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.

Claims

2. A method according to claim 1 wherein the incorporated odorant additive is an insect repellent.

3. A method according to claim 2 wherein the insect repellent is incorporated into a necklace, wristlet or anklet garment article manufactured from said molded or extruded polymers, said articles when worn on exposed body parts of human subjects in a mosquito-infested area afforded significant protection from mosquito attraction and bites.

4. A method according to claim 2 wherein the insect repellent is selected from the group consisting of 2-ethyl-1,3-hexandiol, dimethyl-phthalate,N, N-diethyl-m-toluamide, and butyl mesityl oxide.

5. A method according to claim 1 wherein the incorporated odorant additive is a pleasantly odiferous medicament.

6. A method according to claim 4 wherein the pleasantly odiferous medicament is selected from the group consisting of menthol, camphor and methyl salicylate.

7. A method according to claim 1 wherein a nonodorous antimicrobial agent other than the quaternary ammonium surfactant is also incorporated into the articles.

8. A method according to claim 6 wherein the antimicrobial agent is hexachlorophene.

9. A method according to claim 1 wherein the incorporated odorant additive is a fragrance compound or oil bouquet.

10. A method according to claim 1 wherein the article is manufactured by injection molding.
