e t 0 a r DISINFECTANT WIPE BACKGROUND OF THE INVENTION i I. Field of the Invention The invention relates to a wipe for cleaning ii 5! and disinfecting non-absorbent surfaces, more specifically to a dry wipe which has incorporated therein a disinfecting agent and a surface active agent and is activated by the user for cleaning and/or disinfecting applications by wetting i with water.

!i 30 2. Information Disclosure Statement In response in recent years to a need for fast and convenient means to effect cleaning and/or disinfection i in household, personal hygiene and similar applications, j various disposable wiping articles have been suggested.

U.S. Patent 3,227,614 describes a disposable germicidal or bacteriostatic paper or tissue which may be used wet or dry to wipe surfaces to render them germicidal or bacteriostatic. Preferred germicidal and bacteriostatic agents are quaternary ammonium compounds including, amongst others, certain alkyl dimethyl benzyl (and ethyl benzyl) ammonium chlorides. An alcohol-type detergent as well as £certain other agents optionally can be employed. The germicidal and bacteriostatic agent and any optional agent is incorporated in the paper or tissue by treating the paper or tissue with a non-aqueous vehicle in which these agents i H are distributed. The alcohol-type detergent is incorporated in the treating solution in order to enhance the stability of the treating composition and is present in substantial weight excess over the quaternary ammonium compound.

I 5 U.S. Patent 3,786,615 discloses pre-moistened i antimicrobial towels useful for sanitation purposes. The i- towels may be made from paper having substantial wet strength or from woven or non-woven cloth made of rayon, nylon or i! cotton. The preferred antimicrobial compounds are quaternary j 10 ammonium compounds, C8_ 1 8 alkyl-substituted dimethyl if *benzyl ammonium chloride. A concentration of 0.1-0.2 mg.

of quaternary ammonium compound per square inch of towelling .i is generally used.

U.S. Patent 4,575,391 discloses a disposable pre-moistened toilet seat disinfectant wipe for individually i sanitizing a toilet seat. The wipe embodies a pad the material i of which may be of fibrillated cellulose, fluffed .cotton .t or wool fiber or disintegrated wood pulp, or of several t~ c layers of ordinary facial tissue. The disinfectant is a sanitizing solution such as an alcoholic solution, a silver i nitrate solution, a diluted sodium hypochlorite solution and a mercury-zinc cyanide solution. The wipe is provided with a stiff backing and a thumb tab to provide control of the wipe by the user.

U.S. Patent 4,311,479 discloses an article for wiping soiled surfaces consisting of a substrate of cloth, r" K.e^«i!^wlWill ««M«^li^>«l«ata^j5il^^Jg^'K^ -3paper or other non-woven material which may be impregnated with an antimicrobial compound such as a quaternary ammonium compound, a bisquanide, an antimicrobial amphoteric surfactant and mixtures thereof and having applied thereto a dye which will bond to the impregnant more than to the substrate and the disappearance whereof will indicate to the user diminution of the impregnant in the substrate. The subftrate may be dried if necessary, to the extent it is dry to the Stouch.

U.S. Patent 4,476,251 discloses a polyurethane Sfoam having cleaning and germicidal activities. The polyure- I thane foam is prepared from a select reaction mixture incorporating the active ingredients and includes a nonionic surfac- S:c tant, a quaternary ammonium compound and a silicon based j <l 15 surfactant. A particularly preferred embodiment employs, S, as the quaternary ammonium compound, a mixture of n-alkyl-

(C

12 18 )dimethyl benzyl ammonium chlorides and n-alkyl(C 12 18 dimethyl ethylbenzyl ammonium chlorides.

I'-iI Dry disinfectant wipes offer a number of advantages over pre-moistened wipes amongst which are less degradation of active ingredients, particularly the disinfecting agent, reduced shipping weight and fewer restrictions in packaging requirements, in the type of packaging material which can be used.

LI_

-4- The present invention provides an improved dry wipe which is intended for single-use and is activated for use by the addition of water. The dry wipe has distributed thereon an antimicrobial quaternary ammonium compound and a nonionic surfactant and is ideally suited for the disinfection and cleaning of soiled non-absorbent surfaces such as, toilet seats, sinks, counter tops, in a convenient and fast one-step procedure. The improvement resides in the discovery that when the quaternary ammonium compound and the nonionic surfactant are employed in the wipe in certain critical amounts, the active agents are transferred during the cleaning procedure from the moistened wipe onto the surface in amounts which are effective for cleaning and disinfection of the surface while at the same time S 5 such amounts are not so excessive as to be perceived as unsightly residues, as spots, smears or streaks, therefore precluding the need for rinsing and mechanical drying, a distinct advantage for the consumer both in terms of convenience and time.

Thus the invention provides a dry wipe which on contact with water provides a moist, flexible wipe for cleaning and disinfecting non-absorbent surfaces comprising an absorbent paper substrate which is uniformly coated per square foot thereof with: from about 0.03g to about 0.45g of a water-soluble antimicrobial quaternary ammonium compound; from about 0.002g to about 0.03g of a nonionic surface active agent; and from Og to about 0.3g of a fragrance.

Preferably the wipe comprises, per square foot of the paper substrate, from about 0.03g to about 0.3g of the quaternary ammonium compound and from about O.Olg to about 0.03g of the nonionic surface active agent.

DETAILED DESCRIPTION OF THE INVENTION INCLUDING THE PREFERRED EMBODIMENTS The term "dry wipe" as used herein means such a wipe devoid of any substantial amount of liquid other than such amount that may inherently be present in the paper substrate by virtue of hydrogen bonding or other attractive forces. Thus no substantial amount of liquid which is readily 0"15 evaporable when exposed to ambient air at room or elevated temperatures not detrimental to the dry wipe, such as the liquids employed in the preparation of the dry wipe as more fully disclosed hereinafter, is present in the dry wipe.

The dry wipe is comprised of three essential components: an absorbent paper substrate, an antimicrobial quaternary ammonium compound and a nonionic surface active agent.

°on Paper Substrate The paper substrate can be in any form convenient for wiping nonabsorbent surfaces but is preferably iin sheet-like form. It is derived from any paper stock which is produced by any of the well known manufacturing methods and which contains primarily wood pulp fibers, i.e., about 00o 0 04 JLH/303S

-6repercent by weight or more of wood pulp fibers, the remainder of the fibers being synthetic fibers such as rayon, nylon, orlon and polyester. The paper should have a wet strength sufficient to preclude disintegration of the wipe during the surface cleaning procedure.

Wet strength of varying degrees is imparted to paper by incorporating therein during manufacture appropriate amounts of a wet strength resin. However, because quaternary ammonium compounds have a certain degree of substantivity to wet strength resins, the paper employed in the invention preferably should contain an amount of wet strength resin substantially no greater than that which will provide wet strength to prevent disintegration during clqaning so as not to lead to excessive retention of the quaternary ammonium compound in the wipe. Therefore, the paper employed preferably should contain an amount of resin which provides a wet strength of less than about 30 percent, more preferably about 15 percent to 20 percent. Furthermore, although paper having these preferred wet strengths will not disintegrate during the cleaning procedure employed in accordance with the invention, nonetheless it is sufficiently disintegrable to permit convenient disposal of a used wipe by flushing down a toilet without harm to any part of the toilet system, a septic tank. The paper substrate should be capable of absorbing an amount of water sufficient to result in dissolution of a major amount of the active agents present C -7in the wipe in order to facilitate transfer of effective amounts of the active agents from the wipe to the surface being cleaned and disinfected.

Quaternary Amnmonium Compound The quaternary ammonium compound employed can be selected from any of the well known classes of antimicrobial, water-soluble quaternary ammnonium compounds. Such classes include the quaternary heteronium compounds such as cetyl pyridinium chloride, polymeric quaternary ammnonium compounds such as those described in U.S. Patents 4,506,081 and 4,532,128, and quaternary ammonium compounds of the general formula: FlR2 IRl-NR 3

X

15 L R4I wherein Rl and R 2 are selected from an alkyl group, an alkyl ether group and a hydroxyalkyl group each containing from 1 to 3 carbon atomis, R 3 is an alkyl group containing from 6 to 20 carbon atoms, and R 4 is selected from an alky.

group containing 6 to 20 carbon atoms, an aralkyl group wherein alkyl contains 1 to 2 carbon atoms and heterocyclic radicals, and X- is a suitable anion such as halide, e.g., chloride, bromide and iodide, nitrate, methosulfate and acetate.

Among the quaternary ammonium compounds of the above-indicated general formula there may be specifically ft t t 2tt t Lg 4 *0 0 0 404 0 0 440000 0 0 -8mentioned the C 8 18 alkyl dimethyl benzyl ammonium chlorides and the C8_ 1 8 alkyl dimethyl ethylbenzyl ammonium chlorides and mixtures thereof.

The amount of quaternary ammonium compound employed is critical and should be from about 0.03g to about 0.45g per square foot of the paper substrate. The specific amounts of a particular quaternary ammonium compound which may be employed within this range will depend on such factors as the antimicrobial strength thereof and substantivity 10 thereof to the paper substrate as can be readily determined 'by one of ordinary skill in the art.

Nonionic Surface Active Agent Any of the well known classes of water-soluble Fi nonionic surface active agents can be employed in the dry s 15 wipe of the invention.

Suitable nonionic surface active agents include those selected from: the polyethylene oxide condensates of alkyl and dialkyl phenols, having a straight or branched alkyl 20 of from about 6 to about 12 carbon atoms, with ethylene oxide wherein the amount of ethylene oxide present is from about 3 to about 25 moles per mole of alkyl phenol; the condensation products of aliphatic alcohols with ethylene oxide of the formula RO(C2H 4 0)nH wherein R is straight or branched alkyl having from about 8 to about 22 carbon atoms and n is 3 to 40; and it'.

-9polyoxyethylene polyoxypropylene block polymers.

