Description

Technical Field

[0001] The invention relates to the technical field of facial creams, and in particular to a highly moisturizing facial cream containing a liquid crystal emulsifier and a polymer thickener and a preparation method thereof. Background Art

[0002] With the development of economy and the improvement of people's living standards, consumers' demand for skin care products has gradually shifted from basic cleaning and moisturizing to the pursuit of more professional, efficient and safer skin care experience to meet their own care needs. If the skin is dehydrated for a long time, it will aggravate the loss of skin moisture, and cause problems such as roughness, dryness, tightness, flaking, redness and fine wrinkles. Especially for dry skin, choosing a suitable moisturizing cream can form a protective layer on the skin surface, which can better replenish moisture, keep the skin hydrated, and effectively relieve the above discomfort caused by skin dehydration.

[0003] Alkyl polyglycoside (APG) liquid crystal emulsifiers are a class of mild nonionic surfactants that can form a lamellar liquid crystal structure at the oil-water interface and can show good skin moisturizing properties. However, the stability of the emulsion prepared using APG liquid crystal emulsifiers alone is poor, and it is usually necessary to compound with other emulsifiers or add co-emulsifiers to improve its use effect. In addition, at low emulsifier dosages, the formula is very likely to undergo phase transition, resulting in an unstable emulsified system, which results in poor stability of the prepared cream and poor moisturizing and other effects. Summary of the invention

[0004] In view of this, the present invention provides a highly moisturizing facial cream containing a liquid crystal emulsifier and a polymer thickener and a preparation method thereof.

[0120] Phase E includes the following raw materials in parts by weight: 0.15 parts of dipotassium glycyrrhizinate.

[0121] The preparation method of the highly moisturizing facial cream containing a liquid crystal emulsifier and a polymer thickener comprises the following steps:

[0122] S1. Preparation of phase A: stir glycerol, sodium hyaluronate and carbomer to obtain a preformed liquid; add deionized water into a main pot, turn on the stirrer at a stirring speed of 35 Hz, then add the preformed liquid to mix, then add 1,2-pentanediol, 1,2-hexanediol, panthenol and betaine in sequence, heat to 75° C., stir and mix evenly to obtain phase A;

[0123] S2, preparation of phase B: add Montanov 202 emulsifier, Montanov 68MB emulsifier, behenyl alcohol, squalane, jojoba seed oil, avocado butter, and polydimethylsiloxane into an oil pan, heat to 75° C., stir and mix at a speed of 35 Hz to obtain phase B;

[0124] S3. Under the condition of high-speed shear stirring at a speed of 45 Hz, slowly draw phase B into phase A. After the extraction, maintain the vacuum and homogenize at a speed of 3000 r / min for 14 min, then continue high-speed shear stirring for 12 min, gradually cool to 45°C, add phase D raw materials and homogenize twice at a speed of 3500 r / min for 2 min, finally add phase E and homogenize three times at a speed of 3500 r / min for 3 min, and discharge the material to obtain a highly moisturizing facial cream containing liquid crystal emulsifier and polymer thickener.

[0125] The performance test was conducted on the highly moisturizing facial creams prepared according to the above Examples 1-4 and Comparative Examples 1-5, wherein the viscosity was measured using an IKAROTAVISC lo-vi Advanced viscometer at 19.3°C and a rotation speed of 10 rpm; and the pH was measured using a pH meter. Appearance: Direct observation. The test results are shown in Table 1 below.

[0126] Table 1 High Moisturizing Cream Performance Test

[0127]

[0128] The above results show that the high moisturizing cream prepared by using suitable thickeners, emulsifiers and co-emulsifiers in Examples 1-4 of the present invention under specific process conditions has a suitable viscosity, can form a uniform, stable and delicate emulsified cream, and has a good moisturizing and skin-moistening effect after use, and the skin feels non-greasy. Compared with Example 4, in Comparative Example 1, both phase C and phase E are added to phase A during the preparation of the cream, and then subsequent homogenization and emulsification are performed, resulting in too high a consistency of phase A feed liquid, which is not easy to homogenize, thus resulting in emulsification failure, and failure to form a uniform, delicate and stable cream emulsion. Compared with Example 4, Comparative Example 2 first adds phase C to phase B and phase E to phase A to prepare the corresponding mixed raw materials, and then performs subsequent homogenization and emulsification, resulting in a high consistency of phase A feed liquid, which is not easy to homogenize, and insufficient homogenization causes the later cooling process to be prone to phase inversion, and the material body viscosity is low, and a uniform, delicate and stable cream emulsion is also not formed. Compared with Example 4, in Comparative Example 3, the rose water raw material in phase D was added to phase B, phase C was added to phase B, and phase E was added to phase A, which also resulted in insufficient emulsification. Although the emulsification was successful, the viscosity of the material after emulsification was low and the skin felt sticky. Compared with Example 4, the raw material phase C of Comparative Example 4 did not contain Montanov 202 emulsifier and behenyl alcohol, and the raw material of Comparative Example 5 did not contain phase C Aristoflex Silk thickener, resulting in insufficient emulsification. The prepared cream could not form a uniform and delicate cream-like emulsion, and the emulsification failed.

[0129] According to QBT 1857-2013 "Moisturizing Cream", the high moisturizing cream prepared in Examples 1-4 of the present invention was tested for stability (cold resistance, heat resistance);

[0130] Cold resistance: The facial creams prepared in Examples 1-4 were placed at -8°C for 24 hours, then taken out and restored to room temperature to observe the results.

[0131] Heat resistance: The creams prepared in Examples 1-4 were placed at 40°C for 24 hours and then taken out and restored to room temperature for observation. The test results are shown in Table 2 below.

[0132] Table 2 High Moisturizing Cream Stability Test

[0133]

[0134]

[0135] The above results show that the highly moisturizing facial creams prepared in Examples 1-4 of the present invention have good stability.

[0136] The highly moisturizing facial cream of Example 4 of the present invention was placed at room temperature for 24 hours, and then the liquid crystal structure was observed and photographed under a polarizing microscope. The results are as follows: Figure 1 shown.

[0137] Depend on Figure 1 It can be seen that the cream has a good liquid crystal structure with uniform size, large number and complete structure. It can significantly enhance the hydration closure effect, has strong moisturizing and water-locking properties, and remains stable for a long time.

[0138] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
