MXPA00008641A - High alkaline hair compositions for increased fullness and body - Google Patents

Abstract

The invention provides compositions for providing body, fullness and texture to otherwise fine or very fine keratinous fibers, particularly human hair. The compositions of the present invention have a high pH, e.g., about 8 to about 10 when the compositions contain cationic polymer, and a pH of about 8 to about 14, preferably about 8.5 to about 13, and more preferably, about 8.5 to about 10 when the compositions contain no cationic polymer. The compositions include one or more nonionic and/or cationic polymers, which, in combination with the high pH of the composition, lift the hair cuticle and allow the deposition of polymer, thus resulting in increased fullness and texture to the hair. The compositions of the present invention may be in the form of known hair care products such as, for example, shampoos, rinses and conditioners. In addition, the compositions can be formulated, for example, as lotions or creams, and the like, for consumer use. The hair care compositions of the present invention provide beneficial and long-lasting effects of body and fullness within a minute or less after application to the hair.

Description

COMPOSITIONS FOR HAIR, WITH HIGH ALKALINITY, TO INCREASE THE VOLUME AND BODY OF THE SAME.

FIELD OF THE INVENTION The present invention relates generally to hair shampoos and hair care products. More particularly, the invention relates to shampoo and hair care compositions having a high pH and comprising components which provide enhanced conditioning and body and volume (fullness) effects for the hair, particularly thin or very thin hair.

BACKGROUND OF THE INVENTION Hair care products specific to the needs of consumers with thin hair have been commercially available for a long time. Shampoos to improve the body of thin hair have been the most widely used of all hair care products. Such shampoos that are very common in the market are typically formulated to have REF. 122015 pH ranges that are from acid to neutral, for example, about 5.5 to 7.0. Many of the shampoos for low pH hair at neutral pH do not provide long-lasting volume (fullness) and body to thin and very thin hair. This may be a consequence of a failure of the prior art products to provide a perception of hair texture or to remain on the subsequent hair shaft after rinsing and shampooing. The low pH works for the closed cuticle that surrounds the hair shaft. This, in turn, decreases the penetration of active ingredients in a product and tends to decrease the diameter of the hair, resulting in a decrease in the perception of the body and volume (fullness) of the hair. U.S. Patent Nos. 4,240,450 / 4,445,521; 4,719,099 and 5,009,880 of J.-F. Grollier et al. Describe the running or clamping of anionic polymers for keratin material by means of a cationic polymer, via an interaction (ie, complexation) between the two types of polymers. The patents of Grollier et al., Do not describe or teach high pH and rapid polymer deposition. The patents describe that the substantivity of the anionic polymer is improved by its interaction with the cationic polymer. U.S. Patent No. 4,847,076 of V.M. Deshpande et al., Describes compositions and methods for improving the hair body in which agents that reduce harshness are required, for example, ammonium bisulfites, or alkali metal. The compositions described require contacting the hair for approximately 20 to 30 minutes before rinsing the hair. U.S. Patent No. 5,352,389 to G. Gazzani discloses aqueous compositions for cleaning hair, skin and scalp. The disclosed compositions include surfactants and lipases to increase their cleaning efficiency. None of the polymers are included in the compositions, which are not contemplated to improve or provide lasting body and volume (fullness). H. Edelstein, "Hair Conditioners and Conditio ing ", Cosmetics and Toiletries, Vol. 100 (4): 31-36, April 1985, describes that cationic substances that have a strong positive charge are attracted to the hair at a pH above 3.8. there is recognition that a cationic polymer in a composition at a pH of about 8 to about 10, or a nonionic polymer in a composition at a pH of about 8 to about 14, results in an increased perception of texture, body and volume ( The present invention addresses the need in the art for improved hair care products and shampoos, designed to increase volume (fullness) and body to hair, particularly thin and very thin hair. present invention provides novel formulations and alkaline compositions, which combine a higher pH, that is, from about 8 to 8.5 and above, with nonionic and / or cationic polymers, to create products that provide in a surprisingly short time a perception, of texture to the hair and impart body and Durable volume (fullness) to users with thin and very thin hair. The terms "high wpH" and "high or highly alkaline" are used interchangeably herein BRIEF DESCRIPTION OF THE INVENTION It is an object of the present invention to provide hair care products for improving and adding volume (fullness), texture and body to the keratinous fibers, particularly human hair, and more particularly, thin or very thin hair.A variety of hair care products are intended to be encompassed by the present invention, including, but not limited to, shampoos, conditioning shampoos and rinses It is another object of the present invention to provide methods and compositions for high alkalinity hair containing one or more cationic and / or nonionic polymers, for example, guars (light gray powder dispersible in water) and the like, and derivatives thereof, wherein the compositions are stable and active over time, despite the higher pH environment of the composition. According to the present invention, when the compositions contain a cationic polymer, the pH of the compositions is from about 8 to about 10.; however, when the compositions do not contain cationic polymer, the pH of the compositions may be from about 8 to about 14, preferably from about 8.5 to about 13 and more preferably from about 8.5 to about 10. Also, according to the present invention, the components of the hair compositions are rapidly deposited on the hair to provide body, volume (fullness) and texture in any way to thin or very thin hair, after shampooing and rinsing the hair. Other objects and advantages granted by the present invention will be apparent from the detailed description hereinafter.

