  • Patent number: 6730621
    Abstract: A disposable substantially damp cleansing article is disclosed having a cleansing composition impregnated onto a flexible substrate such as a non-woven cloth. The impregnated compositions include lathering surfactants and water, the compositions having a viscosity ranging from about 50 to about 300,000 centipoise. Amounts of water range from greater than 15% to no higher than about 40% by weight of the total article.

  • Patent number: 6696068
    Abstract: A cosmetic cream cleansing composition is provided based on the presence of a silicate, a crosslinked carboxyvinyl polymer, a silicone copolyol sulfosuccinate and a carrier. The composition has a viscosity from about 20,000 to about 500,000 centipoise. The combination of components achieves a product of good viscosity, pleasant skinfeel, rich lather and phase stability.

  • Patent number: 6660282
    Abstract: A foaming cosmetic product is provided packaged in a non-aerosol mechanical dispenser. The dispenser includes a container for holding a liquid composition, a dispensing head with a housing enclosing a pump mechanism and a screen material in the flow path to convert liquid composition into a foam, and a diptube for delivering liquid from the container to the dispensing head. The cosmetic composition is an opaque creamy, relatively non-viscous fluid, the creamy appearance imparted by a latex with suspended polymer particles compatible with the foaming mechanism.

  • Publication number: 20030206940
    Abstract: A disposable, single-use, personal care article is disclosed having an active zone, an adjacent non-active zone, and interface therebetween; a benefit agent releasably associated with the active zone; a carrier solvent and optionally a visual indicator associated with the active zone. In one embodiment, the benefit agent, the carrier solvent, and a dye indicator are combined and applied as stripes on the article. The stripes will not substantially bleed into the adjacent non-active zone and will disappear during use of the article indicating that the benefit agent has been transferred to the skin or hair of the user.

  • 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.

  • Patent number: 6551603
    Abstract: A cosmetic sea salt scrub is provided which includes sodium sesquicarbonate and an oil. Sodium sesquicarbonate ordinarily is the major salt present and amounts of this salt relative to the oil may range from about 20:1 to about 5:1 by weight. Mineral oil is particularly preferred as the oil phase. Salt scrubs according to this invention are relatively uniform in composition, easily dispensed from a jar and spread uniformly on the skin.

  • Publication number: 20030064042
    Abstract: An article for cleansing body surfaces is provided which includes an effervescent cleansing composition capable of generating a foam upon contact with water and a pouch for housing the composition. The pouch features first and second substrates, the latter constructed of a non-woven sheet selected from meltblown, spunbond and sheet combinations thereof. Advantageously, a high loft sheet may be bonded to the non-woven sheet. Escape of effervescent gas is controlled by the second substrate thereby maintaining a billowed pouch profile.
