  Dimethyl oxazolidine preservative? Calling Dr. Phil.

  Posted by chemicalmatt on January 28, 2022 at 4:12 pm

  Has anyone used dimethyl oxazolidine (CAS# 51200-87-4) to preserve formulations and can they recommend it? @PhilGeis must know something about it. Can the good doctor or anybody else weigh in here? The lit from Troy - they supply it as TroyCare BDX1 - advises to use at pH6 and above, which would make it ideal for higher pH formulas where the organic acids are useless.

  Hey Matt! Introduced back in late 70’s by Angus, think it was  formaldehyde releaser “Oxiban A”. worked pretty well.  
  Germall et al. already had the role so never got a foothold in the market.  Recall only one product that used it back then - (don’t laugh) - Brylcreme.

  Brylcreme!  “A little dab’ll do ya!” Thanks, Phil.