Nonionic surfactants of type above are marketed by GAF Corporation under the trademark Igepal®, Igepal® CA-420, an octylphenol condensed with an average of 3 moles of ethylene oxide, and by Rohm and Haas under the trademark Triton®, Triton® X-100, an octylphenol condensed with an average of 9 moles of ethylene oxide.

Nonionic surfactants of type above are marketed by Shell Chemical Company under the trademark Neodol®, S" Neodol® 23-6.5, the condensation product of C 1 2- 13 linear primary alcohol with an average of 7 moles of ethylene oxide, and Neodol 91-8, the condensation product of C9_ 11 linear primary alcohol with an average of 8 moles of ethylene oxide, and by Union Carbide Corporation under the trademark 2' Tergitol®, Tergitol® 15-S-9, a polyethylene glycol ether of a mixture of synthetic Cll-1 5 fatty alcohols with an average of nine moles of ethylene oxide.

Nonionic surfactants of type above are marketed by BASF Wyandotte Corporation under the trademark Pluronic®, Pluronic® 10 R5 which conforms to the formula HO(CHCH 3 CH20)x(CH2CH 2 0)y(CHCH3CH 2 0)zH in which the average values of x, y and z are respectively 7, 22 and 7.

Nonionic fluorosurfactants can also be employed in the invention such as those marketed by E.I. Dupont de Nemours and Company under the trademark Zonyl®, e.g., Zonyl® FSN.

_~I

The amount of nonionic surface active agent employed also is critical and should be from about 0.002g to about 0.03g per square foot of the paper substrate. The specific amount of a particular surface active agent which can be employed within this range will depend on its detergent power as can be readily determined by one of ordinary skill in the art.

t The dry wipe optionally, but preferably contains l t a fragrance for imparting a pleasant odor to the cleaned tssurface. As used herein, the term "fragrance" includes 1 dj 0 chemicals which can mask malodors and/or destroy malodors.

SF When employed, the fragrance is present in the dry wipe up to about 0.3g per square foot.

I er Other optional ingredients also .iay be included .iI P in the dry wipe in small amounts in order to provide additional benefits. Such ingredients include antistatic agents for dust control and anti-fogging agents and can be included q oup to about 0.03g per square foot of paper substrate, The dry wipe can be prepared by uniformly applying a solution or dispersion in a volatile liquid of the quaternary ammonium compound and the nonionic surface active agent, and any optional ingredients, if desired, to the paper substrate and then allowing the treated paper substrate to air dry either at room temperature or elevated temperatures which are not detrimental to the paper substrate or ingredients incorporated therein. The solution may be -11applied by any of the known processes such as immersion of the substrate in the solution, spraying the solution onto the substrate or coating the substrate by means of a suitable applicator. Because of the relatively small amounts of the active agents which in accordance with the invention must be uniformly distributed to the paper substrate, a particularly advantageous and preferred process is one in which a printing technique using a precision engraved roll is employed, such as that described in U.S.

Patent 3,786,615, incorporated herein by reference. Brieflyo in that method a strip of paper to be coated is brought into contact under pressure with a precision engraved applicator suitable for gravure printing which delivers a precisely calculated amount of the solution to the paper strip.

The treated sheet then is allowed to dry.

Any volatile liquid in which the ingredients to be applied are readily soluble or dispersible and which is compatible with such ingredients and the paper substrate can be used to prepare the solution or dispersion. Particularly useful are water and alcohols, ethyl alcohol, and mixtures thereof. The ingredients can be applied to the paper substrate in one step from the same solution or sequentially in separate steps from different solutions.

-12- The dried treated paper substrate can be converted to any convenient form for use by the consumer. It can be embossed, slit, cut and folded into appropriate configurations for packaging. Thus it may be packaged in individual towelette form orwell known bulk towelette form from which individual towelettes can be dispensed such as a web of the dry treated paper substrate of suitable width and perforated transversely such as to readily permit sequential 0000 o 00.0 detachment of single towelettes.

0000oooo 10 The dry wipes may be packaged for use by any 0 0000oooo o 0 0 of a number of well known methods. As will be appreciated, a°o because the wipes are dry, moisture impervious packaging 0 Du material is not required although, in some circumstances, 0°C' such packaging material may be indicated, in hot 0 00 o 0o 15 humid climates where the dry wipe might absorb an undesirable 00 amount of moisture from the atmosphere.

C,

ooa The dry wipe is activated for use by wetting the wipe with water up to the limit of its water-absorbancy.

0 000000 oooeoo S0 Disinfection and cleaning of a surface is accomplished by rubbing the moistened wipe over the surface using sufficient hand pressure to express most of the absorbed water carrying effective amounts of the active agents onto the surface and allowing the cleaned surface to dry during which time disinfection proceeds to completion. The used wipe is then disposed of and no further cleaning steps such as rinsing and drying with a cloth or paper towel -13are required because by virtue of the critical amounts of the active agents employed in the dry wipe, as described hereinbefore, substantially no unsightly streaking, smearing j or spotting will occur.
