4-Butylresorcinol
What is 4-Butylresorcinol?
4-Butylresorcinol is a synthetic organic compound derived from resorcinol, featuring a four-carbon butyl chain attached to its phenolic structure. Produced through chemical synthesis, it belongs to the alkylresorcinol family commonly incorporated into skincare formulations like serums, creams, and lotions targeting skin appearance. In products, it functions primarily by inhibiting tyrosinase, an enzyme key to melanin synthesis, while also providing antioxidant effects to neutralize free radicals from environmental stressors. This dual action helps maintain product stability and contributes to skin's oxidative defense. Typically used at low concentrations, it appears in brightening and anti-aging cosmetics, offering a resorcinol-based alternative valued for its potency in lab studies on pigmentation pathways.
