Results on singular products of Schwartz distributions on
the Euclidean space are derived when the products are so
'balanced' that they exist in the distribution space. The results
follow the idea of a known distributional product published by Jan
Mikusiński and are obtained in Colombeau algebra of
generalized functions. This algebra contains the distributions and the notion
of 'association' permits obtaining results on the level of distributions.
