MULTIPHASE COMPOSITIONS FOR PERSONAL CLEANING THAT UNDERSTAND A SPARKLING CLEANING PHASE AND A PHASE STRUCTURED NON-SPARKING AQUEOUS CROSS REFERENCE TO A RELATED APPLICATION This application claims the benefit of the US provisional application. no. 60 / 532,798 filed on December 24, 2003 and the US provisional application. no. 60 / 576,199 filed on June 2, 2004.

FIELD OF THE INVENTION The present invention relates to multiphase compositions for personal cleansing comprising a foaming cleaning phase and a non-foaming structured aqueous phase wherein the two phases are packaged in physical contact while remaining stable over time.

BACKGROUND OF THE INVENTION It has been found that it is difficult to achieve that a foaming cleaning phase is in physical contact with a non-foaming structured aqueous phase and that at the same time stability is maintained for any period. Physical contact between a non-foaming structured aqueous phase and a foaming cleansing phase generates a situation in which those phases are thermodynamically unstable. An attempt to provide a non-foaming structured aqueous phase and a foaming cleaning phase from a personal cleansing product while maintaining stability could be the use of a double chamber package. These containers comprise cleaning compositions and separate aqueous non-foaming compositions, and allow the two compositions to be dispensed simultaneously in a single or double stream. In this way, the structured non-foaming compositions and separate foaming cleansers remain physically separate and stable during prolonged storage and just before application, but are then mixed during or after the delivery to provide conditioning and cleaning benefits from a system physically stable. Although these dual-chamber supply systems provide improved cleaning benefits over conventional systems, it is often difficult to obtain consistent and uniform performance due to the unequal shipping ratio between the foaming cleaning phase and the non-foaming structured aqueous phase from these double chamber packaging. In addition, these packaging systems add a considerable cost to the finished product. Accordingly, there remains a need for stable personal cleansing compositions that provide improved foam duration and improved foaming characteristics, and skin benefits such as a silky feel, and smoothness and improved smoothness.

It has now been found that multiphase personal cleansing compositions can be formulated comprising two phases in physical contact that maintain their stability over time. The multiphase personal cleansing compositions described in the present invention comprise a foaming cleansing phase and an aqueous phase. structured, non-foaming that are packaged in physical contact and yet remain stable. The compositions of the present invention also provide improved aesthetics through the appearance of multiple phases and better skin feel during and after their application. It has been found that these compositions can be formulated in two separate hydrophilic phases which are in physical contact and do not limit the soapy capacity and stability of the product. It has also been found that the multiphase compositions for personal cleansing described herein can be formulated with selected dermoactive agents that provide the skin with better chronic benefits. These compositions comprise a foaming cleansing phase containing a cleansing surfactant and at least one additional non-foaming structured aqueous phase, wherein a dermoactive agent can be found in one or both phases at the same time and wherein the foaming cleansing phase and the phase Structured aqueous non-foaming agents are packaged in physical contact while they remain stable over time.

These and other essential limitations of the compositions and methods of the present invention, as well as many of the optional ingredients suitable for use herein are described in detail below. As used herein, the terms "multi-phase" or "multiphase" refer to the fact that the foaming cleaning phase and the structured non-foaming aqueous phase in the present occupy separate physical spaces, but distinct within the container in which they are stored, but they are in direct contact with each other (ie they are not separated by a barrier and they are not emulsified or mixed at a considerable level). In a preferred embodiment of the present invention, the "multiphase" personal cleansing compositions comprising the foaming cleansing phase and the Non-foaming structured aqueous phase are present within the container as a visually distinctive pattern.

In this document, the term "separated" means that there is no substantial mixture of the phases, which can be observed with the naked eye before dispensing the composition. In this description, the term "personal cleansing composition" refers to compositions intended for topical application on the skin or hair. As used herein, the term "phases" refers to a region of a composition having an average composition, as opposed to another region having a different average composition, wherein the regions can be observed with the naked eye. This would not prevent the different regions from being able to understand two similar phases wherein one phase could comprise pigments, dyes, particles, and various optional ingredients and therefore a region of a different average composition.

