A fiber conditioning composition, which comprises cationic face-active agent for fibre conditioning, normally solid, water-insoluble polyalkylene and/or oxidised polyalkylene containing in the alkylene part 1 to 5 carbon atoms and solubilizating agent for the said polymer, which causes fluidification of this polymer and its water dispersibility in the presence of this cationic face-active conditioning agent for the fiber and water conditioning, whilst resulting solubilizating polyalkylene markedly increases conditional effect of this cationic face-active agent in fiber conditioning.

Description

COMPOSITION ΝΑ FIBER TREATMENT AND USE

Technical field

The invention relates to a fiber treatment composition and its use. In particular, the invention relates to compositions which are used in the form of shampoos and which shampoo better hair conditioning (hair is more supple, easier to comb and less electrostatically charged).

BACKGROUND OF THE INVENTION

Fiber conditioning compositions, such as compositions for treating laundered fibrous materials, which contain fabric softeners and which treat the laundered fabrics to such an extent that the fabrics are then more flexible and less prone to holding electrostatic charges after drying in automatic laundry dryers include cationic conditioning agents, such as quaternary ammonium halides, these quaternary ammonium compounds also being included in hitherto known hair dressings. Likewise, polyethylene is often used as a lubricant in fibrous materials, including human hair. Mineral oil is also used as a lubricant and also serves as a shiny fiber treatment agent. Similarly, said materials have been added to shampoos, some of which contain anionic synthetic organic detergents as an essential ingredient. However, it is believed that the nature of the invention is novel since it was previously not known that a normal liquid hydrocarbon such as mineral oil could be used in the presence of a cationic surfactant fiber conditioning agent to solubilize or liquefy normally water insoluble ilkylene £

V91 / 94H before dispersing it in water. Thus dispersed as

for example polyethylene, could in the presence of a cationic surfactant to treat textile materials significantly improve the conditioning (conditioning) of fibrous materials, especially human hair, after they have been treated with the hair treatment composition in the form of an anionic synthetic organic detergent shampoo.

SUMMARY OF THE INVENTION

The essence of the fiber treatment composition of the present invention is that it comprises a cationic surfactant conditioning agent, normally solid in water.

and / or an oxidized polymer which makes the polymer liquid and water dispersible in the presence of the cationic surfactant conditioning agent for fiber and water, the resulting solubilized poly (lower alkylene) significantly enhances the conditioning effect of the cationic surfactant conditioning agent in the fiber treatment .

Preferably, the composition comprises a conditioning portion of the quaternary ammonium salt as a fiber conditioning agent, normally solid water-insoluble polyethylene in an amount sufficient to enhance the conditioning effect of the quaternary ammonium salt in the fiber treatment wherein the polyethylene is liquefied to disperse in the water. and a solubilizing fraction of a hydrocarbon or hydrocarbon mixture, respectively; which is a solubilizing agent for polyethylene; which makes it water dispersible in the presence of a quaternary ammonium salt and water.

The present invention also encompasses the use of the above-mentioned fiber conditioning composition comprising a cationic surfactant fiber conditioning agent, a normally solid water-insoluble polyalkylene and / or oxidized polyalkylene alkylene, and a solubilizer for the polymer. liquid and water

V691 / 94H dispersible in the presence of this cationic surfactant conditioning agent to treat fiber and water, to condition the hair.

Accordingly, the present invention provides a fiber conditioning composition comprising a cationic surfactant fiber conditioning agent, a normally water-insoluble poly (6-alkylene) and / or oxidized polyphenylene) and a solubilizing agent for said polysilkylene. this combination makes the polymer liquid and dispersible in water in the presence of said cationic surfactant to treat the fibers and water, and in the treatment of these fibers the presence of the dispersed poly (alpha) alkylene) significantly enhances the conditioning effect of said cationic surfactant fiber conditioning agent. The invention also relates to said compositions which are in the form of an anionic synthetic organic detergent shampoo, as well as to the use of these compositions (and shampoos).

