  • 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: 5520840
    Abstract: The present invention relates to synthetic detergent bars comprising 10-60% by wt. synthetic detergent surfactant; 10-60% of a water soluble structuring of water soluble structurant of MP between 40.degree. to 100.degree. C.; and 5-50% by wt. of a water-insoluble structurant of MP between 4.degree.--100.degree. C. Unexpectedly, applicants have found that addition of "true" water soluble starches yields processing and composition advantages.
