Is formalin or DMDM hydantoin compatible with ammonium lauryl sulfate?

In book cosmetic Microbiology it said formalin is incompatible with ammonium and iron.

My questions are. 
1. Is formalin compatible with ammonium lauryl sulfate?

2. If no then what about formaldehyde releasers like DMDM hydantoin completely with ammonium lauryl sulfate?