DETAILED DESCRIPTION OF THE INVENTION The present invention provides novel compositions and formulations that are capable of imparting an obvious increase in body and volume (fullness) to the hair, particularly thin and very thin hair. As used herein, the terms composition and formulation are interchangeable. The compositions of the present invention have a pH of about 8 or greater, and comprise one or more cationic and / or non-ionic polymers, wherein the use of the products provides the user with the most complete texture and body perception to the hair. The high pH combined with one or more cationic or non-ionic polymers in the compositions of the present invention, provides the effects of volume (fullness), texture and body to the hair, together with the conditioning effects, if desired, especially if a polymer cationic such as guar, is included in the inventive compositions. While not wishing to be bound by theory, it is believed that the elevated pH of the compositions of the present invention causes the hair or an axis of a keratinous fiber to accrete and the cuticle to rise. This effect is temporary; In this way, when the hair is rinsed, the pH returns to normal or almost normal levels, and the cuticles are crushed. However, according to the present invention, the formulation of the polymers in a high pH medium, such as a shampoo, for example, allows the hair to grow and the included polymers to penetrate into the hair and deposit under the cuticle and bind to the hair. hair. The cationic and / or non-ionic polymers prevent the cuticle from completely closing, which thickened the shaft of the hair and provided it with more hardness of surface and texture, after application to the hair. This effect was unexpectedly discovered by current inventors to occur rapidly, i.e., in one minute or less. As mentioned above, by rinsing the hair and lowering the pH, the presence of the polymer deposited in the compositions of the present invention blocks the cuticle from returning to its former crushed state. According to the present invention, the polymer is trapped and the hair feels "enhanced". This imparts a thick view and feel to the hair and gives the hair fiber more body and volume (fullness). The hair care compositions of the present invention are water based and can be prepared in a variety of final formulations including lotions, creams, gels, emulsions, pumps, sprays, aerosols, mousses / foams, solutions and the like. Water is present in the compositions from about 30% to about 99%, preferably from about 50% to about 95%, most preferably from about 70% to about 90% by weight, based on the total weight of the composition . It is hereinafter to be understood that, unless otherwise specified, all reagents and components of the compositions of the present invention are present in% by weight, based on the total weight of the composition. According to the present invention, when a cationic polymer is present, the pH range of the formulations of the hair care product and the shampoo of the present invention is from about 8 to about 10; in the absence of a cationic polymer in the formulations, the pH range can be from about 8 to about 14, preferably from about 8.5 to about 13, and most preferably, from about 8.5 to about 10. The nonionic polymers and Cationics suitable for use in the compositions of the invention provide the benefits of penetrating and thickening the hair, thereby preventing the sinking of the cuticles during rinsing and allowing deposition of the polymer on the hair surface to increase the texture. further, in the high pH environment of the compositions of the present invention, these polymers deposit and produce their beneficial effects in a matter of seconds, thus providing the compositions of the present invention, advantages in time and efficiency. Cationic polymers which may be used in the present invention include, but are not limited to, polymers having quaternary amino groups. More specifically, a cationic polymer for use in the present invention is a cationic guar gum derivative or locust bean gum.

