General guidelines for the UNGUATOR
®
Mixing System
The “scratching and grinding check” on the ball of one’s thumb familiar from traditional
preparation methods is often enough. Pasting should be repeated depending on the
results of inspection.
Pregrinding has the advantage that ingredients are distributed fairly evenly along the
UNGUATOR
®
Jar wall, and homogenize quickly with the remaining formulation
constituents added, even in large UNGUATOR
®
Jars.
After the pre-ground ingredients have been pasted, the remaining foundation and all
other remaining formulation constituents can be weighed in.
2.2.5 Suspension > 2%
Mixing semisolid substances with a portion of microfine, agglomerated, optionally fine-
grained solid substances of more than 2 %.
Examples:
Zincum oxydatum, acidum salicylicum, urea in aqueous foundation
We recommend using the UNGUATOR
®
SMB.
The preparation of a pre-ground substance is can be skipped for suspensions with
more than 2 % content of active ingredients in favor of mixing time extension. First of
all, the foundation should be rendered on weighing-in. Then the liquid constituents
should be weighed in. Finally, the solid constituents are filled into the UNGUATOR
®
Jar.
In so doing, ensure that these are placed into recesses and covered with foundation
ointment. This will avoid direct contact with the UNGUATOR
® MB and achieve better
homogeneity.
2.2.6 Gel
Mixing gel.
Example:
Hydroxypropyl cellulose 400
We recommend using the UNGUATOR ® Disp. Blade for up to 200 ml.
Gel preparations are mixed, with several intervals, at high speed during the required
swell time thus preventing agglomerations and slightly reducing soaking time. Principle-
related, trapped air will normally clear after the preparation is allowed to settle for a
while.
