Definitions
- this invention relates to N-hydroxycarbanilides having at least two substituents of the group consisting of halogen and trihalomethyl, and which may be further substituted by halogen, nitro, lower alkyl or lower alkoxy radicals; and to non-ionic and anionic detergent compositions containing them.
- a satisfactory purifying finish should be durable and active at low concentrations against a broad spectrum of microorganisms. It should be non-toxic and nonallergenic. It should not have the tendency to sensitize the wearer of the textile fabric to the material of the finish. It should not have the property of allowing strains of bacteria to develop which are resistant to the antibacterial agent of the finish. It should impart little or no color to the fabric and should be stable with respect to color and activity for many months under storage and shipping conditions. It should be resistant to the conditions used in laundering and dry cleaning. It should cause little or no modification of the hand of the textile. It should be substantive to the fiber. It should be compatible with dyes and resins with which it may be in contact on the textile. 1
- substantivity on the fiber and durability of the antibacterial action are two of the most important desirable properties. Without substantivity on the fiber the germicide is merely a coating to be rubbed or washed oif by the first treatment to which it is subjected. substantivity for the fiber is, therefore, one of the main bases upon which durability rests. However, durability must also be a function of the stability of the compound itself to oxidation by air, degradation by light, heat and the like.
- a germicide is to have the widest utility as a textile finish, the best place to use it is in the regular laundering, whether in the home or in a hospital or a commercial laundry. Such a germicidal finish builds up in concentration on the fiber with further Washing since new applications of germicide are made during such further washing.
- This invention is based on the discovery of a new class of compounds, defined above, the members of which have high germicidal action and are substantive to fabrics.
- T955 new compounds may be represented by the structural Formula 1:
- X X X X X X Y Y Y Y and Y are individually either hydrogen, halogen (especially chlorine and bromine), nitro, lower alkyl, lower .alkoxy and trihalomethyl (e.g. trichloromethyl and especially trifluoromethyl), at least two of the X and Y radicals being halogen or trihalornethyl.
- halogen especially chlorine and bromine
- nitro, lower alkyl, lower .alkoxy and trihalomethyl e.g. trichloromethyl and especially trifluoromethyl
- at least two of the X and Y radicals being halogen or trihalornethyl.
- those compounds which have halo and/ or trihalomethyl groups in both phenyl moieties are preferred since they generally show greater germicidal activity than the analogs which are substituted in only one phenyl moiety.
- the new compounds of this invention may be prepared by reacting a phenyl isocyanate with an N-phenylhydroxylamine in the presence of a non-polar halogenated organic solvent (e.g. chloroform) or an aromatic monocyclic hydrocarbon (e.g. benzene, toluene and xylene) at ambient temperatures using approximately equimolar proportions of the reactants.

- the germicides of this invention when padded or exhaust dyed on cloth, show such germicidal activity that Staphylococcus aureus and E. cell, for example, are inhibited not only where in contact with the treated cloth, but in an area beyond. After many Washing cycles, the
- a padded fabric still shows activity against Staphylococcus aureus and E. coli in contact with the cloth.
- germicides of this invention become attached to fibers when applied from an aqueous bath at only slightly elevated temperatures. They have notably strong afiinity for cotton and may be applied to cotton in temperatures as low as those used in laundry procedures. They may also be applied at.th e higher temperatures normally used in the dyeing of cotton, i.e. near the boil. These compounds are thus particularly suitable for hospital and home use, where it is more difficult to attain the temperatures close to the boil that are used in a dyeing mill. In addition to cotton, the germicides of this invention have afiinity for other fibers such as nylon, cellulose acetate and the like when applied from laundry bath. 7
- the compounds of this invention are compatible with non-ionic and anionic detergents. This is a further :advantage of this invention since the germicide can be ap-1 plied from a detergent bath such'as is used in laundering in the home or in a hospital.
- Germicidal compositions including the compounds of this invention in admixture with alkyl aryl sulfonates (anionic detergents) are espe cially suitable compositions for the application for'durable finishes to cotton and other fibers especially during home or commercial laundering procedures. During the process of laundering, the germicide becomes attached to'the fiber and the fiber is thusrendered sterile for long periods.
- a detergent composition having from about 0.01 to 5.0% germicide on the weight of the detergent is an effective composition for this purpose.
- the organic anionic detergents which may be used in the'compositions of this invention include alkali metal fatty acid soaps and, in addition, the well known surfaceactive alkali metal sulfonates and sulfates.
