2-METHYL-4-(2,6,6-TRIMETHYL-2-CYCLOHEXENYL)-3-BUTENAL

Description

2-Methyl-4-(2,6,6-trimethyl-2-cyclohexenyl)-3-butenal, also known as Lyral, is a synthetic fragrance ingredient commonly used in skincare and personal care products. This colorless to pale yellow liquid has 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.

Lyral belongs to the aldehyde chemical family and is known for its ability to impart a fresh, green, and slightly woody aroma to skincare products. It is often used in concentrations ranging from 0.1% to 1% in leave-on products and up to 2% in rinse-off formulations. This ingredient helps to mask unpleasant odors associated with certain active ingredients, enhancing the overall sensory experience of skincare products.

However, it's important to note that Lyral has been identified as a potential allergen for some individuals. As a result, its use in cosmetic products is regulated in many countries, with some regions requiring its declaration on product labels when used above certain concentrations. Formulators should consider alternative fragrance options for products intended for sensitive skin or when aiming for hypoallergenic formulations.
