Description

Technical Field

[0001] The invention belongs to the technical field of daily cosmetics, and particularly relates to a highly moisturizing bath cream with skin repairing effect and a preparation method thereof. Background Art

[0002] The skin barrier is mainly composed of the sebum membrane and the stratum corneum. It mainly plays the role of maintaining skin moisture, preventing the evaporation of body water, and resisting the invasion of foreign matter into the body.

[0003] The sebum membrane is mainly a mixture of sebum and sweat, covering the surface of our skin with a thickness of only 0.5 microns. Although it is very thin, the sebum membrane plays an important role and can be called a natural moisturizer synthesized by the body itself. The sebum membrane is the most important layer of the skin to lock in moisture, which can effectively lock in moisture; at the same time, it is emulsified from sebum and water, which can effectively moisturize the skin; as the immune layer of the skin epidermis, the sebum membrane can also inhibit the growth of certain microorganisms and has an anti-infection effect.

[0004] The stratum corneum is the "wall" of the skin. The structure of the stratum corneum is relatively simple, consisting of multiple layers of keratinocytes and intercellular lipids. A healthy stratum corneum has a strong ability to retain water.

[0005] A healthy skin barrier must have tightly connected keratinocytes, which can maintain skin moisture in the changing external environment of the four seasons, resist the invasion of foreign matter, and look moist and delicate. However, when the sebum membrane becomes thinner and the stratum corneum is damaged due to external or internal factors, the skin barrier is damaged, and the moisture of the skin begins to flow out in large quantities. External irritants easily penetrate the stratum corneum, and various skin problems will occur. For example, a damaged skin barrier will show that the skin is oily on the outside and dry on the inside, the skin is extremely sensitive, the pores are large and oily, and acne occurs; the skin is prone to aging and red blood streaks appear, the capillaries are directly exposed to the surface of the skin, and red blood streaks appear when the blood vessel walls expand; the skin is dry and peeling, especially dry skin. After the skin barrier is damaged, the water-locking ability decreases, and the skin surface is rough and peeling. Severe damage to the skin barrier can induce a variety of skin diseases, such as atopic dermatitis and psoriasis.

[0006] Damaged skin barrier needs to be repaired in time. Cosmetic repair is a good way to prevent and treat damaged skin barrier. It can repair damaged skin barrier by applying cosmetics with skin repair and other functions. However, most cosmetics currently still focus on beauty effects, and there is little research on skin barrier repair. In addition, products that can achieve skin repair functions in wash-off cosmetics are extremely rare.

[0007] Chinese patent CN113576949A discloses a multi-biomimetic composition, which uses a specific ratio of polyquaternium-51, squalane and sacha inchi oil to simulate the components of the human skin barrier. The composition can repair the skin barrier, reduce water loss, and ensure the structural and functional integrity of the skin barrier. However, polyquaternium contains acrylamide residues (produced during synthesis). Acrylamide monomers have neurotoxic, carcinogenic and teratogenic toxicity to the human body, can pass through the skin and gastrointestinal tract, and can cause various systemic reactions; there are safety issues.

[0008] Chinese patent CN113244151B discloses a soothing repair cream and its preparation method, which contains Kochia scoparia extract, Portulaca oleracea extract, Honeysuckle extract, Duckweed extract, Nepeta extract, Prunus mume extract, ceramide, lecithin, phytosterols and conventional cosmetic excipients. It claims to significantly improve and maintain the moisture content of the skin, soothe the skin, repair the skin barrier, and improve skin tolerance. At the same time, the soothing repair cream has the characteristics of easy absorption, good skin feel, and non-stickiness.

[0009] Chinese patent CN112137921A discloses a soothing anti-allergic composition, its application and soothing anti-allergic facial mask, the soothing anti-allergic composition includes wild walnut extract, flaxseed extract, nepeta extract, Centella asiatica extract, purslane extract, honeysuckle extract, wormwood extract, scutellaria extract, saposhnikovia extract, camellia extract, safflower extract, royal jelly extract, ginkgo extract, burdock extract, Xanthium sibiricum extract, which has certain effects of repairing damaged skin and soothing and calming the skin. However, the soothing effect of the soothing anti-allergic composition is not ideal, and more than a dozen plant extracts in the raw materials may produce adverse reactions and increase the burden on the skin.

[0010] Therefore, it is very important to provide a skin care product that has both moisturizing and water-locking functions and the function of repairing the skin barrier. Summary of the invention

[0011] Based on the deficiencies in the prior art, the present invention aims to provide a highly moisturizing shower cream and a preparation method thereof that can repair the skin barrier, increase the water content of the skin stratum corneum, moisturize and repair the skin, and also take into account the performance of bathing and washing.

[0012] In order to achieve the above object, the present invention adopts the following technical solution:

[0013] A highly moisturizing shower cream with skin repairing effect, comprising the following components by weight:

[0014] 30-40 parts of surfactant, 15-20 parts of thickener, 1-5 parts of suspending agent, 10-20 parts of emulsion stabilizer, 0.1-0.5 parts of chelating agent, 0.1-0.5 parts of humectant, 0.1-0.3 parts of pH adjuster, 0.5-0.8 parts of preservative and 20-40 parts of water.

