2. Description of the Related Art Conventionally, soaps have been widely used in cleansing foams, body shampoos, shampoos and other cleaning agents for the purpose of improving foaming and foam quality. Of these, the most frequently used are alkali metal salt soaps such as sodium and potassium fatty acids, which have the advantages of low cost, good lather, and creamy foam. On the other hand, however, there were drawbacks such as poor foaming in neutral, having a squeaky feeling and a tight feeling after use.

[0003] In addition, soaps based on fatty acids such as triethanolamine and lysine, which are weak bases, have been used in consideration of foaming and squeakiness near neutrality. There are problems such as deterioration and difficulty in obtaining a refreshing feeling, low melting point (craft point), and inability to mix with solid products.

[0004]

SUMMARY OF THE INVENTION The present inventors have conducted intensive studies in view of the above circumstances, and as a result, have found that N-methyltaurine alkali metal salt of a fatty acid or N-methyltaurine organic alkali salt is blended as an essential component. Agent composition, foaming, foam quality is good, less pH dependency of foaming,
It was found to be superior to the conventional art in that it did not have a squeaky feeling or a tight feeling and did not give off a bad odor. However, although such a composition exhibits properties suitable for a solid or liquid dosage form, it is not suitable for a paste-like dosage form which is preferred for a face wash or the like because of its good use properties such as water solubility and foaming. Had disadvantages.

The inventors of the present invention have conducted intensive studies to achieve the above technical problems, and as a result, have found that N-methyltaurine salt of fatty acid, alkali metal salt of fatty acid or triethanolamine salt of fatty acid, and polyhydric alcohol are used. The formulated detergent composition has a paste-like appearance and is found to be excellent in use properties such as good water solubility or good foaming,
The present invention has been completed.

An object of the present invention is to provide a detergent composition which has a paste-like appearance and is excellent in use characteristics such as good water solubility or good foaming.
