Abstract

Abstract The invention provides novel compounds of formula ##STR1## in which R signifies a hydrocarbon radical of 5 to 22 carbon atoms, which may be substituted, R 1 and R 2 , which may be the same or different, each signifies a hydrogen atom or a lower alkyl radical which may be substituted, provided that at least one of R 2 and R 1 or the R 1 's signifies hydroxyalkyl or carboxyalkyl, in which the alkyl radical contains 1 to 4 carbon atoms, or a radical of formula --CH 2 SO 3 - M + , --CH 2 --CH 2 --O) p H, --CH 2 --CH(CH 3 )O) p H, --CH 2 --CH 2 --CN or --CH 2 --CH 2 CONH 2 , p signifies 1 to 10, X signifies --CONH--, ##STR2## --O-- or --S--, m signifies 0 to 6, n or the n's, which may be the same or different when m is greater than 1, each signifies from 1 to 8, a signifies 0 or 1 and M + signifies hydrogen, an ammonium cation or an equivalent of a metal cation, and quaternary ammonium derivatives thereof, useful as textile finishing agents.
