CLAIMS

1. A cleansing composition capable of enhancing deposition of benefit agent comprising:
i. a functional oil-in-water emulsion comprising
0.1 % to 5 % by weight benefit agent
solubilised/dispersed in an oil and emulsified in water using a cationic emulsifier having an HLB
greater than 8 such that the ratio of oil: cationic emulsifier is in the range 20:1 to 1:1;
ii. a detergent active composition comprising 5 % to
80 % detergent active; and
iii. a cationic polymer.

2. A composition according to claim 1 wherein the benefit agent is selected from sunscreen, perfume or antibacterial agent.

3. A composition according to claim 1 or claim 2 wherein the cationic emulsifier has an HLB in the range of 13 to 18.

4. A composition according to claim 3 wherein the cationic emulsifier is chosen from the group of quaternary ammonium surfactant compounds.

5. A composition according to any one of claims 1 to 4 wherein the ratio of the oil: cationic emulsifier is in the range of 10:1 to 1:1.

6. A composition according to any one of claims 1 to 5
wherein the cationic polymer is selected from
poly (diallyl dimethyl ammonium chloride), poly (dimethyl amino ethyl acrylate) -quaternized {DMAEA quat}, poly
(dimethyl amino ethyl ethacrylate) -quaternized {DMAEM quat}, or poly (methacrylamido propyl trimethyl ammonium chloride) {MAPTAC}, or mixtures thereof.

7. A composition according to any one of claims 1 to 6 wherein the cationic polymer is present in an amount of 0.75 % to 4.0 %.

8. A composition according to any one of claims 1 to 7 wherein the cationic polymer has a molecular weight in the range of 40 kg/mole to 5000 kg/mole.

9. A composition according to claim 8 wherein the cationic polymer has a molecular weight in the range of 200 kg/mole to 500 kg/mole.

10. A composition according to any one of claims 1 to 9 wherein the cationic polymer has a charge density greater than lmEq/g.

11. A composition according to claim 10 wherein the cationic polymer has a charge density in the range of 5 to 6 mEq/g.

12. A composition according to any of claims 1 to 11 wherein the oil is selected from isopropyl myristate, isopropyl palmitate, silicone oil, or structured mineral oil, or mixtures thereof.

13. A composition according to any of claims 1 to 12 wherein the composition additionally comprises one or more of antioxidants, thickeners, polymers, fragrance,
humectants, pH adjusters, preservatives, or essential oils.

14. A process for the preparation of a cleansing composition for enhanced delivery of benefit agents comprising the steps of:
(i) dispersing/dissolving the benefit agent in an oil by mixing;
(ii) preparing a functional oil-in-water emulsion by
mixing the product of step (i) in water along with a cationic emulsifier;
(iii) mixing the functional oil-in-water emulsion with
other ingredients to prepare a composition
comprising the functional oil-in-water emulsion, a detergent active and a cationic polymer.

15. A process for the preparation of a cleansing composition according to claim 14 wherein the cationic polymer is mixed with the detergent active before it is mixed with the functional oil-in-water emulsion.
