DD295308A5 - FIBER CONDITIONING COMPOSITION, METHOD FOR THE PREPARATION AND USE THEREOF - Google Patents

Abstract

A fiber conditioning composition particularly suitable for conditioning human hair on the head contains a cationic surface active fiber conditioning agent such as a hair conditioning quaternary ammonium halide, a normally solid and water insoluble poly-lower alkylene such as polyethylene, and a hydrocarbon solubilizer this poly-lower alkylene such as mineral oil, which liquefies it and renders it water dispersible in the presence of the cationic surface active fiber conditioning agent and water. The composition exhibits significantly improved fiber conditioning activity as compared to control compositions containing the cationic surface active conditioning agent alone. In a preferred embodiment, the fiber conditioning composition contains water and an anionic surfactant and is a shampoo for human hair. The invention also relates to methods of conditioning fibrous materials including shampooing human hair and conditioning it so as to enhance nasal caulking, dry caulking and handleability, and to reduce the electrostatic charge thereon and inadvertent escape. The invention also encompasses methods of making the inventive composition and shampoos.

Description

Application blot of the invention

The invention relates to fiber conditioning compositions. In particular, it relates to such compositions which are shampoos containing liquefied poly-lower-alkylene or poly (lower) alkylene and which leave shampooed hair better conditioned (easier to comb, easier to handle and with less electrostatic charge) after shampooing.

Characteristic of the known technical solutions

Fiber conditioning compositions such as compositions for treating washed fiber materials incorporating fabric softeners that condition washed fabrics, making them softer and less prone to receive electrical charges after drying in a dry booth, include cationic conditioning agents such as quaternary ammonium halides; Such quaternary ammonium compounds have also been incorporated into hair rinses. Polyethylene has also been used in preparations for treating fibrous materials including human hair, sometimes as a lubricant for these materials. Mineral oil has also been used as a lubricant and as a shine agent for fibers including hair. Similarly, these materials have been incorporated into shampoos, some of which are anionic surfactants.

However, it has not heretofore been known that a normally liquid hydrocarbon such as mineral oil could be used in the presence of a cationic surfactant fiber conditioning agent to solubilize or liquefy a normally water-insoluble poly-lower alkylene prior to dispersing it and such dispersed poly For example, lower alkylene, such as polyethylene in the presence of the cationic surfactant fiber conditioning agent, would significantly improve the conditioning of fiber materials, particularly human hair, upon treatment with a conditioning mix in the form of an anionic surfactant-containing shampoo.

Object of the invention The object of the invention is to find new conditioning compositions for fibers, especially for hair. Explanation of the essence of the invention

The object of the invention is to find by means of a further modification of conditioning compositions those with improved conditioning effect.

This object is achieved, according to the invention, by a fiber conditioning composition comprising a cationic surfactant fiber conditioning agent, a normally water-insoluble poly-lower alkylene and a solubilizer for said poly-lower alkylene rendering it water dispersible in the presence of the cationic surfactant fiber conditioning agent and water so that the dispersed poly-lower-alkylene significantly increases the fiber-conditioning effect of the cationic fiber-conditioning surfactant. This object is also achieved by such compositions which are in the form of an anionic surfactant-containing shampoo, and by the use of such compositions and shampoos and the preparation thereof. The cationic surfactant fiber conditioning agent which is the primary conditioning agent in the fiber conditioning composition is preferably a quaternary ammonium salt, although other cationic surfactants having fiber conditioning properties may also be used at least in part. Thus, instead, imidazolinium salts and betaines and such cationic materials can be used as described in US Pat. No. 4,0000,777, as well as complexes of cationic surfactants or surfactants with anionic surfactants or surfactants and with organic acids such as citric acid. Such complexes are described in USSNs 06 / 916067.06 / 916068 and 06/916069.

