What research says

How it’s made and used

  • Preservative mold inhibition2

    In lab studies, methyl p-hydroxybenzoate stopped mold growth better than sodium benzoate and potassium sorbate, except in one mold.

The signal at the top counts the findings in people and in animal and lab studies. A concern in studies of people outranks animal and lab studies, and “No concerns” needs at least two findings in people. Findings whose study type is not stated are shown but not counted.
