The Truth About Preservatives Including Grapefruit Seed Extract and Parabens

“Grapefruit Seed Extract (GSE) is an all natural preservative”
There are rumors all over the web that Grapefruit Seed Extract works as a natural preservative. Oh, we wish these were true. We even considered using it in our products. However, the sad truth is GSE is not an all natural preservative. GSE is no more natural than parabens. Grapefruit seed extract is
not grapefruit juice. It is
not simply ground up grapefruit seeds. It is
not grapefruit essential oil.
Chemical manufacturers take the leftover grapefruit pulp, a waste by-product from grapefruit juice production, and in an intensive, multi-step industrial chemical process, change the natural phenolic compounds into synthetic quaternary ammonium compounds (does this sound natural to you?). Typically, in chemical synthesis of this type, chemical reagents and catalysts are used under extreme high heat and pressure or vacuum. Synthetic ammonium chloride is one of the chemical catalysts used in this process.
So, first all, Grapefruit Seed Extract is not “natural”. It’s a chemically altered form of grapefruit seed. If you’re going to call it Grapefruit Seed Extract, you could by the same reasoning call Sodium Laurel Sulfate Coconut Oil Extract.
Secondly, studies done on GSE have found that while it may be mildly preserving, it appears to be due to trace contaminants, rather than the GSE itself.
A handmade Grapefruit Seed Extract that was not tainted with other chemicals showed zero preservative qualities. Here is one report from the Institute of Pharmacy, Ernst Moritz Arndt University, Greifswald, Germany:..."

Все другие косметические компании, обсуждаемые в этой теме, делают то же самое
🙂 И, само собой, на своих сайтах хвалят тольуо свою продукцию.
