Claims
- 1. A laundry detergent composition comprising 0.01 to 20% of a hydrophilic copolymer by weight of the total surfactant in the laundry detergent composition wherein further, said hydrophilic copolymer comprises an unsaturated hydrophilic monomer and a hydrophilic oxyalkylated monomer having the following structure: ##STR5## where R3, Q, and M comprise the hydrophilic oxyalkylated monomer sidechain; and M is an alkali metal or hydrogen; Q is an oxyethylene or a mixture of oxyethylene with C3 or C4 oxyalkylene; a is an integer such that said sidechain has a solubility of at least 500 g/l in water; (x+y):z is from about 5:1 to 1000:1, and y is from zero up to the value of x, and further x cannot be zero; ##STR6##
- 2. The laundry detergent composition of claim 1, wherein said copolymer has a molecular weight within the range of about 1000 to 100,000.
- 3. The laundry detergent composition of claim 2, wherein said copolymer has a molecular weight within the range of about 1000 to 20,000.
- 4. The laundry detergent composition of claim 1, wherein R.sub.1 =H, R.sub.2 =COOM, wherein M is sodium, R.sub.3 =CH.sub.2 --O, y=0, Q is oxyethylene or a mixture of oxyethylene with C3 or C4 oxyalkylene with the proviso that said sidechain has a solubility of at least 500 g/l in water.
- 5. A composition according to claim 4, wherein said hydrophilic oxyalkylated monomer has a molecular weight of 700-5000.
- 6. A method of preventing soil redeposition, comprising adding 0.01 to 20% of a hydrophilic copolymer by weight of the total surfactant in the laundry detergent composition wherein further, said hydrophilic copolymer comprises an unsaturated hydrophilic monomer and a hydrophilic oxyalkylated monomer having the following structure: ##STR7## where x, y, z and a are integers; R3, Q, and M comprise the hydrophilic oxyalkylated monomer sidechain and Q is oxyethylene or a mixture of oxyethylene with C3 or C4 oxyalkylene with the proviso that said sidechain has a solubility of at least 500 g/l in water; M is an alkali metal such as sodium or hydrogen, (x+y):z is from about 5:1 to 1000:1, and y is from zero up to the value of x, and further x cannot be zero; ##STR8##
- 7. The method of claim 6, wherein said copolymer has a molecular weight within the range of about 1000 to 100,000.
- 8. The method of claim 7, wherein said copolymer has a molecular weight within the range of about 1000 to 20,000.
- 9. The method of claim 6, wherein R.sub.1 =H, R.sub.2 =COOM, wherein M is sodium, R.sub.3 =CH.sub.2 --O, y=0, Q is oxyethylene or a mixture of oxyethylene with C3 or C4 oxyalkylene with the proviso that said sidechain has a solubility of at least 500 g/l in water.
