Description
BACKGROUND OF THE INVENTION

1. Technical Field


This application relates generally to cosmetic compositions and to methods of making and using the cosmetic compositions. In particular, this application relates to moisturizing compositions comprising one or more pigments which, when applied to the skin, mask skin imperfections and provide more uniform skin tone and to methods of making and using these compositions.


2. Background of the Technology


Consumers are increasingly interested in improving the appearance of their skin. In particular, consumers want the skin on their body to look more even and more translucent and to look clear and unblemished. Consumers also want their skin to look and feel soft, smooth and unwrinkled. This desire for improved skin appearance is not limited to the skin of the face but also includes the neck and chest, the hands, the legs, the arms and anywhere else skin may be visible.


Consumers are currently using a variety of products and procedures to “fix” and/or prevent body skin problems. For example, scars and pregnancy rashes have been treated using glycolic serums and scar faders. Consumers with skin that is not sufficiently shiny, smooth or translucent or that need help with wrinkles, sun spots, pregnancy marks, etc. have employed resurfacing treatments (e.g., with alpha or beta hydroxys or peptides), microdermabrasion, exfoliating treatments, and skin fading treatments. Consumers with bumpy, dry or rough skin or with fine lines and wrinkles have employed exfoliants (e.g., sugar or salt). Consumers with uneven skin tone have employed fading creams. Consumers with lines and wrinkles have employed botox, collagen or laser resurfacing treatments. In addition, uneven skin tone has been treated using fading creams and visible veins have been treated using laser treatment. Tanning has been accomplished using self tanners and spray tanners. The procedures being employed by consumers also include plastic surgery and various dermatological approaches.


Many of these treatments have known shortcomings. For example, glycolics can cause irritation, especially for users having sensitive skin. Exfoliation treatments such as sugar and salt scrubs can be harsh to the skin. Dermatological treatments and collagen and botox injections can be costly. In addition, today's consumers want “immediate gratification” (i.e., they want to see and/or feel a difference in their skin immediately). In addition, today's consumers want products that will help conceal lines, wrinkles and other problems in addition to cleansing and moisturizing the skin.

DETAILED DESCRIPTION OF THE INVENTION

Skin care issues can typically be grouped according to the skin tone of the user. Thus, consumers having a particular skin tone will tend to have similar concerns or issues with the appearance of their skin. Skin tones can be classified using the Fitzpatrick Phototype Scale {J. Amer. Acad. of Dermatology: 46(2) Supplement (2002); 48(6) S139-S142 (S2003)}. The Fitzpatrick Phototype Scale divides skin types into six categories ranging from ivory white to dark brown or black. The following table illustrates some general characteristics of each of the Fitzpatrick skin phototypes.

The compositions described herein can be skin care lotions that can be applied to the skin in a conventional manner. The formulations described herein can be customized to address the specific skin care needs of diverse skin types. The formulations can be “customized” to immediately improve the appearance and texture of skin while other ingredients in the formulations continue to provide additional benefits over time with continued use of the product. The formulations described herein can therefore be considered hybrid products that incorporate the best properties of a makeup, a skin care emollient lotion and a fortifying agent (e.g., a sunscreen).


According to one embodiment, the compositions described herein are oil-in-water emulsions. These oil-in-water emulsions, however, can contain a non-ionic water-in-oil emulsifier based on silicone (Cetyl PEG/PPG-10/1 Dimethicone). The incorporation of Cetyl PEG/PEG-10/1 Dimethicone into the oil phase was found to improve resistance to color transfer from skin to clothing and provide improvement to the “feel” of the formulation when applied to skin. Further, when a sunscreen was added to formulations including Cetyl PEG/PEG-10/1 Dimethicone, it was found that the level of sunscreen required to achieve an SPF of 16 could be dramatically reduced. This effect was achieved with relatively low levels of the Cetyl PEG/PEG-10/1 Dimethicone (i.e., 0.4 wt. % based on the total weight of the composition). In contrast, the manufacturer recommends use levels of 1.5-2.5 wt. % of Cetyl PEG/PEG-10/1 Dimethicone.


The compositions can also be formulated as water-in-oil emulsions.


The compositions described herein can also include pigments (e.g., iron oxide pigments). The pigments may be surface treated with an acrylic polymer. For example, the pigments can be surface treated with a composition comprising water, an acrylate/octyl acrylate copolymer, a sodium acrylate/sodium acryloydimethyl taurate copolymer and aminomethyl propanol. A material of this type is available from Kobo Products, Inc. It was found that iron oxides with other surface treatments (e.g., Sympholight which is an iron oxide/silica) did not result in compositions having comparable color transfer resistance. Although pigments having acrylic polymer surface treatments are preferred, pigments having no surface treatment or pigments having other surface treatments can also be used.


