Description

Technical Field

[0001] This invention relates to the field of cosmetics, and mainly discloses an anti-migration, waterproof and breathable composition and its uses in cosmetics. Background Technology

[0002] In today's society, with people's pursuit of beauty, cosmetics are increasingly valued in daily life. For example, makeup products can beautify one's image and enhance personal temperament; sunscreen products can protect the skin from excessive damage by ultraviolet rays; and whitening products can whiten the skin. As people's living standards improve and social activities increase, their performance requirements for cosmetics are becoming increasingly diversified and sophisticated. Cosmetics are required not only to have good effects but also to maintain the longevity and stability of makeup in various complex environments, while also ensuring the healthy breathing of the skin.

[0003] Currently, many cosmetics face numerous problems during actual use. For example, foundation and other makeup products are prone to migration, causing makeup to smudge and affecting not only appearance but also potentially causing embarrassment for consumers. Sunscreen products, due to migration, experience a decrease in sun protection effectiveness, and migration to areas such as around the eyes and lips can also cause irritation. In addition, liquids such as sweat can also affect the overall effect of cosmetics. In pursuit of waterproofing, some cosmetics add a large amount of waterproofing ingredients, such as waterproof resins. While this effectively reduces the impact of moisture on the cosmetics, it also hinders the exchange of gases between the skin and the outside world. Long-term use may lead to clogged pores, acne, and other problems, which are detrimental to skin health.

[0004] Therefore, the technical problem to be solved by the present invention is: how to obtain a composition that is anti-migration, waterproof and breathable, and add it to cosmetics to greatly improve the anti-migration performance and waterproofness of the product, while maintaining a certain degree of breathability and good skin feel. Summary of the Invention

[0005] The purpose of this invention is to provide an anti-migration, waterproof, and breathable composition comprising triacontyl PVP, surface-treated kaolin, and silica. This composition utilizes the synergistic effect between the three components triacontyl PVP, surface-treated kaolin, and silica to give cosmetics containing this composition excellent anti-migration properties, waterproofness, and breathability, as well as a good skin feel.

[0006] In addition, the present invention also provides the uses of the composition and its application in daily chemical products.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A migration-resistant, waterproof, and breathable composition comprising the following components: triacontyl PVP, surface-treated kaolin, and silica; wherein the mass ratio of triacontyl PVP, surface-treated kaolin, and silica is 0.025-3.5:0.05-10:0.025-5; and wherein the kaolin is silane-modified kaolin.

[0009] In the technical solution of this invention, surface-treated kaolin, silica, and triacontyl PVP (commonly used as a film-forming agent in cosmetics and possessing certain waterproof properties) are compounded in a certain proportion to form a combined raw material that simultaneously possesses anti-migration, waterproof, and breathable properties. This improves the practical application problems such as poor user experience and high cost associated with high-dose use of triacontyl PVP or other traditional film-forming agents, providing a good solution for the development of novel sunscreen cosmetics. Based on the results, it is speculated that its synergistic mechanism may be due to:

[0010] The long carbon chain (C30) of triacontyl PVP provides strong hydrophobicity, tending to escape the aqueous phase and adsorb at the interface or self-aggregate. Polyvinylpyrrolidone (PVP) is a water-soluble component that forms hydrogen bonds with water through polar amide groups, giving the molecule amphiphilicity. In solutions (such as water or organic solvents), the amphiphilicity of C30-PVP causes its molecules to spontaneously migrate to the interface. The hydrophobic C30 chain faces the nonpolar phase (such as air or oil), while the hydrophilic PVP portion faces the aqueous phase, forming a monolayer arrangement. As the solvent gradually evaporates, the solution concentration increases, and the intermolecular distance decreases. With further solvent evaporation, the synergistic effect of the PVP segments and C30 chains forms a three-dimensional network structure. Surface-treated kaolin partially possesses a cardboard structure in water; the addition of hydrophobic surface treatment to kaolin synergistically enhances water resistance. Silica forms bumps on the triacontyl PVP network structure, producing a lotus leaf-like effect, further enhancing water resistance. Its hydrophobic surface treatment combined with the long carbon chain of triacontyl increases skin affinity and enhances anti-migration properties. The combination of kaolin and silica particles in a network structure improves the partial directional arrangement of triacontyl PVP, thereby enhancing air permeability.

[0011] Preferably, the kaolin is one or more of the following: kaolin that has undergone surface modification treatment with triethoxyoctylsilane, polydimethylsiloxane, or hydrogenated polydimethylsiloxane.

[0012] Preferably, the average particle size of the silica is 2-12 μm.

[0013] Furthermore, the present invention discloses the use of the composition described above in the preparation of cosmetics.

[0014] Finally, the present invention discloses a cosmetic comprising the composition described above.

[0015] Preferably, the cosmetic contains 0.1 wt% to 18 wt% of the composition.

[0016] More preferably, the cosmetic also contains sunscreen, moisturizer, skin protectant, emulsifier, emulsion stabilizer and oil.

