I have been doing some additional research on Sodium Benzoate in some Network Marketing products.  Here is an article that talks about how Coke phased out the controversial additive:

Soft drink giant Coca-Cola is phasing out a controversial additive that has been linked to hyperactivity and causing damage to DNA.

The chemical Sodium Benzoate, also known as E211, is used to stop fizzy drinks going mouldy.

But recent research has shown that the chemical can deactivate parts of DNA, the genetic code in the cells of living creatures.

Coca-Cola said it was withdrawing the additive from Diet Coke in response to consumer demand for more natural products.

The move will mean that by the end of the year no can will contain E211 – and it plans to remove it from its other products as soon as possible.

But the company said at present it had not found a satisfactory alternative to replace the additive in some soft drinks with a higher juice content including Fanta and Dr Pepper.

Other fizzy drinks made by rival companies, such as Irn-Bru, Pepsi Max and Lucozade will continue to contain the additive.

While the chemical occurs naturally in some fruits, such as prunes, apples and cranberries, it is used in much greater strengths by the soft drinks industry.
Peter Piper, a professor of molecular biology research at Sheffield University found that the additive could switch off vital parts of DNA that could be linked to cirrhosis of the liver and Parkinson’s disease.
