FIELD

The present disclosure relates generally to compositions of different color beads suspended in a clear base.

BACKGROUND

The information provided below is not admitted to be prior art to the present invention, but is provided solely to assist the understanding of the reader.

Compositions using single colored beads suspended in a clear base are known in the cosmetics industry. The single color beads suspended in a clear base provides a visual impact on the shelf but does not provide the depth of color required to enhance or correct the color of the skin.

Colored beads contain various pigments. The type of pigments found in the beads effect the way the beads break when dispensed. Different colored beads have not previously been mixed in a clear gel because dispensing the different colored beads results in broken and . unbroken beads that do not mix evenly.

There is a need in the cosmetics industry to create a composition that corrects and enhances the color of the skin and maintains the visual impact on the shelf for the consumer.

DESCRIPTION

The cosmetic compositions and methods of the present disclosure consist of, or consist essentially of the elements and limitations described herein, as well as any additional or optional ingredients, components, or limitations otherwise useful as found in personal care compositions intended for application to nail coatings. A person skilled in the art will take care to select the optional additional additives and/or the amount thereof such that the advantageous properties of the composition according to the invention are not, or are not substantially, adversely affected by the envisaged addition. These substances may be selected variously by the person skilled in the art in order to prepare a composition which has the desired properties, for example, consistency or texture. These additives may be present in the composition in a proportion from 0% to 99% (such as from 0.01% to 90%) relative to the total weight of the composition and further such as from 0.1% to 50% (if present).

The present disclosure relates generally to a composition having at least two different color beads suspended in a clear base, the composition is dispensed from a non-aerosol container having a screen through which the beads pass and are broken, sheared, blended and dispensed as a uniform colored composition having a color evenness related to a specific color. The technical challenge presented was to blend different color beads containing different pigments in a cosmetic composition and dispense the beads in a way that would beak all the beads without leaving lumps or clumps when dispensed as a uniform colored composition having a color evenness related to a specific color.

As used herein, the expression "at least one" means one or more and thus includes individual components as well as mixtures and combinations. One of skill in the art will select the components to achieve the desired effect

As used herein, "about" shall generally mean within 20 percent, preferably within 10 percent, and more preferably within 5 percent of a given value or range. Other than in the operating examples, or where otherwise indicated, all numbers expressing quantities of ingredients and/or reaction conditions are to be understood as being modified in all instances by the term "about".

"Keratinous substance" or body surface, as used herein, includes but are not limited to, skin, hair and nails found on a human or other mammal.

The "beads" hereinafter are made from a variety of materials acceptable for biological use, provided that they can be gelled from solution and can be subsequently crushed, spread or otherwise dispersed on a desired body surface. Suitable gel materials include, but are not limited to, a wide range of homogenous or heterogeneous gel -forming polymers such as polysaccharides. Examples include natural and synthetic celluloses, such as hydroxyethyl cellulose, as well as polypeptides including proteinaceous materials, such for example gelatin; agarose. While the gel material itself is a useful end product, it is greatly preferred that the gel bead serve as a carrier for delivering an active agent to the skin or other body surface. The material used to form the bead will depend on the active to be delivered. The dispensability of the bead will depend on the gelled material and active used.

In one none limiting embodiment the active is a pigment. The pigment includes pigments, lakes and dyes. The different color of the beads is due to the at least one pigment selected.

Representative dyes which may be used according to the present invention including, but are not limited to, Sudan Red, DC Red 17, DC Green 6, .beta. -carotene, soybean oil, Sudan Brown, DC Yellow 11, DC Violet 2, DC Orange 5, annatto, and quinolone yellow.

The nacreous pigments which may be used according to the present invention may be chosen from, but not limited to, white nacreous pigments such as mica coated with titanium or with bismuth oxy chloride, colored nacreous pigments such as titanium mica with iron oxides, titanium mica with ferric blue or chromium oxide, titanium mica with an organic pigment chosen from those mentioned above, and nacreous pigments based on bismuth oxy chloride.

The pigments, which may be used according to the present invention, may be chosen from, but not limited to, white, colored, inorganic, organic, polymeric, nonpolymeric, coated and uncoated pigments. Representative examples of mineral pigments include titanium dioxide, optionally surface-treated, zirconium oxide, zinc oxide, cerium oxide, iron oxides, chromium oxides, manganese violet, ultramarine blue, chromium hydrate, and ferric blue. Representative examples of organic pigments include carbon black, pigments of D & C type, and lakes based on cochineal carmine, barium, strontium, calcium, and aluminum.

The beads are suspended in a clear base. An example of beads suspended in a clear base is found in FIG. 7.

The clear base can be anhydrous or water based as long as the beads remain suspended in the clear base. It is preferable for the base composition to remain clear after the beads are added and not color over time. A non-limiting example of a clear base is a dispersion of acrylic copolymers and crosspolymers in a water glycerin phase prepared under agitation and heat.

