## Abstract

Method of assessing the adhesion of soils or exudates to the skin. The method may allow for an assessment of the amount of artificial bowel movement remaining on the skin following treatment with a lotion.

## Claims

### Claim 1

A method to assess artificial bowel movement removal from skin comprising the steps of:
a. applying the artificial bowel movement to the skin;
b. applying weigh paper to the artificial bowel movement;
c. using the weigh paper to remove at least a portion of the artificial bowel movement by slowly peeling the weigh paper upwards, from a first corner of the weigh paper toward a second corner diagonally opposite the first corner; and
d. weighing the weigh paper to determine the amount of artificial bowel movement associated with the weigh paper.

### Claim 2 (depends on 1)

The method of claim 1 further comprising the step of applying about 0.5 psi of downward force to the weigh paper.

### Claim 3 (depends on 2)

The method of claim 2 wherein the downward force is applied for a duration of about 30 seconds.

### Claim 4 (depends on 1)

The method of claim 1 wherein about 0.2 ml of artificial bowel movement is applied to the skin.

### Claim 5 (depends on 1)

The method of claim 1 wherein the skin is treated with a lotion.

### Claim 6 (depends on 5)

The method of claim 5 wherein the skin is treated with the lotion prior to the application of the artificial bowel movement.

### Claim 7 (depends on 5)

The method of claim 5 wherein the skin is treated with about 1 μ/cm2 of the lotion.

### Claim 8 (depends on 5)

The method of claim 5 wherein at least two different lotions are applied to the skin to assess the artificial bowel movement removal from skin after application of each of the lotions.

### Claim 9 (depends on 8)

The method of claim 8 wherein each of the lotions is applied to a different test site on the skin.

### Claim 10

A method to assess artificial bowel movement removal from skin comprising the steps of:
a. applying a lotion to the skin;
b. applying the artificial bowel movement to the skin;
c. applying weigh paper to the artificial bowel movement;
d. applying about 0.5 psi of a downward force to the weigh paper;
e. using the weigh paper to remove at least a portion of the artificial bowel movement by slowly peeling the weigh paper upwards, from a first corner of the weigh paper toward a second corner diagonally opposite the first corner; and
f. weighing the weigh paper to determine the amount of artificial bowel movement associated with the weigh paper.

### Claim 11 (depends on 10)

The method of claim 10 wherein the skin is treated with about 1 μ/cm2 of the lotion.

### Claim 12 (depends on 10)

The method of claim 10 wherein the artificial bowel movement is applied to the lotion-treated skin.

### Claim 13 (depends on 10)

The method of claim 10 wherein the downward force is applied for a duration of about 30 seconds.

### Claim 14 (depends on 10)

The method of claim 10 wherein at least two different lotions are applied to the skin to assess the artificial bowel movement removal from skin after application of each of the lotions.

### Claim 15 (depends on 14)

The method of claim 14 wherein each of the lotions is applied to a different test site on the skin.
