  Is formalin or DMDM hydantoin compatible with ammonium lauryl sulfate?

  Posted by Abdullah on December 23, 2021 at 7:30 am

  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?

  FA releasers have been used in shampoos with this ingredient for decades.

  @PhilGeis thanks 

  What about formalin? 

  The pH of product would be acidic.

  This is from the book

  Is it true ammonium system is harder to preserve than sodium due to extra nitrogen source?
