Cosmetic ingredient documentation: what to request, and what each document proves

Every document in a cosmetic raw-material pack answers exactly one question, and most sourcing errors come from asking a document to prove something outside its scope. This page states what each document proves, what it does not, and what to verify on receipt.

The short answer

Every document in a raw-material pack answers exactly one question, and almost every sourcing dispute comes from asking a document to prove something outside its scope. Only one of them — the certificate of analysis — is evidence about the material actually in your warehouse, and only if it carries a lot number, a test date and an identified issuer. Everything else describes a grade, communicates a hazard, or records a supplier's declaration.

This page describes what documents contain. It is not legal or regulatory advice, it does not establish that any material is permitted or suitable, and it does not restate Health Canada requirements as permission. Classification and claims decide your obligations, and they are yours to determine.

Under Canada's Cosmetic Regulations the notification and labelling obligations sit with the finished-product manufacturer or importer, not with the raw-material supplier. A supplier can give you evidence about the material; it cannot discharge your obligation for the product.

Step 1 · What each document proves — and what it does not

Read the scope line first. It tells you whether the document is about a lot, a grade, or a position.

  • Certificate of Analysis (CoA)

    Lot-specific evidence

    Answers: What did this identified lot actually test at, against the specification it was sold under?

    • Does not answer: It says nothing about any other lot, past or future.
    • Does not answer: It is not proof of cosmetic suitability, permitted use, or safety.
    • Does not answer: It does not replace a specification sheet — it reports results against limits set elsewhere.

    Must contain

    • · Lot or batch number matching the material delivered
    • · Date of manufacture and date of analysis
    • · The tested parameters with results and the specification limits beside them
    • · Test method reference for each parameter
    • · Identified issuer, with a signature or named release authority

    Request it: At every delivery, matched to the lot actually received.

  • Specification Sheet

    Grade-level, not lot evidence

    Answers: What limits is this grade sold against, on which parameters, by which methods?

    • Does not answer: It reports nothing about the lot in your warehouse — that is the certificate's job.
    • Does not answer: It does not establish equivalence with another supplier's grade unless the parameters and methods match.

    Must contain

    • · Full parameter list with upper and lower limits
    • · Test method for each parameter, since the same parameter measured differently is not comparable
    • · Appearance, assay or active content, and moisture where relevant
    • · Revision number and date

    Request it: Before the first purchase, and again whenever the revision changes.

  • Safety Data Sheet (SDS)

    Hazard communication

    Answers: What are the hazards of this material and how should it be handled, stored, transported and dealt with in an emergency?

    • Does not answer: It is a hazard-communication document, not a quality document.
    • Does not answer: It does not establish cosmetic suitability and is not a substitute for a certificate or a specification.
    • Does not answer: Absence of a listed hazard is not a statement about cosmetic safety in use.

    Must contain

    • · All sixteen sections of the standardised GHS format used under WHMIS 2015
    • · Revision date, so you can tell whether it is current
    • · Supplier identification and an emergency contact

    Request it: Before the material arrives on site, and refreshed whenever the supplier revises it.

  • Technical Data Sheet (TDS)

    Grade-level, not lot evidence

    Answers: What are the physical and functional properties of this grade, including active or solids content and handling guidance?

    • Does not answer: Supplier guidance on typical use is not a specification and is not a guarantee of performance.
    • Does not answer: It is not lot evidence.

    Must contain

    • · Active content or solids, stated explicitly — this is what makes two grades comparable
    • · Solubility, pH of a stated solution, and appearance
    • · Handling and storage guidance
    • · Revision date

    Request it: During evaluation, and before any grade substitution.

  • INCI Declaration

    Written declaration

    Answers: What is the INCI name or names of everything in this raw material, including carriers and any preservative it already contains?

    • Does not answer: An INCI name identifies a substance; it does not tell you the grade, the active content, or the quality.
    • Does not answer: Two materials sharing an INCI name are not therefore interchangeable.

    Must contain

    • · Every constituent, in the correct INCI nomenclature
    • · Any carrier, solvent or preservative present in the supplied material
    • · The proportion basis, where the material is a blend

    Request it: Before the finished-product ingredient list is drafted — a hidden carrier or preservative changes your label.

  • Allergen Declaration

    Written declaration

    Answers: Does this material contain, or is it processed alongside, substances that your market requires to be declared?

    • Does not answer: It is a declaration about the material, not an assessment of your finished product.
    • Does not answer: Its absence is not evidence of absence — never infer allergen status from silence.

