  • Patent number: 6379399
    Abstract: Oxidative hair dyeing systems are provided that are “root seeking”, i.e., which produce more intense initial coloration on new growth, less porous hair compared to the initial coloration produced in older, damaged, more porous hair. More equalized coloration along the shaft of hair can be obtained with the “root seeking” dyeing products.

  • Patent number: 6348439
    Abstract: The invention provides compositions for providing body, fullness and texture to otherwise fine or very fine keratinous fibers, particularly human hair. The compositions of the present invention have a high pH, e.g., about 8 to about 10 when the compositions contain cationic polymer, and a pH of about 8 to about 14, preferably about 8.5 to about 13, and more preferably, about 8.5 to about 10 when the compositions contain no cationic polymer. The compositions include one or more nonionic and/or cationic polymers, which, in combination with the high pH of the composition, lift the hair cuticle and allow the deposition of polymer, thus resulting in increased fullness and texture to the hair. The compositions of the present invention may be in the form of known hair care products such as, for example, shampoos, rinses and conditioners. In addition, the compositions can be formulated, for example, as lotions or creams, and the like, for consumer use.

  • Patent number: 6256809
    Abstract: There is disclosed a waste prevention system which avoids the discharge, inadvertent or otherwise, of laboratory waste, into a public sewage system and subsequently into the natural environment. The system employs, in combination, a laboratory sink having cooperatively connect thereto a carboy for collecting pollutants. The carboy is provided with elements to permit removal of samples of materials delivered thereto from the sink for testing of the same to determine the presence of pollutants. In the event no pollutants are present, the carboy may simply be opened and any wash or rinse water from the sink can be delivered into a public sewage system and then to the environment.
