CITRUS AURANTIUM AMARA FRUIT EXTRACT.

Given that the maximum reported use concentration for CITRUS AURANTIUM AMARA FRUIT EXTRACT in cosmetic products is 0.002%, it falls within a range often associated with 'dusting' – where an ingredient is included at levels too low to exert its purported primary benefits effectively. While it possesses inherent bioactive compounds, specific efficacy thresholds are not defined, indicating its presence might sometimes be for minor conditioning or aromatic purposes rather than significant therapeutic action at these low levels.

The Cosmetic Ingredient Review (CIR) Expert Panel has deemed this extract safe for use in both rinse-off and leave-on cosmetic products, provided formulations are non-sensitizing and non-irritating. A critical restriction for leave-on products mandates that the concentration of 5-methoxypsoralen (5-MOP), a specific furanocoumarin present in the extract, must not exceed 0.0015% (15 ppm). The highest reported use concentration for the extract itself is 0.002% in specific applications like lipstick and eye makeup. It is important to note that sensitive individuals may experience skin irritation or allergic reactions, and excessive use can lead to photosensitivity, thereby increasing sunburn risk. A preliminary patch test is highly advised, and application on broken or irritated skin should be avoided.
