It contains eugenol, isoeugenol, methyl-eugenol or an isomer thereof. A method for removing orthodontic fixtures adhered with a dental cement or resin to the enamel surfaces of teeth from these surfaces by contacting the dental cement or resin with a composition containing eugenol.

The invention relates to a preparation method of a sexual attraction slow-release formulation for fruit flies. By weight parts, the preparation method comprises the following steps: (1) dissolving 1-50 parts of methyl eugenol or cue-lure and 0.1-20 parts of toxic ingredients in 100 parts of organic solvent, for standby application, wherein the toxic ingredients include trichlorphon, abamectin, and emamectin benzoate or chlopyrifos; (2) stirring 1000 parts of polyatomic alcohol with molecular weight smaller than 3000 for 15-100 minutes at the temperature of 35-75 DEG C and vacuum degree of minus 0.1MPa; and (3) adding the standby solution of the step (1) in the polyatomic alcohol of the step (2), continuing stirring to be uniform, then adding 3000-10000 parts of isocyanate, continuing stirring for 120 minutes at the temperature of 35-75 DEG C and vacuum degree of minus 0.1MPa, stopping vacuum-pumping, and then obtaining pasty sexual attraction slow-release formulation for the fruit flies. The sexual attraction slow-release formulation prepared by the method is mainly used for monitoring fruit fly population density or preventing and controlling fruit fly pests in large area.

An antimicrobial packaging material for food stuffs containing from 0.05% to 1.5% by weight of a natural essential oil. The oil can be selected from primarily linalool and / or methylchavicol, but also from one or more of citral, geraniol, methyl cinnamate, methyl eugenol, 1,8-cineole, trans-a-bergamotene, carvacrol and thymol blended with one or more polymers selected from ethylene vinyl alcohol copolymer, polyacrylates, including ethyl acrylate methyl methacrylate copolymers, lonomers, nylons and other hydrophilic polymers or polymers possessing functional groups capable of partially anchoring the additives and the blender mix is coated onto the food contact face of a food grade packaging film or incorporated into a food grade packaging film. A binding agent such as polyethylene glycol is added to the blend to improve the retention of the volatile oil in the polymer during processing. This material has no regulatory limitations and, at the referred concentrations, does not form detectable off-flavors.
