  • Patent number: 7262160
    Abstract: Enhanced UV blocking is provided to clothing by washing the clothing in a composition including a UV blocking dye and at least one additional water-soluble material which serves as a matrix and/or a dispersant for the dye in the washing machine. The dye is initially in the form of a solid tablet or pellet preferably also containing a disintegrant, or inside a water-soluble envelope. When placed in the washing machine with the clothing and the washing water, the pellet or tablet disintegrates and dissolves releasing the UV protectant dye to the clothing.

  • Patent number: RE39139
    Abstract: A process for making a detergent tablet by forming a disintegrating agent by compacting cellulose or a cellulose derivative, forming disintegrating agent particles comprising the disintegrating agent, dry mixing a washing- or cleaning-active substance and an amount of the disintegrating agent particles effective to rapidly dissolve or disperse the composition in water, and shaping the resulting mixture into a tablet. The disintegrating agent particles have a particle size distribution of less than 10% by weight smaller than about 0.2 mm particle size and no more than 1% by weight of dust-fine particles.
