Isoquercitrin

Product Description

Our Isoquercitrin is manufactured in our specialized extraction facility, ensuring a consistent direct factory supply of high-purity material for the global cosmetic market. Scientifically, it functions as a powerful bioflavonoid that effectively neutralizes reactive oxygen species (ROS) and inhibits lipid peroxidation to protect dermal cells from oxidative stress. As a more bioavailable and water-soluble derivative of quercetin, it represents a premium commercial solution for formulators seeking stable, high-efficacy antioxidants in advanced anti-aging and skin-repair systems.

Key Benefits & Applications

• Potent ROS Scavenging: Demonstrates high efficiency in reducing oxidative stress by neutralizing free radicals, thereby preventing premature dermal aging.
• Anti-Glycation Activity: Helps inhibit the formation of Advanced Glycation End-products (AGEs), preserving the structural integrity of collagen and elastin fibers.
• Dermal Soothing: Effectively modulates inflammatory pathways to provide localized soothing and reduce skin redness caused by environmental stressors.
• UV-Induced Damage Mitigation: Enhances the skin's natural defense mechanisms against UV-induced photodamage when integrated into daytime protection formulas.

Formulation Guidelines

• Suggested Dosage: 0.05% – 0.5% (Formulators should conduct safety assessments according to the "Technical Guidelines for Cosmetic Safety Assessment")[cite: 2].
• pH Stability: Optimal stability is maintained in formulations with a pH range of 4.5 to 6.5.
• Processing: Due to its improved solubility, it can be pre-dissolved in the aqueous phase or added during the final stage of formulation below 40°C.
• Storage: Store in a cool, dry place away from direct sunlight to prevent oxidation of the flavonoid structure.
• Synergy: Combine with L-Ascorbic Acid for enhanced network antioxidant protection and stabilized skin brightening effects.
