HEPES Supplier

Unlock the hidden potential of formulations with DropBrigt® HEPES (INCI: Hydroxyethylpiperazine Ethane Sulfonic Acid, CAS 7365-45-9)—a bio-compatible buffer that transcends pH control to deliver exfoliation, brightening, and UV-protective synergy. Backed by cutting-edge 3D skin models, here’s why this versatile active belongs in your next brightening or anti-aging formula. 🌟 Triple-Action Benefits Gentle Exfoliation Weak acid (pH 4.5–6.5) with macromolecular AHA-like properties. Softens keratinocytes, smooths texture, and boosts cell turnover without irritation at recommended doses (0.5–5%). Clinical Brightening Power Proven Synergy: In 3D melanin skin models, formulations with HEPES + tranexamic acid + AA2G + niacinamide (Composition A): ↑ L* value (brightness) by 15% vs. controls (P<0.01) ↓ Melanin content by 30% (P<0.01) Outperformed fewer-actives combos (B/C) in reducing UV-induced pigmentation. UV Absorption & Penetration Boost Absorbs UVA/visible light, offering secondary photoprotection. Enhances delivery of co-actives (e.g., vitamin C, niacinamide). 🔬 Science Spotlight: Brightening Synergy Test Parameter Composition A Composition B Composition C Tranexamic Acid 3% – – AA2G 1% 1% – Niacinamide 2% 5% 6% HEPES 0.5% 0.5% 0.5% Result vs. UV-Damaged Skin ↑ L* value 15%↓ Melanin 30% Moderate improvement Minimal impact Key Insight: HEPES amplifies brightening efficacy in multi-active systems—0.5% HEPES doubled melanin reduction vs. niacinamide-only formulas. ⚙️ Formulator-Friendly Profile Solubility: Water-soluble (1M solution: clear, colorless). Stability: Heat/light-stable; pH 4–8 compatible. Addition: Flexible—cold or hot process (≤80°C). Safety: Mild irritation (IS=4.77 at 2% in chicken embryo test).
