Agar Agar (CAS 9002-18-0) is a natural polysaccharide derived from red seaweeds (Gelidium, Gracilaria), supplied as a white to pale yellow or tan crystalline powder with no odor, that forms strong gels at low concentrations and serves food, pharmaceutical and cosmetic uses as a gelling, thickening and film-forming agent. It forms strong gels even at low concentrations and remains stable across pH variations.
