Abstract

The present invention relates to a liquid detergent composition comprising from 0.01 to 40% by weight water, benefit agent-containing microcapsules and an ionic species having at least 2 anionic sites, wherein the ionic strength delivered by the ionic species having at least 2 anionic sites is greater than 0.045 mol/kg.

Claims

1. A liquid detergent composition comprising from about 0.01 to about 40% by weight water, benefit agent-containing microcapsules and an ionic species having at least 2 anionic sites, wherein the ionic species delivers an ionic strength greater than about 0.045 mol/kg.

2. The liquid detergent composition according to claim 1 wherein the composition comprises from about 1 to about 25% by water.

3. The liquid detergent composition according to claim 1 wherein the benefit agent is selected from the group of include perfume raw materials, silicone oils, waxes, hydrocarbons, higher fatty acids, essential oils, lipids, skin coolants, vitamins, sunscreens, antioxidants, glycerine, catalysts, bleach particles, silicon dioxide particles, malodor reducing agents, dyes, brighteners, antibacterial actives, antiperspirant actives, cationic polymers and mixtures thereof.

4. The liquid detergent composition according to claim 1 wherein the benefit agent is a perfume comprising perfume raw materials that are selected such that less than about 15% of the perfume raw materials have Clog P less than about 3 and a boiling point less than about 250°

C. and the remaining perfume raw materials have Clog P of greater than about 3 and/or Clog P less than about 3, but having boiling point of greater than about 250°

C.

5. The liquid detergent composition according to claim 1 wherein the ionic species having at least 2 anionic sites is selected from the group of carboxylic acids, polycarboxylate, phosphate, phosphonate, poly phosphate, polyphosphonate, borate and mixtures thereof.

6. The liquid detergent composition according to claim 5 wherein the ionic species having at least 2 anionic sites is selected from the group of oxydisuccinic acid, aconitic acid, citric acid, tartaric acid, malic acid, maleic acid, fumaric acid, succinic acid, sepacic acid, citaconic acid, adipic acid, itaconic acid, dodecanoic acid and mixtures thereof.

7. The liquid detergent composition according to claim 5 wherein the ionic species having at least 2 anionic sites is selected from the group of acrylic acid homopolymers and copolymers of acrylic acid and maleic acid.

8. The liquid detergent composition according to claim 1 additionally comprising positively charged ion comprising at least 2 cationic sites.
