Separation type: Liquid Chromatography HILIC
High Performance Liquid Chromatography (HPLC) Method of Imidazolidinyl urea.
Imidazolidinyl urea is used in cosmetics as a preservative due to its antimicrobial properties. It is active against a broad spectrum of gram positive and gram negative bacteria, yeast and molds. It can be retained in HPLC using a SHARC 1 column, which uses hydrogen-bonding as a separation mechanism. The isocratic method uses a mobile phase of acetonitrile (ACN) and water. Imidazolidinyl urea can be monitored by low UV (210 nm), ELSD, CAD or LC/MS.

Application Column
SHARC 1
The SHARC™ family of innovative columns represents the first commercially available columns primarily utilizing separation based on hydrogen bonding. SHARC stands for Specific Hydrogen-bond Adsorption Resolution Column. Hydrogen bonding involves an interaction or attraction between a bound hydrogen atom and molecules containing electronegative atoms, such as oxygen, nitrogen, and fluorine.
