Corrections and updates
How Trebalm handles errors, what we log, and the public record of substantive corrections made to published pages.
Trebalm publishes numbers that people use to make things. Getting one wrong has consequences, so corrections are handled in public.
The policy
- Substantive corrections are logged. If a fact, figure, formula, safety statement or conclusion changes, the change is made on the page and recorded here with the date and a plain description of what was wrong.
- Silent edits are limited to typography. Spelling, punctuation, a broken link, a clumsy sentence: fixed without a log entry, because logging them would bury the entries that matter.
- Nothing is quietly deleted. If new evidence overturns something we published, the section is rewritten and the change is described rather than removed.
- Safety corrections are made immediately on receipt of credible information, before any further checking of the surrounding page.
- Review dates are honest. The "updated" date on an article means somebody read that page on that day. We do not refresh dates to look current.
How to report an error
Tell us what the page says, what you believe is correct, and ideally where that comes from. Corrections that cite a standard, a paper or a supplier specification are the fastest to act on, but a clear description of a formula that did not behave as written is just as welcome, because that usually means the page is unclear even if the numbers are right. Details are on the contact page.
We are particularly glad to hear about: percentages that do not total 100, gram columns that do not match their batch weight, a temperature that produced a different result in your workshop, a regulatory statement that is out of date, and any citation that does not resolve.
The log
Trebalm published its first full set of pages on 6 September 2026. No substantive corrections have been logged yet. When the first one is made it will appear here, newest first, with the page, the date, and what changed.
Each entry will state four things: which page, the date of the correction, what the page previously said, and what it says now with the reason for the change.
Scheduled reviews
Some pages go stale by default rather than by error, so they are re-checked on a cycle regardless of whether anyone reports a problem:
| Page type | Review cycle | Why |
|---|---|---|
| Regulatory and labelling | Every six months, and on any known rule change | Requirements and deadlines move, and a stale compliance page is worse than none |
| Safety limits | Annually | Fragrance and allergen standards are revised periodically |
| Materials data | Annually | New analyses and standards revisions |
| Formulas and troubleshooting | As reader feedback arrives | The physics does not change, but our explanations of it can improve |
Our wider approach to sourcing and uncertainty is set out in the editorial standards and the methodology note.
