Description

Technical Field

[0001] The present application belongs to the technical field of cosmetics, and specifically relates to a lipstick and a preparation method thereof. Background Art

[0002] As a kind of lip beauty cosmetics, the main function of lipstick is to change the color of lips and make the overall makeup more vivid and energetic by emphasizing or changing the contour of lips.

[0003] Traditional lipstick formulas mainly include colorants, fillers, waxes, oils, pearlescent agents, flavors, and preservatives. During the preparation process, oils and waxes can be mixed well, but oils cannot be mixed with water, and waxes cannot be dissolved in water. If a large amount of water phase is added to the heated lipstick mixture, stratification and slag formation will occur, and a uniform lipstick cannot be prepared. Therefore, traditional lipstick formulas are usually anhydrous or contain a small amount of water phase, and therefore lack a moist feeling. Summary of the invention

[0004] To solve the above problems, the present application provides a lipstick and a method for preparing the lipstick. The lipstick has a high water content, so that it can have a good moist feeling.

[0005] The first aspect of the present application provides a lipstick, which comprises, by weight percentage:

[0006] Oil phase: 51% ~ 78%;

[0007] Aqueous phase: 20% to 40%;

[0008] Active matter: 0-5%;

[0009] Emulsified composition: 1% to 12%;

It is not intended to be limited to any theory or explanation. On the one hand, the emulsified composition has good compatibility with the waxes in the oil phase component, so that the wax substances still maintain their molding effect and a certain hardness under the condition of the dispersed phase. On the other hand, the emulsifier synergistic composition can further enhance the emulsification efficiency of the emulsified composition, make the micelle particle size formed in the emulsification process smaller and more uniform, and reduce the surface energy of the system at the same time, stabilizing the emulsion system. In this way, the risk of stratification, aggregation or demulsification of the emulsion system can be reduced. The lipstick formula provided by the present application can improve the upper limit of the content of the water phase in the emulsified system under the premise of ensuring product quality through the synergistic effect of the above-mentioned emulsified composition and the emulsified synergistic composition, thereby allowing the lipstick to have a higher water phase content. Therefore, in the lipstick formula provided by the present application, the water phase content can be increased to more than 20%, or even to 40%. Therefore, the lipstick of the present application can have both better texture and appearance, and has excellent moisturizing feeling and moisturizing degree.

[0033] In order to make the application purpose, technical solution and beneficial technical effect of the present application clearer, the present application is further described in detail in conjunction with the embodiments below. It should be understood that the embodiments described in this specification are only for explaining the present application, not for limiting the present application.

[0034] For simplicity, this application only explicitly discloses some numerical ranges. However, any lower limit can be combined with any upper limit to form an unclearly recorded range; and any lower limit can be combined with other lower limits to form an unclearly recorded range, and any upper limit can be combined with any other upper limit to form an unclearly recorded range. In addition, although not clearly recorded, each point or single value between the range endpoints is included in the range. Thus, each point or single value can be combined with any other point or single value as its own lower limit or upper limit or with other lower limits or upper limits to form an unclearly recorded range.

[0035] In the description of the present application, it should be noted that, unless otherwise specified, “above” and “below” are inclusive of the number, and the “multiple” in “one or more” means two or more than two.

[0036] The above application content of the present application is not intended to describe each disclosed embodiment or each implementation in the present application. The following description more specifically illustrates exemplary embodiments. In many places throughout the application, guidance is provided by a series of examples, which can be used in various combinations. In each example, enumeration is only used as a representative group and should not be interpreted as exhaustive.

[0037] As described in the background art, traditional lipsticks usually have waxes and oils as main ingredients, and have a relatively dry texture and lack a moist feeling.

[0038] In view of this, the inventor provides a lipstick and a method for preparing the lipstick after in-depth research and a large number of experiments.

