Combine the carrier oil, shea butter, coconut oil and cocoa butter in a microwaveable jug and heat for 30 seconds at a time in the microwave until the butters have completely melted. Stir in between each heat burst.
This process could also be done in a double boiler.
Place in the fridge for about 45 minutes, until the mixture is quite firm.
Remove from the fridge and add the essential oils, if using.
Add the colloidal oatmeal and stir through. You can use a mixer to whip it if you prefer. If you do whip it, the mixture will double in size, so allow for this when getting your glass jar ready.
Transfer the whipped body butter to the glass jar.
Keep the body butter in a cool, dry place and use as needed.
