Science & Benefits

Tropolone is a high-purity organic compound that functions as a powerful antioxidant and chelating agent. In 2026 formulations, it is primarily used to 'boost' preservative systems (like Phenoxyethanol), allowing for lower concentrations of preservatives overall. It is 100% non-comedogenic. For acne patients, it helps prevent the degradation of active ingredients in the bottle, ensuring that your BHA or Retinol remains at full potency until the last drop.
