NOVELTY - Solid fragrant agent comprises fragrance, solid glue, solubilizer, preservative and water. The solubilizer is chosen from polyoxypropylene fatty alcohol ether and polyoxyethylene fatty alcohol ether, preferably 12-13C alkyl polyoxyethylene ether. The solid glue is chosen from polyvinyl alcohol, hydroxypropyl methylcellulose and modified cellulose. The preservative is mixture of dimethylol dimethyl hydantoin (DMDMH) and 3-iodine-2-propenyl-butylcarbamate (IPBC).    USE - The solid fragrant agent is useful as air freshener for promoting soberness, relieving fatigue and resisting melancholy.    ADVANTAGE - The solid fragrant agent is environmentally-friendly, safe and non-toxic as it is obtained from natural substances, and provides fragrance for 3-5 days.    DETAILED DESCRIPTION - Solid fragrant agent comprises (in %mass): fragrance (0.75-1.5), solid glue (0.5-1.5), high-efficiency solubilizer (8-10), preservative (0.4-0.6) and distilled water. The solubilizer is chosen from polyoxypropylene fatty alcohol ether and polyoxyethylene fatty alcohol ether, preferably 12-13C alkyl polyoxyethylene ether. The solid glue is chosen from polymer of polyvinyl alcohol, hydroxypropyl methylcellulose and modified cellulose. The preservative is mixture of dimethylol dimethyl hydantoin (DMDMH) and 3-iodine-2-propenyl-butylcarbamate (IPBC). The fragrance comprises (in wt.%): components chosen from lavender oil (22-30), rosemary oil (8-16), Eucalyptus oil (3-10), thyme oil (1-6), peppermint oil (8-15), spearmint oil (2-8), anise oil (8-16), rice bran oil (2-5), clove oil (1-6), lemon oil (8-16), bay leaf oil (2-5), benzeneacetaldehyde (1-3), geraniol oil (1-4), daphne seed oil (1-5), cinnamon oil (0.1-1) and antioxidant (1-2). The antioxidant is 2,6-di-tert-butyl-p-cresol (BHT). An INDEPENDENT CLAIM is included for method for preparing the above-cited agent, which involves (a) preparing the fragrance by adding components of the fragrance to container and uniformly stirring the obtained mixture for 15 minutes, (b) heating solubilizer at 55-60 degrees C for 15 minutes, adding the fragrance to the heated solubilizer, uniformly stirring the obtained solution for 5-10 minutes and naturally cooling the solution at room temperature, (c) adding distilled water to container, adding solid glue to the container, heating and stirring the obtained mixture at 95-90 degrees C for 20-30 minutes until solid content is dissolved, and stirring and cooling the obtained solution to 60 degrees C for obtaining gel, and (d) adding preservative to the gel, naturally cooling the gel to 40-50 degrees C, slowly pouring the solution obtained in step (b) to the gel, stirring the gel for several minutes at 30-40 degrees C, pouring the obtained agent into mold, and naturally cooling the mold to normal temperature.
