• Shampoo formulations have been previously developed and employed in the cleaning of textile fabrics, including pile fabrics of the type normally found in rugs and carpeting. Many of the prior shampoo formulations involve the use of detergent materials in aqueous or solvent mediums, in which dirt and soil are removed by normal detergent action. Others involve formulations that are applied dry or damp to the touch to the cleaning surface on which soil and dirt particles are, in effect, loosened and removed by mild detergent action. Loosened particles are usually thereafterabsorbed on relatively large particles of filler material and subsequently vacuum drawn from the cleaning surface.
• the present invention provides a shampoo formulation that is simply and easily applied, highly efiicient in cleaning and shampooing action and'is characterized by cooperation between components to inhibit resoil on the shampooed area.