The preferred quaternary ammonium salts have the formula R ¹ R ² R ³ R ⁴ N ⁺ X ^- wherein at least one R is lower alkyl and is at least one higher alkyl, the others being higher and / or lower alkyl. Preferably, R ^{1 is} lower alkyl, for example, from 1 to 4 carbon atoms, R ² and R ^{3 are} higher alkyls of 10 to 40 carbon atoms, R ^{4 is} such a lower alkyl or higher alkyl, and X is a salt-forming anion such as a halide , lower alkanosulfate or a lower carboxylic acid radical, eg. As chloride, bromide, methosulfate, ethosulfate or acetate. The lower alkyl usually has 1 to 3 or 4 carbon atoms, preferably 1 or 2 carbon atoms, more preferably methyl, and the higher alkyl

has 10 to 40 carbon atoms, preferably 12 to 18.20 or 22 carbon atoms, more preferably 14 or 16 to 18 or 22 carbon atoms, for example 16 or about 16. The anion is preferably a halogen such as chlorine, bromine or iodine, with chlorine and bromine are preferred and chlorine is particularly preferred.

The number of lower alkyls is preferably 1 or 2, the number of. higher alkyls is usually 2 or 3. It has been found desirable to have a total number of carbon atoms in the quaternary ammonium salt of at least 30, and preferably at least 34, and most preferably that the quaternary ammonium salt be 3 higher alkyls and a lower one Contains alkyl and is a chloride. The most preferred higher alkyl is cetyl, the most preferred lower alkyl is methyl, and the most preferred quaternary ammonium halide is tricetylmethylammonium chloride. Nonetheless, it is within the scope of the invention to employ other quaternary ammonium halides such as distearyldimethylammonium chloride, dilauryldimethylammonium bromide, stearylcetyldimethylammonium chloride, and other hair conditioning cationic surfactants as at least part of the fiber conditioning cationic surfactant of the compositions of this invention.

A second or secondary fiber conditioning component of the composition of the invention is normally solid water-insoluble poly-lower-alkylene. Such a polymer has a solubility of less than 1 g / 100 ml of water and often has a solubility of less than 0.1 g / 100 ml of water. In aqueous media, even when in very one-part form, it imparts little conditioning to fibrous materials such as human hair to which these aqueous compositions are applied, and it has similarly low conditioning activity from other media used for; U conditioning fiber materials are suitable. However, when applied to the compositions of the present invention in conjunction with normally liquid hydrocarbon such as mineral oil, the water-insoluble poly-lower-alkylene is activated and surprisingly enhances in conjunction with the cationic fiber-conditioning surfactant also present in the compositions of this invention the fiber conditioning effects of this cationic conditioning agent.

While various poly-lower-alkylene can be used as the secondary conditioning agent, such as polymers of hydrocarbons each of 1 to 5 carbon atoms, with molecular weights of the polymers in the range of 1,000 to 10,000 or more, a fairly useful improvement in the conditioning of the cationic conditioner, these polymers are usually those of ethylene or propylene, which may be considered straight chains of methylene groups or with varying amounts of branching and the normal molecular weights in the range of 1000 to 5000, preferably 1000 to 4000, most preferred

2,000 to 2,500 and most preferably 2,000 or 2100 or about 2,000. Oxidized versions of these polyalkylene polymers can also be used which can provide larger carboxyl-terminated hydrocarbons. These polymers, especially those which are most preferred, are dispersible in aqueous media which also contain anionic surfactants or detergents when a liquefying amount of mineral oil or other relatively low molecular weight hydrocarbons (normally in the liquid state) or equivalent, solubilizers for the Polyniedrig-alkylene is present.

The solvent precursor for the poly-lower-alkylene is one which renders it water-dispersible in the presence of the cationic surfactant-fiber-conditioning agent and water and also in the presence of anionic surfactant or detergent. The result of using the solubilizer is that the normally solid, water-insoluble polynedioalkylene is solubilized so that it can be dispersed and remain suspended in an aqueous medium without appreciable phase separation or deposition of the polymer. Also, surprisingly, the presence of the solubilizer significantly improves the fiber conditioning effect of the cationic surfactant, possibly because of the enhanced action of the secondary conditioning agent. The solubilizer is preferably a normally liquid hydrocarbon, usually having a molecular weight in the range of 150 to 1000, preferably 300 to 800, more preferably 100 to 700, and most preferably 500 to 600, for example 500 or about 550.

