Patent Application
20160074315
The presently described subject matter relates to topical cosmetic or dermatological compositions comprising plant extracts. These compositions are used for topical cosmetic applications, particularly to treat undesired skin pigmentation.
Topical cosmetic skin lightening compositions that are safe and effective are particularly desirable for treating undesirable skin pigmentation, including for example, regional hyperpigmentation caused by melanocytic hyperactivity such as idiopathic melasma occurring during pregnancy (mask of pregnancy or chloasma) or secondary to estrogen-progesterone contraception; local hyperpigmentation caused by benign melanocytic hyperactivity and proliferation such as lentigo senilis, known as liver spots; accidental hyperpigmentation such as post-lesional photosensitization and scarring; skin ageing (for example lentigines seniles); and certain forms of leukoderma such as vitiligo where, if the injured skin cannot be repigmented, the residual zones of normal skin are lightened or depigmented to impart a homogeneous color to the entire skin.
Several active ingredients and preparations that lighten skin, i.e., counteract skin pigmentation, are currently known. These products that are currently used contain hydroquinone, but such products have recently been deemed unacceptable for toxicological reasons. In fact, RDC 215 forbids the use of hydroquinone in cosmetic products after December, 2007.
U.S. Published Patent Application No. 2008/0050459 describes a cosmetic composition comprising an extract of Phyllanthus Embilica, an extract of Bellis Perrenis, an extract of Glycyrrhiza Glabra, and requiring at least one oligopeptide to achieve its cosmetic effect for the combined cosmetic treatment of fine lines and wrinkles, and/or skin brightening. Suitable oligopeptides are described as those having a suitable molecular weight so that they are able to act as carriers of Phyllanthus Embilica extract and penetrate skin to maximize the efficacy. The only oligopeptides described in the publication for achieving the cosmetic composition are oligopeptide-4 (pro-collagen oligopeptide) and oligopeptide-5 (pro-elastin oligopeptide).
There remains a need in the art for improved topical cosmetic compositions containing agents that safely and effectively lighten skin.

The topical cosmetic compositions may optionally further comprise one or more optical brighteners. Optical brighteners are described in Fluorescent Whitening Agent, Encyclopedia of Chemical Technology, Kirk-Othmer, Vol. 11, pp. 227-241, 4th edition, 1994, Wiley, which is hereby incorporated by reference herein in its entirety. Optical brighteners can be defined more particularly as compounds which absorb in the UVA range between 300 and 390 nm and re-emit essentially between 400 and 525 nm.

In an embodiment, the present subject matter relates to a method of lightening skin pigmentation in a subject, comprising topically administering to skin of a subject in need thereof, a therapeutically effective amount of the topical cosmetic composition in accordance with the subject matter described herein.
In another embodiment, the present subject matter relates to a method of treating a skin disorder or condition in a subject, comprising topically administering to skin of a subject in need thereof, a therapeutically effective amount of the topical cosmetic composition in accordance with the subject matter described herein. The skin disorder or condition can be a disorder or condition associated with undesirable skin pigmentation.
In another embodiment, the present subject matter relates to a method of lightening skin pigmentation in a subject or treating a skin disorder or condition in a subject, comprising topically administering for at least once per day for at least three days, for at least five days, for at least seven days, for at least ten days, or for at least fourteen days, to skin of a subject in need thereof, a therapeutically effective amount of the topical cosmetic composition in accordance with the subject matter described herein. In this regard, after three days, five days, seven days, ten days, or fourteen days, respectively, of administration of the present topical compositions the skin is visibly altered.
In an embodiment, the present subject matter relates to a method of lightening skin pigmentation in a subject or treating a skin disorder or condition in a subject, comprising topically administering for at least once per day for at least three weeks to skin of a subject in need thereof, a therapeutically effective amount of the topical cosmetic composition in accordance with the subject matter described herein, wherein after three weeks the skin is visibly lightened.
