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. 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.
