Soft finishing agent

Claim 1

A soft finishing agent comprising the following di-long-chained quaternary ammonium salts (A) or (B): (A) di-long-chained quaternary ammonium salt which is represented by formula (I): ##STR8## (in which R 1 and R 2 independently represent alkyl groups having an average carbon atom content of 10-24 and are derived from a naturally occurring oil or fat, provided that at least R 1 or R 2 have an average carbon atom content of not less than 14, R 3 and R 4 independently represent alkyl or hydroxyalkyl groups each having an average carbon atom content of 1-3, benzyl groups, or groups represented by --(C 2 H 4 O) n H, wherein n denotes an integer of 1-3, and X represents a halogen or an alkyl sulfate having a carbon atom content of 1-3), and of which 5% by weight aqueous dispersion has a gel-liquid crystal transition point of not more than 20° C., or (B) di-long-chained quaternary ammonium salt which is represented by formula (II): ##STR9## (in which R 5 and R 6 independently represent alkyl or alkenyl groups having an average carbon atom content of 10-40, provided that at least R 5 or R 6 have and average carbon atom content of not less than 16, R 3 , R 4 an X have the same meanings as defined in formula (I)), and of which 5% by weight aqueous dispersion has a gel-liquid crystal transition point of not more than 30° C.
