I know that Calcium Chloride is a fire suppressant, and since Calcium Stearate is also a calcium salt, does it have a similar effect? If so, it's going to be a pain to remove, since it is also a crystal.

You are on the wrong forum. There are friendly folks who might give you some casual advise here, and maybe a couple here (who aren't talking) with actual expertise. It looks like you established an account here just to talk about sugar rocket propellant. No big a priori deal with that. But when you have to ask "...is calcium stearate like calcium chloride because they are both calcium salts?" I'm calling out "BS". I think you are too uneducated to be cook book mixing up propellants in your garage and trying to load it into cases. You're going to blow yourself up. At the very least your going to get the stuff all over your clothes. Wear gloves and an apron. Sheesh.

And stay the hec away from zinc/sulfur micrograin.
