BACKGROUND OF THE INVENTION Several approaches aimed at hair conditioning have been developed. A common method for providing hair conditioning benefits consists of the use of conditioning agents, for example, cationic polymers and surfactants, high melting point fatty compounds, low melting point oils, silicone compounds and mixtures thereof. It is known that most conditioning agents provide various conditioning benefits. For example, it is believed that some cationic surfactants, when used together with some high melting point fatty compounds and a Aqueous carrier, they offer a suitable gel matrix that provides a variety of conditioning benefits such as detangling sensation when applied to wet hair and feeling of softness and moisture when applied to dry hair. For example, WO 04/035016 describes conditioning compositions comprising: a cationic cross-linked polymer; stearomidopropyldimethylamine chloride or behenyl trimethylammonium chloride; cetyl / stearyl alcohols; and water. It is believed that the conditioning compositions provide improved conditioning benefits such as softness in wet substances while providing a detangling sensation on dry substances and a feeling of wetting on the substances during drying. However, there is a need to provide conditioning compositions that provide improved conditioning benefits, especially an improved detangling sensation when applied to wet hair. Based on the foregoing, there remains a need to provide conditioning compositions that provide improved conditioning benefits, especially an improved detangling sensation when applied to wet hair. None of the existing industries provide all the advantages and benefits of the present invention.

This term includes the expressions "consists of" and "consists essentially of". All percentages, parts and proportions are based on a total weight of the compositions of the present invention, unless otherwise specified.

The conditioning composition of the present invention can offer improved conditioning benefits, and a specially improved detangling sensation during its application to wet hair. It has been shown that: hair conditioning compositions with D spacing and the aforementioned yield strength provide improved wet conditioning benefits, especially an improved detangling sensation during application to wet hair as compared to compositions having a higher D-spacing and / or a lower yield strength. It is considered that the compositions with the D-spacing and the yield strength selected contain a greater amount of gel matrix with higher lamellar gel matrix content which provides a more dense lamellar gel matrix compared to the compositions with a spacing in D greater and / or lower yield limit. It has been shown that the combination of the D-spacing and selected yield strengths can adequately differentiate compositions that provide improved wet conditioning benefits from other compositions.

