Maybe I'm just going to the wrong forums, but nobody seems to be able to help me with my questions, so hopefully the bath/body people can help me out here? I'm looking to make fragrance roll-on's in 1/3 oz bottles. I have 4 questions: 1)Can I use the FO's from any supplier (daystar, MC, JbN) as long as they're deemed body safe? 2 )I'd like to use FCO since I don't like the greasiness of Jojoba oil. What percantage of FO do I need and what percentage of FCO do I need? 3) I would like to add a little bit of another carrier oil (with a long shelf-life) because of the dryness of the FCO, which would you recommend and what percent 'other oil' should I add to the FO/FCO mixture? (I was looking on oilsbynature.com, and there are so many oils listed...I don't mind an expensive oil since it will be for mine and family use only) 4) Can I use them right away or is there a curing time? Thanks for any answers, much appreciated!
