Abstract (en)

[origin: WO9602622A1] A liquid detergent composition containing surfactant, electrolytes and 0.01 - 5 % of at least one hydrophilic copolymer represented by formula (I) or (II), where x, y, z, a, and b are integers and N is an alkali metal, or hydrogen and the monomer units are in random order. (x + y):z is from about 5:1 to 1000:1, and y can be any value ranging from zero up to the maximum value of x, R1 = H or CH3, R2 = COOM, OCH3, SO3M, O-CO-CH3, CO-NH2, R3 = CH2-O-, CH2-N-, COO-, -O-, (i), CO-NH-, R4 = -CH2-CH2-O, R5 = alkyleneoxy group, preferably propyleneoxy or butyleneoxy groups, with the provision that, if b is different from zero, the values of a and b in the sidechain are such that the combined weights of R4 and R5 are such that the monomer has a solubility of at least about 500 grams/liter in water; formula (II), where R6 = (a) or (b) or mixtures of both; wherein in formula (II), x, y, z, a, and b are integers and M is an alkali metal such as sodium, or hydrogen, and the monomer units are in random order, (x + y):z is from about 5:1 to 1000:1, and y can be any value ranging from zero up to the maximum value of x, and b can be zero, and R1 = H or CH3, R2 = COOM, OCH3, SO3M, O-CO-CH3, CO-NH2, R4 is ethyleneoxy and R5 is alkyleneoxy, preferably propyleneoxy or butyleneoxy, with the provision that, if b is different from 0, the values of a and b in the sidechain are such that the combined weights of R4 and R5 are such that the monomer has a solubility of at least about 500 grams/liter in water. Water makes up the remainder of the laundry detergent formulation.
