Phenyl T-Butylnitrone (Spin Trap)
What is Phenyl T-Butylnitrone (Spin Trap)?
Phenyl T-Butylnitrone, also called Spin Trap or PBN, is a synthetic organic compound belonging to the nitrone class. It features a phenyl group attached to a tert-butylnitrone structure, designed specifically for its ability to detect and trap unstable free radicals. In cosmetics, it serves primarily as an antioxidant in formulations like serums, creams, and anti-aging products. Its function involves reacting with reactive oxygen species (ROS) to form stable adducts, thereby interrupting chain reactions that could lead to oxidative stress on skin lipids, proteins, and other components. This mechanism helps preserve the integrity of both skin barriers and product efficacy during storage and application. Derived through chemical synthesis, it is incorporated at trace levels to support overall formulation stability without altering texture or sensory attributes.
