# Post-Consumer Resin (PCR) Decontamination & FDA/EU Food-Grade Traceability in Cosmetics
TL;DR — Recycled-content resin is usable in cosmetics packaging only when two things travel together: a decontamination and cleaning discipline at the feedstock level, and a lot-level traceability record that links batch, process window, and test results per project. The material program records five PCR grades (PP, PET, PETG, ABS, AS) as recycled-content variants; the decontamination steps below are qualitative industry practice, configured per project. Compliance status is not part of the published record; any food-contact or regulatory claim requires project-level documentation and evidence. Traceability is the tool that lets a customer assemble that documentation — it is not a standing approval.
Why: Availability Is a Process and a Record, Not a Label
- A recycled feedstock is a used feedstock first. Contamination begins at the point of collection; how it is removed is decided before the resin ever reaches a mold;
- The decontamination chain is an industry process, not a product spec. Sorting, washing, and melt-stage grading are qualitative process steps whose parameters belong to the feedstock processor and are confirmed per project;
- Availability is a chain of evidence. What makes PCR usable on a given project is not the grade name — it is the lot record linking batch, process window, and test results;
- Traceability mirrors the percentage discipline. A recycled-content percentage is recorded only where project or specification evidence exists; a lot trace similarly means nothing until its records exist;
- The FDA/EU axis lands on documentation, not on a pre-existing approval. The question the buyer should ask is not "is this material food-grade?" but "what evidence does this project need to assemble for a compliance review?"
How: The Decontamination Chain, the Lot Record, and the Regulatory Boundary
3.1 The decontamination chain: qualitative industry practice
Post-consumer feedstock differs from virgin material primarily in what it carries: other resin types, label and adhesive residue, colorants, and process leftovers. The conventional chain, described at industry-practice level:
- Feedstock is sorted by resin family so that the melt chemistry stays predictable;
- The selected fraction is cleaned — washing steps that remove the majority of surface contamination;
- The cleaned material passes through melt-stage grading — staged filtration and classification that narrows the contaminant remaining in the pellet;
- The resulting recycled-content pellet enters molding as a controlled lot.
Every parameter in that chain — temperatures, dwell times, filter ratings, sorting thresholds — belongs to the feedstock processor and is confirmed against project requirements, not published here. What the program records is the outcome: which grades are available as recycled-content variants and which application families they serve.
3.2 The evidence chain: lot, window, tests
The usable unit of recycled-content material is the lot, not the grade name. A project-side traceability record therefore carries three layers, all configured per project:
- The lot identity — which delivery, which processor, which production date;
- The process window — how this lot was dried, molded, and validated inside the project's confirmed window;
- The test record — which quality checks were run on this lot and the result against the project criteria.
This is the same architecture as the recycled-content percentage rule: a number appears only where project or specification evidence records it. Without the three layers, a barrel of PCR is an untested input; with them, it is a documented input.
3.3 The traceability record and the compliance documentation package
For a customer whose project touches food-contact or similarly regulated territory, the deliverable is a documentation package, not a label. The same lot record feeds both directions: batch identity, process window, and test results are exactly what a compliance review wants to see assembled. The program's role is to keep that record structured per project, so the customer's own technical team (or a qualified third party) can review it against the applicable framework.
3.4 The regulatory boundary, stated plainly
Compliance status is not part of the published record; any food-contact or regulatory claim requires project-level documentation and evidence. Regulatory programs such as the US FDA food-contact framework and the EU's food-contact rules are real and relevant — but engaging with them is a project activity: assembling the material and process evidence, arranging the appropriate review with the customer and qualified parties, and recording the outcome per project. This program does not publish a standing food-contact approval for any material, PCR or otherwise.
3.5 Molding the lot inside our manufacturing system
Once the lot and the window are accepted, molding follows the established route: injection molding, blow molding, mold/tooling development, and mass production are recorded capabilities of our manufacturing system, and recycled-content runs inside the same system with the same discipline as virgin grades — plus the lot confirmation loop described in the PCR processing insight linked below.

What: Recorded Program Data and the Verification Hooks
- Materials (recorded): PCR PP, PCR PET, PCR PETG, PCR ABS, and PCR AS are registered as recycled-content variants of the corresponding standard grades, each supporting Bottle, Airless, Jar, Pump, and Cap applications;
- Percentage discipline (recorded): the recycled-content percentage is recorded per project; no fixed percentage is published, and a number appears only where project or specification evidence supports it;
- Capability note (recorded): the material records confirm recycled-content capability and a rising customer demand per project; the record deliberately stops short of end-of-life property claims;
- Quality program (capability-level): recycled-content material-related testing sits in the material-sustainability group of the quality program, with compatibility testing alongside — both recorded as capabilities, with no parameters published;
- Manufacturing system (capability-level): injection molding, blow molding, mold/tooling development, and mass production;
- What is not claimed: no decontamination parameters, no standing food-contact approval, no regulatory compliance status, no fixed recycled-content percentage.
Gotchas
- Decontamination is not a single published step. The chain is qualitative industry practice; specific temperatures, times, and filter ratings belong to the feedstock processor and are confirmed per project — do not quote them from a generic source.
- Traceability is lot-level, not grade-level. A grade name carries no evidence by itself; the lot record (identity, window, tests) is the unit of proof, and a new delivery is a new record.
- Compliance status is not part of the published record. Any food-contact or regulatory claim requires project-level documentation and evidence — plan the documentation workflow at project start rather than assuming a standing status exists.
- US and EU frameworks are different exercises. The applicable rule set, the required evidence, and the review arrangement differ; assume a per-project review with the customer and qualified parties, never a single universal label.
- Percentage and traceability share one discipline. If no project evidence exists, there is no percentage and no trace — the number and the record appear or disappear together.
- A new lot is a re-confirmation, not a re-stamp. Even an approved project re-confirms the window and re-runs the material-related checks on each fresh delivery before mass production.
- Keep the claim inside the capability note. A traceable lot record says what was done on that lot; it does not extend to end-of-life or broader material behavior — the record stays within recycled-content availability.
