filed Nov. 16, 1970, now US. Pat. No. 3,726,815.

The invention relates to improved compositions comprising a water-soluble and/or water-insoluble active material having the capacity to impart a residual characteristic to surfaces treated therewith such as antibacterial compounds, tarnish inhibitors, ultra-violet absorbers, fluorescent brighteners, bluing agents and skin treating materials and an aminopolyureylene (APU) resin in an amount effective to enhance the effects of the active materials. The APU resins appear to enhance the deposition and/or retention of thewater-soluble and waterinsoluble active substances on the surfaces contacted therewith.

The capacity of the APU resin to improve the effectiveness of the active materials on surfaces contacted therewith surprisingly is maintained in the presence of water-soluble organic detergents and, therefore, detergent compositions containing the mixture of active material and APU resin represent preferred embodiments. Such detergent compositions include dishwashing detergents, shampoos, laundry detergents, hardsurface cleaners and toilet bars. The effectiveness of the APU resins in the presence of minor and major amounts of watersoluble organic detergents is surprising because the effectiveness of the active materials is due to the deposition and/or retention of the active materials on surfaces contacted therewith and detergents normally tend to minimize deposition and retention of such materials on the washed surfaces. Thus, usually only a small percentage of the active materials in a detergent composition is actually retained ona particular surface or substrate after washing and, optionally, rinsing. Accordingly, to achieve a particular level of activity, the concentrations of active material must be increasedwith an attendant increase in cost when used as a component in a detergent composition.

While the mechanism by which the improved effects are obtained is not understood, it appears that the APU resin may unite either with the active material or'thecontacted surface to increase the affinity of the active material for the surface. In many cases, an increase in the weight of active material retained by the surface has been quantitatively verified. However, no absolute mechanism has been defined and the invention is not limited to any particular theory.

Generally, the improved compositions of this invention consist essentially of a mixture of i an aminopolyureylene resin having a molecular weight in the range of about 300 to 100,000 and a water-soluble or water-insoluble active material having the capacity to impart a residual property to surfaces treated therewith and selected from the group consisting of (A) antibacterial compounds, (B) tarnish inhibitors, (C) ultraviolet absorbers, (D) optical brighteners, (E) bluing agents and (F) skin-treating compounds, the weight ratio of resin to active material being effective to improve the effects of the active material and selected from the range of 1:1 to :1 preferably 1:1 to 5:1. Preferred compositions are detergent compositions comprising 2% to 99% by weight of a water-soluble, organic detergent, 0.05% to 5% by weight of aminopolyureylene resin and about 0.05 to 5% by weight of active material.

Also, within the scope of the invention is a method for improving the effectiveness of active materials on surfaces contacted therewith which comprises contacting the surface with a water solution or dispersion of 5 the active material and an effective amount of the aminopolyureylene resin sufficient to improve the effect of the active material retained on the treated surface after the contacting solution is removed.

The APU resins suitable for use in the described compositions and method have a molecular weight. in the range of about 300 to 100,000 and are characterized by the following repeating unit: -[-(CI-I ),,X- (CH ),,NHC(Y)NH+ wherein X is NH, NC to C alkyl, 7

en ca 4.2 2;; \CH2 CH2,

Generally, the number of repeating units in the resin will be sufficient to yield a polymer having a molecular weight in the range of about 300 to 100,000. Preferred APU resins have an average molecular weight in the range of 1,000 to 20,000 and a particularly preferred resin is the reaction product of equimolar quantities of N-methyl, bis(3-amino-propyl) amine and urea having a molecular weight of about 4,300.

The molecular weight of the APU resins is based upon aqueous gel permeation chromatographic analysis. The separation is carried out in oxalic acid solution, adjusted to pH 3.5, on three Corning controlled-pore glass columns (nominal pore sizes 175,125 and 75A) in series. Detection is by differential refractometer. Reference compounds are dextran polysaccharides of molecular weights of 150,000, 110,000, 40,000, 20,000 and 10,000 and sucrose and galactose.

