Short answer
A perfume batch record documents one occasion a formula was made. It names the formula code and approved version, the batch code, size and scale factor, and for every material: the target weight, the actual weight, the dilution and the lot used. It records the alcohol, the date and who made it, the mixing, resting, chilling and filtering, the checks made against the reference, the yield, and the release decision. It is a separate record from the formula, and it is what makes a batch traceable.
Formula record vs batch record
The formula is the recipe; it changes only by becoming a new version. A batch record is what happened on one day: actual weights, the lots that were on the shelf, the conditions. Keeping them separate is what lets you answer "which bottles contain lot L2026-117 of the bergamot?" and "why does batch 14 smell different from batch 13?" — and why overwriting a formula with the weights you actually achieved is such a damaging habit. The formula's own structure is described in the perfume formula template.
The sections of a batch record
1. Identification
- Batch code (unique, never reused), product name.
- Formula code and version, and its approved status.
- Batch size (finished product) and concentration; concentrate and alcohol targets; scale factor.
- Date started, operator, checker.
2. Materials
| Material | Dilution | Lot | Target (g) | Actual (g) | Initials |
|---|---|---|---|---|---|
| Bergamot oil FCF | 100% | L2026-117 | 29.52 | 29.54 | |
| Hedione | 100% | H-0921 | 44.28 | 44.28 | |
| Ambroxan in DPG | 10% | Dil. 2026-09-30 (parent lot A-552) | 14.76 | 14.77 |
Every row records the dilution and, for dilutions, which preparation was used and its parent lot. The actual weight is written at the balance, as it is read.
3. Solvent and finished product
- Alcohol: supplier, grade or denaturant, lot; target and actual weight.
- Water, if used: target and actual.
- Calculated actual concentration from actual weights.
4. Process
- Order of addition followed (or deviations noted).
- Mixing method and time; solids fully dissolved.
- Resting: start and end dates, container, storage conditions.
- Chilling and filtering: temperature, duration, filter type.
5. Checks and release
- Appearance (color, clarity) compared with the reference.
- Odor compared with the retained reference on blotters.
- Yield: weight obtained versus expected; losses noted.
- Units filled, fill weight checked on a sample of units.
- Retained sample taken and labeled.
- Release decision, date and signature.
6. Deviations
Anything that did not go to plan: an overshoot, a substituted lot, a longer rest, a failed check. Record what happened, what was done, and who decided.
Why actual weights matter
A record of targets proves nothing about what is in the bottle. Actual weights, together with lots, are what let you investigate a complaint or a batch that smells different, and they are the evidence a safety assessor or regulator would expect to see behind a product. How to make the same perfume twice explains how batch records are used to find the cause of a difference.
Preparing the batch sheet
Generate the target weights from the approved formula version, never by retyping. The scaling arithmetic is in how to scale a perfume formula. Before weighing, check stock of every material and dilution in the quantities needed, and that the smallest target weight suits the balance.
When someone else makes the batch
If a contract manufacturer makes your product, they will run their own batch records, but you need to agree what they record and what you receive — at minimum the formula version, lots and release checks. How to prepare a perfume formula for production handover covers that agreement.
Designing the batch code, and tracing a material lot forward to every batch that used it, is covered in perfume batch numbers and lot codes.
Frequently asked questions
How long should batch records be kept?
At least as long as the product may be on the market and any regulatory retention period for your market. In Great Britain, the Product Information File — which includes manufacturing information — is kept for 10 years after the last batch is made available.
Do I need a batch record for a small handmade run?
If you sell it, yes. A one-page record takes a few minutes and is what lets you trace a problem back to its cause.
