I know there are probably a lot of alternative names for formaldehyde used in products. Do you know or have a list of the other names?

Here are the ones I could find: 

Formalin 
Methanal 
Methyl aldehyde 
Methylene oxide 
Morbicid acid 
Oxymethylene 



And these preservatives, found in personal care products, release formaldehyde: Quaternium-15 
2-bromo-2nitropropane-1,3-diol imidazolidinyl urea 
diazolidinyl urea