The APU resins which can be used in the compositions of this invention are prepared by reacting, for example, 145 grams of N-methyl bis (3-aminopropyl) amine (1.0 mole) and grams of urea (1.0 mole) in a 3-necked flask equipped with a therometer, mechanical stirrer, condenser, and nitrogen sparge tube. Nitrogen is bubbled slowly through the solution throughout the course of the reaction. The solution is heated to piperazine or N,N-di (2-aminoethyl) piperazine with urea or thiourea. The'N-C, to C alkyl analogues are prepared by reacting N-C to C alkyl bis(3- aminopropyl) amine or N-C to C alkyl bis(2- aminoethyl) amine with urea or thiourea. Additional analogues are prepared by the following reactions:

Suitable proteins are watersoluble polypeptides, having a molecular weight in the range of about 120 (amino acid to about 20,000, preferably from about 800 to 12,000. Such polypeptides are obtained by hydrolysis of protein rna terials such as hides, gelatinjcollagen, and the like, with collagen protein being preferred, using wellknown processes. During hydrolysis the protein materials are gradually broken down into their constituent polypeptides and amino acids by prolonged heating with acids, e.g., sulfuric acid, or alkalis, e.g., sodium hydroxide, or treatment with enzymes, e.g., peptidases. First, high molecular weight polypeptides are formed, and as hydrolysis proceeds these are converted progressively to simpler and simpler polypeptides, to tripeptides, dipeptides, and finally to amino acids. It is'obvious that the polypeptides derived from proteins are complex mixtures. The preferred hydrolysates are ob; tained. from boneor skin-derived collagen protein by enzymatic hydrolysis and are sold under the trade;

Suitable salts include the ammonium, substituted ammonium (mono-, di-, and triethanolammonium), alkali metal (such as sodium and potassium) and alkaline earth metal (such as calcium and magnesium) salts. Preferred salts are the ammonium, triethanolammonium, sodium, and potassium salts of the higher alkyl sulfates and the C to C acyl sarcosinates.

The nonionic synthetic organic detergents are generally the condensation product of an organic aliphatic or alkyl aromatic hydrophobic compound and hydrophilic ethylene oxide groups. Practically any hydrophobic compound having a carboxy, hydroxy, amido, or amino group with a free hydrogen attached to the nitrogen can be condensed with ethylene oxide or with the polyhydration product thereof, polyethylene glycol, to form a nonionic detergent. Further, the length of the polyetheneoxy chain can be adjusted to achieve the desired balance between the hydrophobic and hydrophilic elements.

The nonionic detergents include the polyethylene oxide condensate of one mole of alkyl phenol containing from about 6 to 12 carbon atoms in a straightor branched-chain configuration with about to 30 moles of ethylene oxide, for example, nonyl phenol condensed with 9 moles of ethylene oxide, dodecyl phenol condensed with 15 moles of ethylene and dinonyl phenol condensed with 15 moles of ethylene oxide. Condensation products of the corresponding alkyl thiophenols with 5 to 30 moles of ethylene oxide are also suitable.

Still other suitable nonionics are the polyoxyethylene polyoxypropylene adducts of l-butanol. The hydrophobe of these anionics has a minimum molecular weight of 1,000 and consists of an aliphatic monohydric alcohol containing from 1 to 8 carbon atoms to which is attached a heteric chain of oxyethylene and oxypropylene. The weight ratio of oxypropylene to oxyethylene covers the range of 95:5 to 85:15. Attached to this is the hydrophilic polyoxyethylene chain which is from 44.4 to 54.6 of the total molecular weight.

Also included in the nonionic detergent class are the condensation products of a higher alcohol containing about 8 to 18 carbon atoms in a straight or branchedchain configuration condensed with about 5 to 30 moles of ethylene oxide. for example, lauryl-myristyl alcohol condensed with about 16 moles of ethylene oxide.

