Citrus Aurantium Amara (Bitter Orange) Peel Oil

CIT

6/10

Concern level

Moderate concern

A cold-pressed or expressed citrus peel essential oil used primarily as a fragrance ingredient. It is a complex natural mixture dominated by volatile terpenes such as limonene rather than a single defined molecule, so molecular weight and pH are not applicable. CIR lists citrus-derived peel oils, including bitter orange peel oil, as safe for cosmetic use with qualifications, and PubChem identifies it as a fragrance ingredient.

Interactions

incompatible with: other essential oils and fragrance allergens due to cumulative sensitization risk, strong oxidizing agents that can accelerate terpene oxidation, leave-on formulas with other photosensitizing citrus oils or furocoumarin-containing extracts

Risks & Warnings

Can cause skin and eye irritation, allergic sensitization, and oxidation-related fragrance allergy risk; citrus peel oils may also be phototoxic if they contain furocoumarins such as 5-MOP above recommended limits. Avoid on compromised or very sensitive skin and minimize sun exposure if used in leave-on products.
