3,5,5-TRIMETHYL-2-CYCLOHEXEN-1-OL

Chemical Properties

clear colorless liquid

Uses

This alcohol has found a little use in perfume compositions, mainly in Honey-bases as a modifier and powerful ingredient. It blends excellently with Phenylacetic acid and its esters, with Mimosa, Labdanum and the conventional Acetophenone-derivatives, and it is, incidentally, very interesting in YlangYlang.