A particularly useful group of nonionics is marketed under the trade name Pluronics. The compounds are formed by condensing ethylene oxide with a hydrophobic base formed by the condensation of propylene oxide with propylene glycol. The molecular weight of the hydrophobic portion of the molecule is of the order of 950 to 4,000 and preferably 1,200 to 2,500. The addition of polyoxyethylene radicals to the hydrophobic portion tends to increase the solubility of the molecule as a whole. The molecular weight of the block polymers varies from 1,000 to 15,000, and the polyethylene oxide content may comprise 20 to 80 percent by weight.

Zwitterionic detergents such as the betaines and sulfobetaines having the following formula are also useful:

wherein R is an alkyl group containing about 8 to 18 carbon atoms, R and R are each an alkylene or hydroxyalkylene group containing about 1 to 4 carbon atoms, R is an alkylene or hydroxyalkylene group containing 1 to 4 carbon atoms, and X is C or 8:0. The alkyl group can contain one or more intermediate linkages such as amido, ether, or polyether linkages or nonfunctional substituents such as hydroxyl or halogen which do not substantially affect the hydrophobic character of the group. When X is C, the detergent is called a betaine; and when X is 5:0, the detergent is called a sulfobetaine or sultaine. Preferred betaine and sulfobetaine detergents are l-(lauryl dimethylammonio) acetate, l-(myristyl dimethylammonio) propane-3- sulfonate, and l-( myristyldimethylammonio )-2- hydroxy-propane-3-sulfonate.

The polar nonionic detergents are those in which the hydrophilic group contains a semi-polar bond directly between two atoms, for example, N O, P 0, As O, and S *'O. There is charge separation between the two directly bonded atoms, but the detergent molecule bears no net charge and does not dissociate into ions.

The polar nonionic detergents of this invention include open-chain aliphatic amide oxides of the general formula R R R N O. For the purpose of this invention R is an alkyl, alkenyl, or monohydroxyalkyl radical having about 10 to 16 carbon atoms, R and R are each selected from the group consisting of methyl, ethyl, propyl, ethanol, and propanol radicals.

Other operable polar nonionic detergents are the openchain aliphatic phosphine oxides having the general formula R R R P 0 wherein R is an alkyl, alkenyl, or monohydroxyalkyl radical ranging in chain length from 10 to 18 carbon atoms, and R and R are each alkyl and monohydroxyalkyl radicals containing from 1 to 3 carbon atoms.

Examples of suitable ampholytic detergents include the alkyl beta-aminopropionates, RN(H)C H COOM; the alkyl betaiminodipropionates, RN(C H COOM) the alkyl and hydroxy alkyl taurinates, RN(CH )C H SO M; and the long-chain imidazole derivatives having the following formulas:

Each of the foregoing detergent compositions can be prepared by methods well known in the art. For example, shampoos and built liquid detergents are prepared by mixing, and particulate laundering detergents are prepared by mixing, chemical drying or spray drying.

The ability of the APU resins to potentiate the deposition of the water-insoluble materials which function as antibacterial agents onto proteinaceous substrates, such as hair and skin, is demonstrated in the following radioactive substantivity test. Substantivity is determined by stirring a 1.27-centimeter diameter circular gelatin disk weighing about 40 milligrams for about five minutes in 10 grams of an aqueous medium containing a known concentration of radioactive tagged material such as zinc Z-pyridinethiol-l-oxide, rinsing the disk five times in 10 milliliters of water, drying, and measuring the radiation emission with the aid of a radiation detector. The absolute degree of deposition of the material is determined by comparing the observed counts with the counts emitted by a known weight of the radioactive material. The effect of APU resin on deposition can be readily ascertained by repeating the test with a known weight of APU present. Similarly, the effect of detergents can be quantitatively measured by including detergents in the test composition.

The following examples are illustrative of the compositions falling within the scope of this invention.