[0039] The first aspect of the present application provides a lipstick, which comprises, by weight percentage:

[0040] Oil phase: 51% ~ 78%;

[0041] Aqueous phase: 20% to 40%;

[0042] Active matter: 0-5%;

[0043] Emulsified composition: 1% to 12%;

[0044] Emulsified synergistic composition: 1% to 5%.

[0045] The emulsifying composition includes lauryl PEG-9 polydimethylsiloxyethyl polydimethylsiloxane, caprylic / capric triglyceride, polyglyceryl-3 oleate and polyhydroxystearic acid. The emulsifying synergistic composition includes sumac wax and sorbitan olivate.

[0046] It is understandable that in the embodiments of the present application, the oil phase and the active substance may include various conventional oil phase components and active substance components applicable to lipstick. For example, the oil phase may include but is not limited to waxes, oils and other additives or adjuvants. The active substance may include substances with specific biological or chemical activity, for example, may include but is not limited to artificial / natural biological extracts, moisturizers or other active agents.

[0047] In response to the defect of lipstick lacking moist feeling, the inventor abandoned the traditional thinking that "too high water phase content in lipstick will inevitably cause instability of the formula system", and tried to increase the water phase by introducing an emulsification system into the lipstick formula to enhance the moist feeling of the lipstick. However, during the research and development process, it was found that with the increase in the amount of water phase added, the demulsification became more serious. During the preparation process of lipstick, wax stratification and uneven texture were prone to occur, resulting in defects such as the inability of lipstick to form a smooth stick shape, color bands and pits on the surface, and rough skin texture. In order to ensure product quality, under conventional emulsification systems, the upper limit of the amount of water phase added can only reach about 15%, which has a very limited effect on improving the moist feeling of lipstick.

[0048] After further research, the inventor provides the lipstick of the present application, the formula of which includes an emulsified composition composed of lauryl PEG-9 polydimethylsiloxyethyl polydimethylsiloxane, caprylic / capric triglyceride, polyglycerol-3 oleate and polyhydroxystearic acid, and an emulsified synergistic composition composed of lacquer fruit wax and sorbitan olive oil ester. It is not intended to be limited to any theory or explanation. On the one hand, the emulsified composition has good compatibility with the waxes in the oil phase component, so that the wax substances still maintain their molding effect and a certain hardness under the condition of the dispersed phase. On the other hand, the emulsifier synergistic composition can further enhance the emulsification efficiency of the emulsified composition, make the micelle particle size formed during the emulsification process smaller and more uniform, and at the same time reduce the surface energy of the system and stabilize the emulsion system. In this way, the risk of stratification, aggregation or demulsification of the emulsion system can be reduced. The lipstick formula provided by the present application can increase the upper limit of the content of the water phase in the emulsified system under the premise of ensuring product quality through the synergistic effect of the above-mentioned emulsified composition and the emulsified synergistic composition, thereby allowing the lipstick to have a higher water phase content. Therefore, in the lipstick formula provided by the present application, the water phase content can be increased to more than 20%, or even to 40%. Therefore, the lipstick of the present application can have both better texture and appearance, and has excellent moisturizing feeling and moisturizing degree.

[0049] In some embodiments, the lipstick may include, by weight percentage:

[0050] Oil phase: 51% ~ 61%;

[0051] Water phase: 30% to 40%;

[0052] Active matter: 1% to 5%;

[0053] Emulsified composition: 4.5% to 7.5%;

[0054] Emulsified synergistic composition: 1.5% to 2%.

[0055] In some embodiments, in the emulsified composition, the mass ratio of lauryl PEG-9 polydimethylsiloxyethyl dimethicone, caprylic / capric triglyceride, polyglyceryl-3 oleate and polyhydroxystearic acid can be 1:(0.25-10):(0.25-12):(0.1-3).

[0056] For example, the mass ratio of lauryl PEG-9 polydimethylsiloxyethyl dimethicone to caprylic / capric triglyceride can be 1:0.25, 1:0.5, 1:1, 1:2, 1:5, 1:8, 1:10, or within the range of any two of the above ratios.

