Sodium benzoate
Approved and considered safe within set limits. Worth limiting in sugary soft drinks, especially combined with vitamin C, and for children sensitive to additives.
Citric acid
Safe. It’s the acid naturally found in lemons, usually made by fermentation. The only practical concern is tooth enamel in acidic drinks.
