Abstract

Title: DISINFECTANT CLEANER COMPOSITION

ABSTRACT OF THE DISCLOSURE
Disinfectant cleaner compositions containing a small amount of pine oil, alpha terpineol, a surfactant, a stabilizer, and, optionally, ethylenediamine tetraacetic acid or a derivative thereof. The compositions possess ex-cellent bactericidal activity against gram negative organisms.

Description

Z8,31~ ~lS326~

.... . .
~ISrNFECTANT'CL~ANER''COMP~SrTION
The present in~ention relates generally to pine oil-containing disinfectant cleaners and particularly to such cleaners which contain a very small amount of pine oil but nevertheIess exhi'bit excellent germicidal activity against gram negative'organisms. Such activity is due to the fortification of such cleaners with alpha terpin~201.
Cleaning compositions containing pine oil as the active germicidal ingredient are well known and have a wide ~ariety of household, institutional and janitorial uses ~see, ~or example, Pi'n'e'`O'i~ rmul'arY, Section B, Pine and Paper Chemical-~ DeptO, ~ercules, Inc., p. 13-42). ~owever, in order for such compositions to exhibit acceptable germicidal effectiveness against gram negative organisms, either a large }5 a unt of;pine oil must be used, or one or more additional ~' bacter~cidal components ef ective against gram negative oxganlsms must~be incorporated into the formulation.
Large amounts of pine oil in these compositions, howe~er~ result in a residue being left on the treated sur-face. Such'a~residue is undesirable in that it imparts aslipp~ry feel'ing to the surface and al~o acts as a dust ; attractant. Fuxther, pine'oil iq toxic. The quaternary am-monlum and phenoli~ compaunds ~hi'ch have heretQfore been em-pl ffl ed as the additional bacterlcidal components are also ; 25 h~ghly toxic irritants and create serious odor and stability ~ problem~. Therefore, composition~ containing either o~
''~ these~compounds are like~ise'not particul~rly desirable as consumer products, It is accordingly an object of the in~tant inven-'~-?

tion to provide a low level pine oil containing composition which possesses excellent bactericidal activity against gram negative organisms.
It is another object of this invention to provide such a composition which has good consumer appeal due to the fact that it retains the characteristic piny scent of pine oil containing compositions.
It is still a further object of the invention to provide such a composition which possesses good stability.
Other objects and advantages of the invention will beccme apparent from the ensuing description.
It has bsen discovered that when the amount of pine oil in a pine oil containing composition is substantially reduoe d, and sufficient alpha terpineol, a compound having the formNla:

~C ~

is incorporated into the composition, the composition posæ sses excellent bactericidal activity against gram negative organisms. In addition, such a composition retains a pleasant pine odor (the alpha terpineol actually contri-butes to the piny scent), is relatively easily stabilized, and is less toxic.
Accordingly, the present invention provides a disinfectant cleaner composition comprising (1) about 0 to 8 percent, by weight, pine oil; (2) suffic-ient alpha terpineol such that the total alpha terpineol content of thecomposition is at least 5.6 percent, by weight; (3) about 5 to 12 percent, by weight, of a nonionic or anionic surfactant; (4) about 6 to 12 percent, by weight, of a stabilizer; and (5) water.

~1~326~7 In accordance with the present invention, the pine oil content of the composition may ~e reduced such that it is present in an amount of akout 1 to 8 percent, by weight, of the ccmposition. Preferably, pine oil comprises abou~ 3 to 7 percent of the composition. It is also within the scope of the invention to remove all of the pine oil from the composition. ~owever, it is to be noted that when pine oil is completely removed from the composition, the strong pine scent is not present. A piny odor does rem~in, due to - 2a -B

