What Is Disodium Pyrroloquinolinedione Tricarboxylate?
Disodium Pyrroloquinolinedione Tricarboxylate is a lab made salt form of pyrroloquinoline quinone, a small molecule best known for its strong ability to fight oxidation. Scientists first isolated the parent compound from certain bacteria in the late 1970s while studying natural growth factors. Skin care chemists later converted it to this water soluble disodium version so it could blend smoothly into creams and serums. Production starts with fermented glucose that yields pyrroloquinoline quinone, which then reacts with sodium salts to gain better stability and an easier texture for topical use.

Common formats include lightweight day creams, antioxidant booster serums, leave-on masks, after-sun gels and eye treatments. Brands add it when they want a high performance yet gentle antioxidant that feels comfortable on all skin types.
