United States Patent 3,384,547 MAKEUP COMPOSITIONS FDR THE THICKENING AND LENGTHENING 0F EYELASHES Maria A. Palmerio, New York, Julius Wetterhahn, Flushing, and Edward J. Masters, Roslyn, N.Y., assignors to Helena Rubinstein, Inc., New York, N.Y., a corporation of New York Filed Mar. 14, 1963, Ser. No. 265,197 Claims. (Cl. 167-85) The present invention relates to a makeup preparation for emphasizing and beautifying the eyelashes and for a dispenser including said preparation.

In accordance with certain features of the present invention, the makeup preparation comprises a mascara base containing a predetermined percentage of small fibers and constitutes a premixed mass in such form that small amounts may be removed therefrom by a pick-up device for direct application in premixed form to the eyelashes. Since the makeup mass from which the small amounts for eyelash application is premixed, the person applying the makeup is assured that the proper mixture is applied to the eyelash to produce the desired effects.

The application of the preparation described to the eyelashes, thickens and lengthens them, and results in definite emphasis of the eyelashes and greater beauty to the eye area.

If the mascara without fibers is applied to the eyelashes, and then the fibers alone are applied separately to the eyelashes, as for example, by a brush, there is no assurance that the fibers applied will be colored thoroughly by the mascara. It would, therefore, be necessary in such cases, in order to assure proper uniform coloration of the eyelashes, to employ fibers that are separately tinted black. Mascara contains innocuous coloring matter, such as carbon or oxide pigments, but fibers would have to be tinted with dyes, in order to assure full uniform coloration of the eyelashes when these fibers are applied to the eyelashes. Such dyes may be harmful in the sensitive regions of the eye.

The premixed preparation of the present invention contains the fibers in natural or white undyed state, and because the mascara and the fibers are thoroughly premixed under factory controlled formulations, the makeup preparation picked up by an applicator for application to the eyelashes will contain the fibers fully coated black by the mascara. The premixed preparation of the present invention, therefore, not only assures against the application of an eyelash makeup having disproportionate amounts of mascara or fibers, but also assures the use of makeup preparation free from ingredients having harmful effects.

In accordance with the present invention, it has been determined that optimum performance is dependent on the length of the fibers, and that it is desirable to employ fibers having two different lengths, the smaller lengths serving to thicken the eyelashes, and the longer ones serving to lengthen them. For example, it has been determined in accordance with the present invention, that when fibers of or less in length are used, the effect on the eyelashes is hardly different from that obtained using regular mascara. Fibers of in length incorporated in the mascara base result in a definite thickening of the eyelash. Also, there is a lengthening of the eyelash with fibers in length. It was determined in accordance with the present invention that the length of the eyelashes is increased effectively and desirably by the use of fibers of in length. When fibers of A3" in length or longer are used, the lengthening effect is enhanced, but the fibers do not adhere evenly on the eyelashes, and there is great difficulty incorporating such 3,384,547 Patented May 21, 1968 fibers uniformly into the mascara base. It has also been determined in accordance with the present invention that a mixture of fibers about long and about long results in an optimum balanced effect of both thickening and lengthening the eyelash.

To attain a desirable balance in the thickening and lengthening of the eyelashes, there should be employed a combination of fibers, in which the proportion of fibers ranges in weight from 50% to 80% and the proportion of fibers ranges in weight from 50% to 20%. Highly effective proportions would be about 75% by weight of fibers and about 25% by weight of fibers.

The concentration of the fibers in the mascara-fiber preparation may range from 2% to 8% by weight. An effective concentration for a specific example may be about 4%.

The denier of the fibers should range from 3 to 15. A suitable denier would be about 9.

The fibers, as far as certain features of the invention are concerned, can be of any suitable material, such as nylon, wool and cotton. However, rayon fiber has been found to be particularly suitable. Such fibers, for example, may be those classified as rayon fibersbright natural.

The fiber is undyed and is desirably white, so that no ingredients are present in the premixed preparation which may injure the eyes. The fiber, Whatever its color will assume the coloration of the mascara.