~326'7 the presence of the alpha terpineol, but it ls weaker.
The alpha terpineol is present in the composition in an amount such that the total weight percent of it is not less than 5.6 percent. It being well known that alpha ter-pineol is a principal component of pine oil, achieving this critical weight percentage of alpha terpineol can be accom-plished in one of three ways. First, pine oils ha~ing alpha te~pineol contents of 70% a~d higher are readily commercial-ly available and an amount of such a pine oil sufficient to yield an alpha terpineol l.e~el of 5.6 percent can be incor-porated into the'composition. '(For example, Glidco Pine Oil 150, made by SCM Glidden Organics, typically contains about 75~ alpha terpineol. Having Glidco Pine Oil 150 present in the composition in an amount equal to 7.5~ will result in an alpha terpineol content of ~ust over the critical 5.6 percent leveI. Second, a smaller amount of pine oil (with a corres-pondingly smaller amount of pure alpha terpineol) may be add-ed to the composition, and an amount of pure alpha terpineol, which is readlly c'ommercially available, is then added such that the total alpha terpineol content of the composition-is not less than 506'percent. Finally, the pine oil may be elim-inated ~rom the'composition altogether, and at least 5.6 per-cent of pure alpha terplneol is added. In this last case, ho~ever, thé p~ny scent will not be as strong, as previously noted.
As stated above,` the present invention's composi-tion is easily stabilized, 'To this end, lower alkyl alcohols and glycol compounds, such as propylene glycol and hexylene : glycol, are'employed. A pre~erred stabilizer is isopropyl alcohol. ~he stabilizer is present in an amount sufficient to stabilize the composition. Generally, ~rom about 6 to 12 percent, by weight, of the stabilizer is used. Preferablyr the stabilizer comprises from about 8 to 10 percent o~ .the " compositionO In large part, how.ever, the amount of stabili-: 35 zer requirea in a given ~ormulation will depend upon the types and kinds of the remaining ingredients in the composi-; tion and the optimum type and amount of stabilizer to be used in a gi~en system is best determined by routine experimenta-tion.
A surfactant is also present in the composition to aid in soil remo~al. Any conventional nonionic or anionic surfactant or surfactant system (all of which are well known in the art) may be employed, with the caveat again being that routine experimentation would yield the optim~m surfact-ant for a given formulation~ Examples of non-ionic surfact-ants include ethoxylated alkyl phenols. T~pical anionic sur-factants include alkali metal dodecyl benzyl sulfonates.
1~ Preferred surfactant systems are any of the C12 to C18 fat-ty acids or a combination of more than one such acid, and potassium hydroxideO The surfactant is generally present in the compositlon in an amount of about 5 to 12, prefer-ably 6 to 8, percent by weight.
Optlonally, e~hylene diamine tetraacetic acid (EDTA) or a deri~att~e'thereof is ~ncorporated into the com-position, thereby ~urther enhancing the germicidal activity of the formulation. Although applicants do not want to be bound by any theory,,it is believed that the EDTA (or deri-vati~e) acts upon th~ cell wall of the gram negative organ-ism in such'a ~ay that it is more easily penetrated by the active ingredientg.
Preferably, ,the composition is adjusted to a pH
' of about 9 to 11, preferabIy 9.5 to 10~5. Should such an adjustment be necessary, it is typically made by addition of an alkali, such'as potassium or sodium hydroxide.
The remainder of the composition is comprised of water, although additional ingredients, such as dyes, bright-eners and the llke may be incorporated without departing from the scope of the invention.
The following examples are illustrative of the present in~ention but are not to be construed in any way as a limitation thereof. Al~ parts and percentages are by weight unless otherwise indicated.

Exam~
The compositlons of Examples 1, 2 and 3 were tested for efficacy in killing gram negative organisms using the Association of Oficial Analytical Chemists (A.O~A.C.) Use Dilution Test, which appears in the A.O.A.C. Methods manual, 13th edition (1980). The test is the official test method recognized by the U.S. En~ironmental Protection Agency (EPA) for registration and regulation of germicidal compositions for disinfectant activity. The gram negative test organ~sm employed was SalmoneIla choleraesuis, Results of the A.O.A.C. Use-Dilutton Test fox the compositions of Examples 1-3, wherein each composition was diluted as shown, are set forth in TabIe 1 below. A score of 59/60 or 60/60 is considered a passing scoreO
