Product Description
Product Description of Arbutin CAS#497-76-7
Arbutin is a glycosylated form of hydroquinone naturally found in Arctostaphylos plants and exhibits a range of biological activities, including tyrosinase inhibition, antioxidant effects, and anti-inflammatory properties. It effectively suppresses human tyrosinase activity in crude enzyme preparations isolated from melanocytes (IC50 values of 5.7 and 18.9 mM using L-tyrosine and L-DOPA as substrates, respectively) as well as in intact melanocytes (IC50 = 0.5 mM).
At a concentration of 50 μM, arbutin inhibits hemolysis induced by the free radical generator AAPH in sheep erythrocytes, and at concentrations above 125 μM, it prevents AAPH-induced reductions in cell viability in cultured human skin fibroblasts. In an LPS-induced rat model of acute lung injury, arbutin (50 mg/kg) suppresses increases in IL-1β, IL-6, and TNF-α levels in both lung tissue and serum. Formulations containing arbutin have been widely applied in the treatment of hyperpigmentation disorders.
Product Application of Arbutin CAS#497-76-7
Arbutin is applied in diuretic and anti-infective medications for the urinary system. It is also used as a stabilizer in color photographic developing processes. In cosmetic formulations, arbutin is widely utilized for skin whitening, freckle reduction, and hair care applications.

FAQ
Q1: Is Huafeng Chemical a manufacturer or a trader?
A: We are a professional service provider specializing in chemical foreign trade. Rather than being limited to the products of a single factory, we leverage the chemical industry cluster in Shandong Province to integrate production resources from multiple high-quality manufacturers. This allows us to offer a wide range of sourcing options—covering various product categories and origins—instead of simply pushing a single product. Furthermore, our core competitiveness lies in our professional foreign trade services (covering documentation, logistics, and regulatory compliance), ensuring a smooth and worry-free procurement process for you.
Q2: How is the security of my transaction guaranteed when working with Huafeng Chemical?
A: We strictly adhere to international trade rules (Incoterms® 2020) and accept various payment methods, such as Letters of Credit (L/C) and Telegraphic Transfers (T/T). For new clients, we support small-batch trial orders and can clearly define arbitration clauses and applicable laws within the contract. Additionally, we maintain a robust risk management system to help you mitigate common trade risks, such as exchange rate fluctuations, shipping delays, and document discrepancies.
Q3: Do you have experience serving clients in Russian-speaking regions?
A: Yes. We place great importance on the Russian-speaking market; our team includes Russian-speaking business professionals who are well-versed in the import regulations of Russia and the Eurasian Economic Union (EAEU). We understand the importance of EAC certification to clients in these regions and can assist with related compliance inquiries. We have established connections with chemical traders across various CIS countries and have gained valuable experience in specialized packaging and temperature-controlled shipping designed to withstand harsh local winter conditions.
Q4: How do you guarantee product quality?
A: We implement a strict supplier qualification and periodic audit system. A Certificate of Analysis (COA)—issued by the original manufacturer—is provided with every shipment. We also welcome pre-shipment inspections conducted by internationally recognized third-party agencies such as SGS, BV, or ITS. Should the test results fail to meet the standards specified in the contract, you have the right to reject the goods or request a replacement.
