Abstract

Disclosed are methods for applying mascara compositions to eyelashes, comprising applying washable mascara followed by applying waterproof mascara. Mascara products and systems, and packages containing the products are also disclosed.

Description

BACKGROUND OF THE INVENTION

Mascaras are commonly prepared as wax-based formulations according to two types. Washable mascaras, which can be removed with soap and water, generally come in the form of an emulsion of waxes in water such as creams, as well as in gels. Waterproof mascaras, which require use of oils for removal, generally come in the form of dispersions of waxes in organic solvents.
Each type of mascara has advantages and disadvantages. Application of washable mascaras enhances volume; that is, they thicken the eyelashes. However, they are prone to smudge such as when rubbed. In addition, they are not resistant to water. Waterproof mascaras on the other hand are relatively water-resistant and are less likely to run or smudge. However, unlike washable mascaras, they cannot be removed simply with soap and water. They require the use of organic based cleansing agents such as mineral oil.
There have been many developments in cosmetics for application to eyelashes and eyebrows aimed at improvement one or more of these properties, or other properties such as ease of application, homogeneity, comfort and good hold. For example, mixtures of waxes have been used to combine properties such as film hardness and adhesion to the lash. See, e.g., WO-A-95/15741. U.S. Pat. No. 6,464,967 teaches the use of specific polyolefin waxes in mascara compositions. U.S. Pat. No. 6,375,941 is directed to a wax-free mascara composition that contains film-forming polyurethane. U.S. Pat. No. 5,879,668 teaches waterproof mascara in the form of a water-in-oil (W/O) emulsion in which water (the disperse phase) is emulsified in oil (the continuous phase). The oil is preferably a C₁₀-C₁₄saturated, linear or branched, hydrocarbon, more preferably a C₁₁-C₁₃saturated, linear or branched, hydrocarbon, more preferably a branched C₁₂saturated hydrocarbon such as isododecane. Of course, mixtures of these hydrocarbons may be used and often are provided by commercial “technical” grades of these hydrocarbons. The emulsions are contain solid particles, preferably pigment particles and preferably at least two different types of surfactants, one being an a “oil surfactant” having a hydrophobic-lipophobic balance (HLB) of from 3-4.5, the other being a “water surfactant” having an HLB of 5.5-7.5.

SUMMARY OF THE INVENTION

A first aspect of the present invention is directed to a method of applying mascara to eyelashes, comprising: a) applying a washable mascara composition to the eyelashes; followed by b) applying a waterproof mascara composition to the eyelashes. Eyelashes treated in accordance with the method of the present invention—which includes real and false eyelashes—may have enhanced thickness and exhibit greater water- and smudge-resistance, and ease of removal, compared to typical waterproof and washable mascaras when used alone.
A second aspect of the present invention is directed to a product or system for applying mascara to eyelashes, comprising a) a first reservoir that contains a washable mascara composition, b) a second reservoir that contains a waterproof mascara composition, and c) at least one applicator comprising first and second applicator members for applying the respective mascara compositions.
A third aspect of the present invention is directed to a package containing a system for applying mascara to eyelashes, comprising a) a first reservoir that contains a washable mascara composition, b) a second reservoir that contains a waterproof mascara composition, and c) at least one applicator comprising first and second applicator elements or members for applying the respective mascara compositions.

