General description

Sodium alginate is the sodium salt of alginic acid, a natural polysaccharide found in brown algae. It is generally used as a stabilizer and thickener in the food industry. Sodium alginate may undergo cross-linking in the presence of divalent cations such as Ca2+ to form biodegradable stable gels, which finds applications as a material for cell encapsulation and immobilization.

Application

Sodium alginate can be used to prepare:
  • Cationized casein-based polyelectrolyte complex for fragrance-controlled release applications.
  • Apple aroma microcapsules for cosmetic applications.

Packaging

1 kg in poly bottle
5 kg in poly drum

Other Notes
