  • Patent number: 6187728
    Abstract: A composite article comprising a solid cosmetic formulation core, preferably of transparent glycerin soap, and a foamed polymer skin, preferably a sponge. The solid soap-core is preferably formulated to mimic the meat of a fruit such as an orange. The sponge-skin is preferably formulated to mimic the skin appropriate to the meat, for example, an orange peel. At least the meat and preferably also the skin part includes dyes and fragrances to impart the color and smell of the fruit being imitated. The composite article is produced either by forming the soap core, coating a sponge forming polymeric composition onto the soap core, and foaming and curing the coating to form a sponge skin on the soap core, or by first forming a hollow foamed polymer shell, introducing liquefied soap into the shell, and hardening the soap.

  • Patent number: 6106849
    Abstract: A "single-use" personal care product designed to replace conventional single use products such as small bars of soap, mini-bottles of shampoo, etc. A water soluble foamed polymer structure, such as produced by freeze drying acemannan derived from aloe vera, serves as the carrier for the personal care active ingredient, and provides the bulk to the structure. The dry foamed product has high void volume, good dimensional stability, high surface area, dissolves easily and completely upon exposure to water and hand mechanical action, and leaves no adverse residue on the skin. The product does not require bottling or complex wrapping, and is much more economical and environmentally friendly than the conventional single use products it replaces. The product can be conveniently carried in a purse or pocket, so that a consumer need never be without his/her favorite personal care products.

  • Patent number: 5981451
    Abstract: Novel compositions are prepared in a non-molten process. In particular, compositions comprise optional fillers with both soap and high levels of synthetic surfactants. When high levels of soap and surfactant are normally used in such process, there is a significant "grittiness" problem. Pre-processing the surfactant containing chip (e.g., "DEFI" chip) has been unexpectedly found to remedy this problem.

  • Patent number: 5972859
    Abstract: Novel chip compositions comprise alkylene glycol, benefit agent and thickening agent (e.g., fumed silica). Use of chips comprising excess of alkylene glycol over benefit agent and thickening agent has been found to allow significant deposition of benefit agent without compromising processing. In a second embodiment, the invention comprises bar compositions comprising mixtures of the chips of the invention and chips containing defined surfactant systems. A process for forming the chips of the invention and a method of enhancing deposition without compromising processing using the chips of the invention are also disclosed.

  • Patent number: 5972860
    Abstract: A framed soap composition comprises (a) from 20 to 50% by weight of a fatty acid soap, (b) from 1 to 15% by weight of a nonionic surfactant, and (c) from 0.1 to 5% by weight of an inorganic salt. A framed soap composition incorporated with air bubbles is produced by melting a mixture containing these components while heating the mixture in the presence of water, subjecting the resultant molten material to aeration treatment to incorporate air bubbles, and pouring the resultant molten material incorporated with air bubbles, into a frame followed by cooling to harden the molten material.

  • Patent number: 5962382
    Abstract: The present invention relates to a clear colorless soap bar with superior mildness, lathering and discoloration resistance. The clear colorless soap consists of a blend of C12-C18 fatty acids neutralized with sodium hydroxide (NaOH) and triethanolamine (TEA). Excess TEA acts as a co-solvent and is responsible for clarity of the soap bar. The bar also contains a branched chain acid such as isostearic acid to break up crystallinity and add to product clarity. Low color and color stability are obtained by removing unsaturated fatty acids, and by the use of antioxidants (BHT and Vitamin E). Low levels of C6 to C10 fatty acids provide exceptional mildness.

  • Patent number: 5908707
    Abstract: Wet-like cleaning wipes and similar articles are described. These wipes comprise a carrier that provides controlled fluid absorbency and an emulsion applied to the carrier. The emulsion comprises a continuous external lipid phase and a polar (e.g., water) internal phase. The emulsion is sufficiently brittle that it ruptures when subjected to low shear pressures during use to release the dispersed polar phase. The carrier allows the released internal phase to initially reach and remain on the surface being cleaned, but then absorbs the material at the end of the wiping process.
