Abstract
A cosmetic stick having a base, including a solidifying agent and a volatile solvent, and microencapsulated pigment particles. The outer shell of the microencapsulated pigment particles is softened but not destroyed by the volatile solvent.
Description
COSMETIC STICKS CONTAINING MICROCAPSULES The present invention relates generally to a cosmetic stick containing a microencapsulated ingredient. More particularly, this invention relates to a pigmented cosmetic stick having an encapsulated pigment or other encapsulated active ingredient within a volatile solvent base. Such a stick having an encapsulated pigment within a volatile solvent base provides enhanced color payoff and improved feel and smoothness on application to the skin.
BACKGROUND OF THE INVENTION Encapsulated pigments for use in cosmetic compositions are known in the art, as are encapsulated oils and other encapsulated active ingredients. U.S. Patent No. 5,382,433, owned by the assignee of the present invention, provides a long wearing cosmetic composition having coacervated pigment microcapsules incorporated into a compatible anhydrous base.
As explained in that patent, prior art cosmetics having encapsulated pigments tended to feel rough and gritty due to the presence of the residual microcapsule material in the cosmetic. Attempts to produce a smoother product by mixing the encapsulated pigments with oils or emollients were unsuccessful, because the resulting dispersions caused the microcapsules to weaken and rupture too easily during handling. Moreover, these formulations provided an insufficient concentration of pigment.
Volatile solvent based cosmetics account for a sizable and growing portion of the cosmetic market. Yet, until now, volatile solvents were not thought to be compatible with cosmetic microcapsules, since it was believed that the volatile solvents would
completely dissolve the microcapsules and render them useless .
It has surprisingly been found that microencapsulated pigments formed according to the such methods as those disclosed in U.S. Patent No. 5,382,433, discussed above, can successfully be incorporated into cosmetic bases containing volatile solvents, without sacrificing the performance of the microcapsules to deliver high concentrations of pigment and to improve color payoff and wear properties. Moreover, it has been found that these compositions have superior feel on application, and are not rough or gritty.
SUMMARY OF THE INVENTION
Against the foregoing background, it is a primary object of the present invention to provide a cosmetic composition having microcapsules, containing pigment or other ingredients, in a volatile solvent base.
It is another object of the present invention to provide such a composition that enhances wear, color payoff and pigment concentration.
It is still another object of the present invention to provide such a composition that is smooth and non-gritty on application to the skin.
It is yet another object of the present invention to provide the foregoing benefits in a solid or semi-solid cosmetic. To the accomplishment of the foregoing objects and advantages, the present invention, in brief summary, comprises a cosmetic stick having a base, including a solidifying agent and a volatile solvent, and a microencapsulated pigment particle or particles (referred to herein as particles) , wherein the outer
shell of the microencapsulated pigment particles is softened but not destroyed by the volatile solvent.
DESCRIPTION OF THE PREFERRED EMBODIMENTS The preferred cosmetic compositions of the present invention have a microencapsulated ingredient incorporated into a volatile solvent-based solid or semi-solid base. Preferably, the microencapsulated ingredient is a pigment. This microencapsulated pigment is then incorporated into a cosmetic base containing a volatile solvent, without sacrificing the performance of the microcapsule or microcapsules (referred to herein primarily as microcapsules) to deliver a high concentration of pigment. In addition, the resulting cosmetic has improved color payoff and wear properties. Moreover, it has been found that the composition has superior feel on application.
While a microencapsulated pigment is preferred for use in the composition of the present invention, it is apparent that microcapsules containing other cosmetically useful ingredients, such as emollient oils, sunscreens, healing or treatment agents, vitamins, and the like, would also come within the scope of the present invention. The microcapsules can be added alone or in combination with another microencapsulated ingredient to the cosmetic base. The cosmetic composition containing these ingredients is not gritty or rough, and provides improved ingredient payoff and wear.
