Description
United States Patent Ofi" 3,2216% Patented Jan. 4, 1966 3,227,614 GERNHCIDAL PAPER Fred F. Scheuer, Bronx, N.Y., assignor to Dustllrin Pro-d- ;ctsii Inc., New York, N.Y., a corpuration of New No Drawing. Filed Sept. 29, 1960, Ser. No. 59,150
13 Claims. (Cl. 1167-84) This invention relates to a bacteriostatic or germicidal paper or tissue. More particularly, it relates to a germicidal or bacteriostatic paper or tissue which may be used wet or dry to wipe surfaces to render them germicidal or bacteriostatic.
} It is an object of the present invention to provide a germicidal or bacteriostatic paper which is disposable, economical and effective in rendering surfaces bacteriostatic or germicidal when contacted with this paper. (This is to be contrasted with the common use of untreated paper which may be already contaminated with pathogenic organisms and which transmits these organisms to asurface to be cleaned.)
It is a further object of the present invention to provide a method for preparing such paper.
Other and more detailed objects will be apparent from the following description and claims.
The inexpensive, disposable bacteriostatic paper or tissue of the present invention is of great value both for civilian and military uses.
Dry it is useful in hospitals, doctors offices, laboratories, etc. as dust Wipers, which impart the areas wiped with potential bacteriostatic protection. In this manner the danger of the spread of dust-born infection in hospitals and doctors offices can be reduced. Another use is wiping telephone receivers, keys of typewriters and electronic equipment, industrial safety equipment such as the exposed surfaces of gas masks, goggles, welders and riveters safety masks, respirators, inhalators, safety shoes and boots, etc. in order to render them sanitary.
Wet it is useful in hospitals, doctors ofiices, laboratories and all places where antibiotic protection is required. By simply putting as much water on the paper as can be absorbed, a solution with high bactericidal activity as well as detergent value is instantly produced without the need for measuring water or germicide; There is also no need to wash and rinse the object to be cleaned before using a germicide. For example, an operating table, a toilet seat, etc. can be cleaned and sanitized in one single operation. A soldier, a nurse, a stewardess, etc. can carry a germicide in the pocket in dry form. A two ply wiper size 13" X 18" which weighs only about 7 gms. will absorb about one ounce of water to produce about one ounce of bactericidal solution combined with an efiective alcohol type detergent and provide means of applying a cleaner and sanitizer in one operation.
In the manufacture of germicidal dustcloths made of cotton and the like it has been customary to impregnate the cloth with an aqueous solution containing a germicide which is then air-dried on the colth. Because of the nature of the structure of the cloth it could be subjected to treatment with the aqueous solution for long periods of time without deleterious effect. In attempting to apply these aqueous processes to the treatment of paper it was soon found that the results were not satisfactory. It was found that from an aqueous solution of germicide the paper could not absorb more than 1% water without altering its structure. The absorption of this small amount of water would not result in the deposition of adequate amounts of germicide on the paper. It was thus necessarytodevise a'methodto deposit an adequate amount of germicide on the paper.
It has now been found that paper will absorb sufficient germicide to render it useful as a germicidal or bacteriostatic paper without altering the structure of the paper if the paper is treated with a non-aqueous vehicle in which the germicide is distributed.
A variety of non-aqueous liquid vehicles are known which are useful for the purpose of the present invention. Among these may be mentioned light oils, hydrocarbon distillates, solvents, monohydric alcohols, glycols, naphthas. The preferred liquid vehicles are the normally liquid hydrocarbons, cg. normally light liquid hydrocarbon oils, aliphatic naphthas, Stoddard solvents, kerosenes (refined), paraffinic hydrocarbons, natural mineral oil, pine oil, white mineral oil, etc.
Since the products of the present invention generally come in contact with the skin, the non-aqueous liquid vehicles generally employed are those that are non-toxic or non-irritating when the paper contacts the skin. Furthermore, the said vehicle obviously should be of such a character as not to deleteriously affect the bacteriostatic or germicidal properties of the anti-bacterial agent employed.
All of the ingredients are preferably completely disper sible in the non-aqueous vehicle so that subsequent agitation is not needed to redisperse the ingredients in the vehicle before use. By using the proper percentage of liquid vehicle a total all-side surface treatment is assured. This is especially important when tissue paper is being used which comes in 1, 2, 3, 4-ply or more.
For some purposes it is advantageous to incorporate in the paper certain agents. Thus, for example, there may be added to the liquid vehicle a silicone, wax or other agent which will be adsorbed on the paper when the paper is processed in accordance with this invention.
