4-Butylresorcinol is a highly effective, gentle active ingredient used in cosmetic skin-lightening formulations. It works by directly inhibiting the activity of tyrosinase and peroxidase—two key enzymes responsible for melanin synthesis—thereby fading dark spots and evening out overall skin tone.
Our 4-Butylresorcinol has a high purity specification of ≥99% (with actual batch test results showing 99.20%), ensuring maximum efficacy and stability when formulated into cosmetic products.
It is widely compatible and commonly formulated into skin-brightening serums, targeted spot-correcting essences, facial creams, and daily toners.
No, compared to traditional brightening agents, 4-Butylresorcinol features low skin irritation and excellent compatibility, delivering stable and long-lasting brightening benefits without causing sensitization.
For quantities of 1kg, we package using double plastic bags inside with an aluminum foil bag and an outer box. For bulk quantities of 10kg, 25kg, or more, we package using high-quality drums or cartons with double-layered plastic bags inside to maintain optimal stability.
We support multiple delivery channels depending on weight. Small orders (1kg-25kgs) are shipped door-to-door via express services like DHL, FedEx, UPS, or EMS within 3-7 days. Larger orders can be shipped via Air (3-7 days) or Sea (10-35 days) to suit your logistical requirements.