Such gums are polygalactomannases containing two units of mannose with a glycoside bond and a galactose unit attached to one of the hydroxyl groups of the mannose units. The hydroxyl groups are reacted with certain reactive quaternary ammonium compounds to obtain the cationic derivative. Suitable quaternary ammonium compounds for preparing the cationic gum derivatives of the present invention have the following structure: wherein Ri, R2 and R3 are substituted alkyl, aryl and alkyl and aryl groups, R4 is selected from the group consisting of epoxyalkyl and halohydrin, and Z is an anion, for example Cl ", Br", I "and HS04". Suitable epoxyalkyl groups have the structure: H2C-CH-Rs O and the appropriate halohydrins have the structure wherein R5 is a divalent alkylene of 1 to 3 carbons and X is a halogen. Particularly preferred is the guar 3- (trimethylamino) -2-hydroxypropyl chloride compound which has the structure: R-O-CHs-CH-CHa- * (CH3) 3C1"OH wherein R is a polygalactomannase molecule based on guar, and is sold as Cosmedia Guar 216N by Henkel Corporation. Another preferred cationic guar is a quaternary ammonium derivative of guar hydroxypropyl, such as guar hydroxypropyltrimonium chloride, which is exemplified by the JAGUAR0 products commercially available from Rhone-Poulenc. Nonionic polymers which are suitable for use in the present invention are generally classified as water soluble non-ionic poly (oxide * ethylene *) homopolymers (e.g. polyethylene glycols) having the following structure: H (OCH2CH2) nOH, where n = 2,000 to 115,000. More specifically, the nonionic polymers include the Polyox® water soluble resins (Amerchol) which are completely water soluble, are stable at pH from about 8 to 12 and vary in molecular weight from about 100,000 to about 5 x 106. Examples non-limiting of particular grades of polyethylene glycol water-soluble resins (Polyox) suitable for use in the present invention are included in the following Table 1: TABLE 1 Polyox WSR N-750 (PEG-7M) is preferred The polymers are present in the compositions according to the present invention in an amount effective to increase body and volume (fullness) of the hair. More specifically, the polymers are present at from about 0.01% to about 10%, preferably, from about 0.05% to about 5% and most preferably, from about 0.1% to about 1%. In another embodiment of the present invention, one or more surfactants are. they include in high pH compositions as described. Suitable surfactants are described in the following. The preferred surfactants in these compositions are anionic and / or amphoteric surfactants, and betaines. Non-limiting examples of the preferred surfactants include sodium lauryl sulfate, cocamidopropyl betaine (CAPB), sodium laureth sulfate and combinations or mixtures thereof. A preferred composition of the present invention comprises a high pH, for example, from about 8.0 to about 10, at least one cationic polymer and / or a nonionic polymer and one or more anionic surfactants. Preferred polymers in the compositions of the present invention include, but are not limited to, Jaguar® (Rhone-Poulenc), Polyox® (Amerchol), Celquats (National Starch), Merquats (Merck), Gafquats (ISP), Polymer JR (Amerchol) and Cosmedia Polymer LR (Henkel Corporation). Suitable anionic surfactants for use in the compositions of the present invention are those generally incorporated into hair care products of the desired types. Generally for shampoos, the anionic surfactants are water-soluble alkyl or alkylaryl sulfates or sulfonates, having from about 8 to about 22 carbons, preferably from about 12 to about 18 carbons in the alkyl radical, which may be straight or branched chain . These surfactants also include such classes of compounds that are ethoxylated with from 1 to 5 moles, preferably 1 to 3 moles of ethylene oxide (EO) per molecule. The sulfonate or sulfate group is typically neutralized base to provide an alkali metal, especially sodium, potassium, ammonium, or mono-, di-, or triethanolamine.

