Abstract

Keratin-fiber protectant, curl minimizing composition are disclosed comprising an effective keratin-protective amount of a physiologically tolerable curl minimizing agent selected from the group consisting of a polyfunctional aldehyde, an activated olefin-containing compound, and a polycarboxylic acid. Also disclosed are methods and kits for using the compositions for minimizing the natural curl configuration of human hair in particular.

Claims

1. A keratin-fiber protectant, curl minimizing composition comprising an effective keratin-protective amount of a physiologically tolerable curl minimizing agent selected from the group consisting of a polyfunctional aldehyde, an activated olefin-containing compound, and a polycarboxylic acid.

2. The protectant, curl minimizing composition of claim 1 wherein the polyfunctional aldehyde is a dialdehyde selected from the group consisting of glutaraldehyde, and glyoxal.

3. The protectant, curl minimizing composition of claim 1 wherein the activated olefin-containing compound is selected from the group consisting of maleic acid and esters thereof, maleimides and N-substituted derivatives thereof, maleamic acid and N-substituted derivatives thereof, and maleic anhydride

4. The protectant, curl minimizing composition of claim 1 wherein the activated olefin-containing compound comprises at least one poly(C₂-C₄) alkylene glycol ester of maleic acid.

5. The protectant, curl minimizing composition of claim 1 wherein the activated olefin-containing compound comprises poly(oxy-1,2-ethanediyl)-alpha-hydro-omega-hydroxy, (2Z)-2-butenedioate.

6. The protectant, curl minimizing composition of claim 1 wherein the polycarboxylic acid selected from the group consisting of 1,2,3,4-butanetetracarboxylic acid (BTCA), 1,2,3,4-cyclopentanetetracarboxylic (CPTA), citric acid, and polyacrylic acid.

7. The protectant, curl minimizing composition of claim 1 wherein the composition has a pH in the range of about 2 to about 11.

8. The protectant curl minimizing composition of claim 7 wherein the composition includes a Lewis acid catalyst.

9. The protectant curl minimizing composition of claim 1 wherein the composition includes a polyvinyl alcohol.

10. The protectant curl minimizing composition of claim 1 wherein the composition includes a cyclodextrin.

11. A method of minimizing the natural curl in proteinaceous keratin, the method comprising contacting the keratin with a protectant, curl minimizing composition of claim 1 for a time period sufficient to minimize the curl configuration, said contact being optionally heat-assisted.

12. The method of claim 11 further comprising washing the keratin fibers after contact with the protectant curl minimizing composition.

16. A method of minimizing the natural curl in proteinaceous keratin, the method comprising the steps of:

(a) contacting the keratin with a keratin-reducing composition for a time period sufficient to produce reduced keratin;

(b) removing the keratin-reducing composition from the reduced keratin by washing with water;

(c) contacting the washed reduced keratin with a protectant, curl minimizing composition of claim 1 for a time period sufficient to minimize the curl configuration, said contact optionally being heat-assisted;

(d) contacting the curl-minimized, reduced keratin with an oxidizing composition for a time period sufficient to oxidize the reduced keratin; and

(e) removing the oxidizing composition from the keratin by washing with water to provide curl-minimized keratin.

18. The method of claim 16 wherein after step (e), the curl-minimized keratin is contacted with a subsequent curl minimizing composition that is the same or different than said curl minimizing composition of step (c) and substantially dried, said drying being optionally heat-assisted.

19. The method of claim 18 wherein the subsequent curl-minimizing composition is a thermal protectant composition.

21. The method of claim 19 wherein the substantially dry keratin is pressed with a flat iron heated to a temperature of about 160°

C.

22. The method of claim 16 performed on human hair keratin.

23. An article of manufacture for use in minimizing the natural curl in human hair comprising a kit containing at least one keratin-fiber protectant, curl minimizing composition of claim 1 in packaged form, and optionally further including at least one of the following:

a preconditioning composition;

a thermal protectant composition, each of the foregoing compositions being in separately packaged form;

instructional indicia for performing a curl minimizing process; and

implements for performing one or more steps in the process.

25. The article of manufacture of claim 23 wherein any one of the compositions includes a keratin-protective, curl minimizing agent.

26. The article of manufacture of claim 23 including at least one of the following:

a thiol salt-containing, keratin-reducing composition,

an oxidative composition,

each of the foregoing compositions being in separately packaged form.

27. The method of claim 11 including the step of characterizing the curl minimization by performing Fourier transform analysis of the orientation of the fiber alignment and numerically quantifying the deviation therefrom.

13. (canceled)

14. The method of claim wherein the washed keratin fibers are subsequently contacted with the same or a different one of said curl minimizing composition, said subsequent contact optionally being heat-assisted.
