[0002] Many lipstick compositions contain animal-derived ingredients or beeswax to achieve a desired texture. Due to growing concerns about how these ingredients may be obtained, many customers prefer to avoid cosmetics containing these ingredients and instead opt for products that do not use these ingredients. However, without these ingredients (especially beeswax), it can be difficult to achieve a creamy and desirable texture in a lipstick composition.

[0010] The present invention relates to lipstick compositions comprising at least one natural oil, at least one fatty alcohol wax and particles of at least one filler. Preferably, the lipstick compositions contain a minimal amount of ingredients of animal origin and / or beeswax, or are free of such ingredients. Preferably, the compositions are anhydrous and in the form of a stick.

[0011] The present invention also relates to colored lipstick compositions comprising at least one coloring agent, at least one natural oil, at least one fatty alcohol wax and particles of at least one filler. Preferably, the lipstick compositions contain a minimal amount of ingredients of animal origin and / or, or are free of such ingredients. Preferably, the compositions are anhydrous and are in the form of a stick.

[0012] The present invention also relates to methods of treating, caring for, improving the appearance of and / or making up the lips by applying the compositions of the present invention to the lips in an amount sufficient to treat, care for, improve the appearance of and / or make up the lips.

[0013] It is understood that the foregoing general description and the following detailed description are only exemplary and explanatory, and are not restrictive of the invention. DETAILED DESCRIPTION OF THE INVENTION

[0014] As used herein, the term "at least one" means one or more and therefore includes individual components as well as mixtures / combinations.

[0015] “Film former” or “film-forming agent” as used herein means a polymer or a 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.

[0016] "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, clothing or skin. Transfer resistance may be evaluated by any method known in the art for evaluating it. For example, the transfer resistance of a composition may be evaluated by a "kiss" test or a material transfer test. This test may involve applying the composition to the lips, followed by rubbing a material, for example, a sheet of paper or a cotton ball, against the lips after a certain time has elapsed after application, for example, 2 minutes after application.Similarly, the transfer resistance of a composition can be evaluated by the amount of product transferred from a wearer to any other substrate, such as the transfer from an individual's lips to a garment when donning the garment after a certain time has elapsed after the composition is applied to the lips. The amount of composition transferred to the substrate (e.g., the garment, paper, or cotton ball) can then be evaluated and compared. For example, a composition may be transfer resistant if a majority of the product remains on the wearer's lips. Further, the amount transferred can be compared to that transferred by other compositions, such as commercially available compositions. In a preferred embodiment of the present invention, little or no composition is transferred from the lips to the substrate.

[0017] “Long-lasting” compositions, as used herein, refer to compositions whose color remains the same or substantially the same as at the time of application, as seen with the naked eye, after an extended period of time. Long-lasting properties may be evaluated by any method known in the art for evaluating such properties. For example, long-lasting may be evaluated by a test involving application of a composition to the lips and evaluation of the color of the composition after an extended period of time. For example, the color of a composition may be evaluated immediately after its application to the lips and these characteristics may then be re-evaluated and compared after a period of time, for example, after 24 hours or 36 hours. Further, these characteristics may be evaluated relative to other compositions, such as commercially available compositions.

[0018] Depending on the intended application, for example a stick, the hardness of the composition may also be taken into account. The hardness of a composition may, for example, be expressed in gram-force (gf). The composition of the present invention may, for example, have a hardness ranging from 20 gf to 2,000 gf, such as from 20 gf to 900 gf, and further such as from 20 gf to 600 gf, including all intermediate ranges and sub-ranges.

[0019] This hardness can be measured in two ways, for example. A first hardness test is according to a method of penetrating a probe into the composition and in particular using a texture analyzer (for example, Texture Analyzer model PLUS-UPGRADE from Stable Micro Systems equipped with a stainless steel cylinder having a height of 28 mm and a diameter of 2 mm). The hardness measurement is carried out at 20 °C in the center of 5 samples of the composition. The cylinder is introduced into each sample of composition at a pre-speed of 2 mm / s then at a speed of 0.5 mm / s and finally at a post-speed of 10 mm / s, the total displacement being 2 mm. The recorded hardness value is that of the first maximum peak before the drop in the observed value.

[0020] The second hardness test is the "cheese wire" method, which consists of cutting a composition into a 12.4 mm diameter rod and measuring its hardness at 20°C using a DFGHS 2 tensile testing machine from Indelco-Chatillon Co. or a similar machine at a speed of 100 mm / minute. The hardness value obtained by this method is expressed in grams as the shear force required to cut a rod under the above-mentioned conditions. According to this method, the hardness of the compositions according to the present invention which may be in the form of rods may, for example, range from 120 gf to 270 gf, preferably from 170 gf to 220 gf, for a rod sample of 12.4 mm diameter.

[0021] The hardness of the composition of the present invention may be such that the compositions are self-supporting and may readily disintegrate to form a satisfactory deposit on keratinous materials. In addition, this hardness may impart good impact resistance to the inventive compositions, which may be molded or cast, for example in the form of sticks or cups.

