Is there any additive needed besides propylene glycol for formulation of a product containing essential oil as the main pharmacological component? Is that suitable and safe?
You may directly add essential oil and mixed it. But this is for additive purpose in feed either in liquid diet or in solid diet. Please go through the dose of essential oil.
Thank you. I want to know which additives are usually needed for making a simple natural formulation containing essential oil (edible). For example is propylene glycol enough or other ingredients are needed?
The first question of relevance is, whether you look for an oral formulation, or a topical formulation..and for what indication you wish to develop. This question needs a context!
