Description

Technical Field

[0001] The invention relates to the technical field of cosmetics, and in particular to a moisturizing and repairing water with mood-soothing effect and a preparation method thereof. Background Art

[0002] As the pace of modern life continues to accelerate, people are facing increasing pressure, and emotional problems have gradually become an important factor affecting physical and mental health. Being in a negative emotional state such as tension and anxiety for a long time will not only put a burden on the mind, but will also be reflected in the skin condition at the physiological level. For example, negative emotions may cause dryness, sensitivity, dullness and other problems on the skin, and will also affect the skin's self-repair ability and metabolism. In the field of cosmetics, consumers' demand for products is no longer limited to traditional moisturizing, whitening, anti-wrinkle and other effects. More and more people are beginning to pay attention to the soothing effect of cosmetics on emotions.

[0003] Although there are many moisturizing and repairing water products on the market, they are often insufficient in soothing emotions. On the one hand, many products focus on external skin care in terms of ingredient design, but ignore the regulation of emotions. For example, some products may only focus on the addition of moisturizing factors to achieve skin moisture retention, but fail to take into account the psychological feelings of consumers during use. On the other hand, the smell and skin feel design of the products also fail to fully meet consumers' needs for emotional relief. Some products may have pungent and unnatural smells, which cannot bring consumers a pleasant olfactory experience; and in terms of skin feel, they may be greasy, heavy, and difficult to absorb, affecting the comfort of use. In addition, the synergy of the efficacy of existing moisturizing and repairing water products needs to be improved. Often, they only pursue a certain efficacy, but fail to organically combine multiple functions such as moisturizing, repairing, and soothing emotions, and cannot provide consumers with a full range of skin care solutions.

[0004] In summary, in order to meet consumers' demands for cosmetics in terms of soothing emotions, moisturizing and repairing, and good usage experience, it is of great practical significance to develop a moisturizing and repairing water with soothing emotion effect and a preparation method thereof. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides a moisturizing and repairing water with soothing effect and a preparation method thereof. The present invention achieves soothing from multiple aspects such as smell and touch through a unique formula design and preparation process, and at the same time has excellent skin care effects such as moisturizing and repairing, solving the problems in the background technology.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A moisturizing and repairing water with a soothing effect, comprising the following components by mass percentage:

[0008] Odor regulating composition B 2.5%-3.5%;

[0012] Preferably, the skin feel regulating composition A is a moisturizer, a chelating agent, a thickener, a preservative and a penetration enhancer in a mass ratio of 9:0.02:0.13:0.95:0.3.

[0013] Preferably, the moisturizer is selected from alcohol moisturizers, hyaluronic acid, sodium polyglutamate, and amino acid moisturizers. More preferably, the moisturizer is one or a combination of glycerol, butylene glycol, 4D hyaluronic acid, sodium polyglutamate, and betaine.

[0014] Preferably, the chelating agent is disodium ethylenediaminetetraacetate (EDTA-2Na).

[0015] Preferably, the thickener comprises polyacrylate crosspolymer-6 and hydrolyzed sclerotium gum.

[0016] Preferably, the preservative is selected from p-hydroxyacetophenone, 1,2-hexanediol, and ethylhexylglycerin.

[0017] Preferably, the penetration enhancer is bis-diethoxydiglycol cyclohexane 1,4-dicarboxylate.

[0018] Preferably, the odor regulating composition B is an extract of ophiopogon japonicus and rhamnose.

[0019] Preferably, the plant small molecule polysaccharides are oat beta glucan and algae oligosaccharides. Among them, the manufacturer of oat beta glucan is Shanghai Zhina Biotechnology Co., Ltd., and the product name is F035 small molecule oat beta glucan. The manufacturer of algae oligosaccharides is Lannao Technology (Xiamen) Co., Ltd., and the product name is NEOAOS Hypoglycan. TM .

