Description

Softener composition Technical field

The present invention relates to softener compositions. Background art

Conventionally, quaternary ammonium salts and tertiary amine salts having long-chain alkyl groups have been used as softeners. Attempts have also been made to incorporate an antimicrobial agent into the softener composition from the viewpoint of hygiene and deodorization of textile products. Japanese Unexamined Patent Application Publication No. Hei 10-51212 discloses a softener composition containing a water-insoluble quaternary ammonium salt as a softener and a water-soluble quaternary ammonium salt as an antibacterial agent. I have. Japanese Patent Application Laid-Open No. 7-36949 discloses a dilong chain alkyl (alkyl or alkenyl group having 6 to 24 carbon atoms which may be interrupted by an ether bond, an ester bond or an acid amide bond).
