Abstract: The method of cleaning hair between shampoos which comprises rubbing the hair with a sheet-like substrate that has been treated to make it electronically attractive to hair soil in the presence of an aqueous liquid in a moistening amount.Means for cleaning hair between shampoos comprising a sheet-like substrate treated to make it electronically attractive to hair soil and moistened with a cleaning liquid. The substrate is preferably a flexible, absorbent, organic, fibrous sheet having satisfactory wet strength properties such as non-woven fabric and wet strength paper rendered electronically attractive to hair soil by the presence of a cationic organic polyelectrolyte, e.g., by incorporation in a sheet during or impregnation of a sheet after manufacture. The cleaning liquid is aqueous, preferably water and alcohol, usually absorbed in the substrate. Optionally and advantageously the substrate is folded into a compact pad and sealed within a moisture-proof envelope for convenience in carrying and use.

Abstract: A clear liquid synthetic organic heavy duty laundry detergent composition includes a condensation product of a higher fatty alcohol and polymeric ethylene oxide, fluorescent brightener, water and lower monohydric alcohol. The liquid detergent composition is biodegradable. The substantial proportion of nonionic condensation product detergent present is prevented from gelling by the alcohol and in turn, aids in solubilizing the fluorescent brightener. In preferred compositions, small proportions of sequestering agents e.g., nitrilotriacetate, and salt-forming base, e.g., monoethanolamine, are also present. Surprisingly, cleaning of soiled laundry is comparable to that obtained with the equivalent quantities of phosphate-containing built detergents, even when the present liquid contains much less than a normal building proportion of nitrilotriacetate or other substitute for the phosphate.