It has been found that the preparation containing a mixture of mascara and fibers, as described, is highly suitable for use in conjunction with a dispenser of the type carrying a grooved applicator rod and a reservoir of such preparation into which the rod dips. The preperation for use with such a dispenser should have a consistency ranging from a pasty state to a thick or viscous liquid state having sufficient viscosity to prevent the separation of the fibers in the reservoir and thereby to maintain the fibers uniformly dispersed throughout the mass of mascara.

For use with an applicator rod of the general type described, the mascara base consists essentially of an adhesive and a volatile solvent therefor which allows quick application of the mascara followed by quick drying, thereby permitting multiple application during a single makeup operation. Water based formulation can be used for the mascara, but the drying time for this formulation is longer.

The adhesive desirably is a wax, such as beeswax, ceresin, Japan vegetable wax or the like, beeswax being found to be especially suitable. The solvent for the Wax may be a volatile hydrocarbon, such as the oil of turpentine. The amount of this solvent would depend 'on its solvent properties and on the fiuidity desired for the final preparation. A suitable formulation for the mascara-fiber mixture may contain 40% to 70% by weight of volatile solvent and sufiicient water, as for example, about -l0% by weight, to form an emulsion using a suitable emulsifying agent, such as borax.

The coloring matter in the mascara is desirably carbon on a harmless pigment, such as oxide colors.

An example of a suitable formulation for the preparation of the present invention is as follows:

Beeswax 4 lbs.

Oil of turpentine 10 lbs. Borax 0 lbs. 2 ozs. Water '0 lbs. 2 ozs. Castor oil 0 lbs. 9 ozs. Rayon fibers 1/16", 9 denier 0 lbs. 3 ozs. Rayon fibers -1/ll, 9 denier 1 lb. 8 ozs.

Cosmetic colors (carbon or oxide colors), l-l% approx. q.s. to proper shade.

The castor oil in this formulation serves as an emollient, as a sheening or dressing agent, and as a means for adding to the body of the preparation.

In the specific formulation described, the preparation will be in the form of a thick viscous liquid short of being pasty.

The grooved applicator rod by which the preparation of the present invention may be dispensed and applied is desirably spirally V-threaded to form the groove-s, as shown in the drawings. The grooved applicator rod dips into the mascara-fiber preparation contained in a reservoir and when withdrawn from the reservoir, can be applied to the eyelashes by a stroking action causing the grooves containing the preparation to be carried along said eyelashes with the eyelashes in said grooves. This causes the eyelashes to pick up the mixture of mascara .and fibers and at the same time to be separated.

It has been determined in accordance with the present invention, that the grooved part of the applicator rod should have an outside diameter varying between .100 and #177 inch and should have between 32 and 52 threads per inch to perform satisfactorily with mascara-fiber mixture of the character described. When an applicator rod has more threads per inch than 52, the makeup application is too fine, taking longer to apply the makeup. When an application of less than 32 threads per inch is used, the application is coarse, resulting in matting and clinging together of the eyelashes. In a specific embodiment, the outside diameter of the grooved part of the applicator rod could be about 138" and the number of threads per inch could be 42. Also, in a specific embodiment, the included angle between thethreads may be 64.

The following drawings illustrate a form of dispenser of the grooved applicator rod type that may be used in conjunction with the mascara-fiber preparation of the present invention.

In these drawings:

FIG. 1 is a perspective showing a dispenser in closed position;

FIG. 2 is a perspective showing the grooved applicator rod withdrawn from the reservoir of the dispenser containing the mascara-fiber preparation; and

-FIG. 3 is a longitudinal section of the closed dispenser shown somewhat enlarged.

