Abstract

A composition having various color changing tannates may be used to indicate that the composition has dried. The tannates change color in contact with an acid. The composition may be, for example, a skin prep, skin sealant, food product, paint or other building material or other product that undergoes a phase change. The tannate may be added either directly to the composition, incorporated into a sponge on an applicator through which the composition is dispensed and applied, applied separately or applied simultaneously from a separate reservoir. The amount of tannate in the composition can be adjusted to provide a visual cue to the user of the application area and the extent of cure.

Claims

1. A composition comprising a tannate that changes color when said composition comes in contact with an acid.

2. The composition of claim 1, wherein said tannate is iron tannate.

3. The composition of claim 1, wherein said tannate is ferric tannate.

4. The composition of claims 1 which is applied over a skin preparation.

5. The composition of claim 1, wherein the color change is visible to the human eye under normal light conditions.

6. The composition of claim 1 comprising a cyanoacrylate-based resin.

7. The composition of claim 1 wherein said tannate is present in an amount between about 0.09 and 10 weight percent of the composition.

8. The composition of claim 1 wherein said tannate is impregnated onto a sponge which is used to apply said composition.

9. The composition of claim 1 wherein said tannate is applied separately to a surface from a separate reservoir to produce said composition.

10. The composition of claim 1 used to cover wounds, abrasions, burns, acne, blisters and other disruptions in the skin to protect the skin from subsequent contamination.

11. The composition of claim 10 wherein said skin is human or animal skin.

12. The composition of claim 1 used to close wounds.

13. The composition of claim 1 packaged in a “

kit”

form.

14. The composition of claim 1 which is bundled with an iodine-containing skin prep solution.

16. The medical kit of claim 14 further comprising an iodine-containing skin prep.

17. The medical kit of claim 14 wherein said tannate is impregnated onto a sponge which is used to apply said sealant.

15. A medical kit comprising a skin sealant and a tannate that changes color upon contact with an acid.
