Abstract

A hair removal device is provided comprising an erodable solid moisturizer, the erodable solid moisturizer comprising:

• • a. A modifying surfactant comprising:
    • i. A carbon chain with 12 to 32 carbon atoms;
    • ii. From 1 to 19 ethylene oxide groups;
  • b. At least 50% hydrophobic phase by weight of the erodable solid moisturizer.

Claims

1. A hair removal device comprising an erodable solid moisturizer, the erodable solid moisturizer comprising:

a. a modifying surfactant comprising;

i. a carbon chain with 12 to 32 carbon atoms;

ii. from 1 to 19 ethylene oxide groups;

b. at least 50% hydrophobic phase by weight of the erodable solid moisturizer.

2. The hair removal device of claim 1, wherein the erodable solid moisturizer comprises from 1% to 12% of modifying surfactant by weight of the erodable moisturizer.

3. The hair removal device of claim 1, wherein the erodable solid moisturizer comprises from 3% to 11% of modifying surfactant by weight of the erodable moisturizer.

4. The hair removal device of claim 1, wherein the erodable solid moisturizer comprises from 4% to 10% of modifying surfactant by weight of the erodable moisturizer.

5. The hair removal device of claim 1, wherein the modifying surfactant comprises from 16 to 20 carbon atoms.

6. The hair removal device of claim 1, wherein the modifying surfactant comprises two ethylene oxide groups.

7. The hair removal device of claim 1, wherein the modifying surfactant is saturated.

8. The hair removal device of claim 1, wherein the erodable solid moisturizer has a Chatillon Hardness of 0.50 kg to 3.50 kg.

9. The hair removal device of claim 1, wherein the hydrophobic phase comprises wax.

10. The hair removal device of claim 1, wherein the erodable moisturizer comprises from 2% to 20% wax by weight of the erodable solid moisturizer.

11. The hair removal device of claim 1, wherein the erodable solid moisturizer comprises a water-insoluble structuring polymer.

12. The hair removal device of claim 11, wherein the water-insoluble structuring polymer is soluble in or miscible with the hydrophobic phase at the melting point of the water-insoluble structuring polymer.

13. The hair removal device of claim 11, wherein the erodable solid moisturizer comprises from 2% to 50% water-insoluble structuring polymer by weight of the erodible solid moisturizer.

14. The hair removal device of claim 11, wherein the erodable solid moisturizer comprises from 4% to 12% water-insoluble structuring polymer by weight of the erodible solid moisturizer.

15. The hair removal device of claim 11, wherein the water-insoluble structuring polymer comprises a block copolymer.

16. The hair removal device of claim 1, wherein the erodable solid moisturizer comprises from 60% to 95% hydrophobic phase by weight of the erodable solid moisturizer.

17. The hair removal device of claim 1, wherein the erodable solid moisturizer comprises from 70% to 90% hydrophobic phase by weight of the erodable solid moisturizer.

18. The hair removal device of claim 1, configured as a razor comprising one or more cutting blades.

19. The razor according to claim 18, wherein the erodable solid moisturizer is configured as a strip disposed on one or both sides of the cutting blade(s).

20. A method of removing hair and moisturizing the skin, comprising the step of contacting the skin with a hair removal device according to claim 1.
