CITRONELLAL

Description

Citronellal is a naturally occurring organic compound found in various essential oils, particularly citronella oil, which is derived from plants of the Cymbopogon genus. This monoterpenoid aldehyde possesses a distinct lemon-lime scent and is widely used in the fragrance and personal care industries. In skincare formulations, citronellal serves multiple purposes, including its role as a fragrance component and potential therapeutic benefits.

The compound exhibits antimicrobial and antifungal properties, making it valuable in products aimed at addressing skin infections or maintaining skin hygiene. Its pleasant aroma also contributes to the sensory experience of skincare products. Citronellal is known for its insect-repellent properties, which can be beneficial in outdoor-use skincare formulations.

However, citronellal can be a skin sensitizer for some individuals, potentially causing allergic reactions or irritation in higher concentrations. It's crucial to use this ingredient judiciously in skincare formulations, typically at concentrations below 1%. Patch testing is recommended for products containing citronellal, especially for those with sensitive skin or known allergies to fragrances. When used appropriately, citronellal can enhance both the functional and olfactory aspects of skincare products.
