By the way, I found the box. Same artwork. Doesn't have "Ceda Serica" anywhere on it.
I did find a Candlewic SDS for Ceda Serica. Link
Of the Ceda Serica pictures I found, the majority show the wax in slab form with the same pattern on the bottoms. Every case I received from Candlewic was in shrink wrapped rectangular blocks. I know Candlewic has the equipment and facility to melt and pour their own slabs/blocks (there's an old video somewhere on the net showing them doing it), so I wonder if they repackage it and pass it off as theirs, which is pretty common these days. This post, claiming to have contacted Calwax, supports that thought.
Incidentally, for those who don't think Ceda Serica has paraffin in it, that Candlewic SDS lists "paraffin fume" as a decomposition product.
Noticed that the SDS is published on the new coconut apricot product page. It clearly states "revision" and replaces "paraffin fume" with "wax fumes". The inclusion of "saturated mineral hydrocarbons" makes me wonder if they're MOSH, which would mean it could contain mineral oil.
