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. A method of preparing the hair soil removing means comprises treating a suitable substrate to make it electronically attractive to hair soil, e.g., by incorporating in it a substantive cation active agent such as a polyelectrolyte and moistening the substrate with the cleaning liquid. An optional operation is sealing a so-treated and moistened sheet-like substrate within a moisture-proof envelope, preferably using a heat sealable laminate of metal foil, paper and polyethylene layers. Treated sheets of substrate and liquid, however, may be packaged separately and combined at the time of use by moistening the substrate or the hair prior to rubbing the hair with it.
