  Crystals in Myristyl Myristate

  Posted by jiroband on May 24, 2016 at 4:21 pm

  I have some old Myristyl Myristate (approx. 7 years old). I just opened it and discovered small clear crystals throughout that look like coarse salt. What are these crystals, and is this safe to use?

  Thanks!

  Myristyl Myristate -> Myristol acid + Myristol alcohol -> Myristol aldehyde + Myristol alcohol

  Thanks, Belassi.

  Is it still usable, or has it “decomposed”?

  Probably you are viewing the results of a decomposition reaction of some kind. I would bin it. If it has reached the final phase, I suspect there would be a smell, because aldehydes usually are quite smelly.

  I strongly suspect it’s contamination of some kind

  myristyl myristate is not reactive enough to undergo susbtantial hydrolysis or reduction in air, even over seven years

  Why not check the melt point before you trash it?
