Description
ORGANIC COMPOSITIONS
The invention relates to antiseptic compositions, and in particular to ready to use antiseptic compositions.
Many compounds suitable for killing or inhibiting the growth of microorganisms are known. Compositions containing such compounds and suitable for application to the human, or animal, body are generally referred to as antiseptics.
Traditionally, antiseptic compositions have been produced, and provided to the public, in concentrated form to be diluted at the time of use. This has a number of drawbacks, including the unavailability of water when antisepsis is required, unclean or contaminated water used for dilution, or inaccurate dilution by the user.
To overcome the above problems the trend has been to produce dilute (or ready to use) antiseptics.
Many of the recent ready-to-use antiseptics are fairly complex, comprising mixtures of antimicrobial compounds, surfactants, solvents etc. However, many of these extra ingredients may be irritating to the skin (eg. alcohols or surfactants) or may interfere with the antiseptic activity of the active agents (eg surfactants).
We have now found that an effective ready to use antiseptic composition may be produced by the combination of a relatively small number of ingredients.
According to the invention, there is therefore provided an aqueous, topical, ready to use, antiseptic composition comprising a) 0.05 to 1% w/v of a biocidal compound of formula I
wherein each R1 is independently selected from hydrogen, a C1.4 alkyl group, a C1.4 alkoxy group, a halogen or a hydroxy group; n is 0 to 3; R2 and R3 are independently selected from C1.4 alkyl groups;
R4 is a C62 alkyl chain (or a mixture thereof), and
X is an anion; b) 0.005 to 0.2 w/v of a chelating agent, and c) 1 to 5% w/v of a polyhydric alcohol;
the composition further comprising substantially no monohydric alcohols.
The monohydric alcohols to be excluded from the compositions of the invention include ethanol and methanol.
Preferably in the compounds of formula I R1 is hydrogen, n is 1 or 2 (most preferably 1), R2 and R3 are each methyl, R4 is an alkyl chain of C818 length (or a mixture thereof) and X is a halogen.
Most preferably, the compound of formula I is a mixture of alkyldimethylbenzyl ammonium chlorides (commercially available as "benzalkonium chloride").
Preferably in the compositions of the invention the concentration of the compound of formula I is from 0.1 to 0.5 w/v, more preferably 0.15 to 0.3t w/v.
Preferably the chelating agents are selected from ethylenediamine tetraacetic acid (EDTA) or a derivative or a salt thereof, or ethylene glycol bis [ss-aminoethyl ether] -N,N,N', N'-tetraacetic acid (EGTA) or a derivative or salt thereof.
More preferably the chelating agent is EDTA or a sodium or potassium salt thereof, or EGTA or a sodium or potassium salt thereof; most preferably it is a sodium salt of EDTA.
Preferably in the compositions of the invention the concentration of the chelating agent is from 0.005 to 0.low w/v, more preferably 0.01 to 0.05% w/v (expressed as the free acid where appropriate)
Preferably the polyhydric alcohol is selected from polyethylene glycols of average molecular weight 200 to 1000 (particularly 200 to 600), propylene glycol, ethylene glycol or mixtures thereof. Most preferably the polyhydric alcohol is propylene glycol.
Preferably the amount of polyhydric alcohol in a composition of the invention is from 2 to 4% w/v, more preferably 2 to 3k w/v.
By topical, ready to use, antiseptic compositions it is meant that the compositions of the invention are suitable (and are intended) to be used directly on the skin of humans or animals without further dilution.
Therefore preferably the compositions of the invention are substantially free of any compound which may cause irritation to the skin.
Preferably the compositions of the invention contain substantially no biocidal phenolic compounds (other than compounds of formula I, where appropriate). More preferably the compositions of the invention are substantially free of any biocidal compounds other than compounds of formula I. For the avoidance of doubt, we do not consider EDTA or EGTA (or salts thereof) to be biocidal compounds.
