Abstract
A composition designed to disinfect surfaces by aerosol dispersion in surrounding air contains, as active components, firstly a methyl-isopropylphenol (e.g. thymol) and secondly a glycol alkyl ether (e.g. ethylene glycol monobutyl ether), dissolved in water.
Description
SPECIFICATION
Disinfectant Compositions
This invention concerns new compositions designed to be used to disinfect surfaces by air method.
Such compositions are known, as to their principle, and used at present in various aerosol generator appliances such as those described by the Applicant in his French Patents 1.568.295, 75.02188,75.18474, 76.36270 and 77.12479.
Until now compositions of this type basically contain formol as active component, the other components in the compositions only playing a secondary part, their proportion being insufficient for them to exercise any specific action, at least to any appreciable degree.
The recent developments of studies on the dangers offered by formol in various medical areas have incited the Applicant to seek a new composition in which formol no longer figured, but which would nevertheless exercise a satisfactory disinfecting action, if not even better.
The Applicant's research has therefore led him to the surprising observation that this result could be obtained via the combination, in given proportions of several components, themselves known, but which do not possess individually the qualities required for this use.
The first embodiment of the composition according to the invention is selected from the class of methyl-isopropylphenols, such as 5-methyl-2-isopropyl-phenol, or m-thymol, 2-methyl-5-isopropyl-phenol, or carvacrol (or isothymol), or their chlorine derivatives. The preferred member of this group is the m4hymol, and in the rest of this text it will be referred to under the name of "thymol".
The second embodiment of the composition according to the invention is selected from the class of glycol alkyl ethers, such as the monobutyl ether of ethylene glycol or the diethylene glycol ethyl ether. The preferred member of this group is the ethylene glycol monobutyl ether, well known under the trade name of "Butyl Cellosolve" and which will be referred to in the rest of this text under the simplified name of "butyl glycol".
The third embodiment of the compositions according to the invention is water.
If we now consider each of these three components, the following observations can be made:
Thymol has been known for a long time amongst products of a natural origin as cleaning agent, for its destructive action on fungus and vegetable parasites. In this respect it has been proposed by chemists as ointment and in an alcoholic solution as contact disinfectant. Owing to the fact that it is not water-soluble, no preparation designed for disinfection by air method only containing thymol as basic ingredient has been proposed until now.
Butyl glycol is also known, but only as solvent without any bactericidal action having been indicated. Its role in the compositions according to the invention is a multiple one: - In the first place it has the effect of solubilizing thymol.
- In the second place experience has shown that it itself shows a certain bactericidal action, but fairly low.
- In the third place experience shows surprisingly that this bactericidal action is notably increased by the
presence of thymol.
Finally water is indispensable for the compositions according to the invention, to enable the aerosol formation appliance to diffuse the solution, in the form of sufficiently fine particles to deposit extremely slowly, notably on the upper parts of partitions, and to cross through porous obstacles, such as blankets.
The presence of the right portion of water ensures the provision, in the room to be disinfected, of the rate of relative humidity most favorable to the disinfecting action, of around at least 6070% at 20"C.
The relative proportions of the three components in the compositions according to the invention are defined by the respective part played by the said components: Thymol becomes ineffective below 01 % in weight, and makes the atmosphere difficult to breathe
around 5%. In practice its optimum proportion is around 0.75 to 1%.
butyl glycol does not assume its solubilizing role any longer below about 5%, and exercises
unacceptable stripping action beyond 30%. In practice its optimum proportion is around 20%.
water normally makes up the restto 100%.
- Finally, according to an alternative version coming within the scope of the invention, a part of the butyl
glycol can be replaced by 2-methyl-2,4-pentane-diol (or hexylene glycol), acting both as co-solvent and
stabilizing agent.
To take a nonexhaustive example, a composition entering into the scope of the invention will contain, in percentage of weight:
Thymol 0.75
Butyl glycol 20
Hexylene Glycol 8
Water (demineralized) 71.25
This composition is obtained by cold dissolving thymol in butyl glycol then, after adding the hexylene glycol, entering the water and stirring. A colorless slightly opalescent liquid is obtained, density d,,.=0.9867--0.9877, refractive index n2OO=1.36601.3670, being preserved without loss of activity for several years.
This composition is used as it is in an aerosol generator as indicated above, with a dose of around 20 ml/m3 of volume of air to be treated, for about 4 hours. An essential advantage of this composition is that the room can be reoccupied after only 30 minutes airing, instead of the well known difficulties which remain after using formol based compositions.
The bactericidal efficiency tests, performed in accordance with French standard T-72-281 on the following microorganisms stocks:
Bacterial Stocks - Streptococcus faecalis CNCM 5855 - Staphylococcus aureus-Oxford Stock CNCM 53/54 - Pseudomonas aeruginosa CNCM A 22 - Escherichia coli CNCM 54127.
Fungus Stock - Penicillium verrucosum Var-Cyclopium CNCM 118679.
Yeast Stock - Candida albicans CNCM 1180--79.
have established a bactericidal action equal to or greater than 5 on the bacterial stocks and yeast stocks and equal to or greater than 4 on the fungus stocks (action expressed in decimal Logs).
The relative humidity of the test room which should be at least 60--70"C at the end of the operation, was obtained by diffusing the product itself, owing to its high water content. Experience has shown that the diffusion of 17 g/m3 of the composition according to the invention increases the relative humidity of a room from 45 to 82%.
As an illustration for the phenomenon of potentialization of the bactericidal action of butyl glycol by thymol, it can be indicated that, in identical experimental conditions (10.7 g/m34 hours contact) a 40% aqueous solution of butyl glycol alone and the composition according to the invention respectively produced the following effects, expressed in decimal Logs: :
Colibacteria Staphylococci Streptococci
Composition according to the invention 5.0 5.0 5.0
Butyl glycol solution alone 1.21 0.33 0.42
These various results clearly show that the compositions according to the invention develop a surface disinfecting action by air method at least as satisfactory as those of the former compositions containing formol, whilst removing their drawbacks, and that this action should be attributed to a potentialization of effects, some of which have moreover not yet been observed owing to their small share in the components of these compositions.
