Proposed is a bleaching composition for house cleaning which exhibits very high bleaching activity but is free from the problem of an unpleasant irritative odor. The composition comprises: (a) a water-soluble peroxide compound such as hydrogen peroxide; and (b) a compound as a bleaching activator represented by the general formula ##STR1## in which X.sup.1 is a monovalent group represented by the general formula

Peroxide bleaching compositions containing quanternary ammonium

The invention provides a novel and improved method for the preparation of a highly concentrated aqueous dispersion of a pearlescent agent, which is typically an ethyleneglycol di(fatty acid) ester, capable of forming very thin leaf crystals exhibiting pearlescence to be used for imparting pleasant appearance to detergents, toiletries, such as hair shampoos, hair rinses and others, and the like admixed therewith. The method is performed by solubilizing the pearlescent agent in an aqueous solution of a surfactant, at least a substantial amount thereof being in the state of middle phase liquid crystals, at or above the melting point of the pearlescent agent and succeedingly cooling the above obtained mixture to room temperature whereby to crystallize the pearlescent agent in situ while the state of the middle phase liquid crystals of the surfactant is kept substantially unchanged.

Method for the preparation of an aqueous dispersion of pearlescent agent

A detergent composition, suitable for use in washing vegetables and dishes and shampooing human hair, having both good detergency and little hand roughening action is presented. This detergent composition contains:

Detergent composition

A production process of a liquid detergent composition having both good detergency and little hand roughening action is presented. This liquid detergent composition can be produced by mixing an anionic surface active agent and a semi-polar nonionic surface active agent, each in the stage of an aqueous solution, and then, adding a specified arylsulfonic acid to this mixture in such a manner that the produced liquid detergent composition contains 6 to 25% by weight of the anionic surface active agent, 2 to 8% by weight of the semi-polar nonionic surface active agent and 0.2 to 3.0% by weight of the arylsulfonic acid.
