A liquid water-miscible disinfectant cleaner composition comprising pine oil in an amount sufficient to provide from 3 to 12 percent by weight of terrapin alcohols, 0.5 to 2.5 percent by weight o-phenylphenol, 4 to 15 percent by weight of a soap, 5 to 15 percent by weight of a C2-4 aliphatic monhydric alcohol, and the balance water.
Description
This invention relates to disinfectant cleaner compositions, and more particularly to water-miscible liquid disinfectant cleaner concentrates based on ortho-phenylphenol and pine oil.
Pine oil, because of its high bactericidal active fly, wetting and penetrating properties, and pleasant ire-grange, has been employed for many years as a constituent of liquid disinfectant cleaner compositions useful for cleaning, disinfecting and deodorizing a wide variety of surfaces and as an aid in laundering operations, both in the household and in commercial establishments; see Pine Oil Formulary, Section s, Pine and Paper Chemicals Department, Hercules Incorporated pages 13-46.
Pine oil-based disinfectant deodorizer cleaner compositions basically consist of pine oil, a soap, a surface lent, a buffering agent and isopropyl alcohol in an aqueous system. The amount of pine oil employed in such compositions will depend, among other things, on the disinfectant activity desired and on its content of terrapin alcohols, to which its bactericidal properties are attributable, and may range from about 1 to 80% by weight of the composition. Thus, for example, such a composition will require sufficient pine oil to provide at least 15% by weight of the composition DUN. AYE
DUN. 5222 A
7'78 of terrapin alcohols in order to meet the requirement for a disinfectant against Salmonella choleraesuis when tested according to the AWOKE. Use-Dilution Method - Official Final Action (198G).
In certain cases, in order to achieve specifically desired disinfectant properties, particularly in those cases when it is desired to reduce the amount of pine oil in a composition, it is necessary to fortify the pine oil compost-lion with an additional disinfecting agent such as a finlike or qua ternary ammonium halide compound. To date the propane-derange of commercially available fortified liquid disinfectant concentrates employ o-benzyl-p-chlorophenol as the additional disinfecting agent.
Three currently available commercial pine oil products of the fortified type are identified on their labels as having the following compositions:
Ingredient _ Percent __ _ A B C
Pine Oil 35.2 30.0 15.0 20 Isopropanol 10.9 12.0 6.0 o-Benzyl-p-chlorophenol - 0.1 2.0 p-Chloro-o-phenylphenol 2.2 Soap 10.0 10.8 8.5 Sodium salt of ethylene Damon twitter acetic acid - _ 0 3 Inert ingredients 41.7 47.1 68.2*
*Water and coloring Pine oil disinfectant compositions of the fortified type which contain either o-benzyl-p-chlorophenol or p-chloro-o-phenylphenol as the additional disinfecting agent are disclosed in Pine Oil Formulary, swooper.
DUN. 5222 US. Patent 2,289,476 discloses two disinfectant emulsions comprising o-phenylphenol, isopropyl alcohol, steam distilled pine oil and sulfonated castor oil. The o-phenylphenol is present in the one composition in 2 parts 5 and the other in 3 parts per part by weight of the pine oil.
US. Patent 3,703,472 discloses detergent compositions comprising inter aria soap, p-chloro-o-benzyl-phenol, pine oil and ammonia having a predominant ammonia it odor at the product level and a predominant pine odor at the use dilution level.
US. Patent 2,359,241 discloses water-miscible liquid germicidal concentrates including o-phenylphenol dispersed therein as the principle toxic ingredient and from 0.25 to 4 parts of pine oil or alpha-terpineol per part by weight of o-phenylphenol/ and which contain sodium hydroxide, potassium cocoanut-oil soap or potassium linseed oil soap, isopropyl alcohol and water.
British Patent Specification 1,583,765 discloses liquid disinfectant compositions comprising a finlike compound such as o-phenylphenol or o-benzyl-p-chlorophenol, pine Oil, a water-soluble C12_20 olefin sulfonate or alkyd sulfonate, water and optionally a lower alkanol, e.g.
isopropyl alcohol, wherein the amount of pine oil incorporated is between about l and 4 parts per part by weight of the finlike compound.
