Body Spray, matching Lotion, M & P Soaps in special molds, Lip Balm, Rose Petal Soaps hmmm Wax Dipped or Injected Bear Air Fresheners (I guess that's not B&B though), Sorry, that's all I can think of right now.
Are you affixing your wick to the jar and after pouring are you using something to hold the wick in place until the wax has set up? I use wick bars or two sticks.
I wouldn't go over an ounce for soaps. In Lotions I only add by drops. What percentage are you using? If you want the FO to linger on the skin, I'd layer by using a soap, and body lotion and maybe a spray in the same FO.
If you do a search on here, I'm sure you will find the answer. There is a wealth of information here and most every question you could ask has probably been answered many times over. You have to be careful how much FO you use, you don't want to cause problems with burning on the skin. I know if you put too much FO in soap you will get burning.... and in places that you don't want to burn , ask me how I know! Also B&B Suppliers usually have recipes on their sites. Do your research and testing BEFORE you give out products to friends and family or sell!