Referring to the drawings, the dispenser consists essentially of a reservoir 11 containing a preparation 12 which corresponds to the mixture of mascara and fibers described above and an applicator rod 13 of the general type referred to above extending into said reservoir for immersion in said mascara mixture and terminating in a handle '14 by which said rod may be pulled out of said reservoir and applied to the eyelashes. More specifically, these basic elements of the dispenser 10 may be embodied in a dispenser device, as shown in the drawings. In this illustrated embodiment of the invention, the reservoir 11 consists of an outer casing shell 15 and a lining 16 preferably made of aluminum or a plastic which will not react with the mascara and terminating short of the outer end of the outer shell, whereby said shell defines an end extension 17 beyond said lining. Seated against the end of the lining 16 is an annular metal washer 18 and over that is an annular washer 20 made of elastomeric material, such as'rubber or an elastic plastic. Holding the lining 16 and washers 18 and 20 permanently together is an annular bushing 22 with an enlarged inner end portion 23 extending into the extension 17 of said lining and secured to said extension, as for example, by a press-fit. This bushing 22 bears against the resilient washer 20 desirably with some pressure to place said washer under a little compression. Thus, the elements 1 6, 18, 20 and 22 are firmly secured to the outer casing shell 15 to form a permanent unit therewith.

The bushing 22 has an outer end portion 24 of reduced diameter externally threaded and extending beyond the outer end of the shell 15 to define a neck to which the handle 14 may be removably attached. The handle 14 comprises a hollow cap or casing 25 secured to the .applicator rod 13 by means of a bushing 26 extending fully into the end of said casing and fixedly secured thereto, as for example, by press-fitting. This bushing 26 is formed with a recess 27 to define an annular skirt 28 internally threaded for screw engagement with the externally threaded end portion 24 of the bushing 22 and has its head permanently secured to the outer end of the applicator rod 13 by rivetting, as shown, or by any other suit-able means. An annular washer 30 of elastomeric material, such as rubber, or elastic plastic, encircling the shank of the applicator rod '13 is l cated in the recess 27 of the bushing 26 and is seated against the head of the bushing 26-. The washer '30 is under 'sufi'icient pressure to be held permanently against the head of the bushing 26 even when the cap 25 is unscrewed from the bushing 22 or reservoir part of the dispenser, and is adapted to bear against the end of the bushing 22 with a sealing fit when the cap is screwed home to said bushing.

The diameter of the applicator rod 13 is slightly greater than the diameter of the hole in the elastic washer 20,

so that said washer serves to wipe the excess mascarafiber mixture as the rod is withdrawn from the reservoir 11 without oltering excessive resistance to this withdrawal of the rod. The inner end section 32 of the applicator rod 13 dipping into the mascara-fiber mixture 12 is equipped with circumferential grooves 33 which are desirably helical V threads constructed as described above.

In operation, when it is desired to apply makeup to the eyelashes, the cap 25 is unscrewed from the bushing 22 attached to the reservoir 11 and the applicator rod 13 is then withdrawn from the reservoir, as shown in FIG. 2. As the applicator rod 13 moves through the wiping washer 20, all the mascara-fiber mixture on the exterior surface thereof will be removed except that which is in the grooves 33. The applicator rod 13 may be applied to the eyelashes so that they enter the grooves 33 and pick up the mascarafiber mixture therein. This can be conveniently accomplished by holding the applicator rod 13 parallel to the eyelashes and stroking the eyelashes from the eyelid outwardly to the ends of the eyelashes. The threads on the applicator rod 13 will keep the eyelashes separated and prevent matting, and the fibers in the mascara-fiber mixture will thicken the eyelashes with fuzz-like realism and at the same time will lengthen them, so that the appearances around the regions of the eyes are emphasized and enhanced.

Although the mascara-fiber preparation described is in semi-plastic or thick liquid form for use in connection with a dispenser of the grooved applicator rod type, as far as certain aspects of the invention are concerned, the mixture preparation can be in the form of a solid cake and the applicator therefor can be in the form of a brush. The mascara base for sucha cake-like preparation could be of the type well known in the art for such preparations, and the fibers and their proportions would be substantially as indicated in connection with the more fluid type of preparation described above. With such cake formulation, the mascara base would consist essentially of an adhesive, such as beeswax, soap to permit the removal of the preparation by a wet brush and a pigment with possible adjuncts, such as glycerine. No volatile solvents would be used.