[0057] For example, the mass ratio of lauryl PEG-9 polydimethylsiloxyethyl dimethicone to polyglyceryl-3 oleate can be 1:0.25, 1:0.5, 1:1, 1:2, 1:5, 1:8, 1:10, 1:12, or within the range of any two of the above ratios.

[0058] For example, the mass ratio of lauryl PEG-9 polydimethylsiloxyethyl polydimethicone to polyhydroxystearic acid can be 1:0.1, 1:0.3, 1:0.5, 1:1, 1:2, 1:3, or within the range of any two of the above ratios.

[0059] Without intending to be bound by any theory or explanation, when the mass ratio of each component in the emulsified composition is within the above-mentioned suitable range, it is conducive to forming a stable emulsified aqueous phase during the preparation of lipstick, reducing the risk of demulsification. As a result, the risk of stratification of the liquid in the emulsified system can be reduced, which is conducive to forming a smooth and flat solid after the liquid is cooled, thereby making the lipstick have a better texture and appearance.

[0060] In some embodiments, in the emulsified synergistic composition, the mass ratio of sumac wax to sorbitan olivate can be 1:(0.5-10), for example, 1:0.5, 1:1, 1:2, 1:3, 1:5, 1:8, 1:10, or within the range of any two of the above ratios.

[0061] Preferably, in some embodiments, in the emulsified synergistic composition, the mass ratio of sumac wax and sorbitan olivate can also be 1:(1.8-2.2), for example, it can be 1:0.5, 1:1, 1:2, 1:3, 1:5, 1:8, 1:10, or within the range of any two of the above ratios.

[0062] Without intending to be limited by any theory or explanation, when the mass ratio of each component in the emulsification enhancement composition is within the above-mentioned suitable range, the emulsification system can be allowed to have a higher water phase content under the premise of stabilizing the emulsified water phase, thereby allowing the finished lipstick to have a higher water content and a more uniform and delicate texture. This is conducive to further improving the moisture and skin feel of the lipstick.

[0063] In some embodiments, the oil phase may include hydrogenated polyisobutene, tocopherol (vitamin E), ethylhexylglycerin, dimethicone, dimethicone / vinyl dimethicone crosspolymer, kaolin, trimethylsiloxysilicate, synthetic wax, diethylhexyl carbonate, isododecane, glyceryl behenate / eicosanedioate, disteardimonium hectorite, propylene carbonate polyglyceryl-3 oleate, caprylic / capric triglyceride, polyhydroxystearic acid, lauryl PEG-9 polydimethylsiloxyethyl dimethicone, jojoba esters, polyglyceryl-2 triisostearate 、 Triethoxycaprylylsilane, vinyl dimethicone / methicone silsesquioxane crosspolymer, HDI / trimethylol hexyllactone crosspolymer, silica, lecithin, isopropyl myristate, ethylhexyl palmitate, isostearic acid and silica dimethyl silylate, CI 77891, CI 73360, CI 77499 or a combination of the following.

[0064] It is understandable that those skilled in the art can select appropriate oil phase components and their contents according to product requirements.

[0065] In some embodiments, the aqueous phase may include one or a combination of deionized water, hydroxyethyl urea, 1,2-hexanediol, 1,2-pentanediol, p-hydroxyacetophenone, and sodium chloride.

[0066] It is understandable that those skilled in the art can select appropriate oil phase components and their contents according to product requirements. Exemplarily, based on the total mass of the aqueous phase as 100%, the aqueous phase can include 45% to 70% water, 0 to 25% Aloe vera (ALOEBARBADENSIS) leaf juice, 3% to 15% glycerol, 2% to 4.2% 1,2-hexanediol, 2.8% to 7% hydroxyethyl urea, 2.8% to 8.4% butanediol, 0 to 1.5% 1,2-pentanediol, 0 to 2.8% p-hydroxyacetophenone and 0 to 3% sodium chloride, or a combination of several thereof.

