Definitions

• Microbicidal hairdressing compositions which are effective against bacteria and fungi, such as those normally present on the human hair and scalp, comprise an alkyl di-lower alkyl arylalkyl ammonium saccharinate, such as a higher alkyl di-methyl benzyl ammonium saccharinate, a hydrophilic oil and a hydrophobic oil, both of which are ethers of poly-lower alkylene glycol(s) and lower alcohol(s), and an aqueous or aqueous alcoholic medium.
• the described hairdressings are useful in mentioned proportions to make clear liquid or gel preparations. They groom the hair, giving a desirable lustre and facilitating the restyling or combing thereof. They also counteract the growth of bacteria, fungi, yeasts and other microorganisms, such as Pityrosporum ovale, without objectionably depositing opaque coatings on the hair.
• the present invention relates to transparent hairdressings possessing hair conditioning properties as well as the ability to inhibit the growth of Pityrosporum ovale. These preparations, when applied to the hair and scalp, make the hair more readily controllable and easily combed into place.
• the products are especially useful as mens clear hairdressings but may also find applications in clear preparations for the treatment of womens hair.
• a hairdressing comprises minor proportions of antimicrobial higher alkyl di-lower alkyl arylalkyl ammonium saccharinate and hydrophobic and lipophilic lower alkyl monoethers of poly-lower alkylene glycols, in an aqueous or aqueous alcoholic carrier medium.
• such hairdressing compositions are clear liquid or gel preparations and preferably comprise higher alkyl (C C di-methyl benzyl ammonium saccharinate, a hydrophilic polyethylene-polypropylene glycol monoether of butanol which is of molecular weight from about 1,400 to 1,600 and is derived from equal parts by weight of propylene oxide and ethylene oxide and a lipophilic polypropylene glycol monoether of butanol which has a molecular weight of about 2,000-2,500, in a carrier medium which is aqueous ethanolic.
• antimicrobial uses of the composition of higher alkyl di-lower alkyl arylalkyl ammonium saccharinate and the mixed polyalkylene glycol ethers are also within the invention.
• the antimicrobial saccharinates employed are those of the formula wherein R is higher alkyl, A and R are lower alkyls, and n is from 1 to 4.
• R groups which may be employed are the higher alkyls of 8 to 20 carbon atoms, preferably the straight chain alkyls of 10 to 18 carbon atoms, e.g., myristyl, lauryl, decyl, palmityl and stearyl. Of these, the tetradecyl (myristyl) and dodecyl (lauryl) are most preferred.
• such higher alkyls are obtained from mixtures comprising also minor proportions of other higher alkyls, such as palmityl.
• R and R are of l to 4 carbon atoms, preferably of l to 2 carbon atoms and most preferably are both methyl. However, it is not required that R and R; be of the same carbon content.
• the alkylene group, the number of carbon atoms of which is designated by n, is lower alkylene of 1 to 4 carbon atoms, preferably of 1 to 2 carbon atoms and most preferably, is a methylene carbon atom.
• the aryl group although it may include other aromatic rings, such as naphthyl or substituted phenyl, is most preferably phenyl, Thus, the arylalkyl group is most preferably benzyl. Nevertheless, equivalent compounds may be employed wherein the aromatic ring, the alkyls, the alkylene and the saccharinate ring are suitably substituted with non-interfering substituents, such as lower alkyl, halogen, nitro, amino or hydroxy groups. If such substitution is present, it will usually be on the aromatic ring or the higher alkyl, R.
• the antimicrobial saccharinate should be strongly microbicidal, especially efiective against Pityrosporum ovale, and it should be compatible with the other constituents of the hairdressing compositions, especially with the polyalkylene glycol ethers, alcohol, water and gelling agent, if present to form clear solutions or gels.
• the saccharinate should be substantially soluble in the carrier or solvent medium. It must not cause clouding or creaming of the hairdressing.
