Abstract

The present invention relates to novel compositions, which provide an indicator for location and/or concentration of the composition during application. In a preferred embodiment, the indicator is a compound that is visible at a first pH and invisible at a second pH. The composition includes the indicator and a volatile base or acid. The volatile base or acid enables the composition to be at a first pH so that the indicator is visible when first applied to a desired surface. However, upon evaporation or degradation of the volatile acid or base, the composition will be at a second pH, causing the indicator to disappear.

Claims

1. A method for making a customized composition for application to a surface wherein said method comprises selecting a material;

selecting a temporary visual indicator; and

mixing the indicator with the material to form the customized composition.

2. The method, according to claim 1, further comprising the step of mixing a modifying substance with the material, wherein the modifying substance enables the indicator to be visible for a desired period of time after application, and then disappears.

3. The method according to claim 2, wherein the indicator is a compound that is selected from the group consisting of phenolphthalein;

bromthymol blue;

thymol blue;

phenol red;

cresol red;

m-cresol purple;

methyl violet;

methyl orange;
