  • Publication number: 20050069305
    Abstract: A vapor dispensing device having a high transverse loading stability includes a relatively low profile with respect to the supporting wall or electrical receptacle such that the frequency and impact of accidental physical contact with the device are appropriately reduced. To achieve a low profile, the housing of a vapor dispensing device is designed such that the distance from the outlet face of the wall receptacle to a worst-case transverse loading point (dL) is less than the distance from the plug to a worst-case support point (dS).

  • Patent number: 6114291
    Abstract: The present invention relates to skin cleansing bar composition in which polyalkylene glycols of very specific molecular weights are used to define compositions which are mild, foam well and provide consumer-desired sensory profiles. A significant amount of these specific PEGs must be incorporated into the bar to deliver these desired effects. To properly process such a bar composition, the cast-melt method is the preferred technique.

  • Patent number: 6074998
    Abstract: The present invention relates to solid detergent compositions generally comprising anionic/amphoteric/nonionic surfactant systems. Addition of specific polyol esters wherein the melting temperature and HLB are specifically defined has been found to remarkably enhance the oil/humectant structuring and releasing capabilities of a skin cleansing bar. In a second embodiment, the invention relates to a method for enhancing the bar's capability of including high levels of oil and/or humectant by carefully balancing the polyol ester's weight ratio to the oil and/or humectant. In the third embodiment, the invention relates to a method of enhancing the bar's capability of incorporating high levels of oil and/or humectant and delivering the oil and/or humectant for skin benefit by carefully balancing the polyol ester's weight ratio to the other costructurants such as PEG 8000 and fatty acid.

  • Patent number: 5994281
    Abstract: The present invention relates to personal wash bar compositions, particuly compositions comprising (1) lathering anionic surfactants (e.g., sodium acyl isethionate or fatty acid soap); (2) specific solid, less hygroscopic amphoteric surfactants (e.g., disodium N-lauryl iminodipropionate). The invention relates to the incorporation of significant levels of said solid amphoteric surfactant into the specific bar compositions to achieve superior skin mildness and bar user properties. The invention especially addresses the advantages of using solid, less hygroscopic amphoteric surfactants to reduce the processing difficulties in extrusion and modified extrusion processes.

  • Patent number: 5981464
    Abstract: The present invention relates to novel chip compositions containing specific polyol ester as the major carrier for liquid skin benefit agents. Addition of specific polyol esters wherein the melting temperature and HLB are specifically defined has been found to remarkably enhance the oil/humectant structuring capability of a skin cleansing bar. Such a polyol ester also permits the liquid benefit agents to be released into a personal wash liquor and then to be delivered to skin via personal wash. In a second embodiment, the invention relates to a method for enhancing the bar's capability of including high levels of oil and/or humectant by applying the adjuvant technology. That is, by coextruding and stamping the mixture of chips containing skin benefit agents and base chips containing a surfactant system, high levels of oils and/or humectants can be incorporated into solid toilet bars by standard extrusion technology.

  • Patent number: 5935917
    Abstract: Novel chip compositions comprise specifically defined carriers; benefit agent; and thickening agent (e.g., fumed silica). Use of chips comprising excess of these carriers 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: 5817609
    Abstract: The present invention relates to personal wash bar compositions comprising hydrophobic, low viscosity (less than 1000 cp) emollient agents which have been specifically pre-thickened with defined polymer composition. Use of the specific thickeners allow incorporation of the low viscosity oil (viscosity less than 1000 cp) in the personal wash compositions to deliver enhanced skin benefits and desired user properties without compromising foaming and bar processing.
