Abstract

Aqueous liquid detergent dispersions are claimed which essentially comprise 5% by weight to 35% by weight of anionic surfactant 10% by weight to 50% by weight of builders, 0% by weight to 10% by weight of electrolytes and 0.1% by weight to 10% by weight of quaternary alkylhydroxyethylammonium salt, where the % by weight ratio of anionic surfactant to quaternary alkylhydroxyethylammonium salt is 50:1 to 2:1.

Claims (16)

1. An aqueous liquid detergent dispersion which consists of:

5% by weight to 35% by weight of anionic surfactant consisting of a sec-alkanesulfonate

10% by weight to 50% by weight of builders,

0% by weight to 10% by weight of electrolytes,

0.1% by weight to 10% by weight of quaternary alkylhydroxyethylammonium salt, selected from the group of C 12 -C 14 -alkyldimethylhydroxyethylammonium chloride, C 12 -C 14 -alkyldlmethylhydroxyethyammonium methosulfate, and mixtures thereof, and

customary auxiliaries and additives selected from the group consisting of bleach activators, bleach catalysts, optical brighteners, graying inhibitors, color transfer inhibitors, solubility promoters, hydrotropes, thickeners, preservatives, fragrances and dyes, pearlizing agents, foam inhibitors, sequesterants, corrosion inhibitors, antioxidants, and mixtures thereof,

where the % by weight ratio of anionic surfactant to quaternary alkylhydroxyethylammonium salt is 50:1 to 2:1.

2. The aqueous liquid detergent dispersion as claimed in claim 1 , wherein the anionic surfactant consists of a sodium C 13 -C 17 -sec-alkanesulfonate.

3. The aqueous liquid detergent dispersion as claimed in claim 1 , which consists of 5 to 25% by weight of anionic surfactant.

4. The aqueous liquid detergent dispersion as claimed in claim 1 , which consists of 5 to 20% by weight of anionic surfactant.

5. The aqueous liquid detergent dispersion as claimed in claim 1 , which consists of 10 to 40% by weight of builders.

6. The aqueous liquid detergent dispersion as claimed in claim 1 , which consists of 10 to 30% by weight of builders.

7. The aqueous liquid detergent dispersion as claimed in claim 1 , which consists of 0 to 7% by weight of electrolytes.

8. The aqueous liquid detergent dispersion as claimed in claim 1 , which consists of 0 to 4% by weight of electrolytes.

9. The aqueous liquid detergent dispersion as claimed in claim 1 , wherein a weight ratio of anionic surfactant to quaternary alkylhydroxyethylammonium salt is 30:1 to 2:1.

10. The aqueous liquid detergent dispersion as claimed in claim 1 , wherein a weight ratio of anionic surfactant quaternary alkylhydroxyethylammonium salt is 15:1 to 2:1.
