Description

The invention relates to a hair conditioning agent and a method for producing a hair co-conditioning agent. This agent may be in the form of a shampoo, which contains liquefied polyethylene and which improves the condition of the washed hair (after washing, it is easier to comb, more elastic and has a lower static charge).

Grain co-treatment agents, such as laundry treatment agents that contain fabric softeners, co-specialize the washed fabrics by making them soft and reducing the likelihood of static charge retention after drying in an automatic laundry dryer. These agents contain cationic conditioning agents such as quaternary ammonium halides, which are also found in hair rinses. Polyethylene has also been used in the treatment of fibrous materials, including human hair, sometimes as a lubricant for these materials. Mineral oil was also used as a lubricant and as a polishing agent for the hair, including the hair. Such substances were also included in shampoos, some of which were based on anionic synthetic organic detergents.

It is not apparent from the prior art, however, that a liquid hydrocarbon such as a mineral oil could be used in the presence of a cationic surfactant to dissolve or liquefy a normally water-insoluble polyethylene before desperating it in water, and that such a de-parietal polyethylene is the presence of a cationic surfactant for drug co-selection would greatly improve the co-selection of hairy materials, especially human hair, when treated with such an anionic synthetic organic detergent shampoo.

According to the invention, the hair conditioner comprises quaternary ammonium selenium as a co-agent, a water-soluble anionic synthetic organic surfactant, and a water-insoluble polyethylene and a polyethylene solubilizer which makes it dispersible in water in the presence of a quaternary ammonium salt which is liquid in under normal conditions a hydrocarbon or a mixture of hydrocarbons and contains water. The dispersed polyethylene significantly increases the co-mediating effect of the cationic surfactant of the co-agent.

Preferred quaternary ammonium salts are represented by the formula R ¹ R ² R ³ R ⁴ n + X " ¹ , wherein at least one R is lower alkyl and at least higher alkyl, and the rest

165,297 are higher and / or lower alkyl. Preferably R ¹ is lower alkyl of 1 to 4 carbon atoms, R ² and R ³ are higher alkyl of 10 to 40 carbon atoms, R ⁴ is lower or higher alkyl, and X is a salt forming anion such as a halide anion , alkanolsulfate lower or carboxyl lower, e.g. chloride, bromide, methosulfate, ethosulfate or acetate. Lower alkyl usually contains 1 to 3 or 4 carbon atoms, preferably 1 or 2 carbon atoms, more preferably methyl, and higher alkyl contains 10 to 40 carbon atoms, preferably 12 to 18.20 or 22 carbon atoms, especially 14 or 16 to 18 or 22 carbon atoms, e.g. 16 or about 16.

The anion is preferably a halogen such as chlorine, bromine or iodine, with chlorine and bromine being preferred, especially chlorine.

Preferably there are 1 or 2 lower groups and the higher alkyl groups usually 2 or 3.

It has been found that the total number of carbon atoms in the quaternary ammonium salt should be at least 30, preferably at least 34 carbon atoms, and most preferably the quaternary ammonium salt should contain three higher alkyl groups and one lower group and be chloride. Most preferably the higher alkyl is methyl, most preferably the lower alkyl is methyl and the most preferred quaternary ammonium halide is tricetylmethyl ammonium halide. However, the composition of the invention may contain other quaternary ammonium halides such as distearyl dimethyl ammonium chloride, dilauryl methyl ammonium bromide, stearyl cetyl dimethyl ammonium chloride.

The second conditioning component of the compositions according to the invention is normally solid, water-insoluble polyethylene. Such a polymer has a solubility of less than 0.1 g / 100 ml of water. In an aqueous environment, even if it is in a very finely divided form, it conditions little fibrous materials such as human hair that are treated with such aqueous compositions and exhibits similarly low conditioning activity in other environments that may be used to condition materials fibrous. However, in the composition of the invention, when used together with a normally liquid hydrocarbon such as mineral oil, the water-insoluble polyethylene is activated in combination with a cationic surfactant that is also a component of the agent, surprisingly increasing the conditioning effect of such a cationic conditioning agent. conditioning.

