Description

TECHNICAL FIELD

[0001] The present application relates to the field of cosmetics, in particular, to a natural foundation liquid with repair and anti-wrinkle effects and a preparation method thereof. BACKGROUND

[0002] With the increasing demand of consumers for the safety and efficacy of cosmetics, the "skin-nourishing" foundation liquid with the functions of concealing and skin care has become a market trend. In the prior art, the skin-nourishing function of the foundation liquid is mainly achieved by two ways: one is to directly add single skin care ingredients such as vitamins and hyaluronic acid in the traditional foundation formula; and the other is to replace synthetic esters with some natural oils.

[0003] However, the above technical solutions have inherent defects: first, the directly added active ingredients are independent of the color powder system, the active substances are easy to lose activity during storage, and it is difficult for them to effectively penetrate into the skin during makeup to play a role, so the skin care effect is limited. Secondly, most "natural" foundation liquids only focus on replacing the base oil phase, and the color powder is still treated on the surface with silicone oil or conventional oil, which only plays a role in dispersion and lubrication, and does not have skin care activity itself, and cannot contribute to skin care from the fundamental aspect of concealing. SUMMARY

[0004] The purpose of the embodiments of the present application is to provide a natural foundation liquid with repair and anti-wrinkle effects and a preparation method thereof.

[0005] In a first aspect, the present application provides a natural foundation liquid with repair and anti-wrinkle effects, which includes 8-15% modified color powder, 1-10% natural active substance system, and 20-30% silicone-free oil phase, based on the total mass of the natural foundation liquid; and the balance is an aqueous phase; wherein the natural active substance system includes 0.5-3.0% oil-soluble pine bark extract powder, 0.5-1.0% finger orange extract, and 0.5-1.5% rice PDRN. The modified color powder is obtained by coating the color powder with extract of Moringa oleifera.

[0006] The above technical solution is that the moringa seed extract is wrapped in the color powder, which makes the color powder change from an inert cover to an active ingredient carrier. When the foundation liquid is applied, the wrapped color powder can directly and densely contact the skin, and the active substances carried by the wrapped color powder can immediately play an antioxidant role, neutralize free radicals generated due to the presence of cosmetics, and strengthen the skin barrier from the source. At the same time, the modified color powder is compounded with the natural active substance system to produce a synergistic effect. In the natural active substance system, the oil-soluble pine bark extract acts as a barrier repair initiator and mainly acts on the epidermis to up-regulate the expression of AQP3, filaggrin and other genes, strengthen the "brick wall structure" of the skin, and improve the water retention and defense ability of the skin from the basic level. The finger orange extract acts as a collagen synthesis promoter and is rich in high-concentration vitamin C and polyphenols, which can penetrate into the dermis layer, stimulate the production of collagen, improve the elasticity and firmness of the skin, and directly resist the formation of wrinkles. The rice PDRN acts as a cell repair and connection enhancer, promotes the synthesis of key structural proteins at the dermal-epidermal junction, speeds up the self-repair process of the skin, and consolidates the barrier and collagen results built by the other two components. The three cover the complete skin health pathway of "epidermal barrier-dermal matrix-junction structure". Further, the system uses natural oils to build the oil phase, which has better compatibility with the lipid shell of the moringa seed wrapped color powder, and can maintain the stable dispersion of the color powder. At the same time, the oil phase system has good solubility for the oil-soluble pine bark extract, and can create a suitable polar environment for the whole system, promote the stable existence and subsequent transdermal release of the water-soluble active ingredients such as the finger orange extract and the rice PDRN in the emulsion system. Therefore, the silicone-free oil phase and other components in the system have a synergistic effect, which not only can be used as a basic matrix, but also can ensure that the synergistic effect of the functional color powder and the complex active substance system can be fully exerted.

[0007] In summary, the above technical solution successfully builds an internally linked and layer-by-layer synergistic technical system by organically combining the functional color powder, the synergistic active substance system and the adapted silicone-free base. Not only does it meet the market demand for all-natural ingredients, but also realizes a qualitative leap from "covering type" to "active care type" in the technical level of the foundation liquid product, bringing significant repair and anti-wrinkle effects.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0023] This application provides a natural foundation with repairing and anti-wrinkle effects. Based on the total mass of the natural foundation, the foundation comprises: 8-15% modified color powder, 1-10% natural active ingredient system, and 20-30% silicone-free oil phase; with the remainder being an aqueous phase. The natural active ingredient system includes: 0.5%-3.0% oil-soluble pine bark extract powder, 0.5%-1.0% finger lime extract, and 0.5%-1.5% rice PDRN. The modified color powder is obtained by encapsulating color powder with Moringa seed extract.

