| Abstract: |
| The widespread use of cosmetic products at home and abroad makes its safety problem attract extensive attention．As the first choice to find out the safety problem of cosmetic samples，analysis and detection technology is very important．Various morphology and complex matrix which cosmetic samples are characterized by bring great challenges to the detection of target analytes in cosmetics．Traditional sample pretreatment methods cannot meet the requirements for green and efficient detection due to the disadvantages of large reagent and time consumption，tedious preparation steps，etc．Therefore，it is of great significance to promote the rapid development of new sample pretreatment methods．An overview on the sample pretreatment methods for cosmetic samples analysis in the past five years is provided in this paper．The sample pretreatment methods which are placed special emphasis on in this review are phase separation methods，mainly including solid phase extraction，solid phase microextraction and liquid phase microextraction，field assisted methods including ultrasound-assisted，microwave-assisted and vortex-assisted extraction，and derivatization methods including post-column and pre-column derivatization．These techniques are used in a vast range of modern extraction process，which are of increasing interest．Finally，the prospect of the development direction of sample pretreatments for cosmetics samples analysis are also put forward. |