• the mixed polyethylene-polypropylene glycol ether hydrophilic oil component of the present preparations is one in which the proportions of polyoxyethylene and polyoxypropylene are such that the hydrophilic properties of the product predominate, making it water soluble, while still giving it the thickness and lubricity of an oil. Because the polyethylene glycol or polyethylene oxide component employed to produce the polyoxyethylene portion of the hydrophilic oil is that component which usually favors hydrophilic characteristics, to increase such properties an increase in polyethylene glycol or polyethylene oxide monomer may be effected.
• the proportion of polyoxypropylene or, in some cases, polyoxybutylene can be increased, with greater lipophilic effects being obtained from using the higher polyoxyalkylene, such as polyoxybutylene, due to its increased carbon/oxygen ratio.
• the lipophilic or hydrophilic properties of the polyalkylene glycol and its solubilites are also related to chain lengths or molecular weights and these factors, with ethylene oxide-propylene oxide ratios and etherifying monohydric alcohol carbon contents, are chosen to botain the desired hydrophile-lipophile balance and water solubility for the hydrophilic oil.
• the various polypropylene glycol or polyoxypropylene alkyl ethers are mixtures of polymers of various chain lengths, as are the hydrophilic polymers previously discussed.
• the chain lengths and the chain terminating compound are chosen so that the product will be desirable lipophilic, oily and clear.
• the polymers should be soluble in the alcohol or aqueous alcoholic media employed. Solubility in water itself may be very small, often being less than 2%.
• mixtures of polyoxypropylene butyl monoethers are used.
• the described compounds are known and methods for their manufacture are given in US. Pat. 2,448,664 at columns -8 and in the working examples. This patent describes the useful class of the lipophilic polymers and a similar description, with respect to the hydrophilic polymers, is found in U.S. Pat. 2,425,755, previously cited.
• Preferred blends of glycols or lower alkylene oxides to make the present hydrophilic oils are blends of polyethylene oxide and polypropylene oxide or the equivalent glycols, which contain from 25 to 75% of the polyethylene glycol and 75 to 25%, of the polypropylene glycol or equivalent oxides, preferably 40 to 60% and 60 to 40%, respectively, exclusive of the etherifying chain terminating radicals.
• the polymers made are preferably terminated with hydroxyl or alkyl groups of 1 to 8 carbon atoms, preferably a lower alkyl of from 3 to 5 carbon atoms. Usually the polymers will be terminated at one end with an OH and at the other with a normal alkyl.
• the molecular weights should be regulated to average in the range of about 400 to 4,000, preferably from 1,000 to 2,000 and most preferably from 1,400 to 1,600.
• the chain terminating monohydric alcohol is usually of l to 8 carbon atoms and is linear. Preferably, it is of 3 to 5 carbon atoms.
• the molecular weight of the lipophilic oil is normally within the range of 400 to 4,000, preferably from 1,500 to 3,000.

• glycols or glycerol may be used for this purpose.
• Polyoxylower alkylene glycols of the Carbitol and Pluronic types may be used, as may similar compounds of equivalent properties. Generally, however, these will constitute only a minor proportion of the oil content of the clear, microbicidal hairdressing.
• the aqueous carrier or solvent employed for the microbicidal saccharinates and the hydrophilic and lipophilic oils and adjuvants is usually water, alcohol, or a solution of lower alcohol in water. It will usually be desirable to maintain the hardness of the water under 150 parts per million and waters having hardness equivalents, in terms of calcium carbonate, below 50 ppm. and preferably below 20 p.p.m., are most desirably employed. Of course, the solvent system should be clear and free of suspended matter or other impurities which might undesirably affect the clarity or color of the product.
• the lower alcohols used will normally be either ethanol, which is preferred, or isopropanol, although minor proportions of n-propanol, n-butanol, isobutanol or tertiary butanol can be present.

• a gelling agent is employed to thicken and set the dressing into gel form.
