Overview
Lilial, chemically known as Butylphenyl Methylpropional, is a synthetic aromatic aldehyde prized for its floral, lily-like scent. Developed as a fragrance ingredient, it is a staple in modern perfumery due to its stability and versatility. The compound is synthesized through chemical processes that ensure consistency in quality and scent profile. First introduced in the mid-20th century, Lilial quickly became popular in both fine fragrances and functional products like soaps and detergents. Its ability to blend well with other fragrance components makes it a favorite among perfumers. Despite its synthetic origin, it replicates the natural aroma of lily of the valley, a flower often challenging to extract in commercial quantities.
Physical and Chemical Properties
Lilial is a colorless to pale yellow liquid with a molecular weight of 204.31 g/mol. Its density is approximately 0.96 g/cm³ at 20°C, and it boils at 258°C. The compound is insoluble in water but dissolves readily in alcohols and oils, making it suitable for a wide range of cosmetic formulations. Chemically, Lilial is stable under normal conditions but may degrade when exposed to strong oxidizing agents. Its low volatility ensures a lasting fragrance, which is why it is often used in products requiring sustained scent release. The compound’s stability also contributes to its long shelf life when stored properly in airtight containers away from heat and light.
Main Applications
Lilial is predominantly used in the fragrance industry, where it imparts a fresh, floral note to perfumes, colognes, and body care products. It is a key ingredient in many floral and oriental fragrance compositions, often paired with other aldehydes or musks to enhance complexity. Beyond perfumery, Lilial is incorporated into household products such as laundry detergents, fabric softeners, and air fresheners. Its stability in alkaline environments makes it ideal for soaps and cleaning agents. In cosmetics, it is found in lotions, shampoos, and other personal care items, though formulations must adhere to regional regulations regarding concentration limits due to potential skin sensitivity.
Safety and Storage
While Lilial is generally safe for use in regulated concentrations, it can cause skin irritation or allergic reactions in sensitive individuals. Proper handling includes wearing gloves and eye protection, especially in industrial settings. The compound should be stored in a cool, dry place, away from direct sunlight and heat sources to prevent degradation. Regulatory bodies like the International Fragrance Association (IFRA) provide guidelines on safe usage levels in consumer products. In the EU, Lilial has been classified as a potential skin sensitizer, leading to restrictions in certain applications. Manufacturers must ensure compliance with local regulations and provide safety data sheets (SDS) to buyers.
B2B Procurement Guide
When sourcing Lilial, B2B buyers should prioritize suppliers with certifications such as ISO or GMP, ensuring product quality and traceability. Key procurement considerations include verifying the CAS number (80-54-6) and requesting certificates of analysis (CoA) to confirm purity, typically 98% or higher. Price negotiations should account for order volume, with bulk purchases often attracting discounts. Buyers should also inquire about packaging options—Lilial is commonly supplied in drums or intermediate bulk containers (IBCs). Due to evolving regulations, especially in Europe, it’s advisable to stay updated on legal restrictions and explore alternatives if necessary.
