Abstract

The invention relates to a liquid detergent composition comprising at least one anionic surfactant, at least one ethoxylated glycerol compound, at least one organic solvent comprising glycerol, an amount of water not more than 10% by weight in relation to the entirety of the detergent composition, and optionally, a partially or fully neutralized fatty acid. Said composition is suitable for use in unit doses which also comprise a water-soluble capsule for washing clothes. The invention also relates to said unit dose and to methods for producing the composition and the unit dose.

Claims

1. A liquid detergent composition comprising:

a) at least one anionic surfactant,

b) at least one ethoxylated glycerol compound comprising at least one component of formula (II)

2. The liquid detergent composition according to claim 1, wherein component b) comprises at least two different components of formula (II):

one of formula (i), (ii) or (iii), and another of formula (iv), the weight ratio of components [(i)+(ii)+(iii)]/(iv) being between 30.0;

0.3 and 0.5;

3.0.

3. The liquid detergent composition according to claim 1, wherein the sum of m, n and l is comprised between 10 and 100 and the weight ratio of components [(i)+(ii)+(iii)]/(iv) is greater than 50.

4. The liquid detergent composition according to claim 1, additionally comprising:

a) at least one sequestering agent, preferably phosphonate and/or citrate.

5. The composition according to claim 1, additionally comprising:

b) at least one optical brightener.

6. The composition according to claim 1, additionally comprising:

c) at least one or more enzymes.

7. The composition according to claim 1, wherein component a) is selected from alkyl ether sulfates, alkyl ether carboxylic acids and and/or their salts and sulfosuccinates, more preferably alkyl ether sulfates.

8. The composition according to claim 1, wherein the c1:

c2 weight ratio is greater than 1.5.

9. The composition according to claim 8, wherein the c1:

c2 ratio is greater than 2, more preferably greater than 2.4.

10. The composition according to claim 1, wherein solvent c2 is not propylene glycol.

11. A method for preparing the liquid detergent compositions having components as defined in claim 1, which comprises mixing the components a temperature suitable for homogenization thereof, preferably at room temperature.

12. A liquid unit dose comprising a water-soluble capsule having at least one compartment and a liquid housed therein, characterized in that said liquid is a liquid detergent composition according to claim 1.

13. The liquid unit dose according to claim 12, wherein the water-soluble capsule is a polyvinyl alcohol capsule.

14. A method for preparing a liquid unit dose as defined in claim 12, which comprises encapsulating the liquid detergent composition in a water-soluble capsule.

15. A method for cleaning clothes which comprises contacting the clothes with the liquid unit doses defined in claim 12.

16. A method for cleaning clothes which comprises contacting the clothes with the liquid detergent composition according to claim 1.

17. (canceled)
