Description

A fiber conditioning composition imparting a pearlescent appearance and use

Technical field

The present invention relates to a fiber conditioning composition imparting a pearlescent appearance and to the use of this composition for shampooing and conditioning hair. At the same time, hair washing with these shampoos results in a hair treatment, after which the hair is pliable, i.e. easy to comb, having a relatively low electrostatic charge, and the conditioning effect thus obtained is more intense than with conventional shampoos known so far.

BACKGROUND OF THE INVENTION

Hair conditioning shampoos are well known in cosmetics and are described in many patents and patent applications. Cationic surfactants, such as quaternary ammonium salts, have been suggested as hair dressing agents. These substances have been designed for the same purpose in hair shampoos. Similarly, various silicones and other water-insoluble conditioning agents have been proposed, including waxes, fats and oils. These shampoos have heretofore been produced in solid, gel, cream and liquid form, and liquid shampoo forms include solutions, emulsions, suspensions or dispersions. When shampoos are in the form of an emulsion or suspension (or dispersion), the ingredients sometimes separate during storage, which may be detrimental to their commercial success.

The present invention also encompasses the use of a fiber conditioning composition to impart a pearlescent appearance to shampooing and conditioning human hair.

The process for treating a fibrous material is characterized in that an amount adjusting fiber of the composition of the invention is applied to the fibrous material (specifically the hair), then the fibrous material composition is rinsed leaving the conditioning agent on the fibrous material.

The hair shampooing and conditioning process is characterized by comprising applying a shampoo and conditioning portion of the hair conditioning shampoo of the present invention to human hair or to the head and rinsing the shampoos out of the hair while leaving a conditioning amount on the hair.

As mentioned above, the shampooing and conditioning composition of the present invention may be in liquid cream, gel or paste form, only needing to include a water-insoluble conditioning agent and a saturated long-chain primary alcohol in an aqueous environment. Also present is a cationic fiber treatment agent (which also acts as a surfactant, but will only be considered as a conditioning agent here). In some cases, stabilization efficiently performed with long-chain saturated primary alcohols (for the sake of simplicity the term "or derivatives" will be omitted below) may not necessarily be present, but other advantages of these compounds such as the pearlescent effect and improving the conditioning process speaks for these compounds. Water-soluble organic synthetic detergents, preferably anionic detergents, more preferably higher alkyl sulfates and / or higher alkyl ethoxy sulfates are also present in the hair shampoo. Such compositions may exist in various non-liquid forms, but are preferably in the form of an emulsion or suspension (or dispersion) in an aqueous medium and are preferably liquid.

The water-insoluble conditioning agent fibers are those agents, among which may be advantageous to include: an organosilicon compound, such as non-volatile silicones (especially aminosilicones), between which include dimethicone, polyethylene, paraffins, petrolatum, microcrystalline waxes, C ₈ _ ₃₆ (mixed) fatty acids and their corresponding triglycerides, stearyl stearate, and quaternary ammonium salts and amines (which are classified herein as conditioning agents rather than surfactants, although acting as both). In this case, organosilicone compounds and silicones may be used as conditioning agents for fibrous materials, many of which have been described in previously modified patents and published applications, but it has been found that aminosilicones are usually present in the compositions of the present invention. more effective conditioning agents than conventional silicones, with the aminosilicones of this type being even better, with aminosilicones of formula I being most preferred for use.

Since the molecular weights of high polymers sometimes vary depending on the measurement technique used, it has been suggested to give a basic reference to the measurement technique given case for identifying aminosilicones rather than relying on a given molecular weight. Preferably, the disclosed amino silicones are provided by Dow Coming Corporation and are referred to as Dow Coming Aminosilicone A in the Examples.

Polyalkylenes which can be used as water-insoluble conditioning agents in said compositions are preferably those having a molecular weight ranging from 1000 to 5000, more preferably from 1000 to 4000, and even more preferably from 2000 to 2500, for example about 2000 Oxidized versions of these polyalkylene polymers can also be used to form larger carboxyl-terminated hydrocarbons. Although ethylene will usually be used as the alkylene moiety of these polymers, hydrocarbon polymers may also be used in accordance with the invention, each having 1 to 5 carbon atoms, preferably 2 to 3 carbon atoms, and having a molecular weight ranging from 1000 to 10 000 or is under certain conditions even higher, typically the polymer selected will be ethylene and / or 35 propylene, most often ethylene (polyethylene) being used.

