For decades, Piperonyl Butoxide (PBO) has been the reference synergist in insecticide formulations worldwide. By enhancing the efficacy of pyrethrins, synthetic pyrethroids and other insecticide classes, PBO has played a central role in pest control, particularly in managing resistant insect populations.
Today, however, the expectations placed on PBO are evolving. Performance alone is no longer sufficient.
Formulators, brand owners and regulators are increasingly looking for solutions that combine efficacy, sustainability, supply reliability and long‑term regulatory resilience. In this context, PBO Prime represents a decisive step forward.
From Performance to Substance Profile: A Regulatory Shift
Recent amendments to the European CLP Regulation have introduced new hazard classes, including PBT (Persistent, Bioaccumulative and Toxic) and vPvB (very Persistent and very Bioaccumulative).
Under this framework, substances placed on the EU market will continuously be evaluated not only for their intrinsic properties, but also for the presence of specific impurities above defined thresholds.
While PBO itself is not classified as PBT or vPvB, regulatory assessments have identified two potential impurities, Dipiperonyl Methane (DPM) and Dipiperonyl Ether (DPE), as substances that could potentially meet PBT criteria if present above threshold levels.
This marks a fundamental shift: the focus is no longer simply on PBO, but on PBO quality, impurity control and manufacturing consistency.
Why Natural PBO Grades Face Structural Limits
Many traditional PBO grades rely on raw materials derived from natural sources historically linked to safrole extraction. While technically effective, this approach presents increasing challenges:
PBO Prime was not conceived as a simple premium grade.
It has been developed as a forward‑looking solution to address both regulatory evolution and market expectations.
Endura’s objective was clear: to deliver a high‑purity Piperonyl Butoxide with maximum control over impurities, enabling customers to confidently future‑proof their formulations.
This has been achieved through:
The result is PBO Prime: a high‑grade PBO characterized by exceptional purity, ultra‑low levels of DPM and DPE, and no potential PBT or vPvB classification under CLP.

A Strategic Choice for Future‑Ready Portfolios
PBO Prime is not about forcing immediate change.
It is about offering choice, a future‑ready option for customers who prefer to anticipate regulatory evolution rather than react to it.
In a market increasingly focused on substance profiles, impurity management and lifecycle impact, PBO Prime enables customers to:
Choosing PBO Prime means transforming regulatory awareness into a competitive advantage, while continuing to rely on the proven performance of PBO as a synergist.
