Abstract

A cleaning wipe comprising a nonwoven fabric wherein the nonwoven fabric is impregnated with an antibacterial cleaning composition.

Claims

1. A cleaning wipe which comprises approximately:

(a) 15 wt. % to 35 wt. % of a nonwoven fabric; and

(b) 65 wt. % to 85 wt. % of a liquid cleaning composition being impregnated in said nonwoven fabric, wherein said liquid cleaning composition comprises;

(i) 0.5 wt. % to 10 wt. % of at least one ethoxylated nonionic surfactant;

(ii) 0.25 wt. % to 10 wt. % of at least one C₁-C₄ alkanol;

(iii) 0.5 wt. % to 8 wt. % of a cosurfactant;

(iv) 0.1 wt. % to 2 wt. % of a disinfecting agent; and

(v) the balance being water, wherein the composition has a pH of about 5 to about 8 and the composition does not contain an anionic surfactant or a zwitterionic surfactant.

2. The cleaning wipe of claim 1, wherein said at least one nonionic surfactant comprises a mixture of two different nonionics, wherein one said nonionic surfactant is formed from a C₉-C₁₁ alkanol condensed with 7 to 9 moles of ethylene oxide and the other said nonionic surfactant is formed from a C₉-C₁₁ alkanol condensed with 2 to 3.5 moles of ethylene oxide.

3. The cleaning wipe of claim 1, wherein said C₁-C₄ alkanol is ethanol or isopropanol.

4. The cleaning wipe of claim 3, wherein said cosurfactant is a glycol ether.

5. The cleaning wipe of claim 1, wherein said glycol ether is propylene glycol N-butyl ether.

6. The cleaning wipe of claim 1, wherein said cosurfactant is glycol ether.

7. The cleaning wipe of claim 6, wherein said glycol ether is propylene glycol N-butyl ether.

8. The cleaning wipe of claim 4 further including a perfume.

9. The cleaning wipe of claim 8, wherein said disinfecting agent is a tetraalkyl ammonium salt or a trialkyl benzyl ammonium salt.

10. The cleaning wipe of claim 6 further including a perfume.

11. The cleaning wipe of claim 10, wherein said disinfecting agent is a tetraalkyl ammonium salt or a trialkyl benzyl ammonium salt.

12. The cleaning wipe of claim 1 wherein said disinfecting agent is a tetraalkyl ammonium salt or a trialkyl benzyl ammonium salt.