It has been found that pine oil-based deodorizer cleaner compositions containing an amount of pine oil which provides substantially less than 15 weight-percent of terrapin alcohols are effective as disinfectants against Salmonella choleraesuis when tested in accordance with the AWOKE.
Use-Dilution Method-Official final Action (applicable to testing disinfectants miscible with water to determine maximum dilutions effective for practical disinfection) (Official Methods of Analysis of the Association of Official Analytical Chemists, Thea Ed., 1980, pages 58-59) if the compositions have incorporated therein o-phenylphenol.
Thus the invention provides a liquid water-miscible disinfectant cleaner composition which comprises as essential components: (A) a pine oil containing at least 50 weight-percent of terrapin alcohols, (B) o-phenylphenol, (C) a soap, (D) an aliphatic mandrake C2 4 alcohol, and (E) water;
wherein, based on the total weight of components (A), (B), (C), (D) and (E), said composition contains component (~) in an amount sufficient to provide from about 3 to 12 percent by weight of terrapin alcohols, component (B) in an amount of from about 0.5 to 2.5 percent by weight, component (C) in an amount of from about 4 to 15 percent by weight, component (D) in an amount of from about 5 to 15 percent by weight, and the balance to 100 percent, water; the combined terrapin alcohols being present in at least 4.5 parts per part by weight of component (B).
Pine oils are commercially available terpene-rich oils -the major constituent of which is alpha-terpineol and which also contain other terrapin alcohols as well as terrapin hydrocarbons. The terrapin alcohols constitute the bee-tericidally active components of the pine oils and the total terrapin alcohol content of the pine oils can vary over a wide range, typically from about 50 to 90 weight-percent.
The pine oils used in the compositions of the invention should have a total terrapin alcohol content of at least about 50 weight-percent. A preferred pine oil is Glidco~ Pine Oil 60 because a major portion of the terrapin hydrocarbon content thereof is dipentene which contributes to solvent power and pleasingly modifies the fragrance. Glidco~Pine Oil 60, obtainable from SCM Corporation, has a terrapin alcohol content of approximately 60%. The amount of pine oil employed is preferably sufficient to provide from about 9 to 12 percent, e.g. 9 to 10 percent, by weight of terrapin alcohols based on the total weight of the essential components of the composition.
The amount of o-phenylphenol employed in the compositions of the invention is preferably from about 0.7 to 2.5 percent, e.g. 0.7 to 0.8 percent, by weight based on the total weight of the essential components of the composition.
I I
The soaps employed in the compositions of the invention are selected from the sodium and potassium salts of fatty acids, preferably C12 18 fatty acids, derived from rosin, tall oil, vegetable oils or fats, or animal oils or fats, or mixtures thereof. The sodium and potassium salts of tall oil fatty acid are particularly preferred. The amount of soap used is preferably from about 8 to 15 percent, e.g. 8 to 9 percent, by weight based on the total weight of the essential components of the composition.
The alcohols used in the compositions of the invent lion are selected from C2 4 aliphatic mandrake alcohols, i.e., ethyl alcohol, propel alcohol, isopropyl alcohol, n-butyl alcohol, secondaxy-butyl alcohol and tertiary-butyl alcohol. The alcohol aids in solubilizing the pine oil, o-phenylphenol and soap and is required to ensure low temperature stability of the o-phenylphenol. Isopropyl alcohol is a preferred alcohol . The amount of alcohol employed is preferably from about 11 to 15 percent, e.g. 11 to 12 percent, by weight based on the total weight of the essential components of the composition.
The compositions of the invention are formulated as aqueous concentrates, the amount of water used being sufficient to provide the balance to 100 percent by weight based on the total weight of the essential ingredients of the composition.
