2. Description of the Related Art Conventionally, most commercial products as household softening agents use a quaternary ammonium salt represented by di (hardened tallow alkyl) dimethylammonium chloride as a main component. In some cases, poor dispersion in water occurred, and the softening base unevenly adhered to the cloth, resulting in uneven softness, and problems such as gel-like substances adhering to fibers. For this reason, JP-A-52-1
As disclosed in Japanese Patent No. 148295, attempts have been made to improve the dispersibility in water, but it has been insufficient. Furthermore, since the number of fully automatic washing machines has increased in recent years and the opportunities for automatically adding a softening agent have increased, a composition having good dispersibility in water has been further desired.
