Conclusion
 More similar are the chemicals characteristics
of the new products (in terms of chain lenght
S content and Cl content), more similar results
are obtained on leather articles.
 The new chlorinated and sulpho-chlorinated
chemicals can be easily used to produce a
common fatliquoring agent.
 The new chlorinated and sulpho-chlorinated
chemicals didn’t request particular application
process and may be replaced instead of
chlorinated and sulpho-chlorinated paraffin to
produce very similar results.