The cationic conditioning agents, which may also be considered as secondary conditioning agents in the shampooing and conditioning compositions of the invention, are preferably 50 quaternary ammonium salts; however, other cationic compounds which have the ability to modify the fibers may be used, at least in part. For example, the commonly known amines, amine salts, imidazoline salts and betaines, as well as the cationic agents described in U.S. Patent No. 4,000,077, which may replace, at least in part, the quaternary ammonium salt, include: they may be these substances

-66586571 B6 combined with other cationic and anionic surfactants as disclosed in U.S. Patent Nos. 4,896,422 and 4,888,119.

Examples of preferred quaternary ammonium salts include:

RN ⁺ X 'in which:

generally R is alkyl, wherein at least one of the R groups is lower alkyl and at least one is higher alkyl and the other R groups are higher and / or lower alkyl groups, wherein R is R ⁹ , R ¹⁰ , R ¹¹ , R ¹² . Preferably R ^{9 is a} lower alkyl group having 1 to 4 carbon atoms, while R ¹⁰ and R ¹¹ are a higher alkyl group having 10 to 40 carbon atoms, R ¹² is a higher or lower alkyl group and X 'is an anion forming salt, such as a halide, lower alkyl sulfate or lower carboxylic acid residue, for example chloride, bromide, methyl sulfate, ethyl sulfate, citrate or acetate. The lower alkyl group preferably contains 1 to 3 carbon atoms, more preferably 1 to 2 carbon atoms, and most preferably in most cases a methyl group will be used, while the higher alkyl group will preferably be an alkyl group containing 10 to 22 carbon atoms, more preferably 12 to 18 or 20 carbon atoms and most preferably 14 to 18 carbon atoms, for example 16 or 18 carbon atoms. The anion is preferably a halogen such as chlorine, bromine or iodine, preferably chlorine and bromine and most preferably chlorine.

The number of lower alkyl groups bound to the quaternary nitrogen will preferably be 1 or 2, and the number of higher alkyl groups will preferably be 2 or 3. Such compounds therefore have 2 or 3 long chain alkyl groups containing 12 to 20 carbon atoms and 1 or 2 alkyl groups. short chain groups containing 1 or 2 carbon atoms. It has been found that it is desirable that the quaternary ammonium salt contain at least 30 carbon atoms and preferably at least 34 carbon atoms. The most preferred higher alkyl group is cetyl and stearyl and the most preferred lower alkyl group is methyl. More preferred quaternary ammonium halides include tricetylmethylammonium chloride and distearyldimethylammonium chloride, but other quaternary ammonium salts such as dicetyldimethylammonium chloride and tristearylmethylammonium chloride and their corresponding bromides, amines, amine salts, betaines and US patents are also used.

These cationic surfactants and complexes may be used at least as part of the cationic surfactant contained in the composition of the invention.

The long-chain primary alcohols included in the compositions of the present invention are usually preferably saturated hydroxyl-terminated compounds. The distribution of such alcohols is equal to the distribution of homologous alcohols having the same number of carbon atoms, usually having an average of 24 to 45 carbon atoms (depending on weight, preferably having 28 to 42 carbon atoms, more preferably having about 30 to 40 carbon atoms and most preferably having 30 to 40 carbon atoms). If the average number of carbon atoms in the chain is less than 24, then the desired efficiency of such alcohols in the formulations of the invention decreases, i.e. the stabilization of the fiber treatment deteriorates and the pearlescent effect decreases, while if the chain length is greater than These alcohols are then unable to disperse satisfactorily in the compositions described.In addition, the long chain alcohols may be replaced at least in part by similar compounds, such as the corresponding alkoxylated alcohols. Of these "derivatives", alkoxylated alcohols are preferred, with ethoxylated alcohols being most preferred, which will usually contain up to 20 ethoxy groups per mole, for example 10 to 20, with alcohols being preferred. used according to the invention will usually be used alone or in a mixture with relatives