All the subjects have signed the informed consent form. Test the skin of the subjects as the test site for immediate test, compare the water content of the stratum corneum before using the product and after using the product for 28 days. Test the product according to the dosage of 2.0±0.1 mg / cm 2 , perform single coating, use latex gloves to evenly coat the sample in the test area (2cm 2 ×2cm 2 ), and use MPA4CM825 instrument to test. The skin transdermal water loss rate (%) data of the subjects after using the examples and the comparative examples are shown in Table 5. Skin repair efficacy index: skin transdermal water loss rate affects skin moisturizing and skin barrier efficacy; the higher the index is improved, the better the skin repair efficacy is.

[0075] The test results are shown in Table 5.

[0076] Table 5 Skin transdermal water loss rate (%)

[0077] From the data in the above table, it can be seen that: Under the test conditions, the transdermal water loss rate of the facial skin of each example after 28 days of using the test product was 7.14-7.39, which was significant; compared with 0 days, it can be seen that the transdermal water loss rate of the facial skin significantly decreased, thereby indicating that the test product has the effect of improving the skin barrier.

[0078] The data of each comparative example can be seen that the transdermal water loss rate of the facial skin after 28 days of using the test product was significantly higher than that of each example, and the effect was significantly lower than that of each example.

[0079] 2. Anti-wrinkle test: Select healthy female volunteers aged 25-45 without a history of allergies, set up self-control test, use non-invasive test method, Evaskin S5 takes pictures to analyze the number / volume / area of crow's feet wrinkles and under-eye wrinkles, and evaluate the anti-wrinkle effect of the product.

[0080] Use site: face, use method: take an appropriate amount of foundation liquid in the palm after cleansing in the morning and evening, evenly apply it to the whole face, gently pat until absorbed, then gently pull up and massage until completely absorbed. Use period: 28 days. Each test subject uses each example or comparative example test product for 28 days, and the instrument test results are shown in Table 6.

[0081] Table 6 Test results of test subjects using test products for 28 days

[0082] From the data in the above table, it can be seen that: After using the test product for 28 days, the number of crow's feet wrinkles decreased by 12.58%-13.24%, the volume of crow's feet wrinkles decreased by 15.87%-16.34%, the area of crow's feet wrinkles decreased by 14.87%-15.12%, the number of under-eye wrinkles decreased by 29.31%-31.45%, the volume of under-eye wrinkles decreased by 39.41%-41.15%, and the area of under-eye wrinkles decreased by 33.84%-35.01% compared with before use. Each of the above properties is higher than each comparative example; therefore, the scheme of the present application can effectively improve the number of crow's feet wrinkles and under-eye wrinkles, and has excellent anti-wrinkle effect.

[0083] 3. Concealing effect test Conducted on the skin of volunteers, covering artificial marks: pores and acne marks. Evaluated by artificial visual method.

[0084] On the inner forearm of a volunteer, clean and dry skin, draw two identical sized circular marks with a standard pigment pen. Take a photo of the uncoated area under standard lighting conditions. Take a fixed amount of sample of each example and comparative example, and evenly coat one of the marks. The other mark serves as a control. Immediately after coating, take a photo under the same lighting conditions. The covering effect is scored by at least 3 trained assessors according to the flaw covering degree scale. 0-10, 0= no covering at all, 10= complete covering.

[0085] The test results are as follows: Table 7

[0086] From the above results, it can be seen that: The foundation liquid of the embodiments of the present application does not contain silicone oil, and the concealing effect can reach the same as the system containing silicone oil, so it can be explained that the scheme of the present application can replace the silicone oil system formula. Further, since the scheme of the embodiments of the present application does not contain silicone oil, the modified color powder has better dispersibility, and compared with the ordinary untreated color powder (comparative example 6), it can provide a stronger concealing effect for the formula.

[0087] 4. Skin feel adjustment By at least 5 professional sensory assessors.

[0088] Steps and scoring scale: Instant coating stage: the assessor takes a standard amount, and experiences on the simulated skin with a standardized method. 15-30 minutes after coating, assess whether the skin is breathable, 0-10 points; if thick and film-like, score 1 point, if light and no feeling, score 10 points.

[0089] The test results are as follows: Table 8

[0090] From the above results, it can be seen that: Compared with comparative example 5, the scheme of the embodiments of the present application has a better skin feel adjustment function.

[0091] This is because the silicone oil system formula of comparative example 5 has a film forming feeling, and the skin breathability is not good, while the non-silicone oil system of the present application gives the skin better breathability.

[0092] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Those skilled in the art can make various modifications and changes to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
