Abstract

Use of cationically modified, particulate, hydrophobic polymers, the surface of which has been cationically modified by coating with polyvalent metal ions and/or cationic surfactants, the particle size of which is 10 nm to 100 μm, as additive to rinse compositions, care compositions, detergents and cleaners, and also rinse compositions, care compositions, detergents and cleaners which comprise the cationically modified, particulate, hydrophobic polymers.