The compositions of the invention may further contain conventional ingredients of antiseptic compositions, as appropriate. However, it is preferred that the compositions of the invention contain substantially no nonionic surfactants and most preferably they contain substantially no surfactants at all (other than quaternary ammonium biocides of
Formula I)
A preferred extra component in the compositions of the invention is a topical anaesthetic. Most preferably the topical anaesthetic is lignocaine or the hydrochloride salt thereof.
When present, the lignocaine will be present at an amount of from 1 to 5% w/v, more preferably from 2 to 3.5% w/v.
Further according to the invention there is provided an aqueous, topical, ready to use, antiseptic composition comprising a) 0.1 to 0.5 w/v benzalkonium chloride; b) 0.005 to 0.1% w/w EDTA, or a sodium salt thereof; c) 1 to 5% w/v propylene glycol; and d) 0 to 5% w/v (preferably 1 to 5% w/v, more preferably 2 to 3.5% w/v) lignocaine hydrochloride;
the composition further containing substantially no biocidal phenolic compounds (and preferably no further biocides)
and substantially no monohydric alcohols.
Further conventional components include buffering and pH control agents (for example sodium acid phosphate and sodium phosphate), perfumes and colouring agents.
The balance of the compositions of the invention will be water. Preferably the water is softened, distilled or deionised water, most preferably it is softened water.
The compositions of the invention may be produced by any conventional manufacturing process; for example by simply mixing all of the ingredients at room temperature, or whilst heating the mixture, until a solution is formed. The compositions may be produced directly in dilute form or as concentrates to be diluted before packaging.
The compositions of the invention may be packaged in any conventional form. Examples include in sprayable form such as aerosols (also comprising a propellant) or so called pump packs; dispersed onto cloths as antiseptic wipes; in ampoules as single use packs or in conventional (multiple dose) bottles.
The advantages of the compositions of the invention are that they are in a ready to use form, are simple to produce, none irritant and have effective antiseptic properties on the skin.
The invention will now be illustrated by the following examples.

Escherichia coli ATCC 10536, Citrobacter freundii ATCC 8090, Klebsiella pneumoniae ATCC 13883, Proteus mirabilis ATCC 14153 and Pseudomonas aeruginosa ATCC 15442 was assessed in the presence of 1% combined albumin/yeast extract (CAY) . Under the test conditions the maximum concentration of product that can be tested is 80k v/v.
The composition of Example 2 achieved excellent activity, log reductions in excess of 5, against all the challenge organisms, see Table 1.
TABLE 1 : Antibacterial Activity in the presence of 1% organic soil
ME value (after 5 minute contact time) on three consecutive days: Organism Staphylococcus aureus > 6.5 ATCC 6538 > 6.5 5.7 Methicillin Resistant > 3.3 Staphylococcus aureus > 6.3 clinical isolate > 6.3 Enterococcus hirae > 6.4 ATCC 10541 > 6.5 > 6.6 Escherichia coli > 6.5 ATCC 10536 > 6.8 > 6.3 Citrobacter freundii 2.0 ATCC 8090 > 6.8 > 6.1 Klebsiella pneumoniae > 6.8 ATCC 13883 > 6.8 > 6.3 Proteus mirabilis > 6.0 ATCC 14153 4.8 > 6.0 Pseudomonas aeruginosa > 5.9 ATCC 15442 > 6.2 > 6.2 Example 5
The lack of irritancy of the composition of Example 2 was tested by the following procedure.
Twenty-six human volunteers of either sex aged between 18 and 65 took part in the trial. The composition of Example 2 was applied to the skin undiluted. Deionised water and a blank untreated site were included as controls. Each sample was applied to the upper outer arm via an occlusive aluminium Finn chamber which provided a test area of 50 mm2 and a volume of 25 pl. Patches were applied for an initial period of 6 hours, then removed and assessed using a numerical scoring system.
After assessment an identical fresh patch was applied to the same site for a further 17 hours and test sites were examined for irritation 1 hour later.
A third identical fresh patch was applied to the same skin site for a further 23 hours and test sites were examined 1 hour later. Twenty-four out of 26 subjects completed the study. No adverse events were observed.
