ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a nonwoven fabric which has been impregnated with an antibacterial liquid cleaning composition.
BACKGROUND OF THE INVENTION
The patent literature describes numerous wipes for both body cleaning and cleaning of hard surfaces but none describe the instant cleaning wipes which have improved cleaning characteristics in the minimization of streaking and residue.
U.S. Pat. Nos. 5,756,612; 5,763,332; 5,908,707; 5,914,177; 5,980,922 and 6,168,852 teach cleaning compositions which are inverse emulsions.
U.S. Pat. Nos. 6,183,315 and 6,183,763 teach cleaning compositions containing a proton donating agent and having an acidic pH.
U.S. Pat. Nos. 5,863,663; 5,952,043; 6,063,746 and 6,121,165 teaches cleaning compositions which are out in water emulsions.
SUMMARY OF THE INVENTION
An antibacterial cleaning wipe for cleaning hard surfaces such as walls, counter tops and floors comprises a nonwoven fabric containing at least polyester fibers and viscose fibers, wherein is the nonwoven fabric is impregnated with a liquid cleaning composition containing at least one nonionic surfactant, a disinfecting agent, a cosurfactant, an alkanol, water and optionally an anionic surfactant and a zwitterionic surfactant, wherein the liquid cleaning composition is not an emulsion and does not contain proteins, metallic salts, enzymes, amides, sodium hypochlorite, dimethicone, N-methyl-2-pyrrolidone, monoalkyl phosphate or silicon based sulfosuccinate.
DETAILED DESCRIPTION OF THE INVENTION
The present invention relates to an antibacterial cleaning wipe for hard surfaces which comprises approximately:
(a) 20 wt. % to 30 wt. % of a nonwoven fabric which consists of at least polyester fibers and viscose fibers and preferably consists of 60 wt. % to 95 wt. % of wood pulp fibers, 2.5 wt. % to 20 wt. % of viscose fibers and 2.5 wt. % to 20 wt. % of polyester fibers; and
(b) 70 wt. % to 80 wt. % of a liquid cleaning composition being impregnated in said nonwoven fabric, wherein said liquid cleaning composition comprises:
(i) 0.5 wt. % to 8 wt. %, more preferably 1.0 wt. % to 6 wt. % of at least one ethoxylated nonionic surfactant;
(ii) 0.25 wt. % to 10 wt. %, more preferably 0.5 wt. % to 6 wt. % of a C

alkanol;
(iii) 0.5 wt. % to 8 wt. %, more preferably 1 wt. % to 5 wt. % of a cosurfactant;
(iv) 0 to 15 wt. %, more preferably 0.25 wt. % to 10 wt. % of an anionic surfactant;
(v) 0 to 5 wt. %, more preferably 0.25 wt. % to 4 wt. % of a zwitterionic surfactant;
(vi) 0.1 wt. % to 2 wt. %, more preferably 0.2 wt. % to 1.4 wt. % of a disinfecting agent;
(vii) the balance being water, wherein the composition has a pH of about 5.5 to about 7, more preferably about 5.8 to about 6.6.
The composition can also optionally contain a water-soluble zwitterionic surfactant (betaine), which may be used in the instant cleaning composition, constitutes about 0 to 5%, preferably 0.1% to 5%, by weight and provides good foaming properties and mildness to the composition. The zwitterionic surfactant is a water soluble betaine having the general formula:

As used herein and in the appended claims the term “perfume” is used in its ordinary sense to refer to and include any non-water soluble fragrant substance or mixture of substances including natural (i.e., obtained by extraction of flower, herb, blossom or plant), artificial (i.e., mixture of natural oils or oil constituents) and synthetically produced substance) odoriferous substances. Typically, perfumes are complex mixtures of blends of various organic compounds such as alcohols, aldehydes, ethers, aromatic compounds and varying amounts of essential oils (e.g., terpenes) such as from 0% to 80%, usually from 10% to 70% by weight, the essential oils themselves being volatile odoriferous compounds and also serving to dissolve the other components of the perfume.
In the present invention the precise composition of the perfume is of no particular consequence to cleaning performance so long as it meets the criteria of water immiscibility and having a pleasing odor. Naturally, of course, especially for cleaning compositions intended for use in the home, the perfume, as we