Exemplary anionic surfactants of the aforementioned classes include, but are not limited to: sodium cetyl sulfate; sodium myristyl sulfate; sodium lauryl sulfate; sodium sebosulfate; sodium decyl sulfate; sodium decylbenzenesulfate; sodium tridecylbenzenesulfonate; Sodium olefin sulphonate of C14-C? 6; C 2 -C 5 sodium alcohol sulfate; Sodium lauryl ether sulfate; sodium myristyl ether sulfate; Sodium lauryl ether sulfate polyoxyethylene (5 moles EO); Sodium lauryl ether-polyoxyethylene (12 moles EO); sodium nonylphenyl ether sulfate; sodium polyoxyethylene (1 to 4 moles EO); Ci2_C? 5 alkyl ether sulfate and sodium lauryl sulfoacetate. Although the sodium salts are identified above, the other cations previously named will also be suitable, especially ammonium. Other suitable anionic surfactants include sulfosuccinates, for example, sodium dioctylsulfo succinate; disodium lauryl sulfosuccinate and the middle ester of disodium lauryl-polyoxyethylene alcohol (1 to 4 moles EO) of sulfosuccinic acid; mono sulfated glycerides, for example, sodium cocomonoglyceride sulfate; sarcosinates, for example, sodium cocoyl sarcosinate and sodium lauroyl sarcosinate; esters of isethionic acid, for example, sodium cocoyl sethionate and sodium lauroyl isethionate; taurátos, for example, N-metil-N-cocoil taurato of sodium and N-metil-N-oleoiltaurato of sodium. The soaps may also be incorporated, for example, sodium stearate, sodium laurate and sodium isethionate. Also suitable are the derivatives of lisalbínico and protalbínico acid, generally classified as Maypon surfactants. The anionic surfactants can be used simply or in combination. Frequently, two or more anionic surfactants can be mixed to achieve a desired viscosity, beneficial cleansing or other properties. Anionic surfactants are typically present in the compositions of the present invention in an amount of about 1% to about 50% active. However, the concentration is certainly not critical as much as the concentration employed does not interfere with the physical stability of the product shampoo. Preferably, the anionic surfactants are present in an amount from about 5% to about 35% active, more preferably, from about 10% to about 25% active. Preferred anionic surfactants are sodium or ammonium sulfates of C12 to Ci4, and sodium or ammonium alkylethylsulfates of C? 2 to C? 4 having from 1 to 3 moles EO. An especially preferred anionic surfactant system (eg, a surfactant mixture) comprises from about 4% to about 15% of active sodium lauryl sulfate and from about 3% to about 10% of active sodium lauryl ether sulfate. Other types of surfactants can also be used in conjunction with the anionic surfactants in the compositions of the present invention. Such surfactants include nonionic surfactants, betaines (a class of zwitterionic surfactants), amphoteric and cationic. Suitable nonionics can be broadly defined as compounds produced by the condensation of alkylene oxide groups (hydrophilic in nature) with an organic hydrophobic compound, which can be aliphatic or alkyl aromatic in nature. Non-ionics are characterized by long chain units of oxyethylene or oxyethylene-oxypropylene. Illustrative materials are the polyoxyethylene octyl and nonylphenyl ethers having above about 6 moles of ethylene oxide, preferably about 6 to 15 moles of ethylene oxide, for example, the Igepál surfactants; ethylene-propylene oxide block copolymers generally designated as Pluronic® surfactants, and polyoxyethylene sorbitan monostearates and monolaurates, generally designated as Tween surfactants. However, these classes of nonionic surfactants are exemplary and should not be considered as limiting. The nonionic surfactant is generally present in the compositions of the present invention in an amount from about 0.1% to about 10%, preferably from about 0.1% to about 5%. Betaines, a class of zwitterionic surfactants, are also suitable for use in the present invention. Examples of betaines which are useful in the foregoing include the higher alkyl betaines such as cocodimethyl carmethyl betaine, lauryldimethyl carmethyl betaine, lauryldimethyl alpha-carethyl betaine, cetyldimethyl carmethyl betaine, lauryl bis- (2-hydroxyethyl) carmethyl betaine , bis- (2-hydroxypropyl) carmethyl betaine of stearyl, gamma-carpropyl betaine of oleyl-dimethyl, bis (2-hydroxypropyl) alpha-carethyl betaine of lauryl, and the like. The sulfobetaines are illustrated by cocodimethylsulfopropyl betaine, dimethylsulfopropyl betaine stearyl, dimethylsulfoethyl betaine lauryl, bis- (2-hydroxyethyl) sulfopropyl betaine lauryl, and the like. Amido betaines and amidosulfo betaines, especially those in which the radical RCONH (CH2) 3 is bonded to the nitrogen atom of betaine, are useful in the present invention, for example, cocoamidopropyl betaine. Illustrative amphoteric surfactants that can be used in the compositions of the present invention are those that can be broadly defined as derivatives of secondary and tertiary aliphatic amines in which the aliphatic radical can be straight chain or branched chain, wherein one of the substituents aliphatic contains from about 8 to about 18 carbon atoms and one contains an anionic water solubilizing group, for example, car, sulfonate, sulfate, phosphate or phosphonate. Examples of particularly useful amphoteric surfactants include sodium 3-dodecyl aminopropansulfonate, sodium 3-dodecylaminopropionate, disodium cocoanfodipropionate, disodium cocoamphodiacetate, N-alkyl taurines, N-alkyl-β-imino dipropionates and basic ammonium compounds derived from imidazoline substituted with 2-alkyl, for example Miranol surfactants, as described in U.S. Patent No. 2,528,378. The amphoteric surfactants listed above are not intended to be limiting. The compositions of the present invention may also contain additive ingredients that improve, for example, the quality and elegance of the final products, as set forth in the following. These additional components are present at levels that are effective to provide their intended functions. Foam binders or foam stabilizers are materials that increase the quality, volume and stability of the foam. They also improve the viscosity. Preferred foam binders are fatty acid alkanolamides, such as lauryl ethanolamide, lauryl monoethanolamide and cocomono-ethanolamide. Other foam binders are "super" amides, for example, super amide B-5, fatty alcohols, sarcosinates, phosphates and dodecylbenzenesulfonates. Foam binders are typically present in an amount from about 0.1% to 10%, preferably from about 0.5 to about 5%. Opacifying agents are used, for example, in cream compositions. Suitable opacifying agents are higher alcohols, such as stearyl and cetyl alcohol, and higher acids, such as behenic acid. The mono- and di-es glycol tearates are also effective opacifiers. Also suitable are the alkaline earth metal fatty acid soaps, such as calcium stearate and magnesium stearate. Magnesium silicates are also useful for this purpose. Opacifying agents are typically present in an amount from about 0.1% to about 10%, preferably, from about 0.5% to about 5%. Viscosity control agents are frequently useful for stably regulating the viscosity of the ingredients of a shampoo composition. Suitable viscosity control agents are lower alcohols, for example, isopropyl glycol and butyl alcohol; and lower glycols, for example diethylene glycol, terpineol and diethylcarbonate tol. These agents are typically present in an amount from about 0.1% to about 5%, preferably, from about 0.5% to about 2.5%. Sequestering agents are useful to prevent the formation of lime soap film when washing with shampoo the hair is rinsed with hard water. Suitable materials are ethylenediaminetetraacetic acid (EDTA), citric acid, sodium xylene sulfonate and sodium naphthalenesulfonate. Sequestering agents are typically present in an amount from about 0.01% to about 5%, preferably from about 0.1% to about 1%. Thickening agents increase the viscosity of a shampoo product. Suitable materials are natural gums such as tragacanth, xanthan, acacia and carob; and synthetic gums such as hydroxypropylcellulose and methylcellulose. Polyvinyl alcohols can also be used. The alkanolamides (e.g. cocamide MEA and lauramide DEA) can also be used "super" amides and the glycol or glycerol stearates. The thickening agents are present in an amount to provide the desired viscosity, typically from about 0.1% to about 10%, preferably, from about 0.1% to about 10%. Preservatives are typically present to prevent degradation of bacterial and mold action. Preferred are formaldehyde, methyl, ethyl, propyl and butyl hydroxybenzoates, dimethyldimethylhydantoin, methylchloroisothiazolinone, methylisothiazolinone, 2-phenoxyethanol and mixtures thereof. They are present in compositions of an amount from about 0.01 to about 1%. Cationic surfactants may also be employed in conjunction with the other ingredients, for example, to add conditioning properties to the compositions of the present invention. Non-limiting examples of such cationic surfactants are represented by ricinoleamidopropyl ethyldimonium ethosulfate; quaternium 75, isotearamido-propyl ethyldimonium ethosulfate and linoleamidopropylor PG-dimonium chlorophosphate. Such cationic surfactants are generally present in the compositions in an amount to perform their intended functions, i.e. from about 0.1% to about 5%. The amount of water used in the formulation of the compositions of the present invention is generally the amount necessary for the sufficient quantity (QS) at 100%. However, it will be appreciated by those skilled in the art that in formulating the compositions described, the amount of water may require adjustments when necessary to ensure that the final composition is stable in the sense that it is a homogeneous solution.

