Title: Cosmetic product comprising oil discontinuous phase and method of use thereof

Description:
FIELD OF THE INVENTION 
     The present invention is directed to a cosmetic product comprising a cosmetic composition comprising an aqueous phase and an initial oil phase, wherein the cosmetic composition is contained in a container; wherein the product also comprises an indicia for a user to shake the container; wherein, by the shake, the composition is designed to break the initial oil phase into oil discontinuous phases dispersed in the aqueous phase, wherein the oil discontinuous phase has a particle size of from about 0.01 mm to about 20 mm, wherein the oil discontinuous phase is dispersed for at least 24 hours. The cosmetic product of the present invention provides prolonged dispersion of the dispersed oil phases. The present invention is also directed a method of use thereof. 
     BACKGROUND OF THE INVENTION 
     Mammalian keratinous tissue, particularly human skin, is subjected to a variety of insults by both extrinsic and intrinsic factors. Such extrinsic factors include ultraviolet radiation, environmental pollution, wind, heat, infrared radiation, low humidity, harsh surfactants, abrasives, etc. Intrinsic factors, on the other hand, include chronological aging and other biochemical changes from within the skin. Whether extrinsic or intrinsic, these factors result in visible signs of skin damage. Typical skin damages in aging or damaged skin include fine lines, wrinkling, hyperpigmentation, sallowness, sagging, dark under-eye circles, puffy eyes, enlarged pores, diminished rate of turnover, and abnormal desquamation or exfoliation. Additional damage incurred as a result of both external and internal factors includes visible dead skin i.e., flaking, scaling, dryness, and roughness. 
     Currently, there are a number of personal care products that are available to consumers, which are directed toward improving the health and physical appearance of keratinous tissues such as the skin, hair, and nails. The majority of these products are directed to delaying, minimizing or even eliminating skin wrinkling, spots, and other histological changes typically associated with the aging of skin or environmental damage to human skin. Consumers prefer topically applied products since they are not only effective, but also safe and pleasant to use. 
     For example, there are some dual phase products which contain both oil and water phases in one bottle wherein the oil phase usually floating on the surface of a water phase, and which are recommended for consumers to shake the bottle before use to make the oil phase dispersed in the water phase. Some of such oil dispersions are visible. However, such oil phase dispersions can be observed usually for only a few hours. There exists a need for such dual phase products which can sustain the dispersed oil phase for a longer period of time. 
     On the other hand, in view of sustained dispersion and/or visible dispersion of oil phases in water phases, the uses of polymer encapsulations and/or oil-absorbing porous particulates are known. However, in order to contain a certain amount of the oils in the composition, relatively higher amount of such polymer encapsulations and/or oil-absorbing porous particulates need to be used. There also exists a need for oil dispersion to be sustained for a longer period of time and/or to be visible, without the uses of polymer encapsulations and/or oil-absorbing porous particulates. 
     Based on the foregoing, there is a need for a cosmetic product providing prolonged dispersion of the dispersed oil phases, especially providing prolonged dispersion of the visible dispersed oil phases, especially without the use of polymeric encapsulation and/or oil-absorbing porous particulates for dispersions. 
     SUMMARY OF THE INVENTION 
     A method of use of a cosmetic product, wherein the cosmetic product comprises a cosmetic composition comprising an aqueous phase and an initial oil phase, wherein the cosmetic composition is contained in a container; wherein the method comprises a step to shake the container, to break the initial oil phase into oil discontinuous phases dispersed in the aqueous phase, wherein the oil discontinuous phase has a particle size of from about 0.01 mm to about 20 mm, and wherein the oil discontinuous phase is dispersed for at least 24 hours. The method of the present invention provides prolonged dispersion of the dispersed oil phases.

Elasticity Values G′ Max. And G″
   
               

     The aqueous phase can have a certain “G′ max.” value, depending on the type of hydrophilic thickener contained in the aqueous phase, and also depending on the density difference between the aqueous phase and the oil phases. The details of such preferred “G′ max.” values are shown in Table 1, in view of retain the oil dispersion for longer time. 
     The elasticity values G′ max. and G″ are measured by using the exact composition of the aqueous phase containing all ingredients used in the aqueous phase. Measurement method and conditions are as follows, and the same method and conditions are applied for the measurement of Cross Point (CP) described below: 
     Method: Oscillation Stress Sweep Method 
     Instrument: Discovery HR-2 Rheometer (TA Instrument) 
     Geometry: 40 mm 2.004° cone plate, Peltier plate Aluminium
 
