Hydroxycitronellal

Description

Hydroxycitronellal is a synthetic fragrance ingredient widely used in perfumery and personal care products. This colorless to pale yellow liquid compound belongs to the family of aldehydes and is characterized by its fresh, floral scent reminiscent of lily of the valley. Hydroxycitronellal has a molecular formula of C10H20O2 and is produced through the hydroxylation of citronellal, a naturally occurring terpene.

In skincare formulations, hydroxycitronellal serves primarily as a fragrance component, imparting a pleasant aroma to products. It is found in various cosmetics, including lotions, creams, and soaps. While not typically used for its skincare benefits, it contributes to the overall sensory experience of products.

It's important to note that hydroxycitronellal is a known allergen and must be declared on product labels in many jurisdictions when used above certain concentrations. Some individuals may experience skin irritation or allergic reactions upon exposure. As a result, formulators must carefully consider its inclusion and concentration in products, especially those intended for sensitive skin.

Hydroxycitronellal's stability in formulations and its ability to blend well with other fragrances make it a popular choice in the cosmetic industry, despite potential sensitivities.
