Description

  The present invention relates to a bath agent composition.

  Conventionally, a bath preparation containing an organic acid and a carbonate is excellent in that carbon dioxide gas is generated in the bath water, and blood circulation is promoted by such carbon dioxide gas to enhance the warming feeling. It is widely known as a bath preparation. For example, Patent Document 1 discloses a granulated product containing an organic acid, a water-soluble binder, and a specific amount of a nonionic surfactant, and a granular bath agent composition containing a carbonate, and a bubble of carbon dioxide gas. It is a problem to bring a superior warm feeling after bathing by miniaturizing.

  Such a bath agent using a surfactant can be applied to products in the category of so-called “Bubble Bath”, which generates foam on the surface of the bath water along with the generation of carbon dioxide gas, resulting in a comfortable feeling of use. It is a useful technique. For example, Patent Document 2 discloses a powder bubble bath composition containing a granulated product containing a foamable surfactant, an organic acid and a water-soluble polymer, and a specific carbonate, The problem is to improve the foam sustainability on the surface of the bath water by making the foam finer and to give a good feeling of use. Patent Document 3 discloses a solid bubble bath composition containing a specific amount of a surfactant and an oil component in a specific amount ratio while containing carbonate and an acid in specific amounts. The challenge is to increase the feel of the foam on the surface and to give the skin after bath a moist feeling.
