Product Overview

4-Butylresorcinol is a stable derivative of resorcinol and acts as a potent tyrosinase inhibitor due to its structural composition, which includes free hydroxyl groups in specific positions on its aromatic ring. This capability enables it to effectively impede one of the key enzymes involved in melanin synthesis, thereby reducing hyperpigmentation, blotches, and freckles. When utilized in skincare formulations, 4-Butylresorcinol has been shown to significantly diminish UV-induced pigmentation on the forearms. By preventing melanin production, it serves as a powerful skin-whitening agent, offering greater stability and effectiveness than traditional lightening ingredients. With its relatively small molecular size, 4-Butylresorcinol penetrates the deeper layers of the skin swiftly, promoting a uniform, brighter, and more radiant complexion. It is characterized by a light-beige color and is soluble in most organic solvents, although only slightly soluble in water. Additionally, 4-Butylresorcinol is safe and hypoallergenic, making it an ideal component in various dermatological applications.
