The Coca-Cola Company has agreed to stop using an ingredient known as B.V.O by the end of the year.
Turns out a chemical in brominated vegetable oil is also used as a flame retardant.
A Mississippi teenager led the charge through a petition on change.org.
After 200,000 people signed it, Pepsi agreed to remove B.V.O from Gatorade.
Now, Coca-Cola is following suit.
B.V.O is used in citrus-flavored drinks, keeping the ingredients from separating from each other.
