Packaged solvent-containing cosmetic composition

TECHNICAL FIELD

[0001] The invention is in the field of packaged cosmetic compositions.

BACKGROUND OF THE INVENTION

[0002] One problem in the packaging of cosmetic compositions is that the composition itself may contain ingredients that react with chemical composition of the container. It is a common packaging problem to discover that the package into which the cosmetic formula is intended to be sold is not compatible with the cosmetic formula. This happens most often when the cosmetic compositions contain solvents—substances that present in the formula for the purpose of solvating other cosmetic ingredients. The most desirable cosmetic compositions often contain ingredients that in the strictest sense are not compatible with the other ingredients in the formula and require solvation in order to be properly formulated into the composition. For example, many of the resins and polymeric materials used in cosmetics are essential for forming a cosmetic film. Often these resins, by themselves, are insoluble or otherwise incompatible with the formula unless solvated by another ingredient in the cosmetic which is compatible with both the resin and the other ingredients in the formula. Nail enamels, transfer resistant lipsticks, and other types of long wearing color cosmetics provide examples of this phenomena. The solvents used to solvate the resins and polymers in these types of compositions often require that the composition be sold in glass containers. Glass is nearly inert and non-reactive with most, if not all, of the ingredients found in cosmetic formulas.

[0003] As might be imagined, however, glass containers have drawbacks. They are heavy, which results in significantly higher shipping costs. When millions of units are shipped in a year, the amount of money can be significant. Glass also breaks more readily than thermoplastic materials, and broken glass presents a number of different hazards.

[0004] For years cosmetics companies have been interested in finding suitable non-glass containers for packaging cosmetics. Containers made from thermoplastic polymeric materials such as HDPE (high density polyethylene), LDPE (low density polyethylene), styrene, and similar polymers are known. However, they suffer from a number of drawbacks, most notably that they are not optically clear. Packaging of cosmetic products requires that the containers be aesthetically pleasing. Any thermoplastic substitute for a glass container must provide aesthetic and functional properties equivalent to glass in terms of optical clarity, inertness, and appearance. Unfortunately, the plastic containers currently used for cosmetic compositions simply do not measure up. One chronic problem is that while the plastic may at first appear optically clear, after a time the cosmetic composition found within the container begins to interact with the thermoplastic material and yellowing of the container results. With respect to nail enamel in particular, the volatile organic solvents that are used are particularly reactive with thermoplastic materials. While there are commercial nail enamels that have been sold in plastic containers, the containers exhibited a yellowish cast, and in some cases the nail enamels had degraded the thermoplastic material used to make the container.

[0005] Accordingly, there is a need for cosmetic containers that provide the beneficial properties of glass containers, e.g. optical clarity and inertness, and at the same time are aesthetically pleasing, light weight, and suitable for use with a wide variety of cosmetic products. Such containers must also be easy to decorate according to the standard decorating methods used with cosmetic packaging. Most surprisingly, it has been discovered that cosmetic containers made from polycycloolefin resins are superior in terms of clarity, inertness, and aesthetics, and are suitable for use with solvent-containing cosmetic compositions.

[0006] It is an object of the invention to provide a packaged solvent-containing cosmetic composition in a container comprised of a polycycloolefin resin.

[0007] It is a further object of the invention to provide a method for storing and dispensing a solvent-containing cosmetic composition comprising storing the composition in a container comprised of a polycycloolefin resin.

[0008] It is a further object of the invention to provide, specifically, a packaged nail enamel composition comprised of a nail enamel composition contained in a thermoplastic container comprised of a polycyloolefin resin.

SUMMARY OF THE INVENTION

[0009] The invention is directed to a packaged cosmetic composition comprised of a solvent-containing cosmetic composition contained in a container comprised of a polycycloolefin resin.

[0010] The invention is further directed to a method for storing and dispensing a solvent-containing cosmetic composition comprising storing the composition in a container comprised of a polycycloolefin resin.

[0011] The invention is further directed to a packaged nail enamel composition comprised of a nail enamel composition contained in a container comprised of a polycycloolfin resin.

DETAILED DESCRIPTION

[0012] The preferred packaged cosmetic product of the invention comprises a solvent-containing cosmetic composition packaged in an optically clear, self-supporting container comprising a polycycloolefin resin.

[0013] I. The Solvent-Containing Cosmetic Composition

[0014] The term “solvent” means an ingredient that is operable to solvate another ingredient found in the cosmetic composition and render it soluble or compatible in the cosmetic composition. Whether an ingredient acts as a solvent will depend on the other ingredients that are in the cosmetic composition into which it is incorporated. The term “compatible” means, with respect to an ingredient, that it can be incorporated into a particular cosmetic composition without “kicking out” or destabilizing the composition.

[0015] Generally, the cosmetic composition stored in the package will comprise from about 0.001-99%, preferably about 0.005-85%, more preferably about 0.1-50% by weight of the total composition of one or more solvents.

The term “self-supporting” means that the container is not in a compressible form, such as a gel pack or the like, but rather if placed on a solid, flat surface will be able to hold its place and maintain its shape.

[0099] Preferably, the polycycloolefin resin is prepared by polymerizing the following monomers of the formula I or II:

[0100] wherein R1, R2, R3, and R4 are each independently hydrogen, hydrocarbon, halogen, hydroxy, ester, alkoxy, cyano, amido, imido, or silyl, or a hydrocarbon substituted with hydrogen, hydrox, ester, alkoxy, cyano, amido, imido, or silyl, provided that two or more of R1, R2, R3, or R4 may combine with each other to form an unsaturated bond, single ring, or multi-ring, the single ring or multi ring may have a double bond or may form an aromatic ring, and R1 and R2 together may form an alkylidene group or R3 and R4 together may form an alkylidene group; either alone or in combination with bridging groups of the general formula:

[0101] wherein R5 and R6 are each independently hydrogen, alkyl, or aryl, and x is from 1-1000.

[0102] More preferably the polycycloolefin resin has a refractive index of greater than 1.5, a glass transition temperature of about 100 to 160° C., a tensile strength of about 61, a tensile modulus of about 2400, and a tensile elongation of about 20. The most preferred container has a refractive index of 1.53 and a glass transition temperature of 136° C. Preferred polycycloolefin resins are made by Zeon chemicals under the Zeonor and Zeonex trademarks. Zeonor 1410R is the most preferred polycycloolefin resin.

[0103] The polycycloolefin resin may be used to make a wide variety of suitable containers, including bottles, boxes, jars, or any other form suitable for storing the solvent-containing cosmetic products. The containers may be made in a variety of ways, including blow molding or by separate molding of individual pieces which are assembled prior to use.

[0104] Containers are prepared by blow molding the polycycloolefin resin in the standard manner known for blow molding plastic containers and other types of implements.

[0105] While the invention has been described in connection with the preferred embodiment, it is not intended to limit the scope of the invention to the particular form set forth but, on the contrary, it is intended to cover such alternatives, modifications, and equivalents as may be included within the spirit and scope of the invention as defined by the appended claims.