The aforementioned cationic fiber surfactant, which is the primary conditioning agent of the fiber treatment composition, is preferably a quaternary ammonium salt, and other cationic surfactants with fiber conditioning capabilities may also be used, at least of which: section. Accordingly, the imidazoline salts and betaines and the cationic substances described, for example, in U.S. Pat. No. 4,000,077 to replace the above-mentioned ammonium salts, and it is also possible to use complexes of cardboard surfactants with anionic surfactants and organic acids such as citric acid. These complexes are described in U.S. Pat. (Corresponding Patent Application S.N. 06 / 916,067 and U.S. Patent Application Nos. 06 / 916,068 and 06 / 916,069).

Preferred quaternary ammonium salts have the general formula

R ¹ R ² R ³ R ⁴ N ⁺ X 'v691 / 94H in which:

at least one R group is a lower alkyl group and at least one is a higher alkyl group and the others are higher and / or lower alkyl groups. Preferably, R ^{1 is a} lower alkyl group having 1 to 4 carbon atoms, R ² and R ³ are higher alkyl groups having 10 to 40 carbon atoms, R ⁴ is either said higher alkyl group or lower alkyl group, and

X is a salt-forming anion such as a halide, a lower alkanol sulfate or a lower carboxylic acid residue (such as a chloride, bromide, metho-sulfate, etosulfate or acetate).

Said lower alkyl group usually contains 1 to 3 or 4 carbon atoms, more preferably 1 to 2 carbon atoms, more preferably methyl, and the higher alkyl group contains 10 to 40 carbon atoms, more preferably 12 to 18 carbon atoms , 20 or 22 carbon atoms, more preferably 14 or 16 carbon atoms, or 22 carbon atoms, for example 16 or about 16 carbon atoms. The above anion is preferably a halogen such as chloride, bromide or iodide, with chloride and bromide being more preferred, and chloride being most preferred.

The number of lower alkyl groups is preferably 1 or 2 and the number of higher alkyl groups is 2 or 3. It has been found that it is desirable that the total number of carbon atoms in the quaternary ammonium salt be at least 30, and more preferably at least 34, most preferably the quaternary ammonium salt it contains three higher alkyl groups and one lower alkyl group, the salt being the chloride. The most preferred higher alkyl group is cetyl, the most preferred lower alkyl group is methyl, and the most preferred quaternary ammonium halide is tricethylmethylammonium chloride. However, it is within the scope of the present invention to use other quaternary ammonium halides, such as distearyldimethylammonium chloride, dilauryldimethylammonium bromide, stearylcetyldimethylammonium chloride, and other other conditioning cationic surfactants to provide at least a total cationic hair conditioning agent of at least about 60% or surfactant) of the compositions of the present invention.

The secondary fiber conditioning component of the composition is typically a solid water-insoluble poly (lower alkylene). The solubility of this polymer is less than 1 gram / 100 milliliters of water, and often its solubility is less than 0.1 gram / 100 milliliters of water. When present in an aqueous environment, although present in a very finely ground form, the application of these aqueous compositions results in only a minor conditioning effect in fibrous materials such as human hair, and a similarly low conditioning effect when applied other media in which it is contained that are suitable for application to fibrous materials for conditioning purposes. However, in the compositions of the present invention, when the poly (phthalene) alkylene is used in conjunction with a normally liquid hydrocarbon, which may be a mineral oil, the water-insoluble poly (phthalene) alkylene is activated and in conjunction with a cationic fiber surfactant. which is also present in the composition, surprisingly increases the conditioning effects of these cationic conditioning agents in fiber treatment.

although a variety of polyisocyanene polymers such as polymers of hydrocarbons containing from 1 to 5 carbon atoms each may be used as secondary conditioning agents, the molecular weight of these polymers being between 1,000 and 10,000 or more, between whereby a useful enhancement of the conditioning effects of cationic conditioning agents can be realized include ethylene or propylene polymers which can be used behind straight chain polymers based on methylene groups or can be polymers with varying amounts of branches, their molecular weight usually being a range of from 1,000 to 5,000, preferably from 1,000 to 4,000, more preferably from 2,000 to 2,500, and most preferably having a molecular weight of 2,000 or 2,100, or about 2,000. oxidized version of these polyalkylene polymers, such as those which may form larger hydrocarbons having carboxyl end groups. These polymers, especially the most preferred ones, may be dispersed in an aqueous medium which also contains anionic synthetic organic surfactants or detergents when a relatively low molecular weight mineral oil or other hydrocarbon liquid component (usually in the composition) is present. liquid equivalent) or equivalent solubilizing agent (poly (p-phenylalkylene)).

