Abstract

A method for shaping keratin fibers including providing a crosslinking composition, wherein the crosslinking composition includes ethylene carbonate, arabinose, and a cosmetically acceptable carrier; applying the crosslinking composition to keratin fibers; and mechanically shaping the keratin fibers with an appliance at a temperature of from about 50° C. to about 250° C.

Claims (37)

1. A method for shaping keratin fibres comprising:

(a) providing a crosslinking composition, wherein the crosslinking composition comprises:

from about 9% to about 11% arabinose;

from about 4% to about 6% ethylene carbonate; and

a cosmetically acceptable carrier;

(b) applying the crosslinking composition to keratin fibres; and

(c) mechanically shaping the keratin fibres with an appliance at a temperature of from about 50° C. to about 250° C.;

wherein the ratio of arabinose to ethylene carbonate is about from 7:4 to about 9:4.

2. The method of claim 1 , wherein the mechanical shaping of keratin fibres is straightening keratin fibres or curling keratin fibres.

3. The method of claim 1 , wherein the crosslinking composition comprises about 10% arabinose, by weight of the crosslinking composition.

4. The method of claim 1 , wherein the crosslinking composition comprises about 5% ethylene carbonate, by weight of the crosslinking composition.

5. The method of claim 1 , wherein arabinose and ethylene carbonate have a weight ratio of about 2:1.

6. The method of claim 1 , wherein the crosslinking composition comprises a conditioning agent being the reaction product of an aminosilane and a polysiloxane.

7. The method of claim 1 , wherein the crosslinking composition is substantially free of the group consisting of formaldehyde, derivatives of formaldehyde, formalin, and any compound that produces formaldehyde upon heating.

8. The method of claim 1 , wherein the method does not comprise a rinsing step.

9. The method of claim 1 , wherein the crosslinking composition further comprises 1,2-bis(2-maleimidoethoxy)ethane.

10. A method for shaping keratin fibres comprising:

a. providing a crosslinking composition, wherein the crosslinking composition comprises:

from about 1.5% to about 3.5% arabinose;

from about 14% to about 16% ethylene carbonate; and

a cosmetically acceptable carrier;

b. applying the crosslinking composition to keratin fibres; and

c. mechanically shaping the keratin fibres with an appliance at a temperature of from about 50° C. to about 250° C.

11. The method of claim 10 , wherein the crosslinking composition comprises about 2.5% arabinose, by weight of the crosslinking composition.

12. The method of claim 10 , wherein the crosslinking composition comprises about 15% ethylene carbonate, by weight of the crosslinking composition.

13. The method of claim 10 , wherein arabinose and ethylene carbonate have a weight ratio of about 1:6.

14. A method for shaping keratin fibres comprising:

a. providing a crosslinking composition, wherein the crosslinking composition comprises:

from about 4% to about 6% arabinose;

from about 14% to about 16% ethylene carbonate; and

a cosmetically acceptable carrier;

b. applying the crosslinking composition to keratin fibres; and

c. mechanically shaping the keratin fibres with an appliance at a temperature of from about 50° C. to about 250° C.;

wherein the ratio of arabinose to ethylene carbonate is from about 3:12 to about 5:12.

15. The method of claim 14 , wherein the crosslinking composition comprises about 5% arabinose, by weight of the crosslinking composition.

16. The method of claim 14 , wherein the crosslinking composition comprises about 15% ethylene carbonate, by weight of the crosslinking composition.

17. The method of claim 14 , wherein arabinose and ethylene carbonate have a weight ratio of about 1:3.
