Citrus Aurantium Amara (bitter orange) Flower Water, also known as neroli or orange blossom water, is a hydrosol obtained from steam distillation of bitter orange blossoms. It is used in skincare primarily as a fragrant, mildly soothing and toning aqueous base ingredient.
| Reported effect | How often | Notes |
|---|---|---|
Contact allergy / sensitization | Uncommon | May occur due to naturally occurring fragrance components such as limonene and linalool. |
Skin irritation (redness, stinging) | Uncommon | More likely on sensitive or compromised skin. |
Phototoxicity | Rare | Citrus-derived materials can contain furocoumarins; properly distilled flower waters generally have minimal levels, but residual photosensitizing potential is noted. |
Allergic contact dermatitis | Rare | Reported in fragrance-sensitive individuals on patch testing. |
