I made an emulsion with Heliosoft/Siligel. The pH is 5.25-5.5.
I have always used Germall Plus in my emulsions, so they have been 99.5% natural. I love Germall Plus, it's solid!
If I were to replace Germall with a natural broad spectrum preservative, what are some options that people have gotten good results with?
My Contract Manufacturer is suggesting Linatural MBS-1 ( (Propanediol, Ethylhexylglycerin, Potassium Sorbate) or Troycare FE01(Iodopropynyl Butylcarbamate and Phenoxyethanol).
I have heard not so good things about Linatural, and I am not familiar with Troycare.
What are your thoughts/suggestions based on your experience?
Thank you so much!
