Uses

edit

The most common use is as a food additive to add flavor.[5][6] The material also has insect repellent properties.[7]

Manufacture

edit

Hydrogenation of cuminal can produce cumyl alcohol.[8]

Other

edit

Cumyl alcohol is an undesired side reaction product when LDPE is crosslinked.[9] LDPE is used as a plastic electric insulator for electrical power cables.[10] The cumyl alcohol reduces the insulating properties.[11][12]
