あった。2. Description of the Related Art Conventionally, higher fatty acid salts have been used as a main component in solid detergent compositions typified by bath soap. However, higher fatty acid salts have a strong degreasing power and often have a tight feeling after use, and it has been pointed out that irritation to the skin is caused. Moisturizers such as polyhydric alcohols and plant extracts have been used to solve these problems, but sufficient effects have not been obtained because they run off during rinsing. Further, the higher fatty acid salt has a problem that foaming is hindered by the hardness of water or hot water used and soap residue is generated.

なかった。In order to solve these problems, studies have been made to add anionic surfactants, amphoteric surfactants and the like to higher fatty acid salts. For example, Japanese Patent Laid-Open No. 2-155992
JP-A No. 2-155996 discloses a hypoallergenic solid detergent comprising a combination of a higher fatty acid salt and sodium lauroylmethyl taurate, and JP-A-2-155996 discloses a hypoallergenic combination of a higher fatty acid salt and a betaine-type amphoteric surfactant. Solid detergents are disclosed. However, these compositions have a tendency to dissolve rapidly after repeated use, and have insufficient foamability, a feeling of tightness during rinsing, and a feeling of moistness after drying.

題があった。Further, a solid detergent composition containing a surfactant other than higher fatty acid salts as a main component is disclosed in JP-A-59-59.
In JP-A-152999, JP-A-8-27482 and JP-A-9-125100, a solid detergent composition containing an amino acid-based detergent component such as an acylglutamate or an acyl isethionate as a main component is further disclosed in JP-A 8-2
Japanese Patent No. 45981 discloses a solid detergent composition in which an N-acyl taurine salt is combined with a higher fatty acid or a higher alcohol. However, these compositions do not have sufficient hardness at the time of molding, have a rough texture, and rapidly dissolve when repeatedly used. Further, regarding the feeling of use, there are problems that a slimy feeling remains during cleaning and that a refreshing feeling cannot be obtained after cleaning.

ない。On the other hand, since the composition of Comparative Example 1 contains a large amount of the component a, sufficient hardness cannot be obtained at the time of molding and the texture is rough, and the sustainability of the foam is reduced. In addition, a slimy feeling remains after use, a refreshing feeling after washing is not obtained, and the dissolution collapses rapidly after repeated use. Since the composition of Comparative Example 2 contains a small amount of the component a, the foamability is lowered, and the composition has a tight feeling during rinsing, and a moist feeling after drying cannot be obtained. Since the composition of Comparative Example 3 contained a large amount of the component b, it had no fluidity and was difficult to mold. Further, the foaming property is lowered, and there is a feeling of tension during rinsing, and a moist feeling after drying cannot be obtained. Since the composition of Comparative Example 4 has a small content of the component b,
Not enough hardness can be obtained at the time of molding and the texture is rough,
A slimy feeling remains during use, and a refreshing feeling after washing cannot be obtained. It also dissolves quickly after repeated use. Comparative Example 5
Since the composition (1) has a large content of the component c, the foamability is lowered, and a slimy feeling during use remains, and a refreshing feeling after washing cannot be obtained. Since the composition of Comparative Example 6 has a low content of the component c, the foam quality is poor and the dissolution collapse is rapid during repeated use.
Since the composition of Comparative Example 7 contains a large amount of the component d, the foamability is lowered, the slimy feeling during use remains, and the refreshing feeling after washing cannot be obtained. Since the composition of Comparative Example 8 did not contain the component d, the preparation swelled during molding and cracked after cooling. It was also glossy and had a rough texture. Since the composition of Comparative Example 9 has a large total content of the components a and b, it retains a slimy feel during use, and disintegrates rapidly after repeated use. Since the composition of Comparative Example 10 has a small total content of the component a and the component b, a refreshing feeling after washing cannot be obtained. The composition of Comparative Example 11 had an a / b ratio of 5
Since it exceeds / 1, a slimy feeling during use remains, and a refreshing feeling after washing cannot be obtained. It also dissolves quickly after repeated use. The composition of Comparative Example 12 had an a / b ratio of 1/2.
Since it is below the range, the foamability is lowered, there is a feeling of tightness during rinsing, and a moist feeling after drying cannot be obtained. Comparative Example 13
Is a composition comprising an N-acyl taurine salt different from the component a of the present invention in which R 2 of the component a is a hydrogen atom and a higher fatty acid, but sufficient hardness cannot be obtained during molding and the texture is rough. A slimy feeling remains during use, and a refreshing feeling after washing cannot be obtained. In addition, it quickly collapses after repeated use. Comparative Example 14 is a composition in which the component a of the present invention is added to a higher fatty acid salt, but the foaming property is lowered in artificial hard water, there is a feeling of tightness during rinsing, and a moist feeling after drying cannot be obtained. ..
