How we work

From controlled formula to documented release.

Every batch we produce moves through the same controlled sequence from formula to release. The steps below describe how a sample formulation becomes a documented, released lot.

Production & QC flow

The public architecture of our process.

This sequence applies to every product we manufacture, whatever the formulation. It is how we ensure that what we ship matches what was specified, lot after lot.

Controlled sequence

Controlled formula and bill of materials

Each formulation is defined in our master formula database and produced against a controlled bill of materials. If a production document and the master formula disagree, the master formula governs and engineering is notified. Only approved raw materials may be used.

Unique lot number and full traceability

Each batch receives a unique lot number recorded in a controlled log, capturing the supplier lot numbers and the actual mass of every raw material used.

Clean, controlled handling

Equipment is verified clean before each batch to prevent cross-contamination, and moisture-sensitive formulations are handled under inert-gas blanketing.

Controlled addition and blending

Raw materials are added to the formulation, then blended to a homogeneous state. No substitution is ever permitted without engineering and client approval.

In-process sampling

A quality control sample is drawn after final inspection and sealed before the batch is closed, then held for 5 years for reference, if testing is ever needed.

Release testing against defined criteria

Finished product is tested against defined acceptance criteria, and verification that the constituent proportions fall within tolerance of the formula targets. Results are recorded against the lot.

Hold, quarantine, and corrective action

Any lot outside its acceptance criteria is placed on hold and quarantined and will not ship until engineering and quality authorize disposition. Out-of-specification results trigger a documented root-cause investigation and corrective action.

Batch release by Quality Control

Products are only released after every acceptance criterion has been met, and only after authorization by our Quality Control department.

Retention samples and retained records

A sealed retention sample is held for every lot for a minimum of five years, and the production record is retained with the order.

Change control and customer notification

Any change to raw materials, suppliers, methods, equipment, test methods, packaging, or manufacturing location requires internal approval and customer notification where applicable before shipment.
