In plain English

Tetralol is a man-made chemical that smells pleasant and is added to skincare and perfumes for its scent. It belongs to a family of compounds called tetralins, which are often used as fragrance ingredients. Because it's synthetic, it doesn't come from plants or natural sources. There isn't a lot of research on how it affects skin, so it's considered a cautious choice for people with sensitive skin.
