Lan Burgs highest exports volumes are generated through trade of the raw material Hyaluronate Acid (HA). HA is mainly produced in China and often processed into food and cosmetics. Depending on the molecular weight, it can be divided into four categories: oligo, small molecular, medium molecular (regular) and high molecular HA. Most products just contain 0.5 to one percent of HA as its powder usually is dissolved in water to form a transparent solution.