Other additives include antioxidants, such as sodium sulfite; propellants; suspension agents; fragrances and herbal; coloring agents; protectors against the sun; and buffering or pH control agents, such as citric acid, each of which is present in an amount, usually less than about 5%, effective to provide its intended function. An anti-dandruff component, for example, selenium sulfide, can also be included at an effective level.

EXAMPLES The following examples are intended to illustrate and exemplify the various aspects for carrying out the present invention and are not intended to limit the invention. The compositions prepared as shampoos according to the present invention were compared with other shampoo formulations having acidic pH (for example, a pH between about 5.0 and 6.0) and alkaline pH (for example, a pH between about 8.5 and 9.5) in studies of use in the consumer's home. Table 2 shows the results of the consumer use studies in which the shampoo formulations were tested as set forth in Examples 1-6 hereinafter. For the consumer use studies presented in Table 2, all the test samples were placed in coded plastic bottles and labeled "thin hair shampoo" with simple instructions for use. Users in the home use study had self-perceived thin / very thin hair. They used the products as indicated for two weeks and then responded to a return questionnaire. It is understood that the term "body" as it is evaluated in studies of consumer use includes both visual and tactile impressions or perceptions attributed to the hair by the user. Those skilled in the art will appreciate that an increase in the "body" of the hair indicates to the user the impression or general perception of a sensation of thickness or fullness, and / or manageability, and / or an appearance of thickness or fullness in the hair. With reference to the consumer use test data of Table 2, Examples 1-3 are shampoo formulations with low pH (acid) commercially available for thin hair.

