Nerolioil

The essential nerolioil, also known as bitter orange blossom oil or orange blossom oil, is obtained from the freshly picked blossoms of the bitter orange tree(bitter orange plant) by steam distillation. The by-products of distillation are orange blossom water and absolute.

Phytotherapeutic use - as aromatherapy to reduce pain and anxiety (Scandurra C et al. 2022), alleviation of menopausal symptoms, including lowering blood pressure, stress reduction (Choi SY et al. 2o14).

Neroli oil has a calming, relaxing and mood-enhancing effect. It also has an antiseptic (also antifungal), antispasmodic and digestive effect.

The production of neroli is complex; 1 kg of yellowish essential oil can be extracted from 1000 kg of white flowers.
In cosmetics, neroli is used to care for mature skin. It has a firming effect on the skin.

Nerolioil mainly contains terpenes (over 90 %), above all limonene; also linalyl acetate, neryl acetate, geraniol, citronellol and nerol. Small amounts of linalool and terpineol are also present.

bitter orange oil can cause contact sensitization and photoallergic reactions. The DKG has previously tested 2% bitter orange oil in Vaseline (see below fragrances and essential oils). This test application is no longer available. In this respect, a 5% test solution is now recommended (as of 2016).
