Proud to have been the first stockist of this wonderful new RM
 
Supplied at 1% or 10% in DPG:
This stuff is so strong that it's very likely that this is all you will ever need. 
Tropicalia is used in traces, and at the very most about 1-2% of a formula. 
At high doses, it can be unpleasant, a bit like overrripe bins or decomposing fruit. 
IFF are of course selling it for the purposes of anyone from laundry conditioner to huge volume candle applications - but that leads some to think that its price and pack sizes mean that one should stock up on 10g neat. IMO even 10g neat would be a bit of a liability (have fun diluting) and about 5x more than a life time supply for most hobbyists.