The iron oxide pigments included in the formulations can help even natural skin tone variation found within each general skin type. Unexpectedly, it was found that the iron oxide pigments, when used in the base formulation, can have a strong color impact on the mass tone of the skin with minimal color transfer from skin to clothing.


In addition to the above, color transfer from the body to clothing can be further minimized by incorporation of hydrogenated polycyclopentadiene (e.g., Koboguard 5400 IDD). This material is a film-forming low molecular weight polymer that is extremely stick and tacky. For this reason it is not commonly used in body lotions. To remove the sticky, tacky property the formulation and further reduce color transfer, isohexadecane (e.g., Permethyl 101A) can be added to the formulations. The hydrogenated polycyclopentadiene and isohexadecane can be pre-mixed and added to the formulation after the oil and water phases are combined and the resulting emulsion has formed. The hydrogenated polycyclopentadiene and isohexadecane can be added to the emulsion when the emulsion is at a temperature below 50° C. In this manner, a further reduction in pigment transfer can be realized.


Other film forming agents can also be used. By film forming agents, it is meant materials which, upon drying, produce a continuous film on skin, hair, or nails. Exemplary film forming agents which can be used in the compositions are set forth in the following table.

The above listing of film forming agents is not exhaustive and other film forming agents can also be used. Further, combinations of film forming agents can also be used.


When one or more sunscreen agents (e.g., oxybenzone and/or octylmethoxycinnamate) were added to a formulation comprising hydrogenated polycyclopentadiene and isohexadecane, it was discovered that an SPF of 16 could be achieved with relatively low levels of the sunscreen agents. While not wishing to be bound by theory, it is believed that this phenomenon may be related to the solubility properties of isohexadecane. Moreover, oxybenzone is insoluble in isohexadecane and octylmethoxycinnamate is soluble in isohexadecane. It is believed that the relative solubilites of these ingredients has sufficiently shifted the action spectra of the sunscreens resulting in more efficient SPF results. This is desirable in a lotion containing sunscreens with respect to both toxicology and improved aesthetic performance.


Reflective pigments can also be incorporated into the compositions. These pigments can be titanium/mica and or iron oxide/mica blends with no additional surface coating. The blend of reflective pigments employed can vary depending on the skin type of the user. The particle size of the reflective pigments can range from 4 to 75 microns.


The compositions can be oil-in-water emulsions comprising a discontinuous oil phase dispersed in a continuous aqueous phase. The compositions can also be in the form of lotions.


As set forth above, the compositions include various color pigments the concentrations of which can be adjusted for the skin tone of the user. For example, the compositions can include a combination of red, black and yellow pigments. Exemplary pigments include iron oxides. The pigments (e.g., iron oxides) can be surface treated. According to one embodiment, the compositions comprise iron oxide pigments surface treated with a composition comprising an acrylic polymer. Compositions formulated for the lighter skin tones (e.g., Fitzpatrick I and II phototypes) can be formulated with a pigment package which minimizes the appearance of red splotches on the skin. Compositions formulated for intermediate skin tones (e.g., Fitzpatrick Phototype IV) can be formulated with a pigment package which highlights the natural skin color and hue of the user. Compositions formulated for the darker skin tones (e.g., Fitzpatrick Phototypes V and VI) can be formulated with a pigment package which provides enhanced sheen and luster to the skin of the user.


Exemplary pigments include iron oxides such as hydrated ferric oxide (FeHO2), ferric oxide (Fe2O3), ferrosoferric oxide (Fe3O4). As set forth above, the iron oxide pigments can be coated with a composition comprising an acrylic polymer. An exemplary acrylic polymer is an ethyl methacrylate/n-butyl acrylate/2-methylhexyl acrylate copolymer. A suitable material of this type is available from Kobo Products, Inc. The use of iron oxide pigments coated with an acrylic polymer increases the transfer resistance of the compositions.


As also set forth above, the compositions can also include reflective pigments such as mica. The mica can be coated (e.g., with titanium dioxide or iron oxide) such that the mica pigments act as light diffusers. The compositions formulated for the lighter skin tones (e.g., Fitzpatrick Phototypes I and II) can include red and silver mica pigments whereas the compositions formulated for the darker skin tones (e.g., Fitzpatrick Phototypes V and VI) can include copper, bronze and gold mica pigments. Compositions formulated for intermediate skin tones (e.g., Fitzpatrick Phototype IV) can include amber and gold mica pigments.


