Abstract
Abstract This invention describes improved methods for the incorporating of fragrance compounds or oil bouquets and/or topical antifungal or antibacterial agents, insect repellent compounds and certain odoriferous medicaments into polymeric or natural materials so that the fabricated product possesses the properties imparted by the additive or additives for a long period of time. The efficiency of incorporating these additives in the materials mentioned above is improved by the use of surfactants and the effectiveness and duration of the additive or additives in the fabricated product is enhanced by employing antioxidants and/or ultraviolet radiation absorbers.
