Alginic acid is a natural polysaccharide aldehyde found in the cell walls of brown algae such as kelp and kelp. Chemical formula (C6H8O6) n. A linear copolymer formed by 1,4-bonding of β - D-mannuronic acid (M) and α - L-guluronic acid (G), the content of G and M in alginate has a significant impact on the gelling properties of fibers. Alginate exists naturally in the cytoplasm and plays a role in strengthening the cell wall. Alginate combines with various cations in seawater to form various alginates. The extract obtained from seaweed is usually sodium alginate. Sodium alginate has the characteristics of thickening, suspending, emulsifying, stabilizing, forming gel, forming film and spinning fiber. It has a long and extensive use in food, paper making, cosmetics and other industries, especially in the biomedical engineering field in recent years.
Usage
Gum derived from alginic acid which is obtained from brown seaweed genera, such as Macrocystis pyrifera. The derivatives are sodium, ammonium, and potassium ates of which the sodium salt is most common. They are used to provide thickening, gelling, and binding. A derivative designed for improved acid and calcium stability is propylene glycol ate. The s are soluble in cold water and form nonthermoreversible gels in reaction with calcium ions and under acidic conditions. Algin is used in ice cream, icings, puddings, dessert gels, and fabricated fruit.
Corrosive moisture sensitive
Algin (alginic acid) is used in cosmetic formulations as a thickener, stabilizer, and gelling agent. It is obtained from different varieties of brown seaweed.
Alginic Acid is the acidic, insoluble form of algin that is a white to yellowish fibrous powder obtained from brown seaweed genera, such as macrocystis pyrifera. the derivatives are soluble and include sodium, potassium, and ammonium alginate and propylene glycol alginate. it is used as a tablet disintegrant and as an antacid ingredient.
