Abstract
Odor reduction for products such as disposable diapers and training pants, sanitary napkins and tampons, incontinent products, and medical dressings is obtained by the use of an internal additive for synthetic polymers or an external additive for natural polymers. Results are further enhanced by the use of a surfactant especially in the case of synthetic polymers. Webs, fibers and films find uses as components of the described products and are effective in absorbing odors such as ammonia, triethylamine, indole and skatole, for example, which are commonly found in body fluids like sweat, menses, urine and fecal matter.
