In a most preferred embodiment, the humectant of the present invention is glycerin and 1, 3-butylene glycol, wherein the glycerin and 1, 3-butylene glycol are present in a mass ratio of 1: 1.
emulsifier
The emulsifier of the present invention is a compound capable of forming a stable emulsion from a mixture of two or more components insoluble in each other.
In a preferred embodiment, the emulsifier according to the invention is selected from one or more of glycerol monostearate, tween 80, span 80, hydrogenated lecithin.
In a most preferred embodiment, the emulsifier of the present invention is hydrogenated lecithin.
In experiments, the inventor of the application finds that the hydrogenated lecithin is selected as the main emulsifier, so that unique skin feel can be brought. The reason why it may exist is that lecithin is an important component of biological membranes, has excellent compatibility with the skin, is an indispensable substance for stratum corneum cells, and can help the skin to reestablish a natural moisture barrier. The hydrogenated lecithin selected by the invention is prepared by hydrogenating and saturating natural lecithin from soybean, the content of hydrogenated phosphatidylcholine is not less than 70%, the stability is high, and the smell is low. The hydrogenated lecithin can form a unique bionic lamellar structure of the phospholipid in the cream, and has good skin-attaching property and affinity. It forms a protective film on the stratum corneum, building a good moisture barrier. Meanwhile, the composite material can be used as a conveying carrier for substances inside and outside the membrane, and can improve the absorption of active substances.
Because the hydrogenated lecithin has selectivity when emulsifying the grease, and the emulsifying capacity to the silicone oil and the vegetable oil is general, the inulin lauryl carbamate of natural source is selected as the auxiliary emulsifying agent, the emulsifying capacity is superior, and the oil is not selective. The two emulsifiers are compounded for use, different types of grease can be selected, the skin feel of the product is enriched, and the stability of the cream product is improved. Due to the addition of inulin lauryl carbamate, emulsion droplets with smaller sizes can be obtained, the adhesion degree of the product is further increased, and the permeability of active substances is increased;
hydrogenated lecithin has poor solubility in water and is not suitable for long-term heating. The component A is a water phase, and the component B is an oil phase, and the temperature is required to be heated to 80-85 ℃, so that the component A cannot be dissolved in the water phase or the oil phase firstly. According to the invention, hydrogenated lecithin is dispersed in the polyhydric alcohol in advance and is put into the emulsion before emulsification, so that the situation of discoloration and odor change caused by long-time high-temperature heating can be avoided. Wherein, the alcohol phase is the compound of glycerol and dihydric alcohol, which is beneficial to dispersion, and when the proportion of the polyhydric alcohol and the hydrogenated lecithin is controlled to be (15-19): (1.2-1.87), the dispersion effect of the hydrogenated lecithin in the polyol is best.
Thickening agent
The thickening agent is also called gelling agent and is a substance capable of increasing the viscosity of latex and liquid. The thickening agent can increase the viscosity of the system, keep the system in a uniform and stable suspension state or an emulsion state, or form a gel.
In a preferred embodiment, the thickener of the present invention is selected from one or more of xanthan gum, carbomer, hydroxyethyl acrylate/sodium acryloyldimethyl taurate copolymer.
In a more preferred embodiment, the thickener of the present invention is a carbomer.

2. And (3) centrifugal test: the compositions prepared in examples 1 to 11 were centrifuged at 3000r/min for 30min to observe whether or not there was any delamination, and the results are shown in Table 1 below.
3. Testing the moisturizing and moistening effects: 180 out of 25 to 55 year old volunteers were randomly divided into 9 groups of 20 persons, and the moisturizing and skin-care creams prepared in example 1 and examples 4 to 11 were used, respectively.
The test method comprises the following steps: all volunteers performed face cleaning treatment before sleeping every night, and each person used the distributed moisturizing cream on the right face and did not use the moisturizing cream on the left face. The trial period is one month, and the trial result is counted on the 30 th day. Effectively expressed that the left face and the right face of a test person are obviously finer, whiter, smoother, less fine lines on the face, obviously fades color spots, and is more white and elastic than the face; null means no change in the texture of the skin of the subject; the results are shown in table 1 below, where the skin quality of the test subjects was generally improved but the effect was not significant, ranging between effective and ineffective.
TABLE 1
4. Skin moisture, roughness, smoothness test:
the test method comprises the following steps: randomly selecting 30 volunteers, respectively cleaning the inner sides of the arms of the volunteers, wiping to dry, then resting for 30 minutes at constant temperature (21.2 ℃) and constant humidity (51% humidity), then testing the base value for 0h, and respectively testing again 3h and 6h after sample application. The water content of the skin of the volunteers after the skin cream is applied for 0h, 3h and 6h and the water content of the skin cream is not applied by using a corneometer 825, and the roughness and the smoothness of the skin of the volunteers after the skin cream is applied for 0h, 3h and 6h and the roughness and the smoothness of the skin cream are not applied by using VC 20plus, wherein the test average values are shown in the following tables 2 and 3.
5. The skin care cream prepared in example 1 was applied to the part of the hand in the tiger's mouth, and the immediate effect thereof is shown in fig. 3. FIG. 2 is a diagram showing the effect of skin cream not applied to the first web.
TABLE 2 stratum corneum moisture content (a.u)
| Time of day | 0h | 3h | 6h |
| Blank space | 28.27 | 34.31 | 34.43 |

| Blank space | 1.74 | 1.69 | 2.08 |
| Face cream | 2.43 | 9.44 | 8.5 |
According to the test, after the face cream is used by the volunteer, the moisture content of the skin of the volunteer is increased, the roughness is also improved, and the effect is better as the using time is longer. Fig. 1 is a photographic image of the effect of the applied skin cream and the unapplied skin cream in different time periods by adopting visiospav 20, and it can be known from the photographic image that after the skin cream is applied, the moisturizing effect is better, and the dry lines are effectively reduced. As can be seen from the comparison between FIG. 2 and FIG. 3, the cream has improved dry and crumbly skin, and has a very good moistening effect.
