Lotion is an emulsion of water-based and oil-based ingredients so it will accept either addition, depending on how much you plan to add. Adding too many "extra" ingredients can break the emulsion and cause it to separate. The extracts you mention could be either water or oil based, depending on your source. You also need to be careful about adding things to a lotion that could grow bacteria. If you are unsure, it is always best to keep it refrigerated and use it within a week or two. Good luck!
Thank you very much! im only planing on making weekly batches so hopeful it will keep thinks from growing ^^
