Description
3~
The invention concerns a disinfecting tissue com-prising an absorbant material and a disinfectant which can be used particularly for disinfecting skin and hands for the preoperative preparation of patients, for disin~ecting surgeons' hands, and in surface disinfection.
The di~infecting agents cutomarily employed in skin and hand d.isinfectlon are mainly aldehyde- or phenol-based mixtures or suitable detergents or soaps contalning such mixtures as well as peracetic acid solutions. 'rhe dis-advankage of these agents reside~ in the known toxic effectssuch as alleryies, skin irritation by alcohol or soap, corrosiveness of the peracetic acld, which tendencies severely limit the application of such preparatlons. Also, in surface disinection the indicated agen~s are not optimal.
Aside from dosage pxoblems ! odorous annoyance and allergic manifesta~ions, the problem o~ the corrosiveness facing the various materials has not yet been solved satisfactorily.
Furthermore, e.g., according to German Patent No.

Also, in surface disinection the indicated agen~s are not optimal.
Aside from dosage pxoblems ! odorous annoyance and allergic manifesta~ions, the problem o~ the corrosiveness facing the various materials has not yet been solved satisfactorily.
Furthermore, e.g., according to German Patent No.
2,~44,265, dispensers for absorptive sheet.ing in the form of a coreless roll, placed in a container, which can be re-moved from an aperture, and where the absorptive material impregnated wi~h alcohol or other liquids can be pulled from the contalner aperture are known.
These containers, however, are relatively bulky and have the disadvantage that the impregnation or disin-fec~ing agents are easily volatilized and display the above men~ioned disadvantages of the known disinfectants.
Tissues which deliver other agents are known, such as, for example, menthol-impregnated paper handkerchiefs or ~3~ 4 silver polishinq cloths impregnated with polishing agent, where the agent is distributed across the whole fiber matrix of the sheeting. These tissues intended for single or multiple application, have the disadvantage that the active S agent can emerge from the sheating or that the tissues libexate dust so that exterior packaging is necessary to insure that the active agent is not los~ from the merchan-dise upon storage. Tissue-like sheeting is known that is soaked with liquid agents or sponge-like struc~u~es into which a plastic ampule with liquid is incorporated. The liquid soaked cloths have the disadvan1:age that they must be covered with an impermeable membrane, mostly of plastic, in order to prevent premature evaporation of the liquid agent. Considerable trouble is required to break the ampules incorporated into $ponge-like structures in order to liberate the active liquid for use.
An object of the present invention is to provide toxicoloyically unobjectionable disinfecting agents for skin, hand, and surEace disinfection in a suitable form for appli-ca~ion. It is deslred that the tissues be impregnated withdisinfectants which can be manufactured in a simple manner, which can be stored without great precaution~, and which are immediately usable.
In accordance with the present invention there is provided a disinfecting ~issue comprising an absorbant mate-rial and a disinfectant, said disinfectant being adapted to be converted into its disinfecting form upon moistening with w~ter.
The absorbant material or carrier can be formed of natural, synthetic or mixed textile materials, of textile or cellulose fiber fleece, or sui.table paper. Size and ~orm depend on the respective end use. The carrier can have the form of a single tissue or of an endless, tearable sheet or ribbon, rolled and/or folded, packaged singly or in larger containers, preferably provided in a tearable or rollable array.
The porous water-permeable sheeting material, where ~3~Z04 the disinfecting material is positioned between its layers, is prefPrably a tangled fiber fleece on a cQllulose or poly-mer base, as for example, a polypropyl~ne tangled fiber fleece. Of impor~ance is only that the effective pore size of the sheeting is smaller than tha particle size o the disinfecting agent. The term effective pore size means ~he available aper~ure perpendicular to the ma~erial layer which separates the disinfecting agent from the outer atmosphere.
For example, the effective pore size in a ~angled iber fleece is considerablv smaller than the pore size of the tanyled flber fleece on the surface of the sheeting. It is of the order of magnitude of a few ~ to 150 ~.
In the tissues according ko the invention, the disinfecting agent is practically fixed in one or several cavities or pockets between at least two laye~s of the sheeting, whereby the cavities containing the disinfectant are sealed so tha~ the disinfectant cannot emerge from the margin o the tissue. Preferably, if several cavities or pockets are provided in the tissue to receive the disinfect-ank, ~hese separate cavities are more or less sealed ~romeach other.
The sealing of the margin areas can be carried out with pressure, for example by lamination or pressure sealing, or also by glueing them together. For example, the sealing can be carried out by a heat sealable plastic.
The manufacture of such tissues can be carried out in a simple manner utilizin~ conventional equipment. For example, the disinfecting agent is applied in portions on one sheet, which then is covered with a cover layer or a second layer o the sheeting and subsequently $ealed with the lower layer. This can be carried out by passing the layered structu~e with the interspersed disinfecting agent ~hrough calender rollers which effect the sealing of the two layers. The sheeting can subsequently be divided into smaller segments, provided, however, that ~he cavities co~-taining the disinfecting agent remain in~act by this sepa-ration. It is also posslble to employ sheeting onto which ~3~)204~
before, during or after addition of the portions of active material, a plastic adhesive strip has been applied whereby heat-sealable polyethylene adhesives are particularly suit-able. The shee~ing, after application of the second }ayer, is passed through a calender roller which presses and thereby seals the adhesive strips with mild heat appliaation.

