Safety

Safety Profile

CIR Status
Safe with restrictions
Max tested
0.0015%
Sensitization risk High

The Cosmetic Ingredient Review (CIR) Expert Panel has determined that citrus peel-derived ingredients are safe for cosmetic use, provided formulations are non-sensitizing and non-irritating. For leave-on products, the concentration of 5-methoxypsoralen (5-MOP) must not exceed 0.0015% (15 ppm). This ingredient is known to increase photosensitivity and is not recommended for sensitive skin due to potential irritation. The FDA has recognized some citrus peels as GRAS for food substances, but specific cosmetic restrictions apply.
