4-METHYL-2-PHENYL-2-PENTENAL

Description

4-Methyl-2-phenyl-2-pentenal, also known by its trade name Lyral, is a synthetic fragrance ingredient commonly used in skincare and personal care products. This clear, colorless to pale yellow liquid possesses a delicate, floral scent reminiscent of lily of the valley. Its molecular structure allows for excellent stability in various formulations, making it a versatile choice for perfumers and cosmetic chemists.

In skincare applications, 4-methyl-2-phenyl-2-pentenal is primarily utilized for its pleasant aroma, contributing to the overall sensory experience of products. While not an active ingredient for skin benefits, it can enhance user compliance and satisfaction with skincare routines. However, it's important to note that this compound has been identified as a potential allergen for some individuals, particularly those with sensitive skin.

Recent regulations in the European Union have restricted the use of Lyral due to its allergenic potential. Formulators are now exploring alternative fragrance ingredients to replace 4-methyl-2-phenyl-2-pentenal in skincare products. When used, it is typically found in concentrations below 1% to minimize the risk of adverse reactions while still imparting its characteristic scent.
