A precision scale reading to 0.01 g, glass beakers and pipettes, perfumer's alcohol for dilution, and small storage bottles. That's enough to make every formula on the site.

All materials are stocked by the major hobby-perfumery suppliers across the US, EU, UK and Australia. Each material includes its CAS number for unambiguous ordering, and our Ingredients Guide lists trusted suppliers by region.

Formulas are given per 100 g of concentrate, and the on-screen calculator scales to any batch size. Diluted to around 20% in perfumer's alcohol, a 100 g concentrate batch makes roughly 500 g of finished eau de parfum.

Freshly mixed concentrates often smell harsh and disjointed. Maceration — resting the blend in a cool, dark place for two to four weeks — lets the materials marry and is essential, especially for amber and oriental formulas.

No. Every formula is an original reconstruction — our own interpretation built to evoke the character of a well-known fragrance for personal, educational use. We are not affiliated with any fragrance house, and brand names are used only to describe the style a formula explores.

Yes, for personal use. Fragrance scents are not protected by copyright, and our formulas are original — not the houses' confidential formulae. Trademarks protect names and logos, which is why we say 'inspired by' and never use brand logos. If you intend to sell, avoid trademarked names and check IFRA limits.

Each formula includes IFRA notes. Percentages describe the concentrate; skin-level exposure depends on the final dilution. For any product you sell or gift, check current IFRA Standards for restricted materials. For personal use, always patch-test and follow supplier safety data.
