Quality Assurance Of The Ointments - Gako Unguator e/s Operating Instructions Manual

4.4 Quality Assurance of the Ointments

Simple test methods convincingly demonstrate the good homogenizing capability of
®
the UNGUATOR Mixing System. The test is performed using analog formulations
with colored powders such as iron oxide (red/hydrophilic, yellow/hydrophobic) or Su-
dan red and riboflavin [2] or methylene blue [4]. Here the examination of ointment
streaks from various levels of the mixing jar using a magnifying glass or microscope
have demonstrated the success of the mixing process, as has viewing one or more
®
sections of an "ointment block" that can be pressed out of the UNGUATOR Jar as a
whole after it was placed into a freezer overnight. "Mixing up" such analog formulations
®
not only ensures that UNGUATOR Mixing System is being used correctly: it also allows
®
our customers to build up trust in the modern UNGUATOR Technology and the quality
associated with it.
