Astaxanthin

Product Description

Astaxanthin is a high-purity, super-potent keto-carotenoid, celebrated as the "King of Antioxidants." Derived from *Haematococcus pluvialis* microalgae, its unique molecular structure allows it to span the entire cell membrane, providing comprehensive protection from both internal and external oxidative stress. Its key advantage is its unparalleled ability to neutralize singlet oxygen and protect skin cells from UV-induced photo-damage, making it the ultimate active for preventing premature aging. For formulators developing high-performance anti-aging and sun-care products, Astaxanthin is the definitive, science-backed ingredient for superior defense.

Product Uses

This premier antioxidant is the cornerstone for high-performance protective and anti-aging skincare:

• Anti-Aging: The ideal hero ingredient for advanced serums, night creams, and eye creams targeting wrinkles, loss of elasticity, and photodamage.
• Sun Care & After-Sun: A key component in sunscreens and after-sun lotions to provide robust protection against UV-induced free radicals and to calm inflammation.
• Protective Skincare: Used in "city defense" and "anti-pollution" formulas to shield skin from environmental stressors.

Formulation Suggestions

The recommended dosage is between 0.01-0.1%. As a high-purity, oil-soluble powder, Astaxanthin must be pre-dissolved in the oil phase, often with gentle heating (40-50°C) and stirring until no crystals remain. **Formulation Alert:** This ingredient is extremely sensitive to light and oxidation. It will impart a noticeable pink-to-orange hue to the final product. To ensure stability, the formula must include a robust antioxidant system (e.g., Vitamin E and Vitamin C derivatives) and a chelating agent. **Opaque, airless packaging is mandatory** to protect the active from degradation.

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