Description

  The present invention relates to an effervescent tablet bath composition.

  Conventionally, a bath composition containing a carbonate and an organic acid is widely known as an excellent bath agent because the bubble of carbon dioxide gas is generated in the bath water, and the carbon dioxide gas exerts a blood circulation promoting effect. I have. Further, when an oil component is further added to such a bath agent, not only a warm bath effect but also a moisturizing effect and a skin care effect can be enhanced, and various bath agents containing these compounds have been developed.

  For example, Patent Literature 1 discloses various dosage forms such as granules, tablets, and liquids containing an oil component containing 60% by mass of a specific fatty acid ester and a specific nonionic surfactant in addition to a carbonate and an acid. A bath agent that can be exhibited is disclosed, and attempts have been made to moisturize the skin after bathing and impart a smooth feel by stably emulsifying an oily component. Patent Literature 2 further discloses a carbon dioxide gas generator such as a carbonate and an acid, a fatty acid and a fatty acid glyceride having a total content of 0.1 to 10% by mass, and a nonionic surfactant in a specific mass ratio. The present invention discloses a bath agent composition for bathing, particularly to enhance the feeling of warming during bathing.

  On the other hand, Patent Document 3 discloses a granulated product containing an organic acid having a specific particle size, 0.1 to 30% by mass of an oily component, and 6 to 30% by mass of a water-soluble binder. It also describes that the granulated product can be used as an intermediate for producing a bath agent, and that when formed into tablets, the effect of suppressing the exudation of oily components is enhanced.

  However, in order to obtain a tablet having a further enhanced moisturizing effect, the bathing agent described in Patent Document 1 described above tends to generate capping as the content of oily components, particularly fatty acid glycerides, is increased. There is a possibility that the lockability is reduced. Further, even in Patent Document 2, no specific study has been made on making some components into a granulated product, and even if the granulated product in Patent Document 3 is used, it is still good. It is not known whether tablets having both a good moisturizing effect and high tableting properties can be obtained.

  Accordingly, the present invention relates to an effervescent tablet-type bath composition that can effectively suppress capping and the like and exhibit high tableting properties while maintaining a good moisturizing effect.

  The present inventor has studied variously, together with a high content of a water-soluble polymer, a granule containing an oily component containing a high content of fatty acid glyceride, and a combination of a carbonate and an organic acid, It has been found that an effervescent tablet-type bath composition capable of exhibiting excellent tableting properties while maintaining a good moisturizing effect can be obtained.
