For the First Half of 2022

Alginate, also known as alginic acid is an organic substance that is obtained from seaweed. The price of seaweed (used as a feedstock )determines the global sodium alginate price patterns. The vast bulk of the world's seaweed demand is satisfied by Southeast Asia.

Indonesia is the world's largest producer of seaweed, but recent price fluctuations have made it challenging for farmers to make a livelihood. Because China is the largest country that processes seaweed, China's strong demand is a major factor in feedstock pricing.

The Chinese government's zero-tolerance covid regulations had a negative impact on the manufacturing sector. Even once restrictions were lifted, the turnaround was not ideal since high pricing and supply-side restraints negatively impacted market demand sentiment.

The price of seaweed in Indonesia was adversely impacted by the decline in Chinese demand, which also had an impact on the price trends of sodium alginate. The Indonesian government's export limitations as well as the devaluation of the currency against US dollars caused seaweed prices to further collapse. Seaweed cost 2.97–4.21 USD/kg in China whereas it cost 3.5–6.87 USD/kg in Europe.

However, due to increased demand on the local US market, seaweed prices were somewhat increased, averaging 10.55 USD/kg. Due to consistent demand from the pharmaceutical and dental industries, sodium alginate pricing managed to stay afloat in the worldwide market despite fluctuating trends in seaweed prices.

Sodium alginate (NaC6H7O6) is a 1,4-D-mannuronic (M) and L-guluronic (G) acid-based linear polysaccharide derivative of alginic acid. A component of marine brown algae's cell walls, sodium alginate includes between 30 and 60 percent alginic acid. Alginac acid is transformed into sodium alginate, which makes it water soluble and facilitates extraction. Only two bacterial genera, Pseudomonas and Azotobacter, can produce bacterial alginates, which are employed for adhering to surfaces and protecting cells from the environment by creating biofilms.

Production Processes

  • Production of Sodium Alginate from Alginic Acid Method

In this method, chopped wet seaweed is treated with diluted formalin to create sodium alginate solution. To separate the sodium alginate solution from the seaweed residue, sodium carbonate is next added. Alginate acid is created by mixing sodium alginate solution with hydrochloric acid, followed by the removal of water. Alginic acid is combined with sodium carbonate and alcohol to create sodium alginate. The powdered form is eventually achieved when it has been dried and ground.


The displayed pricing data is derived through weighted average purchase price, including contract and spot transactions at the specified locations unless otherwise stated. The information provided comes from the compilation and processing of commercial data officially reported for each nation (i.e. government agencies, external trade bodies, and industry publications).
