Description of the Related Art Generally, laundry soap is a composition composed of a fatty acid salt and auxiliary components such as an antioxidant, a builder, a bleaching agent and a fragrance, and the fatty acid salt is greatly involved in the quality of the performance. . The fatty acid salt used for laundry soap is usually a composition of a plurality of types of fatty acid salt having 12 to 18 carbon atoms, and its composition determines performances such as foaming, oxidation stability and detergency. Solubility in water is one of the important performances required for laundry soap, but solubility in water is important especially in winter because it is often used at low temperature. In order to improve the solubility in water, it is advisable to increase the content of the fatty acid salt having a short carbon number in the fatty acid salt composition. However, since the detergency of a fatty acid salt having a short carbon number is low, excessive use causes a problem of low detergency. In order to solve this problem, for example, Japanese Patent Application Laid-Open No. 54-16513 discloses a technique using a salt of a branched saturated fatty acid. However, even such laundry soap does not have sufficiently satisfactory solubility in water and detergency. It is also known that the content of unsaturated fatty acid salt in the fatty acid salt composition may be increased in order to increase the solubility in water. But,
Since unsaturated fatty acid salts have poor oxidative stability, excessive use thereof causes a bad odor, which is a problem. Antioxidants are often added to prevent bad odors,
Antioxidants can cause the coloring of soaps and their use is limited. As described above, at present, there is no fatty acid salt composition capable of simultaneously satisfying the solubility in water, the detergency, and the low odor required for laundry soap.
