Natural product complexes are described that are protected from the harmful effects of microorganisms, including one or more natural products, one or more thermoplastics and antifungal agents. The complex is protected from climate and color formation by incorporating at least one light stabilizer and at least one compound selected from the group consisting of oxides, hydroxides or silicates of Ca, Mg, Al and Zn. The light stabilizer is selected from the group consisting of ultraviolet absorbers and hindered amines. The metal oxide is for example CaO. Natural products are for example wood flour, flax, hemp, jute, sheep or rice hulls. The thermoplastic resin is for example polyethylene or polypropylene. Antifungal agents and coadditives are incorporated by melt processing methods such as extrusion, co-kneading, pull-trussion and injection molding. Antifungal agents are for example thiabendazoles. |
