Problems solved by technology

There are few reports on effective heterodoping methods for CQDs. Due to the high solubility of the inorganic precursors of dopants, the conventional hydrothermal carbonization route will result in a large amount of dopants remaining in the reaction solution, so the synthesized CQDs N- low doping

Abstract

The invention belongs to the field of beauty and hairdressing, and discloses a green and environment-friendly hair styling finishing agent, a preparation method and an application. The hair styling finishing agent is made from the following raw materials in parts by mass: 3-6 parts of citric acid, 1-3 parts of chlorophyll a, 0.1-0.8 parts of mercaptoethylamine and 0.01-0.1 parts of sodium selenite. The preparation follows the following steps: respectively dissolve citric acid and chlorophyll a in pure water, add mercaptoethylamine and sodium selenite after mixing, and dissolve to obtain a mixed solution; move the mixed solution to a polytetrafluoroethylene lining, and place the inner Put the liner into a stainless steel reaction kettle, put it in an oven, and conduct a hydrothermal reaction at 140-200°C for 120-240 minutes; take out the solution when the temperature of the oven drops to room temperature, and centrifuge it at 4000-10000r / min for 10-30 minutes. The clear liquid was dialyzed with a 200 Da dialysis bag for 2 to 4 days, and then freeze-dried to obtain a green environmental protection hair styling agent.

Description

technical field [0001] The invention belongs to the field of beauty and hairdressing, and in particular relates to a green and environment-friendly hair styling finishing agent, its preparation method and application. Background technique [0002] In order to explore whether heteroatom-doped carbon quantum dots CQDs have antibacterial activity and the relationship between antibacterial activity and the surface structure of CQDs, Travlou et al. used poly(4-styrene sodium sulfonate) or polyvinylpyrrolidone as sulfur or nitrogen sources, respectively. , S-CQDs and N-CQDs were synthesized by hydrothermal method, and the killing ability of the two CQDs on Bacillus subtilis and Escherichia coli was explored by qualitative disk diffusion method and MIC quantitative test. It was found that compared with S-CQD, N-CQD had higher bactericidal activity, the antibacterial activity of N-CQD was mainly related to its positive surface charge, and the antibacterial activity of S-CQD was main...