- the latter may be employed as the sole detergent base or in admixture with alkali metal fatty acid soaps, as for example, 1 part of fatty acid soap to 0.5 to '2 parts by weight of the surface-active alkali metal sulfonates or sulfates or mixtures thereof.
- a preferred group of this class is the long chain alkyl aryl sulfonates, i.e., those wherein the alkyl group is straight or branched in structure and contains from 8 to 22 carbon atoms, but preferably 10 to 16 carbon atoms, examples of which being octyl, decyl, dodecyl, pentadecyl, hexadecyl, octadecyl, mixed long chain alkyl' derived from long chain fatty acids such as the lauryl radical, cracked parrafin wax olefins, polymers of low mono-olefins such as propylene tetramer and the like, and wherein the aryl radical is derived from benzene, toluene, xylene, phenol, the cresols, naphthalene and the like. Specific examples of such comprise sodium decylbenzenesulfonate, sodium dodecylbenzenesul
- sodium laurylbenzenesulfonate and sodium hexadecylbenzenesulfonate.
- Other sulfonate surface active agents are contemplated also, as for example, the long chain :alkyl sulfonates such as sodium hexadecyl sulfonate and .and mixed alkyl sulfates, and higher sulfates such as sodium lauryl sulfate and sodium cetyl sulfate.
- Additional .anionic surface active sulfonates and sulfates contemplated by this invention are the sulfonated and sulfated'alkyl acid amides such as Igepon T of the formula C H CONHCH CH SO N21
- Such detergents include sulfuric acid esters of din which R is an alkyl radical containing from 12-18 carbon atoms, the sodium salt of the sulfonic acid derivative of a dialkyl dicarboxylate, disodium sulfosuccinate monoamide such as and the like. ,j In addition to the.

3,189,645 N-HYDROXYCARBANILIDES AND THEIR USE AS BACTERICIDES AND FUNGICIDES Peggy Pamela Hoffman, Somerviiie, and Wiiliam Baptist Hardy, Bound Brook, N.J., assignors to American Cyanamid Company, New York, N.Y., a corporation of Maine No Drawing. Filed Aug. 8, 1961, Ser. No. 129,999 4 Claims. (6]. 269-553) This invention relates to new germicides and to detergent compositions containing these germicides. More specifically this invention relates to N-hydroxycarbanilides having at least two substituents of the group consisting of halogen and trihalomethyl, and which may be further substituted by halogen, nitro, lower alkyl or lower alkoxy radicals; and to non-ionic and anionic detergent compositions containing them.
In recent years, increased attention has been given to the development of textile purifying finishes. These finishes inhibit the growth, and reduce the number of microorganisms on the material. These purifying finishes, when applied to articles of clothing worn close to the body, are also helpful in preventing the development of body odors.
A satisfactory purifying finish should be durable and active at low concentrations against a broad spectrum of microorganisms. It should be non-toxic and nonallergenic. It should not have the tendency to sensitize the wearer of the textile fabric to the material of the finish. It should not have the property of allowing strains of bacteria to develop which are resistant to the antibacterial agent of the finish. It should impart little or no color to the fabric and should be stable with respect to color and activity for many months under storage and shipping conditions. It should be resistant to the conditions used in laundering and dry cleaning. It should cause little or no modification of the hand of the textile. It should be substantive to the fiber. It should be compatible with dyes and resins with which it may be in contact on the textile. 1
Various textile purifying finishes containing anti-bacterial substances such as hexachlorophene, tetrachlorophene, quaternary ammonium compounds such as dimethyl benzyl ammonium chloride, organo-metallic complexes of mercury, copper and silver, and others have been used but are for the most part non-durable and unsatisfactory in other respects, especially in their inability to exhaust from a laundry bath.
substantivity on the fiber and durability of the antibacterial action are two of the most important desirable properties. Without substantivity on the fiber the germicide is merely a coating to be rubbed or washed oif by the first treatment to which it is subjected. substantivity for the fiber is, therefore, one of the main bases upon which durability rests. However, durability must also be a function of the stability of the compound itself to oxidation by air, degradation by light, heat and the like.
Especially important is the property of substantivity under laundering conditions and especially of exhaustion from such a laundry bath in the same way that a dye exhausts from a dye bath. If a germicide is to have the widest utility as a textile finish, the best place to use it is in the regular laundering, whether in the home or in a hospital or a commercial laundry. Such a germicidal finish builds up in concentration on the fiber with further Washing since new applications of germicide are made during such further washing.
