| Alginic acid Usage And Synthesis |
| Chemical Properties | white to pale yellow-beige powder |
| Uses | corrosive moisture sensitive |
| Uses | algin (alginic acid) is used in cosmetic formulations as a thickener, stabilizer, and gelling agent. It is obtained from different varieties of brown seaweed. |
| Safety Profile | Moderately toxic by intraperitoneal route. When heated to decomposition it emits acrid smoke and irritating fumes |
| Purification Methods | To 5g of acid in 550mL water containing 2.8g KHCO3 are added 0.3mL of acetic acid and 5g potassium acetate. EtOH is added to make the solution to 25% (v/v) in EtOH, and any insoluble material is discarded. Further addition of EtOH, to 37% (v/v), precipitated alginic acid. Collect the acid and dry it in vacuo. [Pal & Schubert J Am Chem Soc 84 4384 1962.] |
