BeriCos® W-47 (4-Butylresorcinol) | Your Trusted Whitening Active Partner

 Introducing BeriCos® W-47, our high-performance 4-Butylresorcinol—an industry-leading whitening cosmetic active renowned for exceptional stability, backed by our own source factory and cutting-edge R&D strength. As a core ingredient for premium skincare formulations, it solves the common pain points of traditional 4-Butylresorcinol (poor stability, easy oxidation, formulation difficulties) and has become the first choice for global skincare brands pursuing efficacy and reliability.

🔬 Leading R&D Strength, Breaking Stability Barriers  

    Our professional R&D team, composed of senior chemists and cosmetic ingredient experts, focuses on the structural optimization and stability enhancement of 4-Butylresorcinol. Equipped with a state-of-the-art laboratory and advanced testing equipment (HPLC, GC-MS, stability chambers), we have developed exclusive purification and modification technology to optimize the molecular structure of BeriCos® W-47. This breakthrough effectively resists oxidation, light, and temperature changes—solving the problem of discoloration and efficacy loss that plagues traditional 4-Butylresorcinol, while maintaining its powerful tyrosinase inhibition ability, which is 20 times stronger than kojic acid and 500 times stronger than arbutin.

🏭 Source Factory, Strict Quality & Stable Supply  

    As a professional source manufacturer, we own a standardized GMP-compliant production base with integrated intelligent production lines and full-process quality control systems. From raw material selection to finished product packaging, every link is strictly supervised to ensure consistent quality and ultra-low batch variation. With mature mass production technology and an annual capacity of 300 tons, we can flexibly meet both small-batch trial orders and large-scale bulk procurement needs, providing on-time and stable supply for global customers, and eliminating middlemen to ensure cost advantages and quality traceability.

✨ Exceptional Stability, Formulator-Friendly  

    BeriCos® W-47 boasts unparalleled stability: it remains stable under normal storage conditions for 36 months, without discoloration or efficacy attenuation even when exposed to light and high temperature (up to 180°C). It is amphipathic, easily soluble in both water and oil phases, compatible with serums, creams, toners, and masks, and can be seamlessly compounded with niacinamide, vitamin C derivatives, and peptides—greatly reducing formulation difficulty and improving production efficiency.