Among the solubilizing agents of the polysilkylene alkylene). include those which render the polymer dispersible in water in the presence of a cationic surfactant to treat fibers and water, and also in the presence of an anionic synthetic organic surfactant or detergent. As a result of the use of the solubilizing agent, the normally solid water-insoluble polyalkylene alkylene is solubilized so that it can be dispersed and remain suspended in an aqueous environment without causing an unpleasant phase separation or polymer shrinkage. It has also surprisingly been found that the presence of a solubilizing agent also significantly improves the conditioning effect of the cationic surfactant in fiber treatment, which is possible due to the increased fiber conditioning effect of the secondary conditioning agent. Preferably, the solubilizing agent is a normally liquid hydrocarbon having a molecular weight of from 150 to 1,000, more preferably from 300 to 800, more preferably from 400 to 700, and most preferably from 500 to 600, for example, 550 or about 550.

The fiber treatment composition can be in any suitable form, and can be used in a variety of treatment applications. Preferably, the composition is in liquid form, many times in an aqueous environment, but can also be used in other suitable forms for various applications. These forms may be gel, paste, cream, foam or aerosol, but may also be used in solid form (stick) and may be dispersed in water or other aqueous medium in this solid form. Preferred compositions of the present invention are shampoos, which typically comprise a synthetic organic detergent, which may be, for example, an anionic detergent, and water.

In these shampoos, amphoteric, ampholytic, zwitterionic or nonionic detergents and surfactants may be used in place of the anionic detergent (s) or may be used simultaneously with the above-mentioned anionic detergent (s). Such suitable detergents are disclosed, for example, in McCutcheon ' s Detergents and Emulsifiers, North American Edition, 1984. Preferred anionic detergents also referred to in this publication may be referred to as sulfonated or sulfated ( _B sulf (on) ated "). These are water-soluble lipophilic sulfates and / or sulfonates containing 8 to 22 carbon atoms, preferably containing 10 to 18 carbon atoms, more preferably 10 to 16 or 18 carbon atoms, and most preferably containing 12 to 16 or 18 carbon atoms. . Examples of such anionic detergents include higher alkyl sulfates, paraffin sulfonates, olefin sulfonates, monoglyceride sulfates, higher fatty alcohol-lower alkoxysulfates, and linearly higher alkylbenzenesulfonates. Most preferred higher alkyl sulfates include those having 12 to 16 carbon atoms, and most preferred higher alkyl-lower alkoxysulfates include those having 16 to 18 carbon atoms, the higher alkyl being represented by a lauryl group, which additionally contain 2 or 3 ethoxy groups per mole . The most preferred higher fatty alcohol sulfate is lauryl sulfate, and particularly preferred the higher fatty alcohol-lower alkoxysulfate is sulfated di- or triethoxylated lauryl alcohol. Most preferably, the anionic detergent is a mixture of a higher alkyl sulfate and a higher alkyl ether sulfate, whereby any component may be present in a greater amount, and the ratio of these components will usually be in the range of 10: 1 to 1: 10 or 7: 1 to 1: 7. for example in the range of 1: 5 to 5: 1. These anionic detergents can be used in the form of their water-soluble salts, usually alkali metal salts (e.g. sodium, potassium), ammonium salts, amines (such as dimethylamine and trimethylamine) or lower alkanolamines (such as triethanolamine, diethanolamine and monoethanolamine). Examples of useful detergents include Ammonium lauryl sulfate, sodium lauryldietoxysulfát, amóniumlauryltrietoxysulfát, alpha olefin sulfonate, sodium C _16, C ₁₄ paraffin sulfonate

However, for best results, it is preferable to use a higher alkyl sulfate or a mixture of higher alkyl sulfate and higher alkyl ether sulfate, which may be, for example, lauryl sulfate and lauryldiethoxy or triethoxysulfate, the higher alkyl sulfate being present in greater proportion and the ammonium or triethanolamine anionic detergent salt. also present in greater proportion.