In addition to the essential components, the compost-lions of the invention may have incorporated therein optional ingredients such as anionic surfactants, agents to control phi antioxidant and colorants.
,>~5~7~ No 5222 A
Anionic surfactants can be added as foam boosters as well as to improve wetting and provide added detergency.
Anionic surfactants which can be employed are, for example, C12_20 alkyd and olefin sulfates and sulfonates and alkyd aureole sulfonates. If employed, the anionic surfactants prefer-rawly are incorporated in amounts such that the combined weight of the soap and surfactant does not exceed about 16 percent based on the total weight of the essential components of the composition.
The compositions of the invention have a pi above 7. Preferably the pi should be 8~5 or higher since below pi 8.5 there is a tendency for at least a part of the soap to precipitate. A preferred pi range is 8.5 to 10. The pi may be regulated by the addition of an appropriate amount of a suitable alkaline reacting agent or buffer such as are well known, e.g., sodium carbonate, sodium bicarbonate, sodium metasilicate, tetrasodium ethylenediaminetetraacetate, dip and trisodium salts of nit lotriacetic acid MindWrite, trisodium phosphate, alkali metal hydroxide, etc.
The compositions of the invention can be used to clean, disinfect and deodorize a variety of hard surfaces in the household such as floors, walls, woodwork, sinks, tubs, toilets, tiles, etc. The compositions may also be used as an aid in laundering operations. Although in certain circumstances it may be desirable to use the compositions of the invention full strength, e.g., to remove stains in clothing prior to laundering, the compositions generally - -are diluted with water before use. On diluting the compositions with water a blooming effect is obtained, i.e., the diluted composition becomes milky in appearance. A practical use dilution should contain at least 100 parts per million of o-phenylphenol.

Pine oil, because of its high bactericidal active fly, wetting and penetrating properties, and pleasant ire-grange, has been employed for many years as a constituent of liquid disinfectant cleaner compositions useful for cleaning, disinfecting and deodorizing a wide variety of surfaces and as an aid in laundering operations, both in the household and in commercial establishments; see Pine Oil Formulary, Section s, Pine and Paper Chemicals Department, Hercules Incorporated pages 13-46.
Pine oil-based disinfectant deodorizer cleaner compositions basically consist of pine oil, a soap, a surface lent, a buffering agent and isopropyl alcohol in an aqueous system. The amount of pine oil employed in such compositions will depend, among other things, on the disinfectant activity desired and on its content of terrapin alcohols, to which its bactericidal properties are attributable, and may range from about 1 to 80% by weight of the composition. Thus, for example, such a composition will require sufficient pine oil to provide at least 15% by weight of the composition DUN. AYE

In certain cases, in order to achieve specifically desired disinfectant properties, particularly in those cases when it is desired to reduce the amount of pine oil in a composition, it is necessary to fortify the pine oil compost-lion with an additional disinfecting agent such as a finlike or qua ternary ammonium halide compound. To date the propane-derange of commercially available fortified liquid disinfectant concentrates employ o-benzyl-p-chlorophenol as the additional disinfecting agent.
Three currently available commercial pine oil products of the fortified type are identified on their labels as having the following compositions:

It has been found that pine oil-based deodorizer cleaner compositions containing an amount of pine oil which provides substantially less than 15 weight-percent of terrapin alcohols are effective as disinfectants against Salmonella choleraesuis when tested in accordance with the AWOKE.
Use-Dilution Method-Official final Action (applicable to testing disinfectants miscible with water to determine maximum dilutions effective for practical disinfection) (Official Methods of Analysis of the Association of Official Analytical Chemists, Thea Ed., 1980, pages 58-59) if the compositions have incorporated therein o-phenylphenol.