-7EN 286571 B6 compounds from the group of 'derivatives', those where the alcohol constitutes the majority of the total 'alcohol and derivative' content. Petrolite Corporation manufactures and sells through the Petrolite Specialty Polymers Group substances that can be used in the compositions of the invention, these products being available under the trade name Unilin ™ -alcohols as also described in the corresponding technical bulletin. Such alcohols may be from 75 to 90%, for example from 80% to 85%, conventional commercial products, with the remainder consisting essentially of all saturated hydrocarbons of the corresponding chain length. In the case of these products, the distribution curve of the alcohols present is substantially bell-shaped, with no chain length of alcohol more than 10% in total, and the corresponding hydrocarbon having a substantially flat distribution curve, each hydrocarbon being 1 or 2%. These distribution curves are presented as bar graphs in the aforementioned Petrolite Bulletin. Said alcohols and the corresponding hydrocarbons typically comprise at least 80% of alcohols (and the corresponding hydrocarbons) having a chain length of from 18 to 20 to 54 carbon atoms; an alcohol having an average of about 30 carbon atoms is at least 80% constituted by an alcohol having a chain length in the range of 18 to 20 to 44 carbon atoms, and if the alcohol has an average of about 40 carbon atoms it is at least 80% by chain lengths in the range from about 28 or 30 to 54 carbon atoms. Examples of primary long-chain alcohols are Unilin-425 having an average of 30 carbon atoms in its chain, Unilin-550 having an average of 40 carbon atoms with Unilin-350 having an average of about 26 carbon atoms in its chain. The Unithox-550 derivative is an ethoxylated alcohol having an average of 40 carbon atoms in the alkyl chain and is ethoxylated with up to 20 ethoxy groups, preferably 13 ethoxy groups.

The water-soluble synthetic organic anionic detergent is typically represented by a lipophilic sulfate or sulfonate; however, other hydrophilic groups such as phosphate and phosphonate may be used. The salt-forming cation of such compounds is typically represented by an alkali metal, ammonium group or alkanolamine, with sodium and ammonium salts being preferably used. For an anionic detergent, it is further preferred to use a lipophilic sulfate or a mixture of sulfates. As the lipophilic portion of the anionic detergent, an alkyl group, preferably a higher C 12 -C 18 higher alkyl group is used, although a wider alkyl group of 10, 8 and 6 or up to 18 or 20 carbon atoms may also be used. According to the invention, such detergents have been found to be most compatible with the described shampoos and provide good cleaning and conditioning properties while not disturbing the pearlescent and conditioning effect of the composition. Particularly desirable detergents are ammonium lauryl sulfate and sodium lauryl ethoxy ether having 1 to 6 ethoxy groups per mole, preferably 2 or 3 ethoxy groups per mole.

These preferred anionic detergents as described above may be at least partially replaced by other detergents of this type as described in McCutcheon ' s Detergent and Emulsifiers, North American Edition, published in 1984. Furthermore, amphoteric and ampholytic and zwitterionic detergents and relatively less nonionic detergents. Such detergents are also disclosed in publications commonly known in the art.

In some cases, a relatively small amount of such surfactants may also be used, and the term is used herein in a broader sense and includes various emulsifiers and dispersants (for use in non-hair shampoo conditioners and fiber conditioning compositions). .

For these preferred detergent combinations mentioned above, they are a combination of a higher fatty alkyl sulfate and a higher fatty alkyl ethoxylate sulfate, with preferred ratios being 2: 1 to 8: 1 (alkyl sulfate: alkyl ethoxy sulfate), when the alkyl sulfate is an ammonium salt and the alkyl alkoxy sulfate is a sodium salt. Each such detergent may be used alone and in some preferred formulations the ethoxylated detergent is omitted.

The various desired components of these compositions are dissolved and / or form an emulsion and / or suspension in an aqueous medium. Such an environment may contain various ingredients which do not adversely affect the composition and effects of the shampooing and conditioning compositions of the present invention, which are well known in the art, but it is useful to mention them in more detail as these are particularly desirable components of the composition and contribute significantly to the desired properties. Higher fatty alkanolamides have long been known as blowing agents and foam stabilizers. Such compounds contain the usual 12 to 16 carbon atoms in the acyl group that has reacted with a lower (1 and 3 carbon atoms) mono- or di-alkanolamine. The best alkanolamide in said formulations is considered to be lauric monoethanolamide or coconutethanolamide, which has an approximately equivalent effect, and other blowing agents and foam stabilizers may be used either wholly or in part. These may be betaines and related materials. Various resins and other thickening materials are also useful for shampoo compositions, but it has been found that hydroxylcelluloses are most preferred for the compositions of the present invention. These celluloses are available from Aqualon Corporation under the tradename Natrosol; Natrosol 250 HHR and Natrosol 330 CS are preferably used in the composition of the invention, the content of the first being 2 to 5 times greater than the content of the second. Although hydroxyethylcellulose is preferably used, it can be at least partially replaced by, for example, a synthetic resin and thickeners such as methylcellulose, hydroxypropylmethylcellulose, Polyquatemum ™ -10, modified starches and natural resins and thickeners such as guar resin, depending on the desired product . Another important component of the composition is mineral oil, wherein polyethylene is used as a hair conditioning agent. Here, the mineral oil acts as a substance which solubilizes polyethylene and aids in its dispersion, should the dispersion in the composition be insufficient; then there would be phase elimination and the conditioning effect on the hair would be small.

