Abstract
A cleaner composition which comprises at least one surfactant, at least one builder and at least one nitrogen-containing polymer is described. The nitrogen-containing polymer is, for example, an alkoxylated polyvinylamine, an alkoxylated, acylated or alkylated polyaminoamide or a polyurethane-urea with tertiary amino groups. The nitrogen-containing polymers facilitate soil release.

A cleaner composition comprising
- A) at least one surfactant,
- B) at least one builder and
- C) at least one nitrogen-containing polymer with repeat units of the formula III,
- wherein
- R2 is a chemical bond or C1-C20-alkanediyl which is optionally interrupted by a double bond and/or an imino group and/or is optionally, completely or partially, a constituent of one or more saturated or unsaturated carbocyclic 5- to 8-membered rings, where the alkanediyl may carry one or more hydroxyl groups and/or amino groups,
- R3 is C2-C8-alkanediyl or is
- —CH2—CHR4O—CH2—CHR4q
- X is O, NH or C1-C6-alkylamino,
- Z3 is C1-C6-alkyl, phenyl or phenyl-C1-C4-alkyl, if k=0, together with N—R3—X can form a 5- to 7-membered saturated heterocyclic ring having 2 nitrogen atoms or, if k=1, the two radicals Z3 can together with N—CH2—CH2—N form a 5- to 7-membered saturated heterocyclic ring having 2 nitrogen atoms,
- R4 is hydrogen or C1-C10-alkyl,
- q is a number from 1 to 20,
- k is 0 or 1;
- or reaction products thereof with neutralizing agents or quaternizing agents.
