Usage:
Alginic Acid is mostly used in pharmaceutical industry as agent to prevent obesity and new medicine to treat stomach trouble. In the same time, Alginic Acid is an important raw material to produce propylene glycol alginate, polysaccharide sulphate etc.
1. Pharmaceutical industry
Alginc Acid is used as the main material for disintegrants and agent for the new medicine PSS, with the strong dispersing and emulsifying character.
2. Food industry
Alginic Acid can be combined with many ion, forming into a series of alginate product. It is widely used to manufacture health food or health food additives, such as sodium alginate, potassium alginate, calcium alginate, etc.
3. Environment protection
Alginic Acid can be used to treat and purify waste water with the character of its strong absorbility.
