CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority to and all the advantages of U.S. Provisional Patent Application No. 61/729,024, filed on November 21, 2012, the content of which is incorporated herein by reference.

TECHNICAL FIELD

[0002] This disclosure relates to cosmetic compositions comprising an emulsion (E), and at least one cosmetic ingredient (C), in a cosmetically acceptable medium.

BACKGROUND

[0003] Emulsions are a useful means compatibilising initially incompatible materials. Simple emulsions are usually at least composed of an external, continuous phase and an internal, dispersed phase and at least one surface active agent used to compatibilise the distinct phases. Emulsions of various ingredients may be used in cosmetic applications, where they allow incorporation of incompatible materials in a larger matrix such as vitamins in a skin care cream, or conditioning polymers in a shampoo.

[0004] There is a continuous need to provide for emulsions which lower the environmental impact of transport, by reducing the amount of water contained in the emulsion. There is a continuous need to provide for emulsions which are not detrimental to the health of consumers by reducing the amount of surfactant contained in the emulsion or by reducing the amount of biocide.

[0005] There is a continuous need to simplify the formulator' s work by providing for emulsions which are easy to use, pourable, while at the same time containing a limited amount of unnecessary ingredients which allow larger latitude for useful ingredients. That is, limiting the amount of water to allow incorporation of more active ingredients such as dyes, care agents and the like.

[0006] There is an ongoing need for emulsions of conditioning polymers which provide for care of keratinous substrates.

BRIEF SUMMARY OF THE INVENTION

[0007] The present invention relates to cosmetic compositions comprising bi-modal water continuous emulsions. In particular, the present disclosure relates to cosmetic compositions comprising a bi-modal water continuous emulsion (E) comprising at least 70 weight percent of: a first dispersed phase containing a hydrophobic oil, wherein the hydrophobic oil is provided as a non-emulsified hydrophobic oil, a second dispersed phase containing a silicone, wherein the silicone is provided from a water continuous silicone emulsion containing at least one surfactant; and at least one cosmetic ingredient (C), in a cosmetically acceptable medium.

[0008] The invention also relates to a process to prepare the cosmetic compositions and uses of said cosmetic compositions.

DETAILED DESCRIPTION OF THE INVENTION

[0009] The present invention relates to cosmetic compositions comprising emulsions. In particular, the present disclosure relates to cosmetic compositions comprising a bi-modal water continuous emulsion (E) comprising at least 70 weight percent of: a first dispersed phase containing a hydrophobic oil, wherein the hydrophobic oil is provided as a non-emulsified hydrophobic oil, a second dispersed phase containing a silicone, wherein the silicone is provided from a water continuous silicone emulsion containing at least one surfactant; and at least one cosmetic ingredient (C), in a cosmetically acceptable medium.

[0062] The water continuous silicone emulsion (B) may be selected from those considered in the art to be a "macro" or "micro" emulsion. In other words, the average particle size of the water continuous emulsion may vary from 0.001 to 1000 μιη, alternatively from 0.01 to 20 μιη, or alternatively from 0.02 to 10 μιη.

[0063] The water continuous silicone emulsion (B) is a microemulsion having an average particle size of less than 100 nm.

[0064] The water continuous silicone emulsion (B) may be considered an "emulsion polymer", in other words, an emulsion formed by emulsion polymerization techniques. Examples of suitable silicone emulsions produced by emulsion polymerization techniques are taught in US2891920, US3294725, US5661215, US5817714, and US6316541, which are incorporated herein by reference. [0065] The water continuous silicone emulsion (B) may be a mechanical emulsion. As used herein, mechanical emulsions refer to those emulsion in the art produced by using mechanical energy (such as from high shearing forces). Examples of silicone emulsions produced by mechanical techniques are taught in US6395790, which is incorporated herein by reference.

[0066] The water continuous silicone emulsion may be prepared using suspension polymerization techniques. Examples of silicone emulsions produced by suspension polymerization techniques are taught in US4618645, US6248855, and US6395790.

[0067] The present bi-modal water continuous emulsion (E) may be prepared by a process comprising:

I) forming a mixture comprising;

A) 100 parts by weight of a hydrophobic oil,

B) 1 to 1000 part by weight of a water continuous silicone emulsion having at least one surfactant,

II) admixing additional quantities of the water continuous emulsion and/or water to the mixture from step I) to form a bi-modal emulsion.

[0068] Component (A) in step I) of the above process may be any hydrophobic oil as described above as component (A) in the first dispersed phase.

