Description

Technical Field

[0001] This invention relates to the field of skincare raw materials, and in particular to a multi-effect moisturizing composition, its preparation method, and its application. Background Technology

[0002] Skincare products are products that protect the skin. By using skincare products, one can improve the skin's condition and enhance one's appearance. Furthermore, due to the decreasing production cost of skincare products, they have become a popular consumer product.

[0003] Moisturizing is an important function of skin care. Sufficient moisture in the skin can greatly reduce skin damage and is very beneficial for maintaining skin health. Especially in the dry autumn and winter, when the air moisture content is low, the skin is prone to dryness. Using skin care products with moisturizing effects can effectively reduce the damage to the skin caused by dryness.

[0004] However, existing moisturizing skincare products mainly work by covering the skin surface with hydrophilic materials. These materials actively absorb moisture from the air, enhancing the skin's water absorption capacity and thus resisting moisture loss. While these products do provide moisturizing benefits, the hydrophilic materials are merely a physical coating on the skin. In the natural environment, their function gradually declines due to physical wear and chemical changes. Consequently, existing skincare products typically only provide good moisturizing effects for a short period. Over time, their moisturizing efficacy significantly decreases, requiring frequent reapplication to maintain skin hydration, which is inconvenient. Therefore, there is still room for improvement. Summary of the Invention

[0005] To achieve better long-lasting moisturizing effects, this application provides a multi-effect moisturizing composition, its preparation method, and its application.

[0006] In a first aspect, this application provides a multi-effect moisturizing composition, which adopts the following technical solution: A multi-effect moisturizing composition is formulated from Ophiopogon japonicus root extract, Spirulina macrophylla extract, Panax notoginseng extract, and Prunus japonica seed extract.

[0007] By employing the above-mentioned technical solution, through the synergistic combination of Ophiopogon japonicus root extract, Spirulina macrophylla extract, Panax notoginseng extract, and Prunus japonica seed extract, the multi-effect moisturizing composition, once absorbed by the skin, effectively activates skin activity, making intercellular lipids more abundant. This significantly enhances the skin's own water-locking function, making it difficult for absorbed moisture to be lost. Thus, the skin achieves moisturizing effects from within, without excessively relying on external forces to absorb moisture from the air. Even when the hydrophilic ingredients in skincare products become ineffective, the skin is less prone to moisture loss, thereby greatly improving the longevity of the moisturizing effect and achieving better, more lasting hydration.

[0008] Preferably, the mass ratio of the Ophiopogon japonicus root extract, Spirulina macrophylla extract, Panax notoginseng extract, and Prunus japonica seed extract is 16-20:60-66:6-10:2-4.

[0009] By adopting the above technical solution and specifically selecting the mass ratio of Ophiopogon japonicus root extract, Spirulina macrophylla extract, Panax notoginseng extract, and Prunus japonica seed extract, the synergistic effect of these extracts is enhanced, which can better activate skin activity, improve skin's water retention, and achieve better long-lasting hydration.

[0010] Preferably, the mass ratio of the Ophiopogon japonicus root extract, Spirulina macrophylla extract, Panax notoginseng extract, and Prunus japonica seed extract is 17-19:62-64:7-9:2.5-3.5.

[0011] By adopting the above technical solution and specifically selecting the mass ratio of Ophiopogon japonicus root extract, Spirulina macrophylla extract, Panax notoginseng extract, and Prunus japonica seed extract, the resulting skin care product has a longer-lasting moisturizing effect and effectively reduces the frequency of skin care product application.

[0012] Preferably, the extracts of Ophiopogon japonicus root, Spirulina macrophylla, Panax notoginseng, and Prunus japonica seed are all water-soluble extracts.

[0013] By adopting the above technical solution, and using water-soluble extracts such as Ophiopogon japonicus root extract, Spirulina macrophylla extract, Panax notoginseng extract, and Prunus japonica seed extract, the multi-effect moisturizing composition is easily absorbed by the skin, thereby better activating skin activity, resulting in better skin care effects and a more lasting moisturizing effect.

[0014] Secondly, this application provides a method for preparing a multi-effect moisturizing composition, which adopts the following technical solution: A method for preparing the above-mentioned multi-effect moisturizing composition includes the following steps: Step 1): Add the root extract of Ophiopogon japonicus, Spirulina macrophylla extract, Panax notoginseng extract, and Prunus japonica extract to water, mix well, and obtain the extract. Step 2) Concentrate and dry the extract to obtain a multi-functional moisturizing composition.

[0015] By adopting the above technical solution, the extracts of Ophiopogon japonicus root, Spirulina macrophylla, Panax notoginseng, and Prunus japonica seed are mixed in water, so that the components are mixed in a dissolved state, which allows the components to be fully and evenly mixed and to better cooperate with each other, thereby exerting a better effect of activating skin activity and improving the skin's water-locking ability.

