Application Notes

Cyromazine is triazine based molecule that is used as an insect growth inhibitor for the protection of livestock and poultry houses. Standard values have been set for its use in veterinary drugs, and a notification method using HPLC has been issued. In this study, extraction and purification were performed with a mixed-mode polymer SPE (InertSep MCX FF) using a method based on the notification test method from the Ministry of Health, Labor and Welfare and literature examples*, and analysis was performed using HPLC (detection at UV 240nm) and LC-MS/MS.

In this note, it is shown the analysis of UV absorbers in cosmetic products.<br />UV absorbers contained in cosmetic products are compounds that prevent the skin from being penetrated and burned by UV rays by absorbing the energy of UV rays and converting it into thermal energy.<br />The compounds are analyzed below. They are used in several products commonly available in the market with sunscreen formulation such as cosmetics, hair care products, and perfumes.<br />In this note, 8 compounds of UV absorbers were analyzed by gradient elution. The results show an excellent separation of the compounds.
