Turn percentages into a batch you can weigh

Percentages are scale-free. Grams are not. A formula that reads well at ten grams can hide a line of 0.02 g that your scale only resolves at a larger batch, and a five-hundred-gram batch can demand a material you only own forty grams of. Batch production takes a target weight and multiplies every line so the proportions stay the ones you wrote. You choose the weight to match the vessel, the order you are filling, and the smallest quantity you can weigh without pretending.

Look at the smallest line before you commit. If the scaled amount is below what the scale can repeat, either make a larger batch or pre-dilute that material and enter the dilution as its own formula line. Rounding every line to a convenient number and then ignoring the drift is how a scaled perfume stops smelling like the trial. The tool shows the grams. You still decide whether those grams are honest on your bench. Write down the weight you actually add when it differs from the target, so the batch record matches the bottle.

Order of addition is part of making the batch, even though it is not a percentage. Large solvents and high-dose materials go in first. Solids, resins, and thick absolutes are warmed with a portion of solvent until they are clear, then returned to the main beaker. Do not heat the entire batch to dissolve one gum. Stir until the concentrate is uniform, then dilute to the strength you intend to judge. A concentrate sniffed from the cap is a different product from the alcohol solution your client will wear.

Logging the batch is what connects the formula to stock and to cost. The materials decline by the grams you used. The batch keeps the date, the total weight, and any note about haze, insolubles, or a substitution you had to make. That note is the difference between a repeatable product and a one-off that smelled right for reasons you cannot reconstruct. If the smell of a large batch is not the smell of the trial, suspect heat, order, and evaporation before you rewrite the formula. Save a new version only when you intend the percentages themselves to change.

Scale in steps when a formula is new. A hundred grams teaches you more than a kilo you may have to discard, and it is enough to evaluate top, heart, and drydown on blotters over a day. Woods, musks, and resins often need that day. Citrus and light herbs can be judged sooner, then checked again after the drydown in case the base has swallowed them. The free plan can record the batches that fit your formula allowance. The habit that matters is the same at any plan: one formula version, one target weight, one written result.

Common questions

How do I scale a formula to a different batch size?

Enter the total target weight (e.g. 500 g) and ScentLabs recalculates every ingredient proportionally. The olfactive balance is preserved exactly — only the total weight changes. You can also scale by a simple multiplier (e.g. ×10) if you prefer.

Does batch production track raw material usage?

Yes. When you log a completed batch, you can choose to automatically deduct the quantities used from your raw material stock. This keeps your inventory accurate without manual entry.

Can I view a formula's production history?

Yes. Every batch logged is recorded in the formula's production history with date, batch size, notes, and the stock state at the time of production. This gives you a complete audit trail.
