Description

Technical Field

[0001] This invention relates to the field of daily cosmetics, and more specifically, to a mascara composition and its preparation method. Background Technology

[0002] Mascara is a common cosmetic product. Because Asian people's eyelashes are shorter, coarser, sparser, and grow at a downward angle, using mascara can make eyelashes appear thicker, longer, and curlier, while also making the eyes more expressive. It is an indispensable part of daily eye makeup.

[0003] Generally, mascaras can be divided into water-based (water-in-oil emulsion system) and oil-based (referring to anhydrous system or oil-in-water emulsion system). Among them, oil-based mascaras have better staying power and waterproof effect, but are more difficult to remove. Water-based mascaras are easier to wash off, but during the washing process, the pigment can easily transfer to the skin around the eyes, and the staying power is generally average, and they are prone to smudging around the eyes after sweating or producing oil. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a mascara composition capable of forming a continuous tubular film covering the eyelashes. This tubular film combines long-lasting wear with easy removal. During wear, the tubular film locks in the mascara ingredients and evenly coats the eyelash surface, resulting in naturally thick and long eyelashes with excellent staying power, preventing flaking or smudging. During removal, the tubular film can be easily wiped off with a makeup remover pad using warm water, and it peels off directly in blocks or strips without leaving any residue on the eyelids, thus solving the problem of pigment deposition around the eyes.

[0005] One aspect of the present invention provides a mascara composition, wherein, based on parts by weight, the mascara composition comprises the following components: 18-35 parts polymer latex; 0.5–3 parts of water-soluble film-forming polymer; 0.1–0.8 parts of aqueous thickener; The polymer latex comprises acrylate bimodal latex.

[0006] Furthermore, the acrylate bimodal latex is selected from aqueous dispersions of acrylate / ethylhexyl acrylate copolymers and acrylate / dimethylaminoethyl methacrylate copolymers as main components; these polymers simultaneously possess anionic and cationic groups, exhibiting dual electrical properties, thus resulting in stronger intermolecular forces during film formation and a denser film formation at high humidity. Further, the acrylate bimodal latex content is 25-30 parts. The acrylate bimodal latex is selected from one or more of Sima SYNTRAN 5778 and / or Wanhua Carfil 9123.

[0007] The acrylate bimodal latex has a pH of 7-9, a viscosity of 10-200 mPa•s, and a glass transition temperature of -10-0℃ at room temperature.

[0008] The water-soluble film-forming polymer comprises a polyvinylpyrrolidone polymer, and more specifically, the polyvinylpyrrolidone polymer is PVP K90 with a molecular weight of 900,000 to 1,500,000 Da. The content of the polyvinylpyrrolidone polymer is 0.5 to 1.5 parts.

[0009] When polyvinylpyrrolidone (PVP) K90 is compounded with acrylate / ethylhexyl acrylate copolymer and acrylate / dimethylaminoethyl methacrylate copolymer latex, it can enhance the strength of the tubular film, making eyelashes curlier for longer, while not being overly sticky, thus not affecting the smoothness and evenness of mascara application, and preventing excessive adhesion to eyelashes during removal. This improves the user experience during makeup removal and makes removal easier and more even.

[0010] Further, the aqueous thickener comprises hydroxyethyl cellulose, and the content of hydroxyethyl cellulose is 0.2 to 0.5 parts. Further, the polymer latex does not contain an oil-phase thickener.

[0011] When the aqueous thickener, such as hydroxyethyl cellulose, is compounded with acrylic (ester) copolymers / ethylhexyl acrylate and acrylic (ester) copolymers / dimethylaminoethyl methacrylate, it can improve the tubular encapsulation force of the mascara, making the film formed by the material continuous and tight, the tubular film is not easy to break, improves the ability to remove the mascara in one go, and makes the eyelashes achieve a thicker effect.

[0012] Furthermore, the content of the hydroxyethyl cellulose is 0.2 to 0.4 parts.

[0013] Furthermore, the present invention also provides an O / W mascara, the mascara comprising the following components: 25-30 parts of acrylate bimodal latex, 0.5-3 parts of water-soluble film-forming polymer, 0.1-0.8 parts of aqueous thickener, 0.5-2 parts of emulsifier, 15-20 parts of oil phase, 0.5-5 parts of volatile oil, 10-19.5 parts of non-volatile oil, 5-12 parts of colorant, 0.5-5 parts of moisturizer, 0.1-5 parts of filler, 0.1-0.8 parts of thickener, 0.01-0.1 parts of chelating agent, and the balance being water.

