Description

Technical Field

[0001] The invention relates to the technical field of cosmetic production, and in particular to a high-moisturizing repairing composition capable of producing pearlescent luster, and application thereof, and daily chemical products. Background Art

[0002] The history of lotion has a long history, and its roots can be traced back to the beauty secrets of ancient China, when people used natural ingredients such as watermelon juice and tea leaves to make juice for facial care to achieve the purpose of moisturizing and nourishing. In 1897, Shiseido, as a pioneer of Western pharmacies, launched its first cosmetics, which also marked the birth of the world's first toner - Red Honey Dew. This product was revolutionary at the time because it introduced hyaluronic acid as an ingredient for the first time, an innovation that is very forward-looking even today. In 1917, Shiseido once again led the trend and launched the world's first whitening lotion. The product was inspired by the widespread folk practice of bleaching skin with cucumber water, and Shiseido transformed its concept into an actual skin care product. In 1968, the Clinique brand launched an innovative cleansing water, which not only broke the traditional concept of lotion as just skin care, but also popularized the importance of removing the aging stratum corneum. In 1980, Japanese brand SK2 incorporated natural yeast ingredients found in the winemaking process into skin care essence water, thus taking a leading position in the skin care field of fermented essence water. This innovation not only consolidated SK2's position in the skin care industry, but also marked the continuous evolution and diversification of the lotion product category.

[0003] Toner is a common dosage form for daily skin care and an important step in the skin care routine. It plays a connecting role in basic facial care. The main functions of toner include softening cuticles, replenishing nutrients, and calming and soothing the skin. The appearance of toner is relatively simple, and the most common one is transparent. This type of toner is transparent from appearance to texture. This type of toner is usually refreshing, but the moisturizing effect may not be very good. There are also emulsion types. The texture of this type of toner is between transparent and emulsion, and some may be translucent. Compared with the transparent type, the emulsion type has a higher oil content, so the moisturizing effect is better, but the texture may be stickier.

[0004] From L'Oreal's "Genius Water" to Lancome's "Aurora Water", lotions have always been popular with consumers for their unique appearance and effects. Competition in the market for this type of product has become increasingly fierce. In order to attract consumers' attention, various dosage forms have appeared on the market, such as double-layer, triple-layer, gold foil water, bubble water, solid water, etc. However, there are relatively few products in the form of pearlescent water.

[0005] Pearlescent effect means that the surface of cosmetics presents a pearl-like luster. This effect is achieved by adding specific pearlescent agents, which can be natural, such as shell powder and mica powder, or synthetic, such as higher fatty acids, alcohols, esters and stearates. Pearlescent effect can significantly enhance the attractiveness and beauty of products, making them more competitive in the market.

[0006] However, achieving a pearlescent effect in lotions is still challenging. Existing pearlescent agents, such as mica powder, may produce a large amount of residue after use, which may cause clogged pores, acne and blackheads. In addition, synthetic pearlescent agents are usually used in product systems with higher viscosity, such as shampoo, shower gel and facial cleanser, because these product systems are thicker, which is conducive to the formation and stability of pearlescence. In contrast, aqueous cosmetics have a lower viscosity, and it is difficult to form a stable pearlescent effect when using synthetic pearlescent agents, so they are not suitable for use.

[0007] Toners also need to be able to quickly replenish moisture to the skin and provide a unique refreshing and moisturizing feeling. In order to enhance the moisturizing effect, some products on the market add a large amount of moisturizers, such as hyaluronic acid and polysaccharide moisturizers. However, the amount of these ingredients added needs to be controlled. Too much will make the product feel sticky, and too little will not have a significant moisturizing effect, which is no different from ordinary pure water. Therefore, it is difficult for existing lotion technology to achieve both moisturizing and refreshing effects at the same time.

[0008] Chinese patent application 201710706541.X discloses a water-based cosmetic that can produce pearlescent long-lasting moisturizing, comprising the following components: 1.0-8.0% soybean phospholipid liposomes, 1.0-8.0% baobab seed extract and water. The application uses soybean phospholipid liposomes as a new type of pearlescent agent in water-based cosmetics to prepare a water-based cosmetic that can produce pearlescent and has a special appearance. The combination of soybean phospholipid liposomes and baobab seed extract has the effect of synergistically enhancing long-lasting moisturizing, and the moisturizing effect lasts for a long time. Soybean phospholipid liposomes themselves have a certain moisturizing function, and baobab seed extract is rich in plant small molecule RNA, which can help maintain the balanced expression of hyaluronic acid synthase HAS2, effectively promote hyaluronic acid synthesis, and have long-lasting moisturizing properties.

