U parfemima
OTNE is a synthetic woody odorant used as a fragrance ingredient in perfumes, laundry products and cosmetics. Beginning in the late 1980s, Iso E Super, another trade name of OTNE, became a staple in perfumery and was used in increasingly high amounts. It became part of Sophia Grojsman's accord of 20 percent each methyl ionone, Hedione, Iso E Super and Galaxolide. Iso E Super is in a wide variety of commercial products with differing scents.
