Coca-Cola has announced it is removing a controversial flavouring stabiliser from some of its drinks following concerns that an element of the ingredient is also found in flame retardants.
There has been some concern over the fact BVO contains bromide, which is also found in brominated flame retardants.
The use of BVO as a food additive is currently not allowed in the European Union or Japan.
In the US, drinks companies can use it at up to 15 parts per million.
Research by the Mayo Clinic claims excessive consumption of drinks containing BVO can lead to negative health effects, such as memory loss and skin problems.
Coca-Cola, which maintains its use of BVO was safe for consumers, will replace it with sucrose acetate isobutyrate or glycerol ester of rosin.
The campaign against the use of BVO was started by a teenager from Mississippi.
Sarah Kavanagh circulated a series of petitions calling on Coca-Cola and Pepsi to remove the ingredient.
"I knew that if Gatorade could do the right thing, so could Powerade," she said.
"I'm glad to know the Powerade sold at my school and consumed by people around the world will be a little bit healthier without BVO in it."
