2-METHYL-4-(2,6,6-TRIMETHYL-2-CYCLOHEXENYL)-2-BUTENAL

Description

2-Methyl-4-(2,6,6-trimethyl-2-cyclohexenyl)-2-butenal, also known as Lyral, is a synthetic fragrance ingredient commonly used in various skincare and personal care products. This colorless to pale yellow liquid has a fresh, floral scent reminiscent of lily of the valley. Its molecular structure allows for a long-lasting fragrance profile, making it a popular choice in formulations.

In skincare applications, Lyral is primarily utilized for its pleasant aroma, contributing to the overall sensory experience of products. It is often found in moisturizers, serums, and body lotions. However, it's important to note that Lyral has been associated with contact allergies in some individuals, leading to its restricted use in certain markets.

The European Union has implemented regulations limiting its concentration in leave-on products to 0.01% and 0.02% in rinse-off products. Formulators should be aware of these restrictions and consider alternative fragrance ingredients for sensitive skin formulations. Despite its limitations, when used within recommended guidelines, Lyral can enhance the olfactory appeal of skincare products without compromising their primary functions.