[0019] The physical sunscreen agent is one or both of titanium dioxide and zinc oxide;

[0020] The moisturizer is one or more of the following: glycerin, butylene glycol, propylene glycol, methyl glucoether-20, dipropylene glycol, and 1,2-pentanediol.

[0021] The skin protectant is one or more of the following: dipotassium glycyrrhizate, bisabolol, and ginger root extract;

[0022] The emulsifier is one or more combinations of sorbitan isostearate, lauryl PEG-9 polydimethylsiloxane ethyl polydimethylsiloxane, and PEG-10 polydimethylsiloxane.

[0023] The emulsifying stabilizer is one or more of the following: polyhydroxystearic acid, lithium distearate dimethylammonium montmorillonite, magnesium sulfate, sodium chloride, and isostearic acid.

[0024] The oil is one or more of the following: dibutyl adipate, diisopropyl sebacate, dioctyl carbonate, isononyl isononanoate, polydimethylsiloxane, and hydrogenated polyisobutylene.

[0025] More preferably, the dosage form of the cosmetic includes lotion, cream, essential oil, ointment, lotion, spray, gel, pressed powder or loose powder.

[0026] Compared with the prior art, the beneficial effects of the present invention are: compared with the use of traditional water-resistant film-forming agents that do not have anti-migration properties and high sealing properties, the present invention provides a composition that has strong anti-migration properties, high water resistance, and a certain degree of breathability. The composition utilizes the synergistic effect between three components: triacontyl PVP, surface-treated kaolin, and silica, so that cosmetics containing the composition have excellent anti-migration properties, water resistance, breathability, and skin feel.

[0119] Performance testing

[0120] Anti-migration test

[0121] Test according to the following scheme and corresponding test cases 1-11. The test results are shown in Table 7. Figures 1 to 33 As shown;

[0122] Qualified subjects were recruited and screened, and entered the laboratory according to the test schedule. After cleaning their faces with water, subjects sat quietly in a constant temperature and humidity room for 30 minutes. According to the test requirements, a 3×3cm area was selected on the subject's face, and a single application was made at a dosage of (2.0±0.1) mg / cm2. The test sample was evenly applied to the test area using a latex finger cot. T0 imaging: VISIA-CR imaging (light source: UV) was performed immediately after sample application. Tn imaging: VISIA-CR imaging (light source: UV) was performed at the required follow-up time.

[0123] Single-use sample: immediately after sample use (T0), after sample use (Tn = 2h, 4h).

[0124] The skin was analyzed using Image-Pro Plus comprehensive skin analysis software;

[0125] According to the statistical data on the proportion of sample area, the larger this value is, the larger the area covered by the sample, and the easier it is to spread.

[0126] Waterproof test

[0127] Test the following methods for test cases 1-11. The test results are shown in Table 9. Figures 34-55 As shown;

[0128] A certain amount (0.75mg / cm) 2 The sunscreen product was applied to a 50×50mm PMMA plate. The UV transmittance was quickly measured using a UV2000 UV transmittance analyzer to obtain the product's SPF (in vitro) value. The coated PMMA plate was then fixed to the bottom of a beaker containing water. The water in the beaker was stirred, and the plate was removed after 80 minutes. It was then allowed to air dry at room temperature, and the SPF (in vitro) value was retested.

[0129] The waterproof effect of the sample was calculated according to formula (1):

[0130]

[0131] In the formula: R W Indicates the water resistance rating; SPF A This indicates the SPF value of the sample after immersion in water; SPF B This indicates the SPF value of the sample before it was immersed in water.

[0132] Performance Evaluation

[0133] Evaluation method: Subjects self-assessed by applying an appropriate amount of sample evenly to the face and evaluating the following parameters.

[0134]

[0135] Subject information: 11 healthy male / female subjects, aged 20-40 years.

[0136] Test samples: Sunscreen samples from Application Examples 1-9.

[0137] Results statistics: The average score of each subject for each indicator is used as the final score for that indicator, and the comprehensive score is the average score of the four indicators.

[0138] Breathability test

[0139] The air permeability test was performed on the composition formulations corresponding to Case 12 and Application Example 13 using the following method, and the test results are shown in Table 7.

[0140] Select 300-mesh filter cloth, cut it to an appropriate size, unfold it and lay it flat on the board, and fix it with adhesive tape. Use a four-sided coating applicator with a thickness of 13µm to evenly coat the materials from Application Example 10 and Application Example 11 onto the filter cloth and let it dry.

[0141] Use a 100ml glass beaker, weigh about 50g of distilled water into the beaker, fix the dried filter paper on the top of the beaker, make two sets of samples in parallel, and use the uncoated filter paper as the blank sample.

[0142] After recording the total mass of each group of samples using an analytical balance, they were placed in a constant temperature incubator at 40℃ for 18 hours. After that, they were taken out and weighed again.