The water used in the aqueous compositions of the invention, which may include preferred shampoos, is preferably deionized water with a hardness of less than 10 ppm, expressed as calcium carbonate, but other water may be used if circumstances so require. In order to ensure that the composition of the invention does not contain any microorganisms, it is preferred to use irradiated deionized water and keep the mixing vessels, storage tanks, tubes and containers used in complete cleanliness.

The proportions of the individual components of the composition according to the invention are selected so as to achieve the desired significant increase in the conditioning effects of the fiber treatment. This enhancement of the conditioning effect of the fiber conditioning composition of the present invention is achieved when the cationic surfactant conditioning agent is present in an amount for conditioning the textile material, normally solid water-insoluble polyethylene is present in the composition in an amount sufficient to enhance the conditioning effect a cationic agent in the treatment of a textile material wherein the polyethylene is dispersed in water, and the hydrocarbon or mixture of hydrocarbons in the liquid state is present or present in an amount that helps liquefy normally solid polyethylene and render it water dispersible in the presence of said amount of quaternary ammonium salt and water.

It has already been said above that the fiber and hair conditioning compositions of the invention may be in various physical forms, but the liquid form is preferred, and in a preferred embodiment the form is a hair shampoo. Such compositions should be chemically and physically stable for storage, should not deteriorate to an unacceptable quality upon storage (in particular, they should not lose their improved conditioning properties) and should not settle or separate or unpleasant changes in viscosity. In the shampoos according to the invention, it is desirable that their viscosity be in the range from 1 to 15 Pa.s (i.e. 1,000 to 15,000 centipois) at room temperature (25 ° C), preferably in the range from 3 to 6 Pa. ss (3000-6000 cp) and more preferably should have a viscosity of about 3.5 or 4 Pa.s (3500 or 4000 centipois) at this temperature. These shampoo compositions do not settle upon storage and essentially retain their improved hair conditioning conditioning properties. Also, the viscosity does not change over time, so that it remains the same as at the time of manufacture, sometimes with an expected increase in the short time after the shampoo preparation is completed, so that the desired utility viscosity approximately corresponds to the viscosity of the product.

The improved hair treatment is visibly evident for any potential user of these conditioning compositions or v691 / 94H shampoos compared to control compositions that have not been used with either polyethylene or mineral oil, and this improvement is measurable even when using standard tests to evaluate ease of wet combing, ease of dry combing, and static charge retention (in terms of unpleasant flying). A prospective shampoo user will notice that, after shampooing with the composition of the invention, the hair is easier to comb, both wet and dry, easier to shape, and less subject to static energy accumulation and unpleasant flying. Experimental tests have also shown that the force required to move the comb through the standard hair strand after treatment of the hair with the conditioning composition of the invention or after shampooing these hair with a shampoo based on the composition of the invention (and rinsing) is less than that required with the control compositions. shampoos for similar purposes. Also, the flying behavior of the hair is less than when using control products intended for shampooing strands. These results were confirmed by tests conducted by several experienced evaluators, using both experimental and control products in comparative tests to assess combing ease, static and formability characteristics.

It is not desirable that the use of the compositions of the invention, which include shampoos, is different from the conventional use of hair care compositions and shampoos. These conditioning (or conditioning) agents may be applied at room temperature or at elevated temperature in normal amounts and may be left on the hair for varying periods of time, depending on the extent of the desired treatment. Usually the temperature of the conditioning agent and hair is in the range of 15 to 50 ° C, preferably 20 to 40 ° C, wherein the conditioning composition is in contact with the hair for 30 seconds to ten minutes, preferably in the range of one to five minutes. The amount of composition applied is usually in the range of 0.1 to 25 grams, often 0.2 to 10 grams, and more often 0.5 to 2 grams, depending on the non-aqueous and non-solvent components of the compositions. In the case of shampoos, the amount thus applied ranges from 0.5 to 50 grams, often from 2 to 15 or 20 grams, and more often from five to ten grams, often from 2 to 15 or 20 grams, and more often from five to ten grams per unit. the use.

v691 / 94H

The applied composition may be uniformly brushed into the hair and / or comb and then rinsed, leaving the composition on the hair and / or partially removed, for example, with a towel. If a shampoo is used to wash and condition the hair, the shampoo is first left on the hair in the form of water foam for a sufficiently long time, usually 1 to 5 minutes, which is sufficient time to treat the hair and then rinsed with water. The hair can then be combed wet, dried, for example, by blow drying and using a brush or comb to achieve the desired hairstyle.

