RUŌOD Lab Academy

The perfumery curriculum

Twelve levels in four stages, then 6 specialist tracks and 5 mastery and research courses. Where things stand: 200 lessons and 64 study guides are published.

Stage A: Foundations

Learn what perfumery is, train your nose, and set up a safe and organized bench.

Level 1: Introduction to Perfumery

What perfumery is, how a perfume is structured, the words the trade uses, and a realistic plan for learning it. Outcome: A smelling journal and a personal learning plan.

The craft and its people

Reading a fragrance

Starting well

Level 2: Olfactory Training

How smell works, how to evaluate a material properly, and the drills that build recognition, vocabulary and reliability. Outcome: Documented evaluations of a starter collection of materials.

Stage B: Formulation

Build accords, do the arithmetic of a formula, and compose complete fragrances.

Level 4: Accord Construction

From two-material studies to balanced accords, troubleshooting what will not resolve. Outcome: Several original accords, each documented and reproducible.

Fixing accords

Level 5: Perfume Mathematics and Formula Design

Weight-based formulation, active material, normalization, scaling, substitution and records that let a formula be repeated. Outcome: Formulas you can calculate, scale and reproduce.

Level 6: Complete Perfume Creation

Turning a concept into a formula: the opening, the heart, the drydown, then iteration, maturation and evaluation. Outcome: Several complete fragrances, each with its development record.

From idea to first draft

Building the structure

Composing by family

Iteration

Maturation and evaluation

Stage C: Advanced Craft

Understand chemistry and analysis, measure performance, and work with modern materials.

Level 7: Perfume Chemistry and Analytical Methods

The organic chemistry a perfumer uses, how structure relates to odor, degradation, and what GC-MS can and cannot tell you. Outcome: A material dossier linking structure, behavior and an analytical reading.

Organic chemistry for perfumers

Structure and odor

Physical chemistry at the bench

Level 8: Performance Engineering and Evaluation

Projection, longevity, bloom, intensity and stability, and how to test them without fooling yourself. Outcome: A controlled performance test with its data and its limitations stated.

What performance means

Testing with controls

Stability

Substrates

Level 9: Modern and Experimental Perfumery

Modern musks, woody ambers, transparent florals, high-impact materials, biotech ingredients and experimental design. Outcome: An experimental composition with a written rationale.

The modern palette

Impact and minimalism

New ingredients

Experimental design

Stage D: Professional Practice

Work within regulation, answer commercial briefs, and present a portfolio.

Level 10: Safety, IFRA, Regulatory Compliance and Quality

IFRA Standards, allergens, phototoxicity and regional rules, with each claim tied to its current primary source. Outcome: A compliance review of one of your own formulas, marked with what a qualified assessor must confirm.

IFRA Standards

Specific hazards

Regional frameworks

Quality and documentation

Level 11: Commercial Fragrance Development

Reading briefs, working to cost, sourcing, reformulating, testing and presenting to a client. Outcome: A response to a mock brief within a stated cost, with revisions recorded.

The brief

Cost and sourcing

Manufacture and reformulation

Presenting and revising

Level 12: Professional Portfolio and Capstone

An independent project from research and concept through formula, cost and regulatory review to a professional case study. Outcome: A capstone fragrance and a portfolio case study. Completing it does not confer a qualification.

Independent project

Review

Presenting your work

Specialist Tracks

Go deeper in one direction after the core levels, ending in a specialist project.

Analytical Perfumery

Deeper GC-MS and headspace work: method choices, reading real data, and what reconstruction can honestly claim. Requires: Level 7. Outcome: An analytical dossier on one natural material, built from published data, stating what the data can and cannot show.

The instrument

Working with real data

Linking instrument and nose

Molecular Perfumery

Structure-odor relationships, stereochemistry and the literature behind modern aroma chemicals. Requires: Level 7. Outcome: A literature review of one odor family, relating structure to odor and marking where the evidence runs out.

Structure-odor case studies

Chirality and receptors

Prediction

Creative Mastery

Sustained composition practice: studies of style, restraint and complexity, with structured critique. Requires: Level 6. Outcome: A short collection of three related compositions with a written account of each decision and a structured critique.

Discipline

Understanding style

Critique and finish

Research and Innovation

How to design, run and report a fragrance experiment that someone else could check. Requires: Level 9. Outcome: A complete research report on a small fragrance question, with its design, data and limitations stated so that someone else could check it.

Asking a question

Designing the test

Reporting

Industrial and Functional Fragrances

Fragrance for soap, detergent, home and personal care: bases, stability and dosage in the product. Requires: Level 8. Outcome: A written adaptation plan taking one fragrance into two product bases, with its test plan and the checks it still needs.

How a base changes a fragrance

Product families

Bringing it to product

Regulatory and Quality Specialization

Compliance and quality systems in depth, kept to current primary sources and dated. Requires: Level 10. Outcome: A quality and compliance file for one of your own fragrances, marked with what a qualified person must confirm.

The compliance file

Quality systems

Across markets

Mastery and Research

Advanced courses for experienced perfumers and researchers: derivations, data, open questions and professional briefs, each ending in a research or professional project.

Advanced Perfumery Chemistry

Vapor-liquid equilibrium, evaporation, odor activity, autoxidation, reactions in ethanol and mass spectra, derived. Requires: Level 7, the Molecular Perfumery track and the Analytical Perfumery track. Outcome: A research dossier predicting how one material behaves in a formula from its physical chemistry, tested against published data, with every assumption named.

Outcome: A statistical study of one accord, from a mixture design through panel data to a model, with its uncertainty budget and its limitations stated.

The algebra of a formula

Measurement and inference

Software and Computational Perfumery

Formula data models, Python checks, version diffs, molecular descriptors, model validation and the RUŌOD Lab app, precisely. Requires: Level 5. Outcome: A tested calculation script that reproduces an app’s figures for a real formula, a versioned record of that formula, and a written critique of one published odor-prediction model.

Outcome: An original research capstone presented as a professional submission, with its evidence, costs, constraints and open questions. It confers no qualification.

Inside development

Leading the work

The syllabus changes as lessons are written. A planned lesson may be merged, split or dropped if research shows a better way to teach it. Completing the Academy confers no qualification; for formal training routes see How to Learn Perfumery.
