I have this scent, too. I have been dragging my heels about soaping it because I have not had good results with anything 'Ginger." After a family vacation to Hawaii, I decided to make Hawaiin themed soaps, and I tried a bunch of gingery ones from different companies. None of them smelled at all like ginger and some smelled awful. The worst was a ginger-lime one...not from BB. Please review yours if you soap it...otherwise, I might just ditch mine.
It can be a multitude of reasons. The weather, the temp of the FO when added to the mixture.(I'm kidding about the weather but who knows) I noticed that if I warm them up they give me less trouble. Sometimes it can be the mixture of oils. The only thing that will tell is if you try with a small batch. I work fast so sometimes I do not even know if it is troublesome. FO's are the very last thing I add, just to be on the safe side