Particularly sui~able laundry raw materials are among others fatty acid soaps, alkylbenzenesulfonates, lauryl sulates, oleinsulfon-ates, secondary alkylsulfonates, alkylphenylpolyglycol ethers, polyoxypropylene glycols, amine oxides and betaines.
Advantageous, furthermore, i~ the simultaneous use oE water-binding agen~s. Example.s of suitable waker-binding agents are, e.g., calcium chloride, calcium oxide, potassium carbonate, magnesium perchlorate, magnesium sulate and sodium sulfate.
Aside from the organic peroxides, the O-acyl or N-acyl compounds, respectively, the H2O2 donors, the protectlng covering agen~s, the water-binding agents and fillers, the h~3VZ04 , ., cloths can addl~ionally contain stabilizers for the peracid and/or H2O2, pH-adjus~ing and s~abilizing agents, corrosion inhibitors, perfume~, further antimicrobial su~stances and dermatologically important additives.
Suitable stabilizing agents for H2O2 and/or the peracids are, e.g., urea, alkali salts of metaphosphates, alkali salts o polyphosphates, 2,3-pyridine-dicarboxylic acid, 2,6-pyridine-dicarboxylic acid/ citric acid and their alkali salts, ethylene-diaminetetraacetiC acid and it5 alkali salts, and nitrilo~tri]acetic acid as well as its alkali salts. The stabilizers may be present in an amount of 0.01 to 5~, preferably 0.1 to 5%.
Corrosion inhibitors are benzo~riazole, alkali phosphate, alkyl phosphate and aminoxide. Their respectivç
amountS are 0.01 to 10%, preferably 0.5 to 5%.
As antimicrobial additives, for example, sorbic acid, ben~oic acid and salicylic acid may be employed. For adjusting and stabilizing the pH value citric acid and its sal~s, alkali phosphates, alkali acetates, lactic aci~ and its alkali salts, alkali bisulfates, alkali carbonates and alkali bicarbonates may be employed.
The pH value of aqueous solutions of the dislnfect-ing cloths according to ~he invention is 3 to 12, preferably 4.5 to 11, and specifically 6 to 9.
Dermatological skin care additives such as, e.g., biotin, amino acids, polysaccharides, invert sugar, urea, allantoin and borax may be present in the cloths, The microbiological activity of the disin~ecting cloths according to the invention was determined according to the DGHM method for hygienic, or surgical, respectively, hand disinfec~ion. The disinfection cloths for surface dis-infection were tested undex the conditions of the suspension test and the surface test according to DGHM .

All disinfec~ing tissues according to the inven-tion which have disinfectants applied on the surface or in-corporated in some other manner into the cloth develop an~imicrobial efficacy practically instantaneously and could be easily and practically utilized.
The dry disinfection mixture can be physically in-corporat~d into the cloth in several ways, e.g.,~by impreg-nation or by matting of granular or powdered mixture withthe fibers of the absorptive material or by chemical bonding, e.g., by acylation of the absorptive material with the ~3CJ 204 ^ . ~

carboxylic acid chlorides or anhydrides according to the invention.
In the following, a model of the disinfecting tissue according to the invenkion will be further illustrated by drawings:
Figure 1 shows a top view of the tissue acGording to the invention;
Figure 2 is a perpendicular crosS-section along the line A-A of the tissue shown in Figure l;
Figure 3 is a top view of a ~urther specimen of a tissue accordin~ to the invention;
Figure 4 is a top view of the tissue according to the invention, where the covering layer has been removed; and Figure 5 is a cross-section along line B-B of the tissue illus~rated in E'igure 4.
The tissue shown in Figures 1 and 2 consists o two layers of a tangled fiber fleece wi~h a thickness o~ 0.15 to 0.2 mm and a layer weight of 42 g./m.2. This tissue has dimensions of ca. 6 x 6 cm pressure sealed at the marginal area 4, so tha~ the ~wo layers 2 and 2' canno~ separate from each other. The seal effected at the margin 4 forms a chamber or pocket 6, between layers 2 and 2', in which the disinfecting agent is contained.
In the embodimen~ depicted in Figure 3, the actlve agent is disposed in several compartments between individual layers~ These several chambers or pockets are achieved by a rhomboid stamping 4', yielding a multiplicity of pockets 6l, 6". This method of preparation has the advantage over the embodiment oE Figure 1, in that the disinfecting agent is mo~e uniformly d~stributed over the tissue and does not accumulate as a mass at the bottom of the tissue on vertical storage of such tissues as is the case with a kissue having a single pocket.
In the embod~n~ shcwn in Figures 5 and 6, the apertures for receiving the active agent are in the form of small pockets, for~ed for example, by compressing the sheeting.