[0069] Component (B) in step I) of the above process may be any water continuous silicone emulsion as described above as component (B) in the second dispersed phase.

[0070] Mixing in step I) can be accomplished by any method known in the art to effect mixing of high viscosity materials. The mixing may occur either as a batch, semi-continuous, or continuous process. Mixing may occur, for example using, batch mixing equipments with medium / low shear include change-can mixers, double -planetary mixers, conical-screw mixers, ribbon blenders, double-arm or sigma-blade mixers; batch equipments with high-shear and high- speed dispersers include those made by Charles Ross & Sons (NY), Hockmeyer Equipment Corp. (NJ); batch equipments with high shear actions include Banbury-type (CW Brabender Instruments Inc., NJ) and Henschel type (Henschel mixers America, TX). Illustrative examples of continuous mixers / compounders include extruders single-screw, twin-screw, and multi- screw extruders, co-rotating extruders, such as those manufactured by Krupp Werner & Pfleiderer Corp (Ramsey, NJ), and Leistritz (NJ); twin-screw counter-rotating extruders, two- stage extruders, twin-rotor continuous mixers, dynamic or static mixers or combinations of these equipments. [0071] The temperature and pressure at which the mixing of step I) occurs is not critical, but generally is conducted at ambient temperature and pressures. Typically, the temperature of the mixture will increase during the mixing process due to the mechanical energy associated when shearing such high viscosity materials.

[0072] Typically 1 to 1000 parts by weight of the water continuous emulsion are mixed for every 100 parts by weight of component (A) in the step I) mixture, alternatively from 5 to 500 parts per 100 parts by weight of component (A) in the step I) mixture, or alternatively from 5 to 100 parts per 100 parts by weight of component (A) the step I) mixture.

[0073] Step I) may involve forming a mixture consisting essentially of;

A) 100 parts by weight of a hydrophobic oil,

B) 1 to 1000 parts by weight of a water continuous emulsion having at least one surfactant. In this embodiment, the mixture formed in step I) is "essentially free" from any other surfactant compounds or components other than components (A) and (B). As used herein, "essentially free" means no other surfactant compounds are added to the mixture formed in step I), other than the surfactant(s) present in (B) the water continuous emulsion.

[0074] Step II) of the process involves admixing additional quantities of the water continuous emulsion and/or water to the mixture from step I) to form a bi-modal emulsion.

[0075] The amount of the additional quantities of the water continuous emulsion and/or water used in step II) may vary depending on the selection of components (A) and (B). Typically the amount of additional water continuous emulsion and/or water admixed in step II) of the present process may vary from 1 to 1000 parts by weight of the step I) mixture, alternatively from 5 to 500 parts per 100 parts by weight, or alternatively from 5 to 100 parts per 100 parts by weight.

[0076] In step II) of the present process, additional quantities of the water continuous emulsion may be used alone, or alternatively be combined with varying quantities of water. Alternatively, additional quantities of water may be added alone without any additional quantities of the water continuous emulsion. The selection of using additional quantities of the water continuous emulsion alone, in combination with varying amounts of water, or water alone will depend on the initial selection of the water continuous emulsion and the desired physical properties of the resulting bi-modal emulsion. For example, high solids bi-modal emulsions may be prepared with only the addition of the water continuous emulsion. Conversely, low solids bi-modal emulsions may require the addition of water as well.

[0077] The water continuous emulsion and/or water is added to the mixture from step I) at such a rate, with additional mixing, so as to form an emulsion of the mixture of step I). The water continuous emulsion added to the mixture from step I) may be done in incremental portions, whereby each incremental portion comprises less than 50 weight % of the mixture from step I), alternatively 25 weight % of the mixture from step I), and each incremental portion of water continuous emulsion is added successively to the previous after the dispersion of the previous incremental portion of water continuous emulsion, wherein sufficient incremental portions of water continuous emulsion are added to form the bi-modal emulsion.

[0078] The number of incremental portions of the water continuous emulsion and/or water added to the mixture from step I) may vary, but typically at least 2, alternatively, at least 3 incremental portions are added.

[0079] Mixing in step II) can be accomplished by any method known in the art to effect mixing of high viscosity materials and/or effect the formation of an emulsion. The mixing may occur either as a batch, semi-continuous, or continuous process. Any of the mixing methods as described for step I), may be used to effect mixing in step II). Alternatively, mixing in step II) may also occur via those techniques known in the art to provide high shear mixing to effect formation of emulsions. Representative of such high shear mixing techniques include; high speed stirrers, homogenizers, Sonolators®, Microfluidizers®, Ross mixers, Eppenbach colloid mills, Flacktek Speedmixers®, and other similar shear devices.

