Sodium EDTA
SKU: 1ZX08440
Sodium EDTA is used as a chelating agent to help remove metal contamination especially iron from perfume, perfume compounds, aroma chemicals and essential oils. Long term storage in steel drums can lead to a metalic note developing and for some materials discolouration. The Sodium EDTA is added at 1% by weight to the material and being water soluble should precipitate. After 7 days the clear oil can be decanted off. Also often add to finished perfumes in hydro-alcohol solution at 0.1% to chelate iron that may have been come from stirring equipment and tanks during manufacture or may even be in traces in the essential oils used. Free iron (Fe) in a compound can act as an "Oxygen magnet" causing degradation and discolouration.

Application Suitability
Important Notes:
End application data applies to experiments carried out by the authors or extrapolated from those experiments using computer algorithms. As application product formulations vary widely this information is only a general guide.
Full testing by both perfumers- flavorists and end users is the only proven method to ensuring a perfume or flavours safety- strength- suitability- stability and success.
Legislation and regulations vary widely and change with time so it is your duty to check this.