The hair conditioning composition may be in any suitable form and may be used in various conditioning applications. Preferably it is in liquid form, often in an aqueous medium, but it can also be used in other useful forms. Thus it may be in gel, paste, cream, foam or aerosol form, or even in solid form, and thus be dispersed when used in water or other aqueous medium. Preferred compositions of the invention are shampoos, which usually contain a surfactant such as an anionic surfactant and water. Optionally, amphoteric, ampholytic, zwitterionic and nonionic surfactants and surfactants may be used in these shampoos in place of or with the anionic surfactant (s). Various suitable such cleansing substances are listed in McCutcheon's Detergents and Emulsifiers, North American Edition, 1984. The preferred anionic surfactants also described herein may be referred to as "sulfonated" or "sulfonated." These are water-soluble lipophilic sulfates and / or sulfonates of 8 to 22 carbon atoms, preferably 10 to 18 carbon atoms, especially preferably 10 to 16 or 18 carbon atoms, and most preferably 12 to 16 or 18 carbon atoms. Among these anionic surfactants, there may be exemplified higher alkyl sulfates, paraffin sulfonates, olefin sulfonates, monoglyceride sulfates, higher fatty alcohol lower alkoxy sulfates and linear higher alkylbenzenesulfonates (Higher alkyl sulfates) are those of 12 to 16 carbon atoms and the most preferred higher alkyl lower alkoxy sulfates (sulfates of lower alkoxy substituted higher alkyl) have from 1 to 18 carbon atoms, the higher alkyl of the same being lauryl with 2 or 16 carbon atoms

3 ethoxy groups per mole. However, such alkyls may desirably have 12 to 16 carbon atoms and the alkoxy content may be 1 to 20, for example 2 to 6 ethoxy residues per mole. A most preferred higher fatty alcohol sulfate is lauryl sulfate and a particularly preferred higher fatty alcohol poly-lower alkoxy sulfate is the sulfated di or triethoxylated lauryl alcohol. Most preferably, the anionic surfactant is a mixture of higher alkyl sulfate and higher alkyl ether sulfate, each of which is present in greater proportions, and the proportion of these components is usually in the range of 10: 1 to 1:10 or 7: 1 to 1: 7 , eg 1: 5 to 5: 1. The anionic surfactants are in the form of their water-soluble

Salts which are generally salts of alkali metals (eg sodium, potassium), ammonium, amines (such as dimethylamine and trimethylamine) or lower alkanoiamines (such as triethanolamine, diethanolamine and monoethanolamine). Examples of useful surfactants are ammonium lauryl sulfate, sodium lauryl diethoxysilane, ammonium lauryl triethoxy sulfate, sodium alpha celosine sulfonate, sodium C 1 -paraffin sulfonate, sodium cocomonoglyceride sulfate, triethanolamine cetyl sulfate, and dimethylamine myristyl sulfate. However, for best results, it is preferred to use higher alkyl sulfate or a mixture of higher alkyl sulfate and higher alkyl ether sulfate such as lauryl sulfate and lauryl diethoxy or triethoxy sulfate, with the higher alkyl sulfate being present in greater amount and the ammonium or triethanolamine anion salt also being present in greater amount is.

The water used in the aqueous compositions of the invention, including the preferred shampoos, is preferably demineralized water having a hardness of less than 10 ppm as calcium carbonate, but other water may also be used if circumstances so dictate. In order to ensure that the compositions of the invention are free of microorganisms, it is preferred to use irradiated demineralized water and the various mixing vessels, tanks, tubes and containers used are kept scrupulously clean.