No special precautions are needed to prepare the compositions of the invention, which include shampoos, but it is desirable to increase the stability of the shampoo and aqueous product compositions both in storage and in use. to form an aqueous dispersion of water-soluble lipophilic sulfates and / or sulfonates and additives, separately dissolve and / or disperse a cationic conditioning agent, such as a quaternary ammonium halide and normally solid polyethylene in liquid mineral oil at elevated temperature (70-90 ° C) and then mix the two solutions and / or dispersions to form a stable dispersion. If the ingredients present are those which are water-soluble and / or dispersible, these ingredients may be mixed into the aqueous phase. For additives which are neither soluble nor dispersible in an aqueous medium, such as paraffin, isoparaffin and microcrystalline wax, they may be mixed with the above mentioned three lipophilic materials, or in some cases they may be added to the mixture of aqueous and lipophilic materials either The perfumes are usually added to the other mixed ingredients after cooling to room temperature, the reason being to avoid their loss due to evaporation or heat decomposition. If the described procedure is not followed and the ingredients are not mixed separately, the result is unstable products which undergo storage separation or phase loss during storage, and such unstable products tend to deteriorate hair and shampoo conditioning compositions which were prepared by the process of the invention.

The conditioning compositions of composition A above were prepared by co-heating the water-soluble and water-dispersible components of the composition with all or almost all of the water referred to in the composition (if less than the total amount of water is used at this stage) the residue was added to the mixture of the heated aqueous portion and the heated lipophilic melt or dispersion), the polyethylene, mineral oil, paraffin wax and some other "liquid" hydrocarbons were heated together to about 80 ° C, followed by mixing the two premixes (heated) and this stirring was continued for 10 minutes with stirring. In this way, a stable shampoo was prepared which did not settle or eliminate the storage phase for one month at elevated temperature, which corresponds to storage for at least one year at room temperature. The prepared shampoos were tested for conditioning by a group of at least five experienced evaluators of these products, which tested hair strands and / or scalp that were shampooed with this composition, rinsed with water and dried, and evaluated different conditioning conditions characteristics such as ease of wet combing, ease of dry combing, static charge retention, volatility and formability.

In a similar manner, a control shampoo B having the same composition as shampoo A was prepared but did not contain polyethylene and mineral oil, which were replaced with water. Both compositions had a pH of about 6.5 and a viscosity at 25 ° C of about 3.5 Pa.s or 4.0 Pa.s (i.e. 3500 or 4000 centipois). Hair strands shampooed with this control composition, subsequently rinsed and dried, in the same manner as composition A, were also evaluated by members of the review group, and these scores were compared to the hair shampooed with composition A subsequently rinsed and dried. The review group concluded that all of the modifying effects of using the A composition were significantly better than those obtained with the B composition. In a numerical evaluation at a scale of 1 to 5, the higher the number the better the conditioning effect, the results after treatment with composition B were about 2 and for treatment with composition A ranged around 5.

The shampoo of the above composition was prepared in the same manner as described for the preparation of the shampoo of Example 1, wherein the melt of the lipophilic materials contained polyethylene, mineral oil, paraffin wax and isoparaffin. The resulting shampoo had a pH of about 6.5 and a viscosity of about 3.5 or 4.0 Pa.s (or 3500 or 4000 centipois) at 25 ° C and was storage stable while retaining its original improved conditioning properties during hair conditioning and there was no phase loss or separation or other deterioration in storage for up to one year.

When testing the properties of this shampoo compared to a control shampoo having the same composition but not containing polyethylene, this shampoo had measurably better conditioning properties in hair styling, the v691 / 94H rating of which is in summary of wet combing ease, dry combing ease, less statics and of less hairiness in the hair strands treated with the composition of the invention as compared to the strands shampooed with the control composition.

