Description

Technical field

The invention relates to fiber conditioning compositions. In particular, the invention relates to hair conditioners, in particular shampoos, which are useful for washing human hair. At the same time, hair washing with these shampoos results in a hair treatment, after which the hair is compliant (easily combed and has a relatively low electrostatic charge) and the conditioning effect thus obtained is more intense than with conventional shampoos previously known.

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 already been suggested as hair dressing agents. These substances have been designed with the same aim in hair shampoos. Various silicones and other water-insoluble conditioning agents have also been proposed, including waxes, fats and oils. These shampoos have heretofore been produced in solid, gel, cream and liquid form, the liquid shampoo form comprising solutions, emulsions, suspensions or dispersions. When shampoos are in the form of emulsions or suspensions (or dispersions), the ingredients sometimes separate during storage, which may be detrimental to their commercial success. A shampoo composition comprising a quaternary ammonium compound, a surfactant compound and an aminosilicone is disclosed in European Patent 152,194. A liquid detergent composition containing siloxane derivatives is the subject of U.S. Patent 4,639,321.

The method of treating the fibrous material is carried out by applying an amount modifying fiber of the composition of the invention to this material, to which the fibrous material composition is rinsed, leaving the modifying agent on the fibrous material.

The method of shampooing and conditioning the hair comprises applying the shampooing and conditioning amount of the shampoo of the invention to human hair or to the head and rinsing the shampoo from the hair leaving the conditioning agent on the hair.

The shampoo of the invention may be prepared in liquid, cream, gel or paste form and only need to contain water-insoluble conditioning agent and saturated long-chain primary alcohol in an aqueous medium, preferably cationic conditioning agent (which is also present) it also acts as a surfactant, but will only be considered here as a conditioning agent). In some ways of stabilization,

Which are efficiently carried out using long-chain saturated primary alcohols (the term "or derivatives" will be omitted hereinafter for ease of expression), their presence is not absolutely necessary, but other advantages of these compounds, such as pearlescent effect and refinement, these compounds. Water-soluble organic synthetic detergents, preferably anionic detergents, more preferably higher alkyl sulfates and / or higher alkyl ethoxy sulfates will also be 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 fiber conditioning agents are those which preferably comprise: organosilicon compounds, for example non-volatile silicones (especially aminosilicones), containing dimethicones, polyethylenes, paraffins, petrolatum, microcrystalline waxes, _C18 . ₃₆ fatty acids and their corresponding triglycerides, stearyl stearate, and quaternary ammonium salts and amines (which are classified here as surfactants rather than surfactants, although acting as both). Organosilicone compounds and silicones can be used, which are used as conditioning agents for fibrous materials, many of which have been described in the aforementioned patents and applications. It has been found that amino acids are usually more effective conditioning agents in the compositions of the invention, such as conventional silicones and aminosilicones of this type, with aminosilicones of the general formula most preferred for use.

Preferably x in said formula is in the range of 200 or 300 to 10,000, more preferably in the range of 500 to 10,000, and most preferably in the range of 750 to 800 or 850, for example about 800 and y represents a value ranging from 0 to 8, more preferably less than 3 and most preferably equal to one. The amine equivalent of such an aminosilicone is preferably in the range from 5,000 to 50,000, more preferably from 10,000 to 40,000. The molar proportion of amines in the specified preferred aminosilicones used in the experiments referred to in this specification is about 0.125 percent, the degree of polymerization being about 800, x equals 797, y equals one, and the molecular weight can be about 60,000. Since the molecular weights of high polymers sometimes vary depending on the measurement technique used, it has been suggested that a basic reference to the measurement technique could be given, which was used in the present case to identify amino silicones, rather than relying on a given molecular weight. Preferably, the disclosed amino silicones are provided by Dow Coming Corporation and are referred to in the Examples as Dow Coming Aminosilicone A.

Polyalkenes which can be used as water-insoluble conditioning agents in the 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 generally be used as the alkylene of these polymers, each having 1 to 5 carbon atoms, preferably 2 to 3 carbon atoms, and having a molecular weight in the range of 1000 to 10,000 or more under certain conditions, usually ethylene and / or propylene are used, and indeed most often ethylene (polyethylene) is used.

