Description

  The present invention relates to personal care compositions containing a cationic cellulose polymer and an anionic surfactant system. More specifically, the present invention relates to an anionic surfactant system having a specific ratio of ethoxylate to sulfate such that when combined with a cationic cellulose polymer, the maximum degree of coacervate is achieved in use. It relates to a personal care composition containing.

  Personal care compositions containing various combinations of detersive surfactants and conditioning agents are known. These products typically include an anionic detersive surfactant combined with a conditioning agent such as silicone, hydrocarbon oil, fatty acid ester, or combinations thereof. These products have become more popular among consumers as a means to conveniently obtain all hair and skin conditioning and cleaning performance from a single personal care product.

  However, many personal care compositions do not provide sufficient adhesion of the conditioning agent on the hair and skin during the cleaning process. In the absence of such adhesion, the majority of the conditioning agent is washed away during the cleaning process, thus providing little or no conditioning benefit. In the absence of sufficient deposition of the conditioning agent on the hair and skin, a relatively high concentration of the conditioning agent may be required in the personal cleaning composition to provide adequate conditioning performance. However, high concentrations of conditioning agents can increase raw material costs, reduce foaming, and present concerns about product stability.

  Obtaining good adhesion of the conditioning agent is further complicated by the action of the detersive surfactant in the personal care composition. Detersive surfactants are designed to remove or remove oils, fats, dirt, and particulate matter from the hair and skin. In doing so, the detersive surfactant may also interfere with the deposition of the conditioning agent and may remove both the deposited and unattached conditioning agent during the rinse. This further reduces the deposition of the conditioning agent on the hair and skin after rinsing, thus further reducing the conditioning performance.

  One known method for improving the deposition of conditioning agents involves the use of specific cationic deposition polymers. These polymers may be synthetic or natural cellulose, or guar polymers modified with cationic substituents. The cationic charge density of such polymers, especially when used in personal care compositions, is minimized to avoid incompatibilities with anionic materials in the product, such as anionic surfactants. Thus, most personal care compositions containing both an anionic detersive surfactant and a cationic deposition polymer have a relatively low concentration of coacervate conditioning. There is still a need for improved conditioning performance in personal care compositions.

The present invention is directed to personal care compositions comprising:
a. From about 0.01 to about 5% by weight of a cationic cellulose polymer, wherein the cationic cellulose polymer has a molecular weight of at least 800,000;
b. About 5 to about 50% by weight of an anionic surfactant system having an ethoxylate concentration and a sulfate concentration comprising:
i. In this case, the ethoxylate concentration is 1.04 multiplied by the molecular weight of the cationic cellulose polymer, and divided by 1,000,000 plus about 0.75 to about 3.25,
ii. An anionic surfactant system wherein the sulfate concentration is 0.42 multiplied by the charge density of the cationic cellulose polymer plus about 1.1 to about 3.6;
c. From about 0.01 to about 5% by weight of a monovalent or divalent salt; and d. At least about 20% by weight of an aqueous carrier.

Alternatively, the present invention comprises a personal care composition having a transmittance of not less than 70% at 600 nm, or a cationic cellulose polymer having a molecular weight of at least 500,000, and further having a particle size of 80 nm or less. A personal care composition comprising about 10% by weight of microemulsified oil is intended.
The present invention is further directed to methods of using personal care compositions.

  The foregoing and other features, aspects, and advantages of the present invention will become apparent to those of ordinary skill in the art upon reading this disclosure.

While the specification concludes with claims that particularly point out and distinctly claim the invention, it is believed the present invention will be better understood from the following description.
The personal care composition of the present invention includes a cationic cellulose polymer, an anionic surfactant system, a salt, and water. Each of these essential components, as well as preferred or optional components, are described in detail below.

  All percentages, parts, and ratios are based on the total weight of the composition of the present invention, unless otherwise specified. All such weights are based on the active substance concentration as far as the ingredients described are concerned, and thus do not include solvents or by-products that may be included in commercially available materials, unless otherwise specified. The term “weight percentage” may be referred to herein as “wt%”.

  Unless otherwise specified, all molecular weights used herein are weight average molecular weights expressed as g / mol.

  As used herein, the term “charge density” refers to the ratio of the number of positive charges in the monomer units that make up the polymer to the molecular weight of the monomer units. The charge density multiplied by the polymer molecular weight determines the number of positively charged sites in a given polymer chain.

  As used herein, “comprising” means that other steps and other components that do not affect the final result can be added. This term encompasses the terms “consisting of” and “consisting essentially of”. The compositions and methods / processes of the present invention may be any additional or optional components, components, steps, or steps described herein, as well as essential elements and limitations of the invention described herein. It may also consist of, consist of, and consist essentially of, restrictions.

  As used herein, the term “polymer” includes materials made by the polymerization of one type of monomer or made by two (ie, copolymers) or more monomers.

