Lutein Ester CAS ：547-17-1

First and foremost, we source Tagetes erecta (marigold) petals as the sole natural raw material for our Lutein Ester. We handpick fresh, pesticide-free marigold flowers from high-ecology planting bases to ensure a pure and safe ingredient foundation. In addition, we adopt low-temperature solvent extraction and spray drying technology to lock all active carotenoids without damage. This advanced process retains high levels of lutein, zeaxanthin, and other functional components.

Furthermore, our Lutein Ester presents an orange-to-brown fine powder with uniform particle size and excellent flowability. It features good solubility in organic solvents and stable physical properties under normal storage. Unlike low-quality synthetic alternatives, our product contains no artificial pigments, fillers, or harmful additives. For this reason, it gains wide recognition in the global dietary supplement and food additive markets.

Besides, this CAS 547-17-1 Lutein Ester delivers superior bioavailability compared to free lutein. It converts into active lutein in the human body more efficiently, which supports macular pigment density and filters harmful blue light. Many health brands use it as a core raw material for eye health supplements, multivitamins, and antioxidant formulas. It also works well in functional foods, beverages, and skincare products.

In particular, we provide customizable specifications including 5%–90% lutein content and different mesh sizes to meet diverse customer needs. We maintain sufficient stock all year round to support small trial orders and large bulk shipments. Meanwhile, we implement strict quality control from raw material testing to finished product inspection. Every batch complies with GMP, ISO, and food-grade standards.

Finally, we offer reliable global supply and professional technical support. We share detailed COA, MSDS, and application guidance for each client. We also arrange fast and safe international logistics to ensure on-time delivery. We always adhere to quality-first principles to build long-term partnerships with manufacturers and distributors worldwide.