[0020] Preferably, the plant extract is hydrolyzed lupin protein, chicory root extract, or giant kelp extract.

[0021] Preferably, the skin conditioning composition C is oat beta glucan, algae oligosaccharides, niacinamide, acetyl glucosamine, allantoin, hydrolyzed lupine protein, chicory root extract, and giant kelp extract.

[0022] Preferably, the pH of the wet repair water is 5.5-6.

[0023] Among them, a moisturizing and repairing water with a soothing effect includes the following ingredients by mass percentage:

[0024]

[0025]

[0026] The preparation method of the above-mentioned moisturizing and repairing water with soothing effect comprises the following steps:

[0027] (1) Deionized water, disodium ethylenediaminetetraacetic acid, polyacrylate cross-linked polymer-6, hydrolyzed sclerotium gum, glycerol, butylene glycol, small molecule oat β-glucan, betaine, and allantoin are mixed, heated to 80-85° C., stirred to dissolve until there are no particles, kept warm for 30 minutes, and then cooled, which is recorded as phase A;

[0028] (2) Cool phase A to 65-70°C, add bis-diethoxydiglycol cyclohexane 1,4-dicarboxylate, ethylhexylglycerol, p-hydroxyacetophenone, and 1,2-hexanediol, keep warm for 10 minutes, and stir to dissolve completely without particles.

[0029] (3) When the temperature of the reaction solution obtained in step (2) drops below 45° C., sodium polyglutamate, hydrolyzed lupine protein, chicory root extract, kelp extract, 4D hyaluronic acid, algal oligosaccharides, niacinamide, acetyl glucosamine, kelp flower extract, and rhamnose are added in sequence, and stirred until the solution is completely dissolved without particles and is clear and transparent, thereby obtaining a moisturizing repair water with a soothing effect.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] The moisturizing and repairing water of the present invention has the texture of essence water, has strong fluidity, is refreshing and not stuffy when applied, fits the skin, and brings an instant soft and smooth touch. It has a fast absorption speed and can enhance the sense of pleasure from the sense of touch. In terms of smell, the selected waterless vacuum condensation extracted Dai Dai cell fluid has a purer and more natural smell than the pure dew or essence obtained by steam distillation. At the same time, it cooperates with rhamnose to correct the smell brought by other raw materials, thereby creating a fresh and high-grade fragrance to soothe and relax the body and mind. This sensory experience can effectively relieve the tension of the user and soothe the mood from multiple dimensions of smell and touch.

[0032] The invention adopts multiple ingredients to work synergistically, and has significant effects. Multiple hyaluronic acids achieve layer-by-layer moisturizing, providing lasting moisture to the skin. The oat β-glucan used in this patent has a molecular weight of less than 10000Da, and the β-(1-3) and β-(1-4) glycosidic bonds β-D pyranose glucose units are connected by β-(1-3) and β-(1-4) glycosidic bonds, containing about 70% β-(1-4) bonds and 30% β-(1-3) bonds. It is an unbranched linear polysaccharide that can increase the expression of FLG and Caspase-14 in keratinocytes, promote the production of NMF (natural moisturizing factor), promote endogenous moisturizing, and maintain skin barrier health; the algae oligosaccharides used in this patent have a molecular weight of less than 1000Da, with β-D-galactose and 3-6-endoether-α-L galactose as monosaccharide units, and β-1,4 and α-1,3 glycosidic bonds as linking bonds arranged regularly. In addition to promoting FLG expression, it can also promote the expression of aquaporin AQP3 and tight junction protein ZO-1 of human epidermal fibroblasts. Therefore, the two small molecule polysaccharides can synergistically moisturize and repair the barrier function. In addition, both small molecule polysaccharides have the function of protecting the skin from ultraviolet damage and repairing after sun exposure. Moreover, both small molecule polysaccharides have certain antioxidant properties, and algal oligosaccharides can also inhibit the melanin-promoting factor α-MSH and inhibit the activity of tyrosinase. Therefore, the two small molecule polysaccharides synergize in multiple pathways to moisturize, repair, soothe, and brighten the skin. Betaine balances the osmotic pressure and skin pH, giving the skin a soft feeling, allantoin soothes skin sensitivity, acetyl glucosamine can not only inhibit the activity of tyrosinase, but also promote endogenous moisturizing and regulate keratin metabolism, and rhamnose not only corrects the taste, but also promotes the release of β-endorphin, further soothing the mood. These ingredient combinations provide comprehensive care for the skin, meeting consumers' dual needs for emotional skin care and skin health. BRIEF DESCRIPTION OF THE DRAWINGS