The polyethylenes used in the compositions according to the invention usually have a molecular weight in the range of 1,000 to 5,000, preferably 1,000 to 4,000, more preferably 2,000 to 2,500, and most preferably 2,000 or 2,100 or about 2,000. carboxyl end groups. Such polymers, especially the most preferred ones, will disperse in an aqueous medium containing detergents in the presence of a fluidizing amount of mineral oil or other relatively low molecular weight (usually liquid) hydrocarbon or an equivalent poly-lower alkylene solubilizer.

A polyethylene solubilizer is a substance that renders it water-dispersible in the presence of a cationic surfactant and water and in the presence of an anionic synthetic surfactant or detergent. By using the solubilizer, the normally solid water-insoluble polyethylene is pulped so that it can be dispersed and form an aqueous suspension in which no phase separation or settling of the polymer occurs. The presence of the solubilizer also surprisingly improves the conditioning performance of the cationic surfactant significantly, possibly due to the enhanced performance of the second conditioning agent. The solubilizer is preferably a hydrocarbon which is normally liquid and normally has a molecular weight in the range 150 to 1000, preferably 300 to 800, more preferably 400 to 700 and most preferably 500 to 600, e.g. 550 or about 550.

The hair conditioner may take various forms and may be used in various applications. It is preferably liquid, often in an aqueous medium, but may also be used in other useful forms. It may be in the form of a gel, paste, cream, foam or aerosol, it may even be in the form of a solid (rod) and then it may be dispersed in water or

165 297 other aquatic medium at the time of use. Preferably the agent of the invention is in the form of a shampoo, which will typically include a synthetic organic detergent such as an anionic detergent and water. Instead of an anionic detergent, amphoteric, ampholytic, zwitterionic and nonionic detergents and surfactants can optionally be used in such shampoos. Such various suitable detergents are mentioned in McCutcheon's "Detergents and Emulsifiers, North American Edition, 1964.

Preferred anionic detergents also described therein can be referred to as "sulfonated or" sulfated. " They are water-soluble lipophilic sulfates and / or sulfonates of 8 to 22 carbon atoms, preferably 8 to 18 carbon atoms, more preferably 10 to 16 to 18 carbon atoms, and most preferably 12 to 16 or 18 carbon atoms. Among such anionic detergents, mention may be made, for example, of higher alkyl sulfates, paraffin sulfonates, olefin sulfonates, sulfated monoglycerides, sulfated lower alkyl higher fatty alcohols and linear higher alkyl benzene sulfonates. Most preferred higher alkyl sulfates contain 12 to 16 carbon atoms and most preferred higher alkoxylated alkyl sulfates contain 16 to 18 carbon atoms, with the higher alkyl being lauryl and containing 2 or 3 ethoxy groups per molecule. However, it may be desirable for the alkyl group to contain 12 to 16 carbon atoms and for the alkoxy group content of the molecule to be 1 to 20, such as 2 to 6 ethoxy groups. Most preferably the sulphated higher fatty alcohol is lauryl sulphate, and a particularly preferred sulphated polyalkoxylated lower alkyl higher fatty alcohol is sulphated di- or triethoxylated lauryl alcohol.

The most preferred anionic detergent is a mixture of a higher alkyl sulfate and a higher alkyl ether sulfate, and the ratio of the amounts of these ingredients is typically in the range 10: 1 to 1:10 or 7: 1 to 1: 7, e.g. 1: 5 and 5: 1. Anionic detergents are used in the form of their water-soluble salts, which are typically the salts of alkali metals (e.g. sodium, potassium), ammonia, amines (such as dimethylamine and trimethylamine), or lower alkanolamines (such as triethanolamine, diethanolamine and monoethanolamine). Examples of such detergents are ammonium lauryl sulphate, sodium diethoxylated lauryl sulphate, ammonium triethoxylated lauryl sulphate, sodium alpha-C-E olefin sulphonate, sodium C14 paraffosulphonate, sodium sulphated monoglyceride coconut oil, triethanolamine sulphate salt salt of dimethylamine and myristyl sulfate. However, the best results are obtained by using higher alkyl sulfates or a mixture of higher alkyl sulfate and higher alkyl ether sulfate, such as a mixture of diethoxylated or triethoxylated lauryl sulfate and lauryl sulfate with more higher alkyl sulfate and with ammonium or triethanolamine salt and anionic detergent also in larger amounts.

