Chelating agents with Glyceryl Stearate; is EDTA Failing Emulsions?
I’m starting to work with ceteareth-25 and glyceryl stearate as my emulsifiers, added to the cetearyl alcohol. I’ve read, so is it true, that EDTA’s are not compatible with glyceryl stearate? I’m using the standard glyceryl stearate, not the SE, or Citrate versions. Every lotion that I have made with disodium EDTA and these two emulsifiers has separated within 1 day. And, two lotions that I made without the Disodium EDTA has not separated yet, and it’s been 3 days?
If this is true, can anyone suggest some compatible chelating agents?
My body lotion ingredients:
Water Phase: Water, Glycerin, Hydroxyethylcellulose (HEC), Disodium EDTA
Oil Phase: Caprylic/Capric, Cetyl Alcohol, Shea Butter, Stearic Acid, Cetearyl Alcohol, Ceteareth-25, Glyceryl Stearate
Cooling Stage: Fragrance, Phenoxyethanol, Benzyl Alcohol, Ethylhexylglycerin
Thanks for your help.
