What is ceresin?

I've used Jake's Purple Ceresin lube for about 4=5 years now and, while I'd be happy to try other lubes, I can't find any reason to. I did try out their moly lube, but went back to the Purple and have stuck with it ever since. What I like about it is that it stays put better than the others I tried previously. I got very frustrated with products containing beeswax and/or carnauba, with the lube ending up all over everything, basically. I run my lubrisizer at about 120-124F depending on the temperature in the garage, and at that temperature it flows quite nicely. WHen the bullet comes out, the lube is pretty much there to stay. There is still some buildup in the seating die over time, but far less than other stuff I initially used.

It was actually White Label's Carnauba Red that sent me looking for something else. I'm sure it's a wonderful lube but I just couldn't seem to get a handle on...handling it. I think I ended up with as much on the outside of finished ammo as I did in the grease grooves. Just not for me. I think if I lubed 100 bullets then loaded them immediately things might have gone better.
