Description

TECHNICAL FIELD

[0001] The present application relates to the field of skin care raw materials, in particular to a moisturizing and hydrating composition and a preparation method thereof. BACKGROUND

[0002] In the cosmetic and skin care market, moisturizing products always occupy an important position. The water content of the skin directly affects the health and appearance of the skin, and keeping the skin adequately moisturized can make the skin appear smooth, soft and elastic.

[0003] Many traditional moisturizing products have a single moisturizing mechanism. Common moisturizing agents such as glycerol mainly prevent water evaporation by forming a water film on the skin surface. But this single moisturizing method has limited effect, and it is difficult to enhance the skin's own moisturizing ability, resulting in short-lasting moisturizing effect, and the skin will quickly become dry again in a short time.

[0004] Moreover, although the traditional moisturizing agent forms a protective layer on the skin surface, it lacks sunscreen effect, and the skin condition deteriorates rapidly under ultraviolet radiation, further shortening the moisturizing effect and making it difficult to achieve long-lasting moisturizing effect, so there is still room for improvement. SUMMARY

[0005] In order to have long-lasting moisturizing and good sunscreen effect, the present application provides a moisturizing and hydrating composition and a preparation method thereof.

[0006] In a first aspect, the present application provides a moisturizing and hydrating composition, which adopts the following technical solution: A moisturizing and hydrating composition, comprising the following components by mass fraction: 89.1-90.9 parts of moisturizing agent; 0.9-1.1 parts of antibacterial agent; 8.2-9.8 parts of composite plant extract; The composite plant extract is a composite of Gotu Kola leaf extract, Fucus vesiculosus extract, Impatiens balsamina flower extract, Kakadu plum extract and Selaginella uncinata extract.

[0083] Experiment 1 A number of volunteers are tested for the moisturizing and hydrating effects of each example and comparative example.

[0084] Test sample: 10 g of the moisturizing and hydrating composition, 90 g of deionized water, mixed uniformly to obtain the test sample.

[0085] Each group of 10 volunteers, the experimental data of each group was averaged.

[0086] The volunteers cleaned their faces with clean water and a one-time facial wipe, waited for 30 min, measured the skin moisture content, recorded as the initial skin moisture content, then applied 3 mL of the test sample evenly on the face, waited for 30 min, measured the skin moisture content on the cheeks, recorded as the skin moisture content after 30 min of hydration, and then measured the skin moisture content on the cheeks again after 12 h of free activity, recorded as the skin moisture content after 12 h.

[0087] When detecting the skin moisture content, the skin moisture meter Corneometer CM825 was used to detect the skin on the face, and the higher the measured value, the higher the skin moisture content.

[0088] Experiment 2 According to the eighth chapter of the 2015 edition of the "Cosmetic Safety Technical Specifications", the sunscreen efficacy of each example and comparative example was detected by the sunscreen index (SPF value) determination method.

[0089] Test sample: 10 g of the moisturizing and hydrating composition, 90 g of deionized water, mixed uniformly to obtain the test sample.

[0090] Each group of 10 volunteers, the experimental data of each group was averaged.

[0091] The skin type of the subjects was type III.

[0092] The specific experimental data of experiment 1-2 is shown in Table 1.

[0093] Table 1 According to the comparison of the data of each example and comparative example in Table 1, the skin moisture content after 30 min of hydration of each example and comparative example was relatively high, it can be seen that each example and comparative example had the effect of rapid hydration, but the skin moisture content after 12 h of each example was significantly lower than that of each example, it can be seen that the effect of long-term moisturizing of each comparative example was significantly worse than that of the examples, which proved that the combination of the extract of snowbell leaf, the extract of chondrus crispus, the extract of balsam flower, the extract of australian kakadu plum, and the extract of selaginella tamariscina in each example could well regulate the skin and activate the function of the skin to absorb water, so that the skin moisturizing effect was relatively long-lasting.

[0094] In addition, the SPF values ​​of each embodiment are significantly higher than those of the comparative proportions. It can be seen that the combination of Centella asiatica leaf extract, Fucus vesiculosus extract, Impatiens balsamina flower extract, Kakadu plum extract, and Selaginella tamariscina extract in each embodiment can not only improve the moisturizing effect, but also provide better sun protection, better protect the skin, reduce skin damage, and thus keep the skin healthy and moisturized for a long time, reducing skin discomfort.

[0095] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