Geometry Gap setting: Trim gap offset is 50 μm, Truncation gap is 48 μm
 
     Conditioning-Sample (Step 1) 
     Temperature set: 25° C. 
     Oscillation-Amplitude (Step 2) 
     Temperature Set: 25° C. 
     Test Parameter: Frequency 1 Hz, Logarithmic sweep, Stress 1.0 up to 100 Pa, Points per decade are at least 10. 
     Cross Point (CP) 
     Cross point is where G′ and G″ cross. As shown in Table 1, when the aqueous phase contains hydrophilic thickener thickener  w/o  associating ability to oil, and especially when the aqueous phase is free of hydrophilic thicker  w/  associating ability to oil, it is preferred that the aqueous phase has such cross point, in view of retaining the oil dispersion for longer time. 
     Density Difference 
     The oil phases and the aqueous phase can have a certain difference in their densities as shown in Table 1, in view of making the oil discontinuous phase dispersed for longer time. 
     The density of the oil phases is measured by using the exact composition of the oil phases containing all ingredients used in the oil phases, but excluding solid particulates if used in the oil phases. 
     The density of the aqueous phase is measured by using the exact composition of the aqueous phase containing all ingredients used in the aqueous phase, but excluding those dispersed and those which do not form continuous phase with an aqueous carrier if such ingredients are used in the aqueous phase. 
     The densities are measured at 20-25° C. 
     Viscosity of the Oil Phases 
     The initial oil phase and the dispersed oil discontinuous phase can have the following viscosities: 
     When the oil phases are newtonian, from about 1 cps to about 20,000 cps, alternatively from about 1 cps to about 10,000 cps; and 
     When the oil phases are non-newtonian, from about 1 cps to about 300,000 cps, alternatively from about 1 cps to about 200,000 cps., alternatively from about 2 cps to about 100,000 cps. 
     This viscosity, together with the viscosity of the aqueous phase helps the initial oil phase to be dispersed as the dispersed oil discontinuous phase upon shake. 
     The viscosities of the initial oil phase and the dispersed oil discontinuous phase are measured by using the exact composition of these oil phases containing all ingredients used in these oil phases. 
     Measurement method and conditions are as follows: 
     At room temperature, Brookfield RV Viscometer, T bar, (T-A bar for low viscosity, T-E for high viscosity), spindle speed=5 rpm for both newtonian and non-newtonian oil phases. 
     Viscosity of the Aqueous Phase 
     The aqueous phase can have a viscosity of from about 100 cps to about 50000 cps, 
     alternatively from about 100 cps to about 30000 cps 
     The viscosity of the aqueous phase is measured by using the exact composition of the aqueous phase containing all ingredients used in the aqueous phase. 
     Measurement method and conditions are as follows: 
     At room temperature, Brookfield RV Viscometer, T bar, (T-A bar for low viscosity, T-E for high viscosity), spindle speed=5 rpm 
     Other Ingredients 
     Skin Conditioning Agent

For example, a “C12 alcohol” refers to an alcohol that has 12 carbon atoms in its chain (i.e., dodecanol). 
     The fatty alcohol may be included in the compositions herein at 0.0001% to 15% (e.g., 0.0002% to 10%, 0.001% to 15%, 0.025% to 10%, 0.05% to 7%, 0.05% to 5%, or even 0.1% to 3%) by weight of the composition. 
     Whitening Agents 
     The present compositions may contain a whitening agent. The whitening agent useful herein refers to active ingredients that not only alter the appearance of the skin, but further improve hyperpigmentation as compared to pre-treatment. Useful whitening agents useful herein include ascorbic acid compounds, vitamin B 3 compounds, azelaic acid, butyl hydroxy anisole, gallic acid and its derivatives, hydroquinoine, kojic acid, arbutin, mulberry extract, tetrahydrocurcumin, and mixtures thereof. Use of combinations of whitening agents is also believed to be advantageous in that they may provide whitening benefit through different mechanisms. 
     When used, the compositions can contain from about 0.1% to about 10%, alternatively from about 0.2% to about 5%, by weight of the composition, of a whitening agent.

