I have checked Google and have seen conflicting answers to how to properly add and Essential Oil as an Active Ingredient to a Lotion.
Some say to first dilute the Essential Oil in a Carrier oil and then add it to the lotion.
Others say to add the oil directly to the lotion.
I am trying to put 3% Marigold Essential Oil into my lotion - not as a fragrance but as an Active Ingredient.
Does anyone know if there is an accepted guideline or the proper way to calculate the 3%? Do you dilute first or do you not before adding it to the lotion?
In addition some say to heat and mix others say just to mix the oils in.
