Preparation method of after-sun repair emulsion containing discolored red alga extracts

Abstract

The invention provides a preparation method of an after-sun repair emulsion containing discolored red alga extracts, and belongs to the technical field of emulsion preparation. The preparation methodcomprises the steps of preparation of the discolored red alga extracts, preparation of raw materials by weight part, preparation of aqueous phase liquid, emulsification, cooling and the like. The redalga extracts contain a lot of ultraviolet resistant active substances, the ultraviolet resistance is high, and a very good chemical sunscreen effect is achieved. Licorice roots and flores chamomillaehave the functions of clearing away heat and toxic materials, fighting against bacteria, diminishing inflammation and calming the nerves, so that the after-sun repair emulsion is suitable for variousskins and especially for the sensitive skin, and the after-sun repair emulsion can be used for repairing the skin which is burnt by the sun. In the preparation method, nanometer supercritical propolis is adopted, the nanometer supercritical propolis is very easily permeated and absorbed, the problem about the compatibility with other components is successfully solved, and the nanometer supercritical propolis has effects of high oxidation resistance and inhibition of tyrosinase activity, and has remarkable effects of whitening and freckle removal.

Description

technical field [0001] The invention relates to the technical field of emulsion preparation, in particular to a method for preparing an after-sun repair emulsion containing decolorized red algae extract. Background technique [0002] Emulsion is the most basic step in skin care. Effective ingredients such as moisturizing, whitening, and anti-aging in the emulsion can be better absorbed by the skin. It is very important to have a good bottle of emulsion. Many emulsions on the market today contain a lot of chemicals Synthetic, long-term use will have certain side effects on the skin, making it difficult for the nutrients in the emulsion to be absorbed, and even cause adverse reactions such as skin inflammation. If it is not selected properly, it will cause immeasurable losses. , there is a big problem in the selection and dosage of chemical substances, the natural ingredients are less, and the skin care effect is not good, which needs further improvement.
