Ingredients and additives: what comes with each
Four documents per ingredient, and the one that changes without warning forces you to redo labels.
A processed product with fifteen ingredients drags sixty documents behind it, and they are not interchangeable: each answers a different question and expires differently. Conflating them is what makes a company believe its documentation is current when what it holds is three years old.
The four per ingredient
| Document | What it answers | How often it changes |
|---|---|---|
| Technical datasheet | What it is, composition and intended use | When the supplier reformulates |
| Allergen declaration | What it contains and what it may contain | With the datasheet, and sometimes silently |
| Certificate of analysis | What that specific batch tested as | With every batch |
| Supplier certifications | Their quality scheme or status | Annually, and it lapses without warning |
Important
The third row is the only one that runs **per batch** and the worst filed, because it arrives with the goods rather than with supplier onboarding. If the certificate of analysis is filed by supplier and not linked to the batch that came in, it exists but is useless: when a problem needs narrowing, you cannot say which analysis belongs to the material actually used.
The change that forces you to review everything else
Watch out
A supplier can reformulate an ingredient while still supplying "the same thing" commercially: same name, same code, new datasheet. And that new datasheet may carry a different allergen or a "may contain" that was not there before. **That change does not arrive as an alert, it arrives as a PDF attached to a routine email** — and if nobody compares it with the previous version, your labels stop being true without anyone deciding it.
How to organise it so that shows up
- 1
One datasheet per ingredient and supplier, versioned
Keeping the previous one: that is what lets you see what changed.
- 2
The certificate of analysis, linked to the intake batch
Not to the supplier. It is the difference between narrowing and estimating.
- 3
Which of your products use each ingredient
So that when one changes, you know how many labels to review.
- 4
And expiry warnings for supplier certifications
They get checked exactly when a large order or an audit lands.
What a customer audit asks for
The third distinguishes a system that works: holding the datasheets is not enough, you must be able to show that a change was detected and managed.
Worth knowing
Requirements for ingredient, allergen and additive information depend on the product, the market and the certification scheme you hold, and they get updated. **Confirm exactly what must appear and with what scope with your adviser or certifier**; this describes what documentation exists and how to keep it linked.
›Is the datasheet the salesperson sends enough?
As a reference yes; better the one quality or technical maintains, since that is the one updated.
›What about ingredients bought from a distributor?
Ask for the manufacturer's datasheet: the distributor passes it on, it does not issue it.
›How long must certificates of analysis be kept?
Longer than the shelf life of the product that batch went into.
A real case
The situation
A supplier reformulates an additive and sends the new datasheet in a routine email.
What you do
- Compares it with the previous version on receipt
- Reviews the products using that ingredient
What you get
Spots a new "may contain" and corrects four labels before they reach the market.
The situation
An ingredient's composition changes and nobody reviews anything.
What you do
- Asks the supplier to communicate any change
What you get
The change arrives before the wrong label does.
The situation
Documents for an ingredient are missing and it is used anyway.
What you do
- Checks what is missing before accepting intake
What you get
The gap shows on receipt rather than at the audit.
The situation
An ingredient's four documents sit in four places.
What you do
- Gathers them in the reference's file
What you get
They are consulted at once.
The situation
A client asks for a specific ingredient's sheet.
What you do
- Checks that reference's file
What you get
You answer without phoning the supplier.
The situation
A document expires with the ingredient in stock.
What you do
- Records validity on receipt
What you get
The warning arrives before it is used.