[0009] Chinese patent application 202311621565.7 discloses a liquid crystal cream with high-efficiency penetration ability, a preparation method and an application, wherein the liquid crystal cream comprises: a lipophilic emulsifier, a hydrophilic emulsifier, a long-chain fatty alcohol and ester, and the rest are a moisturizer, a thickener, a chelating agent, an emollient, a preservative, an active substance and deionized water;

[0010] The small liquid crystal moisturizing cream disclosed in the scheme has excellent skin feel, good absorbency, breathability and non-acne-causing properties. It can form a biomimetic moisturizing film with good skin affinity on the skin, which can enhance the hydration and moisturizing ability of the skin, effectively improve the skin condition, and achieve the effect of protecting and repairing the skin barrier. The system has good long-term stability and a complete liquid crystal structure. In addition, the scheme has shown through testing that the small liquid crystal cream has a significant penetration effect on both oil-soluble and water-soluble active substances.

[0011] Further observation of the scheme shows that the liquid crystal cream of the scheme mainly includes: lipophilic emulsifier, hydrophilic emulsifier and long carbon chain fatty alcohol and ester; and also includes one or more of moisturizer, thickener, emollient, preservative, active substance, oil, chelating agent and deionized water;

[0012] The hydrophilic emulsifier is composed of lecithin emulsifier, anionic emulsifier and polyglycerol emulsifier in a mass ratio of 1-20:8-40:2-60;

[0013] More specifically, the long-chain fatty alcohol and ester thereof are selected from one or more of cetyl alcohol, stearyl alcohol, arachidyl alcohol, behenyl alcohol, batyl alcohol, cetearyl alcohol, myristyl myristate and / or pentaerythritol distearate;

[0014] Anionic emulsifiers are selected from glyceryl stearate citrate, potassium cetyl phosphate, sodium stearoyl glutamate, sodium methyl stearoyl taurate, sodium di(lauryl glutamine) lysine and / or C 20-22 One or more of alcohol phosphates;

[0015] The polyglycerol emulsifier includes one or more of polyglyceryl-2 stearate, polyglyceryl-10 stearate, polyglyceryl-10 myristate, polyglyceryl-3 methyl glucose distearate, polyglyceryl-4 laurate, polyglyceryl-6 distearate, polyglyceryl-6 octastearate and / or polyglyceryl-10 dioleate;

[0016] However, the squalane glycol, sodium stearoyl glutamate and polyglyceryl-4 laurate in this solution are all used as emulsifiers in this solution, and their purpose is to form liquid crystals rather than to produce pearlescent effects;

[0017] Moreover, this solution consists of water phase and oil phase and is not a traditional "aqueous formulation product".

[0018] It can be seen that the technical problem actually to be solved by the present application is: how to provide a new moisturizing composition that can produce a pearlescent effect. Summary of the invention

[0019] The purpose of the present application is to provide a moisturizing and repairing composition capable of producing pearlescent effect, and the composition can produce pearlescent effect and has the characteristics of moisturizing at the same time.

[0020] To achieve the above-mentioned purpose, the present application discloses a highly moisturizing repair composition capable of producing pearlescent luster, comprising a component capable of forming pearlescent luster and a moisturizing component, wherein the component capable of forming pearlescent luster is a mixture of polyglycerol-2 laurate, sodium stearoyl glutamate, and batyl alcohol;

[0021] The moisturizing ingredient is a mixture of trimethylpentanediol / adipic acid / glycerin cross-linked polymer, glyceryl polyether-26, and hydrolyzed sodium hyaluronate;

[0022] The highly moisturizing repair composition capable of producing pearlescent light comprises the following components by mass fraction:

[0023]

[0024] The principle of the pearlescent effect of polyglyceryl-2 laurate, sodium stearoyl glutamate and batyl alcohol is mainly related to optical interference. Specifically, it is related to the following two factors:

[0025] 1. Layered structure: Polyglyceryl-2 laurate and sodium stearoyl glutamate surfactants can form a layered structure in water. This structure is due to the fact that these surfactants have both hydrophilic and hydrophobic parts in their molecular structure. In water, these molecules will self-assemble into a layered structure with the hydrophobic part inside and the hydrophilic part facing outward. Batyl alcohol also plays a key role here, increasing the stability of the product and improving the appearance, making the pearlescent appearance more obvious.