  As used herein, the term “solid particles” means particles that are not liquid or gas.

  As used herein, the term “water soluble” means that the polymer is soluble in water in the composition of the present invention. In general, the polymer should be soluble at 25 ° C. at a concentration of 0.1%, preferably 1%, more preferably 5%, and most preferably 15% by weight of the water solvent.

  As used herein, the term “water insoluble” means that the polymer is not soluble in water in the composition of the present invention. The polymer is therefore immiscible with water.

  The transparency of the composition is measured using ultraviolet / visible (UV / VIS) spectrophotometry, which measures the absorption or transmission of ultraviolet / visible light by a sample. A light wavelength of 600 nm has been shown to be suitable for characterizing the transparency of cosmetic compositions. Typically it is best to follow specific instructions relating to the specific spectrophotometer used. In general, the procedure for measuring transmittance starts by setting the spectrophotometer to 600 nm. Next, a calibration “blank” is performed to calibrate the measured value to 100% transmittance. The test sample is then placed in a cuvette designed to fit a particular spectrophotomer and the transmittance is measured by the spectrophotomer at 600 nm.

  All cited references are incorporated herein by reference in their entirety. Citation of any reference is not an admission regarding determination of utility as prior art to the claimed invention.

  Although both surfactant composition and polymer properties are known to affect the effectiveness of conditioning, known techniques focus on polymer properties and for specific surfactant compositions Does not teach anything. Moreover, this technique generally teaches away from a particular surfactant composition and generally describes a wide range of suitable surfactants from which the composition may be selected.

  One embodiment of the invention is a composition that combines certain specific concentrations and ratios of surfactants, as represented by the overall sulfate and ethoxylation values (described herein). Relates to the surprising discovery of maximizing conditioning benefits by maximizing coacervate formation. Moreover, although the optimal surfactant mix is different for each polymer, the authors have found that the optimal surfactant composition can be represented by two parameters. These parameters include sulfate and ethoxylation values, which maximize coacervate formation when expressed as a function of polymer charge density and molecular weight.

  Without being bound by any particular theory, coacervates provide improved hair and skin conditioning without any additional conditioning actives. Further, when dispersed conditioning agent droplets are added to the substrate, the coacervate provides an improved mechanism for conditioning agent deposition, resulting in conditioning agent deposition, which provides further conditioning benefits.

The average molecular weight of such suitable cationic cellulose polymers is generally about 500,000 to 10,000,000, preferably about 800,000 to about 5,000,000, even more preferably 1,000,000 to 2, 500,000. Suitable cationic cellulose polymers have a cationic charge density of at least about 0.5 meq / g at the pH for which the personal care composition is intended for use, and this pH is generally from about pH 3 to about pH 9, preferably about pH about It is in the range of 4 to about pH 8. “Cationic charge density” of a polymer, as that term is used herein, refers to the ratio of the number of positive charges in the monomer units that the polymer comprises to the molecular weight of the monomer units.

  The concentration of the cationic polymer in the personal care composition ranges from about 0.01% to about 5.0%, preferably from about 0.05% to about 3.0% by weight of the personal care composition. is there.

  Suitable cationic cellulose polymers include those according to the following formula I:

式中、Ａは、セルロースアンヒドログルコース残基のようなアンヒドログルコース残基であり；Ｒは、アルキレンオキシアルキレン、ポリオキシアルキレン、又はヒドロキシアルキレン基、又はこれらの組み合わせであり；Ｒ¹、Ｒ²、及びＲ³は独立して、アルキル、アリール、アルキルアリール、アリールアルキル、アルコキシアルキル、又はアルコキシアリール基であり、各基は約１８個までの炭素原子を含有し、各カチオン性部分の炭素原子の総数（即ち、Ｒ¹、Ｒ²及びＲ³にある炭素原子の合計）は、好ましくは約２０以下であり；及びＸはアニオン性対イオンである。ポリマーが、水中、パーソナルケア組成物中、又はパーソナルケア組成物のコアセルベート相中で可溶性のままである限り、並びに対イオンがパーソナルケア組成物の必須構成成分と物理的及び化学的に適合性があるか、又はさもなければ製品性能、安定性若しくは審美性を過度に損なわない限り、本発明のカチオン性ポリマーとの関連において、いずれのアニオン性対イオンも用いることができる。そのような対イオンの非限定例には、ハライド（例えば、塩素、フッ素、臭素、ヨウ素）、サルフェート及びメチルサルフェートが挙げられる。これらの多糖類ポリマー中のカチオン性の置換の程度は、典型的には、アンヒドログルコース単位当たり約０．０１〜１のカチオン性基である。

