        Blankophor DML  is the product name, chemical family 
     Bistriazinylaminostilbene (thank God, I am not a Chemist) a C.I. 
     Fluorescent Brightener 71. Information  is off MSDS.
        I understand it is used in detergents like you said. A white 
     powder, weak odor, shows up under UV light. Not recommended for 
     prolong skin contact,avoid eye contact, users should wash hands and 
     face before eating, drinking and using tobacco products (shouldn't we 
     all). Senior Health Physic Tech here said it worked well in training 
     years back. However, can't remember where the small quantity we had 
     came from. Information I have on MSDS is a company called MOBAY CORP. 
     Dyes,Pigments and Organics Division, Mobay Road, Pittsburgh, PA 
     15205-9741. However, they may have produced and supplied in bulk 
     amounts only.
        This probably was not much help, wish you luck in you quest!

Does anybody know where I can get some of the fluorescent powder that is 
used as "simulated" contamination during training.  I think you put a uv 
light on it and it shows up.  Are there common compounds that can be used 
for this purpose (I seem to remember certain laundy detergents) or do I have 
to buy some high-dollar "official" stuff??
     
Thanks for your help in advance.
