PHENYLMERCURIC ACETATE Chemical compatibility with O-rings, rubbers, & plastics

Phenylmercuric acetate (PMA) is an organomercury compound used primarily as a preservative in eye drops and paints. It is a white crystalline solid with antifungal and antibacterial properties. PMA acts as a disinfectant by releasing mercury ions, which inhibit microbial growth. Due to its toxicity and potential health hazards, its use has been significantly reduced or banned in many applications. It is highly toxic to humans and the environment, causing neurological and renal damage upon exposure. Handling PMA requires strict safety measures, including protective clothing and proper ventilation. Disposal of PMA must comply with hazardous waste regulations to prevent environmental contamination. Alternatives to PMA are being explored to reduce the reliance on mercury-based preservatives. Its usage is now limited to specific, controlled applications where effective and safe substitutes are not available.
