Abstract

A liquid laundry composition comprising: (i) one or more anionic surfactants; and (ii) a non-ionic ethoxylated C10 Guerbet alcohol surfactant with a degree of ethoxylation in the range of 1 to 10; wherein the total amount of anionic surfactant in the composition is in the range of 3 to 18 wt % of the total composition and the weight ratio of the total amount of anionic surfactant to the non-ionic ethoxylated C10 Guerbet alcohol surfactant is in the range of 6:1 to 60:1. Use of a liquid laundry detergent composition including said non-ionic ethoxylated C10 Guerbet alcohol surfactant for laundering textiles wherein effective foam is maintained during a main wash step and an easy rinse of the textiles is provided during a rinse step.

Dependent claims

A liquid laundry composition comprising:

surfactants consisting of:
(i) sodium lauryl ether sulphate (SLES) and sodium dodecyl benzene sulphonate (NaLAS);
wherein the total amount of anionic surfactant in the composition is 3 to 18 wt % of the total composition;
wherein a weight ratio of the sodium dodecyl benzene sulphonate to the sodium lauryl ether sulphate is 5:2 to 7:2;
and
(ii) a non-ionic ethoxylated C10 Guerbet alcohol surfactant with a degree of ethoxylation of 1 to 4;
wherein the weight ratio of the total amount of anionic surfactant to the non-ionic ethoxylated C10 Guerbet alcohol surfactant is 6:1 to 60:1 so as to result in the maintenance of an effective amount of foam;
and
water.
