Raw-material evidence for a skincare product file

Match each supplier file to the question it answers

Three PDFs with familiar names can still leave a raw material unidentified. Begin with the supplier, its exact material code, the material or blend name, the supplied grade and the batch where relevant. Link that identity to the product formulation revision. A trade name alone may not tell the assessor what is present in a supplied mixture.

The EU guidelines on Annex I discuss raw-material composition, specifications and impurities when preparing cosmetic safety information. They support obtaining relevant evidence, not assuming that every supplier document has the same purpose. The register below is a suggested working method; the specialist determines what is sufficient for the actual material and product.

Specification: what material is being supplied?

Use the specification or technical record to identify the intended material and the properties or acceptance criteria the supplier describes. Record its issue, issuer and scope. Ask whether it covers the purchased grade and whether a composition statement is needed for a mixture. Do not fill a missing composition field using a different supplier's similarly named product.

In the register, keep the specification reference separate from any batch result. An old specification attached to a new supplier code is an unresolved identity question until somebody checks the relationship.

Certificate of analysis: which batch and which results?

A certificate of analysis, or COA, ordinarily reports information for an identified batch against stated tests or criteria. Inspect what the actual certificate says: the material code, batch, methods or referenced methods, results, units and authorisation. The heading COA alone does not establish its scope or reliability.

Record a mismatch explicitly. A certificate for batch LOT-016 cannot demonstrate the reported results for LOT-017 simply because both deliveries came from the same supplier. Agree the purchasing and QC response with the responsible person for that activity rather than changing the batch reference in the index.

Safety data sheet: what information does this file provide?

Keep the SDS as a distinct document type and record its revision, supplied identity and intended use. Read the actual sections and identify the question being answered. Do not treat the existence of an SDS as a finished cosmetic safety assessment or presume that it discloses a mixture's full formulation.

The GB official guidance distinguishes product safety information from the assessor's conclusions. This guide does not determine whether an SDS must be supplied in a particular transaction. That chemicals-law question requires its own applicable source and review.

Synthetic material RM-017: a mismatch worth keeping visible

In the worked register, fictional supplier Example Supplier sends specification issue 2 for grade RM-017, an SDS issue 3 and a COA marked LOT-016. The receipt record refers to LOT-017. All three files are present, but the COA-to-receipt link remains unresolved. No real supplier documents or analytical results are represented.

The sample owner has three actions: request the matching batch record; obtain the composition information requested by the assessor; and confirm which product revision uses the material. The specialist finding stays blank. Completing the request is different from deciding whether the returned evidence is suitable.

Hand over the evidence with its limits

Give the reviewer the supplier code, applicable formulation, exact files and open questions. Record whether each file is present, identity-matched, checked for completeness and considered by the specialist. These are separate states. If the supplier or grade changes, open a new review question and preserve the earlier evidence link.

For Ireland/EU use the EU source branch; for GB use the GB source branch. Northern Ireland needs its own scope confirmation. Use D00 for the product-file task index and the evidence workspace to retain file identities. Related supplier, ingredient and QC guides become links only when they are released.