    Must contain

    • · An explicit statement, positive or negative, for each substance in question
    • · Whether the statement covers cross-contact in shared production
    • · Signature and date from the supplier

    Request it: Before listing the material, especially for plant-derived and protein-derived materials.

  • Origin / Source Declaration

    Written declaration

    Answers: Where does this material come from — country of manufacture, and whether it is plant, animal, mineral or synthetic in origin?

    • Does not answer: It is not a certification. If a certified scheme is required, the certificate is a separate document.
    • Does not answer: Country of manufacture and country of the trading entity are different things; ask for both explicitly.

    Must contain

    • · Country of manufacture of the material itself
    • · Botanical, animal, mineral or synthetic derivation
    • · Any scheme certificate referenced, attached rather than named

    Request it: Whenever origin appears on your label, in your claims, or in a customer specification.

  • Animal-Testing Statement

    Written declaration

    Answers: What is the supplier's written position on animal testing for this material?

    • Does not answer: A supplier statement is a representation, not a verified audit.
    • Does not answer: It does not qualify your finished product for any third-party programme, which has its own criteria.

    Must contain

    • · The scope of the statement — the material, the supplier, or the whole chain
    • · Date and signature

    Request it: Where you intend to make or support a corresponding position on the finished product.

Step 2 · The document pack, by stage

Ask for grade-level documents early and lot evidence at delivery — not the other way round.

  • Evaluation — deciding whether to trial the material

    Specification Sheet · Technical Data Sheet · Safety Data Sheet · INCI Declaration

    Grade-generic documents. Enough to decide whether the material can work and can be handled safely.

  • Qualification — approving the material and the supplier

    Specification Sheet · INCI Declaration · Allergen Declaration · Origin / Source Declaration · Animal-Testing Statement

    Declarations are collected here, in writing, before the material reaches a label.

  • Delivery — receiving and releasing a lot

    Certificate of Analysis · Safety Data Sheet

    Lot-specific evidence plus current hazard communication. Run the receiving checks against it.

Step 3 · Receiving checks

Six checks that turn a document pack into something verifiable at the door.

  • The lot number on the certificate matches the lot number on the drums received.

    A certificate for a different lot is evidence about material you do not have.

    If it fails: Treat the material as unqualified and request the correct lot certificate before release.

  • Every reported result on the certificate sits inside the specification limits.

    A certificate can be complete and still show an out-of-specification result.

    If it fails: Raise it with the supplier before use; a concession, if any, is a documented decision.

  • Test methods are stated, and match the methods on the specification.

    Same parameter, different method, different number. This is where second-source comparisons break.

    If it fails: Ask for the method reference before treating two grades as comparable.

  • Active or solids content is stated, not implied.

    Solution-supplied materials are dosed on active. Without the figure the formula cannot be set correctly.

    If it fails: Request the figure from the technical data sheet and confirm it on the certificate.

  • The safety data sheet on file is the current revision.

    An outdated sheet is a workplace hazard-communication gap.

    If it fails: Request the current revision and replace the file copy.

  • Allergen and origin positions are held as written declarations, not as email assurances.

    Declarations follow the material into your product file and onto your label.

    If it fails: Obtain the signed declaration before the material is listed.

Step 4 · Qualifying a second source

Documentation can establish comparability of a material. Only trial establishes behaviour in your formula.

  • Same INCI, plus the same carrier set

    A matching INCI name is the starting point, not the answer. Compare the full declaration, including carriers and any preservative already present.

  • Active or solids content compared on the same basis

    Two grades quoted at the same price per kilogram can deliver very different amounts of the actual functional material.

  • Specification parameters and test methods compared line by line

    Where methods differ, the numbers are not comparable and the grades cannot be declared equivalent on paper.

  • Declarations re-obtained for the new source

    Origin, allergen and testing declarations are supplier-specific and do not transfer.

  • Formula trial and stability re-run

    Documentation can establish comparability of the material. Only trial establishes behaviour in your formula.

Where this bites, in materials you actually buy

Each line is a document field that changes what you receive.

  • Preservatives are frequently supplied as blends. The INCI declaration, not the trade name, tells you what appears on your label.

    Phenoxyethanol

  • For a salt sold against a compendial specification, assay and the identified test method are what make two offers comparable.

    Potassium Sorbate

  • Grade designation and specification are different things; the specification sheet is what states the limits you are buying against.

