Emulsion (Solution ointment)
With the mixing parameters “Emulsion” liquid components can be incorporated into hydro-
philic foundations at room temperature.
As an example, the preparation of aqueous hydrophilic ointment, aqueous lanolin alcohol oint-
ment or eucerin c. aqua aa. 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.
First, weigh out the entire amount of required foundation ground-covering inside the jar.
Then add the required amount of liquid or solution by room temperature.
The jar bottom should be pushed up so far as possible to prevent incorporating air.
In some cases emulsifying refrigerated foundations can cause di
ffi
culties. In this case the
process of emulsi
fi
cation can be accelerated by adding the required liquid warmed.

With the mixing parameters “Emulsion

” liquid components can be incorporated into a melted
foundation and cooling down parameters.
As an example, the preparation containing emulsi
fi
c. aquosa, lannette or cera.
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 jar is heat resistant up to 85 °C / 185 °F and can be used in a hot-water bath or microwave.
The melting components can be melted directly in the jar.
If there is no water in the formulation, the components can be melted directly in the jar on a
hot-water bath. Formulation containing an aqueous phase can be melted in a hot-water bath
or the microwave, leave the regular nozzle open and set the microwave to a low power setting.
The temperature control with a thermometer should take place in short intervals to make sure
the compound is not overheating.