[0026] 2. Optical interference: When light passes through these layered structures, reflection and refraction occur. These layered structures are similar to thin films that can reflect and refract light. When light bounces between these layers, specific wavelengths of light will interfere constructively, resulting in specific colors.

[0027] In addition, Trimethylpentanediol / Adipic Acid / Glycerin Crosspolymer can increase the texture of cosmetics, making them easier to use and spread, and making the skin softer and smoother. In addition, this polymer also has the effect of long-lasting moisturizing, protecting the skin and preventing moisture loss;

[0028] Preferably, the following components are included by mass fraction:

[0029]

[0030] Preferably, the hydrolyzed sodium hyaluronate is a low molecular weight hydrolyzed sodium hyaluronate, and the low molecular weight hydrolyzed sodium hyaluronate is a hydrolyzed sodium hyaluronate with a total molecular weight and an average molecular weight of 3±0.5 kDa.

[0031] HA0.3 shows a good moisturizing effect in this application, but generally speaking, HA0.3 has a certain astringent feeling during use. However, this application can offset the astringent feeling of HA0.3 during use through the synergistic effect of shark liver alcohol, trimethylpentanediol / adipic acid / glycerol crosslinked polymer, and glyceryl polyether-26, while enhancing the skin affinity of the composition, making the skin feel refreshing and non-sticky.

[0032] In addition, the present application also discloses the use of the highly moisturizing repairing composition capable of producing pearlescent luster as described above for preparing cosmetics.

[0033] In addition, the present application also discloses a cosmetic containing 50-100 wt % of the highly moisturizing repairing composition capable of producing pearlescent luster as described above.

[0034] Preferably, the cosmetic is a liquid, and the liquid is specifically a toner, lotion, essence or spray.

[0035] The beneficial effects of this application are:

[0036] The polyglyceryl-2 laurate and sodium stearoyl glutamate surfactants in the highly moisturizing repair composition that can produce pearlescent light provided by the present application can form a layered structure in water. This structure is due to the fact that the molecular structure of these surfactants has both hydrophilic and hydrophobic parts. In water, these molecules will self-assemble into a layered structure with the hydrophobic part inside and the hydrophilic part facing outward. Squalane also plays a key role here, increasing the stability of the product and improving the appearance, making the pearlescent appearance more obvious. When light passes through these layered structures, reflection and refraction will occur. These layered structures are similar to thin films that can reflect and refract light. When light reflects between these layers, light of a specific wavelength will be constructively interfered, thereby producing a specific color.

[0037] In general, this pearlescent effect is produced by the special layered structure formed by surfactants in water and the interference of light in these layered structures. In addition, the mixing ratio of polyglyceryl-2 laurate, sodium stearoyl glutamate and batyl alcohol, the selection of different surfactants and the selection of different fatty alcohols will affect the formation and effect of pearlescent.

[0038] Trimethylpentanediol / Adipic Acid / Glycerin Crosspolymer can increase the texture of cosmetics, making them easier to use and spread, and making the skin softer and smoother. In addition, this polymer also has the effect of long-lasting moisturizing, protecting the skin and preventing water loss;

[0039] More importantly, generally speaking, HA0.3 has a certain astringent feeling during use. However, the present application can offset the astringent feeling of HA0.3 during use through the synergistic effect of shark liver alcohol, trimethylpentanediol / adipic acid / glycerol crosslinked polymer, and glyceryl polyether-26, while enhancing the skin affinity of the composition, making the skin feel refreshing and non-sticky.

[0060] For the specific addition amounts of the above components, see the detailed descriptions of the embodiments and comparative examples.