In aqueous compositions of the invention, including preferably shampoos, deionized water is preferably used with a hardness of less than 10 ppm based on calcium carbonate, but other types of water may also be used as appropriate. In order to protect the composition according to the invention against microorganisms, it is preferable to use irradiated deionized water, and the used mixers, tanks and pipelines should be kept absolutely clean.

In addition to the necessary ingredients, the conditioning compositions and shampoos, which are a preferred form of the compositions according to the invention, may also contain various known excipients which impart the desired properties to the compositions. Such substances include paraffins, petroleum jelly, microcrystalline waxes and isoparaffins (all of which can act as solubilizing hydrocarbons in addition to mineral oil), esters of higher fatty acids and lower alcohols, esters of lower fatty acids and higher alcohols, and esters of higher fatty acids and higher alcohols, such as those described in US patent application SN 07 / 369,361, thickened such as lower alkylcelluloses and resins such as xanthan gum, which may also act as stabilizers, modifiers and foaming agents such as betaines, higher fatty acid triglycerides and lower alkanolamides, e.g. coconut oil amidopropyl betaine , triglycerides of C1a-3e acids and lauryl monoethanolamide, a pearlescer such as ethylene glycol mono- and distearate, complementary conditioning agents such as silicones and amine-substituted silicones, anti-dandruff agents such as pyrithione, viscosity regulating agents such as propylene glycol sodium chloride, preservatives and antioxidants, anti-freeze agents such as ethylene glycol, sequestering agents such as EDTA, pH adjusters such as citrates and citric acid, colorants (dyes and dispersing pigments), and solvents such as ethanol and isopropanol.

The compositions according to the invention contain the individual ingredients in such amounts as to produce the desired markedly increased conditioning effect. Such an improvement in conditioning performance is obtained when the amount of cationic fiber conditioning surfactant is a conditioning amount and the amount of normally solid water-insoluble polyethylene is sufficient for the water dispersed polyethylene to increase the conditioning performance of the cationic agent and the amount of hydrocarbon or hydrocarbon mixture in the liquid state is one that can help to liquefy the normally solid polyethylene and make it water-dispersible in the presence of the said amount of quaternary ammonium salt and water. In conditioning agents and shampoos that contain an anionic synthetic organic detergent, it is used in an amount that provides surface-active properties, and often in a detersive amount, depending on the intended use. The amount of water should be sufficient to create a continuous environment as with a shampoo.

Shampoos typically contain the following ingredients: lipophilic sulfate and / or sulfonate in the range of 8 or 10 to 25.30 or 35%, preferably 8 to 20%, more preferably 10 to 15% of sulfated alcohol or sulfated alcohol ether and 1 to 5%. % alcohol ether sulfated or alcohol sulfate, especially 10 or 11 to 13 or 14% alkyl sulfate and 1 to 4% alkyl ether sulfated, e.g. 12.5% ammonium lauryl sulfate and 2.5% sodium lauryl sulfate diethoxylated. The amount of cationic hair conditioner or quaternary ammonium salt is usually in the range 0.1 to 3%, preferably 0.2 to 2%, more preferably 0.3 to 1 or 1.5%, even more preferably 0.3 to 0.7 and most preferably 0.4 to 0.5%, e.g. about 0.5%. Normally solid polyethylene content is usually in the range 0.1 or 0.2 to 5%, preferably 0.2 to 1.5 or 2%, more preferably 0.2 or 0.5 to 1% and usually most preferably 0.3 or k0.5 to 0.9% e.g. about 0.4 and 0.75%. The mineral oil content is usually in the range 0.1 to 10%, preferably 0.1 to 8%, more preferably 0.5 to 6%, and most preferably 0.7 to 5%, e.g. about 1% or about 4%. The total excipient content is usually in the range 0.1 to 30%, preferably 0.5 to 20% and more preferably 3 to 15%. The water content is in the range of 50 to 95%, preferably 50 or 70 to 90%, most preferably 65 to 80%, e.g. about 73%.

