Determination of mineral oil and white petrolatum ratios in ointment products by capillary gas chromatography
- Calgon Vestal Laboratories, St. Louis, MO (United States)
The determination of mineral oil and white petrolatum ratios in ointment products is important due to regulatory and formulation concerns. A capillary gas chromatographic method utilizing on-column temperature programmed injection and flame ionization detection has been developed to characterize mineral oil and white petrolatum raw materials. Once the raw materials have been characterized, the method can then be used to estimate the ratios of mineral oil and white petrolatum in the ointment product. Chromatographic method development work along with the final chromatographic conditions will be presented. Chromatograms of raw material and final formulation sample analyses demonstrate the utility of the method.