They differ slightly in pH (due to the normal pH variation from batch to batch). The formulation of Example 1 does not contain polymer; the formulation of Example 2 contains a cationic polymer; and the formulation of Example 3 contains a nonionic polymer. The consumer usage test data shows that none of the actual differences in bodywork action were perceived between the acid formulations of Example 1 that did not contain polymer and the acid formulation of Example 3 containing a nonionic polymer. In addition, a decrease in the general opinion of the user was observed when the acid formulation without polymer was compared with the formulation with cationic polymer (ie, 50% against 40%, respectively). Examples 4-6 are representative of shampoos with a high pH (alkaline) for thin hair of the present invention. The formulation of Example 5 contains a cationic polymer; the formulation of Example 6 contains a nonionic polymer, while the formulation of Example 4 contains no polymer. Example 4 was included to demonstrate the surprising results obtained when the cationic polymer was added to the formulation with high pH. ***** insert table ***** One skilled in the art observing the data in relation to Examples 1, 3 and 4 in Table 2 would expect that increasing the pH from an acid pH to an alkaline pH, with or without polymer, would have no effect of giving real body on the thin hair In fact, this is observed when the data obtained from the use of Examples 1, 3 and 4 are compared. Also, adding a cationic polymer to the acid shampoo formulation resulted in a decrease in body action when pre-warned by users (compare Example 2 versus Example 1). However, the inclusion of a cationic polymer in the alkaline pH formulation, as represented by the formulation of Example 5, surprisingly and unexpectedly produced a product having favorable attributes in 69% of the test population ("general opinion") , and a particularly high evaluation for the action of giving body (ie, "perfect body" - 81%; "total body" -56%). In virtually all of the categories in Table 2, the alkaline formulation containing cationic polymer surprisingly surpasses all other test formulations in gaining a favorable opinion of the perception of body enhancement by users. These results are particularly surprising and unexpected since, prior to the present invention, a cationic polymer at alkaline pH was not known to possess any body-building ability. The inclusion of a non-ionic polymer in the alkaline shampoo formulation (Example 6) demonstrated a tendency towards an improvement in the body-forming action and an increase in favorable attributes for the users, compared with the alkaline formulation without polymer and with the formulations acids. In summary, the data in Table 2 reveal that the pH had no real effect on the increased body perception in the formulations without polymer. The cationic polymer in a formulation at acid pH resulted in a general deterioration in increased body perception. Surprisingly, the alkaline pH formulation containing a cationic polymer resulted in a product with a profound increase in body perception by the user. Until the present invention it was not recognized or appreciated that a cationic polymer in an alkaline formulation was stable and caused an increase in the action of giving body to the hair.

The acidic and alkaline formulations presented in Examples 1-6 contain a mixture of anionic / amphoteric surfactant which is generally used in compositions of this type. In these formulations, the surfactant mixture used was the same, although the amount of surfactant was varied in such a way that the final product was stable in any environment of the acidic or alkaline pH of the product. It will be appreciated by those who are experienced in the art that the stability of a product is a key criterion to achieve prior to the beginning of testing the use by the consumer. Through stability, the aim is to maintain a homogeneous solution. More specifically in this regard, nonionic polymers are not tolerant for high levels of surfactant due to their competition without water with ethoxylated surfactant. In this way, the use of lower levels of surfactant was necessary to achieve a stable product. Cationic polymers, on the other hand, can tolerate higher levels of surfactant in some formulations (eg, acid), but not in others (eg, alkaline).

EXAMPLES 1-3 Acidic pH Formulations The pH of the acidic shampoo formulations presented in Examples 1-3 (and as tested in Table 2) was between 5.0 and 6.0, which is typical of formulations of this type. Variation was expected in a batch-to-batch basis both above and below the expected pH range. The pH of the acid / non-polymer formulation of Example 1 was a little lower than the typical range because it was a production batch that had aged; thus, a slight downward trend in pH was both expected and acceptable based on the stability data.