[0080] Optionally, the emulsion formed in step II) may be further sheared according to an optional step III) to reduce particle size and/or improve long term storage stability. The shearing may occur by any of the mixing techniques discussed above.

[0081] The bi-modal water continuous emulsions prepared by the present process may be characterized by their bi-modal particle size distribution. The particle size may be determined by laser diffraction of the emulsion. Suitable laser diffraction techniques are well known in the art. The particle size is obtained from a particle size distribution (PSD). The PSD can be determined on a volume, surface, length basis. The volume particle size is equal to the diameter of the sphere that has the same volume as a given particle. The term Dv, as used herein, represents the average volume particle size of the dispersed particles. Dv 50 is the particle size measured in volume corresponding to 50% of the cumulative particle population. In other words if Dv 50 = 10 μιη, 50% of the particle have an average volume particle size below 10 μιη and 50% of the particle have a volume average particle size above 10 μιη. Dv 90 is the particle size measured in volume corresponding to 90% of the cumulative particle population. Mode 1 is the median of the distribution of one of the dispersed phase particle populations within a bimodal particle size distribution and Mode 2 is the median of the other. [0082] In some instances, it may be necessary to conduct two separate evaluations of particle size, especially when the particle sizes distributions of the resulting bi-modal emulsions exhibit a wide variation in size. In these instances a Malvern-Mastersizer® 2000 may be used to obtain particle size distributions in the range 0.5 to 1000 μιη, while a Microtrac-Nanotrac® may be used to measure particle size distributions in the ranges less than 0.5 μιη.

[0083] The average volume particle size of the dispersed particles in the oil/water emulsions ranges of from 0.001 μιη to 1000 μιη; or of from Ο.ΟΙμιη to 20 μιη; or of from 0.02 μιη to 10 μιη.

[0084] Alternatively, the average volume particle size of each of the unique dispersed phases (that is the first dispersed phase, and the second dispersed phase), may be reported. The average volume particle size of the first dispersed particles in the oil/water emulsions ranges of from 0.1 μιη to 500 μιη; or of from 0.1 μιη to 100 μιη; or of from 0.2 μιη to 30 μιη. The average volume particle size of the second dispersed particles in the oil/water emulsions ranges of from 0.1 μιη to 500 μιη; or of from 0.1 μιη to 100 μιη; or of from 0.2 μιη to 30 μιη.

[0085] While not wishing to be bound by any theory, it is believed particle size distribution of the first dispersed phase results from the emulsification of the hydrophobic oil, while particle size distribution of the second dispersed phase results from the particles originating from the water continuous emulsion used in the present process. However, there may be certain instances where the two overlap sufficiently that a bi-modal distribution is not observable using the particle size determination techniques described above.

[0086] The bimodal particle size distribution may also be observed using optical microscopy techniques.

[0087] In some instances, the bi-modal emulsions may be considered as a "high solids" emulsion, wherein the bi-modal emulsion contains at least 75% by weight of components (A) and (B), alternatively the bi-modal emulsion contains at least 80% by weight of components (A) and (B), alternatively the bi-modal emulsion contains at least 85% by weight of components (A) and (B), alternatively the bi-modal emulsion contains at least 90% by weight of components (A) and (B) .

[0088] The "high solids" bi-modal emulsion may remain pourable. Thus, the bi-modal emulsions may have a viscosity less than 600,000 mPa.s (10 ^~3 Pa.s), alternatively less than 200,000 mPa.s (10 ^~3 Pa.s), or alternatively less than 100,000 mPa.s (10 ^~3 Pa.s), as measured at 25°C. [0089] The total surfactant concentration in the bi-modal emulsion is less than 4.0 weight , alternatively less than 1.0 weight , or alternatively less than 0.2 weight .

The bi-modal silicone emulsions produced by the present process contains less than 1.0 weight % cyclosiloxanes, alternatively contains less than 0.5 weight % cyclosiloxanes, alternatively contains less than 0.1 weight % cyclosiloxanes.

[0166] INSTRON procedures are standard, recognized, and industrially acceptable protocols, see for example, US Patents 5,389,364 (February 14, 1995), 5,409,695 (April 25, 1995), 5,419,627 (May 30, 1995), and 5,504,149 (April 2, 1996).

