Batch & bottling
Take a formula into production with a carrier, a process-loss allowance, and a bottle fill weight.

From formula to batch and cost
Start in the formula builder with the materials you actually have, including the strength of each stock. Enter relative parts and a target concentrate mass to produce a weighing sheet. A diluted stock contributes both aromatic material and solvent, so the builder reports its weighed quantity separately from its neat contribution. Save a named revision before changing the formula you intend to compare or produce.
Send that revision to the batch planner to choose a finished-product concentrate dose, allow for process loss, and calculate the number of complete bottles. Bottle fill is entered as mass. Continue to the cost calculator to include carrier, packaging, labour, and overhead. The tools pass a copy of the formula and batch figures between these steps, allowing you to trace the estimate back to a specific revision.
Keep the inputs and observations together
Use the dilution calculator when you need a weaker stock from a known starting strength. Use the ingredient-limit tool to calculate contributions against a limit you supply from applicable documentation. The latter is an arithmetic aid; it does not retrieve restrictions, identify every constituent in a natural material, or certify a finished formula. Read the worked example and units before entering your own quantities.
The blotter journal records how a material or formula changes over time and can retain an attached formula snapshot. Saved formulas, studies, and drafts remain in this browser. Export JSON backups before clearing website data or moving to another browser or domain. CSV exports provide readable spreadsheet records, while the downloads page offers blank worksheets for weighing and recording observations away from the screen.
