Cinnamyl alcohol or styron[2] is an organic compound that is found in esterified form in storax, Balsam of Peru, and cinnamon leaves.

Cinnamyl alcohol occurs naturally only in small quantities, so its industrial demand is usually fulfilled by chemical synthesis starting from cinnamaldehyde.

[3] The compound is a solid at room temperature, forming colorless crystals that melt upon gentle heating.

Cinnamyl alcohol has a distinctive odor described as "sweet, balsam, hyacinth, spicy, green, powdery, cinnamic" and is used in perfumery[4] and as a deodorant.

[5] Cinnamyl alcohol has been found to have a sensitizing effect on some people[6][7] and as a result is the subject of a Restricted Standard issued by IFRA (International Fragrance Association).