Color transfer resistancy (e.g., from the skin of the user to clothing) can be further enhanced by including various polymers (e.g., film formers) in the compositions. Exemplary film forming polymers include hydrogenated polycyclopentadiene.


Exemplary compositions for the lighter skin tones of the Fitzpatrick Skin Phototype Scale (e.g., Types I-V) can also include one or more sunscreen agents. Exemplary sunscreen agents include but are not limited to octyl methoxycinnamate, octylsalicylate, oxybenzone and meradimate. Compositions formulated for the lighter skin tones (e.g., Fitzpatrick I and II phototypes) can also be formulated with antioxidants to reverse the effects of ultraviolet radiation as well as other insults to the skin.


Skin care compositions can also include a humectant (e.g., butylene glycol), a thickener (e.g., ammonium acryloyidimethyltaurate/vinyl pyrrolidone copolymer or hydroxyethyl acrylate/sodium acryloyldimethyl taurate copolymer), a chelating agent (e.g., disodium EDTA), a preservative (e.g., methylparaben, propylebaraben, DMDM hydantoin or combinations thereof), a non-ionic emulsifier (e.g., ceteareth-20), and/or a fatty alcohol (e.g., cetearyl alcohol, cetyl alcohol or combinations thereof).


Exemplary compositions for the darker skin tones (e.g., Fitzpatrick Skin Phototypes V and VI) can also include dicaprylyl ether. An exemplary concentration of dicaprylyl ether is about 3.0 weight percent based on the total weight of the composition.


The compositions can also include a fragrance.


The compositions can also include a matifying agent. An exemplary matifying agent is a dimethicone/cyclopentasiloxane gel made by dispersing oil swellable polydimethylsiloxane particles in a mixture of dimethicone and cyclopentasiloxane. A material of this type is available from Grant Industries and is sold under the tradename Gransil.


The compositions can include an alkylated polyether polydimethylsiloxane compound. An exemplary alkylated polyether polydimethylsiloxane compound has the following general structure:

wherein R is an alkyl group (e.g., a cetyl group) and wherein m, n, x and y are integers. A material of this type is sold under the trademark Abil® EM 90 (INCI name Cetyl PEG/PPG-10/1 Dimethicone).


The compositions can also include an emollient package. Representative emollient packages for compositions for fair skin tones (e.g., Fitzpatrick Skin Phototypes I and II), medium skin tones (e.g., Fitzpatrick Skin Phototypes II and III), tan skin tones (e.g., Fitzpatrick Skin Phototypes III-V) and deep skin tones (e.g., Fitzpatrick Skin Phototypes V and VI) are set forth in the following table.

The compositions may also contain additional materials such as, for example, fragrances, fillers, preservatives, antioxidants, and emulsifiers. Exemplary emulsifiers include any of the surfactants (e.g., nonionic, anionic, cationic or zwitterionic) used to form emulsions.

As can be seen from the above table, each of the compositions includes a plurality of pigments (i.e., iron oxides treated with an acrylic polymer), a water-in-oil emulsifier, and an emollient package.


Compounding Procedure


An exemplary compounding procedure is described below.


The aqueous phase is heated to a temperature over 70° C. (e.g., 75-78° C.). The water phase can include water, butylene glycol, Disodium EDTA, Aristoflex AVC and propyl paraben and methylparaben.


The oil phase is heated to about 80° C. The oil phase can include glyceryl stearate & PEG 100 stearate, cetearyl alcohol, ceteareth-20, cetyl alcohol, Cetyl PEG/PPG10-1 Dimethicone, Bernel ester DID, Shea butter, octyl myristate, ethylhexyl isononate, and C12-15 alkyl benzoate.


After the oil phase is added to the aqueous phase at the above temperatures and the resulting mixture is cooled to about 50-55° C., the iron oxide pigments are added. The iron oxide pigments can be pre-mixed in water. Pre-mixing in water can help to further hydrate the polymer to minimize polymer specs in the final batch.


The silicone/polymer/silicone elastomer/solvent phase is premixed at room temp. This phase can include Koboguard 5400 IDD, Permethyl 101A, Dimethicone 200 5 CS, and Gransil KO.


This phase is added at a temperature at or below 55° C. (e.g., 50-55° C.) after the emulsion has formed. In this manner, reduced pigment transfer as well as a unique feel of the formulation can be achieved.


After the above is well mixed, the mica effect colors can be added (e.g., at a temperature of 45-50° C.), followed by the DMDM Hydantoin (a preservative) and the fragrance (e.g., at a temperature of 400° C.).
