Have you made topicals yet? Or are you just getting started?
There are different methods and materials all done about the same way with the same result.
By not decarbing cannabis in topicals you get the thca with anti-inflammatory properties.
I use unprocessed coconut oil but other oils will work depending on how you want it to turn out. Olive oil is greasier but tastes better. Avocado oil tastes good, is good for your skin and infuses well with cannabis.
I use a crock pot on low or warm...It should never boil, don't cover (if you have to cover, use a paper towel under the lid so condensation won't get in the oil).
Cannabis must be fully submerged in the oil. I don't measure, I eyeball it. Cook for a couple of hours...depending on color and smell. If it smells like it's roasting, get it off the heat.
Let it cool before you strain it!
What you strain it with depends on how large a batch you do and how small your cannabis material is. Cheese cloth, unbleached coffee filters, pantyhose, bubble bags. I use a ricer and a permanent coffee filter as my final straining.
Then set up a double boil or water bath system. I use a Mason jar lid under the measuring cup.
For topicals, I add cocoa butter but other butters like shea work too.
And bees wax. Use a spoon or drop test to tell how much.
Beeswax melts at 140 F to 150 F (60 C to 65 C)
Set the container of oil in a cool, dry place. Let it cool completely to a solid. Don't rush it, the more oil you have the longer it will take.
Then I use a regular hand mixer to whip it into a rub.
This is the time you can add Magnesium Chloride oil.