[0014] Furthermore, the acrylate bimodal latex comprises an aqueous dispersion latex with acrylate / ethylhexyl acrylate copolymer and acrylate / dimethylaminoethyl methacrylate copolymer as the main components; the water-soluble film-forming polymer comprises PVP K90; and the aqueous thickener comprises hydroxyethyl cellulose.

[0015] Further, the moisturizer may be selected from one or more of glycerin, propylene glycol, dipropylene glycol, butylene glycol, pentanediol, panthenol, sodium hyaluronate, and hyaluronic acid, preferably one or more of propylene glycol, dipropylene glycol, butylene glycol, and panthenol. Further, the moisturizer is propylene glycol, and the content of propylene glycol is 1 to 3 parts.

[0016] The chelating agent may be selected from one or more of disodium EDTA and tetrasodium EDTA.

[0017] The colorant may be selected from one or more of water-dispersible color pastes, color powders, and starch-like colorants, such as water-dispersible carbon black pastes.

[0018] Furthermore, the volatile oil is one or more of cyclopentamethoxysiloxane, low-viscosity polydimethylsiloxane, octyl polydimethylsiloxane, and isododecane, and the above volatile oil can provide the effect of quick makeup application for mascara.

[0019] The non-volatile oil is a mixture of fatty acids and waxes, wherein the fatty acids are C16-C22 fatty acids, such as stearic acid, and the content is 1.5 to 3 parts.

[0020] The wax is selected from one or more of the following: paraffin wax, microcrystalline wax, polyethylene wax, beeswax, candelilla wax, carnauba wax, and ceresin.

[0021] The wax is selected from a mixture of hard wax with a melting point of 80-90℃ and branched wax with a melting point of 65-75℃, with a content of 5-12 parts, so that the mascara can have both good support and combing properties.

[0022] Furthermore, the hard wax is one or more of microcrystalline wax and Brazilian palm (Copernicia cerifera) wax; the branched wax is beeswax.

[0023] The content of the microcrystalline wax is 0 to 1.5 parts, the content of the beeswax is 4 to 6 parts, and the content of the carnauba wax is 3 to 5 parts.

[0024] Furthermore, the non-volatile oil may further contain fatty alcohols, such as cetearyl alcohol, which provides the mascara with moisturizing and hydrating properties in parts by weight of 1.5 to 3 parts.

[0025] Furthermore, the emulsifier comprises a nonionic surfactant, preferably a nonionic surfactant with an HLB value greater than or equal to 10, such as PEG-100 stearate / glyceryl stearate. This component can disperse acrylate bimodal latex, allowing the fillers, moisturizers, water-soluble film-forming polymers, aqueous thickeners, and other effective ingredients to be evenly distributed in the mascara. This results in a mascara with better fluidity and spreadability, making it easier to apply and preventing clumping or uneven application. It also prevents deposition or stratification during storage, thus avoiding any impact on the use of the mascara.

[0026] The filler is a solid insoluble substance, such as powder or fiber. It can be selected from one or more of silica, silicone resin powder, PMMA, nylon fiber, and plant fiber, preferably one or more of silica or cellulose, wherein the silica content is 2 to 4 parts and the cellulose content is 1 to 5 parts.

[0027] Furthermore, the present invention discloses a mascara comprising the following components: Stearic acid 1-3 parts, cetearyl alcohol 2-4 parts, beeswax 4-6 parts, microcrystalline wax 0-1.5 parts, Brazilian palm (COPERNICIA CERIFERA) wax 3-6 parts, PEG-100 stearate / glyceryl stearate 1-2 parts, cyclopentasiloxane 1-6 parts, silica 2-4 parts, colorant 8-11 parts, propylene glycol 1-3 parts, hydroxyethyl cellulose 0.2-0.4 parts, polyvinylpyrrolidone 0.8-1.5 parts, triethanolamine 0.8-1.5 parts, acrylate / ethylhexyl acrylate copolymer and acrylate / dimethylaminoethyl methacrylate copolymer latex 25-30 parts.

[0028] The present invention also provides a method for preparing the mascara, wherein the method includes the following steps: i) Oil phase melting: Melt the non-volatile oils and emulsifiers evenly at 80℃~90℃ and set aside; ii) Aqueous phase pre-dispersion: Heat water to 70℃~80℃, and pre-disperse the aqueous phase thickener and water-soluble film-forming polymer evenly; add colorant, humectant, chelating agent, and water for homogeneous dispersion; iii) Add the volatile oils and fillers to the material obtained in step i), then homogenize and emulsify it with the material obtained in step ii), and cool it to 40-50°C; iv) After keeping the polymer latex in a water bath at 40-50°C, add it to the material obtained in step iii), cool it down and discharge the material to obtain the mascara product.