Thus the invention provides a liquid water-miscible disinfectant cleaner composition which comprises as essential components: (A) a pine oil containing at least 50 weight-percent of terrapin alcohols, (B) o-phenylphenol, (C) a soap, (D) an aliphatic mandrake C2 4 alcohol, and (E) water;
wherein, based on the total weight of components (A), (B), (C), (D) and (E), said composition contains component (~) in an amount sufficient to provide from about 3 to 12 percent by weight of terrapin alcohols, component (B) in an amount of from about 0.5 to 2.5 percent by weight, component (C) in an amount of from about 4 to 15 percent by weight, component (D) in an amount of from about 5 to 15 percent by weight, and the balance to 100 percent, water; the combined terrapin alcohols being present in at least 4.5 parts per part by weight of component (B).
Pine oils are commercially available terpene-rich oils -the major constituent of which is alpha-terpineol and which also contain other terrapin alcohols as well as terrapin hydrocarbons. The terrapin alcohols constitute the bee-tericidally active components of the pine oils and the total terrapin alcohol content of the pine oils can vary over a wide range, typically from about 50 to 90 weight-percent.
The pine oils used in the compositions of the invention should have a total terrapin alcohol content of at least about 50 weight-percent. A preferred pine oil is Glidco~ Pine Oil 60 because a major portion of the terrapin hydrocarbon content thereof is dipentene which contributes to solvent power and pleasingly modifies the fragrance. Glidco~Pine Oil 60, obtainable from SCM Corporation, has a terrapin alcohol content of approximately 60%. The amount of pine oil employed is preferably sufficient to provide from about 9 to 12 percent, e.g. 9 to 10 percent, by weight of terrapin alcohols based on the total weight of the essential components of the composition.
The amount of o-phenylphenol employed in the compositions of the invention is preferably from about 0.7 to 2.5 percent, e.g. 0.7 to 0.8 percent, by weight based on the total weight of the essential components of the composition.

The soaps employed in the compositions of the invention are selected from the sodium and potassium salts of fatty acids, preferably C12 18 fatty acids, derived from rosin, tall oil, vegetable oils or fats, or animal oils or fats, or mixtures thereof. The sodium and potassium salts of tall oil fatty acid are particularly preferred. The amount of soap used is preferably from about 8 to 15 percent, e.g. 8 to 9 percent, by weight based on the total weight of the essential components of the composition.
The alcohols used in the compositions of the invent lion are selected from C2 4 aliphatic mandrake alcohols, i.e., ethyl alcohol, propel alcohol, isopropyl alcohol, n-butyl alcohol, secondaxy-butyl alcohol and tertiary-butyl alcohol. The alcohol aids in solubilizing the pine oil, o-phenylphenol and soap and is required to ensure low temperature stability of the o-phenylphenol. Isopropyl alcohol is a preferred alcohol . The amount of alcohol employed is preferably from about 11 to 15 percent, e.g. 11 to 12 percent, by weight based on the total weight of the essential components of the composition.
The compositions of the invention are formulated as aqueous concentrates, the amount of water used being sufficient to provide the balance to 100 percent by weight based on the total weight of the essential ingredients of the composition.
In addition to the essential components, the compost-lions of the invention may have incorporated therein optional ingredients such as anionic surfactants, agents to control phi antioxidant and colorants.
,>~5~7~ No 5222 A
Anionic surfactants can be added as foam boosters as well as to improve wetting and provide added detergency.
Anionic surfactants which can be employed are, for example, C12_20 alkyd and olefin sulfates and sulfonates and alkyd aureole sulfonates. If employed, the anionic surfactants prefer-rawly are incorporated in amounts such that the combined weight of the soap and surfactant does not exceed about 16 percent based on the total weight of the essential components of the composition.
The compositions of the invention have a pi above 7. Preferably the pi should be 8~5 or higher since below pi 8.5 there is a tendency for at least a part of the soap to precipitate. A preferred pi range is 8.5 to 10. The pi may be regulated by the addition of an appropriate amount of a suitable alkaline reacting agent or buffer such as are well known, e.g., sodium carbonate, sodium bicarbonate, sodium metasilicate, tetrasodium ethylenediaminetetraacetate, dip and trisodium salts of nit lotriacetic acid MindWrite, trisodium phosphate, alkali metal hydroxide, etc.