DETAILED DESCRIPTION

Washable mascaras can be removed simply by use of soap and water. Waterproof mascaras are not as easily removable, and require use of oil such as mineral oil. Washable or aqueous mascaras generally come in the form of an emulsion of waxes in water (sometimes referred to as cream mascaras), or gels, whereas waterproof mascaras generally come in the form of dispersions of a fatty phase that includes one or more waxes in organic solvents (which when lacking water are sometimes referred to as anhydrous mascaras), or water-in-oil emulsions (see, e.g., U.S. Pat. No. 5,879,668). Washable mascaras and waterproof mascaras may contain many similar ingredients (e.g., waxes and film-forming polymers), the main differences between them being in the relative amounts of the ingredients, particularly water. Generally, water content of washable mascaras ranges from about 20 to about 80% by weight, and preferably from about 30 to about 60% by weight of the mascara composition. In contrast, water content of waterproof mascaras generally ranges from about 0 to about 60% by weight, and preferably from about 0 to about 35% by weight of the mascara composition. One or more water-miscible solvents may also be present in either type of mascara. Examples include lower monoalcohols containing from 1 to 5 carbon atoms, C₃-C₄ketones and C₃-C₄aldehydes. A preferred water-miscible solvent is ethanol. The content of water-miscible solvents generally ranges from about 0.1% to about 15% by weight, and preferably from about 1% to about 8% by weight relative to the total weight of the mascara composition.
Washable and waterproof mascaras usually have different viscosities. Viscosity is important from the standpoints of fast and easy application of the composition, as well as uniform coating over the entire length of the eyelashes. Generally, viscosity of washable mascaras ranges from about 10 to about 60 pascal seconds (Pa*s), and preferably from about 20 to about 40 Pa*s, whereas viscosity of waterproof mascaras ranges from about 10 to about 70 Pa*s, and preferably from about 10 to about 40 Pa*s. Viscosity is measured at 25° C. with a Rheomat RM 180 viscometer fitted with a No. 4 rotor, wherein the measurement is carried out after spinning the rotor for 10 minutes (after which time stabilization of the viscosity and of the rotor spin speed are observed), at a shear rate of 200 s^−1.
Viscosity may be adjusted by adding a thickener. Representative examples include cellulose-based thickeners, for example, water-soluble cellulose-based thickeners, such as hydroxyethylcellulose, methylcellulose, hydroxypropylcellulose and carboxymethylcellulose. Among these thickeners, specific examples include the gums sold under the name “Cellosize QP 4400 H” by the company Amerchol, guar gum, in particular, those sold under the name Vidogum GH 175 by the company Unipectine and under the name Jaguar C by the company Meyhall, the quaternized guar gum sold under the name “Jaguar C-13-S” by the company Meyhall, nonionic guar gums comprising C₁-C₆hydroxyalkyl groups, e.g., hydroxymethyl, hydroxyethyl, hydroxypropyl and hydroxybutyl groups. Such guar gums are sold, in particular, under the trade names Jaguar HP8, Jaguar HP60, Jaguar HP120 and Jaguar HP 105 by the company Meyhall, or under the name Galactasol 40H4FD2 by the company Aqualon. Other examples of thickeners include xanthan gum, carob gum, scleroglucan gum, gellan gum, rhamsan gum and karaya gum, alginates, maltodextrin, polysaccharide resins such as starch and its derivatives, hyaluronic acid and its salts, clays, and, in particular, montmorillonites, hectorites and laponites, crosslinked polyacrylic acids, such as the “Carbopol” products from the company Goodrich, the polyglyceryl (meth)acrylate polymers sold under the names “Hispagel” or “Lubragel” by the companies Hispano Quimica or Guardian, polyvinylpyrrolidone (PVP), polyvinyl alcohol, crosslinked acrylamide polymers and copolymers, such as those sold under the names “PAS 5161” or “Bozepol C” by the company Hoechst, “Sepigel 305” by the company SEPPIC, crosslinked methacryloyloxyethyltrimethylammonium chloride homopolymers sold under the name “Salcare SC95” by the company Allied Colloid, and associative polymers and, in particular, associative polyurethanes.
The mascaras suitable for use in the present invention typically contain a thickener in an effective amount for the composition to have the viscosity as defined above. The thickener content can range, for example, from 0.1% to 10% by weight relative to the total weight of the composition, and preferably from 0.5% to 5% by weight.
A variety of waxes may be present in the mascaras of the present invention, including waxes of animal origin, waxes of plant origin, waxes of mineral origin and waxes of synthetic origin. Examples of waxes of animal origin include beeswaxes, lanolin waxes and Chinese insect waxes. Examples of waxes of plant origin include rice waxes, carnauba wax, candellila wax and ouricurry wax, cork fibre waxes, sugar cane waxes, Japan waxes, sumach wax and cotton wax. Examples of waxes of mineral origin include paraffins, microcrystalline waxes, montan waxes and ozokerites. Examples of waxes of synthetic origin include polyolefin waxes, e.g., polyethylene waxes, waxes obtained by Fischer-Tropsch synthesis, waxy copolymers and their esters, and silicone waxes.
Alternatively, hydrogenated oils of animal or plant origin may be used. Examples include hydrogenated jojoba waxes and hydrogenated oils which are obtained by catalytic hydrogenation of fats composed of a C₈-C₃₂linear or nonlinear fatty chain, hydrogenated sunflower oil, hydrogenated castor oil, hydrogenated copra oil, hydrogenated lanolin and hydrogenated palm oils. The waxes are preferably solid and rigid at temperatures below 50° C.
Generally, wax content of washable mascaras ranges from about 0 to about 50% by weight, and preferably from about 10 to about 45% by weight of the mascara composition. Wax content of waterproof mascaras generally ranges from about 0 to about 40% by weight, and preferably from about 5 to about 35% by weight of the mascara composition.
The composition according to the invention may additionally comprise a film-forming polymer which can be solubilized and/or in the form of particles in dispersion in the aqueous phase. The film-forming polymer can be selected from keratin derivatives, such as keratin hydrolysates and sulphonic keratins; anionic, cationic, amphoteric or nonionic derivatives of chitin or chitosan; cellulose derivatives such as hydroxyethylcellulose, hydropropylcellulose, methylcellulose, ethylhydroxyethylcellulose, carboxymethylcellulose, and quaternized derivatives of cellulose; acrylic polymers or copolymers, such as polyacrylates or polymethacrylates; polyvinylpyrrolidones (PVP) and vinyl copolymers, such as methyl vinyl ether-maleic anhydride copolymers, or vinyl acetate-crotonic acid copolymer; water-dispersible anionic polyesteramide and/or polyester polymers comprising monomers bearing a functional group—SO₃M, in which M represents a hydrogen atom, an ammonium ion NH₄ ⁺ or a metal ion, such as, for example, an Na⁺, Li⁺, K⁺, Mg²⁺, Ca²⁺, Cu²⁺, Fe²⁺ or Fe³⁺ ion. Specific examples of the polymers described in U.S. Pat. Nos. 3,734,874, 4,233,196 and 4,304,901. Polyurethane polymers, especially anionic, cationic, nonionic or amphoteric polyurethanes, acrylic polyurethanes, polyvinylpyrrolidone polyurethanes, polyester polyurethanes, polyether polyurethanes, polyureas, polyurea/polyurethanes, and mixtures thereof; and polymers of natural origin, modified if desired, such as gum arabic, guar gum, xanthan derivatives, karaya gum; alginates and carragheenates; glycoaminoglycans, hyaluronic acid and its derivatives; shellac, sandarac gum, dammars, elemis and copals, are also useful. Preferred film-forming polymers include acrylate copolymers, PVP, silicone resins (e.g., Polysilicone 8) and vinyl copolymers.
The film-forming polymer can be present in the mascara compositions in an amount of dry matter generally ranging from about 0.1% to about 20% by weight relative to the total weight of the mascara composition.
