- P&G’s 2025 study of PureCycle’s Ironton, Ohio plant found PureFive polypropylene achieved A3 (leave‑on cosmetic) CosPaTox rating across five finished lots.
- Study compared five household PCR feedstock lots to five finished resin lots, with all analyses performed in triplicate for statistical reliability.
- Dissolution recycling selectively dissolves polypropylene (#5), removing additives, colors and odors while retaining polymer performance and lowering CO₂ versus virgin production.
Study findings
A 2025 independent study by Procter & Gamble found PureCycle’s dissolution recycling produced PureFive polypropylene that met the A3 CosPaTox designation, the top category for leave‑on cosmetic products under the CosPaTox assessment framework.
Method and scope
Testing was performed at PureCycle’s full‑scale Ironton, Ohio facility, comparing five incoming household PCR polypropylene feedstock lots with five finished resin lots; all analyses were run in triplicate for statistical reliability.
Process description
The dissolution recycling method, developed by P&G and licensed to PureCycle, selectively dissolves polypropylene (#5) to separate it from additives, colors, odors and fillers, enabling removal of contaminants while maintaining the polymer itself.
Performance and environmental implications
PureFive resin retains the structural and performance characteristics of virgin polypropylene, making it suitable for high‑performance and safety‑sensitive applications, and the process is reported to lower CO₂ emissions relative to new plastic production while diverting waste from landfills.
