The present disclosure relates generally to systems for applying cosmetic compositions to keratinous material, in particular to applicators containing a slit and associated cosmetic compositions for application to hair, eyebrows and/or eyelashes.
Cosmetic compositions for making up keratinous materials such as eyebrows and/or eyelashes (mascaras) typically are marketed in a system including a reservoir in which the composition is stored together with a brush for applying the composition to eyebrows and/or eyelashes. Application of such mascaras occurs by placing the brush into the reservoir, coating the brush with mascara, withdrawing the brush from the reservoir, and applying the mascara to eyebrows and/or eyelashes. This can be a problematic process.
More specifically, traditional mascara applicators typically include a slender brush having a cap on one end that provides a handle, which may be threaded upon the neck of a container with the brush located within the mascara. In operation, the cap on the end of the brush is unscrewed from the container neck with one hand, and the brush is removed bearing a supply of mascara on its bristles. The user may then stroke the mascara-laden bristles upon the eyelashes, and upon completion of the application replace the brush back with its bristles housed within the container and its supply of mascara. Such applicators are not as well-suited for a single hand operation and application.
Further, the shape and orientation of brush bristles of the applicator are normally fixed. Therefore, where the design of the brush applicator is well-suited for applying mascara to the lashes of one eye with one hand, they are inherently not as well suited for applying mascara with the same hand to the other eye. For instance, an applicator that has a generally cylindrical, peripheral surface of its brush bristles is better-suited for applying mascara to the central portion of the lashes than to the end portions. In contrast, where the applicator has a conical shape of bristles, with the apex of the conical mass located at the tip of the brush, the brush is well suited for applying with the right hand mascara to right eyelashes, while it is ill-suited for applying mascara to the left eye lashes unless a hand switch is made.
Additionally, for the above described mascara applicators, the user needs to frequently dip the brush in the container supply to secure more mascara on the bristles before further application. Such a frequent dip and apply process may lead to an uneven amount of mascara being transported to the brush bristles, which may result in an uneven application of the mascara.
The result of the above limitations of mascaras is that many consumers forego using mascaras, opting to avoid the often difficult application process.
Thus, there remains a need for improved cosmetic compositions for application to keratinous materials such as mascaras having improved application properties.
Accordingly, one aspect of the present invention is a care and/or makeup and/or treatment system for keratinous material which includes a cosmetic composition having good cosmetic properties such as, for example, long-wearing, easy to remove, possesses good anti-flaking properties and/or possess good anti-smudging properties, where the system allows easy application of the composition to keratinous material.
The present invention relates to a system for applying a cosmetic composition to a keratinous material comprising a cosmetic applicator and a cosmetic composition. The cosmetic applicator includes a container configured to store the cosmetic composition, an applicator head having a linear or non-linear orientation such as a curved, bent or conical shape with a proximal end and a distal end, and a slit along an axis of the applicator head, the distal end connected to the container. Preferably, the container is deformable and/or the applicator head is flocked with flocking extending on a portion of the applicator head, extending over a circumference of the applicator head or extending completely around the circumference of the applicator head, and covering or exposing the slit. Preferably, the cosmetic composition is a mascara and/or the keratinous material is hair, eyebrows and/or eyelashes.

The foregoing paragraphs have been provided by way of general introduction, and are not intended to limit the scope of the following claims. The described embodiments, together with further advantages, will be best understood by reference to the following detailed description taken in conjunction with the accompanying drawings.
The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate one or more embodiments and, together with the description, explain these embodiments. The accompanying drawings have not necessarily been drawn to scale. Any values dimensions illustrated in the accompanying graphs and figures are for illustration purposes only and may or may not represent actual or preferred values or dimensions. Where applicable, some or all features may not be illustrated to assist in the description of underlying features. In the drawings:
In the following description of the invention and the claims appended hereto, it is to be understood that the terms used have their ordinary and accustomed meanings in the art, unless otherwise specified.
“About” as used herein means within 10% of the indicated number (e.g. “about 10%” means 9%-11% and “about 2%” means 1.8%-2.2%).
“A” or “an” as used herein means “at least one.”
As used herein, all ranges provided are meant to include every specific range within, and combination of subranges between, the given ranges. Thus, a range from 1-5, includes specifically 1, 2, 3, 4 and 5, as well as subranges such as and 2-5, 3-5, 2-3, 2-4, 1-4, etc.
“Film former”, “film-forming polymer” or “film forming agent” or “co-film former” as used herein means a polymer or resin that leaves a film on the substrate to which it is applied, for example, after a solvent accompanying the film former has evaporated, absorbed into and/ or dissipated on the substrate.