The mascara compositions of the invention may contain emulsifying surfactants. Surfactants can be selected from amphoteric, anionic or nonionic surfactants. See, e.g., Encyclopedia of Chemical Technology, KIRK-OTHMER, volume 22, pp. 333-432, 3rd edition, 1979, Wiley, for the definition of the properties and (emulsifying) functions of the surfactants, in particular pp. 347-377 of this publication regarding anionic and nonionic surfactants. Examples of surfactants useful in the mascara compositions of the invention are include as nonionic surfactants, fatty acids, fatty alcohols, polyethoxylated fatty alcohols or polyglycerolated fatty alcohols, such as polyethoxylated stearyl alcohols or cetylstearyl alcohols, esters of fatty acid and sucrose, and glucose alkyl esters, in particular polyoxyethylenated C₁-C₆alkyl glucose fatty esters, and as anionic surfactants, C₁₆-C₃₀fatty acids neutralized by amines, ammonia or the alkali metal salts thereof. Examples of amphoteric surfactants include betaines, sultaines, hydroxysultaines, alkyl amphodiacetates, alkyl amphodipropionates, and imidazolines, or salts thereof. Other fatty acid condensates such as those formed with amino acids, proteins, and the like are suitable as well. Specific examples include cocamphodipropionate, e.g., Miranol C2M-SF (disodium cocamphodipropionate), in its salt-free form, available from Rhone-Poulenc, and Crosultaine C-50 (cocamidopropyl hydroxysultaine), available from Croda.
In washable mascaras, surfactants are selected in order to obtain an oil-in-water emulsion. Preferred examples include triethanolamine and stearic acid. In waterproof mascaras, surfactants are often used to facilitate dispersion of pigments. Preferred examples include lecithins. Lecithins are mixtures of phospholipids, i.e., of diglycerides of fatty acids linked to an ester of phosphoric acid. Preferably, lecithins are diglycerides of stearic, palmitic, and oleic acids linked to the choline ester of phosphoric acid. Lecithin is usually defined either as pure phosphatidyl cholines or as crude mixtures of phospholipids which include phosphatidyl choline, phosphatidyl serine, phosphatidyl ethanolamine, phosphatidyl inositol, other phospholipids, and a variety of other compounds such as fatty acids, triglycerides, sterols, carbohydrates, and glycolipids. See, e.g., U.S. Pat. Nos. 6,015,574 and 6,221,389. Lecithins may also be present in washable mascaras. Surfactants are generally present in amounts ranging from about 2 to about 30% by weight, and preferably from about 5% to about 15% by weight, relative to the total weight of the mascara composition.
The composition of the invention may additionally comprise ingredients that are commonly used in cosmetics, such as plasticizers, coalescence agents, fillers, dyestuffs, such as pigments or dyes, preserving agents, oils, cosmetic agents, such as moisturizers and anti-UV agents vitamins, trace elements, softeners, sequestrants, perfumes, oils, silicones, proteins, ceramides, cohesion agents, and the basifying or acidifying agents that are commonly employed in the cosmetics field.
In terms of fillers, silica is particularly useful to obtain a thicker make-up effect on the eyelashes. Starches such as rice starch, talc and polytetrafluoroethylene are highly compatible with aqueous medium and allow a smooth, shiny film of make-up to be obtained. Fillers are generally present in the mascara compositions in an amount of about 0.1% to about 6% by weight relative to the total weight of the mascara composition.
In addition to the foregoing teachings, examples of specific washable and waterproof mascara compositions are legion in the prior art. See, e.g., U.S. Pat. No. 6,264,933 for examples of waterproof mascaras, and U.S. Pat. No. 5,985,258 for examples of washable mascaras.
The methods of the present are practiced simply by applying to the eyelashes the washable mascara, followed by applying the waterproof mascara. The waterproof mascara may be applied immediately after application, but generally anytime from about 30 seconds to about 10 minutes after application of the washable mascara.
With reference to FIGS. 1-3, the mascara compositions of the invention may be provided in a mascara product or system comprising two reservoirs, each of which contains one of the mascara compositions, and applicators for applying each of the compositions to the eyelashes. This mascara product or system may be conveniently packaged in a variety of forms. As best shown in FIG. 1, one example of such preferred packaging includes a blister pack 10. The reservoirs 14 and 16 are housed in the blister pack 10, which comprises translucent plastic material (not shown) attached to a cardboard substrate backing 12. The backing may be generally rectangular in shape. Any shape that is capable of preventing any direct handling of the products by customers is contemplated and within the scope of the present invention. See, e.g., U.S. Pat. No. 6,378,727.
Each reservoir 14 and 16 is positioned within the blister pack 10, preferably in a side-by-side manner. Each reservoir includes corresponding applicator portions 18 and 20, which are discussed below in detail.
The reservoirs typically are provided with an opening 15, 17 that accommodates a liquid-removal (or applicator) system. As best seen in FIG. 2, the applicator portions 18, 20 typically comprise a rod 22, 24 equipped at a first end with an applicator member 26, 28 such as a brush, and at a second end with a handle component 30, 32 that acts as both a means for manipulating the applicator by the user, and as a cap for closing the reservoir, preferably in a leak-tight manner (e.g., the handle component itself is configured to close the reservoir).
The applicator member 26, 28 preferably comprises bristles 34, 36 arranged radially around a twisted core 38, 40, such as a metal core. The brush can be of varied shapes and can comprise cutout sections. Mascara brushes are described, for example, in French Patent Application No. FR-A-2,607,373 and European Patent Application Nos. EP-A-611,170, EP-A-811,336, EP-A-811,337 and EP-A-842,620.
The respective applicator members 26, 28 may be the same or different. In some embodiments, they are different. For example, application of the washable mascara may be facilitated with a relatively full and soft brush 34. An example of such a brush is described in U.S. Pat. No. 4,887,622. The disclosed brushes include a central core formed by a twisted iron wire holding a helical array of radial bristles in a regular manner characterized by the fact that the bristles have a diameter between about 0.10 and about 0.25 millimeters (mm), and the number of bristles per turn being between about 10 and about 40.
A preferred example of an applicator member 28 for applying waterproof mascara is described in U.S. Pat. No. 4,993,440. The brushes disclosed in this patent contain a central elongate core around which are implanted bristles disposed in a substantially radial fashion and regularly distributed. Each bristle 36 of at least one portion of the brush comprises on its surface at least one capillary channel (not shown) extending substantially from its base as far as its tip. Preferably, all the bristles of the brush have capillary channels. The brush is evenly charged and a homogeneous distribution of the mascara on the eyelashes is achieved. Further, the systems and packages of the present invention may further contain indicia such as directions or instructions (e.g., printed information) for using the mascara compositions.
Alternate embodiments of mascara systems are shown in FIGS. 3A and 3B. In FIG. 3A, the reservoirs 14 and 16 are integral with each other, e.g., their respective bottom or side surfaces are fastened together in some manner. In another alternate embodiment shown in FIG. 3B, one applicator 50 is provided, which contains a single handle component 18′ and two stems 22, 24 oppositely opposed from the handle component, wherein each stem has an applicator member 26, 28 at its opposite end. The handling component contains a cap configured to close each of the reservoirs, preferably in a leak-tight manner.
The present invention is further described in terms of the following non-limiting examples. Unless otherwise indicated, all parts and percentages are on a weight-by-weight basis.

