I like making small quantities often, to avoid preservatives which can irritate my "patient's" skin, but this cream has too many ingredients to make that practical -- the solution is to make this in two steps. First, mix the oils and waxes, then make the cream (i.e. add water) with only a portion of the oils. I can store the leftover oil mix in the refrigerator, where it will last a very long time (bacteria and mold need water to grow), then I can make extra cream quickly whenever I need it.

Step 1: Equipment
You will need two wide mouth jars or similar containers: one for the finished cream and one for storing the extra oil/wax blend. Containers should be able to hold at least 1/2 cup each.
A recycled honey bottle or a similar container which can stand on its cap will work for the finished cream but not for the oil blend which will harden, especially if you store it in the refrigerator.
If you have a small precise scale (one which can weigh up to 1/10th of a gram is best, but if it only goes to 1 gram that's OK too) making this cream is a lot easier and faster -- but I give measurements in volume as well as grams, so you can measure either way.
