Usage
The high molecular substance, sodium alginate has the functions of suspending, thickening, emulsifying, bonding, etc., and is mainly used as a suspending agent, an emulsifier, a thickener, a capsule of a microcapsule, etc. in the medicament. Used as a binder for tablets (1% to 3%) and disintegrant (2.5% to 10%); used as a diluent in capsules; also used in the preparation of oral sustained release preparations because it can delay the drug from Release in water-soluble suspensions; widely used as thickeners and suspending agents (5% to 10%) in pastes, ointments and gels, and as stable in oil-in-water emulsions The agent (1% to 3%) is used. An aqueous solution of 0.5% to 2.5% can be used to smooth the erosion surface of the skin, allowing aqueous secretions to be removed and dried.
