Why DIY perfumers use Scent Inventory
Store every version of your creations and stop searching through notes and spreadsheets.
See available Category 4 guidance alongside your formula, adjusted to the dosage in your finished perfume.
With Studio, calculate material costs from the prices recorded for your selected batches.
Track materials, dilutions and production history in one clean workflow.
From raw material to repeatable production.
- 1 · Discover your palette
Search the global library by name, maker or CAS. Explore odor profiles, formula roles and practical guidance before adding materials to your palette.
- 2 · Build formulas
Compose in percentages, group materials by note and build with accords. Keep versions of your ideas and scale the whole formula to 100%.
- 3 · Produce & deduct stock
With Formulator, scale to your target grams and select your batches and dilutions. With Studio, stock is deducted when you finish production, not while experimenting.
- 4 · Iterate & reproduce
Compare formulation versions, revisit production history and reuse your batch choices for the next trial.
Everything you need at the bench.
Begin with learning and composition. Add your own materials and the Make perfume calculator with Formulator, or stock deduction and costs with Studio.
Build formulas from individual materials or expandable accords. With Studio, produce an accord and bring it back into your stock.
Formulator and Studio keep your materials, batches and fixed dilutions together. Studio accounts for the selected dilution when calculating weighing amounts.
Organize materials by top, heart, base, musk or modifier. Keep formulation versions and export a clear formula PDF.
Search by name, manufacturer or CAS and explore practical odor, effect and use information, with unverified data clearly marked.
Studio brings weighing amounts, batch choices, stock deductions and production records into one workflow. Cost totals depend on your recorded prices.
Read the first three guide chapters free, buy the complete guide for €1.99 once, and explore free learning formulas. Formulator and Studio also include community access.
Understand what each material brings.
Go beyond a name and CAS number. Explore odor facets, effects in a formula, behavior, pairings and available safety documents. Add materials without entering stock or prices; track batches later with Formulator or Studio.
