Description

Technical Field

[0001] The invention relates to the technical field of cosmetics, and in particular to a skin care product containing a purple corn extract and a preparation method thereof. Background Art

[0002] With the rapid development of science and technology and the improvement of people's living standards, more and more people are beginning to pay attention to skin care issues.

[0003] Skin aging is a common oxidation phenomenon, which is usually reflected in skin elasticity, skin wrinkles and roughness, moisturizing intensity and other aspects. In the current cosmetics field, most cosmetic raw materials are chemical reagents, which have great side effects on the skin and human body, while natural plant nutrient skin care products are safer. Proanthocyanidins (PC) are a general term for a large class of polyphenol compounds widely found in plants. They have strong antioxidant and free radical scavenging effects and are powerful metal chelators. They can chelate metal ions to form inert compounds in the body; protect and stabilize vitamin C, and help the absorption and utilization of vitamin C. Therefore, how to improve its adaptability in cosmetics is particularly important. Summary of the invention

[0012] Furthermore, the filler is distilled water.

[0013] The present invention also provides a method for preparing a skin care product containing purple corn extract, comprising the following steps:

[0014] Put purple corn extract, ginkgo branch extract and sucrose in distilled water and stir with a glass rod until they are completely dissolved into a first aqueous phase;

[0015] The solubilizer and the moisturizer are magnetically stirred at a first temperature to fully dissolve the solubilizer into an oil phase, and the first water phase and the oil phase are magnetically stirred in a first preset ratio to form a main emulsion;

[0016] The whey protein isolate is subjected to magnetic stirring in distilled water at a second temperature to denature the protein, and konjac glucomannan is added thereto for stirring and gelling to obtain a second aqueous phase;

[0017] The second aqueous phase is blended with the main emulsion according to a second preset ratio, and a conditioner and auxiliary materials are added to gel to obtain the skin care product containing the purple corn extract.