[0167] INSTRON COMBING is an industry recognized test for determining hair conditioning obtained from hair compositions, by the ease of wet combing and the ease of dry combing. The test employs an INSTRON strain gauge, which is equipped to measure the force required to comb the hair. The conditioning performance is based on the ability of a particular hair treatment formulation, such as a shampoo or a hair conditioner, to reduce the force required to comb the hair with the INSTRON strain gauge. The force is reported as an Average Combing Load (ACL). The lower the number of the ACL value, the better is the conditioning effect imparted by the formulation being tested. Typically, ACL baselines are initially established using untreated tresses that have only been washed with a sodium lauryl sulfate solution. The effectiveness of a treatment can then be expressed as an ACL of the treated tress or percent reduction in ACL, calculated using the relationship: (untreated hair ACL -treated hair ACL) x 100 divided by the untreated hair ACL.

[0168] Slightly bleached European human hair from DeMeo Brothers was used for testing the compositions prepared herein. Each tress weighed about 2.0 grams. Each tress was rinsed for 15 seconds under a stream of 40 °C tap water. Using a pipette, 1.0 gram of a solution containing nine percent of sodium lauryl sulfate was applied and lathered through the tress for 30 seconds. The tress was rinsed for 30 seconds under running water. Excess water was removed from the tress by passing the tress between the index and middle fingers of the hand. The tresses were placed on a tray covered with paper towels and dried overnight. Each tress was hand combed three times with the narrow teeth of an ACE ® comb, and evaluated using INSTRON WET and INSTRON DRY COMBING procedures.

[0169] For tests involving shampoo compositions, hair tresses are rinsed with tap water for 30 seconds at 40°C. The test composition is applied to the tress in the amount of 0.8 gram, and the tress is stroked for 30 seconds. The tress is rinsed for 30 seconds under tap water at 40°C. Excess water is removed by pulling the tress through the index and middle fingers of the hand. The tresses are allowed to dry separately on a paper towel overnight at room temperature. The tresses are combed once before performing an INSTRON study.

[0170] According to the INSTRON WET COMBING method, hair is first wetted by dipping it into distilled water, and then the hair is detangled by combing the tress three times. The tress is then retangled by dipping in distilled water three times. Excess water is removed by passing the tress through the index and middle fingers of the hand twice. The tress is placed on a hanger and

INSTRON combed. Retangling and INSTRON combing are repeated until all data points are collected. An average combing force of three tresses is measured for each treatment.

[0171] According to the INSTRON DRY COMBING method, hair is detangled by combing the tress 3 times. Then hair is retangled by swirling the tress clockwise 3 times and swirling it counter clockwise 3 times. The tress is then placed on a hanger and INSTRON combed.

Retangle and Instron combing are repeated until all data points are collected. An average combing force for three tresses is measured for each treatment.

DAC-150 SpeedMixer® and the cup was spun at maximum speed (3450 RPM) for 30 seconds. The cup was opened and the walls of the cup were scraped with a spatula and the cup was spun again at maximum speed for 30 seconds. 5g of emulsion (B) was weighed into the cup and the cup was spun for 30 seconds at approximately 2500 RPM. 15.7g of emulsion (B) was added and the cup was again spun for 30 seconds at approximately 2500 RPM. The resulting emulsion (El) consisted of an aqueous oil-in-water (o/w) emulsion of silicone polymer having a total silicone content of approximately 81.05 percent. On a dry basis, this emulsion (El) contained approximately 77 percent 100,000 mPa.s dimethicone as large particles and 23 percent dimethiconol as smaller particles. Particle size of the emulsion (El) was determined using a

Malvern Mastersizer®. The particle size curve showed two distinct peaks, one centred at 6.5μιη and another that was centred at 35μιη. Particle size as calculated by the instrument was as follows: Dv50 = 8.68μιη, Dv90 = 19.82μιη, Mode 1 = 0.73 μιη, Mode 2 = 11.81 μιη.

[0180] Shampoos preparation (Table 2): deionized water was added to the mixing vessel. In order to keep the active silicone loading constant throughout testing, it was necessary to adjust the water level added depending on the percent active silicone in the various emulsions used. With moderate agitation, the polyquaternium-10 was dispersed until fully dissolved and sodium lauryl ether sulfate added. This was then heated to 75°C and the PEG-150 pentaerythrityl tetrastearate was added with continual mixing. Heat was decreased to 40°C and cocamide DEA and cocamidopropyl betaine were added. When completely incorporated, silicone emulsion was added to the base shampoo. The shampoo was mixed for 5-10 minutes and then DMDM hydantoin was added. The water loss was compensated for (to 100%wt total) and the formulation was mixed for an additional 5 minutes. The final pH of the shampoo formulations were ranging of from 5.5 to 6.0.

