Abstract

The invention relates to liquid compositions for use with hair removal devices comprising a methathesized unsaturated polyol ester for improved lubrication.

Claims

1. A composition dispensing hair removal device, said device comprising a composition comprising from 10% to 20% by weight of a metathesized unsaturated polyol ester which is derived from canola oil, the metathesized unsaturated polyol ester having the following properties:

(i) a weight average molecular weight of from 5,000 Daltons to 50,000 Daltons;

(ii) a free hydrocarbon content, based on total weight of said metathesized unsaturated polyol ester, of from 0.5% to 4%; and

(iii) an iodine value of from 30 to 200.

2. The device according to claim 1, wherein said metathesized unsaturated polyol ester has an oligomer index from 0.001 to 1.

3. The device according to claim 1, wherein said free hydrocarbon content is from 0.5% to 3%.

4. The device according to claim 1, wherein the metathesized unsaturated polyol ester is metathesized at least once.

5. The device according to claim 1, wherein said composition further comprises a water soluble polymer.

6. The device according to claim 5, wherein said water soluble polymer is selected from polyethylene oxide, polyvinyl pyrrolidone, polyacrylamide, polyhydroxymethacrylate, polyvinyl imidazoline, polyethylene glycol, polyvinyl alcohol, polyhydroxyethymethacrylate, guars, celluloses, modified celluloses and mixtures thereof.

7. The device according to claim 5, wherein said water soluble polymer is polyethylene oxide having an average molecular weight of between 300,000 and 3 million.

8. The device according to claim 1, wherein said composition further comprises from 0.1% to 8% by weight of a lubricating material of a copolymer of polyethylene oxide and polypropylene oxide.

9. The device according to claim 1, wherein said composition comprises from 0.1% to 5% of a thickening agent and at least 30% by weight of water.

10. The device according to claim 1, wherein said device comprises a handle connected to a hair removal head, wherein said handle comprises a cavity for housing said composition disposed within said handle and an actuator adapted to displace said composition from said cavity to a fluid dispensing member.

11. The device according to claim 10, wherein said fluid dispensing member comprises an elongated contact region forming at least one dispensing orifice.

12. The device according to claim 11, wherein said elongate contact region forms a one way valve.

13. The device according to claim 1, wherein said composition comprises from 10% to 16% by weight of said metathesized unsaturated polyol ester.
