Description

Technical Field

[0001] The invention relates to the technical field of preparation of skin care compositions, and in particular to a facial skin care composition based on simulating native vernix caseosa of infants and a preparation method thereof. Background Art

[0002] At present, with the improvement of the awareness of infant and child skin care, the skin care demand scenarios have become more and more detailed, and "adapting to the times" has become the skin care principle of consumers. Emergency scenarios and seasonal scenarios are the main scenarios with high discussion among consumers. In autumn and winter, the temperature is low, the air humidity is low, and the sebum secretion is low, which can easily lead to dry skin, flaking and redness. For example, the single product of face cream is difficult to absorb when using the face cream, and the residual feeling after absorption is strong, the experience is very poor, and there is more oil remaining on the skin surface, which may also cause the skin's air permeability to deteriorate, leading to dermatitis and allergies. In addition, the skin is easily damaged by external factors such as dryness and cold in autumn and winter, and it is necessary to use a face cream with moisturizing and repairing functions to nourish and soothe the skin. If the ingredients of the face cream have poor repair ability, the damaged problem cannot be effectively improved. Usually, a large amount of moisturizers and soothing repair agents need to be added to improve the above phenomenon. Traditional creams on the market use a large amount of mineral oils to ensure the moisturizing performance of the product, but they are slowly absorbed and have a strong residual feeling when used, and the use experience is poor. At the same time, too much oil remains on the skin surface, which will cause other problems on the skin. Moreover, it is becoming more and more important to improve the efficiency of the preparation and operation of skin care compositions.

[0003] Chinese Patent Publication No. CN: 110974767 A discloses a composition for skin barrier regeneration and repair and its application, the composition comprising the following components in parts by weight: 1-2 parts by weight of hydrogenated lecithin, 1-3 parts by weight of phytosterols, 2-4 parts by weight of olive-derived squalane, 1.5-3 parts by weight of C8-12 acid triglycerides, 1-3 parts by weight of waste malt meal wax, 1-4 parts by weight of avocado tree fat extract, 0.3-0.8 parts by weight of argania spinosa kernel oil, 0.1-1 parts by weight of hyaluronic acid, and 0.2-1.5 parts by weight of vitamin E; the above composition does not contain ceramide which is usually added as a separate component, and the invention does not involve the problem of improving the efficiency of the preparation and operation of the skin care composition.

[0012] Furthermore, when the analysis and verification module of the present invention preliminarily determines that the preparation and operation of the skin care composition meets the standards based on the acquired leveling, it secondarily determines whether the preparation and operation of the skin care composition meets the standards based on the acquired color; and, when it is determined that the preparation and operation of the skin care composition does not meet the standards, it determines the reason why the preparation and operation of the skin care composition does not meet the standards based on the difference between the acquired leveling and the preset leveling benchmark.

[0013] Furthermore, when the analysis and verification module of the present invention secondarily determines that the preparation and operation of the skin care composition does not meet the standards based on the difference between the acquired chromaticity and the preset chromaticity benchmark, it determines the reason why the preparation and operation of the skin care composition does not meet the standards based on the difference between the acquired leveling and the preset leveling benchmark, and the reasons include leveling benchmark problems and skin care composition raw material problems.

[0014] Furthermore, when the analysis and verification module of the present invention determines that the reason why the preparation and operation of the skin care composition does not meet the standards is a problem with the leveling benchmark based on the difference between the obtained leveling and the preset leveling benchmark, the leveling benchmark is redetermined based on the obtained color. And, when it is determined that the reason why the preparation and operation of the skin care composition does not meet the standards is a problem with the raw materials of the skin care composition, the raw material addition amount or the raw material emulsification temperature value is redetermined based on the obtained leveling.

[0015] Furthermore, the analysis and verification module of the present invention is provided with a plurality of correction methods for the leveling benchmark based on the difference between the acquired hue and the preset hue benchmark, and the correction range of each correction method for the leveling benchmark is different.

[0016] Furthermore, when the analysis and verification module of the present invention determines that the reason why the preparation and operation of the skin care composition does not meet the standards is a problem with the raw materials of the skin care composition, based on the difference between the obtained leveling degree and the preset leveling degree benchmark, when it is determined that the raw material problem is a problem with the raw material emulsifier, the amount of emulsifier added is redetermined, or, when it is determined that the raw material problem of the skin care composition is a problem with the raw material emulsification temperature, the emulsification temperature range is redetermined based on the type of emulsifier and according to the raw material instructions.

[0017] Furthermore, the present invention provides a plurality of adjustment methods for the amount of emulsifier added based on the difference between the obtained leveling degree and the preset leveling degree reference, and each adjustment method has a different addition range for the emulsifier.

[0018] Furthermore, in the step S5 of the present invention, the composition is heated at 80° C. and stirred continuously while being kept at 80° C., the oil phase is added to the water phase and then homogenized for 5 minutes and then stirred and cooled to obtain a facial skin care composition.

The present invention can quickly determine whether the preparation and operation of the skin care composition meets the standards through the acquired leveling, thereby improving the efficiency of the preparation and operation of the skin care composition. The color obtained can be used to determine whether the operation of the skin care composition meets the standards for the second time, thereby improving the accuracy of the preparation and operation of the skin care composition. The reason why the operation of the skin care composition does not meet the standards is determined by the difference between the acquired leveling and the preset leveling benchmark, which saves time in finding the cause and improves the efficiency of the preparation and operation of the skin care composition.
