Abstract

The invention is directed to a liquid laundry detergent composition comprising at least one detergent ingredient selected from the group consisting of anionic surfactant, zwitterionic surfactant, amphoteric surfactant, and mixtures thereof; a coacervate phase forming cationic polymer; and one or more fabric care ingredients selected from the group consisting of one or more cationic silicone polymers comprising one or more polysiloxane units and one or more nitrogen moieties; one or more amino silicone polymers; one or more nitrogen-free silicone polymers; and mixtures thereof; and a liquid carrier for providing cleaning and fabric care benefits. A process for preparing such compositions, a method for treating substrates, a method for providing certain fabric care benefits and the use of such compositions are also described.

Claims

1. A liquid laundry detergent composition comprising

(a) at least one detergent ingredient selected from the group consisting of anionic surfactants, zwitterionic surfactants, amphoteric surfactants, and mixtures thereof;

(b) a coacervate phase forming cationic polymer selected from guar gums in an amount of from 0.05% to 0.2% by weight of the composition;

(c) one or more fabric care ingredients selected from linear cationic silicone block copolymers according to the formula;

2. A liquid laundry detergent composition according to claim 1, wherein the cationic silicone polymer comprises one or more polysiloxane units and one or more quaternary nitrogen moieties in the backbone of the copolymer.

3. A liquid laundry detergent composition according to claim 1, wherein the cationic silicone polymer comprises at least 2 polysiloxane units and at least 2 quaternary nitrogen moieties in the backbone of the copolymer.

4. A liquid laundry detergent comprising according to claim 1 wherein the one or more enzymes are selected from proteases, amylases, cellulases, mannanase, endoglucanase, lipase and mixtures thereof.
