Method
- Place PG in a heat proof glass container. Add the HQ. Cover in plastic wrap leaving a steam vent. Heat to 170-185 set in a pot of water or a dbl boiler & stir to ensure even melting of the HQ.
- AT THE SAME TIME, Heat the Eucerin in a separate container (covered in plastic & with a steam vent) set in a pot or dbl boiler to the same temp. The container holding the Eucerin must be large enough to hold the PG/HQ mixture as well.
- Carefully add the hot HQ/PG mixture to the hot Eucerin, stirring it in as you pour. Blend thoroughly.
- Remove from heat & set aside to cool. Once it is warm but not hot, pour into yr pump bottle.
