CLAIMS

1. A hair conditioning composition comprising from 0.001 to 50% by weight of a thermotropic mesogenic material.

2. A hair conditioning composition according to claim 1
comprising a water-insoluble oily conditioning material.

3. A hair conditioning composition according to claim 2 wherein the thermotropic mesogenic material is miscible into an intimate dispersion stable to phase separation with the water-insoluble oily conditioning material.

4. A hair conditioning composition comprising an intimate dispersion stable to phase separation of a thermotropic mesogenic material and an oily water-insoluble
conditioning material .

5. A hair conditioning composition according to claim 4 wherein the thermotropic mesogenic material comprises from 0.01 to 50% by weight of the dispersion stable to phase separation of thermotropic mesogenic material and oily water-insoluble conditioning material.

6. A hair conditioning composition according to any one of claims 4 and 5 wherein the dispersion stable to phase separation additionally comprises a cationic surfactant.

7. A hair conditioning composition according to any one of claims 2 to 6 wherein the water-insoluble oily conditioning material comprises a silicone-based
polymer .

8. A hair conditioning composition according to claim 7 wherein the thermotropic mesogenic material comprises a silicone-based polymeric segment.

9. A method for preparing a hair conditioning composition which is in the form of an Lβ lamellar phase dispersion at 25 °C, comprising a cationic surfactant, a fatty material, a thermotropic mesogenic material and water, wherein the thermotropic mesogenic material is mixed into the composition prior to or during the formation of the Lβ lamellar phase dispersion.

10. A method for preparing a hair conditioning composition comprising the steps of:
a) forming a dispersion stable to phase separation
comprising a thermotropic mesogenic material and an oily water-insoluble conditioning material.

b) blending the dispersion stable to phase separation
with the remaining components of the hair
conditioning composition.

11. A method according to claim 10 wherein the dispersion stable to phase separation of step a) additionally comprises a cationic surfactant.

12. The use of a hair treatment composition according to any preceding claim for the conditioning of hair.

3. A method for the improvement of the hair conditioning characteristics of a water-insoluble conditioning material by the addition of a thermotropic mesogenic material to said water-insoluble conditioning material
