are alchemical items considered magic?

So, may already have been answered but I can't find official clarification.

Are alchemical items considered magical?

This would mean you could detect them with detect magic and that you could only craft 1/day. I understood but need clarification, that alchemical items are not magical but imitate a magic effect with less chance of success (lower dc's)

Can someone clarify or provide a link clarifying this conundrum?

No, they're alchemical not magical.

There's no 1/day limit (actually there's feats to craft a LOT in a day)