Other ingredients that may be used in the compositions include: ethylene glycol monostearate, ethylene glycol distearate and propylene glycol distearate, all of which have pearlescent properties, viscosity regulators such as propylene glycol and sodium chloride, pH adjusting agents such as citric acid and citrate; sequestering agents such as EDTA, antifreeze agents such as propylene glycol, solvents ethanol and isopropanol, preservatives and antioxidants such as Germaben II (Sutton Laboratories), zinc pyrithione or Climbazole ™ (see US 4,867,971) and finally dyes and perfumes.

The water used to prepare the aqueous medium may be present not only in liquid formulations, but also in gels, pastes and creams. Deionized and irradiated water of substantially zero hardness is preferably used for this purpose, but tap water may also be used, and it is preferred that the water hardness is kept below 50 ppm (this hardness is expressed as calcium carbonate). In some cases, water with a hardness of 200 ppm can also be used, but usually this should be avoided.

In order to achieve the desired properties described, it is necessary to maintain certain proportions of the components present in the liquid conditioning and shampoo compositions, and these ratios will now be indicated.

The surfactant content for both conditioning compositions, for example hair dressings and shampoos, will range from 1 to 35% by weight, preferably from 2 to 35% by weight, and most preferably from 3, 5 or 8% to 25% by weight, a lower range applies to conditioning compositions and a higher range to shampoos. That is, the surfactants are generally present in the shampoos in an amount of 5 to 35% by weight, preferably 8 to 25 or 30% by weight, and most preferably 10 to 20% by weight. In the case of alkyl or alkyl ethoxylate sulfate in shampoos, the proportion is usually in the range of 5 to 25% by weight, preferably in the range of 10 to 20% by weight, and most preferably in the range of 10 to 15% by weight of the first and up to 15% by weight.

Preferably 0 or 1 to 10% by weight and more preferably 0 or 1 to 5% by weight of the latter. If each such sulfate detergent is used alone, then the percentages for alkyl sulfate apply.

The water-insoluble conditioning agent (a) (no cationic surfactants included) are represented in such a ratio that alone or in conjunction with cationic surfactants ensures that the fiber or hair treatment is sufficient. That is, they are present in an amount of 0.3 to 10% by weight in both compositions, both in the conditioning composition and in the shampoo composition. Preferably, their content is from 0.3 to 7% by weight and most preferably from 0.3 to 5% by weight. The content of the cationic surfactant for both fiber conditioning compositions and shampoos is usually from 0.1 to 5% by weight, preferably from 0.1 to 3% by weight, most preferably from 0.1 to 0.3 to 0.7, or 1% by weight. Saturated long chain primary alcohols or derivatives thereof are present in an amount of 0.5 to 10% by weight, preferably 0.5 to 5 or 6% by weight, and more preferably 1 to 5% by weight.

Such compositions may also contain 0.2 to 2% by weight of hydroxyethylcellulose (or other suitable reinforcing agents), 2 to 5% by weight of lauric monoethanolamide or diethanolamides 0 or 0.5 to 2% by weight of microcrystalline wax and 0 or 0.5 to 1% by weight. petroleum jelly by weight.

For other compositions of a similar type, the first six ranges will be the same as those just mentioned, but will also contain 0.3 to 2% by weight polyethylene and 0.3 to 2% by weight mineral oil, preferably 0.5 to 1.5% by weight, respectively. 0.5 to 2% by weight. Furthermore, hydroxyethylcellulose and lauric monoethanolamide are present in the same proportions as mentioned in the preceding formulations, in contrast to paraffin wax and isoparaffin, whose ranges are 0.1 to 2% by weight, preferably 0.1 to 1% by weight, respectively. 0.1 to 2% by weight, preferably 0.1 to 0.5% by weight.

