I make a number of MP goatsmilk soap, using Essential oils like sweetgrass, heather and green tea, all of which are mild single notes that blend well with goatsmilk.
Almond seems to be a good seller of mine as well. Anything with a vanilla in it will turn a tan color in time because as vanilla ages it turns darker. Ive been avoiding those as I want to not add too much additives to a natural thing.
