemical derivative or formulation thereof, in a dermatologically acceptable vehicle, and at least one second composition containing a permeation enhancer in an acceptable vehicle.

  • Patent number: 6010690
    Abstract: The invention provides compositions for relaxing and conditioning keratinous fibers, particularly human hair. The compositions of the present invention have a high pH, i.e., a pH greater than 10, preferably, in the range of about 11 to about 14, more preferably about 12 to about 13.5, and include as a conditioning additive a cationic guar. Surprisingly, the cationic guar maintains stability, viscosity and activity over time in the highly alkaline pH of the inventive hair relaxer and conditioning compositions of the present invention. The relaxer compositions of the present invention afford beneficial effects to the user, such as softness and ease of wet combing, and cause less damage to hair following application and use. In addition, the conditioning relaxer compositions of the present invention remain on the hair and provide lasting conditioning and relaxing effects after one or more shampoos.

  • Patent number: 5964149
    Abstract: A method of printing multi-color images on pressure sensitive labels carried on a web uses a disk shaped mark for each color which is printed to form the image. The disks (spots) are printed on the image, or elsewhere on the top layer of the web, with one disk being printed on top of the other, so that the marks coincide in size, shape and position. If a color is misregistered, it appears as a crescent which extends beyond the multi-colored disk. Such misregistration may be immediately viewed on a video magnifier, using at least 400.times. magnification, and the misregistration corrected.
