Abstract
An odor control layer for personal care products has a composition that has a PEG or PEG copolymer composition applied thereto. The layer can be placed in a personal care product, such as a diaper, training pant, absorbent under pant, adult incontinence product, or feminine hygiene product. Additional odor control layers may include silver nanoparticles and activated carbon compositions. In an alternative form, a single odor control layer includes the PEG composition and the activated carbon and/or silver nanoparticle compositions. A cleansing composition with PEG and possibly active carbon and silver nanoparticles may be combined with the personal care product to form a kit.
