Abstract

The present invention relates to washing or cleaning agents having improved foaming characteristics under high soil loading, containing at least one anionic surfactant and at least one alkylamidopropyl betaine of formula (R1)C(═O)NH(CH2)3N+(R2)(R3)CH2COO−, where R1 is an alkyl radical having 7 to 9 carbon atoms and R2 and R3 are identical or different alkyl radicals having 1 to 3 carbon atoms, wherein the weight ratio of the alkylamidopropyl betaine defined herein/total amount of anionic surfactant in the washing or cleaning agent is from 0.003 to 0.12, wherein the weight ratio of the total amount of alkylamidopropyl betaine as defined herein/total amount of alkylamidopropyl betaine in the washing or cleaning agent is 0.25 to 1.0, to washing or cleaning methods in which washing or cleaning agents of this kind are used.

First claim

What is claimed is:

1. A washing or cleaning agent comprising:
(i) 15% by weight to 20% by weight at least one linear alkylbenzene sulfonate surfactant, based on the total weight of the washing or cleaning agent and
(ii) C 8/10 alkylamidopropyl betaine;

wherein the weight ratio of the alkylamidopropyl betaine according to (ii)/total amount of linear alkylbenzene sulfonate surfactant in the washing or cleaning agent is from 0.036 to 0.087, wherein the weight ratio of the total amount of alkylamidopropyl betaine according to (ii)/total amount of alkylamidopropyl betaine in the washing or cleaning agent is 0.25 to 1.0.

2. The washing or cleaning agent according to claim 1 , characterized in that the at least one first linear alkylbenzene sulfonate surfactant is a linear C 6-19 alkylbenzene sulfonate.

3. The washing or cleaning agent according to claim 1 , characterized in that the washing or cleaning agent further contains at least one constituent selected from the group consisting of enzymes, bleaching agents, complexing agents, builders, electrolytes, non-aqueous solvents, pH adjusting agents, perfumes, perfume carriers, fluorescing agents, dyes, speckles, hydrotropes, silicone oils, anti-redeposition agents, graying inhibitors, shrinkage preventers, anti-crease agents, color transfer inhibitors, antimicrobial active substances, germicides, fungicides, antioxidants, preservatives, corrosion inhibitors, antistatic agents, bittering agents, ironing adjuvants, proofing and impregnating agents, swelling and anti-slip agents, softening components and UV absorbers.

4. The washing or cleaning agent according to claim 1 , characterized in that the washing or cleaning agent is an agent in the form of a powder or granules or is a solid shaped article.

5. A washing or cleaning method, comprising the method steps:
(i) providing a washing or cleaning solution including a washing or cleaning agent according to claim 1 , wherein the washing or cleaning solution includes soil;
(ii) bringing a soiled fabric, into contact with the washing or cleaning solution according to (i).

6. The washing or cleaning method according to claim 5 , characterized in that the method is a washing method, wherein
(i) the washing method is carried out in a washing machine having a static liquor tank and a stirring or circulating device arranged on the bottom or on the side of the liquor tank; and/or
(ii) the washing or cleaning solution is used for multiple wash loads.