[0029] Furthermore, the method includes the following steps: 1) Melt the oil phase by heating stearic acid, cetearyl alcohol, beeswax and / or microcrystalline wax, coperniciacerifera wax, and PEG-100 stearate / glyceryl stearate at 80℃~90℃ until they are melted evenly and set aside. 2) Aqueous phase pre-dispersion: Heat water to 70℃~80℃, and pre-disperse hydroxyethyl cellulose and polyvinylpyrrolidone (PVP K-90) separately and evenly to ensure no fish-eye agglomeration; then add colorant, propylene glycol, triethanolamine, disodium EDTA, and water, and then put it into the main reaction vessel for stirring or homogenization; finally heat to 80℃~90℃ for later use. 3) Emulsification: Add cyclopentadimethylsiloxane and silica to the oil phase in step 1) and stir rapidly until homogeneous. Then immediately transfer to the main reaction vessel and homogenize and emulsify at high speed. Emulsify until a stable paste-like cream is formed, and then stir and cool to 45℃~50℃. 4) Preheating of film-forming agent: Take a suitable container and preheat the polymer latex raw material in a water bath at 45℃~50℃; 5) Film-forming agent mixing: Pour the preheated polymer latex into the main reaction vessel and stir evenly; 6) Discharge: Cool the material down to below 40℃ and then discharge it; 7) Filling: Fill the mascara container with the material at room temperature.

[0030] Beneficial effects 1) When the mascara disclosed in this invention is used, the various components work together to form a tubular film that continuously covers the eyelashes. This tubular film has the characteristics of good staying power and excellent user experience. During the makeup application process, the tubular film can lock in the ingredients in the mascara and evenly coat the surface of the eyelashes, making the eyelashes naturally thick and long, and less prone to flaking or smudging.

[0031] 2) During the removal process of the mascara disclosed in this invention, the tubular membrane structure can be easily wiped off with a makeup remover pad under the action of warm water. Moreover, during the removal process, the tubular membrane peels off in a relatively complete block or strip shape, achieving the technical effect of one-time removal without staining the eyelids. This can solve the technical problem of pigment deposition in the eye area caused by incomplete removal of makeup during makeup removal. Attached Figure Description

[0049] The formulations for Comparative Examples 1-9 are shown in Table 2.

[0050] Table 2 Comparative Mascara Formulations

[0051] II. Mascara Application Effect Test Test subjects: Eight consumers who use mascara regularly will be recruited for trial testing.

[0052] Test method: Subjects tried the mascara samples prepared by Examples 1-2 and Comparative Examples 1-9 in sequence. Each sample was brushed on the eyelashes 15 times in a "Z" pattern. The eyelashes were visually evaluated for "uniformity without clumping", "thickness", "curl", "easy removal", "long-lasting", "quick-drying" and "easy to apply" (the lowest score of 1 point is considered as not matching the performance, and the highest score of 5 points is considered as excellent performance).

[0053] The "makeup staying power" performance test was based on the makeup effect after 6 hours of wear. Detailed results are shown in Table 3 and... Figure 1 .

[0054] Table 3. Makeup effect and staying power ratings for examples and comparisons

[0055] As shown in Table 3, the mascaras prepared using Examples 1 and 2 are easy to apply, and after use, the eyelashes are uniform without clumping, with high density, high curl, good quick-drying effect, and good staying power.

[0056] Comparative Example 1 The resulting mascara composition did not contain hydroxyethyl cellulose, resulting in mediocre application performance, clumpy lashes, and only average volume and curl.

[0057] Comparative Example 2 The mascara produced did not contain PVP K90 polymer, so its uniformity and curl were average, and its staying power was also average.

[0058] Comparative Example 3 When the resulting mascara contains less polymer latex, the density and curl of the eyelashes are poor, and the quick-drying performance is reduced.

[0059] Comparative Example 4 If VP / hexadecene copolymer is added to the oil phase of the resulting mascara, there are no obvious disadvantages in its use.

[0060] Comparative Example 5 The resulting mascara contains xanthan gum in the aqueous thickener phase. This causes the thickener system to become too viscous, resulting in discontinuous mascara film formation and clumping of lashes, creating a "spider leg" effect.

[0061] Comparative Example 6 The resulting mascara contains a styrene / acrylate / ammonium methacrylate copolymer as a polymer latex, and its consistency during use is generally moderate.

