I don't know of any published reference. Namely: The category of commutative algebras is enriched over the cartesian closed category of commutative coalgebras. Does anybody know of a published reference ? (I am in a posoition of a 1981 M.Sc. thesis by Ernst K. Pedersen, giving the details of the constructions involved.)
