Abstract
Surface treatment compositions comprising certain cationic polymer(s), anionic surfactant, one or more shielding salts and hydrophobic association disruptor. The surface treatment compositions comprise at least about 6% by weight of cationic polymer, at least about 6% by weight anionic surfactant, and at least about 4% by weight of the shielding salt. The weight ratio of anionic surfactant to cationic polymer is between about 0.5:1 and about 4:1. The composition may also have a weight ratio of shielding salt to cationic polymer of between about 0.3:1 and about 3:1.