[0143] The air permeability of the sample relative to the blank group was calculated according to formula (2).

[0144]

[0145] In the formula: R r ΔM1 represents the relative air permeability; ΔM2 represents the change in water loss (g) of the sample before and after application; ΔM3 represents the change in water loss (g) of the blank sample before and after the test.

[0149]

[0150] Table 7. Data Table of Anti-migration Test Results

[0151]

[0152] Analysis of the data in Table 6 shows that the 2-hour migration and diffusion area ratio of the products in Examples 1-3 is 1%-4%, and the 4-hour migration and diffusion area ratio is 2%-4%, indicating that the compositions of Examples 1-3 of the present invention have excellent anti-migration ability and can significantly prevent product diffusion when added to the product.

[0153] Data from Application Examples 4-6 show that when any one of the components triacontyl PVP, kaolin, and silica is missing from the composition, the migration and diffusion area ratio of the product increases significantly. In particular, in Application Example 4, which lacks triacontyl PVP, the migration and diffusion area ratio reaches 6.14% at 2 hours and 7.33% at 4 hours.

[0154] Data from Application Examples 7-9 show that when the composition contains only one of the components triacontyl PVP, kaolin, and silica, the migration and diffusion area ratio of the product will increase significantly. In particular, Application Example 8, which contains only kaolin, shows a migration and diffusion area ratio as high as 8.48% after 2 hours and as high as 12.67% after 4 hours.

[0155] Further analysis of the data from examples 4-9 shows that when the three substances in the composition of the present invention are used together, they can synergistically enhance the anti-migration effect. Among the three components, triacontyl PVP, kaolin, and silica, triacontyl PVP has the best anti-migration effect. Theoretically, when the total amount is the same, the more of this component is used, the better the anti-migration effect. However, in the compositions of application examples 5-6, the amount of triacontyl PVP is significantly higher than that of application example 1, but its 2h and 4h migration diffusion area ratios are significantly higher than those of application example 1. Application example 1 has an extremely strong anti-migration effect, which shows that triacontyl PVP, kaolin, and silica have a significant synergistic effect in enhancing the anti-migration effect.

[0156] Application Example 10 uses trimethylsiloxysilicate instead of triacontyl PVP, kaolin and silica in its composition, but its anti-migration effect is far inferior to that of the triacontyl PVP, kaolin and silica composition of the present invention.

[0157] Application Example 11 is an example of the application of the composition of Example 1 of the present invention in sunscreen base makeup. It can be seen that the composition of the present invention also has a good anti-migration effect in different product formulations.

[0165] Analysis of the data in Tables 7 and 8 yields the following results:

[0166] Application Examples 1 to 3 all have extremely high waterproof rates, with Application Example 1 reaching as high as 221.8%; this indicates that the compositions of Examples 1 to 3 of the present invention have excellent waterproof capabilities. When added to a product, they can significantly improve the waterproof effect of the product, and they have an extremely high overall score of about 4.5.

[0167] Data analysis of application examples 1-6 shows that when the composition of application example 7 uses triacontyl PVP alone, it also has a good waterproof rate of 216.04%, but its skin feel score is low, with an overall score of only 2.23. When the compositions of application examples 8 and 9 use kaolin and silica alone, their waterproof performance data is low, especially in application example 8, which uses kaolin alone, with a waterproof rate of only 4.88%. The composition of application example 4, which combines kaolin and silica, only slightly improves the waterproof rate. The compositions of application examples 5 and 6, which combine triacontyl PVP with silica and kaolin respectively, may compromise the waterproof performance of triacontyl PVP, especially in application example 5, but they do improve the skin feel of the product to some extent. The compositions of application examples 1-3, which combine triacontyl PVP, silica, and kaolin simultaneously, maintain both a very high waterproof rate and a good skin feel, i.e., a good overall performance score.

[0168] The above data demonstrates that the composition of the present invention combines triacontyl PVP, silica, and kaolin simultaneously, utilizing the synergistic effect of the three components to achieve excellent waterproofing and significantly enhance the skin feel of the composition.

[0169] Application Example 10 uses the traditional film-forming substance trimethylsiloxysilicate instead of the composition of the present invention, and its waterproof rate is only 60.3%, which is far inferior to the waterproof effect of the composition of the present invention.

[0170] Application Example 11 is an example of the application of the composition of Example 1 of the present invention in sunscreen base makeup, with a water resistance rate of 233.11%, which shows that the composition of the present invention also has a good water resistance effect in different product formulations.

[0173] Table 9 shows the air permeability test data for Application Examples 12 and 13. Application Example 12 is the air permeability test formulation of the composition of Example 1. Application Example 12 is the air permeability test formulation using trimethylsiloxysilicate instead of the composition of Example 1. The data shows that compared with the formulation using the traditional film-forming substance trimethylsiloxysilicate, the formulation using the composition of Example 1 of the present invention has better air permeability, at 62.81%, which is 6.93% higher than that of Application Example 13.