[0063]

[0064]

[0065] The preparation method of the moisturizing repairing water in Example 1 comprises the following steps:

[0066] (1) Deionized water, disodium ethylenediaminetetraacetic acid, polyacrylate cross-linked polymer-6, hydrolyzed sclerotium gum, glycerol, butylene glycol, small molecule oat β-glucan, betaine, and allantoin are mixed, heated to 80-85° C., stirred to dissolve until there are no particles, kept warm for 30 minutes, and then cooled, which is recorded as phase A;

[0067] (2) Cool phase A to 65-70°C, add bis-diethoxydiglycol cyclohexane 1,4-dicarboxylate, ethylhexylglycerol, p-hydroxyacetophenone, and 1,2-hexanediol, keep warm for 10 minutes, and stir to dissolve completely without particles.

[0069] The preparation methods of Comparative Examples 1-9 are the same as those of Example 1.

[0070] The moisturizing and repairing water prepared in Example 1 and Comparative Examples 1-7 were subjected to a sensory test. The test process was as follows: 15 suitable subjects were selected, the examples and comparative examples were randomly sorted, each sample was applied to the same part of the subject, and a sensory evaluation was performed 30 minutes after the application. The results are shown in Table 3.

[0071] Table 3 Sensory evaluation index table of Example 1 and Comparative Examples 1-7

[0072]

[0073] annotation:

[0074] (1) Spreadability: mainly refers to whether the product is easy to spread during application. The higher the value, the higher the degree of spread. The evaluation value is 1-9 points;

[0075] (2) Permeability (absorbability): refers to whether the skin care product is easily absorbed during use. The higher the value, the higher the permeability (absorbability). The evaluation value is 1-9 points;

[0076] (3) Refreshing: refers to the degree to which the skin feels refreshed, non-greasy, and non-stuffy during use. The higher the value, the higher the refreshing degree. The evaluation value is 1-9 points;

[0077] (4) Moisturizing: refers to the degree to which the skin feels moisturized and hydrated after use. The higher the value, the higher the moisturizing degree. The evaluation value is 1-9 points.

[0078] (5) Stickiness during use: refers to the degree of stickiness of the product during use. The higher the value, the lower the stickiness. The evaluation value is 1-9 points.

[0079] (6) Stickiness after use: refers to the degree of stickiness of the product 1 minute after use. The higher the value, the lower the stickiness. The evaluation value is 1-9 points;

[0080] (7) Texture: refers to the overall skin feel of the product experienced through touch when using the product. The higher the value, the higher the texture. The evaluation value is 1-9 points;

[0081] (8) Softness during use: refers to the degree to which the skin feels soft when using the product. The higher the value, the softer the skin feels during use. The evaluation value is 1-9 points;

[0082] (9) Softness during use: refers to the degree of softness felt on the skin 3 minutes after using the product. The higher the value, the softer the skin feels after use. The evaluation value is 1-9 points;

[0083] (10) Smell preference: The degree to which the subject likes the smell of the product during use. The higher the value, the higher the preference after use. The evaluation value is 1-9 points.

[0084] In order to make the difference between the embodiment and the comparative example more intuitive, a radar chart of the evaluation index data was made using EXCEL. The results are as follows: Figure 1-7 shown.

