Mixing essential/fragrance oils with propylene glycol
Would it be a disaster to mix my E.O. or F.O.s with propylene glycol when I’m weighing my ingredients to make lotion INSTEAD of adding the P.G. to the heated water phase?
This combining would be done just before I start making the lotion, so it’s not a permanent mixture that might sit weeks or months before being used (in case that would be a problem).I normally use 5% P.G. in my lotions.I thought of doing this as a way of decreasing the amount of E.O. or F.O. that I lose because of it sticking to the container I weigh it in. This way, if it’s diluted in P.G., I’ll leave a smaller quantity of the E.O. or F.O. on the weighing container’s sides.I have not included a formula because I thought I’d do this with ALL the lotions, unless it’s a dumbass idea.Thanks ahead of time for advice/comments/ -

if your formulas are already stable using your “old” method I don’t see enough reason to jeopardize stability by changing the production procedure.
If you are for some reason worried about the loss of your EO/FO you could dissolve only the remaining part (the part sticking to the container) in a bit of propyleneglycol or better - if there is alcohol in the formula - some ethanol.in case your formulas are still in the development phase - it is worth testing - that is what development is all about! -
It seems a fine enough idea to me.Of course, you could also weigh the bottle that contains your EO and pour it directly into the batch rather than using a weighing container. To do this you would have to have a good idea of how much pouring is equivalent to the amount you want in your batch.
