Background

Hydroxycitronellal is a synthetic floral fragrance prepared by the hydration of citronellal and is not found in nature. It is an important ingredient in fragrances because of its sweet, lily-of-the-valley odor. The International Fragrance Research Association recommends that it not be used at a level more than 5% in fragrance compounds. It has also been approved by the U.S. FDA for use in foods.