The paraffins that may normally be used are paraffins having a chain length of 20 to 50 carbon atoms, preferably having 20 to 40 carbon atoms, and isoparaffins may have a chain length in the range of 12 to 16 carbon atoms, preferably 13 to 14 carbon atoms. Petrolatum is a technical petrolatum whose melting takes place at a temperature of 38 to 60 ° C. Microcrystalline waxes have an average molecular weight ranging from about 500 to 800 (about twice as much as with paraffins). C _{) 8} . _The fatty acids and their corresponding triglycerides are the higher fatty acids and triglycerides provided by Croda Chemical Corporation (under the tradename Syncrowax HGL-C, which is a triglyceride product). The stearyl stearate, which represents esters of higher fatty acids and higher fatty alcohols, is provided by Inolex Corporation as Lexol SS.

Cationic conditioning agents (which may also be considered as secondary (secondary) conditioning agents in the conditioning compositions of the invention) are preferably represented by quaternary ammonium salts, although other cationic compounds that have fiber conditioning properties, at least in part, may also be used. Thus, known amines, amine salts, imidazoline salts and betaines, as well as the cationic materials described in U.S. Pat. No. 4,000,077, may be replaced by at least partially a quaternary ammonium salt, may be assembled with cationic anionic surfactants as described in U.S. Patents 4,896,422 and 4,888,119 and in patent application SN 06 / 916.069.

R ⁹ , R ¹⁰ , R ¹ , R ¹² , N ⁺ , X 'represents the formula of a preferred quaternary ammonium salt, wherein R 6 is an alkyl group when at least one of the R groups is lower alkyl and at least one is higher alkyl, the other R the groups represent higher and / or lower alkyl. Preferably R ^{9 is} lower alkyl and has 1 to 4 carbon atoms, while R ¹⁰ and R ¹¹ are higher alkyls having 10 to 40 carbon atoms, R ¹² is then higher or lower alkyl X is a salt-forming anion such as a halide , a lower alkosulfate or a lower carboxylic acid radical, for example, chloride, bromide, metosulfate, etosulfate, citrate or acetate. Lower alkyl will preferably have 1 to 3 carbon atoms, more preferably 1 to 2 carbon atoms, and most preferably methyl will be used, while higher alkyl will preferably be 10 to 22 carbon atoms, more preferably 12 to 18 or 20 atoms carbon and most preferably C 14 to C 18, for example C 16 or C 18. The anion is preferably a halogen such as chlorine, bromine or iodine, preferably chlorine and bromine and most preferably chlorine.

The number of lower alkyls in the quaternary nitrogen will preferably be 1 or 2, and the higher alkyls will preferably be 2 or 3. Such compounds thus have 2 or 3 long chain alkyls containing 12 to 20 carbon atoms and 1 or 2 short chain alkyls it contains 1 or 2 carbon atoms. The quaternary ammonium salt has been found to contain at least 30 carbon atoms and preferably at least 34 carbon atoms. Most preferred higher alkyl is cetyl and stearyl and most preferred lower alkyl is methyl. More preferably the quaternary ammonium halides include tricetylmethyl-ammonium chloride and distearyldimethyl-ammonium chloride, but other quaternary ammonium salts such as dicetyl-dimethyl-ammonium chloride and tristearylmethyl-ammonium chloride and the corresponding amines, previous U.S. patents. Such cationic surfactants and complexes may be used at least as part of the cationic surfactant included in the composition of the invention.

The primary long-chain alcohols which are part of the compositions of the invention are usually preferably saturated hydroxyl-terminated compounds. The distribution of such alcohols equals 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, that is, the fiber conditioning stabilization deteriorates and the pearlescent effect diminishes, while if the chain length is greater than 45 carbon atoms, on average about 50 carbon atoms, such alcohols are then unable to disperse satisfactorily in the compositions. In addition, said long chain alcohols may be replaced by at least partially related compounds such as the corresponding alkoxylated alcohols of the corresponding fatty acids and saturated primary long chain alcohol esters. Of these "derivatives", ethoxylated alcohols are preferred and most preferred are ethoxylate alcohols, which will usually contain up to 20 ethoxy groups per mole, for example 10 to 20, with the alcohols which are a preferred embodiment of the invention usually used alone or in admixture with related compounds of the “derivative” family, where alcohol accounts for the majority of the total “alcohol and derivative” content. Petrolite Corporation manufactures and sells through the Petrolite Specialty Polymers Group commercial materials that can be used in the compositions of the invention and are sold under the trade name Unilin ™ - Alcohols as also described in the corresponding technical bulletin.