• Many such thickening agents are known in the cosmetic arts, including both organic and inorganic thickeners.
• Useful gelling agents form hairdressings that are clear and generally organic gums or thickeners will be employed.
• Useful colloidal organic thickeners include the carboxyalkyl celluloses, the hydroxyalkyl celluloses, carboxypolymethylenes, (Carbopols) and the various natural gums.

• Especially useful thickening agents which yield clear gels are carrageenan gum, polyvinyl alcohol, polyvinyl pyrrolidone and the ethylene maleic anhydride copolymers, such as Copolymer No. 11 (Monsanto Corp.).
• adjuvants may be present in the hairdressings. Included among such adjuvants are colorants, perfumes, buffers or pH regulating chemicals, antioxidants, ultraviolet ray absorbers, stabilizers and supplementary microbicides.
• the coloring agents and perfumes which are used are standard water or alcohol soluble materials which do not cloud or form films in the present compositions.
• Ultraviolet light absorbers e.g., 2,2',4,4'-tetrahydroxybenzophenone, may also be employed to stabilize color and perfume both in the product and during use.
• the proportions of the various constituents of the hairdressings are maintained within desired ranges to produce the best product.
• the antimicrobial higher alkyl di-lower alkyl ammonium saccharinate generally comprises at least 0.1% of the final product while more than 5% is usually unnecessary. Within the 0.1 to 5% range, a preferred concentration is 0.3 to 1%.
• the Water insoluble polyethylene-polypropylene glycols are used to increase the conditioning properties of the hairdressing, and, because their structure is so similar to that of the hydrophilic oil present, this can be done readily Without creating unstable products, emuls ons or hairdressings which tend to separate.
• the proportions of hydrophilic and lipophilic glycol ethers will be such that from 40 to 95% of the polyalkylene glycol content will be of the hydrophilic oil type.
• the hydrophilic oil should constitute a major proportion, usually from 80 to 100% and preferably from 90 to 95 of the mixture.
• gels are made, from 40 to 60%, preferably about 50% of hydrophilic glycol will be used.
• Exemplary of the lipophilic alkylene oxide random copolymers which may be employed in suitable compositions are Ucons manufactured by Union Carbide Corp. and identified as LB-65, LB-ll45, LB-1715, LB-3000, LB70X, LB- 400X and LB1800X.
• the characteristics of these products, including specific gravities, viscosity indexes, viscosities at 100 F., pour points and flash points are given in Table IV-22 at page 232 of the text Polyethers, Part I, edited by N. Gaylord and published in 1963 by Interscience Publishers.
• the water soluble hydrophilic oil is present in minor proportion, generally from 0.5 to and preferably from 5 to 25% of the product.
• the water insoluble polyalkylene glycol may comprise from 0.5 to 15% of the preferably from 1 to 8% thereof. From 1 to 4% is preferably present in liquids and from 4 to 8% in the gels.
• the carrier or solvent medium of the hairdressing may constitute the balance of the product if no thickeners and/ or other adjuvants are present.
• the water or aqueous alcoholic medium which is often used instead will constitute a significant proportion of the hairdressing, usually being from 40 to 98.9% thereof, with a major proportion, 50.1 to 90% being preferred.
• a gel hairdressing When a gel hairdressing is made, it will normally contain from 0.3 to 5% of an organic gelling agent to thicken the composition. Small proportions, from 0.1 to 0.4% of such products may be employed to increase the viscosity of a liquid hairdressing.
• the thickening effect is dependent on the particular gelling agent being used and the composition being thickened.
• hydrophilic oils and the microbicides of this invention are compatible with the other constituents which may be employed to thicken liquid preparations or to make gels. They are also compatible with the usual adjuvants employed for hairdressings.
• the hydrophilic oil gives body to the liquid hairdressings, compensating for the thinning effects of alcohol and water.
