Lilial[2]
Overview
Lilial is a synthetic aromatic aldehyde prized for its fresh, floral scent resembling lily of the valley. Developed as a cost-effective alternative to natural musk, it has become a staple in modern perfumery and personal care formulations. Its stability and versatility make it suitable for a wide range of products, from fine fragrances to household cleaners. As a fragrance intermediate, Lilial is often blended with other aroma chemicals to create complex olfactory profiles. Its use is governed by industry standards such as IFRA (International Fragrance Association) due to allergenic potential at high concentrations.
Physical and Chemical Properties
Lilial is a clear, slightly viscous liquid with a characteristic floral odor. Its molecular structure includes a tert-butyl group attached to a phenyl ring, contributing to its low volatility and persistence in formulations. The compound exhibits good solubility in organic solvents and oils but is insoluble in water, making it ideal for oil-based fragrance applications. Under standard conditions, Lilial is chemically stable but may degrade upon prolonged exposure to strong acids or oxidizers. Its boiling point of 258°C allows it to retain its scent in high-temperature processes like soap manufacturing.
Main Applications
The primary use of Lilial is in the fragrance industry, where it imparts a fresh, floral note to perfumes, body lotions, and hair care products. It is particularly valued in lily-of-the-valley and white floral accords. Beyond fine fragrances, it is incorporated into functional products like detergents and fabric softeners for its odor-masking properties. In cosmetics, Lilial appears in concentrations typically below 1% to comply with safety regulations. Recent regulatory changes, such as its classification under EU REACH as a Category 1B reproductive toxicant, have led to reformulations in some markets.
Safety and Storage
Lilial requires careful handling due to its potential to cause skin sensitization. Personal protective equipment (PPE) including gloves and goggles is recommended during bulk processing. The compound should be stored in airtight containers away from heat sources and incompatible materials like strong oxidizers. Regulatory status varies by region: while the EU has restricted its use in cosmetics since 2022, other markets may still permit it with concentration limits. Manufacturers must ensure Safety Data Sheets (SDS) are updated according to the latest hazard classifications.
B2B Procurement Guide
When sourcing Lilial, buyers should prioritize suppliers who provide full regulatory documentation, including Certificate of Analysis (CoA) and IFRA compliance statements. Due to evolving regulations, verify whether alternatives like Hydroxycitronellal are required for specific end markets. Bulk pricing typically decreases for orders above 100kg, with discounts available for long-term contracts. Consider testing stability in your specific formulation, as performance may vary with pH levels and other ingredients. Logistics should account for its classification as a non-hazardous chemical (for transport) under normal conditions.
