Zeaxanthin 10% HPLC (Marigold Extract)

Product Description

Zeaxanthin 10% (Marigold Extract) is a high-quality natural carotenoid raw material. In the macular region of the human eye, zeaxanthin works synergistically with lutein to form the core defense barrier that absorbs harmful high-energy blue light and quenches free radicals. Zeaxanthin is predominantly concentrated in the central region of the macula, helping to mitigate oxidative stress damage caused by intense light and blue light emitted by screens.

Our Zeaxanthin 10% raw material is derived from premium marigold flowers (Tagetes erecta L.). Through refined purification and rigorous High-Performance Liquid Chromatography (HPLC) assay testing, we guarantee a stable active zeaxanthin content of ≥ 10.0%. The product appears as a fine, uniform orange-red powder that 100% passes through an 80-mesh sieve. It offers exceptional dry-blend dispersibility and filling adaptability, empowering dietary supplement and functional food brands to seamlessly develop highly competitive eye health formulations.

Key Features & Highlights

• Standardized Active Ingredient: Verified by authoritative HPLC assay to guarantee active zeaxanthin content ≥ 10.0%, delivering excellent batch-to-batch consistency for precise formulation dosing.

• Pure Marigold Origin: 100% sourced from premium marigold flowers with zero artificial additives, meeting consumer demands for Clean Label and natural nutrients.

• Superior Solid Oral Dosage Processing: 100% passes through 80 mesh with uniform particle distribution and good flowability, effectively preventing component stratification and tableting sticking during dry blending.

• Ultra-Low Solvent & Pesticide Risk: Strictly controlled residual hexane and ethanol levels, with pesticide residues (666, DDT, Quintozine) and heavy metals maintained well below international regulatory limits.

• Long-Term Ultra-Stability: Vacuum-sealed in inner aluminum foil bags, boasting a 24-month shelf life when stored away from light and heat, significantly reducing supply chain storage and degradation risks.

Formulator's Guide & Processing Advantages

• Uniform Pre-blending & Dispersion: Thanks to its 80-mesh fine particle size (100% pass rate) and optimal bulk density (0.4–0.7 g/ml), Zeaxanthin 10% achieves rapid and highly uniform dispersion when dry-blended with excipients like microcrystalline cellulose, magnesium stearate, or starch, making it perfect for high-speed tableting and capsule filling.

• Protection Against Light & Thermal Sensitivity: As a carotenoid, zeaxanthin is sensitive to intense light, high temperatures, and oxygen. It is recommended to control processing temperatures and use light-barrier aluminum foil or dark containers for finished packaging. Combining it with antioxidants like Vitamin C or Vitamin E can further extend shelf life.

• Formulation Application Tip: This product is a dry powder physically processed from oil-soluble natural ingredients and forms a suspension in aqueous systems. For clear beverage formulations, a water-soluble/water-dispersible (WS) grade is recommended.

Applications

• Synergistic Golden Ratio Eye Health Capsules/Tablets: Co-formulated with Lutein at classic ratios of 5:1 or 10:2 to construct a comprehensive anti-photodamage defense shield across the entire retinal macular area.

• Protective Products for Heavy Screen Users: Formulated for developers, esports players, and office workers to reduce eye fatigue, dryness, and visual blur caused by shortwave blue light.

• Preventive Formulas for Age-Related Macular Degeneration (AMD): Combined with Bilberry Extract, Grape Seed Extract, and natural Zinc/Selenium to protect against age-related visual decline and enhance contrast sensitivity.

• Functional Nutritional Foods & Solid Beverages: Suitable for dry-blended meal replacement powders, protein powders, chewable tablets, and energy bars, adding a natural orange-yellow tint and health appeal.

• Oral Anti-Aging & Skin Photoprotection: Leverages its potent carotenoid free-radical quenching capability in combination with collagen peptides and astaxanthin for oral anti-photoaging and post-sun skin recovery products.
  
  

Quality Assurance & Global Compliance

• Strict Solvent & Pesticide Controls: Every batch undergoes Gas Chromatography (GC) testing for hexane and ethanol residuals, as well as organochlorine pesticides (666, DDT, Quintozine), fully meeting stringent European and American food and supplement safety regulations.

• Heavy Metal & Microbiological Regulation: Accurately quantified via Atomic Absorption Spectrometry (AAS) for heavy metals (lead, arsenic, cadmium, mercury). CP2010 standards ensure Total Plate Count ≤ 1000 cfu/g with non-detectable pathogens.

• Standard Vacuum Aluminum Foil Packaging: Sealed internally with 1kg or 5kg double-layer vacuum aluminum foil bags and packaged externally in 25kg standard fiber drums, providing effective moisture, oxygen, and light barrier protection for long-distance ocean shipping.

FAQ

Q1: What is the water solubility of Zeaxanthin 10% powder? Can it be used directly in liquid beverages?

A1: Zeaxanthin 10% is a dry powder form physically processed from oil-soluble components and disperses as a suspension in water. To develop clear, transparent liquid beverages, we recommend choosing our water-dispersible (WS) or microencapsulated zeaxanthin grades.

Q2: What is the ideal synergistic ratio between Zeaxanthin and Lutein?

A2: Based on clinical research (such as AREDS2), the natural ratio in the human macular region is typically 5:1 (Lutein:Zeaxanthin). You can formulate our Zeaxanthin 10% raw material with Lutein at this precise ratio.

Q3: Why choose an 80-mesh particle size? What are the benefits for tableting or capsule filling?

A3: An 80-mesh size (100% pass rate) is the sweet spot for solid oral dosage manufacturing. It ensures uniform dry blending with excipients like microcrystalline cellulose while avoiding excessive dust that could cause tablet sticking or weight variation in capsules.

Q4: Does your Zeaxanthin comply with pesticide and heavy metal limits in North America and Europe?

A4: Absolutely. Every batch is rigorously tested for organochlorine pesticides (666, DDT, Quintozine) and heavy metals (lead, arsenic, cadmium, mercury), maintaining levels far below USP and European Pharmacopoeia (EP) monograph limits.

Q5: How do I ensure the stability and active potency of Zeaxanthin during manufacturing and storage?

A5: Zeaxanthin is sensitive to light and heat. We ship it vacuum-sealed in light-blocking aluminum foil bags. We recommend storing the material in a cool, dry, and dark environment and utilizing light-barrier packaging for finished products.

Q6: Can you provide free samples for HPLC testing? What is your Minimum Order Quantity (MOQ)?

A6: Yes, Keep Ingredients offers complimentary 50g–100g samples for HPLC assay verification and stability testing. We support flexible low MOQs for commercial orders to help minimize your R&D investment.
