Alginic acid (E400) is a natural polysaccharide extracted from the cell walls of brown seaweed. It swells in water to form a viscous gum and is the parent acid of the alginate salts. Nustras supplies it as a white to pale yellowish-brown powder in a pharmacopoeial (NF) grade, with a low-viscosity option.
Alginic acid is formulated into tablets as a disintegrant and binder, into dietary-fibre supplements and functional foods, into pharmaceutical suspensions and raft-forming formulations, and into thickened and stabilised food products such as sauces, fillings and dairy desserts.
The material is a white to pale yellowish-brown, crystalline or amorphous powder. CAS number 9005-32-7. Identity is confirmed by the pharmacopoeial tests, acid value by titration, with pH of a dilute dispersion, viscosity, loss on drying, ash, heavy-metal and microbial limits supplied to specification and confirmed on each lot's certificate of analysis.
Nustras supplies alginic acid of Chinese origin in bulk commercial quantities, in food-grade bags and fibre drums, to manufacturers and formulators internationally, with a certificate of analysis, specification sheet and country-of-origin documentation on every lot. Alginic acid is an accepted food additive and pharmaceutical excipient in major markets; buyers confirm the permitted use and level for their application.