[0085] from Figure 1 It can be seen that compared with Comparative Example 1, Example 1 has significantly improved moisturizing and spreadability, softness and stickiness during and after use, and the test subjects evaluated that the texture increased, and the other differences are small.

[0086] from Figure 2 It can be seen that compared with Comparative Example 2, Example 1 has increased moisturizing and spreadability, increased softness and stickiness during and after use, and increased texture evaluation by the subjects, and the rest of the differences are small.

[0087] from Figure 3 It can be seen that compared with Comparative Example 3, Example 1 has increased moisture retention and absorbency, and the softness before and after use is increased.

[0088] from Figure 4 It can be seen that compared with Comparative Example 4, Example 1 has improved moisturizing properties and softness before and after use, and the test subjects evaluated that the texture was increased.

[0089] from Figure 5 It can be seen that compared with Example 1, the moisturizing property, absorbency, spreadability, softness before and after use, and stickiness of Comparative Example 5 are significantly reduced, and the refreshing property is improved, but the test subjects evaluate the texture as low.

[0090] from Figure 6 , 7It can be seen that, compared with Example 1, the difference in touch index of Comparative Examples 6-7 is smaller, but the evaluation of odor preference has decreased. The sensory evaluation of the subjects shows that the polyacrylate cross-linked polymer-6 in the formula gives the product consistency, making the product more textured, and this consistency can increase the moisture retention and spreadability of the aqueous product. As an extracellular polysaccharide biopolymer, hydrolyzed sclerotium gum can not only slightly increase the consistency of the formula, but also has the characteristics of being thick but not sticky, slippery but not greasy, and can bring a smooth and comfortable skin feel. The use of polyacrylate cross-linked polymer-6 in the formula can improve the product's moisture retention, spreadability, stickiness before and after use, and texture in multiple dimensions. Bis-diethoxydiglycol cyclohexane 1,4-dicarboxylate is an amphiphilic penetration enhancer. In addition to having the effect of promoting the penetration of active ingredients, as a non-ionic surfactant and oil, it can give the formula a moisturizing and quickly absorbed skin feel, and can also reduce the overall stickiness of the formula. When betaine is added to the formula, it can bring an instant and long-lasting soft skin feel. The aster flower extract in the formula is made from carefully selected aster cell fluid extracted by waterless vacuum condensation. It has a pure and natural scent. It can also work synergistically with rhamnose to correct the odors brought by other ingredients, thereby creating a fresh and sophisticated aroma that soothes and relaxes the body and mind.

[0091] The moisturizing and repairing effects of the moisturizing and repairing water were evaluated. The test method was based on QB / T 4256-2011. The 6-hour stratum corneum moisture content test and the 6-hour transepidermal water loss rate test were used to evaluate the moisturizing and repairing effects of the product. The results are as follows: Figure 8-9 shown.

[0092] Compared with the blank sample, the moisture content of the stratum corneum in the test area of ​​Example 1, Comparative Example 8 and Comparative Example 9 after 6 hours of use was significantly increased. And the improvement rate of Example 1 after 6 hours was significantly greater than that of Comparative Example 8 and Comparative Example 9, indicating that the moisturizing repair water has the effect of moisturizing, and also indicates that oat beta glucan and algae oligosaccharides can synergistically improve the moisturizing performance of the formula, while improving the effect of long-term moisturizing. Compared with the blank sample, the transepidermal water loss rate of the skin in the test area of ​​Example 1, Comparative Example 8 and Comparative Example 9 after 6 hours of use was significantly reduced, and the decline rate of Example 1 after 6 hours (the percentage of the same position after application compared to before application) was -24.6%, which was greater than that of Comparative Example 8 (-21.4%) and Comparative Example 9 (-16.6%), indicating that the moisturizing repair water has the effect of repairing, and also indicates that oat beta glucan and algae oligosaccharides can synergistically improve the repair performance of the formula.

