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 clothing, and particularly to a softener having excellent flexibility even in the presence of an anionic surfactant brought in from a washing cycle. It relates to a composition.

[0002]

2. Description of the Related Art Conventionally, most commercial products as household softening agents use a quaternary ammonium salt represented by di (hardened beef tallow alkyl) dimethylammonium chloride as a main component. However, with the spread of fully automatic washing machines in recent years, the anionic surfactant brought in from the washing cycle reduces the softening effect, and has a strong affinity with microorganisms from the viewpoint of environmental friendliness.
Grade salts came to be said to be unfavorable. Since all of these problems are caused by the strong cationic nature of the quaternary salt, amine compounds are being reviewed. However, conventional long-chain alkylamines such as methyldi (hardened tallow alkyl) amine have a low softening effect and are not sufficient.

[0003]

DISCLOSURE OF THE INVENTION The present invention provides a softener composition suitable for a fully automatic washing machine, while imparting flexibility to clothes.
