Higher Grade, Lower Footprint: Elevating Fine Chemicals with Sustainability in Mind 

Written by Endura | 30-10-2025

Endura is thrilled to announce the launch of PBO PRIME, a milestone innovation introduced in celebration of the company’s 45th anniversary. PBO PRIME is a premium, high-grade synergist, the first and only Piperonyl Butoxide (PBO) with the lowest levels of Dipiperonyl Methane (DPE) & Dipiperonyl Ether (DPM) impurities in the world, well below the threshold for potential classification as persistent, bioaccumulative, and toxic (PBT) and/or very persistent and very bioaccumulative (vPvB).  

PBT and vPvB classifications are based on the properties of the active substance and on the presence, over certain thresholds, of impurities classified as PBT and vPvB. While PBO itself is not a PBT nor a vPvB substance, the two potential impurities in PBO, DPM and DPE, could fulfill PBT and vPvB criteria. If confirmed to be PBT and vPvB, these two impurities when present in PBO at levels above the CLP threshold (Regulation (EC) No 1272/2008 on classification, labelling and packaging of substances and mixtures) could result in the classification of the PBO and/or any biocidal products containing the PBO, as PBT or vPvB.  The high-grade synergist, PBO Prime is also fully compliant with the Biocidal Products Regulation (BPR) approval of PBO.  

In 1999, Endura launched the 1st patented synthetic production of PBO in the world, through an environmentally conscious and sustainable process developed to avoid Sassafras tree deforestation.  

Today, thanks to its patent pending distillation process, Endura has taken another step towards a sustainable future, by reducing environmental impact thanks to minimum amounts of impurities which could be classified as persistent bioaccumulative and toxic (PBT) or very bioaccumulative (vPvB) .  

"We push the boundaries of knowledge and smart solutions through continuous improvement for PBO. Committed to responsible care and sustainability, we shape a future where innovation safeguards lives." Marianna Vollaro, CEO, Endura.