This invention is based on the discovery of a new class of compounds, defined above, the members of which have high germicidal action and are substantive to fabrics. The
Fa -tented June 1 5, T955 new compounds may be represented by the structural Formula 1:
wherein the X X X X X Y Y Y Y and Y are individually either hydrogen, halogen (especially chlorine and bromine), nitro, lower alkyl, lower .alkoxy and trihalomethyl (e.g. trichloromethyl and especially trifluoromethyl), at least two of the X and Y radicals being halogen or trihalornethyl. Within the class of compounds constituting this invention those compounds which have halo and/ or trihalomethyl groups in both phenyl moieties are preferred since they generally show greater germicidal activity than the analogs which are substituted in only one phenyl moiety. It has also been found that those compounds having at least one 3,4-dichlorophenyl radical, 3,4,5-trichlorophenyl radical, and particularly a 3,5-dichlorophenyl radical or a S-trifluoromethylphenyl radical show higher activity than those in which the chloro radicals are in the 2- or the 6-positions of the phenyl moieties.
The new compounds of this invention may be prepared by reacting a phenyl isocyanate with an N-phenylhydroxylamine in the presence of a non-polar halogenated organic solvent (e.g. chloroform) or an aromatic monocyclic hydrocarbon (e.g. benzene, toluene and xylene) at ambient temperatures using approximately equimolar proportions of the reactants. The reaction may be represented by the following equation in which X X X X X Y Y Y Y and Y are as hereinbefore defined.
I I I I X -QNCO norm-@414 I I I X5 X5 Ya Ya X3 X2 Y2 Y3 I I I I I 0 X5 i I I As examples of suitable phenyl isocyanates which may be used, these may be named inter alia: phenyl isocyanate, 2-, 3- and 4-chlorophenyl isocyanate, 2,3, 25-, 3,4- and 3,5-dichlorophenyl isocyanate, 3-(trifiuoromethyl)phenyl isocyanate and 3,5-bis(trifluoromethyl)phenyl isocyanate, 2-, 3- and 4-bromophenyl isocyanate, 3,4 and 3,5-dioromophenyl isocyanate, 3,4,5-trichlorophenyl isocyanate, 3- and 4-nitrophenyl isocyanate, 2-, 3- and 4-methylphenyl isocyanate, 3-(trifiuoromethyl) 4 bromophenyl isocyanate, 3-(trifiuoromethyl)-4-chlorophenyl isocyanate and 4-methoxyphenyl isocyanate.
As examples of suitable N-phenylhydroxylamines which may be used, these may be named inter alia: N-phenylhydroxylamine, N-(Z-chlorophenyl)hydroxylamine, N-(4- chlorophenyl)hydroxylamine, N-(3-chlorophenyl)hydroxylamine, N- (4-iodophenyl) hydroxylamine, N- (2,5 -dichlorophenyl)hydroxylamine, N-(3,4-dichlorophenyl)hydroxylamine, N 3,5 dichlorophenyl)hydroxylamine, N 3- (trifiuoromethyDphenyl hydroxylamine, N-3 (trichloromethyl) phenyl hydroxylamine, N-(3,4,5-trichlorophenyl) hydroxylarnine, N-(2-methyl 3 chlorophenyl)hydroxylamine, N- Z-methyl-S-chlorophenyl) hydroxylarnine, and N 2-methyl-4,S-dichlorophenyl hydroxylamine.
The germicides of this invention when padded or exhaust dyed on cloth, show such germicidal activity that Staphylococcus aureus and E. cell, for example, are inhibited not only where in contact with the treated cloth, but in an area beyond. After many Washing cycles, the
a padded fabric still shows activity against Staphylococcus aureus and E. coli in contact with the cloth.
It is an important advantage of the germicides of this invention that they become attached to fibers when applied from an aqueous bath at only slightly elevated temperatures. They have notably strong afiinity for cotton and may be applied to cotton in temperatures as low as those used in laundry procedures. They may also be applied at.th e higher temperatures normally used in the dyeing of cotton, i.e. near the boil. These compounds are thus particularly suitable for hospital and home use, where it is more difficult to attain the temperatures close to the boil that are used in a dyeing mill. In addition to cotton, the germicides of this invention have afiinity for other fibers such as nylon, cellulose acetate and the like when applied from laundry bath. 7
The compounds of this invention are compatible with non-ionic and anionic detergents. This is a further :advantage of this invention since the germicide can be ap-1 plied from a detergent bath such'as is used in laundering in the home or in a hospital. Germicidal compositions including the compounds of this invention in admixture with alkyl aryl sulfonates (anionic detergents) are espe cially suitable compositions for the application for'durable finishes to cotton and other fibers especially during home or commercial laundering procedures. During the process of laundering, the germicide becomes attached to'the fiber and the fiber is thusrendered sterile for long periods. A detergent composition having from about 0.01 to 5.0% germicide on the weight of the detergent is an effective composition for this purpose.
