Geogard Ultra is a naturally-derived, broad spectrum preservative. It utilizes "hurdle technology" to protect formulations from contamination and is widely considered a reliable and safe alternative to traditional preservatives.
The two primary components of this preservative are Gluconolactone and Sodium Benzoate.
This preservative offers many reassurances as to its safety. Laboratory tests show that Geogard improves skin moisture content, has an excellent toxicity profile as well as a long history of use, is non-sensitizing and non-irritating. It is listed as GRAS (Generally Recognized As Safe) ingredient, has a broad compatibility with other widely used cosmetic ingredients, contains no GMO's, and is developed without using animal testing.
However, there are also some concerns about Geogard Ultra. When Sodium Benzoate, the primary ingredient in Geogard Ultra, is combined with ascorbic acid (vitamin C) they create a chemical known as Benzene. This occurs due to the decarboxylation of benzoic acid when in the presence of ascorbic acid. This happens most consistently when these two components are exposed to heat and light. Benzene is carcinogenic. Additionally, Benzene fed to mice causes mitochondrial degeneration - one of the primary causes of aging and cell death. It is important to note that both components, (heat & light) must be present for this change to occur. Sodium Benzoate on its own is considered non-carcinogenic.
- Globally accepted (as opposed to the many cosmetic products made in America)
Deciding which preservative system is most in line with your personal needs and priorities should be done with caution and diligent research. For those comfortable with the data concerning Sodium Benzoate, Geogard Ultra is an excellent alternative to harsher, more toxic preservatives.
