  Non-ionic water phase stabilizer for emulsion suggestions

  Posted by Abdullah on December 13, 2020 at 10:35 am

  Can you suggest some non-ionic or cationic water phase stabilizer for emulsion as i have cationic preservative Ethyl Lauroyl Arginate HCl which is not compatible with anionic xanthan gum or carbomer.

  Emulsifiers are Polyglyceryl 4 Laurate and glyceryl oleate.

  @Abdullah  perhaps try a modified nonionic cellulosic such as hydroxyethyl cellulose, hydroxyproyl methylcellulose, or methylcellulose.

  @chemicalmatt 
  As you suggested i tried HEC, HPMC and guar gum. At different quantities from %0.1 up to %0.5, alone and blended with each other but they were not stable. Creaming happens after some days. 

  Any other suggestions

  Here is the formula 

  Olive oil %6
  Petrolatum %4
  Glycerin %3
  Essential oil %0.4
  Ethyl Lauroyl Arginate HCl %0.2
  Glyceryl Caprylate %1
  Polyglyceryl 4 Laurate %1-3
  Glyceryl oleate %1-3
  Required HLB 7.26
