Best 4-Butylresorcinol Skin Lightening Ingredient for Cosmetic Formulations Companies, Factory
Product Description
4-Butylresorcinol is a high-efficiency, mild cosmetic whitening active ingredient featuring superior melanin-inhibiting performance compared to conventional brightening agents. It effectively blocks tyrosinase activity, suppresses melanin synthesis, and fades chloasma, sun spots, and post-inflammatory hyperpigmentation while evening out skin tone.
This raw material features low irritation and excellent skin compatibility. It is widely formulated into whitening serums, spot essences, brightening facial creams, and toners, delivering long-lasting brightening efficacy without causing skin sensitization.
≥99% HPLC grade with low heavy metal impurities. Fully compliant with EU and US cosmetic regulations, supplied securely in 25kg drums.
Inhibits both tyrosinase and TRP-1 to halt melanin biosynthesis. Delivers superior whitening compared to arbutin and kojic acid at low concentrations (0.1%–2%).
Small lipophilic molecule structure allows easy penetration into the basal layer, suppressing melanin transfer to keratinocytes and clearing existing pigmentation.
Strong thermal stability. Synergizes effectively with Vitamin C, Tranexamic Acid, and Tetrahydrocurcumin across serums, lotions, and targeted spot creams.

We are a professional supplier of 4-Butylresorcinol. Our products strictly comply with international cosmetic raw material standards. Free samples are available for your testing and validation. Please feel free to reach out to us for further specifications, batch documentation, or quotation requests.
Our 4-Butylresorcinol is produced to an HPLC assay purity of ≥99% (typically reaching around 99.20%). It is supplied as a fine, pure white crystalline powder with low residual solvent and heavy metal values compliant with global standards.
The typical formulation dosage ranges between 0.1% and 2.0%. Because it acts as a potent dual-target inhibitor, low concentrations are capable of delivering visible depigmenting results.
Clinical research and chemical profiles demonstrate that 4-Butylresorcinol has a higher binding affinity to tyrosinase and TRP-1 enzymes. Its lipophilic structure enhances skin penetration, achieving significant dark spot fading with lower irritancy than kojic acid.
It demonstrates good thermal stability and lipophilic solubility. It pairs exceptionally well with other cosmetic actives such as Vitamin C derivatives, Tranexamic Acid, and Tetrahydrocurcumin without negative interactions.
Yes, complimentary samples are available for formulation testing and laboratory evaluation. Standard packaging for bulk orders is provided in sealed 1kg foil bags and 25kg standard fiber drums.
