铃兰醛

Also known as lilial, BMHCA, 3-(4-tert-butylphenyl)-2-methylpropanal

Lilial (a trade name for lily aldehyde, also known as lysmeral or lilestralis) is a chemical compound commonly used as a perfume in cosmetic preparations and laundry powders, often under the name butylphenyl methylpropional. It is an aromatic aldehyde, naturally occurring in crow-dipper and tomato plants, and produced synthetically in large scale. It was banned for use in cosmetics by the EU in March 2022 after being found to be harmful to fertility.
