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,[2] 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.
