Abstract

PROBLEM TO BE SOLVED: To obtain a fragrant agent capable of rapidly conferring fragrance to a space or altering such fragrance. SOLUTION: This fragrant agent is obtained by including 0.5-30.0 wt.% of a perfume, 5.0-95.0 wt.% of an exothermic substance which generates heat by adding water thereto, and 5.0-70.0 wt.% of powder. When water is added to this agent, heat is generated instantaneously to effect diffusion of fragrance.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fragrance, and more particularly to a fragrance capable of rapidly imparting or changing a scent to a space.

[0002]

2. Description of the Related Art Conventionally, indoor fragrances have been used in a liquid state by dissolving or emulsifying in water using a combination of a fragrance and a surfactant, or using agar or gelatin. Use by gelling with a polymer. It is used in a container designed to moderately evaporate the contents, so it has a mild scent. However, at home, for example, when a customer comes, when a friend comes, or when one wants to change the mood with a scent, it is convenient if a fragrance can be added or changed instantly in the room.

[0003] The present invention has been made in view of such conventional circumstances, and an object of the present invention is to provide a fragrance capable of instantaneously imparting or changing indoor scent.

[0004]

Means for Solving the Problems The inventors of the present invention have conducted intensive studies to solve the above-mentioned problems. As a result, if a heat-generating substance which generates heat by adding water is added, the whole system is added by adding water when used. Generated heat, and found that the volatilization of the fragrance component was promoted and that the scent could be rapidly applied to the space, and the present invention was completed.

That is, according to the present invention, 0.5 to 30.0% by weight of a fragrance, and 5.0 to 9 exothermic substances which generate heat by adding water.
A fragrance characterized by containing 5.0% by weight and 5.0 to 70.0% by weight of powder.

As the flavor component used in the present invention, any of animal-, plant-, and mineral-based natural flavors and synthetic flavors can be used. The amount of the fragrance is such that a sufficient scent can be obtained as an indoor fragrance product, but is generally 0.5 to 30.0% by weight, preferably 5.0 to 2% by weight.
