Determination of Formaldehyde-releasing Preservative Imidazolidinyl Urea in Cosmetics

RU Ge;CHEN Dan-dan;YUAN Xiao-qian;ZHENG Rong;Shanghai Institute for Food and Drug Control;  
A method for the determination of imidazolidinyl urea in cosmetics was established. By determining the content of formaldehyde released from imidazolidinyl urea, the content of imidazolidinyl urea was determined indirectly. Imidazolidinyl urea degraded rapidly and released formaldehyde under alkaline condition. After reacting with 2,4-dinitrophenylhydrazine and separated by Intersil ODS-SP, formaldehyde was determined at 355 nm. The results showed that under the experimental conditions, imidazolidinyl urea could degrade to stable concentration. The detection limit of this method was 0.001%, and the recovery rates varied from 92.1% to 109.5%. The method which ?lled the blanks of Safety and Technical Standards for Cosmetics can be used to determine the content of imidazolidinyl urea in cosmetics and to rule the use of formaldehyde-releasing preservatives.
