Hey all! First post:
Anyone see any glaring gaps of broad spectrum coverage in this preservative combination? As long as I keep the pH at or below 5 and use GMP? Any percentages I should bump up?
.2% Sodium Dehydroacetate + .2% Potassium Sorbate + .5% Glucono delta lactone + 1% Caprylyl Glycol/Glyceryl Laurate/Glyceryl Undecylenate (Jeecide Cap-7) + .2% edta
Also any foreseeable issues of compatibility with anionic, non-ionic, cationic or emulsion systems that I missed?
Last thought - is EDTA necessary as a chelator with the glucono delta lactone already included?