The organic anionic detergents which may be used in the'compositions of this invention include alkali metal fatty acid soaps and, in addition, the well known surfaceactive alkali metal sulfonates and sulfates. The latter may be employed as the sole detergent base or in admixture with alkali metal fatty acid soaps, as for example, 1 part of fatty acid soap to 0.5 to '2 parts by weight of the surface-active alkali metal sulfonates or sulfates or mixtures thereof. A preferred group of this class is the long chain alkyl aryl sulfonates, i.e., those wherein the alkyl group is straight or branched in structure and contains from 8 to 22 carbon atoms, but preferably 10 to 16 carbon atoms, examples of which being octyl, decyl, dodecyl, pentadecyl, hexadecyl, octadecyl, mixed long chain alkyl' derived from long chain fatty acids such as the lauryl radical, cracked parrafin wax olefins, polymers of low mono-olefins such as propylene tetramer and the like, and wherein the aryl radical is derived from benzene, toluene, xylene, phenol, the cresols, naphthalene and the like. Specific examples of such comprise sodium decylbenzenesulfonate, sodium dodecylbenzenesulfonate,
sodium laurylbenzenesulfonate, and sodium hexadecylbenzenesulfonate. Other sulfonate surface active agents are contemplated also, as for example, the long chain :alkyl sulfonates such as sodium hexadecyl sulfonate and .and mixed alkyl sulfates, and higher sulfates such as sodium lauryl sulfate and sodium cetyl sulfate.
Additional .anionic surface active sulfonates and sulfates contemplated by this invention are the sulfonated and sulfated'alkyl acid amides such as Igepon T of the formula C H CONHCH CH SO N21 The sulfated and sulfonated esters such as Igepon AT of the formula Such detergents include sulfuric acid esters of din which R is an alkyl radical containing from 12-18 carbon atoms, the sodium salt of the sulfonic acid derivative of a dialkyl dicarboxylate, disodium sulfosuccinate monoamide such as and the like. ,j In addition to the. anionic surface active agents, nonionic surface active agents may be used as the base for germicidal compositions of our invention. Thenon-ionic surface active agents which may be used are viscous liquid, wax-like, water soluble surface active substances containing a polyglycol ether group of the strucmre Z1 Z2 in which Z and Z are hydrogen or a short chain alkyl,
p is an integer greater than three and Z is a residue of V typified by polyalkylene oxide derivatives (e.g. polyethylene oxide, polypropylene oxide, polybutylene oxide) of water-insoluble higher fatty acids, such as lauric, 'oleic, palmitic and stearic and the like, or'mixtures thereof such as the mixtures of fatty acids obtained from animal and vegetable fats and oils and by the oxidation of petroleum fractions such as parafin wax; They may also be exemplified by the polyalkylene oxide derivatives of such water-insoluble organic hydroxy compounds as higher aliphatic compounds (i.e. the alcohols corresponding to the fatty acids specified above or mixtures thereof) phenols, particularly alkyl phenols containing at.least six alkyl carbon atoms such as isooctyl, triisopropyl, nonyl, dodecyl, octadecyl phenols or naphthols, or of aralkyl alcohols such as benzyl alcohol, cinnamyl alcohol and the like. They may also be exemplified by the polyalkylene oxide derivatives of such amines as 'stearyl, lauryl, dicyclohexyl, dibutyl amine and the like. ticularly useful non-ionic detergent is that obtained by condensing one mole of tall oil with 5-15 moles of' Staphylococcus aureus, that they are effective against the other gram positive bacteria which break down perspiration into odoriferous products.
The germicides .of this invention may also be applied 7 to surfaces. This'can be done in the form of a solution in dimtehylformamide containing 0.01 to 1.0% on the Weight of the germicide. In addition, more concentrated solutions may be added to cleaning materials, floor waxes and the like to give a final concentration of 0.01 to 1.0%
germicide for application to a surface. Such an application produces a surface which is durably germicidali This invention can be illustrated by the following examples in which parts are by weight unless otherwise specified.
