Desogen and Dimanin

From: Pierlucio Pellissier <ppellissier>
Date: Friday, May 17, 2002
Could someone direct me to a supplier of Desogen (Ciba-Geigy) or
Dimanin (Bayer), possibly in Canada or N.A.

As you well know both are quaternary ammonium salts used in the AB
57 solution to clean and disinfect mural paintings.

Ciba-Geigy (now Novartis) seems to be unaware of the product they
used to produce and  Bayer doesn't answer my e-mails.

Are you aware of a possible equivalent substitute?
