Abstract
The invention relates to a cloth that can function as a moisturizing cleanser. When the cloth is moistened with water, it works up into a warm, sudsy cleansing lotion that feels great and works well as a facial cleansing cloth. The cloth contains water, at least one surfactant and at least one hydrophilic polymer.
Claims54
A cleaning article comprising a substantially dry substrate selected from the group consisting of a pad or a sheet, which substantially dry substrate is impregnated or coated with a dried-down composition that comprises a hydrophilic polyurethane polymer, at least one surfactant and water, wherein prior to drying down the composition, the composition is impregnated into or coated onto the substrate as a wet mixture comprising
- (a) between about 0.01% and about 90% of a hydrophilic polyurethane polymer;
- (b) between about 0.05% and about 90% of at least one surfactant;
- and
- (c) between about 10% and about 85% water,
- where percentages are based on the total weight of the composition prior to drying down.

A method of making a cleaning article comprising the steps of:
- (a) forming a wet mixture by mixing water, at least one surfactant, and a hydrophilic polyurethane polymer, and
- (b) impregnating and/or coating a substrate with the wet mixture in such manner that the wet mixture does not form a hydrophilic foam,
- (c) drying the impregnated and/or coated substrate.
A method for cleansing body or face comprising the steps of
- (a) wetting a cleaning article comprising a substantially dry substrate selected from the group consisting of a pad or a sheet, which substantially dry substrate is impregnated or coated with a dried-down composition that comprises a hydrophilic polyurethane polymer, at least one surfactant and water, wherein prior to drying down the composition, the composition is impregnated into or coated onto the substrate as a wet mixture comprising
- between about 0.01% and about 90% of a hydrophilic polyurethane polymer;
- between about 0.05% and about 90% of at least one surfactant;
- and
- between about 10% and about 85% water,
