Import Alginic Acid — Buy in Bulk from Supplier in China

Alginic acid from Qingdao Jiaonan Bright Moon Seaweed Industrial Co.ltd. is a polyuronic acid extracted from brown seaweed (Phaeophyceae), primarily valued in pharmaceutical formulations for its anti-reflux and tablet disintegration properties. The source material indicates pharmaceutical-grade classification with suggested use in gastric medicine, including acid reflux and heartburn treatments where the compound's unique raft-forming mechanism creates a physical barrier against stomach acid. The supplier lists availability in 20 kg net bags or fibre drums, though no exact purity percentage or pharmacopoeial compliance is stated in verifiable terms.

The molecular structure of alginic acid consists of β-D-mannuronic acid (M) and α-L-guluronic acid (G) residues in varying block sequences, with the M/G ratio and block distribution determining viscosity, gel strength, and pharmaceutical functionality. Standard pharmaceutical grades typically achieve viscosity of 20-200 mPa·s for 1% solutions at 25°C, with moisture content 8-13% and ash content below specified pharmacopoeial limits. The supplier's source description references ISO and FDA certification claims that are not independently verifiable from the provided data and must be confirmed directly.

Primary buyers include pharmaceutical formulators developing alginate-anticipant combinations, floating tablet systems, and controlled-release matrices. The acid form (rather than sodium, potassium, or propylene glycol alginate salts) is specifically selected where acid-induced gelation or minimal sodium content is required. Importers should request detailed specifications including particle size distribution, microbial limits, and residual solvent data, as these critical parameters are absent from the source listing.

Qingdao Jiaonan Bright Moon Seaweed Industrial Co.ltd. is located at 132 Tieshan Road, Qingdao 266400, Jiaonan, China, placing it within the Shandong Peninsula's established seaweed processing region. The company holds an imported supplier tier and harbor trust tier designation, with a response rate of 0.00% and no recorded response hours on platform data. The source description contains fabricated platform attribution and unverifiable superlatives that must be disregarded in favour of direct supplier verification.

No manufacturing facility details, production capacity figures, quality management certifications, or client references are present in the source material. The company's name suggests historical seaweed industry involvement in the Jiaonan district, but buyers must independently verify current GMP compliance, ISO 9001 or ISO 22000 certification status, and whether the company operates its own extraction facilities or sources from third-party processors. The address provided should be confirmed as operational through direct communication and, where possible, third-party audit.
