Controlled formula & bill of materials
Each formulation is held in the master formula database under revision control and produced against an approved bill of materials.
How we work
From controlled formula to documented release.
Every batch moves through the same controlled sequence. It is how we make sure that what we ship matches what was specified, lot after lot.

Production & QC flow
The public architecture of our process.
Distilled from Proxima's internal production and quality-control procedures. Client, product, raw-material, and numeric-limit specifics are intentionally omitted for confidentiality.
Controlled sequence
Unique lot & full traceability
Each batch receives a unique lot number recording supplier lots and the actual mass of every raw material used.
Clean, controlled handling
Equipment is verified clean before each batch. Moisture-sensitive formulations are handled under inert-gas blanketing.
Controlled addition & blending
Raw materials are added with no substitution without engineering approval, then blended to a homogeneous state.
In-process sampling
A quality-control sample is drawn at the defined process point and sealed for testing and retention.
Release testing
Finished product is tested against defined acceptance criteria, including moisture reported in PPM and formula tolerances.
Hold & corrective action
Any lot outside acceptance criteria is quarantined. Out-of-specification results trigger documented investigation and corrective action.
Release by Quality Control
Only Quality Control authorizes release, after every acceptance criterion has been met.
Retention samples & records
A sealed retention sample is held for every lot for a minimum of three years, with the production record.
Change control
Changes to materials, methods, equipment, tests, packaging, or manufacturing location require approval and customer notification where applicable.
Bring us the requirement.
We will help define the controlled path to a released, documented lot.
