ABSTRACT:

FIELD OF INVENTION
The present invention relates to a cleaning wipe which is single layer fabric substrate has been impregnated with a liquid cleaning composition.
BACKGROUND OF THE INVENTION

Nos. 5,980,931, 6,063,397 and 6,074,655 teach a substantially dry disposable personal cleansing product useful for both cleansing and conditioning the skin and hair. U.S. Pat. No. 6,060,149 teaches a disposable wiping article having a substrate comprising multiple layers.
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 oil in water emulsions.
SUMMARY OF THE INVENTION
A single use cleaning wipe for dishwashing application comprises a water insoluble substrate, impregnated with a cleaning composition containing an anionic sulfonated surfactant, an alkyl polyglucoside surfactant, an alkyl monoalkanol amide, an ethoxylated alkyl ether sulfate surfactant, a C

The present invention also relates to a cleaning wipe which comprises approximately:
(a) 20 wt. % to 95 wt. % of a water insoluble substrate;
(b) 5 wt. % to 80 wt. % of a liquid cleaning composition being impregnated in said water insoluble substrate, wherein said liquid cleaning composition comprises:
(i) 2 wt. % to 12 wt. % of an alkaline earth metal salt of a sulfonate surfactant;
(ii) 2 wt. % to 12 wt. % of an alkali metal salt of a sulfonate surfactant;
(iii) 5 wt. % to 18 wt. % of an alkali metal salt of an ethoxylated alkyl ether sulfate surfactant;
(iv) 5 wt. % to 18 wt. % of an alkyl polyglucoside surfactant;
(v) 1 wt. % to 10 wt. % of an amine oxide surfactant;
(vi) 1 wt. % to 8 wt. % of a C

alkanol;
(vii) 0.5 wt. % to 6 wt. % of sodium xylene sulfonate and/or sodium cumene sulfonate; and
(viii) the balance being water.
Suitable water-soluble non-soap, anionic surfactants used in the instant compositions include those surface-active or detergent compounds which contain an organic hydrophobic group containing generally 8 to 26 carbon atoms and preferably 10 to 18 carbon atoms in their molecular structure and at least one water-solubilizing group selected from the group of sulfonate, sulfate and carboxylate so as to form a water-soluble detergent. Usually, the hydrophobic group will include or comprise a C

-C

alkyl, alkyl or acyl group. Such surfactants are employed in the form of water-soluble salts and the salt-forming cation usually is selected from the group consisting of sodium, potassium, ammonium, magnesium and mono-, di- or tri-C

-C

alkanolammonium, with the sodium, magnesium and ammonium cations again being preferred.
Examples of suitable sulfonated anionic surfactants are the well known higher alkyl mononuclear aromatic sulfonates such as the higher alkyl benzene sulfonates containing from 10 to 16 carbon atoms in the higher alkyl group in a straight or branched chain, C

-C
15
alkyl toluene sulfonates and C

alkyl phenol sulfonates.
A preferred sulfonate is linear alkyl benzene sulfonate having a high content of 3-(or higher) phenyl isomers and a correspondingly low content (well below 50%) of 2-(or lower) phenyl isomers, that is, wherein the benzene ring is preferably attached in large part at the 3 or higher (for example, 4, 5, 6 or 7) position of the alkyl group and the content of the isomers in which the benzene ring is attached in the 2 or 1 position is correspondingly low.
Other suitable anionic surfactants are the olefin sulfonates, including long-chain alkene sulfonates, long-chain hydroxyalkane sulfonates or mixtures of alkene sulfonates and hydroxyalkane sulfonates. These olefin sulfonate detergents may be prepared in a known manner by the reaction of sulfur trioxide (SO
3
) with long-chain olefins containing 8 to 25, preferably 12 to 21 carbon atoms and having the formula RCH═CHR
1
where R is a higher alkyl group of 6 to 23 carbons and R
1
is an alkyl group of 1 to 17 carbons or hydrogen to form a mixture of sultones and alkene sulfonic acids which is then treated to convert the sultones to sulfonates. Preferred olefin sulfonates contain from 14 to 16 carbon atoms in the R alkyl group and are obtained by sulfonating an &agr;-olefin.
Other examples of suitable anionic sulfonate surfactants are the paraffin sulfonates containing 10 to 20, preferably 13 to 17, carbon atoms. Primary paraffin sulfonates are made by reacting long-chain alpha olefins and bisulfites and paraffin sulfonates having the sulfonate group distributed along the paraffin chain are shown in U.S. Pat. Nos. 2,503,280; 2,507,088; 3,260,744; 3,372,188; and German Patent 735,096.
Examples of satisfactory anionic sulfate surfactants are the C

M wherein n is 1 to 12, preferably 1 to 5, and M is a metal cation selected from the group consisting of sodium, potassium, ammonium, magnesium and mono-, di- and triethanol ammonium ions. The alkyl sulfates may be obtained by sulfating the alcohols obtained by reducing glycerides of coconut oil or tallow or mixtures thereof and neutralizing the resultant product.
On the other hand, the ethoxylated alkyl ether sulfates are obtained by sulfating the condensation product of ethylene oxide with a C

alkanol and neutralizing the resultant product. The alkyl sulfates may be obtained by sulfating the alcohols obtained by reducing glycerides of coconut oil or tallow or mixtures thereof and neutralizing the resultant product. The ethoxylated alkyl ether sulfates differ from one another in the number of moles of ethylene oxide reacted with one mole of alkanol. Preferred alkyl sulfates and preferred ethoxylated alkyl ether sulfates contain 10 to 16 carbon atoms in the alkyl group.
The ethoxylated C

alkylphenyl ether sulfates containing from 2 to 6 moles of ethylene oxide in the molecule also are suitable for use in the inventive compositions. These surfactants can be prepared by reacting an alkyl phenol with 2 to 6 moles of ethylene oxide and sulfating and neutralizing the resultant ethoxylated alkylphenol.
