Isorhamnetin

Product Description

Isorhamnetin is a high-performance, multi-functional flavonoid, representing the next wave of potent, plant-derived actives. This powerful molecule provides a comprehensive defense against the primary factors of premature aging. Its key advantage is its triple-action efficacy: it delivers robust antioxidant protection against environmental stressors, potently soothes inflammation and redness, and helps to promote a brighter, more even-toned complexion. For formulators seeking a single, science-backed ingredient to address the complex needs of stressed, dull, or aging skin, Isorhamnetin is a sophisticated and highly effective choice.

Product Uses

This powerful active ingredient is a cornerstone for high-end, science-driven skincare:

• Protective Skincare: Ideal for "anti-pollution" and "urban defense" serums and day creams to shield the skin from free radical damage.
• Soothing Formulations: A key component in products for sensitive or irritated skin to calm redness and reduce inflammation.
• Brightening Products: Used in brightening serums and spot treatments to help correct hyperpigmentation and improve overall skin radiance.
• Anti-Aging: Incorporated into anti-aging lines to protect against photoaging and support skin health.

Formulation Suggestions

The recommended dosage is between 0.1-1.0%. As an oil-soluble powder, Isorhamnetin should be pre-dissolved in a suitable solvent system (e.g., a blend of glycols and ethanol) before being added to a formulation. It is best incorporated into the oil phase of an emulsion or into anhydrous systems. To ensure stability and prevent potential color shifts, the final formulation's pH should be maintained in the slightly acidic to neutral range (pH 5.0-6.5), and opaque or UV-protective packaging is recommended.

Our advice is for reference only. Please follow the recommendations of your formulator for actual production.
