Quick Answer
Before sourcing bio-based cosmetic packaging, define the exact component, resin grade and basis of the proposed bio-based content claim. Biomass origin, biodegradability, recycled content and recyclability are separate questions. Request evidence tied to the ordered material, then validate the finished pack with the actual formula.
A supplier’s plant-based brochure does not tell you whether the whole bottle, just its body, or only part of its resin is covered. Resolve that scope before artwork is approved, rather than after the claim has been printed.
Separate origin from end of life
European Bioplastics distinguishes bio-based and biodegradable properties. A bio-based origin is not, by itself, evidence that a finished cosmetic pack biodegrades or belongs in a composting system. Likewise, a recycled-content statement does not describe the feedstock’s biological origin.
Keep each intended statement in a separate row in the project brief. For each row, list its scope, evidence owner and review status. Avoid combining several unverified benefits into a general eco-friendly promise.
Ask what the percentage measures
Request the supplier’s precise resin grade and an explanation of any percentage. Is it a statement about bio-based carbon, component mass, a particular constituent, or an allocation system? Do not treat unlike measurement bases as interchangeable. Record the method, issuing organization, material identity and validity of the supporting document.
List exclusions such as caps, pump parts, colorants, coatings and labels. A body-level statement must not silently become a whole-pack claim. Ask the responsible reviewer to approve wording only within the evidence’s scope.
Build a material change trial
Origin does not eliminate the need for engineering approval. Obtain production-intent components in the proposed grade. Review processing requirements with the component maker, then check dimensions, closure engagement, decoration and filled-pack compatibility under the agreed plan.
If an existing pack is the reference, keep its geometry and fill configuration documented so the comparison has a clear baseline. Do not assume a resin with a similar name can be substituted without review.
Preserve procurement traceability
The purchase specification should name the accepted grade and supporting evidence, not merely bio-plastic. Agree how a lot is linked to that specification and who must notify the buyer of a substitute. Keep claim review separate from commercial approval: a quotation accepted for trials is not approval of consumer-facing artwork.
Create a claim-to-component evidence table
Write the proposed public statement beside the precise component it describes. Include exclusions and the measurement basis supplied by the material provider. A claim register should preserve the wording under review, not reduce different statements to one general green label.
| Field | What to record | Question before approval |
|---|---|---|
| Claimed component | Body, cap or other identified part | Does the wording extend beyond this scope? |
| Material identity | Supplier grade and revision | Does the evidence name this grade? |
| Measurement basis | Method and meaning of any percentage | Are comparisons on the same basis? |
| Order linkage | Purchase specification and lot evidence | Can the supplied part be traced? |
Assign separate review statuses to engineering suitability and claim support. A resin may be accepted for a component trial while its proposed artwork wording remains unresolved. Keeping those decisions distinct prevents an early sampling decision from becoming public claim approval.
Resolve a body-level statement before artwork release
For example, a supplier document may cover the selected bottle-body resin while a mockup describes the entire pump pack as plant-based. This illustrative mismatch requires a scope review, not simply a new logo. Identify the other parts and ask which evidence, if any, covers them.
The responsible reviewer should narrow the statement or request the missing support. Keep the revised wording and exclusions with the artwork reference. Do not invent a whole-pack percentage by combining documents that use different measurement bases.
Control a substitute grade at procurement
When an alternative material is offered, request its exact identity and changed evidence before accepting it as equivalent. Route engineering changes to the component and formula teams; route wording changes to the responsible claims reviewer. Document both decisions even if the part still looks the same.
Keep the accepted material reference in the purchase specification and define how a supplied lot is linked to it. A brochure retained from the first enquiry is not a substitute for an order-specific identity. The handover should also state who must notify the buyer when a grade or evidence scope changes.
End-of-life statements remain outside a bio-based-origin approval unless separately reviewed. This record structure is a procurement aid, not a legal determination or evidence that Oulete holds a particular environmental certification.
FAQ
Does bio-based mean compostable? No. Ask for separately applicable evidence and the intended disposal conditions.
Can a resin statement cover a multi-part pump bottle? Not without checking every component and the claimed scope.