According to a further embodiment of the invention, the shampoo comprises polyethylene as a conditioning agent together with a quaternary ammonium halide and a high molecular weight lipid solubilizing agent (e.g. mineral oil) to solubilize the polyethylene, wherein the component ratios are the same as the previously mentioned anionic ratios.

Detergents, a cationic conditioner, a saturated long-chain primary alcohol and / or derivatives thereof, water and additives present, wherein in such a composition the amino silicones may be omitted and the amount of alkoxylate detergent may be increased to 15% by weight, while the amount of polyethylene and the mineral oil will generally be 0.3 to 2% by weight of each and preferably will be between 0.5 and 1.5% by weight and 0.5 to 2% by weight, respectively. The composition also contains other desirable components, including hydroxyethylcellulose, in the range of 0.2 to 2% by weight, 2 to 5% by weight of lauric monoethanolamide, 0.1 to 1% by weight paraffin wax and finally 0.1 to 2% by weight. up to 0.5% by weight of isoparaffin.

In another shampoo of the invention, the amounts of anionic detergents, cationic surfactants, aminosilicones, long-chain saturated primary alcohols and / or derivatives thereof, other ingredients and water are the same as the first of these types of formulations that have been reported, except that wherein the long-chain saturated primary alcohol (which may include derivatives thereof) preferably contains 0.5 or 1 to 2 or 3% by weight of chains with an average length of about 30 carbon atoms and up to 2 or 3% by weight of chains with an average length of about 40 atoms carbon. 0.5 to 2% by weight of long chain polyethoxylated saturated primary alcohol (derivative) is also present in a modified version of the formulation, the alcohol having an average of about 40 carbon atoms and being ethoxylated with 10 to 20 moles, for example 13 moles, of ethylene oxide per mole. Both of these formulations which do not contain resin or resin-like material (hydroxyethylcellulose) may be supplemented with 2 to 5% by weight of lauric monoethanolamide, 0.5 to 2% by weight of C18-36 triglyceride and 0.1 to 0.5% by weight of citrate, preferably sodium citrate. A further modification of this formulation comprises 0.1 to 1% w / w paraffin wax and 0.5 to 1.5% w / w solid polyethylene having a molecular weight ranging from 1000 to 4000 and with 0.5 to 2% w / w mineral oils having a molecular weight of from 300 to 800, which here functions as a solvent for polyethylene.

Other preferred formulation types contain the same amounts of anionic detergents, cationic surfactants, aminosilicones, long-chain saturated primary alcohol, water and shampoo ingredients as the preceding formulation, but additionally contain 0.25-5% by weight of Cis-36 triglyceride as a conditioning agent. (mixed) acids. Such compositions may additionally contain 2 to 5% by weight of lauric monoethanolamide, 0.2 to 2% by weight of hydroxyethyl cellulose, 0.5 to 2% by weight of microcrystalline wax and 0.5 to 1% by weight of petroleum jelly. Instead of microcrystalline wax and petrolatum, 0.5-1.5% by weight of the polyethylene described above and 0.5-2% by weight of the mineral oil described above can be used.

For the gels, pastes and thickeners of the present invention, it is desirable that the amount of optional and adjuvant components be in the same ranges as in the aqueous compositions, the amount of water usually being reduced to about 30 to 40% by weight. In some cases, water may be replaced by up to 50% other solvents, for example ethanol or isopropanol, but this is usually not more than 20%.

Although the shampooing and conditioning compositions of the present invention may be in the various physical forms mentioned above, a liquid form is preferred, and most preferably, the form is a liquid shampoo to condition the hair simultaneously. In order to be acceptable for commercial purposes, these compositions must be chemically and physically stable. Their effects should not deteriorate below acceptable levels by storage and should not contain components that are falling out or that are eliminated during storage. The long chain primary alcohols present (Unilin or Unithox type) present stabilize the composition according to the invention and, in addition, give the composition an active pearlescent appearance and increase the conditioning effect. These shampoos also have the desired viscosity, i.e., viscosity such that they flow easily but are not so thin that they flow in an uncontrolled manner. Required

The viscosity ranges from 1,000 Pa.s to 15,000 Pa.s (1000 to 15,000 centipoise) at room temperature (25 ° C), suitably from 3,000 Pa.s to 6,000 Pa.s (3000 to 6000). centipoise). The shampoos according to the invention are not deposited or separated and their storage is not destroyed or deteriorated as demonstrated by accelerated aging tests at elevated temperature. The viscosity of the shampoo may vary slightly upon storage, but these changes do not significantly affect the properties of the shampoo. The desired viscosity used can be achieved by preparing a shampoo of a certain viscosity that allows for some expected viscosity change before use.

