Description

  The present invention relates to an effervescent compression molding type bathing agent that has a good scent immediately after being dissolved in bath water, that is, can feel a good scent immediately after a bather takes a bath.

In recent years, it has become popular to add bathing agent to bath water for the purpose of refreshing the mood of bathing by adding aroma and color to bath water, improving metabolism and improving coldness, etc. Various forms such as bath salts, tablets, and liquids are sold. Among them, bathing agents containing a carbon dioxide generator that combines carbonates and acids expand blood vessels by carbon dioxide generated in the bath water and promote metabolism, recovery of fatigue, etc. The effect is expected.
In addition, as one of the important effects expected as a bath agent, there is an aromatherapy effect by a fragrance, and it is important to stably maintain the fragrance in order to enhance these effects during bathing. Therefore, in Patent Document 1, as a technique for enhancing the fragrance of the bath agent, it is a granular bath agent having a small particle size and a large surface area, and Patent Document 2 has a specific amount of liquid component, It has been reported to be a compressed formulation with a specific average surface area.

  Until now, as a bathing agent combining a carbonate and an acid, in order to easily dissolve the generated carbon dioxide gas, a bathing agent of a dosage form such as a solid compression preparation such as a tablet or a tablet submerged in bath water has been widely used. However, since it sinks in bath water, it cannot be said that the fragrance is good, and there is a problem that if the fragrance component is contained in order to improve the fragrance, the preparation stability is deteriorated.

  It is an object of the present invention to provide an effervescent compression molding type bath agent that has a good scent immediately after being dissolved in bath water, that is, a bather can feel a good scent immediately after taking a bath. It is said.

  The present inventor combines component (a) a fragrance compound having a carbonyl group and a boiling point in the range of 200 to 400 ° C. in combination with (b) carbonate and (c) succinic acid, and compression compression molding. The present inventors have found that the above problems can be solved by using a mold bath, and have completed the present invention.

The gist of the present invention is specifically as follows.
1. It contains the following components (a) to (c), and 0.001 to 5% by weight of component (a) and 20 to 55% by weight of component (c) with respect to the total weight of the foamable compression mold bath % Foamable compression mold bath (however, foamable compression mold bath containing adipic acid or fumaric acid , 1-methyl-1- (5-methyl-5-ethyltetrahydrofuran-2-yl) ethanol Or a foamable compression molding bath containing the acyl ester compound as a fragrance and a sulfur-containing amino acid compound having a polyhydroxyalkyl group having 3 or more hydroxyl groups
Except foaming compression mold bath ).
(A) benzyl benzoate, methyl-di hydro jasmonate Nate, amyl cinnamic aldehyde, methyl ionone, lilial, any one or more flavoring compounds of damascone (b) carbonate, and (c) succinic acid

According to the present invention, a component (a) a fragrance compound having a carbonyl group and having a boiling point in the range of 200 to 400 ° C. is combined with (b) carbonate and (c) succinic acid to obtain a foamable compression. By using a mold-type bath agent, it is possible to provide a bath agent with good fragrance immediately after dissolution in bath water.
That is, since the foamable compression molding bath of the present invention is excellent in fragrance immediately after being dissolved in bath water, the bather can feel a good fragrance immediately after bathing, and an aromatherapy effect is obtained. It is done. Moreover, since the foamable compression molding type bath agent of the present invention is also excellent in foaming properties, effects such as blood circulation promotion and fatigue recovery can be obtained, and a high bathing effect can be obtained.
