Consumer Advice
Sodium propyl p-hydroxybenzoate is the sodium salt of propyl p-hydroxybenzoate; in China it is one of the few parabens still permitted under GB 2760, limited to specific foods such as soy sauce, vinegar and carbonated drinks with strict maximum levels. The EU no longer authorises any paraben for food. At permitted levels it is generally safe, although allergic reactions are possible in very rare cases. Choosing products from reputable brands is sufficient.
