Science
Mechanism of Action
As a cosmetic colorant, CI 40825 functions by imparting a vibrant yellow-orange to red hue to formulations. Being a synthetic carotenoid, it theoretically holds potential antioxidant properties, aiming to neutralize harmful oxygen radicals. However, specific mechanisms of action relating to direct skin benefits beyond its coloring capability are not extensively documented in cosmetic science for this ingredient.

Stability
CI 40825 exhibits sensitivity to both oxygen and light, necessitating storage in light-resistant, tightly sealed containers, ideally under an inert gas and refrigerated, to maintain its integrity. Despite this, it demonstrates good stability against alkalis and acids, indicating robust performance across a range of pH conditions.
Safety
Safety Profile
CI 40825, also known as C.I. Food Orange 7 or Ethyl 8'-apo-β-carotenoate, is approved by the FDA as a food color additive with specific concentration limits (15 mg/lb in solid food, 15 mg/pt in liquid food). For cosmetic applications, however, no defined maximum concentration limits have been established, and comprehensive safety assessments by bodies such as CIR or SCCS are currently unavailable.