The enhancement of the conditioning effect achieved by the use of the compositions of the present invention, as compared to when the said conditioning agents have not been used, is already apparent to the casual consumer of the shampoo or conditioning composition of the present invention, this improvement being measurable by standard tests used to evaluate treatment and the effect of their components, which include wet combing easing, dry combing easing, hair-holding ability, static charge suppression, and flying ability. An accidental shampoo user must state that after use of the shampoo of the present invention, hair is easier to comb, both in wet and dry condition, compared to hair treated with a shampoo other than the shampoo of the invention (in which conditioners have been omitted) components or some of them). Scientific tests have also shown that the force required to move the comb combing the hair that has been treated (shampooed) with the shampoo of the invention and rinsed is measurably less than the force required to move the comb that has been treated with the comparator. These results were confirmed by panel tests, where the experimental and comparative products were evaluated in blind tests, assessing ease of combing, ability to maintain hairstyle and static characteristics and effects.

It is not desirable that the use of the compositions of the invention, including shampoos, be different from the use of commonly used hair conditioning shampoos and other fiber conditioning compositions. The conditioning compositions may be applied at room temperature or at any elevated temperature in normal amounts, and may be left on the hair for various periods of time depending on the desired range of treatments. Usually, the conditioning agent is allowed to act on the hair at a temperature in the range of from 15 ° C to 50 ° C, preferably from 20 to 40 ° C, and the treatment time ranges from 30 seconds to 10 minutes, preferably from one to five minutes. The application rate of the composition is in the range of 0.1 to 25 grams, often 0.2 to 10 grams or 0.5 to 2 or 5 grams, depending on the weight of the non-aqueous and non-solvent components of the composition used. The amount of shampoo used ranges from 0.5 to 50 grams, often from 2 to 15 or 20 grams, and most often from 5 to 10 grams per disposable. The applied conditioning composition can be combed into all hair by a comb or brush and then washed; it is also possible to leave the composition on the hair or to partially remove it from the hair with a towel. The shampoo that is used to wash and condition the hair is allowed to act on the hair as a water foam for a period of time, usually 1 to 5 minutes, a time sufficient to condition the hair; then the composition is removed from the hair with water, and then wet hair can be combed, dried, blow-dried and combed or brushed dry to the desired hairstyle.

The preparation of said compositions, including shampoos, need not be complicated, but in order to achieve the best stability and pearlescent effect and best conditioning effect for the storage of the compositions of the invention, it is desirable to disperse the water-soluble lipophilic kraft and / or sulfonate detergent (s). water at elevated temperature, i.e. at 70 to 95 ° C, to further prepare the molten or liquid mixture by dissolving a dispersion of a cationic conditioning agent which is a quaternary ammonium salt (may be omitted) in any lipophilic substance such as a hydrocarbon such as polyethylene mineral oil, microcrystalline wax, technical petrolatum, paraffin and isoparaffin, a long-chain alcohol, triglyceride and stearyl stearate at elevated temperature, and mixing the two mixtures at said elevated temperature; and then the heated aminosilicone may be mixed into the mixture (which may sometimes also include a lipophilic substance), the mixing of the individual portions and the mixing of the portions being carried out at approximately the same

-12GB 286571 B6 temperature. Sometimes it is desirable that the aminosilicones be admixed only after preparation of the master premix, which increases the stability of the product. If the present ingredients are water-soluble and / or solubilizable, they may be mixed into the aqueous phase of the material; however, if they are neither soluble nor solubilizable in water, they may be mixed into lipophilic substances, for example hydrocarbons, or may in some cases be added to a mixture of hydrophilic and lipophilic materials either before or after cooling to room temperature. Perfumes are usually added to the mixture after cooling to room temperature and the aminosilicones before cooling. The reason for adding the perfumes to the cooled mixture is to avoid their loss due to evaporation of their components and to prevent degradation caused by their heating. If the preparation of the compositions does not follow the described procedure and the individual components of the composition are mixed randomly, unstable products that may decay or phase out upon storage may result and these unstable compositions tend to have worse conditioning properties than stable conditioning compositions and shampoos, which have been prepared according to the invention.