[0093] The mood-relief effect of Example 1 was evaluated by using three schemes: a questionnaire survey on the subjects' self-assessment satisfaction, a sleep quality improvement monitoring and statistics, and a mood stress monitoring scheme.

[0094] Questionnaire test plan: 15 subjects were surveyed after using the moisturizing repair water involved in Example 1 once in the morning and once in the evening. The evaluation indicators are as shown in the table. The satisfaction rating was very dissatisfied, dissatisfied, average, satisfied, and very satisfied. The rating of satisfied or very satisfied was counted. The satisfaction rate of the subjects for the moisturizing repair water involved in Example 1 was calculated, as shown in Table 4.

[0095] Table 4 Results of the self-assessment satisfaction survey of the subjects

[0096]

[0097] After using the product for 2 weeks, the self-evaluation results of the subjects showed that Example 1 achieved a 100% satisfaction rate in the evaluation of skin feel and the evaluation of the effect of improving skin moisture, indicating that Example 1 performed well in these aspects, and the subjects were very satisfied with the direct use experience of Example 1. The satisfaction rate of Example 1 in the evaluation of the effect of brightening skin tone and improving dullness was 93.30%, which is a very high satisfaction rate, indicating that Example 1 has a significant effect in brightening skin tone, but there is still a small room for improvement. Example 1 achieved a satisfaction rate of 93.30% and 100% in the evaluation of the overall smell and the evaluation of natural smell and no odor, respectively, indicating that the subjects are very satisfied with the smell of the product, and the smell design of Example 1 meets the expectations of users. The satisfaction rate of Example 1 in making the subjects feel relaxed is 80%, which shows that most subjects feel relaxed after using the product, but 20% of the subjects may not have this experience, indicating that the effect of the formula in improving mood has certain fluctuations. The satisfaction rate of Example 1 in improving sleep quality was 66.70%, which means that more than two-thirds of the subjects believed that Example 1 helped improve sleep quality, but a considerable number of subjects still did not feel this effect. The satisfaction rate of the subjects wanting to increase the frequency of skin care after use was 93.30%, indicating that the product can effectively motivate the subjects to increase the frequency of skin care, which is a positive market feedback.

[0098] In general, the patented moisturizing and repairing water with soothing effects has excellent overall performance, especially in terms of skin feel, moisturizing, brightening, and scent experience, which has been highly recognized by the subjects. The effects of the product in mood management and sleep quality improvement have also been recognized by most subjects, but there is still room for improvement in these aspects.

[0099] For the patented moisturizing and repairing water with soothing effects, monitoring and statistics on sleep quality improvement are conducted. The scheme is as follows:

[0100] The subjects wore a Huawei smartwatch (model GT5 series) and recorded the sleep quality for one week without using Example 1. Then, they used the moisturizing and repairing water designed in Example 1 half an hour before going to bed and half an hour after getting up for one week, and recorded the sleep quality for one week. The average wakefulness time, average rapid eye movement sleep, average core sleep and average deep sleep were monitored, counted and evaluated, and the results are shown in Table 5.

[0101] Table 5 Statistics of sleep quality before and after using moisturizing repair water

[0102]

[0103]

[0104] Generally speaking, improvement in sleep quality can be considered from a variety of perspectives. Here we will use the following more intuitive criteria to make a rough judgment (only for this analysis; judging improvement in sleep quality in actual situations is more complicated):

[0105] Awake time: The awake time is reduced after use, which means better sleep continuity, which can be regarded as a manifestation of improved sleep quality.

[0106] Rapid eye movement sleep, core sleep time, deep sleep time: the sleep time of these three stages increases after use, which can be considered to have a positive effect on improving sleep quality. As long as the duration of at least one of these three indicators increases, and there is no obvious adverse change in the awake time (such as a significant increase, etc.), it can be preliminarily judged that the sleep quality has an improving trend.

