ABSTRACT:

FIELD OF INVENTION
The present invention relates to a nonwoven fabric which has been impregnated with a liquid glass 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 glass 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
A glass cleaning wipe comprising a nonwoven fabric containing wood pulp fibers, wherein is the nonwoven fabric is impregnated with a liquid glass cleaning composition containing an anionic surfactant, a cosurfactant, an alkanol, a quaternary alkylol amine salt and water, wherein the liquid glass cleaning composition is not an emulsion and does not contain proteins, metallic salts, enzymes, amides, sodium hypochlorite, dimethicone, a proton donating agent, N-methyl-2-pyrrolidone, monoalkyl phosphate or silicon based sulfosuccinate.
DETAILED DESCRIPTION OF THE INVENTION
The present invention relates to a glass cleaning wipe which comprises approximately:
(a) 30 wt. % to 40 wt. % of a nonwoven fabric consisting of 60 wt. % to 95 wt. % of wood pulp fibers, 2.5 wt. % to 10 wt. % of viscose fibers and 2.5 wt. % to 10 wt. % of polyester fibers; and
(b) 60 wt. % to 70 wt. % of a liquid glass cleaning composition being impregnated in said nonwoven fabric, wherein said liquid glass cleaning composition comprises:
(i) 0.1 wt. % to 5 wt. %, 0.25 wt. % to 4 wt. % of an anionic surfactant;
(ii) 0.5 wt. % to 10 wt. %, more preferably 1 wt. % to 6 wt. % of a C

4
alkanol;
(iii) 0.5 wt. % to 8 wt. %, more preferably 1 wt. % to 5 wt. % of a cosurfactant;
(iv) 0.1 wt. % to 1 wt. %, more preferably 0.2 wt. % to 0.8 wt. % of an antirain or antidust agent, a cationic quaternary alkylolamine salt, or choline chloride;
(v) 0 to 0.25 wt. %, more preferably 0.01 wt. % to 0.1 wt. % of a perfume;
(vi) 0 to 0.1 wt. %, more preferably 0.01 wt. % to 0.1 wt. % of a preservative such as iodo propynyl butyl carbanate; and
(vii) the balance being water, wherein the composition has a pH of about 7 to about 9.5, more preferably about 7.5 to about 8.5.
The anionic surfactant used in the instant invention are selected from the group consisting of sulfate anionic surfactants and sulfonate anionic surfactants, wherein the preferred anionic surfactant is a C
8
-C
18
ethoxylated alkyl ether sulfate surfactant.
The anionic sulfonate surfactants which may be used in the detergent of this invention are water soluble and include the sodium, potassium, ammonium and ethanolammonium salts of linear C
8
-C
16
alkyl benzene sulfonates; C
10
-C
20
paraffin sulfonates, alpha olefin sulfonates containing about 10-24 carbon atoms and C
8
-C
18
ethoxylated alkyl ether sulfates and mixtures thereof. The preferred anionic sulfonate surfactant is a C
12-18
paraffin sulfonate.
The paraffin sulfonates may be monosulfonates or di-sulfonates and usually are mixtures thereof, obtained by sulfonating paraffins of 10 to 20 carbon atoms. Preferred paraffin sulfonates are those of C
12-18
carbon atoms chains, and more preferably they are of C
14-17
chains. Paraffin sulfonates that have the sulfonate group(s) distributed along the paraffin chain are described in U.S. Pat. Nos. 2,503,280; 2,507,088; 3,260,744; and 3,372,188; and also in German Patent 735,096. Such compounds may be made to specifications and desirably the content of paraffin sulfonates outside the C
14-17
range will be minor and will be minimized, as will be any contents of di- or poly-sulfonates.
Examples of suitable other sulfonated anionic detergents are the well known higher alkyl mononuclear aromatic sulfonates, such as the higher alkylbenzene sulfonates containing 9 to 18 or preferably 9 to 16 carbon atoms in the higher alkyl group in a straight or branched chain, or C
8-15
alkyl toluene sulfonates. A preferred alkylbenzene sulfonate is a linear alkylbenzene sulfonate having a higher content of 3-phenyl (or higher) isomers and a correspondingly lower content (well below 50%) of 2-phenyl (or lower) isomers, such as those sulfonates wherein the benzene ring is attached mostly 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. Preferred materials are set forth in U.S. Pat. No. 3,320,174, especially those in which the alkyls are of 10 to 13 carbon atoms.
The C
8-18
ethoxylated alkyl ether sulfate surfactants have the structure
R—(OCHCH
2
)
n
OSO
3

M
+
wherein n is about 1 to about 22 more preferably 1 to 3 and R is an alkyl group having about 8 to about 18 carbon atoms, more preferably 12 to 15 and natural cuts, for example, C
12-14
or C
12-16
and M is an ammonium cation or a metal cation, most preferably sodium.
The ethoxylated alkyl ether sulfate may be made by sulfating the condensation product of ethylene oxide and C
8-10
alkanol, and neutralizing the resultant product. The ethoxylated alkyl ether sulfates differ from one another in the number of carbon atoms in the alcohols and in the number of moles of ethylene oxide reacted with one mole of such alcohol. Preferred ethoxylated alkyl ether polyethenoxy sulfates contain 12 to 15 carbon atoms in the alcohols and in the alkyl groups thereof, e.g., sodium myristyl (3 EO) sulfate.
Ethoxylated C
8-18
alkylphenyl ether sulfates containing from 2 to 6 moles of ethylene oxide in the molecule are also suitable for use in the invention compositions. These detergents can be prepared by reacting an alkyl phenol with 2 to 6 moles of ethylene oxide and sulfating and neutralizing the resultant ethoxylated alkylphenol.
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. The instant compositions show a marked improvement in ecotoxocity as compared to existing commercial products.
The cosurfactants in the instant compositions are selected from the group consisting of polypropylene glycol of the formula HO(CH
