Softener composition

摘要

The present invention provides the softener composition containing the specific quaternary ammonium salts (I) and (II) each having a bis(polyalkoxyalkanol) structure, represented by the formulae (I) and (II) respectively, at a weight ratio of (I):(II) of 50.1:49.9 to 99.99:0.01.

1. A method for softening a fiber product, said fiber product being selected from the group consisting of clothes and bedclothes, comprising treating the fiber product with a composition comprising a quaternary ammonium salt (I) represented by formula (I) and a quaternary ammonium salt (II) represented by formula (II) at a weight ratio of the quaternary ammonium salts (I) to (II), (I):(II), of 50.1:49.9 to 99.99:0.01: wherein, R1 and R2, which may be the same as or different from each other, represent a hydrocarbon group having 11 to 23 carbon atoms; R3 and R4, which may be the same as or different from each other, represent a hydrocarbon group having 1 to 4 carbon atoms that may have a hydroxy group; k and 1, which may be the same as or different from each other, represent an integer showing the mole number of added oxyethylene group ranging from 1 to 4; and X− represents an anion; wherein, R5 and R6, which may be the same as or different from each other, represent a hydrocarbon group having 11 to 23 carbon atoms; R7 and R8, which may be the same as or different from each other, represent a hydrocarbon group having 1 to 4 carbon atoms that may have a hydroxy group; m and n, which may be the same as or different from each other, represent an integer showing the mole number of added oxyethylene group ranging from 5 to 10; and X′− represents an anion, wherein the composition further comprises an inorganic or organic salt other than the quaternary ammonium salt (I) or (II).
