Abstract

In one embodiment, a method of modeling interactions with keratinous tissue may comprise the steps of providing a nonwoven mimic and performing an act on the mimic as may be performed on keratinous tissue. The nonwoven mimic has a surface energy representative of keratinous tissue. In another embodiment, a method of modeling interactions with keratinous tissue may comprise the steps of: providing a mimic comprising from about 60% or greater rayon, from about 40% or less polyester, and a surface energy representative of keratinous tissue; and performing an act on the mimic as may be performed on keratinous tissue. The mimic is preferably a nonwoven mimic.

Claims (37)

1. A method of modeling interactions with keratinous tissue, comprising the steps of:

a) providing a nonwoven mimic having a surface energy representative of keratinous tissue; the nonwoven mimic comprising:

1. from 60% or greater Lyocel, and

2. from 40% or less polyethylene terephthalate;

b) applying an amount of substance to the mimic as may be applied to keratinous tissue; and

c) analyzing the nonwoven mimic to assess interaction of the substance with the mimic.

2. The method according to claim 1 wherein the substance is a shave preparation and the interaction assessed is in-shave or post-shave lubrication.

3. A method of modeling interactions with keratinous tissue, comprising the steps of:

a) providing a hydroentangled nonwoven mimic comprising:

1. from about 60% or greater Lyocel, and

2. from about 40% or less polyethylene terephthalate;

wherein the mimic has a surface energy representative of keratinous tissue; and

b) applying an amount of substance to the mimic as may be applied to keratinous tissue; and

c) analyzing the nonwoven mimic to assess interaction of the substance with the mimic.

4. The method according to claim 3 , wherein the interaction is deposition of the substance onto keratinous tissue.

5. The method according to claim 3 , wherein the interaction is removal of the substance from keratinous tissue.

6. The method according to claim 3 , wherein the interaction is adhesion of the substance to keratinous tissue.

7. The method according to claim 3 , wherein the interaction is modeling a regimen of more than one substance.

8. The method according to claim 3 , wherein the substance is selected from the group consisting of a consumer product, a natural substance, an imitation of a natural substance, and combinations thereof.

9. The method according to claim 3 , wherein the mimic demonstrates a total surface energy of from about 10 mJ/m 2 to about 55 mJ/m 2 .

10. The method according to claim 3 , wherein the mimic has a dry basis weight of between about 50 grams per square meter and 180 grams per square meter.

11. The method according to claim 3 , wherein the shape of the mimic is substantially planar.

12. The method according to claim 3 , further comprising the steps of:

a) generating a first set of data by performing at least one analysis of the mimic;

b) comparing the first set of data to a second set of data; and

c) generating predictive models based on the data comparison;

wherein the second set of data is consumer data.

13. The method according to claim 12 , wherein the second set of data is obtained by applying a substance to living keratinous tissue and performing at least one analysis of the tissue.

14. The method according to claim 3 wherein the substance is a shave preparation and the interaction assessed is in-shave or post-shave lubrication.

15. A device for modeling interactions with keratinous tissue, comprising:

a) a nonwoven mimic comprising:

1. from about 60% or greater Lyocel, and

2. from about 40% or less polyethylene terephthalate;

wherein the nonwoven mimic has a surface energy representative of keratinous tissue; and

b) an instrument used to simulate interactions with keratinous tissue;

wherein the nonwoven mimic and instrument are in physical contact with one another.

16. The device according to claim 15 wherein the interaction is effectiveness in reducing friction.
