How is it used?

Hydroxycitronellal is used as a fragrance ingredient and fragrance enhancer in many cosmetic products*. It can be found naturally in some plants such as lavender but in most consumer products where you can find it, is synthetically produced. Hydroxycitronellal is synthetically produced from the naturally occurring fragrance chemical citronellal (not to be confused with citronellol). The chemical has a sweet floral odor and is most commonly found in perfumes, colognes and fragrances. But It is also found in hair products, skin care products and oral products.

“Cosmetics range from everyday hygiene products such as soap, shampoo, deodorant, and toothpaste to luxury beauty items including perfumes and makeup”.