[0067] In some embodiments, the active ingredient may include one or a combination of MYROTHAMNUS FLABELLIFOLIA leaf / stem extract, acetylated sodium hyaluronate, sodium hyaluronate, sodium hyaluronate crosspolymer, hydrolyzed sodium hyaluronate, PAEONIA SUFFRUTICOSA seed oil, PAEONIA SUFFRUTICOSA root extract, squalane, aloe barbadensis leaf juice and collagen.

[0068] It is understandable that those skilled in the art can select appropriate active ingredient components and their contents according to product requirements.

[0069] A second aspect of the present application provides a method for preparing the lipstick of the first aspect, comprising the following steps S110 to S140.

[0070] S110, preparing phase A, comprising uniformly mixing the oil phase, the emulsified composition, and the emulsified synergistic composition at an emulsification temperature to obtain phase A.

[0071] In step S110, the oil phase, the emulsified composition, and the emulsified synergistic composition may include the oil phase, the emulsified composition, and the emulsified synergistic composition of any embodiment of the first aspect of the present application. The emulsification temperature has a meaning well known in the art, which can represent the temperature at which the emulsification reaction occurs in the emulsification system. Those skilled in the art can select a suitable emulsification temperature according to the composition of the emulsification system, which is not limited here.

[0072] S120, preparing phase B, comprising heating the water phase to an emulsification temperature to obtain phase B.

[0073] S130, preparing a mixed solution, including adding phase B to phase A, stirring at 3000 rpm to 7500 rpm for 5 min to 20 min, and cooling to 40° C. to 60° C. to obtain a mixed solution.

[0074] S140, preparing lipstick, including mixing the active substance and the mixed liquid evenly, and obtaining the lipstick after cooling.

[0075] According to the method of the present application, by selecting a suitable emulsifying composition and an emulsifying synergistic composition, a lipstick with a high water phase content can be prepared. Specifically, on the one hand, the emulsifying composition has good compatibility with the waxes in the oil phase component, so that the wax material can be present in the dispersed phase and still maintain its molding effect and a certain hardness. On the other hand, the emulsifying agent synergistic composition can further enhance the emulsification efficiency of the emulsifying composition, make the micelle particle size formed during the emulsification process smaller and more uniform, and at the same time reduce the surface energy of the system and stabilize the emulsion system. In this way, the risk of stratification, aggregation or demulsification of the emulsion system can be reduced. Thus, through the synergistic effect of the above-mentioned emulsifying composition and the emulsifying synergistic composition, the upper limit of the content of the water phase in the emulsifying system can be increased while ensuring the quality of the product, so that the prepared lipstick has a higher water phase content. Thus, the lipstick prepared according to the method of the present application can have both better texture and appearance, and has excellent moisturizing and moisturizing.

[0076] In some embodiments, the emulsification temperature may be 75°C to 85°C, for example, 75°C, 78°C, 80°C, 82°C, 85°C, or within a range formed by any two of the above values.

[0077] When the emulsification temperature is within the above appropriate range, it helps the emulsifier to fully exert its effect, forming a uniform and stable emulsion system, further reducing the risk of stratification, aggregation or demulsification. In addition, by controlling the emulsification temperature, the emulsification process can be optimized and production efficiency can be improved.

[0084] (3) Slowly add phase B into phase A and stir at 3000 rpm to 7500 rpm for 5 min to 20 min. Stop stirring when the mixed solution is uniform and cool to 60° C. to obtain a mixed solution.

