One issue with aloe is the fact it cannot be oil. It is the gel inside the aloe which is basically a watery product. You will want to go a bit low with it in lotion. WSP has it in extract form, but it is water, glycerin, aloe juice, and citric acid. You could dissolve a little 100x aloe powder in your heat phase if you want aloe in your lotion. As for argan butter use argan oil and up you thicken a bit or use a thickening emulsifier such as Glyceryl Stearate (Gms-SE). Increasing Cetyl Alcohol, adding in a hard butter such as cocoa butter, kokum, illipe, etc. I do not like adding in bug food such into my lotions especially if you are new at lotion making lotion. Btw EDTA cannot be used with Glyceryl Stearate
If you are trying to make a lotion to take to a holiday market and not experienced at lotion making I would purchase a base from Essential by Catalina. They have some very luscious bases and make them in-house. Sadly they are out of their new pumpkin butter base but hopefully will run another soon.
