Description

DETAILED DESCRIPTION

[0028] In an exemplary embodiment of the invention a wound healing skin-tone wound concealer ointment in different skin tones is made using different amounts of colored iron oxides, in the correct ratio and titanium dioxide and or zinc oxide and a protective emulsion matrix made of USP petrolatum and tocopherol acetate which is mixed together using a mortar and pestle, planetary mixer or roller mill into a thoroughly blended flesh tone concealer.

[0029] Preferably, the amount of the metal oxide component of the invention is no more than about 60% to 40% ratio added to the carrier emulsion absorption base, or matrix. The formula illustrated herein shows an average of 56% as the preferable amount of metal oxide component to the emulsion matrix carrier component but that could vary according to product requirements and minor differences in the amount of iron oxides needed for the different skin tones of the product.

[0030] The oxides and pigments herein are selected from the group consisting of titanium dioxide, zinc oxide, iron oxide, and mixtures thereof, and have an average particle size of from about 100 nm to about 500 nm, preferably from about 200 nm to about 350 nm. The titanium dioxide may be rutile type or anatase type. Rutile Titanium Dioxide is preferred in the preferred embodiment of the Invention because of the preferred lager average particle size. Another embodiment of the invention may use anatase titanium dioxide although rutile and anatase titanium dioxide are both suitable. The ratio of titanium dioxide to zinc oxide may be adjusted to increase the amount of zinc oxide in the mix or one of these may be omitted for a formula with just zinc oxide or just titanium dioxide as the white oxide component in the formula. It is preferable to use both of these oxides in the formula rather than just one or the other, but a cosmetic embodiment of the invention suitable for concealing wounds but sold or marketed as a cosmetic would use only titanium dioxide without zinc oxide. The preferred embodiment of the invention would blend the determined amounts of titanium dioxide and or zinc oxide and iron oxides with a carrier emulsion matrix which is a suitable dermatologically protective liquid such as petrolatum and a viscous vitamin E component such as tocopherol acetate (synthetic vitamin E oil) together with the petrolatum to form a protective concealer suitable for applying to wounded and healing skin. By adding Vitamin E to the carrier emulsion matrix in the form of tocopherol acetate or other organic forms of vitamin E, the skin receives direct anti-oxidant protection from any free radicals created by the degradation of the titanium dioxide or zinc oxide from extended sun exposure. Although the use of non-Nano sized particles of these oxides are considered safe for use in the Sun, the addition of vitamin e oil minimizes the potential skin damage from free radicals.

[0031] In a preferred embodiment of the invention described herein, the pigments are iron oxide powders in the colors red, brown and yellow at varying ratios for each skin tone which are blended with titanium dioxide and or zinc oxide with USP petrolatum and tocopherol acetate (synthetic vitamin E oil) in a mortar and pestle, planetary mixer or a roller mill or other industrial mixer for large quantities to create the medicinal concealer compound in flesh tones. Increasing or decreasing the ratios of iron oxide color mixtures and adding other colors like blue or darker brown for example changes the concealer to match different racial skin tones.

[0042] The above formulations may be prepared as follows: The wound concealer is mixed and thoroughly blended in a mortar and pestle, planetary mixer, or roller mill or other system normally used to mix a semi solid cosmetic product and then injected or pressed into to container. Test samples were prepared with a planetary mixer with a stainless steel bowl with blade mixer. The mixture was then transferred to an extrusion filling system similar to a cookie press that contained the mixture in a metal tube and a piston plunger pressed a measured amount of the mixture through a ½″ diameter hole into each one-ounce round metal tin container and sealed with a screw top lid.

[0043] Cleaning, sanitizing and drying was done on the stainless mixing bowl and mixing blade as well as other stainless-steel bowls, measuring cup, stainless steel spoons, long flat spatulas and the extrusion filling system. The preparation area and preparation table were cleaned and sanitized. A heavy-duty planetary mixer was placed on the table with the scale, the mixing bowls. A precision digital scale was used to measure out the ingredients by weight and place the measured ingredients into stainless steel bowls. Additional steps were also take to ensure the product was uncontaminated such as wearing N95 mask, face shield, and rubber gloves when measuring the ingredients, mixing the ingredients, and packing the competed mixture into the containers.

