Sodium Benzoate

Also known as benzoate of soda
MODERATE

A common preservative that stops mould and bacteria in acidic drinks and sauces.

What it is

The sodium salt of benzoic acid, used to preserve fizzy drinks, fruit juices, pickles and dressings.

Health concern

Safe at approved levels, but when combined with vitamin C (ascorbic acid) it can form trace benzene, a carcinogen. Some studies link benzoate + artificial colours to hyperactivity in children.

The verdict

Generally low-risk, but watch for it alongside vitamin C and artificial dyes in kids' drinks.