EXAMPLE 1 An aqueous dispersion of zinc 2-pyridinethiol-loxide is prepared by dispersing 0.04 grams of radioactive zinc Z-pyridinethiol-l-oxide containing zinc 65 in one gram of water. The resultant aqueous dispersion is diluted with 8.96 grams of water with agitation, and the substantivity of the diluted dispersion is determined using the foregoing substantivity procedure. The results of the evaluation indicate 40.9 micrograms of zinc-2-pyridinethiol-l-oxide are deposited on the disk from the aqueous mixture containing 0.4 percent by weight of the Z-pyridinethiol-l-oxide. When the foregoing experiment is repeated in the presence of an amino polyureylene resin (Resin A) having a molecular weight of about 4,300 and the repeating unit (CI-l N(CH )(C1-1 N(H)C(O)N(1l)-, 122 micrograms of zinc 2-pyridinethiol-l-oxide are deposited on the disk at a concentration of 0.5 percent of said resin in the aqueous test dispersion. Thus, the presence of 0.5 percent of APU resin results in a 200 percent increase in the deposition of zinc-2-pyridinethiol-l-oxide from an aqueous medium.

Use of a resin having a molecular weight of about 5,600 and N,N'-di(3-aminopropyl) piperazine as the repeating unit in the foregoing test yields comparable results.

EXAMPLE 2 When the procedure of Example 1 is repeated using an aqueous solution of 0.25 percent by weight of radioactive (C-14) cetyl trimethylammonium bromide (CTAB) at pH 4.5 as the test medium, 294 micrograms of CTAB are deposited on the gelatin disk. Repetition of this test in the presence of 0.75 percent by weight of the APU resin used in Example 1 results in the deposition of 679 micrograms of CTAB, an increase in deposition of about 130 percent. When the pH of the test solution is increased to 8.5, a deposition of 259 micrograms of CTAB is obtained in the absence of APU resin and a deposition of 734 micrograms is obtained in the presence of 3 percent by weight of the APU resin of Example 1. Thus, a 180 percent increase in deposition of CTAB is noted at pH 8.5.

EXAMPLE 3 Example 2 is repeated with the exception that a percent aqueous ethanol mixture is substituted for water in the test solution and the pH is adjusted to 6.5. A deposition value of 202 micrograms of CTAB is noted in the absence of APU resin, and a deposition value of 643 micrograms of CTAB is noted in the presence of 0.73 percent by weight of the APU resin of Example This represents an increase in deposition of about 220 percent. For comparison, only 227 micrograms of CTAB are deposited when the concentration of CTAB in the test solution is increased to 1 percent by weight. Thus, the APU resin is significantly more effective in enhancing deposition than an increase in the CTAB concentration from 0.25 to 1 percent, a 300 percent increase.

EXAMPLE 4 When the procedure of Example 1 is repeated using a 0.5 percent-by-weight aqueous alcoholic dispersion of radioactive (C-l4) bis(3,5,6 trichloro-2- hydroxyphenyl) methane as the test solution, the radioactivity of the gelatin disk averages 2,100 counts per minute (cpm.) Repetition of the test in the presence of 1.25% concentration of the APU resin of Example 1 results in an average radioactivity of 13,200 cpm. Thus, the presence ot the APU resin increases the deposition of the antimicrobial compound by about 500%. Substantially similar results are noted when either lamb skin or human callus tissue is substituted for the gelatin disk in the foregoing experiment.

The APU resin of Example 1 can be replaced by either a resin having a molecular weight of about 4,600 and the repeating unit +Cl-l N (Cl-1 (CI-1 NH- C(O)NH-lor a resin having a molecular weight of about 6,700 and the repeating unit with substantially similar results. Similarly, the substituted methane may be substituted with 5-chloro- 2(2,4dichlorophenoxy) phenol with substantially similar results.

EXAMPLE 5 Tests of the following shampoo illustrate the improved effects attributable to the APU resin. This shampoo is effective to inhibit the growth of Pityrosporum ovale.

In this evaluation, 2.5 grams of shampoo are diluted with 7.5 grams of water to simulate normal use dilution of shampoos, and the diluted shampoo is test solution. Under such conditions, the concentration of zinc 2-pyridinethiol-1-oxide in the test solution is 0.4 percent by weight, and the concentration of APU resin is 0.5 percent by weight. Repetition of the foregoing test with an identical composition not containing APU resin results in the deposition of 8.7 micrograms of zinc 2-pyridinethiol-l-oxide. Thus, use of APU resin in combination with zinc Z-pyridinethiol-l-oxide in the presence of detergents results in an increase in deposition of about percent.

