Sorry, this is is so late, but in my experience Kokum has very little odor. I've bought it many times because I almost alway use it in creams/lotions (except in facial ones), in different countries, and it has never smelled very strongly of anything. At this point if it did I would suspect I got a bad batch, I think.
Regarding the melt point, I've never had issues with difficulty applying it when used in lotion bars or lip balms, I guess because the liquid oils drop the melt point. But it has been a really long time since I have lived in a cold place. I don't know if things would be different if I were trying to use them at less than 50 or 60F. It seems like in my experiments with lip balms (it's been years, I might be mis-remembering), I sometimes had some graininess, but I can't remember if I used a butter that was susceptible to that (eg,shea), or if might have been a harder butter coagulating.
