ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to the field of makeup or cosmetic compositions which are carried as individual disposable devices to which a makeup formulation has been applied and dried and which delivers a smudge/smear resistant pigmented makeup composition to the face, head, body, hair, clothing or other surfaces of the user after being wetted, leaving a layer of color that dries to a smudge resistant, transfer resistant non-staining film which is soap and water washable.
BACKGROUND OF THE INVENTION
Cosmetic or makeup compositions which are designed to be applied to a wearer's body are usually comprised of a composition either pigmented or not, that is immediately usable or applicable to be applied to the body of the user. This presents somewhat of a problem in that the compositions must be provided in containers or otherwise so that they will not come into contact with other objects in a non-desired fashion as they are transported or carried on one's person. The need for containers creates additional expense in the form of the cost of the container and the cost of freight to ship the additional weight; the weight and space required for containers reduce the portability and convenience of the cosmetic composition in its ultimate and intended use.
An object of the present invention is to formulate a cosmetic composition and to provide an article of commerce and a method of use of the article so as to obviate these difficulties.
SUMMARY OF THE INVENTION
The present invention is directed to a composition, its absorption onto an absorbing medium such as natural or artificial sponges or other absorbent material which can be sold in commerce and when it is time to use the article of commerce, the absorbable material containing the composition is rewetted in water or a suitable volatile solvent which then in effect reactivates the composition which is then applied to the body of the user.
The composition as formulated, by weight is as follows: (a.) 20-98% volatile solvent, (b.) 0.1-20% polymer, and (c.) 0.1-40% powder.
It is also desirable although not absolutely essential that one add (d.) 0.01-5% gums or hydrophilic colloids and (e.) 0.01-5% surfactant (surface active agent).
The composition when suitably prepared is absorbed (soaked) into a natural or synthetic sponge or other absorbent material to totally impregnate the absorbent material which is thereafter dried either by natural or artificial heating means. Other absorbent materials are natural and synthetic fibers or the processed thread or cloth from them, such as cotton, wool, rayon, nylon and paper. The drying drives off the volatile solvent leaving the remaining materials in the absorbent material. The invention contemplates absorbing the cosmetic composition (after drying) on the absorbent material in amounts from 40% to 1000% based on the weight of the absorbent material. When it is desired to utilize the article of manufacture by the ultimate consumer, all one does is remoisten the absorbent material with water or another suitable volatile solvent. When the absorbent material is then applied to the skin or other parts of a person, the cosmetic composition comes off on the user and dries forming a smudge resistant film.
DETAILED DESCRIPTION
The term volatile solvent as utilized herein is a liquid material which is capable of dissolving and dispersing the other ingredients of the composition and then be evaporated either at ambient or higher temperatures. The dried composition is capable of being rewetted with water or another solvent, thereby reactivating the composition for later use. Volatile solvents that are utilizable in the present invention include water, alcohols (ie., ethanol, isopropanol, benzyl alcohol, butyl alcohol), hydrocarbons (ie., butane, isoparaffins, isopentane, mineral spirits, petroleum distillates, isododecane, deodorized kerosene, xylene), ketones (ie., acetone, MEK, MIBK), esters (ie., butyl acetate, ethyl acetate), silicones (ie., cyclomethicones, dimethicones) as well as others known to those skilled in the art.
The polymers that are usable in the present invention are synthetic and/or natural polymers which are selectively soluble in at least one of the solvents listed hereinabove. The families of these polymers/co-polymers are preferably vinyl derivatives, acrylic derivatives, and styrene derivatives. Some specific materials utilizable in and suitable for use in the present invention that meet this description are as follows:
Vinyl Derivatives

Some biological polymers (natural) and their derivatives are: colloidon, glyceryl starch, hyaluronic acid, sodium hyaluronate, glycogen, hydrogenated honey, mixed mucopolysaccharides, nitrocellulose, sodium chondroitin sulfate, wheat starch.
The powder or color component of the composition is generally a dry particulate material which may be either colored or non-colored (i.e. white). Suitable powders are as follows: D&C Red No. 7 Calcium Lake, D&C Red No. 30 Lake, D&C Red No. 40 Aluminum Lake, D&C Yellow No. 10 Aluminum Lake, Ext. D&C Yellow No. 7 Aluminum Lake, FD&C Blue No. 1 Aluminum Lake, FD&C Red No. 3 Aluminum Lake, FD&C Red.
