To start you want a very clean Thermomix so that there is no contamination. I wash my Thermomix bowl with 100ml of vinegar and 500ml of water and heat on Varoma, 5mins, Sp 4.
Fill your Thermoserver with hot water to heat briefly. Tip out before use.
Place the filtered water and glycerin in the TM bowl. Heat to 70'/2 minutes/Sp 3
Pour into empty Thermoserver to keep warm.
Add oil phase ingredients to TM bowl making sure the wax pellets aren't sitting on the blades (or they won't melt). Heat to 70' 2 minutes, Sp 3.
Insert butterfly and place lid on top with MC inverted. Start your Thermomix at 5mins/70'/Sp 4. Slowly pour the water phase onto the top of the lid. When you are adding the water, add it slowly to start with and then you can speed it up, just like a mayonnaise. You want it all to mix for another couple of minutes after you have incorporated all of the water.
When it is finished it is very runny, nothing like a cream. Don't fear! Pour it into your sterilised containers and let it set with the lid off. Make sure you wash your bowl, lid, MC and butterfly in hot soapy water immediately. When I make moisturiser I actually pop these all (minus the blades) in the dishwasher.
It is best to keep your cream away from sunlight and only use clean hands to dip into it. If not using straight away, keep refrigerated.
Notes and Variations
You can add some essential oils into the oil phase if you like but I don't. I add mine after. I often make a batch, or a double batch, pour and let it set. Then I doctor up each little jar to suit the end purpose or recipient. For example, I make several small jars for my children simply to use as a carrier for their essential oil blends. I have one for sleeping, one for mosquito bites, one for studying etc. They each have a little first aid kit in their bedrooms. Then I make up a cream for my husband, it is scented with more masculine oils. Into my own I love to add some of the more nourishing oils like rosehip and camellia with some essential oils like lavender, orange and rosemary.