Lamellar gel matrix The composition of the present invention comprises a gel matrix including a lamellar gel matrix, especially a denser lamellar gel matrix. The lamellar gel matrix comprises a cationic surfactant, a high-point fatty compound of fusion and an aqueous carrier. The lamellar gel matrix is suitable to provide various conditioning benefits, such as a detangling sensation during application to wet hair and a feeling of softness and wetness on dry hair. Among the gel matrices, the lamellar gel matrix can provide an improved detangling sensation when applied to wet hair. Among the lamellar gel matrices, the denser lamellar gel matrix can provide an improved detangling sensation when applied to wet hair. To achieve the improved wet conditioning benefits, the cationic surfactant and the high melting point fatty compound are included at levels such that the weight ratio of the cationic surfactant to the high melting point fatty compound is in the range, preferably from about 1: 1 to 1: 10, more preferably from about 1: 1 to 1: 4. Preferably, the composition of the present invention comprises, by weight of the hair care composition, from about 60% to about 99%, preferably from about 70% to about 95% and more preferably about 80% to about 95% of a gel matrix, including a lamellar gel matrix to which it is possible to add optional ingredients such as silicones. The composition containing the aforementioned gel matrix amount with lamellar gel matrix content is characterized by having a yield strength of 30 Pa or more, as measured by the dynamic oscillation sweep method at a frequency of 1 Hz. and 26.7 ° C, by means of a rheometer available from TA Instruments with the name of method AR2000 using the parallel geometry with a diameter of 40 mm with a space of 0.0015 m (1500 mm). Preferably, the composition of the present invention, especially that which is used for rinsing, has a yield strength of about 30 Pa to about 90 Pa, more preferably from about 35 Pa to about 85 Pa, even more preferably from about 40 Pa to about 80 Pa, even more preferably from about 40 Pa to about 70 Pa. The composition containing the amount of gel matrix mentioned above is generally characterized by having a shear stress at a cutting speed of 950 s'1 from about 150 Pa to about 500 Pa, preferably from about 200 Pa to about 500 Pa and with greater Preference from approximately 250 Pa to approximately 500 Pa, measured at 26.7 ° C, by means of a rheometer available from TA Instruments under the name of method AR2000 using a geometry of the aluminum cone type of a 4 cm grade with a space of 5.7E- 5 m (57 μ? T?). The composition containing the gel matrix mentioned above is characterized by having a determined storage modulus G '. The storage module G 'is known as one of the most widely used viscoelasticity parameters. G 'is defined as the storage modulus and is part of the shear stress that is in phase with the deformation (by shear or shear) divided by the deformation under sinusoidal conditions. The composition containing the gel matrix mentioned above is characterized by having a G 'of from about 2200 Pa to about 10000 Pa, preferably from about 2500 Pa to about 8000 Pa, measured at 26.7 ° C and at a frequency of 1 Hz, per means of a rheometer available from TA Instruments under the name of method AR2000 using a parallel geometry of 4 cm, with a space of 0.0015 m (1500 μ ??). The composition containing the amount of gel matrix mentioned above is generally characterized by its dissolution profile. Compositions that contain a greater amount of gel matrix they need more time to homogenize with water when they are diluted. The composition containing the amount of gel matrix mentioned above can be characterized by measuring an amount of water that is not incorporated into the gel matrix. The lamellar gel matrix can be observed by scanning cryo-electron microscopy (cryo-SEM). Preferably, the present invention has a superior amount of lamellar gel matrix. The amount of lamellar gel matrix can be measured by analyzing the SEM image, for example by calculating the area of lamellar gel matrix per unit area. The gel matrix including a lamellar gel matrix can be detected by the differential scanning calorimetry measurement method (to which we will refer hereinafter using the acronym "DSC") of the composition. A graph of the profile obtained by the DSC method describes the chemical and physical changes of the swept sample that include a change in enthalpy or energy gradient when the temperature of the sample fluctuates. As such, the behavior of the phase and the interaction between the components of the hair conditioning compositions of the present invention can be understood through their DSC profiles. The DSC measurement of the compositions of the present invention can be carried out by any suitable instrument available. For example, the DSC measurement can be conveniently performed using a Seiko 6000 for DSC instrument available from Seiko Instruments Inc. In a traditional measurement method, a sample is prepared by sealing an appropriate amount of composition in a container for measurements with the DSC method and then It is sealed. The weight of the sample is recorded. A control sample is also prepared, that is, an unsealed sample from the same container. The sample and the control sample are placed inside the instrument and run under the same measurement conditions of about -50 ° C to about 130 ° C, at a heating rate of about 1 ° C minute to about 10 ° C / minute. The area of the peaks is then calculated and divided by the weight of the sample to obtain the enthalpy change in mJ / mg. The position of the peaks is identified by the upper peak position. In a preferred composition that has a greater amount of gel matrix, the DSC profile shows a formation peak of more than about 3 mJ / mg, more preferably from more than about 6 mJ / mg to about 10 mJ / mg. The DSC profile of a preferred composition shows a single peak including a peak peak temperature of about 55 ° C to about 75 ° C. The DSC profile of the preferred composition does not show peaks above 3 mJ / mg, more preferably does not exhibit peaks greater than 2.5 mJ / mg, even more preferably does not exhibit peaks greater than 2 mJ / mg at a temperature of 40 ° C at 55 ° C, since the existence of peaks at temperatures of 40 ° C to 55 ° C means that there are fatty compounds of high melting degree and / or cationic suryactants that are not incorporated in the gel matrix. It is considered that a composition that is formed predominantly with said gel matrix, exhibits a relatively stable phase behavior in a temperature range of about 40 ° C to about 55 ° C. In highly preferred compositions, the DSC profile shows a single peak with a peak peak temperature of about 67 ° C to about 73 ° C, at about 8 mJ / mg, and does not exhibit peaks greater than 2 mJ / mg at 40 ° C. Approximately 65 ° C. It is also possible to detect the presence of the lamellar gel matrix by D-spacing. The compositions of the present invention have a D-spacing value of 3.3E-8 m (33 nm) or less, preferably 3.1 E-8. m (31 nm) or lower, more preferably 2.8E-8 m (28 nm) or less. The D-spacing in the present invention refers to the distance between two lamellar bilayers plus the width of a lamellar bilayer as described in figure 1. Therefore, the spacing in D is defined according to the following equation: spaced in D = d agUa + d b¡capa It is possible to measure the D-spacing using a small high-flux X-ray diffusion angle instrument, marketed by PANalytical under the trade name of SAXSess, under typical conditions of small X-ray diffusion angle (SAXS) measurement in a range q (q = 4 ^ sin (6) where? is the wavelength and T is half the diffusion angle) of 0.06 < q / nm "1 <27 which corresponds to 0.085 <29 / degree <40. All data is calibrated by transmission by monitoring the intensity of the attenuated primary light beam and normalizing it so as to form a unit, to obtain from Thus, the relative intensity for different samples Transmission calibration allows us to adequately subtract the water contribution of the net diffusion of the sample.D spacing is calculated by the following equation (known as the Bragg equation): n? = 2dsin (?), where n is the number of lamellar bilayers It has been demonstrated that: hair conditioning compositions with a lower D-spacing (ie, a denser sheet lamellar gel matrix) and the yield strength selected above, provide improved wet conditioning benefits, especially a feeling improved detangling when applied to wet hair compared to compositions having a greater D-spacing and / or lower yield strength. It is considered that compositions with a D-spacing and a selected yield strength contain a greater amount of gel matrix with a higher content of sheet-like lamellar gel matrix, compared to compositions having a greater D-spacing and / or a limit of minor creep. It has been shown that the combination of the D-spacing and selected yield strengths can adequately differentiate compositions that provide improved wet conditioning benefits from other compositions. In addition to the D-spacing and the yield strength selected above, the preferred amount of gel matrix, and / or the preferred amount of lamellar gel matrix help to differentiate the composition of the present invention from other compositions. It has also been shown that: the preferred cationic surfactants of the present invention can provide improved wet conditioning benefits, as compared to other cationic surfactants such as the tertiary amine, tertiary amine salt, and long chain dialkyl quaternary ammonium salt.