To prepare the washable mascara, the PVP/VA was added to water, using a homogenizer to disperse and heat to 60° C. Premixed butylene glycol and hydroxyethylecellulose were added to the dispersion. Upon dispersion, methylparaben, disodium EDTA, triethanolamine, simethicone, and polysaccharide resin respectively, were added. Upon achieving a uniform dispersion, iron oxide was added. Polymethyl methacrylate isopropyl titanium triisostearate and Nylon-12 were added sequentially with milling until the mixture was well dispersed. The dispersion was heated to 85° C. to 90° C. Phase B ingredients were mixed separately and then heated to 85° C. to 90° C. Using a homogenizer, phase B was added to phase A, followed by emulsifying for 15 minutes. After emulsification was complete, the mixture was transferred to sweep mixing and air-cooled to 60° C. Premixed phase C was added slowly. Once uniform, premade-premixed phase D was added slowly at 55° C.
To prepare phase D, disodium cocoamphodipropionate, isoceteth-20 and simethicone were heated to 70° C. to 75° C. Once uniform, Lecithin was added while mixing at high speed using propeller mixer, until dispersed. Water was added at 70° C. to 75° C. while maintaining temperature at 70° C. to 75° C., and mixing until uniform (which took approximately 10 minutes). Methylparaben, propylparaben and disodium EDTA were added, and once dispersed, octylacrylamide/acrylates/butylaminoethyl methacrylate copolymer was added slowly to avoid lumping. These ingredients were mixed approximately 2 hours, while maintaining the temperature at 70° C. to 75° C., and then were cooled to 45° C.
Once uniform, phase E was added at 45° C. slowly enough to avoid coagulation, followed by mixing until uniform. Premixed phases F, G, and H were added at 40° C., followed by cooling to 30° C. to 32° C.