[0015] in,

[0016] The surfactant is selected from a mixture of sodium lauroyl sarcosinate and water or / and a mixture of cocamidopropyl betaine, sodium chloride and water.

[0017] Preferably, the surfactant is a mixture of sodium lauroyl sarcosinate and water and a mixture of cocamidopropyl betaine, sodium chloride and water, and the mass ratio of the two is 3:0.8-1.2; preferably 3:1.

[0018] The thickener is selected from a mixture of cocamide methyl MEA and glycerol or / and a mixture of lauryl hydroxysulfobetaine, sodium chloride and water;

[0019] Preferably, the thickener is a mixture of cocamide methyl MEA and glycerol and a mixture of lauryl hydroxysulfobetaine, sodium chloride and water, and the mass ratio of the two is 10:2-4; preferably 10:3.

[0020] In some preferred embodiments, the thickener comprises sodium chloride.

[0021] The suspending agent is trihydroxystearin.

[0022] The emulsion stabilizer includes emulsion stabilizer A and emulsion stabilizer B;

[0023] The emulsifier stabilizer A is a mixture of lecithin, caprylic / capric triglyceride, phytosterols, glyceryl stearate, tocopherol acetate and bisabolol, and the mass ratio thereof is 80:10:5:3:1:1.

[0024] The emulsifier stabilizer B is a mixture of glycerol, hydrogenated lecithin and ceramide, and the mass ratio thereof is 65:30:5; the ceramide is a mixture of ceramide NP, ceramide NS, ceramide NG, ceramide AS, ceramide AP and ceramide EOP, and the mass ratio thereof is 4.799998:0.05:0.05:0.1:0.000001:0.000001.

[0025] In some preferred embodiments, the mass ratio of the emulsion stabilizer A to the emulsion stabilizer B is 10:2-5; preferably, the mass ratio of the emulsion stabilizer A to the emulsion stabilizer B is 10:3.

[0026] The components of the emulsion stabilizer described in the present invention are all components that imitate human sebum membranes. By reasonably controlling the specific components of the emulsion stabilizer and the mass ratio between the components, skin nutrients can be better increased, the skin's self-repair ability can be improved, the skin's microcirculation system can be restored, water can be locked in and moisturized, and sebum can be balanced.

[0027] As some preferred embodiments, the mass ratio of the surfactant to the emulsion stabilizer is 1.5-4:1; preferably 3-3.5:1.

[0028] The present invention significantly improves the transdermal effect of the active ingredients by controlling the mass ratio of the surfactant to the emulsifier stabilizer to 1.5-4:1, so that each ingredient can penetrate into the basal layer of the skin in a short time, replenish the skin with homologous inherent ingredients, and allow each cell to be fully moisturized and maintained, so that the effective ingredients can exert better bioavailability, repair damaged skin from the root, improve skin tolerance, delay and improve skin aging, and truly achieve the purpose of skin treatment and beauty.

[0029] The chelating agent is disodium EDTA.

[0030] The moisturizing agent is a mixture of sugar isomers, sodium citrate, citric acid and water.

[0031] The moisturizing agent also includes carboxymethyl chitosan.

[0032] In some preferred embodiments, the mass ratio of the mixture of saccharide isomers, sodium citrate, citric acid and water to carboxymethyl chitosan is 1:1.

[0033] The present invention uses a mixture of carbohydrate isomers, sodium citrate, citric acid and water and carboxymethyl chitosan as moisturizers. The mixed use of these two components can promote the hydration and water retention capacity of the stratum corneum in a short time and improve the problem of skin desquamation. At the same time, the moisturizer component also stimulates the gene expression of silk protein and hyaluronic acid synthase-3, increases the level of NMF and hyaluronic acid, improves the hydration capacity of the skin; stimulates the gene expression of lutein and acid sphingomyelinase, stimulates the synthesis of ceramide, and enhances the structure of the stratum corneum.

[0034] The pH regulator is citric acid.

[0035] The preservative is a mixture of phenoxyethanol, caprylyl glycol and ethylhexylglycerin in a mass ratio of 8:1:1.

[0036] The present invention also provides a method for preparing the highly moisturizing bath cream, comprising the following steps:

[0039] (3) Add the suspending agent, chelating agent, moisturizing agent, pH adjuster and preservative to the mixture B in sequence, and stir at 25 rpm for 30 minutes to obtain the highly moisturizing shower cream.

[0040] Compared with the prior art, the present invention has the following beneficial effects:

[0041] (1) The highly moisturizing shower gel provided by the present invention contains an emulsifier stabilizer, the ingredients of which are all human sebum membrane components, which can better increase skin nutrients, improve the skin's self-repair ability, restore the skin's microcirculation system, lock in moisture and balance sebum; by controlling the mass ratio of surfactant to emulsifier stabilizer to 1.5-4:1, the transdermal effect of the active ingredients is significantly improved, so that each ingredient can penetrate into the basal layer of the skin in a short time, replenish the skin with homologous inherent ingredients, allow each cell to be fully moisturized and maintained, and enable the effective ingredients to exert better bioavailability, repair damaged skin from the root, improve skin tolerance, delay and improve skin aging, and truly achieve the purpose of skin treatment and beauty.

