<p>D.O.R.C.s PFCL manufacturing method uses a proprietary and stringent production and purification process. &bull; These ensure removal of critical impurities (H-value &le; 10ppm, 1H-value (for Octane only) &le; 1ppm). &bull; Verification of purity levels is confirmed using analytical methods specifically developed to detect critical impurities. &bull; Using independent analytical methods - sourcing of raw materials is continuously controlled. &bull; Deploying a multi-step purification process.</p>
