ACETALDEHYDE ETHYL HEXENYL ACETAL

Description

Acetaldehyde Ethyl Hexenyl Acetal is a versatile synthetic ingredient used in haircare formulations, primarily as a fragrance component. This colorless liquid compound is characterized by its fresh, green, and fruity odor profile, reminiscent of cucumber and melon notes. Its molecular structure allows for slow release of fragrance, providing long-lasting scent in hair products.

In haircare formulations, Acetaldehyde Ethyl Hexenyl Acetal serves multiple purposes beyond its olfactory properties. It acts as a solvent, helping to dissolve and blend other ingredients effectively. This compound also functions as a fixative, enhancing the longevity of fragrances in shampoos, conditioners, and styling products.

The ingredient's low molecular weight enables it to penetrate the hair shaft, potentially contributing to improved product performance. It is often used in conjunction with other fragrance molecules to create complex, layered scents in haircare products. Acetaldehyde Ethyl Hexenyl Acetal is generally considered safe for use in cosmetic formulations when used at appropriate concentrations, typically below 1% in rinse-off products and 0.3% in leave-on products. However, as with any synthetic ingredient, patch testing is recommended for individuals with sensitive skin or scalp conditions.
