Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a softener composition for imparting flexibility to fibers and clothes, and particularly to a softener composition which is hardly affected by an anionic surfactant due to washing and has excellent flexibility. Regarding

[0002]

2. Description of the Related Art Conventionally, most commercial products for household softening agents use a quaternary ammonium salt represented by di (hardened beef tallow alkyl) dimethylammonium chloride as a main component. There is a problem in using it in the popular automatic washing machines. Since the fully automatic washing machine has a small bath ratio and a small number of rinses, the amount of anionic surfactant present in the bath during the softening treatment increases, and a quaternary ammonium salt having strong cationic property and an anion-cation complex are added. It has been found that the formation and softening effect is reduced. On the other hand, a method of using an amine having a slightly weak cationic property as a softener base is also known. For example, JP-A-52-05
Japanese Patent Publication No. 9796 discloses a composition using methyldi (hardened tallow alkyl) amine, but even this composition has a low softening effect and is not yet sufficient. Therefore, in softening treatment using a fully automatic washing machine, development of a softening agent having excellent flexibility is desired.
