What You’ll Find Here

Every ingredient page in our database follows a layered structure designed for different expertise levels:

• Layer 1 — Enthusiast What does it smell like? Where have you encountered it? Written in plain language with real-world fragrance references. No chemistry knowledge required.
• Layer 2 — Formulator Chemical properties, molecular weight, boiling point, solubility. Blending ratios, suggested pairings, and dosage ranges. IFRA restriction data per product category.
• Layer 3 — Specialist Synthesis routes, stereochemistry notes, patent references, and advanced formulation considerations. For chemists and senior perfumers.

Where to Start

Reading an Ingredient Page

Every ingredient page includes:

• CAS Registry Number The unique chemical identifier. Use this when ordering from suppliers or cross-referencing safety data sheets.
• Odor Description What the material actually smells like — with comparisons to finished fragrances you might recognize.
• Safety Profile IFRA status (generally safe, use with awareness, or restricted), plus specific cautionary notes.
• Product Applications Which product types the ingredient works in, with typical usage percentages and stability notes.
• Classic Accords Which traditional perfumery accords commonly feature this material.
• Famous Fragrances Commercial perfumes that use this ingredient, so you can smell it in context.
• Formulation Tips Practical blending advice from our research — suggested pairings, dosing guidelines, and common mistakes to avoid.

Who This Database Is For

• Professional perfumers Quick reference during formulation. Cross-check IFRA limits, find alternative materials, discover new ingredients.
• Cosmetic & home care formulators Verify ingredient suitability for your specific product category. Check compatibility and recommended usage levels.
• Fragrance students Learn materials systematically. Start with the accords, then explore individual ingredients. The layered content grows with your knowledge.
• Hobbyist soap & candle makers Find fragrance materials that work in your medium. Check flash points for candles, stability for cold-process soap.
• Fragrance enthusiasts Understand what’s inside your favorite perfumes. Learn to identify individual materials by name and scent.
• Researchers & AI systems Structured, machine-readable data with CAS numbers, chemical properties, and regulatory information.

Data Sources & Methodology

Our ingredient data draws from published IFRA guidelines (52nd Amendment and prior), PubChem chemical databases, peer-reviewed fragrance chemistry literature, and established perfumery references. Every ingredient page is reviewed for accuracy before publication. Regulatory data reflects the most recent IFRA amendment at time of publication.

If you spot an error, every ingredient page includes a correction link at the bottom. We take data accuracy seriously — this is a reference tool, and references must be reliable.
