Application Track 1: Premium Dietary Supplements & Softgel Encapsulation

Designed specifically for encapsulation lines. Our oleoresin features superb physical flowability, high lipid-phase clarity, and optimal compatibility with soft gelatin or vegetarian starch shells.

R&D Directives: Utilize **AST-OL-10N** to minimize softgel size while maintaining high therapeutic potency, blending seamlessly with Lecithin or Coenzyme Q10 for synergistic benefits.

Application Track 2: Luxury Cosmetics, Anti-Aging Serums & Skincare

Leverages molecular distillation to clear natural microalgae odor. It offers a rich red hue that enhances formulation aesthetics while functioning as an ultra-powerful topical antioxidant.

R&D Directives: Incorporate **AST-OL-COS** into the oil phase at 0.05% - 0.2% concentration under nitrogen blanketing to ensure long-term color and active ingredient integrity.

Application Track 3: Functional Food Oils & Liquid Supplements

Allows clean-label branding as a botanical phytonutrient oil. Standardized with organic lipid carriers to ensure seamless miscibility with edible oils and liquid nutritional formulations.

R&D Directives: Suitable for daily nutritional droplet bottles, health-focused salad dressings, and premium energy recovery oils.

Case Study 1: Eliminating Shell Softening in Premium Softgel Batches (Seoul, South Korea)

Operational Challenge: A major functional supplement brand experienced significant softgel shell softening and leakage due to high acid values in inferior solvent-extracted Astaxanthin raw materials.

The Technical Execution: The formulation team replaced their old supply with our **AST-OL-10N** (Supercritical CO2 extracted, Acid Value ≤ 15.0 mg KOH/g).

✓ Commercial Outcome: Softgel structural failure and leakage rates dropped to absolute zero, batch yield improved by 18%, and the active shelf life was verified for a robust 3-year cycle.

Case Study 2: Developing odor-Free Topical Anti-Aging Serums (Paris, France)

Operational Challenge: A luxurious cosmetics brand faced customer complaints regarding the heavy fishy/algae scent in their newly launched premium facial oil series.

The Technical Execution: They formulated our low-odor cosmetic-grade **AST-OL-COS** (dissolved in premium Squalane carrier) into their oil phase.

✓ Commercial Outcome: Successfully launched a completely odor-free anti-aging product line with an elegant, natural peach-red hue, receiving massive praise from premium beauty retailers.

• Light-Proof & Oxygen-Barrier Aluminum Canisters

Supplied in high-grade 1kg, 5kg, and 25kg pharmaceutical-grade aluminum containers flushed with pure nitrogen to eliminate oxygen inside. Sealed tightly to safeguard raw bioactive molecules from oxidative decay.

• Strict Cold-Chain Storage Thresholds

Store in original unopened packaging below 15°C (long-term frozen storage below -18°C is highly recommended for preserving maximum active values). Keep away from direct light, heat, and moisture.

• Comprehensive Global Traceability Dossier

Every shipment includes batch-specific analytical sheets: Batch COA, HPLC active purity charts, heavy metals ICP-MS data, microbiological screening sheets, Non-GMO declarations, and Kosher/Halal certifications.

Q1: How do you prevent oxidation of Astaxanthin Oleoresin during transit and storage?

A: Natural Astaxanthin is a highly powerful singlet-oxygen quencher, which also makes it extremely susceptible to oxidation. We counter this by purging our high-barrier aluminum canisters with pure nitrogen gas, blending natural mixed tocopherols as active stabilizers, and strictly shipping under climate-controlled conditions.

Q2: What are the advantages of Supercritical CO2 extraction over organic solvent extraction?

A: Solvent extraction often leaves trace chemical residues (like hexane or ethyl acetate) in the oil, which can cause softgel softening or skin irritation. Our Supercritical CO2 extraction is a clean, physical process operating at low temperatures, resulting in a zero-residue, highly pure oil that preserves all natural nutrient structures.

Q3: How do you control the strong microalgae odor for cosmetic active formulations?

A: For **AST-OL-COS**, we implement an advanced proprietary physical molecular distillation step. By removing the highly volatile low-molecular weight odor compounds under a high vacuum, we significantly lower the heavy algal scent while leaving the active Astaxanthin molecules completely intact.

Q4: Is your Astaxanthin derived 100% from natural algae or synthetic raw materials?

A: We extract our active compounds exclusively from *Haematococcus pluvialis* microalgae, cultivated in secure, closed-loop glass photobioreactor systems. This yields predominantly (3S, 3'S) stereoisomers, which have been scientifically proven to possess up to 550 times the singlet-oxygen quenching power of synthetic equivalents.

Q5: What is the MOQ, and can we request small testing samples for HPLC validation?

A: Our industrial MOQ for commercial shipments is 5kg. However, for qualified pharmaceutical, supplement, and cosmetic brands, we provide 10g - 50g free evaluation samples alongside full batch COA and chromatographic profile data for your laboratory verification.