[0062] A highly moisturizing repairing composition capable of producing pearlescent luster, the formula of which is shown in Table 1:

[0063] Table 1

[0064]

[0065] Example 7

[0066] It is basically the same as Example 1, except that the same mass of hydrolyzed sodium hyaluronate (hydrolyzed sodium hyaluronate with low molecular weight (molecular weight span is 1000Da to 10000Da) and average molecular weight is 3±0.5kDa) is used to replace the low molecular weight hydrolyzed sodium hyaluronate in Example 1.

[0076] Table 3

[0077]

[0078] Performance Test:

[0079] Appearance and efficacy test:

[0080] 1. Pearlescent appearance comparison chart

[0081] refer to Figure 1-9 ,visible, Figure 1-3 The compositions obtained in the corresponding embodiments 1, 2 and 7 all have good pearlescent effects. Figure 4-9 It can be seen that when any one of polyglyceryl-2 laurate, sodium stearoyl glutamate, and batyl alcohol is missing or replaced, the compositions prepared in Comparative Examples 1-3 and Comparative Examples 8-10 cannot produce a good pearlescent phenomenon. The reason is that when any one of the above three substances is missing or replaced, the layered structure in the composition is reduced or cannot be formed, or a layered structure is generated but the stability of the layered structure is poor and disappears as the storage time increases.

[0082] 2. Skin moisture content test

[0083] 184 healthy male or female subjects aged 18 to 40 were selected and divided into 23 groups with 8 subjects in each group. The experiment was carried out in the same constant temperature and humidity environment (temperature 20℃~22℃, humidity 40%~60%). Before the experiment, the subjects were required to sit quietly in the environment for 20 minutes, and the test could be carried out only after the environment reached equilibrium.

[0084] The blank control was tested on both forearms of the first group. The blank control and the compositions prepared in the embodiments and comparative examples were randomly applied to the left and right forearms of the subjects in the remaining 22 groups. The concentration of (2.0±0.1) mg / cm 2 The tester will apply the dose to the test site before, 30 minutes and 4 hours after the test. The CM825 skin moisture tester tested the skin moisture content of the experimental site. Each subject was measured 3 times and the average value was taken. The test results are shown in Table 4:

[0085] Table 4

[0086]

[0087]

[0088] Result analysis:

[0089] 1. It can be seen from Examples 1-6 that when the amount of each component added is slightly changed without changing the type of each component, the stratum corneum water content and the stratum corneum water content change rate between Examples 1-6 fluctuate to a certain extent, but the overall fluctuation is small;

[0090] At the same time, it can be seen from the observation that Example 1 is superior to other examples under the test condition of the change rate of stratum corneum water content in 4 hours, which shows that Example 1 has a more long-lasting moisturizing ability;

[0091] 2. It can be seen from Examples 1 and 7 that when HA0.3 is replaced with low molecular weight hydrolyzed sodium hyaluronate, although the average molecular weights of the two are relatively close, the hydrating effect of low molecular weight sodium hyaluronate is obviously inferior to that of full molecular weight HA0.3. It can be seen that when full molecular weight HA0.3 is used in the formula, the composition exhibits a more significant hydrating ability;

[0092] Further observation of Example 1 and Example 8 shows that when HA0.3 is replaced with HA20 of full molecular weight but larger average molecular weight, the moisturizing ability of the composition shows a certain fluctuation. However, since HA20 has a higher average molecular weight, its skin feel will inevitably become more sticky.

[0093] 3. It can be seen from Example 1 and Comparative Examples 1-4 that when other similar components are used to replace the pearlescent components in the present application, the stratum corneum water content and the rate of change of stratum corneum water content in Comparative Examples 1-4 are reduced to varying degrees, but it is worth noting that the moisturizing components in Comparative Examples 1-4 are consistent with those in Example 1. Therefore, according to common sense, when only the pearlescent components are replaced, the moisturizing performance of Comparative Examples 1-4 should be close to that of Example 1, while the hydrating capacity of Comparative Examples 1-4 has a certain degree of downward trend. It can be seen that there may be a certain synergistic effect between the pearlescent components and the moisturizing components in the present application, thereby improving the hydrating capacity of the composition. After analysis, the principle may be that the pearlescent structure formed can increase the contact area between the product and the skin, so that the moisturizing components are more evenly distributed on the skin, thereby helping to better lock in moisture and improve the moisturizing effect. In addition, the components in the pearlescent structure also help to form a protective film on the skin surface, reduce water loss, and help maintain the moisture balance of the skin;

