Abstract: 
We present a unifying approach to deformations of an associative algebra A that allows to derive known formulas of Moyal-Vey (1949) and Coll-Gerstenhaber-Giaquinto (1989) from a more general point of view. Such universal deformation formulas correspond to special deformations of the comultiplication of a bialgebra.
