In recent past I have tried numerous ''natural'' preservation system ranging from Geogard 221, Biopein, Neopein, Suorapein (from BioBotanica), grapefruit seed extract, Leucidal, Silverion etc. I never had any accomplishment with these as phenoxyethanol proved to be superior to any of before mentioned supstances.
Has anyone tried Geogard Ultra?
What do you think about natural preservatives? Is there any that can reliably be used for vast application and are they really worth the trouble and extra money, mostly?
Have you had any success with using any, if so, can you describe it? What do you think is the future of using preservatives in cosmetics, as this topic tend to be mentioned more and more?
