Abstract
Hard surfaces can be treated to improve soil resistance, particularly resistance to oily soils, by applying a composition of a quaternised, polyamine, polypropoxylate, polyethoxylate. The polyamine can be a polyethyleneimme, desirably having a molecular weight of from 10 to 50 kDa. The average length of the polypropylenoxy chains is desirably from 10 to 100 and the polyethylenoxy chains from 5 to 50 (each per NH group in the polyamine), particularly at a molar ratio of PO:EO of about 3:1. The degree of quaternization of the nitrogen atoms in the polyamine is desirably from 70 to 100%. The polymer will usually be used in solution in water or an aqueous formulation, which may include detergent and other detergent formulation components.
