  • Fitment and bottle
    Patent number: 7097076
    Abstract: A container including a fitment having an outer wall and a pour spout. The fitment outer wall includes a first product exit aperture. A bottle finish includes one or more locking surfaces abutting the outer wall of the fitment, and the finish locking surface includes a channel which directs product trapped between the outer wall of the fitment and the inner wall of the finish to the first product exit aperture and then to the exterior of the container or directly to the exterior of the container. This permits egress of residual drops of product from the container. Alternatively, the channel can extend to the top of the finish.

  • Efficient two-step method of coloring and lightening hair with less damage
    Patent number: 7066968
    Abstract: The present invention relates to a 2-step methods, and compositions for providing more vibrant, natural and long-lasting color to hair and at the same time reducing hair fiber damage associated with alternative current methods. In the first step the hair is contacted for a period of time with a dye precursor mixture containing specific oxidative hair dye precursors under conditions where these dyes are substantially inactive. Color is then developed in a second step by contacting the hair with a mixture of a peroxide compound and a persulfate salt. Surprisingly the 2-step method leads to considerable “lift” or lightening without negatively impacting the coloring ability of the oxidative dye. The invention also relates to kits providing the means to accomplish these steps.
