Potassium Citrate
A pH helper that keeps a product’s acidity steady and binds trace metals.
What it does
It keeps a product’s pH steady and binds trace metals that can spoil a product. It’s there to keep the product stable, not to do anything to your skin.
The evidence, graded
expert consensusUS safety reviewers (2014) assessed citric acid, 12 citrate salts and 20 citrate esters, and judged them safe as used. The report lists potassium citrate as a pH adjuster, a buffer that holds pH steady, and a chelating agent, which binds metals. It’s generally recognized as safe to add to food, so the review looked mainly at skin exposure.Fiume 2014 · International Journal of Toxicology ↗