The beads suspended in a clear base are dispensed from a non-aerosol container having a screen in the dispensing head, chamber, or tube. An example of a non-aerosol container is found in FIG. 7.

There are many types of non-aerosol containers that dispense cosmetic products. The type of dispensing mechanism chosen depends on the type of cosmetic product and active ingredient used, the viscosity of the cosmetic product and the preferred application method. Some dispensing mechanisms use screens to generate foam from a liquid product in the container or pulverize a component of the cosmetic. A mixing device may be added or used in place of a screen to break the beads. The means of breaking the beads can be any device that provides the uniform colored composition of even colorness.

The cosmetic product described herein is not a uniform texture or color when placed in the container. Dispersion with a simple airless pump of the type commonly used in the cosmetics industry at a typical dispersion rate resulted in the non-uniform product depicted in FIGS. 1 and 2. The addition of a screen in the dispensing mechanism provided a way to uniformly break the beads, shear the broken beads, and blend the pigments to a uniform colored composition having a color evenness related to a specific color when dispensed.

The screen may be placed at the inlet of the pump, within the pump chamber or at the exit of the pump nozzle. Multiple screens may also be used where all screens are of the single mesh size or the screens are each of different mesh sizes

There are many types of non-aerosol containers that dispense cosmetic product and the type of dispensing mechanism will depend on the type of cosmetic product. Some dispensing mechanisms use screens to generate foam from a liquid product in the container. What is common among non-aerosol containers is that the product (whether an emulsion or water based) is a uniform texture when placed in the container. The dispensing mechanism is selected to control the rate of dispersion of the cosmetic product.

The concentration effect of the beads is seen in FIG. 6.

Table 1 contains data on the color evenness reading at various bead concentrations and screen size.

TABLE 1

Measurements were done on BYK-Gardner GmbH, #Cat No. 6397, Ser.

No. 1165389. Color measurement was done using a VAESTRO Image Analysis Module Definitions COLOR MEASUREMENT MODULE v 1.0.

Algorithm Description:

The Color Analysis algorithm provides color measurements under standard daylight conditions. The analysis is performed on a high-resolution image captured with a Canfield research capture device.

Output Definition :

Color Evenness - Measurement on overall variation in color values across the defined area, and how rapidly those colors change spatially within the defined area. An image with few distinguishable colors (determined from a* and b* color channels from L*a*b* color space), with very gradual changes in color will achieve a high color evenness score. Score is on a scale of 0.0 to 1.0.

An example of the use of the different color beads suspended in a clear base is to provide a visual impact on the store shelf. Visual impact drives sales. Examples of ways the dispensed colored composition having a color evenness related to a specific color provides the benefit of evening out the skin tone, enhancing the natural color of the skin, moisturizing the skin, and correcting the color of the skin prior to the application of makeup.

In an embodiment of this disclosure, each bead may include multiple colors wherein each bead has portions with different colors. For example a first portion of a bead may be of a first color and the second portion of the bead may be of a second color that is different than the first color. The different colored portion may divide the bead in hemispheres, quarters or any other geometrical arrangement. Alternatively, each bead may include more than two sections wherein each section is of a different color. FIG. 7 which was included in the originally filed application US Provisional 62/584,298 depicts beads where each bead included two different colors.

Another embodiment of this disclosure is one wherein each bead is of a single color and beads of different single colors are mixed in the composition. Beads of two or more single colors may be used in a composition of this type as can a mixture of single colored beads and multiple colored beads.

There are many types of non-aerosol containers that dispense cosmetic products. The type of dispensing mechanism chosen depends on the type of cosmetic product and active ingredient used, the viscosity of the cosmetic product and the preferred application method. Some dispensing mechanisms use screens to generate foam from a liquid product in the container or pulverize a component of the cosmetic. A mixing device such as a static mixer in the flow path of the pump may be added or used in place of a screen to break the beads. The means of breaking the beads can be any device that provides the uniform colored composition. Airless pumps with screens added to the flow path may be suitable for these applications. The Econ model pump from YonWoo Corporation, Incheon, Korea may be particularly suitable.

Samples 1 through 5 in Table 1 were produced with YonWoo Econ pumps with mesh screens inserted near the pump exit. Polyester mesh screens were used with 110, 130 or 150 openings per inch and opening widths of 0.23, 0.195 and 0.169 mm respectively.

Samples 6 through 9 were processed in a lab shearing device to demonstrate possible levels of color blending.

In addition to the color evenness made on samples 1 through 9, measurements of color of the samples in the L*a*b* scale were made. Table 2 includes data on both mean L*a*b* color across the sample surfaces and the standard of L*a*b* parameters across the surface. A lower standard deviation indicates a more uniform color of the dispensed product and better blending.