Such alcohols may be 75% to 90%, for example 80% to 85%, and weigh equal to the weight of the saturated hydrocarbons of the corresponding chain length. The distribution curve of the alcohols of such products is essentially bell-shaped, with no alcohol chain length represented more than 10% of the total content 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. The alcohols present and the corresponding hydrocarbons are typically at least 80% alcohols (and the corresponding hydrocarbons) having a chain length of 18 or 20 to 54 carbon atoms, the alcohol having an average of about 30 carbon atoms being at least 60% alcohol having a chain length of from 18 or 20 to 44 carbon atoms, and if the alcohol has an average of about 40 carbon atoms, at least 80% is comprised of chain lengths of from about 28 or 30 to 54 carbon atoms. Examples of long-chain primary alcohols are Unilin-425, which has an average of 30 carbon atoms in its chain, Unilin-550, which has an average of 40 carbon atoms, and Unilin-350, which has 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 being ethylated with up to 20 ethoxy groups, for example 13 ethoxy groups.

The water-soluble synthetic organic anionic detergent is usually represented by a lipophilic sulfate or sulfonate, but other hydrophilic groups such as phosphate and phosphonate may also be used. The cation-forming salt of such compounds is usually represented by an alkali metal, ammonium or alkanol-amine, preferably sodium and ammonium salts. It is further preferred to use a lipophilic sulfate or a mixture of sulfates for the anionic detergent. As the lipophilic anionic detergent, an alkyl group, preferably a higher C12-18 fatty alkyl will be used, although a wide range of alkyls of 10.8 and 6 or up to 18 or 20 carbon atoms may also be used. Such detergents have been shown to be most compatible with the shampoos described and provide good cleaning and conditioning properties while not disturbing the pearlescent and conditioning effect of the composition. Desired detergents are in particular ammonium lauryl sulfate and sodium lauryl ethoxy ether having 1 to 6 ethoxy groups per mole, preferably 2 or 3 ethoxy groups per mole.

The preferred anionic detergents described above may be at least partially replaced with other such detergents as disclosed in McCutcheon ' s Detergents and Emulsifiers, North American Edition, issued in 1984. Furthermore, the use of amphoteric and ampholytic detergents may sometimes be required in such compositions. zwitterionic zwitterionic and relatively less nonionic detergents. These detergents are also disclosed in the publications and references are part of this invention (also see the description of suitable detergents in S.N. 07 / 432,952).

Sometimes a relatively small amount of such a surfactant may be used, and the term is used herein in a broad sense, and includes various emulsifiers and dispersants (for use in non-hair shampoo conditioners and fiber conditioning compositions).

For these preferred detergent combinations mentioned, they are a combination of a higher fatty alkyl -

sulphate and higher fatty alkyl ethoxylate sulphate, the preferred ratios being 2: 1 to 8: 1 (alkyl sulphate: alkyl-

(ethoxy sulfate) and it is preferred that the alkyl sulfate is an ammonium salt and the alkyl alkoxysulfate is a sodium salt. While each such detergent may be used alone, and in some preferred formulations, the ethoxylate detergent is omitted.

The various required components of these compositions are dissolved and / or form an emulsion and / or suspension in an aqueous medium. Such an environment may comprise various non-abrasive fiber conditioning compositions and shampoo composition ingredients known in the art, however useful it may be mentioned in greater detail, since these are particularly desirable components of said composition and contribute significantly to the desired properties. Higher fatty alkanolamides have long been known as blowing agents and foam stabilizers. These compounds usually have 12 to 16 carbon atoms in the acyl group that has reacted with a lower (1 to 3 carbon atoms) mono- or dialkanolamine. The best alkanolamide in said formulations is considered to be lauric monoethanolamide or coconut diethanolamide, which has about equivalent effect, and other blowing agents and foam stabilizers such as betaines and related materials may also be used. Various resins and other thickening materials are also useful for shampoo compositions, but it has been found that the best of these in the compositions are hydroxyethylcelluloses. These celluloses are supplied by Aqualon Corporation under the trade name Natrosol, preferably Natrosol 250 HHR and Natrosol 330 CS are used in the blend, the content of the first being 2 to 5 times greater than the content of the second. Although hydroxyethyl cellulose is preferably used, it can be replaced at least in part by, for example, a synthetic resin and thickeners such as methylcellulose, hydroxypropylmethylcellulose, Polyquaternum ™ - 10, modified starches and natural resins.