Where A is an anhydroglucose residue such as a cellulose anhydroglucose residue; R is an alkyleneoxyalkylene, polyoxyalkylene, or hydroxyalkylene group, or combinations thereof; R ¹ , R ² and R ³ are independently alkyl, aryl, alkylaryl, arylalkyl, alkoxyalkyl, or alkoxyaryl groups, each group containing up to about 18 carbon atoms, the carbon of each cationic moiety The total number of atoms (ie, the sum of carbon atoms in R ¹ , R ² and R ³ ) is preferably about 20 or less; and X is an anionic counterion. As long as the polymer remains soluble in water, in the personal care composition, or in the coacervate phase of the personal care composition, and the counter ion is physically and chemically compatible with the essential components of the personal care composition. Any anionic counterion can be used in the context of the cationic polymer of the present invention, as long as it does not otherwise or unduly impair product performance, stability or aesthetics. Non-limiting examples of such counterions include halides (eg, chlorine, fluorine, bromine, iodine), sulfate and methyl sulfate. The degree of cationic substitution in these polysaccharide polymers is typically about 0.01 to 1 cationic groups per anhydroglucose unit.

  A preferred cationic cellulose polymer is a salt of hydroxyethyl cellulose reacted with a trimethylammonium substituted epoxide, referred to in the art (CTFA) as polyquaternium 10 and available from Amerchol Corp. (Edison, NJ, USA) It is.

  The cationic cellulose polymer herein is soluble in the personal care composition or in the personal care composition formed by the cationic cellulose polymer and the anionic surfactant component described herein. It is soluble in the complex coacervate phase. Cationic cellulose polymer composite coacervates can also be formed with other charged materials in personal care compositions.

  The formation of coacervate includes molecular weight, component concentration, ratio of interacting ionic components, ionic strength (including, for example, adjustment of ionic strength by addition of salt), charge density of cationic and anionic components, It depends on various criteria such as pH, as well as temperature. The effects of coacervate systems and these parameters are described, for example, in J. J. Caelles et al., “Anionic and Cationic Compounds in Mixed Systems,” Cosmetics & Toiletries, 106, April 1991, pp. 49-54. , C.I. J. et al. CJvan Oss, “Coacervation, Complex-Coacervation and Flocculation”, J. Dispersion Science and Technology, Volume 9 (5 6), 1988-89, pages 561-573, and D.C. J. et al. DJ Burgess' “Practical Analysis of Complex Coacervate Systems”, J. of Colloid and Interface Science, Vol. 140, No. 1, November 1990, Pp. 227-238, the descriptions of which are incorporated herein by reference.

  It is particularly advantageous that the cationic cellulose polymer is present in the coacervate phase in the personal care composition, or that the coacervate phase is formed when the personal care composition is applied to or washed away from the hair. It is considered to be. Complex coacervates are believed to deposit on the hair more quickly. Accordingly, it is generally preferred that the cationic cellulose polymer be present as a coacervate phase in the personal care composition or form a coacervate phase upon dilution.

  Techniques for analyzing the formation of complex coacervates are known in the art. For example, at any stage of dilution, microscopic analysis of the personal care composition can be used to determine whether a coacervate phase has been formed. Such a coacervate phase can be identified as an additional emulsified phase in the composition. The use of a dye can help to distinguish the coacervate phase from other insoluble phases dispersed in the personal care composition. In clear compositions, a spectrophotomer can also help determine at which dilution ratio (or dilution ratios) of water and personal care composition the coacervate is most widespread. it can. For example, a measured transmittance value of the dilution of less than 85% indicates significant coacervate formation. As the measured permeability value of the dilution decreases, typically a higher concentration of coacervate is formed.

  Separating the diluted personal care composition with a centrifuge and measuring the coacervate gravimetrically is an alternative quantitative technique applicable to opaque or transparent compositions, and especially when analyzing opaque products Convenient to. As used herein, several different dilutions are made in 50 mL centrifuge tubes and centrifuged using a Beckman Couller TJ25 centrifuge at 963 rad / s (9200 rpm) for 20 minutes. It was. The supernatant was then removed and the remaining stable coacervate was evaluated gravimetrically. A blank (polymerless shampoo) is run to establish a baseline. Values are calculated for each dilution and the peak amount reported from this method is referred to herein as by coacervate centrifugation.

B. (Anionic surfactant system-ethoxylate and sulfate)
The personal care composition of the present invention includes an anionic surfactant. A surfactant component is included to provide cleaning performance to the composition. The surfactant components then include ethoxylated surfactants and sulfates, and optionally zwitterionic or amphoteric surfactants, additional surfactants, or combinations thereof. Such surfactants should be physically and chemically compatible with the essential components described herein or otherwise unduly compromise product stability, aesthetics or performance. Should be.

  Suitable anionic surfactant components for use in the personal care compositions herein include those known for use in hair care or other personal care compositions. The concentration of the anionic surfactant component in the personal care composition should be sufficient to provide the desired cleaning and foaming performance, and generally from about 5% to about 50% by weight of the composition. %, Preferably about 8% to about 30% by weight, more preferably about 10% to about 25% by weight.