In addition to the requisite components for the conditioning compositions of the present invention and the shampoos which are preferred embodiments thereof, there may also be present in them various adjuvants known heretofore or found by the Applicant to impart desirable properties to the compositions of this invention. Among these excipients may be mentioned paraffins, petrolatum types, microcrystalline waxes and isoparaffins (which may all act as solubilizing hydrocarbons in addition to the mineral oil), higher fatty acid esters of lower alcohols, lower fatty acid esters of higher alcohols, and esters of higher fatty acids of higher fatty acids as filed in one concurrently filed Co-pending application (Attorney Docket No. 29520 corresponding to USSN 07 / 369,361, of which the USSN 432,644 underlying the present application is a continuation-in-part) is described as valuable for improving the hair conditioning effect of fiber treatment agents such as shampoos; Thickeners such as lower alkylcelluloses and hydroxy-lower alkylcelluloses, and gums such as xanthan gum which may also act as stabilizers; Foam modifiers and improvers such as betaines, higher fatty acid triglycerides and lower alkanolarnides, e.g. B. cocoamidopropylbetaine, triglycerides of C ₁₈ - to C _3e acids and lauric monoethanolamide; pearlescent appearance imparting substances such as ethylene glycol mono- and distearates; supplemental conditioning substances such as silicones and amino-substituted silicones as described in co-pending patent application (Appl. No. 29522 corresponding to USSN 432952) of the applicant relating to fiber conditioning compositions containing aminosilicone as a conditioning agent; anti-scale substances such as zinc pyrithione; viscosity controlling substances such as propylene glycol and sodium chloride; Protective substances and antioxidants; Antifreeze agents such as ethylene glycol; Sequestering agents such as EDTA; Substances for adjusting the pH, such as citrates and citric acid; coloring substances (dyes and dispersible pigments); and solvents such as ethanol and isopropanol. The proportions of the various components of the composition of the invention are such as to provide the desired significant increase in fiber conditioning effect. Such improvements in the fiber conditioning effects of the conditioning composition are achieved when the cationic fiber conditioning agent content is a fiber conditioning portion, the proportion of normally solid water insoluble polyethylene is sufficient to increase the fiber conditioning effect of the cationic agent when the polyethylene is in water is dispersed, and the proportion of hydrocarbon in the liquid state or mixture of hydrocarbon is such that it helps to liquefy the normally solid polyethylene and make it water-dispersible in the presence of said quaternary ammonium salt and water. For hair conditioning compositions containing anionic surfactant and for shampoos containing such anionic surfactant and water, the level of anionic surfactant is a surfactant and often a cleansing portion, depending on the intended application, and the level of water is sufficient. to form a continuous medium, if such is to be created as in the case of shampoos.

B. 12.5% ammonium lauryl sulfate and 2.5% sodium lauryldiethoxyethersulfat. The corresponding percentages for the cationic hair conditioning agent or quaternary ammonium salt are normally 0.1 to 3%, preferably 0.2 to 2%, more preferably 0.3 to 1 or 1.5%, even more preferably 0.3 to 0, 7%, and most preferably 0.4 to 0.6%, e.g. B. about 0.5%. The content of normally solid polyethylene is usually in the range of 0.1 or 0.2 to 5%, preferably 0.2 to 1.5 or 2%, more preferably 0.2 or 0.5 to 1%, and usually on most preferably at 0.3 or 0.5 to 0.9%, e.g. At about 0.4% and 0.75%.

Water content ranges are usually 50 to 95%, preferably 60 or 70 to 90%, and most preferably 65 to 80%, eg, about 73%. For non-aqueous compositions, the required components, cationic conditioner, poly-lower alkylene and mineral oil are in the same relative proportions and the aqueous medium may be omitted or replaced in whole or in part by another solvent or liquid medium such as ethanol or isopropanol become.

The ranges of amounts or proportions for the various adjuvants or other non-compulsory ingredients of the compositions of the present invention, which may be present together or in any combinations, comprise from 0.1 to 2%, preferably 0.1 to 1%, and most preferably 0.1 toO, 5%, eg about 0.25% or 0.3% isoparaffin of 10 to 18 carbon atoms, preferably 12 to 16 carbon atoms and most preferably 13 to 14 carbon atoms; 0.1 to 2%, preferably 0.1 to 1%, and more preferably 0.1 to 0.5%, e.g. About 0.35% or 0.4% paraffin of 20 to 60 carbon atoms, preferably 20 to 50 carbon atoms, and more preferably 20 to 40 carbon atoms; 0.05 to 1.5%, preferably 0.2 to 1%, and more preferably 0.4 to 0.84, e.g. B. about 0.6%

As noted above, the fiber conditioning and hair conditioning compositions of the invention may be in various physical forms, but a preferred form is liquid and a preferred mode of forming the invention is a hair conditioning shampoo. Such compositions, in order to be accepted by the marketplace, are chemically and physically stable, do not deteriorate to an unacceptable extent on storage (in particular, do not lose the good conditioning properties), and do not separate or settle or change in viscosity improperly. The shampoos according to the invention have desirable viscosities in the range from 1,000 to 15,000 Centipotse at room temperature (25 ⁰ C), preferably in the range of 3000 to 6000cp and more preferably a viscosity of about 3500 or 4000 centipoise at this temperature. The shampoos according to the invention do not settle on storage and substantially retain their improved hair conditioning properties. Also, the viscosities remain about the same as in the production, with some expected increase soon after completion of manufacture, so that the desired application viscosity of the product can be approximated.

