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.

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.

The present invention relates to bar compositions comprising a mixture of higher melting point and lower molecular weight (100 to about 1400) lower melting point polyalkylene glycol(s) in which use of the lower molecular weight polyalkylene glycol or glycols allows enhanced rates of extrusion from the plodder.

Mild bar compositions comprising blends of higher melting point

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.

An improved high-internal-phase emulsion having increased stability under conditions of long term storage at elevated temperatures and freeze-thaw conditions, methods for preparing and stabilizing said emulsions and cosmetic preparations based thereon are disclosed. The improvement comprises incorporating into said emulsion an amount sufficient to increase the stability of said emulsion of an electrolyte contained in the aqueous phase of the emulsion.