The ranges of the amounts of the various excipients or other ingredients which are not required in the composition of the composition according to the invention and which may be present together or in different combinations are as follows: 0.1 to 2%, preferably 0.1 to 1%, more preferably 0 , 1 to 0.5%, e.g. about 0.25% or 0.3%, isoparaffins of 10 to 18 carbon atoms, preferably 12 to 16 carbon atoms, more preferably 13 to 14 carbon atoms; 0.1 to 2%, preferably 0.1 to 1%, more preferably 0.1 to 0.5%, e.g. about 0.35% or 0.4% of paraffins with 20 to 60 carbon atoms, preferably 20 to 50 carbon atoms and more preferably 20 to 40 carbon atoms: 0.05 to 1.5%, preferably 0.2 to 1% and more preferably 0.4 to 0.8%, e.g. about 0.6% of the cellulosic thickener which is preferably hydroxyalkyl cellulose or a mixture of hydroxyethyl celluloses; 0.5 to 6%, preferably 2 to 5%, more preferably 2 to 4%, e.g. about 3.5% of the lower alkanolamides of higher fatty acids (where the higher fatty acid contains 12 to 18 carbon atoms and the lower alkanol 2 to 3 carbon atoms), preferably higher fatty acid monoethanolamide, and more preferably lauric or lauric myristic acid monoethanolamide; 0.5 to 1.5%, preferably 0.5 to 1%, more preferably 0.7 to 0.9% e.g. about 0.8% of a higher fatty acid lower alkylene glycol ester, preferably a higher fatty acid diester ethylene glycol , such as ethylene glycol distearate; 0.1 to 1%, preferably 0.1 to 0.6%, more preferably 0.2 to 0.5%, e.g. about 0.4% higher fatty acid ester of higher fatty alcohol, preferably C 12-18 acid ester and a C12-18 alcohol, more preferably an ester of a C 1-8 fatty acid and a C16-18 alcohol, e.g. stearyl stearate; 0.3 to 2%, preferably 0.5 to

* Hair conditioning agents, in order to be commercially available, must be chemically and physically stable (especially they should not lose their improved conditioning properties), should not delaminate, solids cannot settle in them, and their viscosity must not change inappropriately . The shampoos of the invention have a viscosity in the range 1000 to 15000 mPa · s at room temperature (25 ° C), preferably in the range 3000 to 6000 mPa · s, and more preferably 3500 to 4000 mPa · s at such temperature. The shampoo of the invention can be stored without solids settling and substantially retaining the improved conditioning properties of the hair. Also, the viscosities remain the same as when they were made, with some predicted increase just after completion of manufacture, and the desired in-use viscosity of the product can also be roughly planned.

The improved conditioning ability of the hair compared to the control formulations, which did not contain polyethylene and mineral oil, is noticeable to the casual shampoo user. This ability is measured in standard tests by ease of wet combing, ease of dry combing, styling payments, and static charge maintenance (related to undesirable scattering of hair).

The incidental user may find that after treatment with the inventive shampoo, the hair is easier to comb, both wet and dry, than with the control formulation, and that the hair is more manageable and less prone to static charge build-up and undesirable scattering. . Scientific tests also confirm that the force required to move the comb in the standard route after treatment with the conditioner composition or shampoo according to the invention (and after rinsing) is lower than in the control. Also, the scattering of the hair is significantly lower than when the control product is used for the treatment of hair. These results are confirmed by panel tests, in which a panel of experienced persons assesses combability, static charge and drapeability in a blank test in which the control agents according to the invention are used.