And thickeners such as guar gum, 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 that solubilizes polyethylene and aids in its dispersion, should the dispersion in the composition be insufficient, phase separation would occur and the hair conditioning effect would be small.

Other ingredients that can be used in the compositions include: ethylene glycol monostearate, ethylene glycol distearate and propylene glycol distearate, all substances having pearlescent properties, viscosity regulators such as propylene glycol and sodium chloride, pH adjusting agents such as citric acid and citrates sequestering agents such as EDTA (ethylenediaminetetraacetic acid), antifreeze agents such as propylene glycol, solvents such as ethanol and isopropanol, preservatives and antioxidants such as Germaben II (Sutton Laboratories), zinc pyrition reagents, or Climbazole ™ (see US 4, 867,971) and finally dyes and perfumes. The water used to prepare the aqueous environment may be present not only in liquid preparations 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 (as calcium carbonate). In some cases, water with a hardness of 200 ppm can also be used, but will usually try to avoid this.

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 will range from 1 to 35% by weight, preferably from 2 to 35% by weight, for both conditioning compositions, for example hair dressings and shampoos. and most preferably from 3.5 or 8 to 25% by weight, with a lower range for the conditioning compositions and a higher shampoo. That is, the shampoos are generally comprised of 5 to 35 wt%, preferably 8 to 25 or 35 wt%, and most preferably 10 to 20 wt%. The alkyl sulfate-alkyl ethoxylate sulfate content of the shampoos is usually 5 to 25 wt%. %, preferably 10 to 20 wt.%, and most preferably 10 to 15 wt. and up to 15 wt.%, preferably 0 or 1 to 10 wt. % and more preferably 0 or 1 to 5 wt. of said reagent. If each such sulfate detergent is used alone, then the percentages given for alkyl sulfate apply.

The water-insoluble conditioning agents (a) (which do not include surfactant cationic agents) are represented in a bird ratio by ensuring, alone or in conjunction with cationic surfactants, that the treatment of the fibers or hair is sufficient. That is, they are present in an amount of 0.3 to 10 wt. in both compositions and fibers conditioning both shampoo. Preferably, their content is 0.3 to Ί% and most preferably 0.3 to 5%. Thus, the cationic surfactant content of the fiber conditioning compositions as for shampoos is usually from 0.1 to 5%, preferably from 0.1 to 3%, and most preferably from 0.1 or 0.3 to 0.7 or 1% by weight. The saturated primary long-chain alcohols or derivatives thereof are present in an amount of 0.5 to 10%, preferably 0.5 to 5 or 6% and more preferably 1 to 5% by weight. The aqueous content (which may contain various additives) will be usually between 75 and 99%, the aqueous content of such a shampoo being 60 to 90%, preferably 63 to 85%, and more preferably 63 to 80% by weight. The water and the aqueous medium may be adjusted depending on the desired proportions of ingredients present. in the composition. Typically, the ratio of the contents of the saturated long-chain primary alcohols and / or derivatives thereof and the conditioning agent (s) ranges from 0.2 to 5, preferably from 0.3 to 3, with a ratio of 0.5 to 2 and about 1 is more preferred and most preferred.

The proportions of the ingredients in the various shampoo compositions of the invention may be within the ranges indicated, as indicated by the following more complex types of preferred compositions, with the proportions of the proportions of the ingredients contained therein.

In a shampoo containing a lipophilic sulfate, a quaternary ammonium salt, an aminosilicone, and a saturated long-chain primary alcohol in water, typically 5 to 18% fatty alcohol alcohol, preferably its ammonium salt, 0 or 1 to 10% fatty alcohol ether sulfate, preferably its sodium salt are present. the range of ratios may be 1: 10 to 10: 1), 0.2 to 2% by weight of a quaternary ammonium salt, 0.5 to 10% by weight of an aminosilicone, 0.5 to 5 or 6% by weight of a long-chain saturated primary alcohol % of chain and / or derivatives thereof, 65 to 85 wt. water and part of the weight are shampoo ingredients. Preferred ranges are 10 to 15% or 20%, 0 or 1 to 5%, 0.1 to 0.7, 0.8 to 4%, 1 to 5.0% and 63 to 80% by weight. also contain 0.2 to 2 wt. hydroxyethyl cellulose (or other suitable reinforcing agent), 2 to 5 wt.% lauric monoethanolamide or diethanolamide, 0 or 0.5 to 2 wt.% microcrystalline wax, and 0 or 0.5 to 1 wt.% petrolatum.

