Expert Verdict
Potassium biphthalate is prohibited in the EU due to phthalate-related regulatory concerns, though chemically distinct from restricted phthalate esters. The phthalate association creates significant regulatory and marketing risk; EU REACH and consumer advocacy groups increasingly scrutinize all phthalate-related substances. Potential metabolic hydrolysis to phthalic acid raises theoretical concern. Not recommended for consumer-facing formulations without robust safety dossier justification. Consider alternative buffers such as citrate or lactate systems.