[0094] Further observation of Comparative Examples 5-7 shows that after the moisturizing ingredients are replaced, the stratum corneum water content and the stratum corneum water content change rate of Comparative Examples 5-7 further show a downward trend, which shows that any of the moisturizing ingredients in the present application are irreplaceable;

[0095] 4. It can be seen from Example 1 and Comparative Examples 8-10 that when any of the pearlescent components are missing from the composition, the stratum corneum water content and the rate of change of stratum corneum water content in Comparative Examples 8-10 are decreased to varying degrees. However, it is worth noting that the moisturizing components in Comparative Examples 1-4 are consistent with those in Example 1. Therefore, according to common sense, the lack of the pearlescent component alone should only affect the pearlescent effect of the composition. However, the moisturizing ability of Comparative Examples 8-10 is reduced to a certain extent, which further proves that there is a synergistic effect between the pearlescent component and the moisturizing component.

[0096] Further observation of Comparative Examples 11-13 shows that when any of the moisturizing ingredients is missing, the water replenishment capacity of Comparative Examples 11-13 will be significantly reduced. On the one hand, compared with Comparative Examples 5-7, it can be found that after the components with other moisturizing effects are replaced in Comparative Examples 5-7, the difference in water replenishment capacity between Comparative Examples 5-7 and Comparative Examples 11-13 is not large;

[0097] On the other hand, the differences in the change rates of the stratum corneum water content of Comparative Examples 11-13 relative to Example 1 at 30 minutes were 24.43%, 24.58%, and 23.94%, respectively. It can be seen that the three ingredients with moisturizing effects, trimethylpentanediol / adipic acid / glycerol crosslinked polymer, glyceryl polyether-26, and low molecular weight hydrolyzed sodium hyaluronate, should all bring about a stratum corneum water content change rate of about 25%.

[0098] However, the sum of the three is only 75%, which is still far from the 94.01% of Example 1. Combined with the experience obtained from the summary of the above-mentioned Comparative Examples 5-7 (the synergistic effect between the pearlescent component and the moisturizing component can be formed), it can be known that only when the moisturizing component contains trimethylpentanediol / adipic acid / glycerol crosslinked polymer, glyceryl polyether-26, and low molecular weight hydrolyzed sodium hyaluronate at the same time, the synergistic effect between the pearlescent component and the moisturizing component can be fully exerted.

[0099] 3. Transepidermal water loss rate test

[0100] The transepidermal water loss value (TEWL value) is an important indicator for evaluating the strength of skin barrier function. The lower the value, the better the skin barrier and the better the skin's water retention ability. It is one of the important indicators for evaluating moisturizing efficacy.

[0101] The test method is the same as the test method for the moisture content of the upper stratum corneum. The instrument used is the VapoMeter skin transepidermal water loss measuring instrument to test the experimental site. The test results are shown in Table 5:

[0102] Table 5

[0103]

[0104]

[0105]

[0106] Result analysis:

[0107] 1. It can be seen from Examples 1-6 that when the amount of each component added is slightly changed without changing the type of each component, the transepidermal water loss value and the transepidermal water loss value change rate between Examples 1-6 fluctuate to a certain extent, but the overall fluctuation is small;

[0108] At the same time, it can be seen from the observation that Example 1 is superior to other examples under the test condition of the 4h transepidermal water loss value change rate. It can be seen that Example 1 has a longer-lasting moisturizing ability, and the skin barrier construction and repair ability of the composition is also an important reason for improving its long-lasting moisturizing ability;

[0109] 2. It can be seen from Examples 1 and 7 that when low molecular weight hydrolyzed sodium hyaluronate is used to replace HA0.3, although the average molecular weights of the two are relatively close, the skin barrier building and repairing ability of low molecular weight sodium hyaluronate is obviously inferior to that of full molecular weight HA0.3. It can be seen that when full molecular weight HA0.3 is used in the formula, the composition exhibits more significant skin barrier building and repairing ability;

[0110] Further observation of Example 1 and Example 8 shows that when HA0.3 is replaced with HA20 of full molecular weight but larger average molecular weight, the skin barrier construction and repair capabilities of the composition do not show significant fluctuations. At the same time, since HA20 has a higher average molecular weight, its skin feel will inevitably become more sticky.