“Wax” as used herein is a lipophilic fatty compound that is solid at ambient temperature (25° C.) and changes from the solid to the liquid state reversibly, having a melting temperature of more than 30° C. and, for example, more than 45° C., which can be as high as 150° C., a hardness of more than 0.5 MPa at ambient temperature, and an anisotropic crystalline organization in the solid state.
“Free” or “devoid” of as it is used herein means that while it is preferred that no amount of the specific component be present in the composition, it is possible to have very small amounts of it in the compositions of the invention provided that these amounts do not materially affect at least one, preferably most, of the advantageous properties of the compositions of the invention. Thus, for example, “free of solvents” means that non-aqueous solvents are preferably omitted (that is 0% by weight), but can be present in the composition at an amount of less than about 0.25% by weight, typically less than about 0.1% by weight, typically less than about 0.05% by weight, based on the total weight of the composition.
“Makeup Result” as used herein, refers to compositions where color remains the same or substantially the same as at the time of application, as viewed by the naked eye, after an extended period of time. “Makeup Result” may be evaluated by evaluating long wear properties by any method known in the art for evaluating such properties. For example, long wear may be evaluated by a test involving the application of a composition to keratin materials such as eyelashes and evaluating the color of the composition after an extended period of time. For example, the color of a composition may be evaluated immediately following application to keratin materials such as eyelashes and these characteristics may then be re-evaluated and compared after a certain amount of time. Further, these characteristics may be evaluated with respect to other compositions, such as commercially available compositions.
“Making up” as used herein means to provide decoration (for example, color) to keratin materials such as the eyelashes.
“Protecting” as used herein means to inhibit damage to keratin materials such as the eyelashes by providing a protective layer on the keratin materials.
“Substituted” as used herein, means comprising at least one substituent. Non-limiting examples of substituents for substitution include atoms, such as oxygen atoms and nitrogen atoms, as well as functional groups, such as hydroxyl groups, ether groups, alkoxy groups, acyloxyalkyl groups, oxyalkylene groups, polyoxyalkylene groups, carboxylic acid groups, amine groups, acylamino groups, amide groups, halogen containing groups, ester groups, thiol groups, sulphonate groups, thiosulphate groups, siloxane groups, and polysiloxane groups. The substituent(s) may be further substituted.
“Water resistance” as used herein, means resistance of a material (substance) to the penetration of water, which may cause degradation of that material. The method implemented if assessment of this invention is further disclosed.
“Transfer resistance” as used herein refers to the quality exhibited by compositions that are not readily removed by contact with another material, such as, for example, a glass, an item of clothing or the skin, for example, when eating or drinking. Transfer resistance may be evaluated by any method known in the art for evaluating such. For example, transfer resistance of a composition may be evaluated by a “kiss” test. The “kiss” test may involve application of the composition to human keratin material such as hair, skin or lips followed by rubbing a material, for example, a sheet of paper, against the hair, skin or lips after expiration of a certain amount of time following application, such as 2 minutes after application. Similarly, transfer resistance of a composition may be evaluated by the amount of product transferred from a wearer to any other substrate, such as transfer from the hair, skin or lips of an individual to a collar when putting on clothing after the expiration of a certain amount of time following application of the composition to the hair, skin or lips. The amount of composition transferred to the substrate (e.g., collar, or paper) may then be evaluated and compared. For example, a composition may be transfer resistant if a majority of the product is left on the wearer's hair, skin or lips. Further, the amount transferred may be compared with that transferred by other compositions, such as commercially available compositions. In a preferred embodiment of the present invention, little or no composition is transferred to the substrate from the hair, skin or lips.
The compositions and methods of the present invention can comprise, consist of, or consist essentially of the essential elements and limitations of the invention described herein, as well as any additional or optional ingredients, components, or limitations described herein or otherwise useful.
Referred to herein are trade names for materials including, but not limited to polymers and optional components. The inventors herein do not intend to be limited by materials described and referenced by a certain trade name. Equivalent materials (e.g., those obtained from a different source under a different name or catalog (reference) number) to those referenced by trade name may be substituted and utilized in the methods described and claimed herein.
All percentages and ratios are calculated by weight unless otherwise indicated. All percentages are calculated based on the total weight of a composition unless otherwise indicated. All component or composition levels are in reference to the active level of that component or composition, and are exclusive of impurities, for example, residual solvents or by-products, which may be present in commercially available sources.
Furthermore, where a range of values is provided, it is to be understood that each intervening value between an upper and lower limit of the range and any other stated or intervening value in that stated range is encompassed within the disclosure. Where the stated range includes upper and lower limits, ranges excluding either of those limits are also included.
The following disclosure is to aid the reader in understanding the present invention, but it is not intended to vary or otherwise limit the meaning of the invention or terms/phrases describing the invention.