The improved hair conditioning as compared to control samples where both the polyethylene and the mineral oil have been omitted is noticeable to the occasional consumer of the conditioning composition or shampoo and is measurable in standard tests used to improve the ease of wet combing, dry combing, handleability and to detect the retention of electrostatic charge (versus objectionable departure flight). The occasional shampoo user notes that the hair after shampooing is easier to wet and dry with the composition of the invention than a control, easier to handle, to a lesser extent electrostatically charged and to a lesser degree of undue flight. Scientific tests also show that the force required to move a comb through a standard hair sample after treating the hair with a conditioning composition according to the invention or after shampooing with a shampoo according to the invention (and rinsing) is lower than when using a control for the same purposes. Also, the flying away of the hair is less than using a control product to shampoo the hair samples. Such results have been confirmed by bodies in which various skilled artisan use the products of the invention and the control products in blind tests and determine therefrom the characteristics of combing, electrostatic charging and handleability. The compositions of the invention, including the shampoos, need not be used other than normal. Conditioners may be applied at normal temperatures in ambient temperatures or slightly elevated temperatures and allowed to vary in length on the hair, depending on the degree of conditioning desired. Normally, the conditioning agent and the hair at a temperature in the range of 15 to 50 ° C, preferably 20 to 4O ⁰ C, and the conditioning composition with the hair for 30 seconds to 10 minutes, preferably 1 to 5 minutes in contact. The amount of composition applied is normally in the range of 0.1 to 25 g, often 0.2 to 10 g, especially 0.5 to 2 g, based on the non-aqueous and non-solvent (non-alcoholic) constituents. Based on the shampoo that can be used, such rates may be in the range of 0.5 to 50 g, often 2 to 15 or 20 g and often 5 to 10 g per application. The applied composition can be brushed and / or combed through the hair and then washed out, left on the hair or partially removed, such as with a terry toweling. When the shampoo is used to wash and condition hair, it is washed out with water after it has been left on the hair as an aqueous foam for sufficient time, usually 1 to 5 minutes, to condition the hair satisfactorily , and then may be damp combed, dried, for example, by blow-drying and combed or brushed dry in the desired shape.

To prepare the compositions of the invention, including the shampoos, special measures need not be followed. However, for best stability in shampoos and aqueous products during storage and during use, it is highly desirable to have a dispersion of the water-soluble lipophilized sulfate and / or sulfonates and auxiliaries in water at an elevated temperature such as 60 or 70 to 90 ° C to form to solve the cationic conditioning agent such as a quaternary ammonium halide with the normally solid polyethylene in a liquid mineral oil at elevated temperature (70 to 9O ⁰ C) and / or to disperse and the two solutions and / or dispersions to form a stable Mixing dispersion. If adjuvants are present, those which are soluble and / or dispersible in water may be mixed with the aqueous phase materials and those which are not soluble or dispersible in the aqueous medium, such as paraffin, isoparaffin and microcrystalline wax, may but may in some cases be added to the mixture of the aqueous and lipophilic materials either before or after cooling to room temperature. Normally, perfumes are added to the other blended components after cooling to avoid losses thereof by volatilization of ingredients or degradation upon heating. If the method described is not followed, for example, if the components are mixed with one another without any distinction, unstable products may arise

The conditioning composition of Formulation A above was prepared by heating the water-soluble and water-dispersible materials of the formulation along with all or substantially all of the water of the formulation (when less than all of the water was used in this step, the remainder became the mixture the heated aqueous portion and the heated lipophilic melt or dispersion), the polyethylene, mineral oil, paraffin wax and all other "liquid" hydrocarbons heated to a temperature of about 80 ° C and the preheated mixtures with stirring for 10 minutes together, with a stable Shampoo which did not separate or settle upon storage for one month at elevated temperature, which corresponds to a storage at room temperature of at least one year The shampoo was conditioned to its conditioning properties by a panel of at least five compartments tested on the conditioning effects. The members of the panel tested hair samples and / or hair on the head shampooed with this composition, rinsed with water and dried, and evaluated the hair for various conditioning properties including ease of wet and dry combing, electrical charge, fly away, and handleability ,