The present topical cosmetic compositions are effective in treating a variety of skin disorders or conditions characterized by undesirable skin pigmentation. Non-limiting examples of such disorders and/or conditions can include regional hyperpigmentation caused by melanocytic hyperactivity such as idiopathic melasma occurring during pregnancy (mask of pregnancy or chloasma) or secondary to estrogen-progesterone contraception; local hyperpigmentation caused by benign melanocytic hyperactivity and proliferation such as lentigo senilis, known as liver spots; accidental hyperpigmentation such as post-lesional photosensitization and scarring; freckles; malpigmentation; and certain forms of leukoderma such as vitiligo where, if the injured skin cannot be repigmented, the residual zones of normal skin are lightened or depigmented to impart a homogeneous color to the entire skin. Skin can be treated according to the presently described methods for purely cosmetic lightening of areas, for example, large areas, of skin whose pigmentation, although undesired, is adequate for the individual skin type. In an embodiment, the skin disorder or condition to be treated according to the present methods is undesired skin pigmentation. The administration of the present topical cosmetic composition to areas of the skin that contain undesired pigmentation, lightens those areas. Accordingly, the present methods lighten areas of the skin to which the present topical cosmetic compositions are administered.
Suitable skin areas for treatment and/or lightening in accordance with the subject matter described herein can include thin skin areas including for example areas of skin on the face, neck, and/or hands. The present compositions and methods as described herein are suitable for use in both men and women, and are suitable for use on all skin types including dry skin types, normal skin types, and greasy skin types.
In a further embodiment, the present subject matter relates to a method of treating a skin disorder or condition in a subject, or to a method of lightening skin pigmentation in a subject, wherein topically administering to skin comprises administering at least once per day or at least twice per day for a period of at least two weeks, at least 3 weeks, or at least 4 weeks, wherein skin pigmentation is lightened. Administering at least once per day can comprise administering once in the morning or in the evening. Administering at least twice per day can comprise administering once in the morning and once in the evening.
Various formulations of the present topical cosmetic compositions in accordance with the presently described subject matter can be readily produced by the skilled artisan according to known methods of producing such formulations including for example, a cream, a gel, a serum, a lotion, or other formulation described herein, without undue experimentation.
A process for producing a cream or emulsion formulation can comprise separately producing an aqueous phase and an oil phase, adding the oil phase to the aqueous phase, for example with mixing and/or homogenization (with high shear), to an emulsion. After the emulsion is produced, one or more of the following components can be optionally added thereto, for example, in the following order, to produce the final emulsion or cream: one or more skin lightening actives; one or more pH adjusters; one or more emollients; one or more skin lightening actives; one or more sunscreen actives; one or more thickening agents; one or more antioxidants; and one or more fragrances. Prior to forming the emulsion, the aqueous phase and the oil phase can be separately heated to a temperature of from about 70° C. to about 99° C.; from about 75° C. to about 95° C.; from about 80° C. to about 90° C.; or about 85° C. After heating the oil phase can be slowly added to the aqueous phase, for example, with mixing and high shear homogenization. The resultant emulsion can then be cooled while maintaining mixing and high shear homogenization, for example, to a temperature of from about 47° C. to about 27° C.; from about 42° C. to about 30° C.; from about 39° C. to about 35° C.; or about 37° C. Thereafter, one or more of the above-described optional components can then be added to the cooled emulsion, for example, with mixing and/or high shear homogenization. The produced emulsion or cream can have a pH of from about 4.5 to 6.5 and/or a viscosity of from about 5,000 cP to about 15,000 cP and/or a density of from about 1.01 to about 1.06.
Further contemplated as within the scope of the present subject matter are topical cosmetic compositions produced according to the above-described processes. If produced according to these processes, these compositions exhibit chemical and physical stability suitable for topical administration.
The topical cosmetic compositions produced according to these processes can be placed in a suitable containment vessel comprising a product contact surface composed of a material selected from the group consisting of glass, plastic, steel, stainless steel, aluminum, Teflon, polymeric structure, ceramic structure, alloys, and mixtures thereof. These containment vessels are used to facilitate manufacturing, handling, processing, packaging, storage, and administration of said topical cosmetic composition. Suitable containment vessels in this regard can be selected from the group consisting of plastic tubes, bottles, metal tubes, and any combination thereof.
