Plasticizer is a synthetic chemical, which is a polymer material additive widely used in industry. Adding this substance in plastic processing can enhance its flexibility and make it easy to process. Due to its characteristics, it is often added to hair dye and cosmetics as a softener and stabilizer, which can make the product more smooth after applying and increase the viscosity of the product, make the product more stable and greatly extend the shelf life. According to data, plasticizers will cause harm to the reproductive system, immune system, and digestive system of the human body, such as impairing male reproductive ability, promoting precocious puberty in women, and may cause gender confusion in children. Long-term large-scale intake can also lead to liver cancer. The European Union and the United States have listed plasticizer as priority control pollutants. Therefore, for safety reasons, the detection of plasticizer in cosmetics is an essential step in the production and sales of their products.
Phthalate esters, aliphatic dibasic acid esters, phosphate esters, polyol esters, benzene polyacid esters, citric acid esters, polyesters, epoxies, chlorides and reactive plasticizer.
There are different pretreatment methods and analysis methods for plasticizer detection in different substrates such as cosmetics. The sample pretreatment methods involved in the detection of plasticizers mainly include liquid-liquid extraction, solid phase extraction, solid phase microextraction, supercritical flow extraction, microwave dissolution, column chromatography, etc. The analysis methods involved in the detection of plasticizer mainly include spectrophotometry, fluorescence spectrophotometry, gas chromatography, liquid chromatography, gas chromatography-mass spectrometry, liquid mass spectrometry, etc.
CD Formulation has more than ten years of experience in cosmetic testing, and has mastered a large number of plasticizer testing technologies, especially high performance liquid chromatography, gas chromatography, gas chromatography-mass spectrometry and liquid- mass spectrometry technology research, which can accurately evaluate the qualitative and quantitative evaluation of cosmetic plasticizer. In addition, due to the complexity of the cosmetics matrix, it is difficult to pretreat the samples during the test, our expert team has developed a special sample pretreatment method for milk and cream cosmetics with complex matrix, which solves the problem of matrix interference during sample testing and makes the test results more accurate. At the same time , our expert team can carry out method specificity, linearity, detection limit, precision, recovery rate, stability and other methods according to the interference problems of different sample pretreatment conditions, different sample matrices, and different quantitative methods. The scientific verification test is carried out to test the actual plasticizer samples for cosmetics.
