ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a nonwoven fabric which has been impregnated with a liquid cleaning composition that provides a lasting antibacterial protection of hard surfaces.
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 deliver a lasting antibacterial protection of hard surfaces and a 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
A cleaning wipe for cleaning and lasting antibacterial protection of hard surfaces such as walls, toilet bowl, bath tub, door handle, tables, 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 comprises an anionic surfactant and a polycationic antibacterial agent, a nonionic surfactant, an emulsifier, optionally, a perfume, optionally, a proton donating agent, optionally, cosurfactants and solvents and water, 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) a complex of 0.01% to 5.0%, more preferably 0.1% to 0.5% of an anionic surfactant and 0.01% to 2%, more preferably 0.04% to 0.2% of a cationic polymer selected from the group consisting of poly (hexamethylene biguanide) hydrochloride having the structure of:
where the average n=4 to 6 or from the group consisting of quaternized cationic polymer having the structure of
(ii) 0 to 10%, more preferably 0.25% to 5% of at least one water soluble cosurfactant;
(iii) 0 to 1%, more preferably 0.01% to 1% of an emulsifier or ethoxylated nonionic surfactant;
(iv) 0 to 0.75%, more preferably 0.05% to 0.4% of a fragrance or essential oil;
(v) 0 to 5%, more preferably 0.05% to 4% of a proton donating agent;
(vi) 0 to 6%, more preferably 0.1% to 5% of a C

alkanol such as isopropanol or ethanol; and
(vii) the balance being water, wherein the composition does not contain silver ions, an anionic surfactant as crosslinking agent, poly (hexamethylene biguanide) stearate or a cationic surfactant such as a quaternary ammonium compound.
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 well as all other ingredients, should be cosmetically acceptable, i.e., non-toxic, hypoallergenic, etc.
Suitable essential oils are selected from the group consisting of: Anethole 20/21 natural, Aniseed oil china star, Aniseed oil globe brand,, Balsam (Peru), Basil oil (India), Black pepper oil, Black pepper oleoresin 40/20, Bois de Rose (Brazil) FOB, Borneol Flakes (China), Camphor oil, White, Camphor powder synthetic technical, Cananga oil (Java), Cardamom oil, Cassia oil (China), Cedarwood oil (China) BP, Cinnamon bark oil, Cinnamon leaf oil, Citronella oil, Clove bud oil, Clove leaf, Coriander (Russia), Coumarin 69° C.

The water soluble nonionic surfactants utilized in this invention are commercially well known and include the primary aliphatic alcohol ethoxylates, secondary aliphatic alcohol ethoxylates, alkylphenol ethoxylates and ethylene-oxide-propylene oxide condensates on primary alkanols, such a Plurafacs (BASF) and condensates of ethylene oxide with sorbitan fatty acid esters such as the Tweens (ICI). The nonionic synthetic organic detergents generally are the condensation products of an organic aliphatic or alkyl aromatic hydrophobic compound and hydrophilic ethylene oxide groups. Practically any hydrophobic compound having a carboxy, hydroxy, amido, or amino group with a free hydrogen attached to the nitrogen can be condensed with ethylene oxide or with the polyhydration product thereof, polyethylene glycol, to form a wate
