Description

Technical Field

[0001] The invention relates to the technical field of cosmetics, and in particular to a temperature-sensitive refreshing and moisturizing gel spray and a preparation method thereof. Background Art

[0002] As consumers' demand for skin care continues to increase, moisturizing spray, as a convenient and efficient skin care product, has gradually gained favor in the market. With its unique spray form, moisturizing spray can quickly replenish moisture to the skin and relieve dry skin. At the same time, its portability also meets consumers' needs for skin care anytime and anywhere. In recent years, with the continuous advancement of technology and the diversification of consumer demand, the moisturizing spray market has shown a rapid growth trend.

[0003] Traditional moisturizing sprays are mainly in liquid form, which can quickly provide the skin with the required moisture and achieve an immediate hydrating effect. However, this type of spray is not good in terms of moisturizing durability and often cannot maintain the skin's hydration for a long time. More importantly, due to the formula limitations of traditional sprays, it is usually impossible to add suspending agents to stabilize the active ingredients. Therefore, after being left for a long time, some active ingredients may precipitate due to insufficient suspension, which not only gives a bad impression in terms of sensory perception, but also directly affects the use effect and uniformity of the spray.

[0004] A new type of spray has appeared on the market, which uses water-soluble polymer materials such as poloxamer, polyvinyl alcohol, polyacrylic acid, sodium polymethacrylate hyaluronic acid, sodium alginate, chitosan, etc. as thickeners. This spray has excellent suspension performance, can ensure the uniformity and stability of the material body, can effectively prolong the moisturizing effect, and avoid the appearance discrepancy caused by precipitation. Although this spray performs well in stability and moisturizing, when the spray is sprayed on the skin surface after atomization, a layer of adhesive hydrogel-like wet film will be formed on the skin. Although it helps to lock in moisture, the skin feels sticky. In addition, since the gel spray has a certain consistency before the addition of the functional raw materials, it increases the difficulty of dispersion in the process to a certain extent. During the preparation process, how to ensure that the functional raw materials are evenly dispersed in the gel material body has become a challenge. At the same time, due to the difficulty of dispersion, the semi-finished material body finally made often contains more bubbles, which not only affects the appearance of the product, but also has a certain negative impact on the use effect of the product. Summary of the invention

[0005] The purpose of the present invention is to overcome the shortcomings and deficiencies of the prior art and provide a temperature-sensitive refreshing moisturizing gel spray and a preparation method thereof. The temperature-sensitive refreshing moisturizing gel spray provided by the present invention not only has good instant hydration and long-lasting moisturizing effects, is mild and non-irritating, and feels refreshing and non-greasy on the skin, but also has excellent suspension performance, and the material body is uniform and stable. The preparation process is simple, fast and efficient, no bubbles are generated, the material body has a good appearance, and the spraying is uniform, which improves the use experience.

[0006] To achieve the above object, the present invention provides the following technical solutions.

[0007] A temperature-sensitive refreshing moisturizing gel spray, the gel spray comprising the following components: Phase A: 0.1%-0.3% gellan gum, 1%-8% butanediol, appropriate amount of deionized water; Phase B: 0.2%-0.4% p-hydroxyacetophenone, 0.2%-0.4% hexylene glycol, 0.2%-0.4% betaine; Phase C: 1%-5% rose water, 0.2%-1.2% glyceryl glucoside, 1%-5% cactus extract, 1%-15% peony fermentation filtrate, 0.01%-0.1% carboxymethyl deacetylated chitosan.

[0008] A method for preparing the gel spray as described above specifically comprises: S1: Mix and disperse phase A evenly, and heat to 80-85℃; S2: Cool down to 60-65℃, add phase B, mix and disperse evenly; S3: Cool down to 45-50℃, add phase C, mix and disperse evenly; S4: Fill at 45±2℃.

[0009] The present invention uses gellan gum with unique temperature-sensitive properties as the core thickening ingredient. It exhibits good fluidity at high temperatures and is in liquid water form. It is easy to mix and disperse with other ingredients, and the process operation is simple. When the temperature drops to 35-40°C, the gellan gum turns into a gel state, showing excellent suspension retention ability for various functional extracts, ensuring long-term stability, effectively improving the overall quality and effect of the product, and no bubbles are generated during the process operation from high temperature to low temperature, making the appearance of the material more excellent. In addition, gellan gum also has an important physical property—it can be shear-thinned. When sheared through the nozzle of a spray bottle, it can form a delicate and uniform spray, which is easy to use, sprayed evenly, and feels refreshing and non-sticky on the skin.

[0010] Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention provides a temperature-sensitive refreshing moisturizing gel spray, which has good instant hydration and long-lasting moisturizing effects, is mild and non-irritating, and feels refreshing and non-sticky on the skin; (2) The present invention provides a temperature-sensitive refreshing moisturizing gel spray, which is in the form of a flowing liquid at high temperature, is easy to disperse, is easy to operate, and has high production efficiency; it is in the form of a gel at low temperature, has excellent suspension performance, and the material body is uniform and stable; no bubbles are generated during the process operation, and the material body has a good appearance; (3) The present invention provides a temperature-sensitive refreshing moisturizing gel spray, which is packaged in an ordinary spray bottle and can achieve a fine spray effect. It is easy to use and sprays evenly. DETAILED DESCRIPTION

[0011] The present invention provides a temperature-sensitive refreshing moisturizing gel spray and a preparation method thereof. To make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0012] A temperature-sensitive refreshing moisturizing gel spray, composed of the following components by weight percentage, the contents of Examples 1-3 are shown in Table 1 below:

[0013] Comparative Example 1: The difference from Example 2 is that in this comparative example, the gellan gum is 0.05%;

[0014] Comparative Example 2: The difference from Example 2 is that there is no gellan gum in this comparative example;

[0015] Comparative Example 3: The difference from Example 2 is that in this comparative example, the amount of carboxymethyl chitosan is 0.2%;

[0016] Comparative Example 4: The difference from Example 2 is that an equal amount of sodium alginate is used to replace gellan gum in this comparative example;

[0017] Comparative Example 5: The difference from Example 2 is that an equal amount of poloxamer is used to replace gellan gum in this comparative example;

[0018] Comparative Example 6: The difference from Example 2 is that in this comparative example, equal amounts of Carbopol 934 and arginine are used to replace gellan gum;

[0019] The method for preparing the spray described in the embodiments and comparative examples of the present invention comprises the following steps: S1: Mix and disperse phase A evenly, and heat to 80-85℃; S2: Cool down to 60-65℃, add phase B, mix and disperse evenly; S3: Cool down to 45-50℃, add phase C, mix and disperse evenly; S4: Fill at 45±2℃.

[0020] Performance test: The sprays prepared in Examples 1-2 and Comparative Examples 1-6 were tested for the following performances:

[0021] 1. Stability test: Samples of Examples 1-2 and Comparative Examples 1-6 were placed in an environment of -10°C and 45°C, and taken out every week to observe whether there were any abnormalities. The test period was 1 month. After the test period, the test samples were taken out and restored to room temperature (25±2°C), and the appearance of the test samples was observed and recorded. The specific situation is shown in Table 2 below:

[0022] Conclusion: From Table 1, it can be seen that among the 8 samples, the sample of Comparative Example 2 has stratification at -10°C. When there are more plant-based raw materials, the addition of a suspending polymer thickener makes the product more stable. Among the samples, the samples of Comparative Example 4, Comparative Example 5, and Comparative Example 6 all show bubbles in appearance. This is mainly because the polymer thickener has formed a relatively thick gel-like substance under high temperature. When low-temperature raw materials are added, a large number of bubbles will be generated due to the temperature difference and physical property differences. In addition, the uniform dispersion of raw materials also faces certain challenges and risks. The type of thickener and its unique properties have a direct and significant impact on the final appearance of the material.

[0023] 2. Spray atomization effect test: 70 subjects aged 20 to 35 years old were randomly selected, including 35 males and 35 females; and they were randomly divided into 7 groups, each with 10 people; and they were marked as Examples 1-2 and Comparative Examples 1, Comparative Examples 3-6 respectively; Then, the subjects in different groups were asked to use the sprays prepared to match the groups, and each group of subjects was asked to use the sprays of the corresponding group to conduct the spray atomization effect test, and the test data obtained were recorded in Table 3:

[0024] Conclusion: From Table 3, it can be seen that the spraying effect of Comparative Examples 3-4 is not ideal. The type of thickener and its unique properties have a significant impact on the spraying effect, and excessive addition of non-shear-thinning water-soluble polymer materials will affect the spraying effect.

[0025] 3. Refreshing and moisturizing effect test: 50 subjects aged 20 to 35 were randomly selected, including 25 males and 25 females; and randomly divided into 5 groups, each with 10 people; and marked as Examples 1-2 and Comparative Examples 1, 5, and 6 respectively; Then, the subjects in different groups were asked to use the sprays prepared by Examples 1-2 and Comparative Examples 1, 5, and 6 that matched the groups, and the skin moisture content before, 5 minutes, and 4 hours after the spray was used was tested using a tester Corneometer CM825, and the average skin moisture content and skin feel of each group of volunteers were recorded, and the obtained data were recorded in the following Table 4:

[0026] Conclusion: As can be seen from Table 4, the sprays prepared by Examples 1-2 and Comparative Examples 1, 5, and 6 can significantly increase the moisture content of the skin after 5 minutes of use, and have a good instant moisturizing effect. Furthermore, when the spray is used for 4 hours, the skin moisture content of Examples 1-2 and Comparative Examples 5 and 6 is still significantly higher than the level before use; however, the skin moisture content of Comparative Example 1 is relatively low, which indicates that the amount of thickener used has a significant effect on the long-lasting moisturizing performance of the product. In addition, the skin feel of Comparative Examples 5 and 6 after use is relatively sticky, which reflects that the type of thickener and its inherent characteristics have a direct impact on the skin feel in the user experience.

[0027] By comparing and analyzing the relevant data, it can be seen that compared with the comparative example, the temperature-sensitive refreshing moisturizing gel spray prepared by the present invention uses gellan gum as a suspension thickener, so that the material body presents a flowing liquid water state under high temperature, which is easy to disperse, simplifies the operation process, and improves production efficiency. Under low temperature conditions, the material body is transformed into a gel state, showing excellent suspension performance, ensuring that the material body is uniform and stable, and no bubbles are generated during the process operation, ensuring the excellent appearance of the material body; further, the spray can not only achieve a good instant hydration effect, but also has a lasting moisturizing effect, while being gentle and non-irritating, and the skin feels refreshing and non-sticky, which greatly improves the user's experience. In addition, based on the shear-thinning properties of gellan gum, the spray can achieve a fine spray effect even if it is packaged in an ordinary spray bottle, which is more convenient to use and more uniform in spraying.
