Imidazolidinyl urea came to the attention as the result of a class study on formaldehyde releasers. Used in combination with parabens, imidazolidinyl urea is one of the most widely used preservative systems in the world and is commonly found in cosmetics. Since a prolonged exposure may cause allergic reaction in some individuals, it is important to control the formulation of your product and its compliance with the law limits, in order to testify its quality and trustworthiness.
Chelab Laboratories has set up a rapid and sensible HPLC/MS analytical method, enabling the determination of the content of Imidazolidinyl Urea (IMU) in cosmetic products, reaching a limit of detection of 0,05 g/100 g of product tested. The test uses the reversed phase chromatography with mobile phases containing a suitable mixture of buffer and acetonitrile, fluxed at low flux on different polarity columns linked in series.
The analysis is performed in creams and foundations.
The results are available in 7 business days.
