For DIY perfumers

Why DIY perfumers use Scent Inventory

Lost track of formulas?

Store every version of your creations and stop searching through notes and spreadsheets.

IFRA checks take forever?

See available Category 4 guidance alongside your formula, adjusted to the dosage in your finished perfume.

No idea what your formulas cost?

With Studio, calculate material costs from the prices recorded for your selected batches.

Inventory chaos?

Track materials, dilutions and production history in one clean workflow.

How it works

From raw material to repeatable production.

  1. 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. 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. 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. 4 · Iterate & reproduce

    Compare formulation versions, revisit production history and reuse your batch choices for the next trial.

Features

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.

Formulas & accords

Build formulas from individual materials or expandable accords. With Studio, produce an accord and bring it back into your stock.

Stock & dilutions

Formulator and Studio keep your materials, batches and fixed dilutions together. Studio accounts for the selected dilution when calculating weighing amounts.

Versions & formula PDFs

Organize materials by top, heart, base, musk or modifier. Keep formulation versions and export a clear formula PDF.

Detailed material profiles

Search by name, manufacturer or CAS and explore practical odor, effect and use information, with unverified data clearly marked.

Production & history

Studio brings weighing amounts, batch choices, stock deductions and production records into one workflow. Cost totals depend on your recorded prices.

Learn & exchange

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.

The global raw material library

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.

Built by a hobby perfumer.
