3-METHYL-4-(3,5,6-TRIMETHYL-3-CYCLOHEXENYL)-3-BUTEN-2-ONE

Description

3-Methyl-4-(3,5,6-trimethyl-3-cyclohexenyl)-3-buten-2-one, also known as α-Isomethyl Ionone, is a synthetic fragrance ingredient commonly used in both skincare and haircare formulations. This compound belongs to the family of ionones, which are cyclic ketones that impart a distinctive woody, floral scent reminiscent of violets and orris root.

In skincare and haircare products, α-Isomethyl Ionone serves primarily as a fragrance enhancer, contributing to the overall sensory experience of the product. Its molecular structure allows for a long-lasting scent that slowly releases over time, providing a persistent yet subtle aroma. The ingredient is often used in leave-on products such as lotions, creams, and hair serums.

While primarily utilized for its olfactory properties, α-Isomethyl Ionone may also contribute to masking less pleasant odors associated with certain active ingredients. It is important to note that, as with many fragrance components, this ingredient may cause skin sensitization in some individuals. Formulators typically use it in concentrations below 0.1% to minimize potential adverse reactions while still achieving the desired scent profile.
