Embodiment 1

[0034] Sample source: cosmetics market,

[0035] 1. Enrichment of chloramphenicol: take 4 grams of sample, place it in a separatory funnel, add 50 ml of ether, shake for 5 minutes, let stand for 5 minutes, separate the supernatant-ether soluble matter, and After drying at room temperature, the preparation section (a), namely the enrichment of chloramphenicol, is obtained.

[0036] 2. Enrichment of 1,2-propanediol: add 50-80 milliliters of ether to the above remaining lower layer to wash, discard the washing solution, place in an oven at 150 for 4 hours, and after cooling, the prepared Section (b), ie the enrichment of 1,2-propanediol.

[0037] 3. Chloramphenicol analysis:

[0038] A. High-performance liquid chromatography analysis: the instrument used is Shimadzu LC-3A high-performance liquid chromatography; the detector is UVD-2 ultraviolet detector; chromatographic column: Zorbax-ODS, 0.46 × 25cm; column temperature: 17 ° C; Mobile phase is methanol / water=85 / 15 (V%), 1.0m...

Abstract

An analytical method for chloromycetin and 1,2-dihydroxypropane in the medicine- skin care products comprising, performing enrichment for the chloromycetin and 1,2-dihydroxypropane, conducting qualitative analysis to the halomycetin rich didymium using highly effective liquid phase color spectrum, elementary analysis, mass spectrometric analysis, infrared spectrum analysis, and inorganic metallicion determination, then conducting qualitative analysis to the 1,2-dihydroxypropane rich didymium using highly effective liquid phase color spectrum, infrared spectrum analysis, and inorganic metallic ion determination, last using color spectrum outer marking method to accomplish the quantitative analysis of the halomycetin and 1,2-dihydroxypropane. The invention solves the problem of concentration enrichment for the unknown compositions, and can be used widely.

Description

[0001] Field: [0002] The invention belongs to a method for analyzing chloramphenicol and 1,2-propanediol, and in particular mainly relates to a qualitative and quantitative analysis method for chloramphenicol or 1,2-propanediol in medicine-skin care lotion Background technique: [0003] In modern life, facial care and beauty have become a fashion in life. Taking the consumption of cosmetics as statistics, the consumption of France, the United States, and Japan ranks in the forefront of the world; with the rapid development of my country's economy, the demand is also increasing. sharp growth trend. A wide variety of cosmetics flood the market. Because the beauty care of the face is often inseparable from the treatment of acne, inflammation, and mites, the comprehensive medicinal liquid that integrates beauty and medical care --- medicine-skin care liquid has become an important content in the cosmetics market. The tremendous increase in demand for facial care has also raised...