[0016] Preferably, in step 2), the concentration is carried out by rotary evaporation at a temperature of 60-65°C.

[0017] By adopting the above technical solution and controlling the concentration temperature, the activity of each extract can be better maintained, resulting in a multi-effect moisturizing composition with better efficacy and higher quality.

[0018] Thirdly, this application provides an application of a multi-effect moisturizing composition, using the following technical solution: an application of the above-mentioned multi-effect moisturizing composition, in which the multi-effect moisturizing composition is added to skin care products to prepare skin care products with moisturizing effects.

[0019] By adopting the above technical solution and adding the multi-effect moisturizing composition to skin care products, the resulting skin care products can not only cover the skin with hydrophilic raw materials to help the skin absorb moisture from the air, but also activate skin activity, making the intercellular lipids of the skin cells more abundant, thereby greatly increasing the skin's water-locking ability and making the moisturizing effect more lasting.

[0020] Preferably, the amount of the multi-effect moisturizing composition added to the skin care product is 1-10%.

[0021] By adopting the above technical solution and by specifically selecting the amount of multi-effect moisturizing composition added to skin care products, the resulting skin care products have long-lasting moisturizing effects, high safety, and can effectively control costs, thus possessing high economic value.

[0022] In summary, this application has the following beneficial effects: 1. Because this application utilizes the combined effects of Ophiopogon japonicus root extract, Spirulina macrophylla extract, Panax notoginseng extract, and Prunus japonica seed extract, the multi-effect moisturizing composition can effectively activate skin activity after being absorbed by the skin, making the intercellular lipids more abundant. This significantly enhances the skin's own water-locking function, making it difficult for moisture to be lost after being absorbed by the skin. Thus, the skin achieves moisturizing effects from within, without relying excessively on external forces to absorb moisture from the air. Even after the hydrophilic ingredients in skincare products become ineffective, the skin is less prone to moisture loss, thereby greatly improving the longevity of the moisturizing effect and achieving a better long-lasting moisturizing effect.

[0023] 2. In this application, the preferred method is to select the specific mass ratio of Ophiopogon japonicus root extract, Spirulina macrophylla extract, Panax notoginseng extract, and Prunus japonica seed extract to achieve a better synergistic effect, which can better activate skin activity, improve skin's water retention, and achieve better long-lasting moisturization.

[0024] 3. The method of this application involves mixing Ophiopogon japonicus root extract, Spirulina macrophylla extract, Panax notoginseng extract, and Prunus japonica seed extract in water, so that the components are mixed in a dissolved state, thereby ensuring that the components are fully and evenly mixed and can better cooperate with each other to exert a better effect of activating skin activity and improving the skin's water-locking ability.

[0096] Experiment 1 Preparation of test samples: Take 1g of the multi-effect moisturizing composition and 99g of deionized water, mix them evenly until completely dissolved, and obtain the test sample.

[0097] A number of volunteers were recruited, all of whom were women aged 30-35, and the experiment was conducted in groups of 10.

[0098] Volunteers first used disposable face towels and water to wash their faces. After washing, they dried their faces with a clean towel and measured their skin moisture content, recording it as the skin moisture content after washing. Then, without applying any skincare products, they had free time for 1 hour, after which their skin moisture content was measured again and recorded as the 1-hour skin moisture content (blank). They then washed their faces again with disposable face towels and water, dried their faces with a clean towel, and then took 3ml of the test sample, applying it evenly to their faces until the sample was completely absorbed by the skin. They measured their skin moisture content again and recorded it as the skin moisture content after skincare. After 4, 8, and 12 hours of free time, their skin moisture content was measured again and recorded as the skin moisture content after 4 hours, 8 hours, and 12 hours of skincare, respectively.

[0099] When testing skin moisture content, a Corneometer CM825 is used to measure facial skin moisture. The higher the measured value, the higher the skin moisture content.

[0100] The experimental data are taken as the average.

[0101] The specific test data for Experiment 1 are detailed in Table 1.

[0102] Table 1 According to the data comparison between the embodiments and comparative examples in Table 1, the volunteers in the embodiments and comparative examples had similar rates of skin moisture loss when not using skin care products. After using the test samples of the embodiments and comparative examples, the moisturizing effects were similar within 4 hours. In the 4-8 hour stage, the moisturizing effects of the embodiments were significantly higher than those of the comparative examples, and the moisturizing effects of the embodiments were basically not reduced. In the 8-12 hour stage, the moisturizing effects of the embodiments were only slightly reduced, while the moisturizing effects of the comparative examples were greatly reduced to a state of very dry skin.

[0103] It is evident that the multi-effect moisturizing composition prepared by compounding Ophiopogon japonicus root extract, Spirulina macrophylla extract, Panax notoginseng extract, and Prunus japonica seed extract can effectively activate skin activity, significantly improve the skin's water-locking ability, and thus achieve remarkable and long-lasting moisturizing effects.
