Butylphenyl Methylpropional is a synthetic fragrance compound that is used in cosmetics. It is also known as p-tert-butyl-alpha-methylhydrocinnamic aldehyde, a colorless liquid with a strong floral scent.
Butylphenyl Methylpropional is a common ingredient in aftershave lotions, shampoos and perfumes. The use of this substance in cosmetics is closely regulated, as it is considered an allergen in Europe. This substance is more commonly known as Lilial or lily aldehyde and has the potential to cause contact dermatitis in sensitive individuals. It is identified by its fragrance, which is modeled after the lilac flower and is also used in the essential oil ylang-ylang.