[0181] The results of INSTRON WET COMBING and DRY COMBING using shampoos from Table 2 were also shown in Table 2.

[0182] INSTRON WET COMBING: The results show that all Example shampoos 1 to 4 containing the bi-modal Emulsions 3 to 6 respectively, provided a reduction in wet combing force. The Example shampoos 1, 3 and 4 were similar in performance to the respective Comparative shampoos 1, 3 and 4, meaning they are capable of improving the wet conditioning properties of hair.

[0183] INSTRON DRY COMBING: The results show that all Example shampoos 1 to 4 containing the bi-modal Emulsions 3 to 6 respectively, provided a reduction in dry combing force. The Example shampoos 1 to 4 were similar in performance to the respective Comparative shampoos 1 to 4, meaning they are capable of improving the dry conditioning properties of hair.

[0184] Wet feel/slipperiness, dry feel/slipperiness, smoothness, shine and volume of the tresses treated with the Example shampoos 1 to 4 were similar to the tresses treated with the respective Comparative shampoos 1 to 4.

[0194] The resulting emulsion (E10) consisted of an aqueous oil-in-water (o/w) emulsion of silicone polymer having a total silicone content of approximately 81.05 wt. On a dry basis, this emulsion (E10) contained approximately 68.6 percent 80 Pa.s dimethiconol as large particles and 31.4 wt bis-diisopropanolamino-PG-propyl dimethicone/bis-isobutyl PEG- 14 copolymer as smaller particles. Particle size of the emulsion (E10) was determined using a Malvern Mastersizer®. Particle size as calculated by the instrument was as follows: Dv50 = 7.041μιη, Dv90 = 14.265μιη, Mode 1 = 1.045 μιη, Mode 2 = 7.665 μιη.

Emulsion 11

[0195] Emulsification of (A) as dimethiconol 80 Pa.s, with an (micro)emulsion (B) of silicone quaternium-16 and undeceth-11 and butyloctanol and undeceth-5 (B - 22 % silicone - Dv50 = 0.0463 μιη): 5.00g of emulsion (B) and 28.20g of dimethiconol were weighed into a cup. lO.OOg of glass beads were added to provide additional shear. The cup was closed and placed inside a DAC-150 SpeedMixer® and the cup was spun at maximum speed (3450 RPM) for 30 seconds.

The Dv50 of the initial emulsion (B), as measured by a Microtrac Nanotrac 150, is of 0.0463 μιη. These smaller particles cannot effectively be measured when the larger particles are present, because of the optical effect of the larger particles on the measurement apparatus. Nevertheless, evidence of the presence of such smaller particles is made by the flowable character of Emulsion 11 which would not be the case if only large particles were present at such high silicone content.

Emulsion 12

[0197] Emulsification of (A) as dimethiconol 80 Pa.s, with a (micro)emulsion (B) of amodimethicone and) CI 1-15 pareth-7 and) laureth-9 and glycerin and trideceth-12 (B - 20 % silicone - Dv50 = 0.0146 μηι): 2.50g of emulsion (B) and 27.74g of dimethiconol were weighed into a cup. lO.OOg of glass beads were added to provide additional shear.

The Dv50 of the initial emulsion (B), as measured by a Microtrac Nanotrac 150, is of 0.0146 μιη. These smaller particles cannot effectively be measured when the larger particles are present, because of the optical effect of the larger particles on the measurement apparatus. Nevertheless, evidence of the presence of such smaller particles is made by the flowable character of Emulsion 12 which would not be the case if only large particles were present at such high silicone content.

Emulsion 13

[0199] Emulsification of (A) as a mixture of dimethicone 600 Pa.s and amodimethicone, with an emulsion (B) divinyldimethicone/dimethicone copolymer and C12-13 pareth-23 and C12-13 pareth-3 (B - 60 % silicone): 3.60g of emulsion (B), 39.84g of dimethicone 600 Pa.s, 9.96g of amodimethicone and 1.20g of water were weighed into a cup.

[0200] The resulting emulsion (E13) consisted of an aqueous oil-in-water (o/w) emulsion of silicone polymer having a total silicone content of approximately 86.81 wt. On a dry basis, this emulsion (E13) contained approximately 64.8 wt dimethicone, 16.2 wt amodimethicone, and 19.0 wt divinyldimethicone/dimethicone copolymer.