• the alcohol helps to solubilize the various contituents, as does the water, and improves the evaporation rate of the product so that the hair returns to a dry, lustrous state soon after application of the hairdressing.
• a hairdressing can be intentionally made opaque or can be formed into an emulsion or cream, according to known techniques, it is most frequently desired that modern hairdressings leave no creamy 0r greasy deposit on the hair and it is usually important that the product, as applied, should appear to be transparent.
• Most of the various effective microbicides, useful against fungi and bacteria found on the hair are insoluble in conventional hairdressing compositions and in the present oils. Accordingly, their use is limited to opaque lotions or creams.
• hydrophilic and lipophilic polyethylene-polypropylene glycol oils or monoether derivatives thereof result in improved hair conditioning properties, while still maintaining the microbicides effects. This is somewhat unexpected because the hydrophilic oils appear to possess no antimicrobial activity and the lipophilic oils, alone or in mixture with each other dont inhibit microbial growths. Yet, with the saccharinate microbicides, the disclosed oils appear to increase the effectiveness against Pityrosporum ovale, possibly by enlarging the area over which the microbicide may work.
• compositions contain both hydrophilic and lipophilic oils and preferably include a mixture of the lipophilic oils, such as was previously mentioned herein with one or more of the hydrophilic polyoxyethylene-polyoxypropylene polymers.

No difliculties in formulation are encountered and a clear liquid product results.
• the product When applied to the hair in usual quantities, about two to five cubic centimeters per application of 2 to 5 grams per day, the product has a microbicidal action against Pityrosporum ovale, due to the presence of the alkyl dialkyl arylalkyl ammonium saccharinate, in combination with the hydrophilic oil (Ucon 50-HB660). Such ac tion is also observed when the product is applied to other sites of microbial growths.
• the hairdressing also acts to condition the hair, making it easy to comb and giving it a lustre during and after application. It also improve manageability of the hair on remoistening hours after application of the hairdressing.
• the conditioning effect of the composition is still obtained and the hair is not dulled by a coating on the hair of a layer of the composition, which stays transparent on the hair. Conditioning effects are further improved by thep resence of the lipophilic type oils in the products, in addition to the effects obtained from the hydrophilic oils.
• a liquid hairdressing of the above formula is made by substantially following the method of Example 1, sequentially mixing, with stirring, the formula amounts of ethanol, ultraviolet ray absorber, saccharinate, Ucons, perfume, water and colorants at approximately room temperature.
• the product produced is a clear liquid having a specific gravity of about 0.9, a pH of about 6, an alcohol content of 50% by weight and a content of microbicidal saccharinate of 0.5%. If necessary, pH adjustment may be effected by addition of 50% aqueous citric acid solution or a 19.1% Na O caustic soda solution.
• the product made has bactericidal and fungicidal properties but is inferior to the hairdressings of this invention containing a hydrophilic Ucon or equivalent hydrophilic polyoxyalkylated oil because of a tendency buildup of oil and a development of stickiness on the hair with continued applications.
• hydrophilic Ucon oils such as Ucon 50- HB-660, Ucon 50-HB-55, Ucon -H-1400 are added, in amounts from 2 to 8%, e.g., 5%, alone or in mixture
• the applied hairdressing becomes more hydro hilic in nature and is more readily distributed over the hair when the hair is wetted and combed, and undesirable buildup and stickness are decreased.
• Such results are also obtainable when the combinations of hydrophilic and lipophilic oils are employed at lower total proportions, with totals of about 1 to 45%, preferably about 5-15% being preferred, and with a major proportion of the oil content preferably being hydrophilic.
• hydrophilic oil such as Ucon also aids in maintaining the product clear in the bottle as well as after application to the hair.
• the conditioning effects obtained are surprising, considering that the hydrophilic Ucons are much less hygroscopic than other water soluble poly carriers, such as polyethylene glycol, polypropylene glycol, glycerol and sorbitol.