The germicidal and bacteriostatic agents which are preferably selected for the use in the present invention are the quaternary ammonium compounds which fulfill the requirements of stability, substantivity and low degree of toxity. Of particular interest are the quaternary ammonium compounds of the following general structure wherein R R R and R are selected from the class consisting of alkyl, aryl, aralkyl and heterocyclic radicals and X is a halogen. Of special interest are the alkyl dimethyl benzyl ammonium chloride compounds. The alkyl group in these compounds may be lower or higher alkyl groups.
A variety of water soluble germicidal or bacteriostatic chemicals are known in the prior art which may be used in the present invention. Among these may be mentioned:
(27) (fl-Phenoxyethyl) dimethyl dodecyl ammonium H bromide (28) Octyl phenoxy ethoxy ethyl dimethyl p-chlorobenzyl ammonium chloride (29) Dialkyl dimethyl ammonium chloride (30) Dialkyl dimethyl ammonium bromide (31) Decamethylene-bis (decyl dimethyl ammonium) bromide (32) Trialkyl benzyl ammonium chloride (33) Myristamido propyldimethyl benzyl ammonium chloride (34) Myristyl-Y-picolinium chloride (35 N-N-N-N'-tetramethyl-N-N-didodecyl-fl-hydroxypropylene diammonium bromide With the present invention waxes, high percentage pine alcohols, oils and/or silicones can be added to the required degree and the resulting admixture remains clear indefinitely without separation. This will permit the production of bacteriostatic paper for the many different purposes intended in the invention.
A feature of the present invention is the fact that no separation of the essential constituents of the treating composition occurs. This is true of the treating solution before it is applied to the paper or tissue as well as the treating composition disposed on the paper or tissue. Since the treatment of the paper in accordance with the present invention may involve contacting the paper with a treating solution for several days, it is very important that the components of the treating solution do not separate out. Furthermore, since it may take several days for the treating fluid to reach the deeper plies of paper, it is essential for the proper treatment of these deeper plies that the constituents of the treating solution do not separate out.
This property of stability of the present treating compositions is greatly enhanced by incorporating in the treating solution a detergent of general formula 11 amon -omega wherein R is preferably a long chain alkyl radical and x has an average value of from 10 to 20. The best results are obtained with compounds of Formula 11 above wherein R is a saturated highly branched chain alkyl group of from 11 to 15 carbon atoms and particularly with the polyoxyethylene ethers of tridecyl alcohols. By way of illus tration the following compounds which are useful in the present invention may be mentioned: polyoxyethylene ether of tridecyl alcohol containing 12 oxyethylene groups per mole; polyoxyethylene ether of tetradecyl alcohol containing 16 oxyethylene groups per mole; and polyoxyethylene ether of pentadecyl alcohol containing 14 oxyethylene groups per mole.
The relative proportions of germicide to the other ingredients contained in the treating solution may be varied considerably without departing from the spirit of this invention. In the preferred practice of the invention the ratio of germicide to the weight of treated paper will vary in the range of from 0.3 to 0.6 part by weight of germicide to the treated paper. When a detergent is employed, it is preferably used in the range of l to 5 parts by weight of the liquid vehicle. The other agents, e.g. silicones, oils, waxes or other polishing agents which are employed, are preferably used in the range of about 1 to 5 parts by weight of liquid vehicle.
The following examples are further illustrative of the present invention. It is to be understood, however, that this invention is not limited thereto.
EXAMPLE 1 7 One part by weight of alkyl dimethyl benzyl ammonium chloride in water is mixed with 4 parts by weight of 100% polyoxyethylene tridecyl ether alcohol to form a 10% solution of said alkyl dimethyl benzyl ammonium chloride. This solution is further used to prepare the treating solution. The percentages of the materials indicated below in this example are based on the total weight of the treated paper product made in accordance with the present invention. Three percent of said 10% solution of quaternary ammonium compound was mixed with a solution containing 17% hydrocarbon distillateand 1% silicones. This solution is used in test A below.
EXAMPLE 2 A solution was prepared by diluting one part of a 50% solution of alkyl dimethyl benzyl ammonium chloride in water with 2 parts by weight of 100% polyoxyethylene tridecyl ether alcohol 2 and 2 parts by weight of pine oil containing terpene alcohol to form a 10% solution of said alkyl dimethyl benzyl ammonium chloride. The percentages of materials indicated below in this example are based on the total weight of the treated paper product made in accordance with this invention. Three percent of the 10% solution of quaternary ammonium compound prepared above was mixed with 17% of hydrocarbon distillate and 1% silicones. his solution is used in test B below.
EXAMPLE 3 Three percent of the 10% solution of said quaternary ammonium compound prepared in Example 2 was mixed with a solution containing 5% carnauba wax, 12% hydrocarbon distfllate and 1% silicones. This solution is' used in test C below.