[0022] A person skilled in the art may choose to evaluate a composition using at least one of the hardness tests described above depending on the intended application and the desired hardness. If an acceptable hardness value is obtained, taking into account the intended application, from at least one of these hardness tests, the composition falls within the preferred embodiments of the invention.

[0023] “Substituted” as used herein means comprising at least one substituent. Non-limiting examples of substituents 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, sulfonate groups, thiosulfate groups, siloxane groups, and polysiloxane groups. The substituent(s) may be further substituted.

[0024] “Volatile” as used herein means that the flash point is less than about 100°C.

[0025] “Non-volatile,” as used herein, means having a flash point greater than about 100°C.

[0026] “Low water content” means that the compositions contain less than 6% of water (by weight). Preferably, the compositions of the present invention contain less than 5% water, and preferably less than 4% water.

[0027] “Anhydrous” means that the compositions contain less than 1% water (in weight). Preferably, the anhydrous compositions of the present invention contain less than 0.5% water, and preferably no water.

[0028] “Polymer” as used herein means a compound that is made up of at least two monomers.

[0029] “Exempt” or “substantially exempt” or “devoid of” as used herein means that, although it is preferable that no amount of the specific component is 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 conditioning compositions of the invention. Thus, for example, "free of triethanolamine (TEA)" means that TEA is absent from the composition (i.e. i.e., 0% by weight), “substantially free of TEA” means that TEA is present in amounts not exceeding 1% by weight, and “TEA-free” means that TEA is present in amounts not exceeding 0.5% by weight, based on the total weight of the composition. The same nomenclature applies to all other ingredients identified in the application, such as, for example, silicone oils (“free of volatile silicone oils,” “substantially free of volatile silicone oils,” and “free of volatile silicone oils” have meanings consistent with the discussion in this paragraph), even if not specifically discussed for each identified ingredient. The discussed examples of the use of this language are intended to be exemplary and not limiting.

[0030] The compositions and methods of the present invention may "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. For the purposes of the compositions and methods of the present invention where the invention "consists essentially of" the identified ingredients and / or process steps, the "fundamental and novel property" of such compositions and / or methods is "to have no animal-derived ingredients and / or beeswax."

For purposes of the present application, it is to be understood that this definition of the term "oil" is broader than typical definitions of the term "oil" and includes substances that are solid at room temperature and atmospheric pressure but have melting points, as defined herein, below 40°C. This is done in part to allow for the calculation of the weights and ratios disclosed herein and / or to allow for the inclusion of higher viscosity materials within the definition of "oil".

[0033] Natural oil(s) are oils recovered or extracted from foods, and / or preferably oils recovered from plants or other plant life (as opposed to oils that are derived from natural sources by reactions and are not "natural oil(s)" as used herein). For example, vegetable oils include glyceride triesters, which are generally triesters of fatty acids and glycerol, the fatty acids of which may have varying chain lengths from C4 to C24, where these chains may be saturated or unsaturated and straight or branched.

[0099] Example 1 Sample Composition (Colored Lipstick)

[0100] [Tables3] INGREDIENT Amount (% by weight of the total weight of the COMPOSITION) Natural Filler Particles (Cellulose or Mica) 0.5% to 5% Behenyl Alcohol 3% to 6% Additional Waxes (Candelilla and Sunflower Seed) 10% to 15% Liquid Fatty Alcohol Oil / Ester Oil 20% to 40% Natural Oils 30% to 45% Pigments 8% to 15% Others (e.g., emollients, antioxidants, fragrance) 0% to 2%

[0101] Example 2 Preparation of a sample lipstick composition

[0102] Grind the pigments in the oil phase, until the desired dispersion is obtained.

[0103] Heat the pigment grinding to 90°C, mix with a propeller mixer.

[0104] Add the behenyl alcohol waxes, candelilla wax and sunflower wax until melted. Continue mixing for 15 minutes.

[0105] Add bis-diglyceryl polyacyladipate after melting (optional).

[0106] Add a natural filler (cellulose or mica) and mix until you obtain a homogeneous liquid.

[0107] Pour the liquid mass (at 90°C) into a lipstick mold at room temperature, cool the mold to -18°C to produce colored lipsticks. Example 3: Comparative test

[0108] Identical compositions were prepared according to the sample composition of Example 1 and the preparation method of Example 2, except for the amount of natural filler particles added as explained below.

[0109] A control composition containing no natural filler was prepared. Three compositions containing cellulose particles at levels of 1.5%, 3% and 5% were prepared (M1.5, M3 and M5). And three compositions containing mica particles at levels of 1.5%, 3% and 5% were also prepared (C1.5, C3 and C5).

[0110] The hardness of all the prepared compositions was tested using the two test procedures previously presented in the application. The results indicated that the control composition without filler and the compositions containing 5% mica or cellulose (M5 or C5) had approximately the same maximum positive force (about 280 g). In contrast, the compositions containing 1.5% or 3% natural fillers (C1.5, C3 and M3) surprisingly had a significantly higher maximum positive force (about 290 g or more), indicating that the compositions have better hardness properties. M1.5 (1.5% mica), however, exhibited lower hardness properties than the control composition.