Preferably, considering the stability of the gel matrix, the composition of the present invention is practically free of cationic surfactants and anionic polymers. In the present invention, the term "practically free of anionic surfactants and anionic polymers" means that the composition contains 1% or less, preferably 0.5% or less, more preferably 0% of the total anionic polymers and anionic surfactants. To achieve improved wet conditioning benefits, it is preferable that the composition contains the cationic surfactant and the high melting point fatty compound at a level such that the weight ratio of the cationic surfactant to the high melting point fatty compound is in the range of about 1: 1. at 1:10, more preferably from about 1: 1 to 1: 4. To achieve improved wet conditioning benefits, especially when the composition contains long chain monoalkyl quaternary ammonium salts as a cationic surfactant, it is also preferable that the composition contains the long chain monoalkyl quaternary ammonium salt and a fatty compound of high melting point at levels such that the total amount of the long chain monoalkyl quaternary ammonium salt and the high melting point fatty compound is 5% or greater, more preferably 6.5% or higher and even more preferred 7.5% or greater by weight of the composition. To form the gel matrix including the lamellar gel matrix, it is preferable to prepare the composition by the following method: Water is heated at a temperature of at least about 70 ° C, preferably between about 80 ° C and about 90 ° C. Cationic surfactant and high-melting fatty compound combine with water to form a mixture. The temperature of the mixture is preferably maintained at a temperature higher than that of the cationic surfactant and at the melting temperature of the high melting point fatty compound and the mixture is homogenized in its entirety. After mixing until no solids are observed, the mixture is cooled gradually (for example, at a rate of about 1 ° C / minute to about 5 ° C / minute) at a temperature below 60 ° C, preferably below 55 ° C. During this gradual cooling process, a significant increase in viscosity is observed at a temperature between about 55 ° C and about 75 ° C. This indicates the formation of a gel matrix that includes a lamellar gel matrix. Then the additional components are combined with the gel matrix and these are cooled to room temperature.

Among the variety of cationic surfactants are preferred: (i) a long chain monoalkyl quaternary ammonium salt and an anion wherein the anion is selected from the group comprising C 1 -C 4 alkyl sulfate, such as, for example, methosulfate and ethosulfate and mixtures of these; and (ii) an alkyl quaternary ammonium salt. The cationic surfactant of the present invention is included in the composition at a weight level of from about 0.1% to about 10%.

Such "different cationic surfactants" include, for example, long-chain monoalkyl quaternary ammonium salts wherein the anion is not a C 1 -C 4 alkyl sulfate, tertiary amine, tertiary amine salts, and dialkyl quaternary ammonium salts long chain In the present invention, the term "practically free of other cationic surfactants" means that the composition contains 1% or less, preferably 0.5% or less, more preferably 0% of the total of said different cationic surfactants. (i) Long chain monoalkyl quaternary ammonium salt cationic surfactant One of the preferred cationic surfactants of the present invention is a long chain monoalkyl quaternary ammonium salt and an anion, wherein the anion is selected from the group comprising C 1 -C 4 alkyl sulfate such as methosulfate and ethosulfate, and mixtures thereof. It has been shown that: by using selected anions that have higher ionic binding strength compared to other anions, such as chloride, cationic surfactants have a reduced hydration radius; said reduced hydration radius produces a more dense lamellar gel matrix, that is, it reduces the distance between a lamellar bilayer and another. The long chain monoalkyl quaternary ammonium salts which are used herein are those having the following formula (I): 71 R .0 X R74 (i) wherein one of R, R, R and R is selected from an aliphatic group of 16 to 40 carbon atoms or of an aromatic, alkoxy, polyoxyalkylene, alkylamido, hydroxyalkyl, aryl or alkylaryl group having up to 40 carbon atoms; the rest of R71, R72, R73 and R74 are indistinctly selected from an aliphatic group with about 1 to 8 carbon atoms or an aromatic, alkoxy, polyoxyalkylene, alkylamido, hydroxyalkyl, aryl or alkylaryl group having up to about 8 carbon atoms. carbon; and X "is a salt forming anion selected from C 1 -C 4 alkyl sulfate such as methosulfate and ethosulfate and mixtures thereof Aliphatic groups may contain, in addition to carbon and hydrogen atoms, ether bonds and other groups such as the amino groups The longer chain aliphatic groups, for example, those of about 16 carbon atoms or more, can be saturated or unsaturated, preferably one of R71, R72, R73 and R74 is selected from a alkyl group of 16 to 40 carbon atoms, more preferably of 18 to 26 carbon atoms, still more preferably 22, and the remainder of R71, R72, R73 and R74 is indifferently selected from CH3, C2H5, C2H4OH, CH2C6H5, and mixtures of these It is believed that these long-chain monoalkyl quaternary ammonium salts can provide a dazzling feeling in damp hair and that the hair is limp and shiny compared to the quaternary ammonium salts io of several long chain alkyls.
