Patent ID: 8846599

Claim:
A detergent or cleaner for textiles comprising: 0.1 to 99% by weight of at least one surfactant selected from the group consisting of an anionic surfactant, a nonionic surfactant, an amphoteric surfactant and a cationic surfactant; and a mixture comprising the branched polyester with sulfonate groups obtained by a process comprising: reacting an α,β-olefinically unsaturated dicarboxylic acid (A 2 ), a tri- or higher-functional alcohol (By), optionally a difunctional alcohol (B 2 ) or difunctional carboxylic acid (C 2 ) without α,β-olefinically unsaturated bonds, and optionally a fatty acid or fatty alcohol, to obtain an intermediate branched polyester; and subsequently reacting the intermediate branched polyester with hydrogen sulfite, wherein a molar amount of hydrogen sulfite is at most 95 mol %, based on an amount of the α,β-olefinically unsaturated dicarboxylic acid (A 2 ).