The compositions and shampoos of the invention are used in the same way as known hair conditioning compositions and shampoos. Conditioning agents may be used at room temperature or slightly above in normal amounts, and may be left on the hair for a varying amount of time depending on the degree of conditioning desired. Typically, the temperature of the conditioner and the hair is in the range of 15 to 50 ° C, preferably 20 to 40 ° C, and the conditioner is in contact with the hair for 30 seconds to 10 minutes, preferably 1-5 minutes. The amount of agent used will typically be in the range 0.1 to 25 g, often 0.2 to 10 g, more usually 0.5 to 2 g for the non-aqueous and non-solvent (non-alcohol) ingredients. The shampoo may be used in an amount in the range of 0.5 to 50 g, often 2 to 15 or 20 g, and more usually 5 to 10 g. The applied composition can be applied to the hair with a brush or comb, then rinsed or left on the hair or partially. remove with a towel. When the shampoo is used to wash and condition your hair, rinse it with water after keeping it in the form of a watery foam for a sufficient time, usually 1 to 5 minutes, to obtain a satisfactory condition, after which you can wet comb, blow-dry the hair with a dryer , comb or dry brush for a suitable hairstyle.

According to the present invention, a method of making a hair conditioner comprising a conditioning amount of a quaternary ammonium conditioner, a surface active amount of a water-soluble anionic synthetic organic surfactant, a water-insoluble polyethylene in an amount sufficient to enhance the conditioning effect of a quaternary ammonium salt when solubilized and a solubilizing amount of a liquid hydrocarbon under normal conditions or a mixture of hydrocarbons that solubilize polyethylene and water comprises the following steps: (a) preparing a dispersion or emulsion of said anionic surfactant in water at elevated temperature, (b) preparing a quaternary salt solution or dispersion ammonium conditioning hair and polyethylene in said liquid hydrocarbon solubilizing agent at elevated temperature; and (c) mixing the premix of (b) with the suburb glass from step (a) to form a stable dispersion or emulsion.

According to the invention, the method of making a hair conditioner in the form of a shampoo and with very good storage and use stability is to prepare a dispersion or emulsion in water of a water-soluble lipophilic sulfate and / or sulfonate and excipients at elevated temperatures, such as 90 ° C, dissolving and / or dispersing a cationic conditioning agent such as a quaternary ammonium halide with a normally solid polyethylene in a liquid mineral oil at elevated temperature (70 to 90 ° C) and mixing the two solutions and / or dispersions to produce permanent dispersion. When auxiliary substances are used, those soluble and / or dispersible in water can be mixed with substances in the aqueous phase, and those insoluble and non-dispersible in the aqueous medium, such as paraffins, isoparaffins and microcrystalline wax, can be mixed with the three lipophilic substances mentioned or in some in cases they can be added to a mixture of aqueous and lipophilic substances, before or after cooling them to room temperature. Typically, flavorings are added to the other blended ingredients after cooling to prevent volatilization or degradation upon heating. When the above-mentioned conditions are not followed, i.e. when the ingredients are freely mixed, the product may become unstable and separate, or solids may settle. Such unstable compositions have poorer conditioning properties than the stable compositions and shampoos which are made by the process of the invention.

The conditioning composition of Formulation A as above is prepared by heating the water-soluble and dispersible components together with all or substantially all of the water (if some water is used in this step, the rest is added to a mixture of heated water of the part and heated lipophilic molten or dispersed substances). ), heating polyethylene, mineral oil, paraffin wax, and hydrocarbons of other "liquid hydrocarbons" together to a temperature of about 80 ° C, and mixing the heated premixes with stirring for 10 minutes. A stable shampoo is obtained which does not separate and from which solids do not settle after a month of storage at elevated temperature, which corresponds to a storage of at least one year at room temperature. The resulting shampoo is tested for conditioning properties by a team of at least 5 experts who evaluate the conditioning effects. The effect of such a composition is tested on hairpieces and / or on live hair which is washed with this shampoo, rinsed with water and dried. Hair condition is assessed for various conditioning characteristics, including ease of wet and dry combing, static charge, loose hair and manageability.

