1. HPLC-Verified Astaxanthin Content Per Batch

Every production batch — powder, oil, or CWS — is analyzed by HPLC to confirm the declared astaxanthin content (1% to 10%) before release. The full analytical report, including the assay result and test conditions, accompanies each shipment.

2. Traceable Natural Microalgae Chain

Sourced from cultivated Haematococcus pluvialis microalgae with batch-level traceability from cultivation and harvest through supercritical CO² or solvent extraction to the finished format. The natural origin and purity profile are documented on the lot COA.

3. Food-Grade & Cosmetic-Grade Safety Testing

Each lot is tested for heavy metals (Pb ≤ 2 ppm, As ≤ 1 ppm, Cd ≤ 1 ppm, Hg ≤ 0.1 ppm) and full microbiological parameters (total plate count, yeast & mold, E. coli, Salmonella) to meet both food-grade and cosmetic-grade safety standards.

Complete Format Matrix — Powder, Oil & CWS

One product page, three manufacturing formats: astaxanthin powder (1%/2%/5%/10%), astaxanthin oil (5%/10%), and cold-water-soluble microcapsule powder (1%-10%). Order any strength in any format — all standardized and HPLC-verified.

Natural Source: Haematococcus Pluvialis

Astaxanthin is extracted from cultivated Haematococcus pluvialis microalgae — the natural biological source of this carotenoid pigment. No chemical synthesis, no dilution from other natural sources.

Dual-Grade Compliance — Food & Cosmetic

The same lot meets both food-grade and cosmetic-grade requirements, so one raw material can serve food coloring, nutraceutical, and personal-care manufacturing lines. Full documentation supports each market.

Standardized 1%-10% Concentrations

Concentrations are declared and verified rather than approximate: 1%, 2%, 5%, and 10% in powder form, 5% and 10% in oil, and 1%-10% in CWS microcapsules — reproducible dosing for your formulation team.

FUNCTIONAL ROLES

1. Beverages & Instant Drinks

Functional beverages, powdered drink mixes, and instant formulas. The CWS microcapsule powder disperses in cold water without oil-in-water emulsification equipment.

2. Softgels & Dietary Supplement Lines

Astaxanthin oil for softgel fill and tablets/capsules from the powder formats. Food-grade compliance and documented COA support reproducible supplement manufacturing.

3. Cosmetics & Skincare Bases

Cosmetic-grade oil and powder for creams, serums, and color cosmetics as a natural pigment and formulation base. One lot serves both food and personal-care lines.

4. Natural Red Food Coloring

Food-grade powder and oil for natural red coloring in confectionery, dairy, bakery, and processed food applications — a clean-label, microalgae-sourced colorant.

Q1: What is the difference between the powder, oil, and CWS formats?

A: Astaxanthin powder (1%/2%/5%/10%) is a dry, 80-mesh powder for tablets, capsules, and dry mixes. Astaxanthin oil (5%/10%) is a lipid-based oleoresin for softgels, emulsions, and creams. The CWS microcapsule powder (1%-10%) is microencapsulated to disperse in cold water, making it the format of choice for beverages and instant drinks.

Q2: Is the astaxanthin content standardized on every batch?

A: Yes. The declared strength (e.g., 5% powder or 10% oil) is assayed by HPLC on every batch, and the measured content is stated on the COA. The natural astaxanthin is sourced exclusively from Haematococcus pluvialis microalgae.

Q3: Do the powder and oil contain carriers or additives?

A: The astaxanthin powder and oil are declared as the extract itself without added carriers or fillers. The CWS microcapsule powder is microencapsulated with food-grade wall materials to achieve cold-water dispersion — the wall matrix is disclosed in the product specification and COA.

Q4: What are the packaging, grades, and supply terms?

A: Available in Food Grade and Cosmetic Grade. Packed in 1 kg aluminum foil bags (double PE bags inside) or 25 kg fiber drums, with oil in sealed amber drums. Free samples are available. Monthly supply capacity is 1,000 kg, shipped from Qingdao, Shanghai, or Tianjin; shelf life 24 months.
