  • Publication number: 20030206878
    Abstract: A substantially dry composition, especially for personal care products is provided which includes a colorant activatable in water to release a visual color, and an oil-soluble carrier. The colorant is insoluble in the carrier and the visual color is not imparted to the composition in its substantially dry state. Addition of water to the composition activates a color change which renders the visual color perceivable by a consumer. Color changes can be associated as a signal of performance by a consumer.

  • Patent number: 6610311
    Abstract: A packaged effervescent product is provided which includes a sachet surrounded by an outer package film sealing the sachet against water vapor transmission. The sachet is a cosmetic article which includes an effervescent cleansing composition of an acid material such as citric add and an alkaline material such as sodium bicarbonate. The composition is held within the sealed sachet or pouch. At least one wall of the pouch is water permeable. The outer package film is formed of a material which must have a breathability for carbon dioxide. Any carbon dioxide generated during storage is thereby allowed to slowly diffuse into the atmosphere while still minimizing the amount of water which may enter the package.

  • Patent number: 6610312
    Abstract: A wiping article is provided which includes an effervescent cleanser composition held within a pouch formed from a first and second substrate sheet. At least one of the substrate sheets must be water permeable. The effervescent composition is an intimate mixture of an acid material such as citric acid and an alkaline material such as sodium bicarbonate. Water contact causes the combination to effervesce. A dry surfactant such as sodium cocoyl isethionate in contact with the water and effervescing carbon dioxide results in a highly pleasant sudsing system. Skin benefit agents may be included within the composition. The effervescent action may improve deposition of the skin benefit agents onto the skin.

  • Publication number: 20030150765
    Abstract: A packaged cosmetic product is provided which includes multiple effervescent sachets placed within a tub with an open dispensing mouth. A carbon dioxide breathable and moisture barrier foil is arranged sealingly to close the dispensing mouth. Any carbon dioxide generated during storage, usually as a result of moisture prematurely effervescing powder within the sachets, is allowed to slowly diffuse into the atmosphere through the window formed by the special foil. The tub is formed of walls which do not have any substantial carbon dioxide breathability but do prevent inward moisture penetration.