[0044] To make fifty ounces of the formula as one example in the color Bisque in the cosmetic form of the invention without the zinc oxide included, 725 grams of purified titanium dioxide was measured out, but if zinc oxide were to be used it would also be a ratio of 60% titanium dioxide and 40% zinc oxide or a variation thereof equaling 725 grams rather than 725 grams of just titanium dioxide or just zinc oxide.

[0045] 25 grams of cosmetics grade yellow iron oxide was measured, 40 grams of brown iron oxide, and 40 grams of red iron oxide. 400 grams of medical grade white petrolatum USP was measured out onto a flat tray, and 200 grams of tocopherol acetate oil in the measuring cup. Tocopherol acetate was poured into the mixing bowl and then the measured iron oxides and titanium oxide was poured into the 6 quart mixing bowl. The petrolatum was then placed in the bowl on top of the powder and the mixer was started. The bowl and blender blade was scraped during the process with the long stainless spatulas and the mixture was blended completely for thirty minutes at room temperature (20 to 25 Celsius). The mixed formula was then transferred from the mixing bowl to a covered sanitized stainless steel bowl or container to wait for the packaging or filling process. The mixture was placed into the extrusion filling device tube and a piston plunger in the device pushed the mixture out the hole into a round tin that was below and in close proximity to the extruder device orifice in measured amounts into the container which was then sealed and labeled.

[0046] The same mixing process and the filling process described herein would be also used to make any other skin tone color variations by using different ratios of the iron oxides. The formula examples shown herein only produce four colors but other variations in the ratio of the pigments would create a much wider variety of colors which is anticipated and intended in the invention described. Based on the disclosure herein, anyone skilled in the art could create a wide variety of skin tones beyond the examples contained herein. The organic version of the invention can also be made using this method by substituting the petrolatum and tocopherol acetate in the formula with organic ingredients like Shea butter and vitamin e oil, or similar ingredients like jojoba oil and Aloe Vera. The formula can be packaged into squeeze tubes or other containers by minimally heating the blended formula (40 to 45 Celsius) to allow for mechanically rapid filling open ended squeeze tubes using a filling system other than an extrusion type of filling system.

[0047] Additional formulations may be made in accordance with the process set forth in these Examples in order to create compositions according to this invention which may contain one or more active ingredients in addition. The ingredients of the example formulation could be substituted with a different carrier other than white petrolatum or any of the carriers contemplated in the forgoing examples. Another embodiment of the invention as an emulsion could be achieved with water-based extracts and organic oils such as Shea butter, Cannabis Oils, or synthetic oils not based on petrolatum for an ointment base. Another embodiment of the invention could be achieved with a wax-based balm as well by adding the concealing component described in the invention.

[0048] The carrier ointment base combined with the concealer component of this invention shown in the examples provides a cosmetically concealing composition of skin protection ointment and can be formulated with additional topical active materials, as set forth to achieve desired therapeutic results for the skin with the concealer properties of a cosmetic concealer. The following formulations may be produced according to the procedure set forth above in the example formulation with the understanding that the process may be adjusted to suit the specific materials. Adjustments may include, but are not limited to, pH of the final product, order of addition of raw materials and/or processing temperatures as necessary. The stability of this ointment was shown in tests of one month at room temperature, 37° C. and 45° C. with no loss of homogeneity was observed.

[0049] The foregoing example of the invention includes the addition of zinc oxide, titanium dioxide and iron oxides to create a skin tone opaque appearance on the skin when mixed in an emulsion matrix with a petrolatum or organic oil based medicated ointment formulation and it will be obvious to those skilled in the art that other medicated ointments and protectant balms and creams such as Aquaphor, Epicure, Vaseline, and other skin balms and ointments could be used as the emulsion matrix component of the invention in order to add the concealing properties of the invention to other applications or products. In addition other suitable medicaments could be used in the formula to add healing properties within FDA guidelines such as, hydrocortisone, iodochlorhydroxypryin, lidocaine, pyrilamine maleate salicylic acid, allantoin, resorcinol, chlorhydroxyquinoline, bufexamic acid might be added.

[0050] It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative examples and that the present invention may be embodied in other specific forms without departing from the essential attributes thereof, and it is therefore desired that the present embodiments and examples be considered in all respects as illustrative and not restrictive, reference being made to the appended claims, rather than the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
