Abstract
Abstract A liquid softener composition comprises water and an amidoamine compound (a) obtained by condensation reaction of a di- or triamine of the general formula (I) with a fatty acid of the general formula (II), or a neutral salt of the amidoamine compound with an inorganic or organic acid: R¹NH(C m H 2m NH) n H (I) wherein R¹ represents a straight chain or branched, saturated or unsaturated hydrocarbon group having 8 to 24 carbon atoms, R² represents a straight chain or branched, saturated or unsaturated hydrocarbon group having 7 to 23 carbon atoms, m represents 2 or 3, and n represents 1 or 2.
