Abstract

The present invention relates to a method of shaping a fibrous material and treatment compositions therefor. The method comprises providing a treatment composition comprising an active agent and a photocatalyst, applying the treatment composition to the fibrous material to form a treated fibrous material, mechanically shaping the treated fibrous material, and exposing the treated fibrous material to electromagnetic radiation. The treatment composition comprises an active agent, wherein the active agent comprises a monoamine, diamine, or polyamine; and a photocatalyst.

First claim

What is claimed is:

1 . A method for shaping fibrous material comprising:
(a) providing a treatment composition, wherein the treatment composition comprises:
(i) an active agent comprising a monoamine, diamine, or polyamine; and
(ii) a photocatalyst;
(b) applying the treatment composition to a fibrous material to form a treated fibrous material; (c) mechanically shaping the treated fibrous material; and (d) exposing the treated fibrous material to electromagnetic radiation.

2 . The method of claim 1 , wherein said active agent has a molecular weight below about 1000 g/mol.

3 . The method of claim 1 , wherein the electromagnetic radiation has a wavelength of from about 300 nm to about 750 nm.

4 . The method of claim 1 , wherein the photocatalyst is a photoacid.

5 . The method of claim 4 , wherein the photoacid is a hydroxyl-substituted aromatic compound.

6 . The method of claim 1 , wherein the step of mechanically shaping the fibrous material comprises using an implement.

7 . The method of claim 6 , wherein the implement comprises a light source.

8 . The method of claim 7 , wherein the light source is selected from the group consisting of incandescent light, fluorescent light, LED light, laser light, solar light, and combinations thereof.

9 . The method of claim 1 , wherein the treatment composition has not been exposed to electromagnetic radiation having a wavelength of less than 750 nm for a period of at least 1 second before the step of applying the treatment composition to the fibrous material.

10 . The method of claim 1 , wherein the photocatalyst is selected from the group consisting of: 8-hydroxyquinoline, 8-hydroxyquinoline sulfate, 8-quinolinol-1-oxide, 5-hydroxyquinoline, 6-hydroxyquinoline, 7-hydroxyquinoline, 5-iodo-7-sulfo-8-hydroxyquinoline, 5-fluoro-8-hydroxyquinoline, 5-fluoro-7-chloro-8-hydroxyquinoline, 5-fluoro-7-bromo-8-hydroxyquinoline, 5-fluoro-7-iodo-8-hydroxyquinoline, 7-fluoro-8-hydroxyquinoline, 5-chloro-8-hydroxyquinoline, 5,7-dichloro-8-hydroxyquinoline, 5-chloro-7-brono-8-hydroxyquinoline, 5-chloro-7-iodo-8-hydroxyquinoline, 7-chloro-8-hydroxyquinoline, 5-bromo-8-hydroxyquinoline, 5-bromo-7-chloro-8-hydroxyquinoline, 5,7-dibromo-8-hydroxyquinoline, 5-bromo-7-iodo-8-hydroxyquinoline, 7-bromo-8-hydroxyquinoline, 5-iodo-8-hydroxyquinoline, 5-iodo-7-chloro-8-hydroxyquinoline, 5,7-diiodo-8-hydroxyquinoline, 7-iodo-8-hydroxyquinoline, 5-sulfonic acid-8-hydroxyquinoline, 7-sulfonic acid-8-hydroxyquinoline, 5-sulfonic acid-7-iodo-8-hydroxyquinoline, 5-thiocyano-8-hydroxyquinoline, 5-chloro-8-hydroxyquinoline, 5-bromo-8-hydroxyquinoline, 5,7-dibromo-8-hydroxyquinoline, 5-iodo-8-hydroxyquinoline, 5,7-diiodo-8-hydroxyquinoline, 7-azaindole, 7-cyano-2-naphthol, 8-cyano-2-naphthol, 5-cyano-2-naphthol, 1-hydroxy-3,6,8-pyrenetrisulfonic acid, trans-3-hydroxystilbene, 2-hydroxymethylphenol, Pelargonidin, and mixtures thereof.

11 . The method of claim 1 , wherein the fibrous material is selected from the group consisting of keratin fibers, cellulosic fibers, synthetic fibers, and combinations thereof.

12 . The method of claim 1 , wherein the fibrous material is keratin fibers.

13 . The method of claim 1 , wherein the fibrous material is a woven or nonwoven fabric.

14 . The method of claim 1 , wherein the method further comprises elevating the temperature of the treated fibrous material to a temperature of from about 40° C. to about 150° C.

15 . The method of claim 6 , wherein the implement further comprises a heat source.

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

17 . The method of claim 1 , wherein the treatment composition comprises from about 0.1% to about 99.99%, by weight of the treatment composition, of the active agent.

18 . The method of claim 1 , wherein the treatment composition further comprises a carrier.

19 . The method of claim 18 , wherein the carrier is water.

20 . The method of claim 1 , wherein the treatment composition is a solid, and wherein the method further comprises the step of dissolving the treatment composition in a carrier.

21 . The method of claim 1 , wherein the active agent is a diamine or polyamine.

22 . The method of claim 1 , wherein the active agent is a primary amine, a secondary amine, or mixtures thereof.

23 . The method of claim 1 , wherein said active agent is a tertiary amine having a molecular weight below about 300 g/mol.

24 . The method of claim 1 , wherein the active agent is a diamine selected from the group consisting of 1,7-diaminoheptane, 1,4-diaminobutane, and mixtures thereof.

25 . The method of claim 1 , wherein the treatment composition is packaged in an opaque package.

26 . A treatment composition for shaping fibrous material comprising:
