4-TERT-BUTYLDIHYDROCINNAMALDEHYDE

Description

4-Tert-butyldihydrocinnamaldehyde, also known as Bourgeonal, is a synthetic aromatic aldehyde commonly used in both skincare and haircare formulations. This versatile ingredient is prized for its fresh, floral scent reminiscent of lily of the valley, making it a popular choice in fragrance compositions for various personal care products.

In skincare, 4-tert-butyldihydrocinnamaldehyde serves primarily as a fragrance ingredient, imparting a pleasant aroma to creams, lotions, and serums. Its molecular structure allows for good stability in various formulations, ensuring the scent remains consistent over time. While its main function is olfactory, some studies suggest it may have mild antimicrobial properties, potentially contributing to product preservation.

In haircare, this compound is utilized in shampoos, conditioners, and styling products to enhance the overall sensory experience. Its clean, floral notes can help mask less desirable odors from other functional ingredients. Additionally, 4-tert-butyldihydrocinnamaldehyde has been shown to have some hair growth-promoting effects in vitro, though more research is needed to confirm its efficacy in vivo.
