What is alginate used for?

Alginate is typically used in the form of a hydrogel in biomedicine, including wound healing, drug delivery and tissue engineering applications. Hydrogels are three-dimensionally cross-linked networks composed of hydrophilic polymers with high water content.

What alginate means?

An alginate is a polymer derived from alginic acid and used as a thickener, binder, or lubricant. Alginates are polymers known for their gelling and thickening properties. The sodium salt of alginic acid, sodium alginate, is used to make substances thicker.

What is alginate powder?

Alginate is a powder material that contains sodium alginate, calcium sulfate, trisodium phosphate, diatomaceous earth, zinc oxide, and potassium titanium fluoride. When mixed with water, it makes a smooth gel-like consistency that sets firmly enough to mold.
