The active ingredient nCitronela Plus is composed of natural ingredients with insect repellent properties. Citronella essential oil (Cymbopogon winterianus) is one of the most commonly used natural repellents. The nanoencapsulation of essential oils enhances the stability of active compounds due to its ability to reduce volatilization and potential oxidation reactions. Furthermore, nanoencapsulation improves water solubility, enhances effectiveness, and prolongs the desired effect.