To prepare the waterproof mascara, phase A ingredients were added together and homogenized until dispersed at room temperature. Phase B ingredients were added, and homogenized until uniform, followed by addition of phase C and homogenized until dispersed. Once uniformly dispersed, phase D and E ingredients were added (at this point batch will become very heavy). The resultant dispersion was heated to 65° C. to 70° C. Phase F was prepared and heated to 90° C. to 95° C., and then added to the dispersion, followed by the addition of phase G. Homogenization was continued for 30 minutes, while maintaining the temperature at 65° C. to 70° C. Phase H was prepared and added to the dispersion, and then homogenized until uniform. Pre-made phase I was added; the dispersion was cooled to 45° C. using sweep mixing; and pre-mixed phase J was added, followed by cooling to 30° C. to 32° C.
Phase I was prepared by heating disodium cocoamphodipropionate, isoceteth-20 and simethicone to 70° C. to 75° C. Once uniform, lecithin was added while mixing at high speed using propeller mixer, until dispersed. Water was added at 70° C. to 75° C. while maintaining temperature at 70° C. to 75° C., and mixing until uniform (which took approximately 10 minutes). Methylparaben, propylparaben and disodium EDTA were added, and once dispersed, octylacrylamide/acrylates/butylaminoethyl methacrylate copolymer was added slowly to avoid lumping. These ingredients were mixed approximately 2 hours, while maintaining the temperature at 70° C. to 75° C., and then were cooled to 45° C.

EXAMPLE 3

Evaluation of Performance
A panel study was conducted in which the washable mascara described in example 1 was applied to the eyelashes of (one/two eye/eyes) of 6 panelists, followed by the application of the waterproof mascara described in example 2. Many application attributes were evaluated, including overall wear (judged in terms of hours), and smudging/smearing, ease of application, speed of build-up, length of lashes, thickening of lashes, amount of curl, amount of spiking, amount of flaking, homogeneity of application (i.e., amount of balls or globs on lashes), softness, wetness (or lack of dryness) of appearance, time for drying, comfort, overall appearance and ease of removal. The results shown in FIG. 4 were on the basis of an evaluation conducted immediately after application. The results shown in FIG. 5 were on the basis of an evaluation conducted 4 hours after application. They show that the mascara system of the present invention was judged very favorably from all of these application attributes.