The compositions of Example 1 are prepared as described herein by first preparing a mixture of hydrophilic components and a mixture of lipophilic components separately and then mixing the mixtures, all of which are carried out at an elevated temperature, for example at 80 ° C. Next, 5 is followed by mixing the aminosilicones, if present, and sodium chloride, which functions as a viscosity regulator, and finally adding perfumes to the non-perfumed shampoo that has been cooled to 25 ° C:

The products thus prepared are then actively pearlescent liquid shampoos having a viscosity of 10 ranging from 3,000 Pa.s to 6,000 Pa.s (3000 to 6000 centipois) at a temperature (25 ° C), and a pH in the range of 6 to 7. Tests at high temperature storage have been carried out and the shampoos thus prepared have been shown to be stable and do not exhibit appreciable decomposition or excretion of the components due to storage. When tested for hair conditioning properties by the tests described in the description, it has been found to be good conditioning shampoos, all of which are better than the shampoos to be compared which do not contain the water-insoluble conditioning agents of the invention. Each treatment composition prepared according to the described procedures of Example 1 is better or at least the same compared to all commercial treatment shampoos on the market, and the shampoo according to Procedure 1C even has measurable and substantially better conditioning properties than these commercial products.

If the addition of anionic detergent is omitted from the 1C preparation process of the hair conditioning (and fiber conditioning) composition, the result is a composition suitable for treating fibrous materials and can also be used as a hair dressing. Although the product will be flushed with water (in both cases of application), the treated fibrous material will have less static charge, will be soft and pliable to the touch, and will have a shiny and attractive appearance. If human hair is treated this way, it will also be much less exposed to unpleasant flying and make combing and styling easier.

In other modifications of Example 1, where, for example, the 30C chain is omitted and replaced with deionized water, the shampoo tends to become unstable and disintegrate into different phases and / or excretion of the components at elevated storage temperature. Also, the hair conditioning effect is not so good and the pearlescent effect is either not produced at all or is diminished and less attractive.

If Aminosilicones A in the composition of Processes 1A and 1C are replaced with conventional non-volatile silicones or aminosilicones, then the modifying effect of these processes will be substantially reduced (but will still be present). These effects can be enhanced by the addition of 1 wt. Ammnosilicon A instead of 1 wt. that is, the percentage of Aminosilicones A is increased to 2.50% by weight, which is equal to the amount in process 1A. Similarly, if 2.50 wt. Aminosilicones A instead of the same amount of water (percentage) then the conditioning effects also increase significantly.

The shampoo compositions of this example are prepared as described in Example 1 as well as in the description. It has been found that all shampoos thus prepared have an attractive pearlescent appearance and are stable under elevated temperature storage conditions. In addition, it is the excellent shampoo hair that equals or exceeds the hair shampoo properties of the best commercial shampoo hair that the market provides. Compositions having compositions 2A and 2B have the same conditioning properties and are superior to 2C.

The prepared shampoos have an attractive pearlescent appearance and are stable when stored at elevated temperatures. In addition, the 10 hairs have enhanced conditioning properties, wherein the composition of composition 3B has even better conditioning properties than the composition of composition 3A. If we increase the amount of Aminosilicon A and Unilin 425 to 2.50 wt. % and 2.00 wt. at the expense of deionized water, then the conditioning properties will further increase, while the stability and pearlescent appearance will still be excellent.

The compositions of this example were prepared in the same manner as in Examples 1-3. The resulting products containing a long chain alcohol or derivative of the type described herein, which improves conditioning and stabilizing properties and gives the shampoo a pearlescent appearance. These are attractive pearlescent liquids having a pH in the range of 6 to 7 and a viscosity ranging from 3,000 Pa.s to 6,000 Pa.s (3000 to 6000 centopois) at a temperature (25 ° C). All of these compositions have higher stability compared to compositions which do not contain a long chain alcohol or derivative thereof, and are excellent cleansing and hair conditioning agents. It has already been noted that preferably alcohols with an average chain length corresponding to 30 carbon atoms are used, as well as an average chain length of C ₄₀ and ethoxylate alcohols with the same chain length.

The composition of process 4C also does not contain resins and petrolatum which is used for the initial treatment of aminosilicones, long chain alcohols, or a derivative thereof, and a higher fatty acid triglyceride (Syncrowax). The best conditioning and stabilizing effects were achieved with 4C, but all four compositions are superior conditioning shampoos compared to the best conditioning shampoos on the market (the required conditioning, stability and appearance required).