To be effective, the route of administration for topical cosmetic compositions used in the present methods must readily affect the target skin areas. Effective results in most cases are achieved by topical application of a thin layer over the affected area, or the area where one seeks to achieve the desired effect. Effective results can be achieved with application rates from one application every two or three days to four or more applications per day.
Appropriate dosage levels for the active agents contemplated in the present topical cosmetic compositions and methods are well known to those of ordinary skill in the art and are selected to maximize the treatment of the above skin conditions. Dosage levels on the order of about 0.001 mg to about 5,000 mg per kilogram body weight of the skin lightening active components are known to be useful in the treatment of the diseases, disorders, and conditions contemplated herein. Typically, this effective amount of the skin lightening active components will generally comprise from about 0.001 mg to about 100 mg per kilogram of patient body weight per day. Moreover, it will be understood that this dosage of ingredients can be administered in a single or multiple dosage units to provide the desired therapeutic effect.
If desired, other therapeutic agents can be employed in conjunction with those provided in the above-described compositions. The amount of active ingredients that may be combined with the carrier materials to produce a single dosage form will vary depending upon the host treated, the nature of the disease, disorder, or condition, and the nature of the active ingredients.
The present compositions may be given in a single dose or multiple doses daily. In an embodiment, the present topical cosmetic compositions are given from one to four times daily. Starting with a low dose once or twice daily and slowly working up to higher doses if needed is a strategy. The amount of active ingredients that may be combined with the carrier materials to produce a single dosage form will vary depending upon the host treated, the nature of the disease, disorder, or condition, and the nature of the active ingredients. In an embodiment, the topical cosmetic compositions may be topically applied once or multiple times per day. In an embodiment, the present topical cosmetic compositions are topically applied from one to four times daily. For example, starting with once daily and progressing to more frequent applications, if needed, is one strategy.
In an embodiment, the present topical cosmetic compositions are topically applied from one to four times daily, for example, in the morning, at noon, in the afternoon, and/or in the evening.
In an embodiment, the topical cosmetic compositions as described herein can be administered once or multiple times per day for a period of time of at least one week, for a period of at least two weeks, for a period of at least four weeks, or for a period of at least eight weeks. The topical cosmetic compositions can be administered once or multiple times per day for a period of time of up to one year, of up to six months, of up to three months, or of up to two months.
It is understood, however, that a specific dose level for any particular patient will vary depending upon a variety of factors, including the activity of the specific active agent; the age, body weight, general health, sex and diet of the patient; the time of administration; the rate of excretion; possible drug combinations; the severity of the particular condition being treated; and the form of administration. One of ordinary skill in the art would appreciate the variability of such factors and would be able to establish specific dose levels using no more than routine experimentation.
Pharmacokinetic parameters such as bioavailability, absorption rate constant, apparent volume of distribution, unbound fraction, total clearance, fraction excreted unchanged, first-pass metabolism, elimination rate constant, half-life, and mean residence time are well known in the art.
The optimal cosmetic formulations can be determined by one skilled in the art depending upon considerations such as the particular ingredients and the desired dosage. See, for example, Remington's Pharmaceutical Sciences, 18th ed. (1990, Mack Publishing Co., Easton, Pa. 18042), pp. 1435-1712, and “Harry's Cosmeticology”, 8th ed. (2000, Chemical Publishing Co., Inc., New York, N.Y. 10016), the disclosure of each of which is hereby incorporated by reference herein in its entirety. Such formulations may influence the physical state, stability, rate of in vivo release, and rate of in vivo clearance.
In an embodiment, the present topical cosmetic composition in accordance with the subject matter described herein may be a gel cream packaged in, for example, a tube, or a serum packaged in, for example, a non-aerosol non-foaming pump container or bottle, wherein the amount of the composition contained in the container can be in the range of from about 10 gm to about 60 gm, between about 20 gm and about 50 gm, or about 30 gm, or about 40 gm.
Single dosage kits and packages containing once per day amount of composition may be prepared. Single dose, unit dose, and once-daily disposable containers of the present compositions are contemplated as within the scope of the present subject matter.
