EGT Active Mechanism & Formulation Guide for Cosmetic Chemists
🧬 Mechanism & Efficacy Highlights (How EGT Works)
Mitochondrial Target (OCTN1 Substrate): Acts as a high-affinity substrate for the unique skin cell transporter OCTN1. This allows EGT to directly penetrate the mitochondria and cell nuclei, neutralizing ROS where aging begins.
Synergistic Anti-Photoaging: Inhibits UV-induced Matrix Metalloproteinases (MMPs) activation, effectively protecting the dermal collagen matrix from degradation.
🧪 EGT Formulation & Processing Guidelines (Stability & Compatibility)
Targeted Applications: High-end anti-aging serums, DNA-repair creams, eye contours, and premium longevity skincare lines.
Recommended Dosage: 0.01% – 0.5% (Highly effective at micro-dosages; up to 1.0% for professional shock treatments).
Solubility & Stability: 100% water-soluble. Highly stable under thermal processing up to 180°C and across a wide pH range (3.0 – 9.0).
System Compatibility: Excellent compatibility with standard thickening systems (including Carbomer and acrylic polymers) within recommended dosages; excellent synergy with Natural Ferulic Acid and Hyaluronic Acid.
Quality Assurance & Liability Exclusion Disclaimer: Every commercial batch matches the pre-shipment sample identically. We provide 100% traceable third-party lab reports (SGS/Eurofins). If independent third-party testing reveals any specification compliance failure upon arrival, PhytoVeris supports a 100% full refund policy and covers return logistics costs.
