Abstract
A wiping article is provided which includes an effervescent cleanser composition held within a sachet, at least one wall of the sachet including at least one pleat. The presence of pleats allows expansion room within the sachet to accommodate effervescent action. It also results in an ergonomically pleasant pillow configuration. Advantageously, the sachet is formed of two sheets with the second sheet being relatively more rigid than the first sheet and non-pleated which permits easier graspability by a user's hand. Additionally, at least one of the sheets should be water permeable. In a preferred embodiment, the effervescent composition is an intimate mixture of an acid material such as citric acid and an alkaline material such as sodium bicarbonate. Water contact causes the combination to effervesce. Skin benefit agents may be included within the composition.