For further such compositions, the first six ranges will be the same as those just mentioned, but will also contain 0.3 to 2% polyethylene and 0.3 to 2% mineral oil, preferably 0.5 to 1.5%, respectively. Furthermore, hydroxyethylcellulose and lauric monoethanolamide are present in the same proportions as mentioned in the previous formulations, as opposed to paraffin wax and isoparaffin, whose ranges are 0.1 to 2%. %, preferably 0.1 to 1%, and 0.1 to 2%, preferably 0.1 to 0.5%, all in wt.

According to a further embodiment of the invention, the shampoo comprises polyethylene as the hair conditioning agent together with a quaternary ammonium halide and a high molecular weight lipid solubilizing agent (e.g., mineral oil) for solubilizing polyethylene, wherein the component ratios are the same as the aforementioned anionic detergent ratios, cationic a 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%, while the amount of polyethylene and mineral oil will generally be 0.3 up to 2% of each and preferably will be in the range of 0.5 to 1.5% and 0.5 to 2%, respectively, all in% by weight. The composition also contains important desirable components, including hydroxyethylcellulose, in the range of from 0.2 to 2%, on 2 to 5% lauric acid monoethanolamide, further 0.1 to 1% paraffin wax and finally 0.1 to 0.5% isoparaffin, all in% by weight.

In another shampoo according to 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 those of the first of these formulations, except that they are present. the long-chain saturated primary alcohol (which may contain derivatives thereof) preferably contains 0.5 or 1 to 2 or 3% of chains with an average length of about 30 carbon atoms and up to 2 or 3% of chains with an average length of about 40 carbon atoms. 0.5 to 1 wt. % of a long chain polyethoxylated saturated primary alcohol (derivative), wherein the alcohol has about 40 carbon atoms on average and is 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) can be supplemented with 2-5% lauric monoethanolamide, 0.5-2% Cu triglyceride. % Of an acid and 0.1 to 0.5% citrate, all in% by weight, preferably sodium citrate. A further modification of the preceding formulation comprises 0.1-1% paraffin wax and 0.5-1.5% by weight of hair styling agents. % solid polyethylene having a molecular weight ranging from 1000 to 4000 and with 0.5 to 2 wt. mineral oil having a molecular weight of from 300 to 800, which has the function of a solvent and polyethylene.

Such compositions may additionally comprise 2 to 5% lauric monoethanolamide, 0.2 to 2% hydroxyethylcellulose, 0.5 to 2% microcrystalline wax, and 0.5 to 1%, all by weight, of petroleum jelly. Instead of microcrystalline wax and petroleum jelly, 0.5-1.5% by weight of the polyethylene described above and 0.5-2% by weight can be used. of the mineral oil described.

For the gels, pastes and thickeners of the present invention, the amount of optional and adjuvant components is required to be within the same ranges as in the aqueous compositions, the amount of water usually being reduced to sometimes from 30 to 40%. In some examples, water may be replaced up to 50% by another solvent, for example ethanol or isopropanol, but it is usually not more than 20%, all by weight.

Although the fiber conditioning and hair conditioning compositions may be in the various physical forms mentioned above, a liquid form is preferred for them and the most preferred method of the invention is a liquid hair shampoo. To be marketable, these compositions must be chemically and physically stable. Their effects should not deteriorate below acceptable levels by storage, and should not contain components that fall out or phases that are eliminated during storage. The aforementioned primary long-chain alcohols (of the Unilin or Unitox type) stabilize the composition of the invention and, in addition, give the compositions an attractive pearlescent appearance and increase the effect conditioning fibers. Such shampoos also have the desired viscosity to be able to flow, but are no longer thin enough to flow uncontrolled. The desired viscosity is in the range from 1 to 15 Pa.s at room temperature (26 ° C), preferably from

Pa.s to 6 Pa.s. The shampoos according to the invention are not deposited and separated and do not deteriorate or deteriorate by storage as demonstrated by accelerated temperature aging tests. The viscosity of shampoos 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 providing a shampoo with a certain viscosity that allows for some expected change in viscosity before use.