The present topical cosmetic compositions in accordance with the subject matter described herein may be formulated for storage in a substantially non-reactive laminated package to enhance stability of the package. This method of storage provides enhanced package stability in comparison with other, paper-based packages.
The amount of composition per single packet may range be from about 0.1 ml to about 20.0 ml, between about 0.5 and about 5.0 ml, or between about 1 and about 3 ml.
In particular, the ability to formulate compositions capable of long term storage, without pre-mixing or compounding requirements prior to application is also contemplated. Specifically, the present compositions remain unexpectedly stable in storage for periods including between about 3 months and about 3 years, about 3 months and about 2.5 years, between about 3 months and about 2 years, between about 3 months and about 20 months, and alternately any time period between about 6 months and about 18 months.
In an embodiment, the presently described topical cosmetic formulation in accordance with the subject matter described herein remains stable for at least three years at a temperature of less than 30° C. In an embodiment, the presently described topical cosmetic formulation remains stable for at least two years at a temperature of less than or equal to 30° C. In an embodiment, the presently described topical cosmetic formulation remains stable for at least two years at a temperature of less than or equal to 25° C.
The following examples are illustrative of the present topical cosmetic compositions and are not intended to be limitations thereon. Any polymer molecular weights are mean average molecular weights. All percentages are based on the percent by weight of the final delivery system or formulation prepared unless otherwise indicated and all totals equal 100% by weight.
The following example illustrates the clarifying efficacy of the present topical cosmetic composition as compared to a 2% hydroquinone composition, determined through colorimetry instrumental methodology.
In a monocentric, double-blind, comparative clinical trial over a period of six (6) weeks, the clarifying efficacy of each of two topical products was evaluated in the previously pigmented skin of 10 (ten) volunteers. Dermatological evaluations were performed at the beginning and the end of the study Skin color was measured by colorimetry, together with the photographic documentation, at T0, T07, T14, and T21. UVB pigmentation was induced in the previously pigmented skin of the volunteers through the use of a light emitting source, i.e., the solar simulator with Xenon arc light 601/300 W, produced by Solar Light CO.
A Minolta Chroma Meter CR400 through a standard color system CIE (The Commission Internacional de l'Eclairage) was used to determine the skin coloration. The color is expressed by a system of three-dimensional coordinates where the L* axis corresponds to skin luminosity, the a* axis corresponds to green and red colors, and the b* axis corresponds to blue and yellow colors.
The solar simulator with Xenon arc light 601/300 W, produced by Solar Light CO, was used as the light source. This equipment provides continuous light emission in the UVB and UVA spectrum, ranging between 290 and 400 nm. The device includes a set of lenses and filters that absorb or disperse irradiation lower than 320 nm or higher than 400 nm. The irradiation occurs through a set of 6 branches of optic fiber called “ports”, programmed to apply pre-established individual doses of irradiation. Irradiation monitoring was performed using a Dose Controlling System (DCS), which includes a UVB irradiation detector and an electronic monitor. In this study, only three “ports” were used for each application site of the tested compositions.

1. Population Sampling:
Ten (10) volunteers, of both sexes, of ages between 18 and 60 years old, were screened for the performance of the study. The subjects participating had the first four letters of the name and the first letter of the family name, an individual identification number (generated by electronic system) and a protocol number.
2. Inclusion Criteria:
3. Exclusion Criteria
1. Methodological Procedures:
After the initial procedures, the minimum erythematose dose necessary to induce pigmentation in each volunteer, was determined as described below.
a. Calculation of the Minimum Erythematose Dose:
Each volunteer was subjected to a pre-test to evaluate the minimum erythematose dose (MED). A series of six exposures were applied to the unprotected skin of each volunteer, each one of them being 12% higher than the previous one, in geometric progression. The median dose was previously determined according to Fitzpatrick Phototype, shown in Table I below:
After irradiation, the volunteers were dismissed and instructed to return after 24 hours. Exposure data was recorded for each volunteer.
b. Reading:
After irradiation, each volunteer was released and instructed to return within 24 hours, whereby the exposure site was read with the volunteer in a vertical position at a predetermined distance and illumination which was kept constant for each volunteer. The MED was then determined for each volunteer.
