Boosting the cleaning performance of laundry detergents by polymer of styrene/methyl methacrylate/methyl polyethylene glycol

1. A method of washing a textile comprising contacting the textile with a cleaning composition comprising a copolymer comprising styrene, methyl methacrylate and methyl polyethylene glycol.

2. The method of claim 1 wherein the textile is a cotton textile.

3. The method of claim 1 wherein the polymer comprises from 5 to 40 mol %, styrene, from 20 to 40 mol % methyl methacrylate and from 25 to 65 mol % methyl polyethylene glycol.

4. The method of claim 1 wherein the polymer is a block copolymer.

5. The method of claim 1 further comprising a soil-release-enabling polyester of a dicarboxylic acid and diol, a polymeric diol or a mixture thereof.

6. The method of claim 1 wherein the average molar weight of the polymer is less than 10,000 D.

7. The method of claim 6 wherein the average molecular weight is from 3000 D to 8000 D.

8. A washing agent containing a soil-release-enabling copolymer comprising styrene, methyl methacrylate and methyl polyethylene glycol.

9. The washing agent of claim 8 wherein the amount of the soil-release-enabling polymer is from 0.1 wt % to 2 wt %.

10. The washing agent of claim 9 wherein the amount of the soil-release-enabling polymer is from 0.4 wt % to 1 wt %.

11. A method for manufacturing a solid washing agent comprising mixing a particle comprising the soil-release-enabling polymer comprising styrene, methyl methacrylate methyl polyethylene glycol and a solid washing-agent.