Optimizing surfactant concentration and type to maximize the potential performance of polymer systems when considering coacervate generation performance characteristics, wet conditioning performance, dry conditioning performance, and deposition of conditioning components on hair The present inventor has found that it is necessary to make it. Systems with ethoxylated and non-ethoxylated surfactants having a ratio of ethoxylated and non-ethoxylated surfactants greater than 2: 1 have favorable performance, in which case the ethoxylated interface The inventors have discovered that the activator has an ethoxylation greater than 2 moles. The inventors have further discovered that it is necessary to optimize ethoxylate and sulfate concentrations to maximize the potential performance of the polymer system. To do this, the aforementioned performance characteristics were plotted on the graph against the ethoxylate concentration and against the sulfate concentration. Sulfate and ethoxylate “peaks” or optimal concentrations were then plotted on a graph against various chemical descriptors of cationic polymer structures including molecular weight and charge density. When plotting on the graph the optimal concentration of ethoxylate providing peak performance with the “y” axis and the molecular weight of the polymer as the “x” axis divided by 1,000,000, R ² > 0 The inventors have discovered that there is a clear correlation with respect to. The line equation indicated that the slope of the line was approximately equal to 1.04 and that the intercept was between about 0.75 and about 3.25. Preferably, the intercept is greater than 0.75, more preferably greater than 1.25, and more preferably greater than 1.75. Preferably, the section is less than 3.25, more preferably less than 2.75, and more preferably less than 2.25. Thus, for any given molecular weight cationic cellulose polymer, the optimum ethoxylate concentration can be calculated. A second correlation was also found, in which case the optimal concentration of sulfate was plotted on the graph as the “y” axis and the charge density was plotted on the graph as the “x” axis. Again, a relatively straight line was recognized, in which case the slope of the line was equal to approximately 0.42, and the intercept fell between about 1.1 and about 3.6. Preferably, the intercept is greater than 1.1, more preferably greater than 1.6, and more preferably greater than 2.1. Preferably, the intercept is less than 3.6, more preferably less than 3.1, and more preferably less than 2.6. This discovery is surprising and explains how to maximize the performance of various polymers, especially those having a molecular weight in the range of 500,000 to 2,000,000.

Thus, the percentage of ethoxylate can be calculated based on the specific molecular weight of the surfactant with known moles of ethoxylation based on the stoichiometric nature of the surfactant structure. Similarly, the sulfate percentage can be calculated based on the specific molecular weight of the surfactant and the completion of the sulfation reaction. Analytical techniques have been developed to measure the percentage of ethoxylation or the percentage of sulfate in a surfactant system. The concentration of ethoxylates and sulfates that are representative within a particular surfactant system is calculated from the percentage of ethoxylation of each individual surfactant and the percentage of sulfate in the following manner:
Concentration of ethoxylate in the composition = percentage of ethoxylation X percentage of active ethoxylated surfactant.

  Sulfate concentration in the composition = percentage of sulfate in ethoxylated surfactant x percentage of active ethoxylated surfactant + percentage of sulfate in non-ethoxylated surfactant x active non-ethoxylated surfactant percentage.

Sample calculation:
Example 1 shows an ethoxylated surfactant containing a non-ethoxylated surfactant having an ethoxylate concentration of 0.294321% and a sulfate concentration of 0.188307%, and a sulfate percentage of 0.266845. Both surfactants are 29% active.

  Example 1 ethoxylate concentration = 0.294321 × 10 (% active ethoxylated surfactant) Thus, the concentration of ethoxylate in the composition of Example 1 is approximately 2.94.

  Example 1 concentration of sulfate = 0.18830 × 10 (% active ethoxylated surfactant) + 0.266845 × 4 (% active non-ethoxylated surfactant) Thus in the composition of Example 1 The concentration of sulfate is approximately 2.95.

  Examples 14, 16, and 17 are additional highly preferred embodiments. Example 15 is very similar in composition to Example 14, but has a different surfactant ethoxylate value. Example 15 has a calculated ethoxylate value below the claimed range and performs poorly with respect to coacervate formation. Example 18 similarly has a composition similar to the highly preferred Example 16, but also has a different surfactant ethoxylate value below the preferred range. Example 18 has poor coacervate formation and is not a preferred composition. These examples highlight the importance of ethoxylate ratios and show that relatively small changes in ethoxylate values have an unexpected and dramatic effect on the amount of coacervate. This observation by the inventor that only a very specific value of ethoxylate yields the optimum amount of coacervate, and also the dependence of this value on the polymer molecular weight is something specific or reasonable It is novel with respect to known techniques where the exact concentration and ratio of ethoxylated surfactants, for example, is often not ascertainable.