[0107] The specific analysis of each individual situation is as follows:

[0108] No. 1: The awake time increased from 20 minutes to 24 minutes, but REM sleep increased from 56 minutes to 64 minutes, core sleep time increased from 144 minutes to 168 minutes, and deep sleep time increased from 72 minutes to 80 minutes. Overall, although the awake time increased, the duration of other sleep stages increased, so it can be considered that the sleep quality has improved.

[0109] No. 2: The wakefulness time decreased from 16 minutes to 12 minutes, REM sleep decreased from 48 minutes to 40 minutes, core sleep time decreased from 120 minutes to 112 minutes, and deep sleep time decreased from 64 minutes to 64 minutes (unchanged). Overall, the reduction in wakefulness time is positive, but the last three indicators have decreased or remained the same. Taking all factors into consideration, it is not yet determined that the sleep quality has improved (because the overall length of the last three sleep stages has not shown a positive trend of change).

[0110] No. 3: The awake time increased slightly from 28 minutes to 32 minutes, REM sleep increased from 72 minutes to 80 minutes, core sleep time decreased from 160 minutes to 144 minutes, and deep sleep time increased from 88 minutes to 104 minutes. Taking all factors into consideration, it can be considered that the sleep quality has improved due to the increase in REM sleep and deep sleep time.

[0111] No. 4: The awake time decreased from 8 minutes to 4 minutes, REM sleep decreased from 64 minutes to 56 minutes, core sleep time decreased from 200 minutes to 176 minutes, and deep sleep time increased from 112 minutes to 120 minutes. Overall, the awake time decreased and the deep sleep time increased, which can be judged as an improvement in sleep quality.

[0112] No. 5: The awake time increased slightly from 36 minutes to 40 minutes, rapid eye movement sleep decreased from 88 minutes to 72 minutes, core sleep time increased from 152 minutes to 208 minutes, and deep sleep time increased from 96 minutes to 128 minutes. Taking all factors into consideration, it is judged that the sleep quality has improved due to the increase in core sleep time and deep sleep time.

[0113] No. 6: The awake time increased slightly from 24 minutes to 28 minutes, rapid eye movement sleep decreased from 80 minutes to 64 minutes, core sleep time decreased from 184 minutes to 168 minutes, and deep sleep time decreased from 104 minutes to 112 minutes (unchanged). Overall, the latter three indicators did not show a positive trend as a whole, and it is not yet judged that the sleep quality has improved.

[0114] No. 7: The awake time increased slightly from 16 minutes to 20 minutes, REM sleep decreased from 72 minutes to 48 minutes, core sleep time increased from 144 minutes to 200 minutes, and deep sleep time increased from 80 minutes to 88 minutes. Taking all factors into consideration, it is judged that the sleep quality has improved due to the increase in core sleep time and deep sleep time.

[0115] No. 8: The wakefulness time was reduced from 12 minutes to 8 minutes, REM sleep was reduced from 40 minutes to 32 minutes, core sleep time was reduced from 128 minutes to 112 minutes, and deep sleep time was reduced from 72 minutes to 64 minutes. Overall, although the wakefulness time was reduced, the last three indicators were also reduced, so it is not yet possible to judge that the sleep quality has improved.

[0116] No. 9: The awake time increased slightly from 32 minutes to 36 minutes, REM sleep increased from 48 minutes to 56 minutes, core sleep time decreased from 160 minutes to 144 minutes, and deep sleep time decreased from 96 minutes to 80 minutes. Overall, although REM sleep increased, the latter two indicators decreased, and it is not yet possible to judge that the sleep quality has improved.

[0117] No. 10: The awake time increased slightly from 44 minutes to 48 minutes, REM sleep increased from 64 minutes to 72 minutes, core sleep time decreased from 176 minutes to 152 minutes, and deep sleep time decreased from 120 minutes to 104 minutes. Overall, although REM sleep increased, the latter two indicators decreased, and it is not yet possible to judge that the sleep quality has improved.