    Sodium Benzoate

  • Chelants exist in acid and salt forms under related names. The INCI declaration resolves which one is being quoted.

    Disodium EDTA

  • Anhydrous and monohydrate forms carry different assay bases. Read the specification before comparing prices.

    Citric Acid (Anhydrous & Monohydrate)

  • Where a material can be vegetable or synthetic, the origin declaration is the only record of which one you received.

    Glycerin

  • Protein-derived materials attract allergen and origin questions from customers; hold both declarations in writing.

    Hydrolyzed Wheat Protein

  • Where a material is supplied as an ester or a blend, active content on the technical data sheet is the comparison basis.

    Vitamin E Acetate

Scope note

No statement here is a claim about any particular supplier's documentation, including our own.

What this page does not determine

  • · It does not establish that any material is permitted, safe, or suitable for your product. Documentation is evidence, not approval.
  • · A complete document pack does not make a product compliant. Classification and claims decide the requirements, and they are your responsibility.
  • · It is not legal or regulatory advice, and it does not restate Health Canada requirements as permission.
  • · It makes no claim about any supplier's documentation, including our own.
  • · It does not certify grade equivalence between two suppliers. Comparison is done on the specification, on actives and on test methods.

Use this when

  • You are opening an account with a new supplier and need to define the document pack up front.
  • A certificate arrived without a lot number or a test date and you need to know whether it counts as evidence.
  • You are assembling a product file and need to know which obligations sit with you rather than with the supplier.
  • You are qualifying a second source and need the documents that make two grades comparable.

How this decision is structured

  • Each document is described by the question it answers, so scope is explicit.
  • Lot-specific evidence is separated from generic sheets — that distinction is the core of the page.
  • Obligations are attributed: the finished-product manufacturer or importer carries the notification and labelling duty, not the raw-material supplier.
  • Origin, allergen and animal-testing declarations are treated as declarations to obtain in writing, never as inferences.
  • A receiving check list turns the document pack into something verifiable at delivery.

What this page does not determine

  • It does not establish that any material is permitted, safe, or suitable for your product. Documentation is evidence, not approval.

Ask for a quotation or a specification

Where this comes from, and what it cannot tell you

  • Canada's Cosmetic Regulations under the Food and Drugs Act, and Health Canada's Cosmetic Notification Form requirement

    Supports: That a cosmetic sold in Canada is subject to notification to Health Canada and to ingredient-disclosure and labelling obligations, and that the finished-product manufacturer or importer carries those obligations — not the raw-material supplier.

    Limitation: This describes the existence of the obligations, not how they apply to your specific product. Classification (cosmetic, natural health product or drug) is decided by the product's composition and its claims, and it changes the requirements entirely.

    Canada · Verify against the current Health Canada guidance before you rely on it.

  • Certificate of analysis and specification practice in chemical supply

    Supports: That a certificate of analysis reports tested values for one identified lot against a specification, and that a specification sheet states the limits the material is sold against. The two documents answer different questions.

    Limitation: A certificate of analysis is evidence about the lot it names. It is not evidence about future lots, and a document without a lot number, test date and identified issuer cannot be treated as lot evidence at all.

    International · Request a lot-specific certificate at each delivery.

  • WHMIS 2015 / Hazardous Products Regulations safety data sheet requirements in Canada (16-section GHS format)

    Supports: That a safety data sheet in Canada follows the standardised 16-section format and is a hazard-communication document for the workplace.

    Limitation: A safety data sheet communicates hazard and handling. It is not a quality document, not proof of cosmetic suitability, and not a substitute for a certificate of analysis or a specification.

    Canada · Suppliers are expected to provide a current sheet; check the revision date.

  • INCI nomenclature and the supplier certificate of analysis for the specific grade

    Supports: That an INCI name identifies a substance but not its grade, active matter, supply form or impurity profile — those come from the certificate of analysis and the technical data sheet.

    Limitation: Two materials sharing an INCI name can differ in active matter and behaviour. Nothing here substitutes for the documentation of the lot you buy.

    International · Request current documentation for each lot.

  • Health Canada — Cosmetic Ingredient Hotlist

    Supports: That restricted and prohibited substances in cosmetics sold in Canada are defined by the Hotlist, and that the Hotlist entry — not this page — is the authority for any concentration limit or labelling condition.

    Limitation: The Hotlist states restrictions. It never states that an unrestricted ingredient is effective, safe in your formula, or approved for your product.

    Canada · Consult the current published Hotlist before every formulation decision.
