Definitions
- the present invention relates to the use of certain polymers containing nitrogen atoms for enhancing the primary detergency of laundry detergents or cleaners when washing textiles or cleaning hard surfaces against, in particular, oil and / or greasy soils, and detergents and cleaners containing such polymers.
- Detergents contain in addition to the indispensable for the washing process ingredients such as surfactants and builder materials usually further ingredients that can be summarized by the term washing aids and include as different drug groups such as foam regulators, grayness inhibitors, bleach, bleach activators and dye transfer inhibitors.
- Such excipients also include substances whose presence enhances the detergency of surfactants, without them usually having to exhibit a pronounced surfactant behavior itself. The same applies mutatis mutandis to cleaners for hard surfaces.
- Such substances are often referred to as a detergency booster or because of their particularly pronounced effect against oil or fat-based stains as a "fat booster".
- copolymers of N-vinylcaprolactam and N-vinylacetamide have particularly good primary washing strength-enhancing properties.
- the invention relates to the use of polymers obtainable by copolymerization of N-vinylcaprolactam with N-vinylacetamide, for enhancing the Primärwaschkraft of detergents or cleaning agents when washing textiles or when cleaning hard surfaces against particular oil and / or greasy stains.
- the polymers essential to the invention are obtainable by free-radical copolymerization of N-vinylcaprolactam with N-vinylacetamide, which can be carried out as a blockwise or preferably random copolymerization. They have no other units except units originating from the two monomers mentioned, it being possible for units derived from the free radical initiator to be present at the polymer ends as a result of the preparation.
- the units N-vinylcaprolactam and N-vinylacetamide are preferably present in molar ratios in the range from 1:99 to 99: 1, in particular from 25:75 to 50:50.

- Another object of the invention is therefore the use of a combination of polymers of the units N-vinylcaprolactam and N-vinylacetamide and alkylbenzenesulfonate with linear Cz -is-alkyl groups, in particular linear C9-13-alkyl groups, to enhance the Primärwaschkraft of detergents or cleaning agents when washing textiles or when cleaning hard surfaces against especially oil and / or greasy stains.
- the weight ratio of linear alkylbenzenesulfonate to polymer essential to the invention is preferably in the range from 20: 1 to 1: 1, in particular from 8: 1 to 2: 1.

- significant amounts of surfactants can be saved while retaining the ability to remove grease.