Similarly, a control shampoo (B) was prepared which had the same formulation as the A shampoo and except that the polyethylene and mineral oil were omitted and replaced with water. Both compositions had pH's of about 6.5 and viscosities at 25 ° C of about 3,500 or 4,000 centipoise. Hair samples shampooed with this control composition, then rinsed and dried in the same manner as with the A composition, were evaluated by panel members. The ratings were compared to those obtained for hair shampooed, rinsed and dried with the A composition as described. The examiners found that the total conditioning effects when using the A composition were significantly better than those for the B composition. With numerical values on a scale of 1 to 5, the higher number reflecting the better conditioning, the ratings are about 2 for B treatment and about 5 for A treatment.

A shampoo of the above formulation was prepared in the same manner as described in the preparation of the shampoo of Example 1, and the melt of the lipophilic materials included polyethylene, mineral oil, paraffin wax and isoparaffin. The shampoo had a pH of about 6.5 and a viscosity of about 3500 to 4000 centipoise at 25 ⁰ C, was stable during storage, retained its initial improved hair conditioning properties, not deposed, did not separate and deteriorated not otherwise when storing up to a year.

When tested against a contrail shampoo of the same formulation in which only the polyethylene was omitted, it was measurably better in hair conditioning properties. This evaluation was based on the totality of assessments of ease of wet combing, dry combing, greater handleability, lower electrostatic charge, and less leakage of hair samples shampooed with the inventive formulation versus hair samples shampooed with the control composition.

In the above formulation, the anionic surfactants have been changed, their proportions modified, supplemental hair conditioning agents added, and it has been confirmed that the presence of the mineral oil solubilized polyethylen desirably improves the conditioning properties of the hair conditioning shampoo. The products of the invention of Examples 1 and 2 have been shown to be significant improvements over known such shampoos ^δ, mainly due to the presence of the poly-lower alkylene than be conditioned agent in conjunction with the mineral oil and the cationic conditioning surfactant. The various conditioning is not only determined by instrumental testing or trained observers, but is also apparent to the average consumer. The shampooed hair is much easier to comb wet and to brush and comb dry. It is easier to shape and manageable, at least in part because of the lower electrostatic charge generated thereon and the lower tendency of the hair to repel each other, since these repelling effects cause objectionable flying away. The compositions described in Examples 1 and 2 are hair conditioning shampoos; however, the invention is also useful for formulating fiber conditioners and hair conditioning compositions that are not shampoos. Such products can be applied to other natural fibers such as cotton, linen and wool and to synthetic fibers such as nylon, polyester, acrylic and acetate fibers to condition them. Even if one applied the required cationic conditioner, polyethylene and mineral oils of the compositions of Examples 1 <2 in solution in alcoholic or other suitable solvents or in gel or other suitable form and applied to the hair (for example by spraying, applying as Liquid and brushing, or applied as a gel and rubbed into the hair), the hair was remarkably conditioned by these applications. When these applications were from aqueous systems, better conditioning was achieved than leaving the mineral oil and any other solubilizing hydrocarbons in the compositions (in this case, the shampoos can not be prepared in a usable condition because the polyethylene does not sufficiently disperse or emulsified).

Example 3

In a modification of the formulations of Examples 1 and 2, omitting the various adjuvants from the formulations so that the shampoos produced received only the required ingredients, the anionic surfactant, the cationic surfactant conditioning agent, polyethylene, the solubilizing liquid hydrocarbon (mineral oil) and Water, the shampoos produced were less viscous than desired, but they were too

Shampooing and conditioning of the hair usable in a useful manner. By omitting the mineral oil from the formulations, the polyethylene could not be dispersed or emulsified in the system. Using other lighter and heavier mineral oils and other normally liquid hydrocarbons to solubilize the polyethylene in place of the mineral oil described improved conditioning to similar compositions without such solubilizing agents, but such other hydrocarbons may sometimes be cosmetically unacceptable or toxic.
