I love 6006, and usually use LX wicks with it. I agree the FO completely changes the burn characteristics, so may need to wick up or down depending. Some FO' s are heavy.
ICs pink sugar is one of my favorites! As far as cosmetic scents I’m not sure because I used mine in candles. My favs were baked apples, classic cinnamon buns. I have tried others and all the ICS oils were strong.
I love ICS baked apples, it was a scent from Snowtop years ago, they had great scents.
A plain apple that I tried and loved wax Candlewics red apple peel.
I love sultry angel from CC. I like the vanilla voodoo, but it is not may favorite vanilla. All of her oils are great, very complex and recommended usage is like half what you would normally use.
I used MC fresh cut grass and it was nice. Another one I had one time was Breezy Meadow, but I can't remember what company carried that one.Maybe AH/RE. Its been awhile since I made that scent.
