Yes, I had to adjust the ph by adding Sodium Hydroxide as my lotion was on the acidic side. Do you have a personal preference over Optiphen Plus versus Geogard ECT? I’ve been using Geogard ECT in my lotions and facial cleansers and haven’t run into any issues. I have read that Optiphen Plus is a good broad spectrum preservative but can’t find as much information on Geogard ECT.

Thank you Bobzchemist. I’ll have to check if I can obtain this ingredient from a Canadian supplier as I don’t recognize based on the suppliers I currently use in Canada. Do you have another suggestion or equivalent ingredient that would be easily sourced?

Thank you again for responding, I appreciate your help.
