Used as a fragrance ingredient in perfumes, soaps, and cosmetics due to its fresh, citrus-like aroma. It provides stability to fragrance formulations, especially in products exposed to light or air, because the acetal group protects the aldehyde from oxidation. Commonly found in household cleaners and air fresheners to impart a lemon scent. Also serves as a masking agent in pharmaceuticals and personal care products to cover unpleasant odors. Its stability makes it suitable for use in laundry detergents and fabric softeners where long-lasting scent performance is desired. In addition, it is used in the food industry as a lemon flavoring agent in certain products, and is considered safe when used in specified amounts.