In the above composition, anionic detergents have been interchanged, the proportions of the individual components are modified in the composition, and hair adjuvants are added to this composition, confirming that the presence of mineral oil solubilized polyethylene enhances the conditioning characteristics of the shampoo. hair styling. The products of the present invention illustrated in Examples 1 and 2 significantly outperform other prior art conditioning shampoos of this type, the reason for this improvement being the presence of polyolefin as a hair conditioning conditioning agent. in conjunction with a mineral oil and a cationic conditioning surfactant. The differences in presentation are evident not only in instrumental testing or by an experienced evaluator, but are also clearly visible to the average consumer, the user of these products. Shampoo hair can be combed more easily in a wet state and brushed or combed dry. Conditioned (conditioned) hair is easier to fix and yield, which is at least in part due to the low static charge that is generated on them, which causes the individual hair not to repel each other, and these repulsive effects cause the aforementioned unpleasant flying .

The compositions described in Examples 1 and 2 are hair conditioning shampoos, but the composition of the present invention can also be used to formulate fiber conditioning and non-shampoo conditioners. Thus, these compositions can be applied to other natural fibers, such as cotton, flax and wool, and synthetic fibers, such as nylon, polyester, acrylic, and acetate, to treat them. Also, when the compositions of Examples 1 and 2, which contain the desired cationic conditioner, polyethylene and mineral oils, are used as the691 / 94H solutions in an alcoholic or other suitable solvent or are converted to a gel or other suitable form and are applied to the hair in the form of a spray, or as a brush to be brushed, or as a gel to be rubbed into the hair, even with the compositions thus applied, the hair is clearly conditioned. If these applications are carried out using aqueous systems, then even in these cases a better finish will be achieved than in cases where no mineral oil and some other solubilizing hydrocarbons are used in these compositions (in this case the shampoo cannot be prepared in the usual state, because polyethylene will not sufficiently dispersed or emulsified).

Example 3

If, in the composition variations of the compositions of Examples 1 and 2, the various ingredients are omitted in such a way that the prepared shampoos contain only the essential ingredients, which is an anionic surfactant, a cationic surfactant, polyethylene, a solubilizing liquid hydrocarbon (mineral oil) and water, shampoos are less viscous for shampooing and hair conditioning. In the case where the mineral oil is omitted from the composition of these compositions, the polyethylene cannot be dispersed or emulsified in the system. If other lighter or heavier mineral oils and other normal liquid hydrocarbons are used in place of the described mineral oil to solubilize polyethylene, then the conditioning properties are improved over similar compositions not containing these solubilizing agents, but sometimes these other hydrocarbons are cosmetically unacceptable or toxic. Mineral oil is considered to be harmless, helps to give shampoo hair shine and often acts as a better solubilizing agent for polyethylene, and due to all these functions it is considered to be a highly preferred solubilizing agent in the compositions of the invention.

If the compositions of the invention are modified in such a way that some of the desired ingredients of the conditioning and shampoo compositions of the invention, as described in the above-described examples, are replaced by the other ingredients listed in the description, the desired conditioning effects will also be achieved and cleaning effects in hair treatment, these effects being higher when a combination of polyethylene and mineral oil is present. These include, for example, replacement of anionic detergents or anionic detergent with triethanolamine lauryl sulphate, sodium myristyl sulphate, potassium cetyl sulphate, triethanolamine myristyldiethoxysulphate, sodium paraffin sulphonate (paraffin containing 14 carbon atoms), or olefin 10 sulphonate (olefin 10 sulphonate). The polyethylene may be replaced by higher or lower molecular weight polyethylenes (within the stated molecular weight range of 1000 to 10,000), which may be AC polyethylenes 6A, 7A, 8A and 725 (Allied Signal) and products E-12, -14 and -43 (Eastman Chemical Corporation) having a molecular weight of 1800, 2300, and 4500. Instead of said mineral oil, mineral oils having a molecular weight of about 550 or greater and less can be used, with an upper molecular weight limit of up to 1000 and a lower 150. Or. it is possible to replace at least in part the cationic surfactant, namely distearyldimethylammonium chloride, trilaurylmethylammonium chloride, stearylcetyldimethylammonium chloride or dilauryldiethylammonium chloride. Also in these compositions, any of the additives described above, or some of them, may be omitted.