Example 5

In Examples 1-4, mixtures of ammonium lauryl sulfate and sodium lauryl ethoxysulfate were preferably used; similar results can be obtained by using other higher alkyl sulfates, such as the sodium or triethanolammonium salts of C 14-18 alkylsulfonic acids. Similarly laurylethoxysulfát sodium may be replaced by C ₄ _ig ethoxysulfátem sulfate wherein the ethoxy group has 1 or 2 to 5 or 6 carbon atoms, preferably 3, and sodium is replaced by ammonium or triethanolamine. In the same way, distearlydimethylammonium chloride can be replaced by another quaternary ammonium salt, for example tricetylmethylammonium bromide or chloride, dilauryldiethylammonium chloride and sometimes trimethylstearylammonium chloride or the corresponding talloyl compounds (alkyl is obtained from beef tallow). Other materials included in the specification, including other long chain ethoxylated primary alcohols containing an average of 24 to 40 carbon atoms and their corresponding esters and acids, may be used to further alter other water-insoluble hair conditioners. Various additives may replace those listed in the compositions of the examples. For example, the monoethanolamide may be replaced by the mono- or diethanolamide of lauric acid or myristic acid, respectively, or the corresponding cocoalkanolamide, or the corresponding isopropanolamide, including EDTA and hydroxylated with ethylcellulose, methylcellulose or other suitable resins and thickeners. The compositions thus prepared will be of high quality and sufficiently conditioning, stable and attractively pearlescent shampoos with the desired viscosity and pH. Likewise, by omitting the anionic detergent (s) from the composition, it is possible to obtain dressing dressings and fiber dressing compositions having similar properties and sufficient treatment of fibrous material such as hair. Such a composition may be in liquid form or in the form of a gel, paste or cream.

This is essentially the same preparation as described above. First, the components of Part I and Part II are mixed separately, followed by mixing at 90 ° C, followed by the sequential addition of Parts III and IV, wherein the mixing of Part IV takes place at room temperature. The shampoos thus prepared have a pearlescent appearance and the desired viscosity and pH. Washing hair with both of these shampoos is as good or better than the most effective shampoo hair found on the US market.

In the above compositions, the amount of Aminosilicone A is considered to be the amount of pure aminosilicone, although dilute silicones are used, and still a portion of the solvent into three portions of silicone (this applies to all examples). The use of a solvent reduces the viscosity of the silicones. Likewise, the ammonium phosphate buffer may comprise up to about 0.20 wt. of these compositions.

In a modified composition, using Unilin 550 or a pure saturated linear alcohol having a chain length of 30 to 36 carbon atoms or mixtures thereof, instead of Unilin 425, equivalent results are obtained. The further enhancement of the conditioning properties can be achieved by introducing quaternary ammonium salts into the composition of the mixture, for example distearyldimethylammonium chloride and other conditioning agents, for example microcrystalline wax, petrolatum, polyethylene and beeswax. Also, amino silicones can be replaced by non-amino silicones and dimethycones, such as the silicones of U.S. Pat. No. 4,704,272 and other non-volatile (preferably) water-insoluble silicones.

Example 7

The compositions of the examples can be further modified by varying the amount of the individual components by ± 10%, ± 20%, ± 30%, although the amount remains within the above limits, and the compositions thus obtained are stable pearl shampoos and hair conditioning products. with increased hair conditioning and fiber conditioning properties. If these products are used for hair shampooing or are used as hair dressing hair, according to the method described in the description, which comprises applying to fibrous material or hair, often in the presence of added water, and then rinsing, then the hair so treated is sufficiently

-18GB 286571 B6 cleaned and adjusted. They are much easier to brush both wet and dry, accumulate considerably less electrostatic charge and are easy to edit and soft to the touch.

The compositions of the invention, which have been described in the examples, are of considerable benefit in the field of fiber treatment and hair treatment. Using the described long-chain primary alcohols, which are preferably fully saturated alcohols, or derivatives thereof, in conjunction with the disclosed water-insoluble conditioning agent (s) (and cationic surfactant), compositions with substantially improved hair conditioning properties can be prepared, such as shampoos having either as good or better properties than such compositions that the market provides. This could be achieved using the long chain alcohols or derivatives thereof such as Unilins and Unitoxy, which are available materials, but were not known as components of hair conditioning compositions and shampoos.

The invention has been illustrated in the foregoing with reference to exemplary embodiments, which are provided by way of illustration only and are not intended to limit the scope of the invention as defined by the claims.
