[0002] As consumers' demand for skin care quality increases, the market demand for high-efficiency moisturizing products is growing.

[0003] Most existing moisturizing products rely on traditional glycerin, propylene glycol and other hygroscopic agents to achieve moisturizing effects, but these substances can often only stay on the surface of the skin and cannot achieve long-term deep moisturizing.

[0004] In order to better improve the moisturizing effect, people usually choose to add plant extracts with moisturizing effects. By conditioning the skin with plant extracts, the skin's own water-locking ability is improved, thereby prolonging the moisturizing effect.

[0005] However, although existing moisturizing products with added plant extracts can prolong the moisturizing effect to a certain extent, the prolongation effect is not significant enough and still cannot meet the needs of consumers. Therefore, there is still room for improvement. Summary of the Invention

[0006] In order to better prolong the skin moisturizing effect, the present application provides a deep moisturizing composition containing baobab leaf extract, a preparation method and an application thereof.

[0007] In a first aspect, the present application provides a deep moisturizing composition containing baobab leaf extract, which adopts the following technical solution: The invention discloses a deep moisturizing composition containing an extract of baobab leaves.

[0012] By adopting the above technical solution and selecting water-soluble extracts, the active ingredients are more easily absorbed by the skin and the skin conditioning effect is better.

[0013] In a second aspect, the present application provides a method for preparing a deep moisturizing composition containing baobab leaf extract, using the following technical solution: A method for preparing the above-mentioned deep moisturizing composition containing baobab leaf extract comprises the following steps: Step 1) adding the baobab leaf extract, the Dendrobium officinale extract, the Selaginella thunbergii extract, and the lotus extract into water and mixing until dissolved to obtain a composite extract solution; Step 2) concentrating and drying the composite extract to obtain a deep moisturizing composition containing the baobab leaf extract.

[0014] By adopting the above technical solution, the baobab leaf extract, Dendrobium officinale extract, Selaginella extract, and lotus extract are first dissolved in water and then dried, so that the active ingredients of each extract are better mixed with each other, thereby exerting a better compounding effect, so that the deep moisturizing composition containing baobab leaf extract has better moisturizing effect and more lasting moisturizing effect.

[0015] Preferably, in the step 1), after mixing until dissolved, the mixture is kept at a constant temperature of 45-50° C. and stirred for 3-4 hours to obtain a composite extract.

[0016] By adopting the above technical solution, by specifically selecting a constant temperature of 45-50°C and stirring for 3-4 hours, the active ingredients can be mixed better and the moisturizing effect can be better prolonged.

[0017] Preferably, in step 2), when concentrating the composite extract, rotary evaporation is used, and the concentration temperature is 50-55°C.

[0018] By adopting the above technical solution and specifically selecting the concentration temperature, the damage of high temperature to the active ingredients is reduced, so that the deep moisturizing composition containing the baobab leaf extract has a better effect.

[0019] In a third aspect, the present application provides an application of a deep moisturizing composition containing an extract of baobab leaves, using the following technical solution: An application of the above-mentioned deep moisturizing composition containing baobab leaf extract, wherein the deep moisturizing composition containing baobab leaf extract is added to a skin care product to prepare a skin care product with moisturizing effect, and the mass content of the deep moisturizing composition containing baobab leaf extract in the skin care product is 0.5-10%.

[0020] By adopting the above technical solution, the prepared skin care product can comprehensively repair the skin, thereby having a good moisturizing effect, and the moisturizing effect is relatively long-lasting.

[0021] Preferably, the mass content of the deep moisturizing composition containing baobab leaf extract in the skin care product is 1-2%.

[0022] By adopting the above technical solution and specifically selecting the mass content of the deep moisturizing composition containing baobab leaf extract in the skin care product to be 1-2%, the skill can achieve a better moisturizing effect, while reducing the waste of raw materials, having higher economic value, and being more conducive to promotion.

[0090] Preparation of the test sample: 2 g of the deep moisturizing composition containing the baobab leaf extract and 98 g of deionized water were mixed evenly until completely dissolved to obtain the test sample.

[0091] Experiment 2 According to T / JSRH 003-2023 "Hyaluronidase inhibition method for testing the anti-allergic activity of cosmetic raw materials", the hyaluronidase inhibition rate (%) of the test samples prepared from the deep moisturizing composition containing the baobab leaf extract of each embodiment and comparative example was tested.

[0092] Preparation of the test sample: 2 g of the deep moisturizing composition containing the baobab leaf extract and 98 g of deionized water were mixed evenly until completely dissolved to obtain the test sample.

[0093] Experiment 3 A number of female volunteers aged 30-40 were recruited, with each group of 10 people. The volunteers were divided into groups and used the test samples prepared from the deep moisturizing composition containing the baobab leaf extract of each embodiment and comparative example once a day in the morning and evening. After cleansing the face with a disposable face towel and clean water, 5 ml of the test sample was evenly applied to the face and massaged until completely absorbed.

[0094] Before starting the experiment, volunteers used a disposable face towel and clean water to cleanse their faces. After waiting for 30 minutes, the skin moisture content was tested and recorded as the initial skin moisture content before skin care.

[0095] After using the test sample continuously for 30 days, the test was conducted on the 31st day. The volunteers used a disposable face towel with clean water to cleanse their faces, then took 5 ml of the test sample, applied it evenly on the face, and massaged until it was completely absorbed. After waiting for 30 minutes, the skin moisture content was tested. After 8 hours of normal activities, the skin moisture content was tested again. The results were recorded as the initial skin moisture content 30 days after skin care and the skin moisture content 8 hours after 30 days of skin care, respectively.

[0096] The experimental data of each group were averaged.

[0097] The specific test data of Experiments 1-3 are shown in Table 1.

[0098] Table 1 According to the data comparison of each embodiment and comparative example in Table 1, the hyaluronidase inhibition rate of each embodiment is significantly higher than that of each comparative example, the DPPH free radical scavenging rate of each embodiment is significantly higher than that of each comparative example, and the skin moisture content of each embodiment after 8 hours is significantly higher than that of each comparative example. It can be seen that the deep moisturizing composition containing the baobab leaf extract of each embodiment can better repair the skin, increase the hyaluronic acid content in the skin, and better restore the vitality of the skin, thereby significantly improving the water-locking and moisturizing performance of the skin. Since the water-locking and moisturizing performance is derived from the skin itself, the skin can maintain a high moisture content for a longer time, making the moisturizing effect more lasting.

[0099] Each comparative example uses extracts with moisturizing effects to replace the baobab leaf extract, Dendrobium officinale extract, Selaginella extract, and lotus extract in the examples alone or in whole. The hyaluronidase inhibition rate, DPPH free radical scavenging rate, and skin moisture content after 8 hours of each comparative example are significantly lower than those of the examples, proving that only the special combination of baobab leaf extract, Dendrobium officinale extract, Selaginella extract, and lotus extract can significantly improve the hyaluronidase inhibition rate and DPPH free radical scavenging rate, thereby repairing the skin more comprehensively and thoroughly to achieve a more significant and long-lasting moisturizing effect.

[0100] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of the claims of the present application, they are protected by the patent law.