Form of the product The personal cleansing compositions of the present invention are usually in the form of a liquid. In this document, the term "liquid" means that the composition has a certain degree of fluidity. Therefore, the term "liquids" may include liquid, semi-liquid, cream, lotion or gel compositions, which are intended to be applied topically on the skin. Typically, the compositions exhibit a viscosity equal to or greater than about 3 Pa.s (3000 cps) to about 1000 Pa.s (1, 000,000 cps), in accordance with the Method of Viscosity Measurement described below. In addition, the ratio of the foaming cleaning phase to the non-foaming structured aqueous phase is from about 10: 1 to about 1: 10. The compositions comprise a foaming cleaning phase and a structured non-foaming aqueous phase which are described in detail below. In a preferred embodiment of the present invention, the multi-phase composition for personal cleansing has at least two visually distinct phases wherein at least one phase is visually distinct from a second phase.

Structured aqueous non-foaming phase The structured non-foaming aqueous phase of the compositions of the present invention comprises a water and water structuring agent. The non-foaming structured aqueous phase can be hydrophilic and in a preferred embodiment, it is a hydrophilic, gelled aqueous phase. In addition, the structured non-foaming aqueous phase of the invention generally comprises less than about 5%, preferably less than about 3%, and more preferably less than about 1% of a surfactant by weight. In an embodiment of the present invention, the non-foaming structured aqueous phase does not contain surfactant. The non-foaming structured aqueous phase of the personal care compositions preferably produces a total volume of foam no greater than about 500 mL, more preferably no greater than about 400 mL and even more preferably no greater than about 350 mL measured with the foam volume determination test described below. The structured non-foaming aqueous phase of the compositions for personal care preferably it produces an instantaneous volume of foam no greater than about 150 mL, preferably no greater than about 130 mL, and even more preferably no greater than about 110 mL measured with the Foam Volume Determination Test described below. Preferably, the non-foaming structured aqueous phase has a yield point of at least about 0.1 Pa, preferably of at least about 1 Pa and more preferably of at least about 10 Pa measured with the method of determining the yield point described later. Preferably, the non-foaming structured aqueous phase exhibits a water mobility of less than about 2.5 seconds, more preferably less than about 2 seconds and even more preferably less than about 1 second measured with the Water Mobility Determination Method described later. Preferably, the non-foaming structured aqueous phase exhibits a correlated turbidity of less than about 50%, more preferably less than about 30%, still more preferably less than about 20% and with an even greater preference of less than about 10% measured with The method of determining the correlated turbidity index described below. The non-foaming structured aqueous phase has a preferred rheology profile as defined by the consistency value (k) and the cut-off index (n). The preferred consistency values of the non-foaming structured aqueous phase are approximately 1 to about 10000 Pa.s / (1 / s) (about 10 to about 100,000 poise / (1 / s)), preferably from about 1 to about 1000 Pa.s / (1 / s) (about 10 to about 10,000 poise) / (1 / s)), and more preferably from about 10 to about 100 Pa.s / (1 / s) (about 100 to about 1000 poise / (1 / s)). The cutting index of the non-foamed structured aqueous phase generally ranges from about 0.1 to about 0.8, preferably from about 0.1 to about 0.5, and more preferably from about 0.20 to about 0.4. The values of cut index (n) and consistency (k) are widely accepted and known industry standards used to inform the viscosity profile of materials whose viscosity is a function of an applied cut index. The viscosity (μ) of a non-foaming structured aqueous phase can be characterized by the application of a cutting index and the subsequent measurement of the obtained cutting voltage or vice versa in a programmed manner using a rheometer, such as a TA Instruments AR2000 (TA Instruments, New Castle, DE, USA 19720). The viscosity is determined in the following manner based on different cutting rates. First, the non-foaming structured aqueous phase is obtained whose composition and properties coincide with those corresponding to the multiphase composition for personal care. That is, the composition is processed in a similar way so that, for example, it crystallizes at an index almost equal, if the sample comprises crystals. Before combining the structured non-foaming aqueous phase in the multiphase composition, an aliquot of that phase can be obtained, a common practice for people of skill in the industry. Also, the non-foaming structured aqueous phase can be recovered from the multiphase personal care composition, for example by centrifugation, pipetting, sieving, rinsing or other suitable methods to recover the structured non-foaming aqueous phase. The AR2000 rheometer is programmed to cut the sample when the voltage rises from approximately 0.1 Pa to approximately 1000 Pa in a range of 5 minutes to 25 degrees Celsius. In general, a 4 cm parallel plate geometry with a gap of 1 mm is used, although that gap may be larger or smaller as needed; for example, when the structured non-foaming aqueous phase contains large particles, it may be necessary for that gap to be larger. In the test, a cut-off index of at least 100 1 / s is obtained or the test is repeated with a higher final tension value while maintaining the programmed voltage index in approximately 1.25 minutes per 10 voltage units. These results are adjusted with the following power law model. The data is included in the cut region by plotting the viscosity data and cut-off index in a graphical representation of the records using only the data of the region in which the cut-off index is ascending and the viscosity is descending in a stable way For example not it is considered an initial plateau region at a low shear stress where little flow occurs. In general, a viscosity whose cutoff index varies between approximately 0.1 and 10.0 1 / s is adequate and sufficient data points are taken for adjustment to the widely accepted power law model (see for example: Chemical Engineering ), by Coulson and Richardson, Pergamon, 1982 or Transport Phenomena (Transport Phenomenon), by Bird, Steward and Lightfoot, Wiley, 1960): μ = k (? ') (n-1) The value obtained for the slope of the records is (n-1) where n is the cut index and the value obtained for k is the consistency value in Pa.s / (1 / second) (poise / (1 / second).)

