Product Description
Lutein ester is a kind of important carotenoids fatty acid ester, dark brown tiny particles.
Most exists in the nature of the lutein esters can be divided into trans lutein esters and lutein esters, basically give priority to with all trans configurations.
AI Product Description
*The following content is generated by AI and is for reference only.
Lutein ester is a vital lipid-soluble carotenoid derivative widely utilized in the nutraceutical, food, and cosmetic industries. Chemically, it is formed by the esterification of lutein with fatty acids, most commonly palmitic acid, which significantly enhances its stability and bioavailability compared to free lutein. The primary molecular formula for lutein dipalmitate, the most prevalent commercial form, is C56H90O4. Its corresponding CAS number is 23780-12-9, though specific esters may vary slightly depending on the acyl chain length. This compound serves as a powerful antioxidant, protecting cells from oxidative stress caused by free radicals and ultraviolet radiation.
In the dietary supplement sector, lutein ester is extensively incorporated into softgels and capsules to support ocular health. It accumulates in the macula of the human eye, filtering harmful blue light and reducing the risk of age-related macular degeneration (AMD) and cataracts. Due to its superior thermal and oxidative stability, manufacturers prefer the esterified form over free lutein during processing, ensuring the active ingredient remains intact through high-temperature manufacturing processes like extrusion or baking. Consequently, it is a key functional ingredient in fortified foods, including beverages, dairy products, and baked goods.
Beyond nutrition, lutein ester finds applications in cosmetics for its photoprotective properties, helping to shield skin against UV-induced damage and premature aging. The esterification process also improves solubility in oil-based formulations, facilitating easier integration into creams and serums. Regulatory bodies globally recognize lutein ester as safe for consumption within established limits, making it a versatile and trusted additive. As consumer awareness regarding eye care and skin protection grows, the demand for high-quality lutein ester continues to rise, driving innovation in delivery systems to maximize absorption and efficacy. Its role in maintaining long-term visual and dermal health underscores its importance in modern wellness strategies.
