Learn perfume formulation

Learn a practical perfume-formulation workflow, from writing a scent brief and choosing materials to weighing trials, evaluating blotters, and revising a formula.

Understand top, middle, and base notes as an evaporation framework, how the layers overlap, and how to build smoother transitions in a perfume formula.

A practical introduction to IFRA Standards, product categories, maximum acceptable concentrations, supplier certificates, amendments, and the limits of software checks.

Compare eau de toilette, eau de parfum, and extrait by concentration, structure, diffusion, wear, and formulation choices—not marketing labels alone.

Learn the difference between concentrate and finished-product percentages, calculate dilution and batch weights, and handle pre-diluted materials without losing track of active material.

Learn how the Jean Carles method uses systematic smelling, binary mixtures, proportion studies, and staged construction to train perfumers and clarify accords.

Diagnose short wear and improve perfume longevity through structure, material choice, fixatives, concentration, testing, and skin-safe formulation—not base notes alone.

Understand projection, sillage, diffusion, and scent trail, plus a practical method for testing and adjusting how a perfume occupies space.

Explore the roles of Ambroxan, Iso E Super, Hedione, and modern aroma chemicals, including diffusion, texture, anosmia, dosing, and responsible sourcing.

Build a floral accord by defining its flower, choosing a body and diffusive space, adding naturalistic traces, and evaluating proportion through controlled trials.

Learn the difference between classical and modern amber, then build warmth, resin, sweetness, wood, diffusion, and contrast into a balanced amber accord.

Compare natural extracts and synthetic aroma materials across odour complexity, consistency, safety, sustainability, performance, documentation, and creative use.
