Is a liner required with Baby bee botty butter?

[LittleGem]

I'm hoping someone with a bit more experience with cloth will be able to help me. I've just gotten some baby bee botty butter, but I'm not sure if I will need to use a liner with it? It doesn't contain zinc, but I'm not sure if the beeswax also clogs up nappies, does anyone know?

Ingredients are - various oils, beeswax, cocoa butter and siam benzoin resin.

Thanks
