Abstract

The invention provides an active system and a preparation method thereof. The active system is prepared from the following raw materials in parts by weight: 3 to 6 parts of microalgae extracting solution, 1.32 to 6.26 parts of protective substance and 0.01 to 0.08 part of chitosan. According to the active system prepared through a formula and the method which are provided by the invention, on thebasis of increasing the original stability of the microalgae extracting solution, the favorable antioxidation function of the microalgae extracting solution is maintained.

Description

technical field [0001] The invention relates to the technical field of cosmetics, and more specifically, relates to an active system and a preparation method thereof. Background technique [0002] Cosmetics and daily necessities with natural ingredients are attracting more and more attention, and substances with natural ingredients also have good effects. The microalgae polysaccharide water extract is rich in active polysaccharides, which have a very broad application prospect in the field of skin care. Such substances can effectively protect skin tissue, resist oxidation, and scavenge free radicals. [0003] However, because there are many ingredients in natural extracts, the stability is not as good as that of chemical substances with a single ingredient, so it will affect the quality of cosmetics and daily necessities in the later stage. For example, terpenoids, flavonoids, tannins, and phenols in natural extracts are charged and easily adsorbed to each other or to other...