A similar method is used to prepare the control shampoo (B), which has the same composition as shampoo A, except that it does not contain polyethylene and mineral oil, which are replaced with water. Both compositions have a pH of approximately 6.5 and a viscosity at 25 ° C of about 3500 or 4000 mPas. A team of skilled artisans evaluate hairpieces washed with this control shampoo, rinsed and dried in the same way as for composition A. both compositions. All the conditioning effects obtained with Composition A were found to be significantly better than with Composition B.

The other trade names of ingredients are explained in Example I.

A shampoo of the above composition is prepared in the same manner as that of Example 1, and the melt of lipophilic substances includes polyethylene, mineral oil, paraffin wax and isoparaffins. The shampoo produced has a pH of about 6.5 and a viscosity of about 3500 or 4000 mPa · s at 25 ° C, is stable, maintains its initial improved conditioning properties, does not separate, settle, or otherwise deteriorate in storage for up to one year.

Tested with a control shampoo with the same composition but not containing polyethylene, it has much better co-conditioning properties, which were assessed on the basis of complete ease of wet and dry combing, greater ease of styling, less electrostatic charge, less scattering in the hair in tresses, which were washed with these shampoos.

In the composition of the above shampoo, anionic detergents can be changed, their amounts can be modified, and hair co-conditioning agents can be added, but it has been found that the presence of polyethylene, solsbilidated with mineral oil, clearly improves the conditioning properties of the shampoo.

The inventive products of Examples 1 and 2 represent a significant improvement over known conditioning shampoos of this type, mainly due to the presence of a lower polyalkylene co-modifying agent in them in combination with a mineral oil and a cationic co-acting surfactant. Conditional differences are not only noticeable during instrumental testing or by observing professionals, but are also obviously noticeable by the average user of these products. The hair treated with the shampoo according to the invention is apparently easier to comb wet and to brush and dry combed. They are easier to arrange, at least in part because of the lower static charge they build up on them, and because the hairs less tend to repel each other, resulting in undesirable scattering of the hair.

When the composition according to the invention is modified by changing various of the essential ingredients, as defined in the examples, to other ingredients mentioned herein, such as, for example, replacing anionic detergents with a salt of triethanolamine and lauryl sulfate; sodium salt of myristyl sulphate, potassium salt of cetyl sulphate, salt of trietaolamiey and diethoxylated myristyl sulphate, sodium salt of C14 paraffin sulphonate, ammonium salt of C10 olefin sulphonate or salt of trietaeolamide and monoglyceride sulphate from coconut oil or polyethylenes with higher molecular weight or with other polyethylenes mixtures, such as polyethylene 6A, 7A, 8A and 725 from Allied®ignal AC and polyethylenes E-12, E-14 and E-43 (with molecular weights 1800,2300 and 4500) from Eastman Chemical Corporation, then mineral oil replaced with mineral oils with molecular weights of about 550 or more to 1000 or less to 150 or by replacing the cationic surfactants, at least in part, with distearyldimethylammonium chloride, trilaurylmetelammonium chloride, stearylcetyl dimethyl ammonium chloride or dilauryl demethyl ammonium chloride, the desired hair-cleaning and co-cleaning effect is also obtained is even greater when the composition comprises a combination of polyethylene and mineral oil. Various or some of the illustrated excipients can also be included in such compositions. Advantageously, in addition to or in lieu of other optional conditioning agents mentioned, the compositions may contain amieosiliko, such as those described in US Patent Nos. 4,559,227, 4,563,347, 4,601,902, 4,704,272, and 4,749,732.

Preferably such an aminosilicone hair conditioner is present in the shampoo in an amount of 0.05 to 3%, most preferably 1 to 2%. The quantitative composition of the various co-conditioning compositions can vary, the contents of the ingredients can be increased or decreased by 10%, 20% and 30%, and an improved conditioning effect is also obtained.
