Problems solved by technology

However, due to the high cost of natural pigment extraction and unstable color, it is easy to be affected by various factors (such as light, temperature, oxidation, pH value, medium polarity, metal ions, additives, etc.) Changes in discoloration and other aspects affect its coloring effect, which seriously restricts the process of replacing artificial pigments with natural pigments, so ...

Abstract

The invention discloses a preparation method for a moisturizing lipstick containing shikonin liposomes. The formula comprises 9-11% of shikonin liposomes, 48-52% of component A, 25-28% of oil-based component B, 6-9% of water, 0.5-1% of polysaccharide and 4-6% of emulsifiers. The preparation method comprises the steps that (1) the shikonin liposomes are prepared; (2) the component A is prepared, specifically, the component A is selected from a waxy component and/or an oil-based component A; (3) the component A and the shikonin liposomes are heated and mixed in proportion to obtain a mixture A;(4) the oil-based component B is prepared; (5) an aqueous moisturizer is prepared, specifically, the aqueous moisturizer is a mixture of the water and the polysaccharide; (6) the emulsifiers are prepared; (7) the oil-based component B and the aqueous moisturizer are slowly stirred and mixed, the emulsifiers are added and stirred uniformly, a stabilizing emulsion is obtained, and the temperature ismaintained at 75-85 DEG C to obtain a mixture B; (8) the mixture A and the mixture B are mixed and stirred uniformly; and (9) the mixture obtained in the step (8) is subjected to injection molding at75-85 DEG C and cooled to room temperature for demoulding to obtain a product.

Description

(1) Technical field [0001] The invention belongs to the field of cosmetics, and in particular relates to a method for making moisturizing lipstick. (2) Technical background [0002] Lipstick is a kind of lip cosmetic widely used by women every day. It can make lips rosy and shiny, moisturize, protect lips, increase facial beauty and correct lip contour. It is one of the essential beauty cosmetics for women. [0003] The colorant in lipstick is a substance that gives lips a bright lip color. Traditional lipsticks generally use artificial pigments as colorants to add to lipsticks. However, these synthetic pigments have certain toxicity, which originates from the arsenic, lead, copper, phenol, aniline, ether, chloride and sulfate in the synthetic pigments, which can cause different degrees of harm to the human body. Ingestion also has the possibility of teratogenicity and carcinogenicity, which may cause certain damage to the body of consumers who use lipstick for a long time....
