Abstract

The invention relates to a method of retaining, enhancing or imparting curl in a keratinous material which comprises applying to the keratinous material a retention effective amount of a transglutaminase enzyme.

Claims

1. A method of retaining curl in human eyelashes which comprises applying to the eyelashes a composition containing a transglutaminase in an amount of from about 0.004% to about 0.025% by weight of the composition.

2. The method of claim 1 in which the composition has a pH of about 6 to about 7.

3. The method of claim 1 in which the eyelashes already have a natural curl or have been artificially curled.

4. The method of claim 3 in which the application of the composition is followed by the application of heat.

5. The method of claim 1 in which the transglutaminase is present in the composition in an amount of from about 0.006% to about 0.017% by weight.

6. The method of claim 5 in which the transglutaminase is present in the composition in an amount of from about 0.0086% to about 0.0135% by weight.

7. The method of claim 1 in which the transglutaminase is a microbial transglutaminase.

8. The method of claim 1 in which the transglutaminase is a mammalian transglutaminase.

9. A method of enhancing curl in human eyelashes which comprises applying to the human eyelashes a composition containing a transglutaminase in an amount of from about 0.004% to about 0.025% by weight of the composition.

10. The method of claim 9 in which the composition has a pH of about 6 to about 7.

11. The method of claim 10 in which the human eyelashes already have a natural curl or have been artificially curled.

12. The method of claim 11 in which the application of the composition is followed by the application of heat.

13. The method of claim 9 in which the transglutaminase is present in the composition in an amount of from about 0.006% to about 0.017% by weight.

14. The method of claim 13 in which the transglutaminase is present in the composition in an amount of from about 0.0086% to about 0.0135% by weight.

15. The method of claim 9 in which the transglutaminase is a microbial transglutaminase.

16. The method of claim 9 in which the transglutaminase is a mammalian transglutaminase.
