Abstract

A method of treating a surface is provided. The method includes disposing a condensation reduction composition on the surface, thereby treating the surface to reduce formation of condensate and/or an amount of condensate thereon. The condensation reduction composition comprises a surface-active agent comprising an alkyl polyglycoside. The condensation reduction composition may further comprise a preservative, a pH control agent, and/or water. A treated surface prepared in accordance with the method is also provided. The method and treated surface prepared therewith are useful in reducing condensate and/or formation of condensate on surfaces, e.g. by reducing the number of condensate drops falling from the surface, increasing the rate of condensate evaporation on the surface, and/or increasing the rate of water absorption into or through the surface, e.g. upon or during exposure of the treated surface to a condensation condition.

Claims (20)

1. A method of treating a surface to reduce condensate and/or formation of condensate thereon, said method comprising:

disposing a condensation reduction composition on the surface which is defined as an overhead surface that is a surface of a structure disposed above an area at a height sufficient for a person to stand and/or sit underneath, the overhead surface being a porous, horizontal surface that is a concrete ceiling of a room in a food processing facility, the condensation reduction composition comprising a surface-active agent comprising an alkyl polyglycoside, thereby treating the surface to reduce formation of condensate and/or an amount of condensate thereon.

2. The method of claim 1 , wherein the condensation reduction composition comprises the surface-active agent in an amount of from 0.0005 to 100 wt. %, based on the total weight of the condensation reduction composition.

3. The method of claim 1 , wherein the surface-active agent comprises a C8-C16 alkyl polyglucoside.

4. The method of claim 3 , wherein the condensation reduction composition comprises the C8-C16 alkyl polyglucoside in an amount of from 0.07 to 30 wt. %, based on the total weight of the condensation reduction composition.

5. The method of claim 1 , wherein the condensation reduction composition further comprises (B) a preservative.

6. The method of claim 5 , wherein the preservative: (i) comprises sodium benzoate; (ii) is present in the condensation reduction composition in an amount of from 0.001 to 1 wt. %, based on the total weight of the condensation reduction composition; or (iii) both (i) and (ii).

7. The method of claim 1 , wherein the condensation reduction composition comprises a pH of from 2.0 to 12.5.

8. The method of claim 1 , wherein the condensation reduction composition further comprises a pH control agent.

9. The method of claim 8 , wherein the condensation reduction composition comprises the pH control agent in an amount of from 0.01 to 6 wt. %, based on the total weight of the condensation reduction composition.

10. The method of claim 8 , wherein the pH control agent comprises: (i) sodium citrate; (ii) citric acid; or (iii) both (i) and (ii).

11. The method of claim 10 , wherein the pH control agent comprises the sodium citrate, and wherein the condensation reduction composition comprises the sodium citrate in an amount of from 0.0003 to 0.1 wt. %, based on the total weight of the condensation reduction composition.

12. The method of claim 10 , wherein the pH control agent comprises the citric acid, and wherein the condensation reduction composition comprises the citric acid in an amount of from 0.01 to 5 wt. %, based on the total weight of the condensation reduction composition.

13. The method of claim 1 , wherein the condensation reduction composition comprises water in an amount of from 65 to 99.9 wt. %, based on the total weight of the condensation reduction composition.

14. The method of claim 1 , further comprising: (i) preparing the condensation reduction composition prior to disposing the condensation reduction composition on the surface; or (ii) preparing the condensation reduction composition on the surface.

15. The method of claim 1 , wherein the condensation reduction composition is disposed on the surface as: (i) a spray; (ii) an aerosol; (iii) a solution; (iv) a foam; or (v) any combination of (i)-(iv).

16. The method of claim 1 , wherein disposing the condensation reduction composition on the surface comprises applying the condensation reduction composition to the surface via: (i) spraying; (ii) brushing; (iii) mopping; or (iv) any combination of (i)-(iii).

17. The method of claim 1 , further comprising: (i) exposing the surface to a condensation condition subsequent to disposing the condensation reduction composition on the surface: (ii) exposing the surface to a condensation condition concurrently with disposing the condensation reduction composition on the surface; or (iii) both (i) and (ii).

18. The method of claim 1 , wherein reducing the amount of condensate and/or formation of condensate on the surface comprises: (i) reducing a number of condensate drops falling from the surface during exposure to a condensation condition; (ii) increasing a rate of condensate evaporation on the surface during exposure to a condensation condition; (iii) increasing a rate of water absorption into or through the surface; or (iv) any combination of (i)-(iii).

19. A treated surface prepared in accordance with the method of claim 1 .
