Methoxypropylamino Cyclohexenylidene Ethoxyethylcyanoacetate (trade name Aurafix or RonaCare AP) is a soluble, lipophilic filter designed to absorb high-energy visible (HEV/blue) light, often added to sunscreens and antioxidant formulations to extend protection beyond UV. It complements traditional UV filters and is used in anti-pollution and anti-aging products.