Non-exhaustive examples of cationic deposition polymers for use in the personal cleansing composition can be polymers of polysaccharide such as cationic cellulose derivatives. Preferred cationic cellulose polymers are the hydroxyethylcellulose salts reacted with substituted trimethylammonium epoxide, mentioned in the industry (CTFA) as Polyquatemium 10 which is available from Amerchol Corp.

The cationic polymers herein are soluble in the foaming cleansing phase, or are preferably soluble in a complex coacervation phase in the multiphase personal cleansing composition formed by the cationic deposition polymer and the anionic surfactant component described above. Complex coacervates of the cationic deposition polymer can also be formed with other charged materials in the personal cleansing composition. The formation of the coacervate depends on a variety of criteria, such as molecular weight, component concentration, ionic strength (including modification of ionic strength, for example by the addition of salts), the charge density of the components cationic and anionic, pH, and temperature. Coacervated systems and the effect of these parameters are described for example in J. Caelles et al., "Anionic and Cationic Compounds in Mixed Systems", Cosmetics & Toiletries (Cosmetics and toiletries), Vol. 106, April 1991, p. 49-54, C. J. van Oss; "Coacervation, Complex-Coacervation and Flocculation" (Coacervation, complex-coacervation and flocculation), J. Dispersion Science and Technology, Vol. 9 (5.6), 1988-89, p. 561-573 and D. J. Burgess; "Practical Analysis of Complex Coacervate Systems" (Practical Analysis of Complex Coacervate Systems), J. of Colloid anti Interface Science (Journal of Colloid Anti-interference Science), Vol. 140, no. 1, November 1990, p. 227-238 whose descriptions are incorporated herein by reference.

It is believed to be particularly advantageous if the cationic deposition polymer is present in the personal cleansing composition in a coacervate phase, or which forms a coacervate phase by applying the cleansing composition to the skin or by rinsing it out of the skin. It is believed that complex coacervates deposit more easily on the skin, which results in a better deposit of beneficial materials. Therefore, it is generally preferred that the cationic deposition polymer exists in the personal cleansing composition as a coacervate phase or that it forms a coacervate phase in dilution. If it is not yet a coacervate in the personal cleansing composition, the cationic deposition polymer will preferably exist as a complex coacervate in the cleaning composition in dilution with water. The techniques for the analysis of complex coacervate formation are known in the industry. For example, centrifugation analyzes of the personal cleansing compositions can be used at any chosen stage of dilution to identify whether a coacervate phase has been formed.