     In some examples, the composition can be substantially free of emulsifiers, alternatively the composition is free of emulsifiers, i.e. contains 0% of emulsifiers. 
     Other Optional Ingredients. 
     Compositions herein may include one or more optional ingredients known for use in topical cosmetic compositions, provided that the optional components do not unacceptably alter the desired benefits of the composition. In some instances, it may be desirable to select cosmetic actives that function via different biological pathways so that the actives do not interfere with one another. When the composition is in the form of an emulsion, the additional ingredients should not introduce instability into the emulsion (e.g., syneresis). For example, it may be desirable to select optional ingredients that do not form complexes with other ingredients in the composition, especially pH sensitive ingredients like vitamin B3 compounds, salicylates and peptides. 
     The additional ingredients should be suitable for use in contact with human skin tissue without undue toxicity, incompatibility, instability, allergic response, and the like. The optional components, when present, may be included at an amount of about 0.001% to 50% (e.g., 0.01% to 40%, 0.1% to 30%, 0.5% to 20%, or 1% to 10%), by weight of the composition.

In some instances, the sucrose ester may be a blend of sucrose laurate and sucrose dilaurate, wherein sucrose laurate is present at 50% to 80%, by weight of the sucrose ester, and the sucrose dilaurate is present at 20% to 45%, by weight of the sucrose ester. Alternatively, the sucrose ester may be a blend of sucrose laurate, sucrose dilaurate and sucrose trilaurate, wherein the sucrose dilaurate is present at 35% or more, by weight of the sucrose ester. A particularly suitable example of a sucrose ester for use herein is Sucrose Dilaurate BC10034 available from BASF. 
     Method of Use of the Cosmetic Composition 
     The method of use herein includes identifying a target portion of skin on a person in need of treatment and applying the composition to the target portion of skin over the course of a treatment period. The target portion of skin may be on a facial skin surface such as the forehead, perioral, chin, periorbital, nose, and/or cheek) or another part of the body (e.g., hands, arms, legs, back, chest). The person in need of treatment is one whose skin exhibits signs of oxidative stress, such as fine lines, wrinkles, hyperpigmentation, uneven skin tone, and/or other visible skin features typically associated with aging. In some instances, the target portion of skin may not exhibit a visible sign of skin aging, but a user (e.g., a relatively young user) may still wish to target such an area of skin, if it is one that typically develops such issues as a person age. In this way, the present method may be used as a preventative measure to delay the onset of visible signs of skin aging. 
     The composition may be applied to a target portion of skin and, if desired, to the surrounding skin at least once a day, twice a day, or on a more frequent daily basis, during a treatment period. When applied twice daily, the first and second applications are separated by at least 1 to 12 hours. Typically, the composition is applied in the morning and/or in the evening before bed. The treatment period may last for at least 1 week (e.g., about 2 weeks, 4 weeks, 8 weeks, or even 12 weeks). In some instances, the treatment period will extend over multiple months (i.e., 3-12 months). In some instances, the composition may be applied most days of the week (e.g., at least 4, 5 or 6 days a week), at least once a day or even twice a day during a treatment period of at least 2 weeks, 4 weeks, 8 weeks, or 12 weeks. 
     The step of applying the composition may be accomplished by localized application. In reference to application of the composition, the terms “localized”, “local”, or “locally” mean that the composition is delivered to the targeted area (e.g., a wrinkle or line) while minimizing delivery to skin surfaces where treatment is not desired. The composition may be applied and lightly massaged into an area of skin. The form of the composition or the dermatologically acceptable carrier should be selected to facilitate localized application. While certain embodiments herein contemplate applying a composition locally to an area, it will be appreciated that compositions herein can be applied broadly to one or more skin surfaces. In certain embodiments, the compositions herein may be used as part of a multi-step beauty regimen, wherein the present composition may be applied before and/or after one or more other compositions.

     Ex. 1 through Ex. 5 are skin care cosmetic compositions for the method described herein. CEx. i is a skin care cosmetic composition provided as a comparative example. 
     The compositions are contained in fully transparent bottles, on which an indicia meaning “shake the container before use” are printed by words. The containers with the cosmetic compositions are shaken before use. As shown in the above tables, the composition can provide prolonged dispersion of the dispersed oil phases. 
     The dimensions and values disclosed herein are not to be understood as being strictly limited to the exact numerical values recited. Instead, unless otherwise specified, each such dimension is intended to mean both the recited value and a functionally equivalent range surrounding that value. For example, a dimension disclosed as “40 mm” is intended to mean “about 40 mm”.