[0111] 3. It can be seen from Example 1 and Comparative Examples 1-4 that when other similar components are used to replace the pearlescent component in the present application, the transepidermal water loss values ​​and the transepidermal water loss value change rates of Comparative Examples 1-4 are reduced to varying degrees, which shows that any of the pearlescent components in the composition cannot be replaced;

[0112] Further observation of Comparative Examples 5-7 shows that after the moisturizing ingredients are replaced, the transepidermal water loss values ​​and the transepidermal water loss value change rates of Comparative Examples 5-7 further show a downward trend, which shows that any of the moisturizing ingredients in the composition cannot be replaced;

[0113] 4. It can be seen from Example 1 and Comparative Examples 8-10 that when any of the pearlescent components is missing from the composition, the transepidermal water loss values ​​and the transepidermal water loss value change rates of Comparative Examples 8-10 decrease to varying degrees, which shows that any of the pearlescent components in the composition is indispensable;

[0114] Further observation of Comparative Examples 11-13 shows that when any one of the moisturizing ingredients is missing, the moisturizing ability of Comparative Examples 11-13 will be significantly reduced, which shows that any one of the moisturizing ingredients in the composition is indispensable.

[0115] Skin feel test

[0116] Test method: 35 testers were selected and divided into 7 groups on average. Skin feel tests were conducted on Example 1, Example 8, Comparative Examples 5-6, Comparative Examples 11-12, and Comparative Example 14. Before the test, the evaluator drew a circular area with a diameter of 2 cm inside the arm as the sample measurement area. Before testing the samples each time, the testers were required to wash with clean water and wipe the inside of the arm with a clean paper towel. The testers then took the same amount of sample and applied it to the corresponding parts, and recorded the skin feel at this time and scored it. The sensory evaluation test listed a total of 5 test words, and the specific contents were absorption speed before use, moisturizing, softness, freshness, etc. The specific evaluation criteria are shown in Table 6;

[0117] The average value is calculated based on the testers' scores, and the scoring results are shown in Table 7.

[0123] Note: Stickiness score = 10 points - freshness score. The higher the freshness, the lower the corresponding stickiness. At the same time, the higher the stickiness score, the stickier the product.

[0124] Results Analysis

[0125] As shown in Table 7, both Example 1 and Example 8 showed better moisturizing feeling during the actual use of the testers. At the same time, Example 1 had a better refreshing feeling than Example 8. At the same time, Example 1 had a lower stickiness feeling than Example 8.

[0126] Further observation of Example 1 and Comparative Examples 5-6 shows that when lubricant oil or glyceryl polyether-7 is used in the composition to replace trimethylpentanediol / adipic acid / glycerol crosslinked polymer or glyceryl polyether-26, the stickiness of Comparative Examples 5-6 shows a more obvious upward trend. It can be seen that when trimethylpentanediol / adipic acid / glycerol crosslinked polymer or glyceryl polyether-26 in the composition is replaced by other similar substances, the overall freshness of the composition has a significant downward trend, and the stickiness is improved accordingly.

[0127] Further observation of Comparative Examples 11-12 shows that when the composition lacks trimethylpentanediol / adipic acid / glycerol cross-linked polymer or glycerol polyether-26, the composition prepared in Comparative Examples 11-12 is lower in absorption speed, moisturizing degree, softness, freshness, etc. than Example 1, and observation of Comparative Examples 5-6 and Comparative Examples 11-12 shows that the stickiness of Comparative Examples 11-12 when lacking trimethylpentanediol / adipic acid / glycerol cross-linked polymer or glycerol polyether-26 is less different from that of Comparative Examples 5-6. It can be seen that the use of lubricant oil or glycerol polyether-7 for replacement may improve the skin feel to a certain extent, but the extent of improvement is very limited;

[0128] Further observation of Comparative Example 14 shows that Comparative Examples 11-12 respectively add trimethylpentanediol / adipic acid / glycerol crosslinked polymer and glycerol polyether-26 relative to Comparative Example 14, and the freshness of the two is improved by 1.6 and 1.7 respectively relative to Comparative Example 14, but Example 1 is improved by 5.4 relative to Comparative Example 14. It can be seen that in the actual experience process, the simple superposition of Example 1 relative to Comparative Examples 11-12 still has obvious improvement.