The individual Minimum Erythematose Dose (iMED) is defined as the minimum ultraviolet (UV) radiation dose necessary to produce clear and well-defined contour erythema at the exposure site, which was used as a reference during the test stage.
Accordingly, sub-sites not presenting erythema were a required criterion for the test evaluation. If this does not occur, new applications must be performed to determine the iMED.
c. Induction of Pigmentation:
After iMED determination, each test site, located on the back, between the pelvic and scapular waist, laterally to the medial line of the spine, was marked with the volunteer in a horizontal position and using a marker. Three sites indicated for the application of the products were delimited, i.e., Site B, Site E, and Site F. Each site was 35 cm2 (07×05 cm). At each of the delimited sites, irradiation equivalent to 1.5 times the minimum erythematose dose, previously calculated for each volunteer, was applied. This application was repeated twice whereby each site was irradiated a total of three times.
d. Product Application:
After the irradiation, the volunteers were dismissed and instructed to return after 72 hours for photographic documentation and colorimetric evaluation of the sites. Subjects were tested in triplicate with each of Site B, E, and F corresponding to three distinct irradiation areas to provide a total of three test Sites and nine designation areas per subject. After evaluation, 2 mg of each test material was applied to a designated irradiation area of a test Site on each subject once dailyaccording to the sequence below:
Site B: Hydroquinone 2%;
Site E: The present topical cosmetic composition;
Site F: Negative Control: Site with no product application.
In order to optimize the products permeation and avoid product migration, handling or UV exposure, the product application sites were occluded with filter paper, supported by a semi-permeable adhesive tape. The volunteer returned to the clinic for application, readings and evaluations according to Table II below.
e. Colorimetric Evaluation:
The colorimetric evaluation was performed using a CHROMA METER. All measurements were performed three times, the L*a*b* parameters average were recorded for each volunteer. The L* parameter was separately statistically analyzed, as its value decreases.
f. Statistics:
To check if there is a statistically significant difference between the treated and control sites and between the experimental timepoints, the parameter L* was compared. This comparison was made through t-student tests for paired data.
The treatments were evaluated clinically and colorimetrically on day T7, T14 and T21. Site B which contained the positive control (Hydroquinone 2%) had the colorimetric average for each experimental time as shown in

In an experimental model with UV radiation induced pigmentation (melanogenesis) and having no preexisting pigmentary dysfunction, clinical pigmentation will be reduced spontaneously over time, on the treated areas. All locations, including the untreated control, exhibited a significant reduction in pigmentation up to T21 as evaluated using a colorimeter.
Therefore, this experiment was carried out to comparatively evaluate which treatments would cause the quickest and most significant depigmentation. Because all of the treatments were applied simultaneously to each volunteer, the variable of melanization capacity was significantly reduced. Accordingly, depigmentation would occur at the same speed on all of the tested locations, in each volunteer.
Starting from this premise, the lightening effect was clinically observed over time for each location, which has already allowed for a visual evaluation and a comparative analysis.
To improve the accuracy of these observations and to allow for objective, consistent, and reproducible evaluation, the colorimeter was used as a complementary instrumental evaluation, enabling the detection of differences which the human eye cannot detect.
According to the colorimetry, the L* parameter provided by the colorimetric measurement is the index directly related to the skin's luminosity. The higher the value of L* the lighter the evaluated region.
Clinically and colorimetrically evaluating the treatments the progressive depigmentation was expected, as it deals with an experimental melanization phenomenon. The irradiated but untreated control locations, presented a significant colorimetric improvement of L* as from T21, with the hydroquinone; nevertheless, the lightening levels, when compared to the hydroquinone on T07 and T14, were statistically lower.
Still considering the data over time, the results differ in the following manner: Hydroquinone: significantly improves as from T21; The present topical cosmetic composition: significantly improves as from T14, with statistically significant higher lightening levels when compared to the control. Accordingly, the present topical cosmetic composition provided a faster and more significant lightening effect (provides a higher lightening index) as compared to hydroquinone.
The following example illustrates the preparation of a cream in accordance with the presently described subject matter:
