• liquid detergent compositions of this invention are substantially anhydrous or essentially non-aqueous compositions which, when brought into contact with Water, as in connection with the shampooing of hair, evolve a gas which, in turn, in combination with the detergent formulation, causes a mechanical action leading to exceedingly large amounts of foams or suds.

• the liquid detergent compositions of this invention comprise (a) a substantially water-insoluble compressible gas, (b) a Water-soluble solvent for said compressible gas which lowers the vapor pressure of the resultant solution to a point at which said solvent solution of said compressible gas can be maintained at ambient temperatures in conventional non-pressurized containers, (c) a watersoluble anionic detergent, particularly a sulfated or sulfonated synthetic detergent, and (d) an alkanolamide, with or without certain supplemental ingredients.

• precipitates on occasion form on standing of the liquid detergent compositions over a period of time. While such precipitates do not have any significant adverse effect on the foaming properties of the liquid detergent compositions, it is distinctly preferred to avoid their formation for reasons of esthetics in packaging and otherwise. It has been found that good inhibition of such formation of precipitates is effected by the inclusion in the compositions of small proportions of water-soluble organic acids such as malic acid, citric acid, tartaric acid, gluconic acid, and the like. Generally, about 1% of such acids, based upon the weight of the finished liquid detergent composition, is sufficient, but the quantity may be somewhat less or somewhat more and it will ordinarily be unnecessary to exceed amounts of the order of about 2%.
