The pesticide residues in the raw materials of cosmetics will have a variety of side effects on human body, which can affect reproductive development and even cause cancer.
CD Formulation can provide pesticide residue detection services, complete the accurate qualitative and quantitative determination of various pesticides in cosmetics containing plant extracts, and provide effective basis for the safety of cosmetics.
With the development of social economy and the improvement of people's living standard, green and functional cosmetics are more and more favored by people. Plants have a long history as the main source of makeup and basic raw materials, but environmental pollution makes it inevitable that there are pesticide residues in plant extracts.
At present, the main methods for the determination of pesticide residues in cosmetics include high performance liquid chromatography, liquid chromatography-tandem mass spectrometry, gas chromatography-mass spectrometry and gas chromatography-tandem mass spectrometry. There are many kinds of pesticide residues, and the matrix of cosmetics containing plant extracts is complex, so the sample pretreatment process is complicated.
CD Formulation provides these detectors, which can test the sample efficiently and quickly, helping customers get the content of pesticide residues in cosmetics. The detailed procedure is as follows.
1) Prepare the standard reserve solution and dilute the diluted solution into a solution of different concentrations to obtain a mixed standard working curve solution;
2) Weighing samples, make sample solutions after proper front processing;
3) Use the instrument to detect the standard working curve solution and sample solution;
4) Draw the standard curve. By the comparison of the retention time and the standard curve, the pesticide residues in cosmetics are performed qualitatively and quantitatively.