The enhancement of the hair conditioning effect achieved using the compositions of the invention, when compared to the cases where the said conditioning agents have been forgotten, is already evident to the casual consumer of the shampoo or the conditioning compositions of the invention and is measurable in standard tests used to evaluate the treatment and its components. that include ease of wet combing, ease of dry combing, ability to maintain hairstyle, static charge suppression and flying. An accidental shampoo user must state that after shampooing the hair is easier to brush in both wet and dry conditions compared to hair treated with a shampoo other than the shampoo of the invention (in which the conditioning components or some of the shampoos have been omitted). them). Scientific tests have also shown that the force required to move the comb through 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 through the hair that has been treated with the comparator. These results were confirmed by panel tests when the experimental and comparative products were evaluated blindly, assessing the ease of combing, the 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 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 ten 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 g 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 commonly from five to ten grams per disposable. The applied conditioning composition can be combed into all hair with a comb or brush and subsequently washed, it is also possible to leave the composition in the hair or 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, after which the composition is removed from the hair with water and then combing, drying, drying and brushing or brushing wet hair for the desired hairstyle.

The preparation of said compositions, including shampoos, need not be complicated, but in order to achieve better stability and pearlescent effect and the best conditioning effect upon storage of the compositions of the invention, it will be desirable to disperse the water-soluble lipophilic sulfate and / or sulfonate detergent (s). at elevated temperature, i.e. at about 70 to 95 ° C, separately prepare the melt or liquid mixture by dissolving a dispersion of a cationic conditioning agent, which is an ammonium salt (may be omitted) in some lipophilic material, such as hydrocarbons containing polyethylene, mineral oil , microcrystalline

Wax, technical petrolatum, paraffin and isoparaffin, long-chain alcohol, triglyceride and stearyl stearate, at elevated temperature. After mixing the two mixtures at said elevated temperature, heated aminosilicones may be admixed to the resulting mixture (which may sometimes also include lipophiles), the mixing of the different parts being carried out at approximately the same temperature. Sometimes it is desirable that the amino silicones be mixed into the master premix, which increases the stability of the product. If the water-soluble and / or solubilizable ingredients present are present, they may be admixed to the aqueous phase of the material, but if they are neither soluble nor solubilizable in water, they may be mixed into lipophilic materials such as hydrocarbons or may in some cases be added to mixtures 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 amino silicones before cooling. The reason for adding the parisons to the cooled mixture is to avoid their loss due to evaporation of their constituents 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 may be produced which may decompose upon storage or phase separation, and these unstable compositions tend to have worse conditioning properties than the stable conditioning compositions and shampoos prepared according to the process of the invention.

The following examples illustrate but do not limit the invention. Unless otherwise stated, all parts in the examples, the other part of the description and the claims are by weight and temperature in degrees Celsius.

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

The products thus prepared are attractive pearlescent liquid shampoos having a viscosity ranging from 3 to 6 Pa.s at 25 ° C and a pH ranging from 6 to 7. Elevated temperature storage tests have been carried out and have been shown to be as follows: the prepared shampoos are stable and do not undergo appreciable decomposition or excretion of the components due to storage. In testing the hair conditioning properties by the tests described in the description, they have been found to be good conditioning shampoos, all of which are better than the comparative shampoos which do not contain the water-insoluble conditioning agents of the invention. Each conditioning composition prepared according to the described procedures of Example 1 is better or at least the same as all commercial conditioning shampoos on the market, and the IC shampoo has even measurable and substantially better conditioning properties than these commercial products.

If the addition of an anionic detergent is omitted from the IC 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 spill. Even if the product is rinsed with water (in both cases of application), the treated fiber 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 in this way, it will also be much less exposed to unpleasant flying and their combing and adjustment will be easier.

In other modifications of Example 1, when, for example, in the IC process, the long-chained alcohol is omitted and replaced with deionized water, the shampoo then tends to become unstable and disintegrate into different phases and / or excretion of ingredients at elevated storage temperature. Also, the hair conditioning effect is not as good and the pearlescent effect is either not produced at all or is diminished and less attractive.

If the amino silicones A in the composition of process IA and 1C are replaced by conventional non-heating silicones or aminosilicones, then the modifying effect of these processes will be substantially reduced (but still present). These effects can be enhanced in the IC process by further adding 1% aminosilicone A instead of 1% deionized water, i.e. the percentage of aminosilicone A is increased to 2.50%, which is equal to the amount in method IA. Similarly, if 2,50% of the aminosilicone A is added to the composition of process 1B instead of the same amount of water (percent), the conditioning effects also increase substantially.

