Hexylresorcinol

Product Description

Our high-purity Hexylresorcinol (4-hexylresorcinol) is manufactured under ISO-aligned controls with batch COA traceability, supplying cosmetic formulators direct factory pricing and flexible kilogram-to-tonne bulk volumes.

This alkylresorcinol brightener modulates tyrosinase activity, glutathione redox cycling, and NF-κB-linked melanogenesis signaling—delivering science-backed dark-spot and tone-evening claims at low use levels in serums, emulsions, and spot treatments.

Unlike hydroquinone or single-pathway arbutin systems, this CosIng-listed hexylresorcinol suits hydroquinone-free brightening portfolios where formulators want HPLC-verified assay, low-irritation profiles, and direct factory supply.

Key Benefits & Applications

Hexylresorcinol supports multi-pathway brightening, dark-spot, and tone-evening claims through low-dose alkylresorcinol activity suited to clinical-style brightening formulators.

• Tyrosinase Inhibition: Modulates tyrosinase-linked melanin synthesis in brightening serums and daily tone-evening essences.
• Dark Spot Correction: Targets localized hyperpigmentation in spot treatments, ampoules, and concentrated brightening gels.
• Whitening & Brightening: Supports overall radiance and tone-uniformity claims in clean-label brightening product lines.
• Anti-Inflammatory Modulation: Helps calm NF-κB-linked melanogenesis signaling in post-blemish and sensitive-skin brightening care.
• Antioxidant Protection: Resorcinol-derived activity scavenges oxidative stress in daytime brightening and UV-exposed formulas.
• Anti-Aging Defense: Supports photo-induced pigmentation defense in mature-skin brightening and correction emulsions.

Formulation Guidelines

Dissolve hexylresorcinol in the oil or hydroalcoholic phase; confirm assay, pH, and photostability before brightening claim validation.

• Recommended use level: 0.1–0.5% w/w in serums and emulsions; up to 0.5% in spot gels (Typical).
• Optimal formula pH: Maintain pH 4.0–7.0; best stability in mildly acidic to neutral systems (Typical).
• Processing: Pre-dissolve in propylene glycol or ethanol before adding to emulsion at 25–40°C.
• Compatibility: Works with niacinamide and alpha arbutin; separate strong oxidizers until cool-down when possible.
• Caution: May cause mild irritation at upper use levels—patch-test sensitive-skin and leave-on facial formulas.
• Synergy: Pair Niacinamide at 2–5% with hexylresorcinol in multi-pathway brightening serums for dual tyrosinase and transfer control.
