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. In the third embodiment, skin mildness and especially skin moisturization are significantly enhanced by the detergent bar compositions comprising the combination of the specific polyol ester with oil and/or humectant.
