3-ETHYL-3,7-DIMETHYLOCT-6-ENAL

Description

3-Ethyl-3,7-dimethyloct-6-enal, also known as Lyral, is a synthetic fragrance ingredient commonly used in skincare and personal care products. This colorless to pale yellow liquid possesses a fresh, floral scent reminiscent of lily of the valley. Its molecular structure allows for slow evaporation, providing long-lasting fragrance in formulations.

In skincare applications, 3-Ethyl-3,7-dimethyloct-6-enal is primarily utilized for its pleasant aroma, contributing to the overall sensory experience of products. However, it's important to note that this ingredient has been associated with contact allergies in some individuals. As a result, its use has been restricted in the European Union, with a maximum concentration of 0.01% allowed in leave-on products and 0.02% in rinse-off products.

Formulators should exercise caution when incorporating this ingredient, particularly in products intended for sensitive skin. Alternatives such as hydroxycitronellal or lilial may be considered for similar olfactory effects. When used appropriately and in compliance with regulatory guidelines, 3-Ethyl-3,7-dimethyloct-6-enal can enhance the fragrance profile of skincare formulations without compromising safety or efficacy.
