Abstract

The present invention is directed to a disposable article that contains a plurality of substrate layers. The article is selected from the group consisting of pad sized articles, grip sized articles, sheet sized articles and combinations. These articles have a cleansing composition associated with the substrate layers. The articles provide effective cleansing benefits to the skin and hair in a convenient, inexpensive, and sanitary manner. The articles of the present invention also have superior thickness. Additionally, the article has increased rigidity while at the same time is flexible. The increase in rigidity and thickness provides for an article that does not crush or crumple during use. The article of the present invention can also provide a therapeutic or aesthetic benefit without the need for a separate benefit providing product.
