Analysis of creams
- 77 Downloads
A standardtlc procedure was tested for its applicability in the qualitative analysis of several creams. It was found that in creams of known composition the presence of almost all of the active cream components as well as the excipients can be confirmed. An additional eluent, spray reagent, or a liquid extraction clean-up step sometimes appeared to be necessary. If the cream base composition is not known, a ‘fingerprint’ of the various types of excipients is obtained with the described procedure.
