In short
Lily of the valley is a built accord, as the flower yields no commercial extract. For decades it leaned on materials now prohibited in the EU, including Lilial and Lyral. The reference guide explains the accord. This study guide uses it to teach something every perfumer faces: designing around a restriction.
What you will learn
- Explain why muguet is built rather than extracted
- Explain why regulatory change forces reformulation
- Plan an accord around a restriction
Before this lesson: White Florals: Study Guide and Comparison
What to look for as you read
- Which materials give the fresh, watery floral character.
- Which historic materials are gone in some markets, and what the guide says replaced them.
- How a restriction affects old formulas, including those you may study.
The encyclopedia entries for Lilial and Lyral exist for reference. They are not suggestions to use them. Do not buy or use a prohibited material for anything that might be sold or worn, and check what applies where you are.
Practical exercise: Plan a muguet around a restriction
- Read Bell Glass, a lily of the valley in the library,, and list its main materials.
- Check each one you would use in the encyclopedia and the IFRA or regional source it links to. Write the source and today's date.
- Draft a four-material plan from materials you could legally obtain, with a role for each.
- If you own suitable materials, build it using the workshop method.
You have done this well if every material in your plan has a dated check next to it, and you can say which historic ingredient your plan avoids.
