Manucol is a brand name commonly used for sodium alginate, which is a salt of alginic acid derived from brown seaweed. Sodium alginate is widely used in pharmaceutical formulations as a gelling agent, thickener, stabilizer, and viscosity enhancer. It is especially important in antacid and wound dressing products due to its gel-forming properties upon contact with water or gastric acid.
Key points about sodium alginate (Manucol):
- It forms a viscous gum or gel in aqueous solutions.
- Used in controlled release formulations, topical gels, and as an excipient in tablets and suspensions.
- Differs from alginic acid, which is the acidic precursor and less soluble.
Other options:
- Alginic acid is the acid form, not the sodium salt.
- Carbopol is a synthetic polymer used as a thickening agent, not related to alginates.
- Guar gum is a different natural polysaccharide from guar beans, used as a thickener.