[0062] Comparative Example 7 The resulting mascara contains polyurethane-35 as a polymer latex. However, the resulting film is too soft, dries slowly, clumps easily when applied, provides poor lash support, and produces a "spider leg" effect.

[0063] Comparative Example 8 If polyvinylpyrrolidone (PVP K-30) is added to the resulting mascara, the mascara will be too soft and sticky after forming a film, with poor uniformity and only average curl of the eyelashes.

[0064] Comparative Example 9 If polyvinylpyrrolidone (PVP K-120) is added to the resulting mascara, the mascara will be too hard and brittle after forming a film, resulting in a less dense makeup effect and generally less dense eyelashes.

[0065] Specific makeup removal method: Use a makeup remover pad to apply warm water for 30 seconds, then wipe.

[0066] At this point, the ease of makeup removal, whether it can remove solid makeup, whether it leaves residue on the eyelids after wiping with a makeup remover pad, and whether there is residue on the eyelashes after wiping with a makeup remover pad are all assessed to determine whether a tubular film has formed. The ease of removal is scored (the lowest score of 1 is considered a failure to meet the performance standard, and the highest score of 5 is considered excellent). The evaluation of makeup removal effectiveness is shown in Table 4 and... Figure 2 .

[0067] Table 4 Comparison of makeup removal effects in examples and comparative cases

[0068] As can be seen from the data in Table 4, the mascaras prepared in Examples 1 and 2 have excellent easy removal performance. They can be removed solidly after wet compress, and do not stain the eyelids after makeup removal. There is no residue on the eyelashes after removal.

[0069] Comparative Example 1 The prepared mascara lacks hydroxyethyl cellulose and cannot form a uniform tubular film, so it cannot be completely removed in a solid state during makeup removal, and its removal performance is also reduced.

[0070] Comparative Example 2 The prepared mascara lacks the added PVP K90 polymer. Although it can form a tubular film, the tubular film is easily broken and lacks strength, making it difficult to completely remove during makeup removal and failing to achieve the technical effect of one-time removal.

[0071] Comparative Example 3 When the prepared mascara contains less polymer latex, it cannot form a uniform tubular film on the eyelashes during use, making it difficult to remove the mascara, leaving more residue on the eyelashes, and easily causing pigment deposition around the eyes.

[0072] Comparative Example 4 If VP / hexadecene copolymer is added to the oil phase of the prepared mascara, it is difficult to remove during makeup removal, and there is residue on the eyelashes after wiping with a makeup remover cotton pad.

[0073] Comparative Example 5 If xanthan gum is added to the aqueous thickener in the prepared mascara, the overall viscosity of the thickener will be too strong, causing the tubular film to become discontinuous during mascara application. This will result in eyelashes sticking together easily, causing discomfort, and the mascara will also smudge and stick to the eyelids during makeup removal.

[0074] Comparative Example 6 The mascara was prepared using a styrene / acrylate / ammonium methacrylate copolymer latex. The resulting mascara film had excessive adhesion, making it difficult to remove, and it was prone to slight smudging of the eyelids during removal.

[0075] Comparative Example 7 The prepared mascara uses polyurethane-35 as the polymer latex, which is relatively easy to remove, but it tends to smudge around the eyes during removal and cannot be completely removed in one go.

[0076] Comparative Example 8 When polyvinylpyrrolidone (PVP K-30) is added to the prepared mascara, only part of the mascara tube film can be removed during removal, and it is easy to get on the eyelids, making it impossible to remove the mascara completely in one go.

[0077] Comparative Example 9 The resulting mascara contained polyvinylpyrrolidone (PVP K-120). It produced moderate lash density, offered low lash comfort, and required considerable force to remove completely, making it impossible to remove the mascara in one go.

[0078] In summary, the mascara compositions obtained by the technical solutions of Examples 1-2 of the present invention have excellent makeup effects, form a relatively complete tubular film, are easy to remove, leave no mascara residue after removal, and do not stain the eyelids. However, the technical solutions in the comparative examples cannot achieve the technical effects of the present invention.

[0079] The above embodiments are only used to illustrate the detailed method of the present invention. The present invention is not limited to the above detailed method, that is, it does not mean that the present invention must rely on the above detailed method to be implemented. Those skilled in the art should understand that any improvements to the present invention, equivalent substitutions of the raw materials of the product of the present invention, addition of auxiliary components, selection of specific methods, etc., all fall within the protection scope and disclosure scope of the present invention.
