Hi all I make Magnesium Oil (not for selling) and only make 120 ml at a time for personal use. It is basically Magnesium Chloride Flakes and Distilled water. I have been adding 1% PlantaservE Preservative (Phenoxyethanol 90%, Ethylhexylglycerin 10%). I havent had any issues and use within a month or 2.
Is this preservative adequate in your opinion - Do I need ETDA chelator etc or anything else? I also dont measure the pH for this product. I also sometimes add MSM Powder about 10% (Methyl Sulphonyl Methane or Dimethyl Sulfone).
The method I use is purely heating the Mag Chloride (and MSM if using) and Water until the Mag flakes (and MSM if using) dissolve (only probably to around 50 degrees C) and then once cooled to around 40 degrees C I add the preservative. It is then poured in a sterile bottle and I keep at around 25 degrees (ie the temp in my house). Many thanks for any opinions. Cheers Squinny
