United States Patent 3,484,523 QUATERNARY AMMONlUM-TERTIARY AMINE OXIDE COMPOSITIONS John C. Findlan, Chappaqua, and Ralph P. Sorrentino,
Elmhurst, N.Y., and Reginald L. Wakeman, Philadelphia, Pa., assignors to Millmaster Onyx Corporation, New York, N.Y., a corporation of New York N 0 Drawing. Continuation-impart of application Ser. No. 500,282, Oct. 21, 1965. This application Dec. 27, 1966, Ser. No. 604,598 The portion of the term of the patent subsequent to Jan. 3, 1984, has been disclaimed Int. Cl. A61k 27/00; C11d 1/62 U.S. Cl. 424-448 3 Claims ABSTRACT OF THE DISCLOSURE A composition for both cleaning and degerming human skin and similar organic tissue, consistlng of at least one tertiary amine oxide of the formula:
wherein R is a member of the group consisting of alkyl and alkenyl having 8 to 20 carbon atoms, and R and R" are selected from the group consisting of lower alkyl, hydroxy lower alkyl and individual valences of heterocyclic radicals such as morpholine, and at least one germicidal quaternary ammonium compound having a phenol co eflicient of at least 100 with respect to Staphylococcus aureus and Salmonella typhosa at 20 C., the amine oxide and quaternary compounds being respectively present in a proportion of between less than 5:1 to about 0.5: 1, by weight.
where R contains from 8 to 20 carbon atoms and may, if desired, be unsaturated in nature, where R and R" may be methyl, ethyl, propyl, isopropyl, hydroxyethyl, hydroxyethoxyethyl or hydroxyethyl polyethoxyethyl radicals and wherein the oxygen is linked to nitrogen by means of a semi-polar bond. If desired, R and R" may jointly constitute the CH 'CH O-CH CH radical, i.e. the above formula is:
While all of these amine oxides have detersive power, those containing fourteen carbon atoms, or less, are also good foaming agents whereas those possessing 16 carbon atoms, or more, are poor foaming agents.
As suitable quaternary ammonium compounds utilizable in the compositions of this invention, there may be employed any water-soluble quaternary ammonium salt having a long alkyl radical containing from 8 to 22 carbon atoms attached either directly to the nitrogen atom or through an intermediate benzyl or phenoxy ethyl radical and having a phenol coefficient of at least with respect to the Staphylococcus aureus and Salmonella typhosa at 20 C. when determined by the standard method given in the Oificial Method of Analysis of the Association of Oflicial Agricultural Chemists, Ninth Edition (1960), page 63 et seq. Typical examples of these quaternary ammonium compounds are alkyl trimethyl ammonium chlorides, alkyl-benzyl trimethyl ammonium chlorides, alkyl dimethyl benzyl ammonium chlorides, alkyl dimethyl menaphthyl ammonium chlorides, alkyl dimethyl substituted benzyl ammonium chlorides in which the benzyl radical is substituted with one or more side chains containing from 1 to 5 carbon atoms such, for example, as methyl, dimethyl, ethyl, isopropyl, ter-butyl, n-amyl, isoamyl, tetramethyl, trimethyl and the like in which the carbon atoms may all be in the same or different side chains or in which the benzyl radical may be substituted by .an alkylene group such as tetrahydro menaphthyl or in which the benzyl radical bears one, two or more halogen atoms such as chlorine or bromine, alkyl pyridinium chlorides, alkyl isoquinolinium chlorides and bromides alkyl lower-alkyl pyrrolidinium chlorides, alkyl lower-alkyl morpholinium chlorides in all of which the alkyl group may have from 8 to 22 carbon atoms and the lower-alkyl group may have from 1 to 4 carbon atoms and alkyl phenoxyethoxyethyl dimethylbenzyl ammonium chloride in which the alkyl radical may be iso-octyl or nonyl and in which the benzyl radical may, if desired, be substituted by a methyl radical. Various other analogs of these quaternaries may also be employed such, for example, as cetyl dimethyl ethyl ammonium bromide or oleyl dimethyl ethyl ammonium bromide. Instead of the foregoing chlorides, there may also be employed the corresponding bromides, methosulfates, ethosulfates or other water-soluble analogs. Mixtures of two or more of the foregoing quaternary ammonium compounds may also be employed. In particular, it is preferred to employ a mixture of alkyl dimethyl benzyl ammonium chloride in which the alkyl radical blend contains at least 50% myristyl, together with alkyl dimethyl ethyl-benzyl ammonium chloride in which the alkyl radical blend is predominantly (at least 50%) C this blend being employed in approximately 1:1 ratio, by Weight.
It is preferred to use the quaternary ammonium compounds which have phenol coefficients of more than 500 against Staphylococcus aureus; such, for example, are ETC-824, an alkyl dimethyl benzyl ammonium chloride in IS C14, C15, C12 and C18; Tetrosan 3,4 D, an alkyl dimethyl dichlorobenzyl ammonium chloride in which alkyl is 50% C 30% C 17% C and 8% C BTC471 and ETC-927, which are, respectively, alkyl dimethyl ethyl-benzyl and alkyl dimethyl dimethylbenzyl ammonium chlorides in which the alkyl distribution is the same as in Tetrosan 3,4 D; lauryl dimethyl menaphthyl or tetrahydromenaphthyl ammonium chloride; lauryl isoquinolinium bromide and the like; or mixtures thereof. The aforesaid products are sold by Onyx Chemical Company under the previously mentioned trademark designations.
The compositions of this invention are preferably prepared as liquids for convenient use as a surgical or other degerming scrub soap. However, if desired, they may be thickened by certain additives into a gel or a paste or to be molded into a bar by methods well known to the art; or they. may be prepared as a powder, as, for example, as an adduct with urea, by mixing the composition with crystalline urea in sufiicient amounts to produce a free-flowing powder.
The aforementioned application Serial No. 500,282, and its abandoned parent application Serial No. 339,307,
filed January 21, 1964, indicated that a proportion of about 50:1 to about 5:1 of the disclosed amine oxide relative to the disclosed quarternary ammonium compounds could be utilized for the disclosed purposes. It has, however, now been unexpectedly discovered that thisproportion can be as low as 0.5 :1 and still be compatible with the anionic surface active agents as well as providing very effective microbiocidal action.
The following example illustrate the present invention, but are not to be considered limitative thereof except as claimed:
