  cellulose problem with phenoxyethanol

  Posted by ZsoltE on July 15, 2016 at 7:46 pm

  Hello, people!
  I use a cellulose derivate (i think is HydroxyEthyl Methyl Cellulose) for forming a water-based gel, but it is incompatible with phenoxyethanol when i add preservatives a very ugly precipitation is formed. (mecellose from samsung-cellulose, and euxyl pe 9010 ) 
  Any ideas why?

  it’s just how preservatives don’t work on your base. seems like phenoxyethanol isn’t working for your cellulose base. I would not use any preservative blend that contains phenoxyethanol.. have you tried symdiol 68?

  I read somewhere (sorry, can’t remember where) that cellulose derivatives inactivate phenoxyethanol. That probably has something to do with it.
