A lot of fruit seeds like raspberry I've noticed effect the scent. Some things that may not so much are poppy seeds, ground almonds, hemp seed, pumice, gound olive pits. Also jojoba beads. I haven't used the jojoba beads in any of my applications but I've seen them in other people's srubs. They come in different colors which I think is pretty cool. I also like to use ground vanilla bean. MMS has them. It will add a touch of vanilla scent but the one I have isn't very strong. I think they would go well with any vanilla blended scrubs.