[0096] Test Section

[0097] (1) Moisturizing and transepidermal water loss test

[0098] Ten subjects with similar skin quality and age range were selected to reduce the impact of individual differences on the test results. Three different points were selected on the lips of each volunteer for testing. Using the stratum corneum moisture content test probe Corneometer CM825 (Courage-Khazaka, Germany) CU, the initial value of skin moisture was measured and recorded at each selected point. After measuring the initial moisture content, the subjects were asked to evenly apply a layer of lipstick sample on their lips. The amount and uniformity of application were controlled to ensure the consistency of the test. At different time points after applying lipstick (immediately, 4h and 8h), the moisture content test probe was used again to measure and record the skin moisture content at each point, and the average value was taken as the skin moisture content at the corresponding time point. Based on the measured data, the skin moisture change rate at each point at different time points was calculated. The moisture change rate can be calculated by the following formula: Moisture change rate = (moisture content after using lipstick-initial moisture content) / initial moisture content × 100%.

[0099] The average value of the moisture change rate of the lip skin of each subject at each time point was calculated as the moisture change rate of the lipstick at each time point. Among them, the immediate moisture change rate was recorded as Q1, the 4h moisture change rate was recorded as Q2, and the 8h moisture change rate was recorded as Q3.

[0100] (2) Yield test

[0101] According to the formula and steps of each embodiment and comparative example, 20 lipsticks were prepared for each embodiment and comparative example. After the preparation, the lipstick was observed in appearance. If it was a smooth and flat solid, it was a qualified product, otherwise it was a defective product. Yield = number of qualified products / 100×100%.

[0102] (3) Skin sensory evaluation

[0103] The lipsticks prepared in the examples and comparative examples that were tested as qualified products in the appearance yield observation were subjected to skin sensory evaluation by the subjects. The recorded results were based on the evaluation results of more than 80% of the subjects.

[0104] The test results of various embodiments and comparative examples are shown in Table 3.

[0105] Table 2

[0106]

[0107]

[0108] Table 3

[0109]

[0110]

[0111] From Table 2 and Table 3, it can be found that the lipstick of the present application has an excellent water-gloss effect, which can effectively increase the moisture of the lip skin and make the lips fuller. Not only that, the lipstick of the present application also has excellent lip moisturizing performance, which can effectively retain moisture and maintain the moist state of the lip skin for a long time. The lipstick of the present application can effectively reduce the risk of stratification, aggregation or demulsification of the emulsion system by adding an emulsifying composition and an emulsifying synergistic composition. When the water phase content in the lipstick formula reaches 20% to 40%, the lipstick of the present application can still have a good texture and appearance. Therefore, the yield of the lipsticks of Examples 1 to 18 can reach more than 90%, and the uniformity, fineness and moisture of the texture in the skin sensory evaluation can meet the needs of users. In particular, in the lipstick formulas of Examples 1 to 10 and 13 to 16, the ratio of each material in the emulsifying composition and the emulsifying synergistic composition is within a suitable range, which can better stabilize the emulsifying system. Therefore, the yield of the lipsticks of Examples 1 to 10 and 13 to 16 can reach 100%. At the same time, the prepared lipsticks not only have excellent moisture, but also have the best uniform and fine texture.

[0112] In contrast, the lipstick formulas of Comparative Examples 1 to 2 are difficult to form a stable emulsified system without the addition of an emulsifying composition. Therefore, the lipsticks of Comparative Examples 1 to 2 all have relatively serious demulsification during the preparation process, and it is impossible to obtain a uniformly mixed lipstick material body, so the yield, transepidermal water loss test and skin sense evaluation were not carried out. Although the lipstick formulas of Comparative Examples 3 to 4 add an emulsifying composition, no emulsifying synergistic composition is added. Therefore, Comparative Examples 3 to 4 have limited stabilizing effects on the emulsified system, and some of the prepared lipsticks still have color bands, uneven surfaces, and water on the surface after long-term storage, resulting in a yield lower than that of Examples 1 to 18, and some negative comments also appeared in the skin sense evaluation.

[0113] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed in the present application, and these modifications or replacements should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