A person of skill in the industry knows that these materials can be used in the quantities necessary to provide the desired benefit. To the extent that any optional ingredient described herein includes specific materials described above as water structuring agents or sheet structuring agents, those materials will be considered as water structuring agents or sheet structuring agents for the purposes of present invention. Test methods Foam volume test The foam volume of a multiphase composition for personal cleansing or of a structured non-foaming aqueous phase or foaming cleansing phase of a personal cleansing composition is measured with a graduated cylinder and a rotating drum apparatus. A graduated 1000 mL cylinder marked in 10 mL increments and 36.8 cm (14.5 inches) in height at the 1000 mL mark is used from the inside of its base (eg Pyrex No. 2982). Distilled water is added to the graduated cylinder (100 grams at 23 ° C). The cylinder is fixed in a rotating device that holds the cylinder with a rotation axis that cuts transversely the center of the graduated cylinder. One gram of the total personal cleaning composition is added (0.5 g of the foaming cleaning phase and 0.5 g of the structured non-foaming aqueous phase when measuring the total product, or 1 g of the foaming cleaning phase or the non-foaming structured aqueous phase when measuring the foaming cleaning phase or the structured non-foaming aqueous phase only) in the graduated cylinder and the cylinder is capped. The cylinder is rotated at a speed of 3.14 rad / s (10 revolutions in approximately 20 seconds) and stopped in a vertical position to complete the first rotation sequence. A timer is set to allow 30 seconds for the generated foam to empty. After 30 seconds of this drainage, the first volume of foam is measured at the nearest 10 mL mark by recording the height of the foam in mL to the base (including any water that has been drained to the bottom on which the foam floats). ). If the upper surface of the foam is uneven, the lowest height at which it is possible to see through the half of the graduated cylinder is the first volume of foam (mL). If the foam is so rough that only one or a few foam cells ("bubbles") reach through the entire cylinder, the height at which at least 10 foam cells are required to fill the space is the first volume of foam , also in mL up from the base. The largest one-inch foam cells in any dimension, no matter where they occur, are called unfilled air instead of foam. The foam that accumulates in the upper part of the graduated cylinder, but it is not emptied, it is also included in the measurement if the foam of the upper part is in its own continuous layer, by means of the addition of the mL of foam accumulated there using a ruler to measure the thickness of the layer, mL of foam measured up from the base. The maximum height of the foam is 1000 mL (even if the total height of the foam exceeds the 1000 mL mark on the graduated cylinder). One minute after finishing the first rotation, a second rotation sequence is started which is identical in speed and duration to the first rotation sequence. The second volume of foam is recorded in the same way as the first, after the same 30 seconds of drainage time. A third sequence is completed and the third volume of foam is measured in the same way, with the same pause between each drain and taking the measurement. The results of the foam after each sequence are added together and the total foam volume is determined as the sum of the three measurements, in mL. The instantaneous volume of foam is the result of the first rotation sequence only, in mL, ie the first volume of foam. The compositions according to the present invention perform significantly better in this test than similar compositions in conventional emulsion form. Viscosity Test Method Here, the cone-plate viscometer model DV-II + from Wells-Brookfield can be used to determine the viscosity of the structured non-foaming aqueous phase and the foaming cleansing phase. The Determination is carried out at 25 ° C with the cone measuring system of 2.4 cm and 2 ° with a 0.013 mm gap between the two small terminals on the respective cone and plate. To perform the measurement, 0.5 mL of the sample is injected and the cone is rotated at a determined speed of 0.1 rad / s (1 rpm). The resistance to rotation of the cone produces a torque that is proportional to the shear stress of the sample. liquid The torque reading is read 2 minutes after the sample is loaded and computed with the viscometer in absolute centipoise units (mPa * s) based on the geometric constant of the cone, the rotation rate and the torque related effort. Method of determination of the yield point To determine the yield point of the structured non-foaming aqueous phase or the foaming cleaning phase, a controlled voltage rheometer TA Instruments AR2000 can be used. For the purposes of the present, the yield point is the tension necessary to produce a 1% deformation in the non-foaming liquid structured aqueous phase or in the foaming cleaning phase. The determination is made at 25 ° C with the measuring system of parallel plate 4 cm in diameter and 1 mm apart. The determination is made by means of the programmed application of a shear stress (usually from approximately 0.1 Pa to approximately 500 Pa 0) in a 5 minute interval. This amount of stress results in deformation of the sample, whereby a stress curve can be created with respect to tension. The pour point of the non-foaming liquid structured aqueous phase can determine from this curve. The non-foaming liquid structured aqueous phase or the foaming cleansing phase are measured before combining them into the composition or thereafter, separating the compositions by suitable physical separation means such as centrifugation, pipetting, mechanical cutting, rinsing, filtering, or other means. Method of determining the mobility of water The mobility of the water of the non-foaming structured aqueous phase is determined by means of the pulse NMR method. To measure water mobility, a Maran Ultra Low Field pulse NMR device, 23 MHz, pulse sequence CPMG, with thermal control regulated at 24-29 ° C is used. First the sample of the structured non-foaming aqueous phase is placed in the pulsed NMR test tube and then exposed to the excitation of a pulse radiofrequency (23 MHz). The data acquisition and processing parameters are listed in the following table.

