Science
Mechanism of Action
This ingredient conditions the skin by leveraging its natural Alpha Hydroxy Acids (AHAs), which provide a gentle peeling effect to support skin renewal and promote a smoother complexion. Its unique polysaccharide and amino acid complex contributes to the skin's natural moisturizing factors, enhancing hydration. Additionally, compounds within orange peel extracts exhibit potent antioxidant and antimicrobial capacities, aiding in skin protection and purification. It also acts as an absorbent and helps stabilize emulsions.

Stability
The extract derived from Citrus Aurantium Dulcis Peel is thermally stable, allowing its incorporation into the water phase at temperatures between 70-75°C prior to emulsification. Low temperatures may induce cloudiness, yet this effect is reversible above 15°C and does not compromise the ingredient's activity or integrity.
Conflicts
- Formulations containing high concentrations of furocoumarins, particularly above 0.0015% (15 ppm) 5-methoxypsoralen (5-MOP) in leave-on products, should be avoided due to phototoxicity risks.
- Application on broken or irritated skin is contraindicated.
- Strongly alkaline environments are unsuitable, as citrus extracts perform optimally in slightly acidic conditions.
- Daytime formulations must meticulously account for potential photosensitivity, necessitating robust sun protection.
- Combining multiple botanical ingredients that could collectively elevate levels of sensitizing constituents like limonene, citral, or furocoumarins requires careful evaluation.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Panel deemed citrus peel-derived ingredients, including Citrus Aurantium Dulcis Peel Powder, safe for cosmetic use when formulated to be non-sensitizing and non-irritating. For leave-on products, the concentration of 5-methoxypsoralen (5-MOP) must not exceed 0.0015% (15 ppm). The Scientific Committee on Consumer Safety (SCCS) advises that furocoumarin content in sun-protection and bronzing products should be maintained below 1 mg/kg. Undiluted sweet orange peel has been associated with phototoxic reactions in individuals with Type I skin, and the ingredient possesses the potential to cause irritation or allergic reactions in sensitive individuals. The highest reported maximum concentration of use is 6% in rinse-off skin cleansing preparations.