The applicator head 101 (or 301) discharges the cosmetic composition such as mascara on to the flocked brush 105 (or 305) via a slit. According to preferred embodiments of the present invention, slit can be of any geometry such as, for example, amorphous, rectangular, oval, triangular, etc. The slit can be positioned anywhere along the length of the applicator head 101 (or 301) covered with the flocked brush 105 (or 305), and can be parallel, perpendicular or skew to any axis of the applicator head. Preferably, the slit has a length which is at least about 40% of the length of the applicator head, preferably at least about 50% of the length of the applicator head, and preferably at least about 60% of the length of the applicator head.
Preferably, the slit has a width smaller than 2 mm, preferably smaller than 1.7 mm, preferably smaller than 1.5 mm while preferably being larger than 0.3 mm, preferably larger than 0.5 mm, and preferably larger than 0.7 mm, including all ranges and subranges therebetween such as, for example, 0.7 mm to 1.5 mm, etc.
The slit SIA of the applicator head S401 can have a length Ls1 and width w1. For example, the width w1 of the slit S1A of the head S401 can be approximately 1 mm. Similarly, the slit S1B of the applicator head S403 can have a length Ls3 and width w3. For example, the width w3 of the slit S1B of the head S403 can be approximately 1.4 mm. The slit S1C of the applicator head S404 can have a length Ls4 and width w4. For example, the width w4 of the slit S1C of the head S404 can be approximately 0.7 mm.
The length of the slit can extend from the end portion 101a (or 301a) of the applicator head 101 (or 301) up to the proximal end and/or the distal end. For example, the length of the slit can be between about 20% to 80% of the length of the length of the applicator head 101, preferably 30% to 70%, preferably 33% to 50%, including all ranges and subranges therebetween.
The slit controls an amount of mascara discharge on the flocked brush 105 (or 305).
The amount of cosmetic composition such as mascara discharged can be a function of, among other things, the dimensions of the slit and cosmetic composition (mascara) properties including viscosity, consistency, critical strain, force applied to the tube 103 (or 303), and flock material. An optimum amount of mascara should be discharged to provide deposit of product on the flocked brush 105 (or 305), so that the mascara or cosmetic composition can be applied to a surface such as user's hair, eyelashes or eyebrows.

Preparation of O/W Emulsions
Water was heated to 60-70° C. with agitation using a large chopping blade (100 rpm).
Water was charged with pigments, preservatives, water soluble thickeners, water soluble emulsifiers, and plasticizers and mixed with a large rotor-stator homogenizer at 500-900 rpm until pigments dispersed (approx. 1 hr).
Oils, liquid fats, oil soluble emulsifiers and film formers were melted at 70-90 degrees C. and added to water phase using large rotor-stator homogenizer at 900-1200 rpm and emulsified for 30 minutes at 70-80 degrees C.
Once emulsified the composition was cooled to 50-60° C.
Temperature sensitive latex and silicone film former dispersions were then added and mixed for 20 minutes (1200 rpm).
The homogenizer was switched to slow sweeper blade and cooled to <30° C.
Preparation of Anhydrous Compositions
Weighed Phase A (malate, octyldodecanol, resin, trimelliate, benzoate, and cinnamate) oils and heated to 98-100° C. with a Raynieri equipped with a homogenizing blade at 900 rpm.
Once temperature reached, added dextrin palmitate. Lowered temperature to 90° C.
In a separate beaker mixed preservatives and sticky polymers (polybutenes) followed by the pigments, pearls and fillers.
Cooled to room temperature and dropped the batch.
Compositions in Example 1 were tested for viscosity, complex modulus (G*) and critical strain (γc) properties. The extrusion force associated with applying compositions in example 1 via applicators of the present invention was also determined. Results for identified compositions are identified below.
Viscosity. Method A. The viscosity of the formulas were measured at 25° C. with a Brookfield DVIIT viscometer in the absence of the guard leg, using the spindle and rpm listed in Table 4 (hereinafter, “Method A”). The reported viscosity is that shown is that after 10 minutes after switching on the rotation of the spindle (when a constant torque is read) and the values are reported in cps.
Consistency and critical strain. Method B. Complex modulus (G*) and critical strain (γc) of inventive compositions determined from a strain sweep experiment at 20° C. using a TA instrument AR-G2 or AR-DH2 rheometer and a 40 mm stainless steel 2° cone or crosshatch probe from 0.01 to 1000% strain at 1 rad/sec angular frequency.
Extrusion Force. Tubes were filled with 15 grams of bulk and sealed. Tubes placed on balance on their side and balance was tarred. Tube pressed with hand and the amount of force required to dispense the product was recorded. The result of dispensing was also recorded. The result of dispense was recorded as tubes, uneven mountain, tubes that wet evenly along the applicator, even applicator wetting.
Rheologic properties of compositions in example 1 (n=2) determined according to Method B are set forth below.
Viscosities of compositions in example 1 determined according to Method A above are set forth below.