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

The shampoo compositions of this example are prepared in the same manner as described in Examples 1 and 2 and in the description section (as well as US Patent Application No. 07 / 432,952). Both shampoos thus prepared utilize, as water-insoluble conditioning agents, saturated primary long-chain alcohols of the Unilin 425 type in conjunction with C ₁₈ triglycerides. ₃₆ (mixed), aminosilicones and polyethylene or with aminosilicones only, with microcrystalline wax and technical petrolatum. Prepared shampoos have an attractive pearlescent appearance and are stable when stored at elevated temperatures. In addition, they have elevated hair 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 Aminosilicone A and Unilin 425 to 2.50% and 2.00%, respectively, at the expense of deionized water, the conditioning properties will further increase, while the stability and pearlescent appearance are still excellent.

The compositions of this example were prepared in the same manner as in Examples 1-3 and in patent application SN 07 / 432,952. 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. They are attractive pearlescent liquids having a pH in the range of 6 to 7 and a viscosity in the range of 3 to 6 Pa.s at 25 ° C. All compositions have a higher stability than compositions which do not contain long-chain alcohol or a derivative thereof and are excellent cleansing and hair conditioning agents. It has already been noted that preferably alcohols having an average chain length corresponding to 30 carbon atoms, furthermore an average chain length of C ₄₀ and ethoxylate alcohols of the same chain length are preferably used.

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

Example 5

Mixtures of ammonium lauryl sulphate and sodium lauryl ethoxysulphate were preferably used in Examples 1 to 4, similar results can be obtained when using other higher alkyl sulphates such as sodium or triethanolammonium C14 salts. g of alkylsulfonic acids. Similarly, sodium lauryl ethoxysulfate can be replaced by CC ₁₄ . ₁₈ ethoxysulfate sulfate, wherein the ethoxy - group has 1 or 2 to 5 or 6 carbon atoms, preferably 3, and the sodium is replaced by ammonium or triethanolamine. In the same way, distearyl dimethylammonium chloride can be replaced by another quaternary ammonium salt, for example tricetylmethylammonium bromide or chloride, dilauryldiethylammonium chloride and sometimes also trimethylstcarylammonium chloride or the corresponding tallow compound (alkyl). Other materials included in the specification including other ethoxylated long-chain primary alcohols containing an average of 24 to 40 carbon atoms and their corresponding esters and acids may be used to further vary 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 miristic acid, respectively, or the corresponding cocoalkanolamide, or the corresponding isopropanolamide, EDTA may also be included and hydroxylated ethylcellulose may be replaced by hydroxylate propylmethylcellulose, methylcellulose or other celluloses. The compositions thus prepared will be of high quality and sufficiently conditioning, stable and attractive 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. The separate components of Part I and Part II, respectively, are mixed first, followed by mixing at 90 ° C, followed by the sequential addition of Parts III and IV, with mixing of Part IV 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 undiluted silicones are used, one part of the solvent per three parts of the silicone (this applies to all examples). The use of a solvent reduces the viscosity of the silicones. Likewise, the ammonium phosphate buffer can constitute up to about 0.20% of these compositions.

In a limited composition, when Unilin 550 or a pure unsaturated linear alcohol having a chain length of 30 to 36 carbon atoms or mixtures thereof is used instead of Unilin 425, equivalent results are obtained. Further enhancement of the conditioning properties can be achieved by introducing a quaternary ammonium salt 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 may be replaced by non-amino silicones and dimethicones, 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% by weight, although the amount of these components remains within the above limits, and the compositions thus obtained are stable pearl shampoos and hair conditioning products. increased hair conditioning and fiber conditioning properties. If these products are used for hair shampooing or 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 cleaned and edited. They are much easier to brush in the wet than in the dry, accumulate significantly less electrostatic charge and are easy to edit and soft to the touch.

SK 281337-6

The compositions of the present invention, which have been described in the examples, are of significant benefit in the field of fiber treatment and hair treatment. Using the described long-chain primary alcohols, which are preferably totally saturated alcohols, or derivatives thereof in conjunction with the described water-insoluble conditioning agent (s) (cationic surfactant), it is possible to prepare compositions with substantially improved hair conditioning properties, such as are shampoos that have either as good or better properties as those compositions provided by the market. This was 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 by examples, which are not to be construed as limiting the scope of the invention, which is clearly defined by the definition of the claims. It will be understood that embodiments of the invention may be modified by those of ordinary skill in the art without departing from the scope of the invention.
