At Cromogenia Units, we continue to drive solutions that combine technical performance with true sustainability. We know that in some processes, sulphones remain irreplaceable; that’s why, instead of giving up their effectiveness, we decided to reinvent them.
Why RETANAL XDW?
We present RETANAL XDW, a new generation of sulphones with low bisphenol content, designed to deliver the same retanning efficiency with a cleaner chemistry. Its technical behaviour is identical to that of a conventional sulphone, maintaining tanning power, whiteness, softness and fastness, but with a safer composition aligned with current environmental standards.
Better Chemistry. Same Process.
RETANAL XDW can be used in all types of leathers — from wet white to semi-vegetable articles — without the need to modify process conditions.
An innovation that reaffirms our commitment: high-performance products with a reduced environmental impact.
