  • Publication number: 20020131985
    Abstract: A system is described for providing a customized, personal care product to a consumer at a location, typically the point of sale, that is remote from a second location in which a personal care product base composition is prepared. A selection of performance agents of different classes with a common vehicle is made available to the consumer for custom formulation of a personal care product with the desired attributes. The system typically includes a product base, a fragrance part, and one or more performance agent parts that may contain benefit agents, botanical extracts, active ingredients for skin and hair, and the like. A blank vehicle is substituted if insufficient performance agents are selected.

  • Patent number: 6451331
    Abstract: A wiping article is provided which includes an effervescent cleanser composition held within a sachet, at least one wall of the sachet including at least one pleat. The presence of pleats allows expansion room within the sachet to accommodate effervescent action. It also results in an ergonomically pleasant pillow configuration. Advantageously, the sachet is formed of two sheets with the second sheet being relatively more rigid than the first sheet and non-pleated which permits easier graspability by a user's hand. Additionally, at least one of the sheets should be water permeable. In a preferred embodiment, 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. Skin benefit agents may be included within the composition.

  • Publication number: 20020071859
    Abstract: A cosmetic towelette is provided which includes a water-insoluble substrate and a fluid cosmetic composition impregnated into the substrate. The composition has a viscosity ranging from about 1 cps to 10,000 cps. The composition includes a water phase, a sunscreen phase and a surfactant system. The sunscreen phase is immiscible with the water phase and contains at least 25% organic sunscreen agent. Towelettes impregnated with the composition impart an effective SPF to the skin when applied thereto.

  • Patent number: 6391835
    Abstract: A disposable substantially dry cleansing article is disclosed having a lathering surfactant and a C5-C12 alkyl diol impregnated into a flexible substrate such as a non-woven cloth. The alkyl diol primarily is a process aid which may concurrently improve aesthetics and increase latherability. Hexylene glycol is the preferred diol. Best performance is achieved with an alkyl diol to total lathering surfactant weight ratio from about 1:1 to about 1:8.

  • Publication number: 20020039558
    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: 20020037255
    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: 6306412
    Abstract: An adhesive cosmetic strip is provided which includes a flexible water-insoluble substrate, an adhesive composition deposited onto the substrate and an agent interactive with water present in a sufficient quantity to induce a change of temperature of the strip. When applied to the skin, the strip is warmed by a reaction between water and an exothermic or endothermic agent held within the strip. Moisture within the skin or externally applied water penetrates the strip and will react with the agent to cause an increase or decrease in temperature.

  • Patent number: 6287582
    Abstract: A disposable towelette product is provided which includes a flexible water-insoluble substrate such as a tissue impregnated with an alpha- or beta-hydroxycarboxylic acid in a cosmetically acceptable carrier vehicle. Impregnated cosmetic composition in water will have a pH no higher than 6.8. A silicone microemulsion is present to minimize any stickiness resulting from deposition of the hydroxycarboxylic acid by the towelette onto the skin. In the presence of fatty acid group containing surfactants, the silicone microemulsion controls foul odors that the surfactants may emit through hydrolysis at low pH.

  • Patent number: 6270783
    Abstract: An adhesive cosmetic strip is provided which includes a flexible water-insoluble substrate, an adhesive composition deposited onto the substrate, a liquid crystal thermochromic substance, and an agent interactive with water to ensure a temperature rise of at least 2° C. in the strip. The thermochromic substance may be impregnated into the substrate or dispersed within the adhesive composition. When applied to the skin, the strip is warmed by a reaction between water and an exothermic or endothermic agent held within the strip. Moisture within the skin or externally applied water penetrates the strip and will react with the agent to cause an increase in temperature. Subsequently this increase in temperature will induce a color change in the thermochromic substance.

  • Patent number: 6106857
    Abstract: A cosmetic product is provided for removing keratotic skin plugs. The product is a strip sealed for storage having from 0.0001 to 2% fragrance within the atmosphere of the sealed pouch. The strip includes a flexible substrate sheet onto which a composition containing an adhesive polymer is deposited. Fragrance is immediately available upon opening the pouch. Since fragrance is invested on outer surfaces of the strip, a user can immediately smell the scent upon the application of the strip to the nose or other facial areas. There is no longer dependence for release of fragrance held within the adhesive polymer composition.