In the prior art, the color component is typically dispersed throughout a suitable anhydrous base or vehicle. The pigmented solid particles give the cosmetic its characteristic color, texture or sheen. In contrast with such freely dispersed
pigments, a microencapsulated pigment provides benefits such as longer wearing color and renewability without reapplication. For example, normal activities such as talking, smiling and eating cause microcapsules within a lipstick that has been applied to the lips to rupture and dispense color long after initial application.
Any inorganic or organic pigment or colorant approved for use in cosmetics is suitable for use in the present invention. Preferred pigments include the lakes, iron oxides, titanium dioxide and hydrophobic dyes. The microencapsulated pigments may be formed according to the methods disclosed in the art, such as those disclosed in U.S. Patent No. 5,382,433, discussed above and incorporated herein by reference, which sets forth several preferred methods of encapsulation.
Of those methods, the coacervation method is more preferably employed to encapsulate the pigment or other ingredient or ingredients of the present invention. As disclosed in greater detail in U.S. Patent No. 5,382,433, this method involves first dispersing the color component or pigmented solid in a liquid carrier, preferably a nonvolatile solvent. The liquid dispersion is emulsified, and a complex of colloidal material is added to the external phase. The colloidal material is then reacted to form a deposit or shell on and around each droplet. The temperature of the solution is then lowered in order to gel and harden the shell wall material. Further curing of the shell wall material by chemical agents can also be performed. The preferred colloidal materials for use in this preferred process include gelatin and gum arabic.
A stable, dry, free flowing powder is formed. The microcapsules making up this powder are preferably from about 2 to about 20 microns in diameter. However, due to the softening effects of the composition of the present invention, microcapsules of greater size can be used without an unacceptable feeling of roughness or grittiness on application of the cosmetic composition to the skin. The dimensions of the microcapsules and their cores can be controlled by manipulating the reaction conditions, as is known in the art. Additional methods of encapsulation can also be used, such as additional in situ polymerization reactions and polycondensation encapsulation techniques. The microcapsule powder can then be incorporated into the cosmetic base. The microcapsules are preferably present in the cosmetic composition at up to about 60% by weight of the base vehicle, with an amount in the range of about 2% to about 20% by weight being more preferred.
The present invention contemplates the use of a cosmetic base containing a volatile solvent. Such a volatile solvent is typically used as a quick-drying carrier for a film-forming agent such as sucrose acetate isobutyrate. The volatile solvent remains in the cosmetic composition until it is applied to the skin, hair or other surface. The volatile solvent then rapidly evaporates, leaving the remaining cosmetic ingredients, preferably entrapped within a cosmetic film, on the skin or other surface.
Apparently, the volatile solvent in the base softens or plasticizes the outer shell of the microcapsules in situ. This minimizes or eliminates the typical gritty feel of the microcapsule material. Moreover, it is believed that the solidifying agent
that binds the semi-solid or solid composition acts to maintain the structure of the microcapsule, and thus lock the microcapsule' s contents in place and enable the microcapsule to remain functional. Any cosmetically acceptable volatile solvent can be used in the cosmetic compositions of the present invention. Preferred volatile solvents for use in the present invention include volatile hydrocarbons, such as isododecane and other isoparaffins, and volatile silicones such as cyclomethicone .
Any cosmetically acceptable solidifying agent can be used in the solid or semi-solid bases of the present invention. The solidifying agent is preferably a wax. Preferred waxes for use in the cosmetic compositions of the present invention include candelilla, beeswax, microcrystalline petroleum wax, paraffin wax, ceresine wax, ozokerite and carnauba. Moreover, these waxes can also function as film formers. In addition, other binders and structuring agents can be used in these compositions as solidifying agents, provided they give support to the cosmetic and to the softening microcapsules therein. Cosmetic compositions according to the present invention are preferably in the form of wax-based cosmetic sticks, such as lipsticks, concealers, or stick eyeshadows. Other solid or semi-solid compositions, such as foundations, blushes and potted lip colors, can also be used. A preferred lipstick composition according to the following invention is set forth in Example 1.
