Waxes, Hydrophilic ointment, etc.
Either pour warm water alone (≤ 85 °C/185 °F) or the heated remaining ingredients
constituents over Cera, Lanette N, etc. in the UNGUATOR® Jar,
or
pour water in the substances and heat them either in a heated-water bath (≤ 85 °C/185
°F) or carefully observed in a microwave oven. Formulations without water containing
components may be melted already directly inside the UNGUATOR® Jar by placing the jar
in the water bath.
Please note that the UNGUATOR® MB must not go in a microwave oven. Furthermore,
isolated areas of heat concentration may develop when heating in a microwave. To avoid
this, we recommend coarsely blending the content of the jar during heating using a spatula
at intervals. Please also keep in mind that a microwave will only heat aqueous substances.
Generally it is sufficient to homogenize heated mixtures in three cooling intervals of six
minutes each and apply 10 strokes each using the UNGUATOR® at high speed.
Homogenization of solid substances takes slightly longer. The cooling time and hence
the cooling interval can be shortened in the refrigerator or by using a water jacket. The
UNGUATOR® MB should remain in the UNGUATOR® Jar during the cooling phase.
For emulsions, it makes sense in some cases to pregrind ingredients using the whole fatty
phase and a low portion of water by a pregrinding. The remaining water can then be
filled in the UNGUATOR® Jar in additional steps when the mixing process is interrupted.
The advantage of pregrinding, where the basic ingredients are mixed evenly along the
UNGUATOR® Jar wall, is a relatively fast bonding of the liquid constituents. This in turn
assures an increased tightness of the sealing lips, even for large UNGUATOR® Jars and
extended mixing processes.
4.6 After the mixing process is complete
The UNGUATOR® Mixing System is released and removed from the UNGUATOR® oscillation
arm once the mixing process is finished. Unscrew the UNGUATOR® Jar Lid from the
oscillation arm and/or twist the UNGUATOR® MB shaft counterclockwise. This will only
require a quarter turn, which may already have happened when releasing the jar from the
oscillation arm. For this reason, we recommend holding the UNGUATOR ® Mixing System
tightly with one hand when removing it from the UNGUATOR®.
In the next step, the UNGUATOR® Jar Lid is opened and the UNGUATOR® MB removed.
Since this is also an opportunity execute a quality check, the UNGUATOR® Jar Lid should
also be opened after mixing when using the UNGUATOR® Disp. Blade. Practice has proved
that if the surface of the ointment looks smooth and if the minimum defined mixing time
