Essential oils are sensitive to UV rays. That's why it is advised to store them away from heat, light, humidity, in an amber glass bottle, and if necessary avoid too big temperature differences.
The essential oil of rosemary is generally well tolerated by the skin. However, be sure to dilute it to avoid any risk of irritation. Because of the presence of camphor and eucalyptol, it is not recommended for pregnant and breastfeeding women, young children and people suffering from epilepsy. It is also contra-indicated to the asthmatic subjects, especially in inhalation or diffusion. Avoid contact with the eyes.
Some natural compounds contained in this essential oil such as limonene and linalool may present a risk of allergy for some sensitive people, when the essential oil is incorporated into a cosmetic composition (according to the 7th Amendment of the European Directive on cosmetic products (2003/15/EC)). Thus, before any use, always make a test by applying the preparation in the fold of the elbow at least 48 hours before using it.
