What Is Lilial (Lysmeral)?
Once found everywhere from soap shelves to the most expensive floral compositions, it is now a warning sign. Lilial — chemical name Butylphenyl Methylpropional (BMHCA), trade name Lysmeral — was the backbone of the muguet (lily of the valley) note for decades. But this page is not a usage guide; it is a farewell and compliance audit guide.
How Does It Smell?
- ✓ Fresh lily of the valley — white, watery florals
- ✓ Light green, freshly cut stem quality
- ✓ Powdery and clean
- ✓ A faint soapy brightness in the background
- ✓ Opens in the heart note, "illuminates" the composition
- ✓ High diffusion — noticeable even in small quantities
It is easy to understand why it was so beloved: the muguet note cannot be distilled from nature (lily of the valley yields no essential oil), so it must always be reconstructed synthetically. Lilial was the cheapest and brightest building block of this artificial flower. What fills that gap today is the heart of this article.
💭 What Did It Evoke & Where Was It Used?
A molecule's legacy lies not only in its scent but in the associations it triggers. Lilial constructed a feeling of "cleanliness."
Cleanliness · Freshness · White florals · Transparency · Softness · Modern brightness
This is why it was fundamental not only in fine fragrances but also in soaps, detergents, fabric softeners and personal care products. It was the hidden architect of that "freshly washed laundry" sensation.
🧴 In Which Fragrance Types Was It Used?
Both designer and niche; across feminine and masculine categories alike, especially at the muguet heart of fresh-floral and fougère structures. The three names below are examples of iconic uses from their era (described in our own words):
- Drakkar Noir — clean floral brightness within a masculine fougère skeleton.
- Cool Water — a muguet-fresh bridge in an aquatic-fougère structure.
- Classic Lily of the Valley-themed feminines — as the central muguet ingredient.
Current formulas of these products have been reformulated without Lilial. If you still see old-dated stock on a label, treat it as a warning sign.
Classification and the Ban Process
The ban did not happen overnight. Scientific assessment, classification and legislative implementation — three distinct layers. Understanding the process means building an early-warning system for manufacturers.
| Stage | What happened? | Outcome |
|---|---|---|
| CLP classification | BMHCA was assigned to the CMR 1B — reproductive toxicant category | Automatic restriction triggered for cosmetic use |
| EU Cosmetics Regulation amendment | CMR 1B substances were moved to the prohibited list (Annex II) of the Cosmetics Regulation | Legal basis for the ban established |
| Entry into force — March 2022 | Ban on placing the substance on the market took effect | Use in new products is prohibited |
| TİTCK compliance | Turkey operates legislation aligned with the EU Cosmetics Regulation | Binding for domestic manufacturers as well |
Currency disclaimer: Regulatory texts, transition periods and supplementary provisions are subject to change. Always verify the current EU Cosmetics Regulation Annex II and TİTCK publications before making any production or import decisions.

Formula Audit Protocol for Manufacturers
A prohibited substance can be present in your formula "hidden" without your knowledge — because it may be contained within a ready-made muguet base purchased from a supplier. The responsibility is yours. Here is a step-by-step audit.
- Take a raw material inventory
List all fragrance oils and base compositions you use. Include not only pure molecules but also pre-made accords sourced from suppliers.
- Search by CAS number
In the safety data sheet (SDS) of every raw material, search for CAS 80-54-6 or the terms "Butylphenyl Methylpropional / Lysmeral / BMHCA." Due to the variety of trade names in use, rely solely on the CAS number.
- Request a compliance declaration from your supplier
For every fragrance oil, obtain a current IFRA compliance certificate and a written "BMHCA-free" declaration. Verbal confirmation is not sufficient.
- Check the allergen/INCI disclosure
If Butylphenyl Methylpropional appears in the allergen list provided for label declaration, that formula is outdated — request the updated version.
- Clear your stock
If you hold any old-dated bases or finished products containing Lilial, do not place them on the market. Physically segregate and label them.
- Plan reformulation
Rebuild the muguet character you have lost using the alternatives listed below. The goal is not to mimic the scent exactly but to reconstruct the overall balance.
Current Alternatives & Frequently Asked Questions
The good news: the industry filled this gap quickly. Lilial's demise gave rise to a new generation of molecules in muguet chemistry. None is an exact copy — each brings its own signature.
| Alternative | Supplier / type | Character | Notes |
|---|---|---|---|
| Nympheal | Givaudan | Rich, natural muguet + light aquatic | One of the strongest structural responses to Lilial; high quality |
| Florosa (Florol) | Firmenich | Fresh, watery-green lily | Transparent and clean; good diffusion |
| Lilybelle | IFF | Creamy-floral muguet | Soft, powdery bridging effect |
| Mayol / Cyclamen Aldehyde | Various | Green-floral, watery | Supporting molecule in muguet accords |
If you want to anchor the muguet accord on a woody-ambery base, polycyclic musks such as Tonalide or a balsamic base character such as Labdanum absolute will add depth; for a modern warmth with pheromone-like qualities, active ingredients of the Sensfeel type are also worth considering.
