Abstract
The present invention relates to a combination for surface treatment of a substrate, e.g. a nonwoven web, used in personal care product applications. The surface treatment combination not only provides adequate fluid handling properties, but also provides a topical delivery system effective in depositing a thin, tenacious and substantially continuous coating of a skin health benefit agent on skin by an aqueous emulsion mediated dissolution of the agent from a substrate with subsequent transfer and deposition onto the skin. Coatings of the skin health benefit agent on the skin resist removal, thereby preventing damage to the natural skin barrier and providing a protective barrier against chemically- and biochemically-induced skin damage.
