around the jar and the mixing process for larger jar sizes can be repeated.

Gel
With the mixing parameter “Gel” gelling agents can be incorporated into
fl
uids or semi-solid
foundation.
As an example, the preparation of ultrasonic contact gel, hydroxypropyl cellulose 400. Also
incorporation gelling agents like bentonite or Aerosil into a semi-solid foundation.
To ensure a homogenous distribution we recommend applying disp. blades for jar sizes up to
200 ml and the standard mixing blades for larger batches.
The
fl
uid component will be weighed out
fi
rst into the gako unguator Jar. Soluble active
substances can be administered directly into the jar and dissolved. The gelling agent will be
dispersed on top of the liquid component.
If the swelling agent will be incorporated into a semi-solid foundation, the gelling agent can be
covered between two foundation layers. This will obtain a faster dispersion of the gelling agent
into the foundation.