To confirm that increased deposition results in enhanced residual activity, radioactive disks obtained using the foregoing evaluation technique are plated in a standard agar medium inoculated with P. ovale, and the diameters of the zone of inhibition are measured after 24 hours of incubation. These results are shown in Table I together with results of non-radioactive disks. Resin A alone has no zone of inhibition.

Table I Zinc 2 Zone of inhibition pyridinethiol-l-oxide APU resin after 24 hours (m.m.)

The foregoing results indicate that APU resin significantly improves the antibacterial effectiveness of the zinc 2-pyridinethiol-l-oxide. Further, the results show that radioactivity has a minimal effect on the results.

The effect of APU resin on long-standing activity is illustrated by repeatedly transferring the radioactivity disks of Table I to freshly seeded agar plates inoculated with P. ovale for additional incubation periods after measuring the zone of inhibition. Results are set forth in Table II.

These results indicate that the presence of APU resin results in improved antimicrobial effectiveness of the zinc-2-pyridinethiol-l-oxide and longer-lasting effectiveness.

EXAMPLE 6 Example is repeated with the exception that the concentration of zinc Z-pyridinethiol-l-oxide in the shampoo is reduced to 0.4 percent. 17.4 micrograms of zinc 2-pyridinethiol-1-oxide are deposited on the disk. In the absence of the 2 percent of APU resin, 6.1 micrograms of zinc Z-pyridinethiol-l-oxide are deposited on the disk. Again, APU resin significantly enhances the deposit of zinc Z-pyridinethiol-l -oxide on a proteinaceous substrate.

In the absence of APU resin, a halo diameter of 37.5 m.m. is observed. These results show that APU resin improves the effectiveness of the watersoluble sodium Z-pyridinethiol-l-oxide material as well as the water-insoluble zinc-2-pyridinethiol-l oxide.

As only 0.5 micrograms are deposited in the absence of the APU resin, use of the APU resin increases deposit by 200 percent.

EXAMPLE 9 Substitution of 1 percent of trichlorocarbanilide for the tribromosalicylanilide in the composition of Example 8 yields substantially similar results.

EXAMPLE 10 A lotion shampoo composition exhibiting effectiveness against P. ovale follows.

When the foregoing shampoo having a pH of 8.8 is formulated with radioactive 5,7-diiodo-8- hydroxyquinoline (I-l 25) and the deposition evaluated using the procedure of Example 5, the APU resin results in a 220 percent increase in the deposition of the antimicrobial agent. Improved depositionis also obtained when the pH of the composition to 7.8.

When the concentration of 5,7-diiodo-8- 5 hydroxyquinoline is reduced to 1 percent in the composition of Example 10, APU resin achieves a 133 percent increase in deposition of that agent.

The foregoing results show that APU resins improve the brightening effectiveness of fluorescent agents of the anionic type (stilbene disulfonate), nonionic (oxazole) and the cationic type (pyrazoline). The improvement noted in fluorescent varies from 7 to 200 percent.

EXAMPLE 12 The following composition is an improved conditioning shampoo.

The effectiveness of the aminopolyureylene resin in improving the conditioning properties of the protein is shown by the following procedure. A bleached hair tress about 2.5 inches (weight 0.55 grams) is placed in contact with grams of the shampoo composition of Example 12 and the contact is maintained for 30 minutes. The hair tress is then removed from the shampoo, subjected to five consecutive rinses with 55 milliliters of deionized water each time, air dried, and analyzed spectrophotometrically for hydroxyproline. (Hydroxyproline is an amino acid found in hydrolyzed protein, but not in hair.) The protein and aminopolyureylene resin are soluble in the shampoo composition having a pH of 7.5 and the test results for the composition are set forth in Table IV.
