  best antioxidants to help slow cosmetic formulations discoloring

  Posted by nullafulla on September 9, 2019 at 6:05 am

  Hi,

  Wondering if you guys have any suggestions for water-soluble ingredients that will help slow a formulation from oxidizing to extend product life.

  I’ve heard sodium metabisulfite might be a good option, I’ve never worked with it, any feedback/tips for those that have? Being a sulfite, I’m assuming could be a skin irritant but not tested myself?

  Also, thinking Propyl gallate, although again never worked with it. Would love to hear your suggestions.

  
  

  Thanks

  It depends on what specific ingredient do you want to prevent from oxidizing.
  Sometimes it ain’t real oxidation, just chemical degradation trough other pathways.
