Description
United States 3,063,895 DISINFECTANT COMPOSITIGNS- Charles Arthur Pearson and James William Gibson, Hull. England, and Wilhelm Barthels, Hamburg, Germany, assignors' to William Pearson Limited, London, England, a British company No Drawing. Filed Jan. 25, 196i Ser. No. 4,170 Claims priority, application Great Britain Jan. 29, W59 2 9 Claims. c1. 167--3l) This invention is concerned with improvements in or relating to disinfectant compositions.
Many disinfectant compositions are now well-known, the great majority of which are aqueous solutions or emulsions of phenolic compounds. However, known disinfectants suffer from a variety of drawbacks, among which may be mentioned selective action against only certain organisms, reduction in efficiency by organic matter or some specific inhibitor, high tom'city, corrosive action on the skin or mucous membrane, production of scum when diluted in hard or brackish waters or reduction of efficiency therein and immiscibility with sea water.
It is an object of the present invention to provide a new and improved disinfectant composition.
The disinfectant compositions according to the invention are aqueous solutions essentially containing the following phenols in the proportions by weight stated:
Percent p-Chlor-m-cresol 1-6 The compositions according to the invention further preferable contain alkali-metal or ammonium ions to increase the solubility of the phenols present. The pH of the compositions preferably does not exceed 11. A convenient quantity of alkali metal (preferably sodium) or ammonium ions is from 02-29% by weight (calculated as alkali metal or ammonium hydroxide).
A preferred composition according to the invention comprises an aqueous solution, having a phenol content equivalent to 16% of p-chlor-m-cresol, 0.55% of ophenyl phenol, 0.55% of an alkali metal salt, preferably sodium salt of o-phenyl phenol, 0.55% of o-benzyl-pchlorphenol and from 15% of an alkali metal salt, preferably sodium salt of a polychlorphenol.
We have found that the compositions according to the inventionhave a range of action against gram positive and gram negative bacteria, fungi and fungal and bacterial spores substantially greater than disinfectant compositions hitherto proposed. Thus, known disinfectant compositions, whilst active against certain organisms, have failed against other important organisms. The compositions according to the invention have, however, been found to be very effective against most, if not all, of the micro-orgam isms which it is desired to combat, for example, in hospitals. In particular, the compositions according to the invention, besides being active against such common organisms as Staphylococcus aureus, Streptococcus pyo genes and Pseudomorms pyocyaneus, are highly effective against Mycobacterium tuberculosis and various sporulating organisms as well as many pathogenic fungi. tshould ice be pointed out that, in the compositions according to the invention, both the nature of the phenolic ingredients used different proportions do not possess the same wide range of action as do the compositions according to the invention. The compositions according to the invention are'also generally effective in the presence of various kinds of organic matter.
The compositions according to the invention preferably also contain from '0.55% of p-chlor-m-xylenol, which component has been found to enhance the biocidal-activity of the composition, particularly against gram negative bacteria.
The compositions according to the invention further preferably contain a water-miscible (or partially watermiscible) alcohol for the purpose of further aiding the solubility of the phenols thereby reducing risk of precipitation on dilution with, for example, hard or brackish water. Alcohols containing from 1-4 carbon atoms are very satisfactory, examples of which are methanol, ethanol, propanol, iso-propanol, iso-butanol, etc; a concentration of from 5-25 of alcohol has been found to be advantageous.
The compositions according to the invention further preferably contain a compatible surface. active agent. Anionic surface active agents are particularly useful and examples of such substances are alkyl sulphate salts, such as sodium lauryl sulphate, mixed alkyl aryl sulphatesalts and various sulphonated oils, e.g. sulphonated castor oil. The detergents sold as Teepol, Comprox and Iranapol have been found to be very satisfactory.
The preferred polychlorphenols for use in the compositions according to the invention are tri-, tetraand pentachlorphenol.
The compositions according to the invention may be formulated in any convenient way. Thus, for example, the parent phenols may be conveniently mixed with water, alcohol and surface active agent, and the necessary quantity of alkali metal or ammonium hydroxide may be added to give the desired proportion of alkali metal or ammonium ions. Alternatively one or more of the phenols may be added as their salts.
Particularly useful compositions according to the invention are those equivalent to the following composition.
Sodium pentachlorphenatel5%. C C alcohols 525%. Surface active agent l040%. Water To%,
An example of a formulation according to the invention which has proved especially effective is given as follows, for the purpose of illustration only.
4% p-chlor-m-cresol 1.5% o-phenyl phenol 1.5% sodium o-phen-ylphenolate 1% o-benzyl-p-chlorphenol 1% p-chlor-m-xylenol 3% sodium pentachlorphenate 10% iso-propanol 28% Teepol 514 Water to 100% The composition according to the above-mentioned example has the following properties:
It is a clear amber fluid, stable to both heat and cold. Refluxing at 100 C. for 4 hours does not destroy its germicidal activity, whilst, if held at C. for several weeks, it does not crystallise out or deposit.
It is only mildly alkaline, 1%, 2% and dilutions in tap water having pH values of 8.2, 8.4 and 8.6 respectively.
In the recommended dilutions, it is non-corrosive to skin at 1% and mucous membrane at 0.5% as evidenced by its successful application in cases of acute vulvo vaginitis.
All dilutions in distilled or hard water are crystal clear to slightly opalcscent, and free from deposit or scum, an advantage particularly applicable to instrument sterilisation. It is miscible with sea and brackish waters. forming clear to opalescent solutions. Germicidal tests were carried out upon the composition according to the abovementioned example with the following results:
Germicidal Test Results Using E. coli, Ps. pyocyaneus, Proteus vulgaris and S. aureus in a series of suspension tests conducted at 18 C., a 0.5 soln. of the composition in hard water killed all the test organisms in less than 2 /2 mins. Similar tests performed in the presence of 20% blood serum, 20% skimmed milk or 1% linseed oil soap soln. again showed complete destruction of the organisms by a 2% dilution in less than 2 /2 mins.
Linen strips infected with the dried test organisms are sterilised in 30 mins. at 18 C. by a 3% soln. of the composition, even in the presence of 1% linseed oil soap soln.
Fungicidal properties are demonstrated by the destruction of Trich. inderdigitale, Trich. acumz'naziwn and Candida albicans in 30 mins. by a 2% soln. of the composition at 18 C.
Against Trichomonas vaginalis, a solution of 1 part of the composition of the example in 700 parts of water destroyed the parasite, in organic medium, within 5 minutes at 36.
Comparative Results For comparison several well-known types of disinfectant were tested; these were Liquor chlorxylenolis B.P. (L.C.X.), Liquor cresolis saponatus B.P. (L.C.S.) and a disinfectant of the coal tar-oil type according to British Standard Specification No. 2462.
The results obtained compared with the composition of the above example show the advantages of the latter in germicidal eiiiciency.
Tests were performed in distilled water (W) and blood serum (S) by the Rideal-Walker (R.W.) (B.S.S. 541:1934) and Food and Drug Administration of the United States (F.D.A.) methods.
