Abstract

The present invention generally relates to fluorescent marking compositions and their use to determine whether a surface has been cleaned. More particularly, the marking compositions comprise fluorescent polymers.

First claim

What is claimed is:

1. A method of determining if a location has been cleaned, the method comprising:
applying a fluorescent marking composition comprising a solvent and a water-dispersible fluorescent polymer to a location on an environmental surface; and
determining if any of the fluorescent polymer remains on the location after one or more opportunities to clean the environmental surface,
wherein the water-dispersible polymer is either derived from polymerization of one or more polymerizable fluorescent monomer units and one or more polymerizable non-fluorescent monomer units or is a conjugate of a fluorescent dye and a non-fluorescent polymer.

2. The method of claim 1 , wherein the water-dispersible fluorescent polymer is derived from polymerization of one or more polymerizable fluorescent monomer units and one or more polymerizable non-fluorescent monomer units.

3. The method of claim 1 , wherein the surface is a surface of a High Touch Object (HTO).

4. The method of claim 1 , wherein the surface is a surface in a hospital, a nursing home, long-term care facility, clinic, doctor's office, or dental office.

5. The method of claim 1 , wherein the surface is a surface in a restaurant, bar, nightclub, grocery store, hotel, bank, spa, health club, fitness center, locker room, day care center, indoor playground, school, convention center, office building, public restroom, movie theater, place of worship, public transit vehicle, airplane, taxicab, cruise ship, or ferry.

6. The method of claim 1 , wherein the marking composition is applied with an applicator comprising a spray applicator, a foam pad applicator, a felt tip applicator, a brush, a roll, a wipe, or a solid form.

7. The method of claim 1 , wherein the marking composition is applied with an applicator comprising a bottle or ampule.

8. The method of claim 1 , further comprising recording a result of the determining step.

9. The method of claim 8 , wherein the recording is done using a mobile application.

10. The method of claim 8 , wherein the result is stored as data.

11. The method of claim 10 , wherein the data is wirelessly transmitted.

12. The method of claim 10 , wherein the data is aggregated and analyzed.

13. The method of claim 10 , further comprising using the data to assess whether cleaning activities are consistent with nosocomial infection control efforts.

14. The method of claim 10 , further comprising preparing a report on the data.

15. The method of claim 14 , wherein the report comprises at least one of a percentage of High Touch Objects (HTOs) cleaned, a comparison against baseline data, an identification of areas for improvement, or a combination thereof.
