Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a softener composition for textiles.

[0002]

2. Description of the Related Art Conventionally, a quaternary ammonium salt or a tertiary amine acid salt having a long-chain alkyl group has been used as a softener.
