Abstract

A method for shaping keratin fibres including providing a crosslinking composition, wherein the crosslinking composition includes ethylene carbonate, arabinose, a photocatalyst being a hydroxy-substituted aromatic compound, and a cosmetically acceptable carrier; applying the crosslinking composition to keratin fibres; and mechanically shaping the keratin fibres with an appliance at a temperature of from 80° C. to 180° C. while exposing the crosslinking composition to electromagnetic radiation having a wavelength of from 300 nm to 750 nm.

First claim

What is claimed is:

1 . A method for shaping keratin fibres comprising:
(a) providing a crosslinking composition, wherein the crosslinking composition comprises:
ethylene carbonate;
arabinose;
a photocatalyst being a hydroxy-substituted aromatic compound; and
a cosmetically acceptable carrier;
wherein the crosslinking composition has not been exposed to electromagnetic radiation having a wavelength of 750 nm or less for 30 min or more; (b) applying the crosslinking composition to keratin fibres; and (c) mechanically shaping the keratin fibres with an appliance at a temperature of from 80° C. to 180° C. while exposing the crosslinking composition to electromagnetic radiation having a wavelength of from 300 nm to 750 nm.

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

3 . The method according to claim 1 , wherein the appliance comprises light-emitting diodes.

4 . The method according to claim 1 , wherein the photocatalyst can be activated to a photo-excited state by excitation with incident radiation with a wavelength from 300 nm to 750 nm and wherein the appliance emits radiation with a wavelength from 300 nm to 750 nm.

5 . The method according to claim 1 , wherein the hydroxy-substituted aromatic compound is 8-hydroxyquinoline.

6 . The method according to claim 1 , wherein the composition is substantially free of formaldehyde, derivatives of formaldehyde, formalin, and any compound that produces formaldehyde upon heating.

7 . The method according to claim 1 , wherein the method does not comprise a rinsing step.

8 . The method according to claim 1 , wherein the crosslinking composition comprises from about 0.1% to about 20% arabinose, by weight of the crosslinking composition.

9 . The method according to claim 1 , wherein the crosslinking composition comprises from about 2% to about 13% arabinose, by weight of the crosslinking composition.

10 . The method according to claim 1 , wherein the crosslinking composition comprises from about 4% to about 6% arabinose, by weight of the crosslinking composition.

11 . The method according to claim 1 , wherein the crosslinking composition comprises from about 9% to about 11% arabinose, by weight of the crosslinking composition.

12 . The method according to claim 1 , wherein the crosslinking composition comprises from about 2% to about 18% ethylene carbonate, by weight of the crosslinking composition.

13 . The method according to claim 1 , wherein the crosslinking composition comprises from about 4% to about 6% ethylene carbonate, by weight of the crosslinking composition.

14 . The method according to claim 1 , wherein the crosslinking composition comprises from about 14% to about 16% ethylene carbonate, by weight of the crosslinking composition.

15 . The method according to claim 1 , wherein arabinose and ethylene carbonate have a weight ratio of from about 7:4 to about 9:4.

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

17 . The method according to claim 1 , wherein arabinose and ethylene carbonate have a weight ratio of from about 3:12 to about 5:12.

18 . The method according to claim 1 , wherein arabinose and ethylene carbonate have a weight ratio of about 1:3.

19 . The method according to claim 1 , wherein the crosslinking composition further comprises 1,2-bis(2-maleimidoethoxy)ethane.

20 . A crosslinking composition for shaping keratin fibres comprising:
(a) ethylene carbonate; (b) arabinose; (c) a photocatalyst being a hydroxy-substituted aromatic compound; and (d) a cosmetically acceptable carrier; wherein the crosslinking composition has not been exposed to electromagnetic radiation having a wavelength of 750 nm or less for 30 min or more; and wherein arabinose and ethylene carbonate have a weight ratio of about 2:1 or about 1:3 arabinose:ethylene carbonate.
