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