Pentaerythrityl Tetra‑Di‑T‑Butyl Hydroxyhydrocinnamate

Product Description

Our high-purity Pentaerythrityl Tetra-Di-T-Butyl Hydroxyhydrocinnamate (PTTHHC) is manufactured under ISO-aligned controls with batch COA traceability, supplying cosmetic formulators direct factory pricing and flexible kilogram-to-tonne bulk volumes.

This hindered phenolic ester scavenges free radicals in lipophilic phases—stabilizing unsaturated oils, retinoids, and fragrance components while delivering skin-facing antioxidant activity suited to anti-aging emulsions, oil serums, and sun-care oil phases.

Unlike BHT or single-chain phenolics with formulation odor concerns, this CosIng-listed PTTHHC suits clean-label oil-phase stabilization where formulators want HPLC-verified assay, heat-stable antioxidant performance, and direct factory supply.

Key Benefits & Applications

PTTHHC supports lipophilic antioxidant, formula-stabilizing, and anti-aging claims through hindered phenolic ester activity suited to oil-serum and emulsion formulators.

• Antioxidant Protection: Hindered phenolic ester scavenges radicals in lipophilic serums, creams, and sun-care oil phases.
• Free Radical Scavenging: Neutralizes lipid-phase free radicals to help protect unsaturated oils and sensitive actives from oxidation.
• ROS Inhibition: Suppresses reactive oxygen species formation in emulsion systems exposed to heat and light during storage.
• Anti-Aging Defense: Supports oxidative-stress defense narratives in mature-skin oil serums and anti-aging emulsions.
• Photo-Aging Protection: Helps defend lipids and actives against UV-accelerated peroxidation in daytime care formulas.
• Environmental Oxidative Defense: Stabilizes formulas and skin-facing lipids against pollution-linked oxidative stress in urban day-care lines.

Formulation Guidelines

Incorporate PTTHHC in the oil or silicone phase; confirm assay and compatibility with retinoids and fragrances before stability testing.

• Recommended use level: 0.05–0.5% w/w as formula antioxidant; up to 1% in oil-rich systems (Typical).
• Optimal formula pH: Effective across pH 3–9 when dissolved in oil phase before emulsification (Typical).
• Processing: Add to oil phase at 25–60°C; pre-dissolve in carrier oil for even dispersion in emulsions.
• Compatibility: Stabilizes retinyl palmitate, tocopherol, and unsaturated botanical oils; avoid uncontrolled strong oxidizers.
• Caution: Primary function is oil-phase stabilization—water-phase-only systems require co-solubilization or alternate antioxidants.
• Synergy: Retinyl Palmitate stays photostable longer when co-loaded with PTTHHC in lipophilic night creams at 0.05–0.3%.
