Hydroxycitronellal is commonly used to reproduce the scent of lily-of-the-valley in products such as perfumes, cleaners and detergents.

Hydroxycitronellal is irritating to the skin in high concentrations and thus has been restricted by the International Fragrance Association to a concentration of 1% or less in products such as perfumes.
