DESCRIPTION:
BRIEF SUMMARY
This application is a national phase application of International Application No. PCT/FR95/01573 filed Nov. 29, 1995.
The present invention relates to a disinfectant or antiseptic composition based on terpene alcohol and possessing broad-spectrum bactericidal activity, that is to say activity both on gram-positive and gram-negative bacteria.
The present invention relates to the bactericidal properties of terpene alcohols, in particular those present in essential oils or pine oil.
Pine oils consist of mixtures of terpene hydrocarbons and alcohols. In these mixtures, the proportions of terpene hydrocarbons and alcohols may be in a ratio of from 20/80 to 95/5, preferably 50/50 to 95/5. The terpene alcohols are essentially composed of monocyclic terpene alcohols (terpineols, terpin-1-en- 4-ol, etc.) and, in lower proportion, tricyclic terpene alcohols (fenchol, borneol, etc.).
Pine oil is known and used for its bactericidal properties in disinfectant compositions, in cleansing and disinfectant compositions and in antiseptic compositions. However, the bactericidal activity of such compositions is limited to gram-negative bacteria.
The reason for this is that terpene alcohols, in particular those of pine oil, in solution, in microemulsion or in aqueous dispersion, are not effective on gram-positive microorganisms, at the very least not in the forms currently available.
In order to obtain a disinfectant or antiseptic which has a broad spectrum of antibacterial efficacy, one or more compounds having bactericidal activity against gram-positive microorganisms thus have to be used in combination with the pine oil.
In a conventional manner, these bactericidal active materials are selected from quaternary ammoniums, phenol derivatives, aldehydes, etc. However, these compounds have the major drawback of being too dangerous at certain concentrations and are thus not sufficiently harmless towards the user.
To prepare disinfectant or antiseptic compositions with broad-spectrum efficacy which do not use such compounds, it would appear to be advantageous to study other combinations with terpene alcohols which afford the same properties.
The present inventors have discovered that the combination of certain surfactants, which themselves have bactericidal properties against gram-positive and gram-negative microorganisms, with a terpene alcohol makes it possible to achieve this aim in a noteworthy manner.
The subject of the present invention is thus a disinfectant or antiseptic composition which possesses bactericidal activity both on gram-positive and gram-negative bacteria, this composition containing no quaternary ammonium and comprising (i) at least one terpene alcohol and (ii) at least one bactericidal acidic surfactant such as, in particular, an alkyl polyether carboxylic acid, an alkenyl polyether carboxylic acid, an alkylaryl polyether carboxylic acid or a phosphoric ester of an alkoxylated nonionic surfactant, in acidic or partially neutralized form.
The present invention also provides broad-spectrum bactericidal, disinfectant, cleansing compositions comprising the ingredients mentioned above.
The composition according to the invention may advantageously comprise (i) a mixture of terpene alcohols containing, in particular, 30 to 100% by weight of monocyclic terpene alcohols, preferably 80 to 95%. It may in particular comprise a mixture containing 70 to 100% by weight of terpineols, preferably 80 to 90%.
The composition may also advantageously comprise (i) a mixture comprising at least one terpene alcohol and at least one terpene hydrocarbon.
Preferably, the weight proportions of terpene alcohol(s) and terpene hydrocarbon(s) are in a ratio of from 20/80 to 95/5, in particular 50/50 to 95/5.
In this case, pine oil may be used as mixture (i). The latter may be of natural or synthetic origin, obtained, for example, by catalytic hydration of .alpha.-pinene.
The other important component of the composition according to the invention is a bactericidal acidic surfactant (ii).
When the acidic surfactant (ii) is of alkyl, alkenyl