[0042] (2) The present invention uses a mixture of carbohydrate isomers, sodium citrate, citric acid and water and carboxymethyl chitosan as moisturizers. The mixed use of these two components can promote the hydration and water retention capacity of the stratum corneum in a short period of time and improve the problem of skin desquamation. At the same time, the above moisturizer components also increase the levels of NMF and hyaluronic acid and improve the hydration capacity of the skin by stimulating the gene expression of silk protein and hyaluronic acid synthase-3; stimulate the synthesis of ceramide and enhance the structure of the stratum corneum by stimulating the gene expression of lutein and acid sphingomyelinase.

[0043] (3) The present invention reasonably controls various specific ingredients and the mass ratios between the ingredients, so that the highly moisturizing shower cream can effectively repair the skin barrier, increase the water content of the skin's stratum corneum, and has the effect of moisturizing and repairing the skin, while also taking into account bathing and washing.

[0086] Effect Experiment

[0087] 1. Moisture test

[0088] External weighing method for moisturizing performance test: Weigh 0.5g of the sample and apply it evenly on a 5cm×5cm glass plate with microporous ventilation tape, and put the glass plate into a constant temperature and humidity dryer.

[0090] Wherein, M0 is the mass of the glass plate / g, M1 is the mass of the glass plate after adding the sample / g, and M2 is the mass of the glass plate after being placed in the dryer for 8 hours / g.

[0091] The test results are shown in Table 1 below.

[0092] Table 1

[0093]

[0094] According to the test results in Table 1 above, it can be seen that:

[0095] The highly moisturizing shower creams prepared in Examples 1-3 have good moisturizing effects, all of which are above 85%.

[0096] Comparative Example 1-2 reduces one emulsifier stabilizer on the basis of Example 1-3, and the moisturizing effect of the highly moisturizing shower cream prepared therefrom is significantly affected, indicating that the type of emulsifier stabilizer will have a significant impact on the moisturizing effect.

[0097] Comparative Example 3-4 changes the mass ratio of surfactant to emulsifier stabilizer, which is not within the protection scope of the present application and will affect the moisturizing effect of the highly moisturizing shower cream to a certain extent, indicating that the mass ratio of surfactant to emulsifier stabilizer will have a certain influence on the moisturizing effect.

[0098] 2. Repair, soothing and moisturizing effect test

[0116] Subjects' return visit, back cleaning and waiting: Subjects cleaned their backs with cleansing towels dipped in clean water, wiped the skin with dry tissues, and sat in a laboratory at 21±1℃ and 50±10%RH for 30 minutes;

[0117] Skin data collection after test subjects used the samples for 14 days: Laboratory technicians operated Vapometer, Corneometer, and C-CUBE2 instruments to measure relevant indicators on the observed parts of the subjects.

[0118] The specific test results are shown in Table 3 below.

[0119] Table 3

[0120]

[0121] According to the test results in Table 3 above:

[0122] The products prepared in Examples 1-3 are:

[0123] After continuous use for 7 and 14 days, the moisture content of the subjects' stratum corneum increased significantly compared with the baseline value. After continuous use for 7 days, the change rate of the moisture content of the subjects' stratum corneum compared with the baseline was more than 9.6%, and the highest could reach 9.83%; after continuous use for 14 days, the change rate of the moisture content of the subjects' stratum corneum compared with the baseline was more than 29%, and the highest could reach 30.79%.

[0124] After continuous use for 7 and 14 days, the subjects' transepidermal water loss rate decreased significantly compared with the baseline value; after continuous use for 7 days, the change rate of the subjects' transepidermal water loss rate compared with the baseline value was more than 7.8%, and the highest could reach 7.94%; after continuous use for 14 days, the change rate of the subjects' transepidermal water loss rate compared with the baseline value was more than 14%, and the highest could reach 15.10%.

After continuous use for 7 days, the change rate of the subjects' skin a values ​​compared with the baseline values ​​was more than 14%, and the highest could reach 14.98%; after continuous use for 14 days, the change rate of the subjects' skin a values ​​compared with the baseline values ​​was more than 15%, and the highest could reach 15.73%.

[0126] Comparative Example 1-2 changes the type of emulsifier stabilizer, which will affect the moisturizing and repairing effects of the product to a certain extent. After continuous use for 7 days and 14 days, the moisture content of the stratum corneum of the subjects, the transepidermal water loss rate of the skin, and the change rate of the skin a value are all reduced compared with Examples 1-3.

[0127] Comparative Example 3-4 changes the mass ratio of surfactant to emulsifier stabilizer, which is not within the scope of protection of this application and will also affect the moisturizing and repair effects of the product to a certain extent. After continuous use for 7 and 14 days, the moisture content of the stratum corneum of the subjects, the transepidermal water loss rate of the skin, and the change rate of the skin a value are all reduced compared with Examples 1-3, but higher than Comparative Example 1-2, which is the same as the conclusion of Table 1 above.

[0128] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions of the technical solution of the present invention by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the present invention.
