Abstract

A method is provided for measuring the interaction of a disinfecting composition with a floor wax. The method include coating a surface with floor wax, allowing the coating to dry, applying a selected amount of disinfecting composition to the coated surface, and measuring, after a pre-determined amount of time, the tack of the surface, by using a controlled force measurement inverted probe machine. A detectable amount of tack indicates that the disinfecting composition has interacted with the floor wax. Alternatively, any tacky residue on the dried product surface may be sampled and analyzed by Fourier transform spectroscopy. Absorption at a wavelength associated with the floor wax indicates that the product has interacted with the floor wax. A foamable disinfecting composition having reduced interaction with floor wax is also provided.

Claims

1. A method for measuring the interaction of a disinfecting composition with a floor wax, the method comprising the steps of:

coating a surface with floor wax,

allowing the coating to dry,

applying a selected amount of disinfecting composition to the coated surface, and

measuring, after a pre-determined amount of time, the tack of the surface, by using a controlled force measurement inverted probe machine, wherein a detectable amount of tack indicates that the disinfecting composition has interacted with the floor wax.

2. The method of claim 1, wherein the disinfecting composition is a foamable alcoholic composition.

3. The method of claim 1, wherein the disinfecting composition comprises:

at least about 40 wt. % of a C_1-6 alcohol, based upon the total weight of the disinfecting composition;

a foaming surfactant selected from the group consisting of fluorosurfactants and siloxane-based polymer surfactants; and

at least about 0.4 wt. % of glycerin, based upon the total weight of the composition.

4. The method of claim 3, wherein the foaming surfactant is selected from the group consisting of siloxane polymer surfactants.

5. The method of claim 4, wherein the composition comprises from about 0.002 to about 4 wt. % of foaming surfactant, based upon the total weight of the disinfecting composition

6. The method of claim 4, wherein the amount of glycerin relative to the amount of siloxane polymer surfactant, on a weight basis, is from about 1:

0.5 to about 1;

7.

7. The method of claim 1, wherein the composition comprises from about 0.4 to about 5 wt. % of glycerin.

8. The method of claim 1, wherein the composition does not interact with floor wax to produce a tack of greater than 130 grams, when tested at standard temperature and pressure, using a controlled force measurement inverted probe machine having a stainless steel flat probe having a diameter of about 0.187 inches, and applying about 100 grams of force for about 5 seconds, after a contact time of about 2 weeks.

9. A foamable disinfecting composition comprising:

at least about 40 wt. % of a C_1-6 alcohol, based upon the total weight of the disinfecting composition;

a foaming surfactant selected from the group consisting of fluorosurfactants and siloxane-based polymer surfactants; and

from about 0.4 to about 5 wt. % of glycerin, based upon the total weight of the composition, wherein the composition exhibits reduced interaction with floor wax when compared to the same composition but containing less than about 0.4 wt. % of glycerin, based upon the total weight of the composition.

10. The composition of claim 9, wherein the foaming surfactant is selected from the group consisting of siloxane-based polymer surfactants.

11. The composition of claim 9, wherein the composition comprises from about 0.002 to about 4 wt. % of foaming surfactant, based upon the total weight of the disinfecting composition

12. The composition of claim 10, wherein the amount of glycerin relative to the amount of siloxane polymer surfactant, on a weight basis, is from about 1:

0.5 to about 1;

7.

13. The composition of claim 10, wherein the composition comprises from about 0.4 to about 5 wt. % of glycerin.

14. A method for measuring the interaction of an alcoholic disinfecting composition with a floor wax, the method comprising the steps of:

coating a surface with floor wax,

allowing the coating to dry,

applying an amount of the disinfecting composition to the coated surface, sufficient to form a thin layer over the coated surface,

allowing the disinfecting composition to dry, thereby forming a disinfectant layer,

sampling the disinfectant layer, by swabbing or blotting the disinfectant layer,

testing the sample by Fourier Transform Infrared analysis,

measuring the absorption of the sample at a pre-selected wavelength that correlates to the floor wax control and that does not correlate to the disinfecting composition, wherein measurable absorbance at said wavelength indicates that interaction has occurred.
