Short answer
Standardize formula documentation by writing a short set of house rules and applying them to every record: one code format for formulas and materials; one version rule; one unit per formula; one way of writing dilutions; a list of required fields; controlled lists for families, tags and statuses; date format and naming conventions; and a review step before anything is approved. Keep the rules on one page, put them where records are made, and check new records against them until the habits stick.
Why standardize — even alone
In a team, standards let people read each other's records. Working alone, they let you read your own records years later, when you have forgotten what "bg ok" meant. Standards also make records machine-readable, which matters the day you import them into new software or hand a formula to a manufacturer.
The house rules
| Topic | Example rule |
|---|---|
| Formula codes | Prefix + three-digit number, e.g. EX-031. Never reused. |
| Material codes | NAT- for naturals, AC- for aroma chemicals, BAS- for bases, + number. |
| Versions | Integers, never renumbered. Any change to materials, amounts or dilutions is a new version. |
| Units | Grams for trials; percentages to two decimals for approved formulas. |
| Dilutions | Separate field, never in the name; 100 for neat; never blank. Solvent named. |
| Required fields | Code, name, version, status, date, author, purpose; entries with material code, dilution and amount. |
| Statuses | Draft, Testing, Approved, Production, Archived. |
| Families and tags | From the agreed lists only. |
| Dates | YYYY-MM-DD everywhere. |
| Names | Specific material names (supplier/grade where it matters); no abbreviations outside the agreed list. |
| Approval | Approved versions are reviewed by a second person (or re-checked by you a day later) and locked. |
Common documentation mistakes in fragrance labs
- Dilutions missing or in names. The single most damaging omission — see formula %, absolute % and relative %.
- Overwritten formulas instead of new versions.
- Private abbreviations that nobody else, including your future self, can decode.
- Mixed units within one formula.
- Free-text families and tags that drift into duplicates.
- Notes kept apart from the formula they describe, so the link is lost.
- Batch actuals written over formula targets.
- Undated records.
Making the standard stick
- One page. A standard nobody reads is not a standard.
- Templates that enforce it. A formula template with a dilution column that cannot be skipped does more than a rule that says "record dilutions". See the perfume formula template.
- Controlled lists in the tool, not just on paper.
- A check at approval: a version is not approved until its record meets the standard.
- Fix old records gradually, starting with those in use.
- Review the standard yearly, and when something goes wrong.
Notebooks and libraries follow the same rules
The same codes and conventions should run through the lab notebook (how to keep a perfume lab notebook) and the formula library (how to organize a digital perfume formula library). A trial ID in the notebook, a formula code and version in the library, and a batch code on the shelf should all point at each other.
Standards and software
Software can enforce part of a standard: required fields, controlled lists, version numbers that cannot be renumbered, locks on approved formulas. RUŌOD Lab, for example, has formula codes, integer versions, a fixed set of five statuses, a fixed list of primary families you can extend, and locks; codes, naming and units remain conventions you decide and follow. How documentation standards fit into a small business's overall process is covered in building a fragrance development workflow.
Frequently asked questions
Is it worth standardizing old records?
For formulas still in use, yes. For historical experiments, an index and a scan is often enough. Don't let the size of the archive stop you applying the standard to new work today.
Who should own the standard?
One named person, even in a small team. Shared ownership usually means no ownership.