ACQUISITION PARAMETERS 90 degree pulse 6.9 μs 180 degree pulse 13.5 μs Probe timeout 4.0 μs Receiver timeout 3.0 μs Spectrometer frequency 23.10 MHz Compensation from SF -25116.83 Hz Filter width 1,000,000 Hz Retention time 1 μs Points per echo 1 Amount of echoes 8192 Number of scans 8 Receiver gain 0.50% Relaxation delay 10,000,000 μs Pulse separation 90-180 degrees 100.0 μs 90-degree pulse phase list 0213 Receiver phase list 0213 180-degree pulse phase list 1122 Stabilization sweeps 2 PROCESSING PARAMETERS Widening of the line 0.00 Amount of smoothing points 0 Phase of the detector 2.81 Phase correction of zero order 0.00 First order phase correction 0.00 Pivot for first order correction 0 Relative peak of the peak detector 4.0% Factor of Rayleigh Peak Identifier 50% P Factor of Peak Identifier 0 RESULTS Percentage reported area and time T2 of the highest peak containing water.

The relaxation decay constant (time T2) is calculated by evaluating the decay profile of the signal. The time T2 (in seconds) of the largest peak containing water is reported as Mobility of water. A high relaxation time T2 indicates high water mobility. A low relaxation time T2 indicates low water mobility (ie, a more structured system). Method of determining the correlated turbidity index The color measurement system of Macbeth, Gretag Macbeth Model 7000 with an optical head of spherical geometry is used to apply the method of determination of the correlated turbidity index. The Reflectance and transmittance modes of the instrument must be calibrated. These two calibrations are used to obtain the correlated turbidity index. To prepare the sample, centrifuge the composition at 314 rad / s (3000 rpm) for approximately 3 minutes to eliminate any air bubbles present. Pour the composition into an optical cell, slowly so that air bubbles do not form. If these are formed, allow the sample to settle for 30 minutes at room temperature to remove air. If the air bubbles do not disappear, first empty the cell, clean it and dry it and then refill it as before. Remove any portion of the composition spilled on the external surface of the cell, for example with a cloth. The sample of the composition must be within 2 ° C of the original calibration temperature. When the sample is ready, the instrument should be in the usual laboratory configuration with Clluminate, an observation angle of 2 degrees and no average. Then, configure the instrument in "CRIOLL". To do this, the specular component is changed to "included", the UV to "excluded" and the measurement mode to "reflectance". These changes are made without a sample cell holder inside the instrument. Then, place a large sample cell holder without the sample inside the instrument and calibrate it according to the instructions on the screen. Change the measurement mode to "transmission" and the instrument will display the BTIOLL configuration. Calibrate the instruments following the indications that appear on the screen.

Then, move to measurement mode, "correlated turbidity". The instrument configuration will now be XHIOLL. Calibrate the instrument following the instructions that appear on the screen. The new configuration of the instrument will be CHIOLL. The operator must click on the index icon in the toolbar so that the viewer shows the results of the correlated turbidity. Make an empty cell as a pattern. Fill the optical cell with the sample of the composition to be analyzed and verify that there are no air bubbles. Prepare as a test and report the results of the turbidity correlated in percentages. The instrument must be calibrated at least every 8 hours. Method of use The multi-phase personal care compositions described in the present invention are preferably applied topically to the desired area of the skin or hair in an amount sufficient to effectively deliver the skin cleansing agent and beneficial agents for the skin. skin on the application surface. The compositions can be applied directly to the skin or indirectly using a tassel to clean, a washcloth, a sponge or other implement. The compositions are preferably diluted with water before, during or after topical application, and subsequently rinsed or cleaned from the applied surface, preferably rinsed off the applied surface using water or a water insoluble substrate in combination with Water.

Manufacturing Method The multi-phase personal cleansing compositions described in the present invention can be prepared by any known technique or in any other effective way, suitable to elaborate and formulate the desired multi-phase product form. It is effective to combine the filling technology of toothpaste tubes as a rotating stage design. In addition, the present invention can be prepared in accordance with the method and apparatus described in U.S. Pat. no. 6,213,166. The method and the apparatus are used to fill a single container with two or more compositions with a spiral configuration. The method requires at least two nozzles to fill the container. The container is placed in a static mixer and rotated until the composition is introduced into the container. Another effective way consists in combining at least two phases by first placing the separate compositions in individual storage tanks having a pump attached and a hose. The phases are pumped in predetermined quantities in a single combination section. Then, the phases move from the combination sections to the mixing sections where the phases are mixed, so that this single resulting product shows a distinctive pattern of the phases.
