Embodiment 1

[0034] The present embodiment pulverizes the pitaya peel, extracts and obtains the red pigment solution of the pitaya peel, comprising the following steps:

[0035] Get fresh white-fleshed pitaya, take its pericarp, rinse with water, remove the cyan skin of the pericarp, weigh, and prepare purified water with a material-liquid ratio of 1-2:5-10 (mass ratio); the pitaya pericarp Cut into small pieces of 2 to 3 cm long, put them into a tissue grinder, add a small amount of water for beating, then add the remaining purified water, and stir to mix. Place it on a magnetic stirrer, stir and extract at a temperature of 10-30°C for 30-60 minutes; filter with four or six layers of gauze, and take the filtrate. Centrifuge the filtrate at a speed of 6000r / min for 8min to 15min, take the supernatant, then centrifuge at a speed of 10000r / min for 8min to 15min, take the supernatant to obtain a red pigment extract, bottle it, and store it in a -20°C refrigerator for later use .

Abstract

The invention relates to the technical field of nano materials, in particular to a preparation method of a natural biomass carbon dots lipstick. The invention provides the preparation method of the natural biomass carbon dots lipstick, and the method includes the following steps: step 1. mixing and grinding a first humectant and pigment to obtain a first humectant containing pigment; step 2. mixing a second humectant and white beeswax and heating in a water bath to obtain a first mixture; step 3. adding the first mixture in the step 2 into the first humectant containing pigment, and continuously stirring until the mixture is uniformly mixed to obtain a second mixture; and step 4. adding an antioxidant into the second mixture obtained in the step 3, uniformly stirring, pouring into a mold, cooling, molding, and demolding to obtain the natural biomass carbon dots lipstick, wherein the pigment powder solution is a red pigment powder solution of pitaya peel with carbon dots. The invention provides the preparation method of the natural biomass carbon dots lipstick, which solves the technical problems that natural pigments in existing cosmetics are easy to degrade and fade, and application is limited.

Description

technical field [0001] The invention relates to the technical field of nanometer materials, in particular to a preparation method of natural biomass carbon quantum dot lipstick. Background technique [0002] Carbon quantum dots, also known as graphene / graphene oxide quantum dots and carbon dots, are a new type of fluorescent nanomaterial with a carbon-based skeleton structure, usually a class of quasi-spherical carbon nanometers with a diameter of less than 10nm. particles. Pigment is one of the important raw materials for the coloring of cosmetics. People's choice of cosmetics is usually determined by the senses of vision, taste, and touch among the five senses and six senses. Therefore, color, as the most intuitive feeling, affects people's perception of cosmetics. Therefore, the proper use of pigments also plays a very important role in the quality of cosmetics. Synthetic pigments are artificially synthesized pigments, which are produced by chemical synthesis. Its adva...
