Stabilizing agents algin

In topical formulations, sodium alginate is widely used as a thickening and suspending agent in a variety of pastes, creams, and gels, and as a stabilizing agent for oil-in-water emulsions. 

In skin care products it act as emulsion stabilizer thereby provide a soothing and silky feel to the skin. Alginate in occasionally found in tooth products as a bonding agent. Alginate absorbs water easily and therefore is used in facial masks as filmogens.

The viscosity of an emulsion can be of crucial importance for its stability, especially the viscosity of the external phase. A high viscosity reduces creaming and also lessens the tendency of particles to coalescence and produce phase separation. Examples of the widely used viscosity-imparting agents are alginates, bentonite, carboxymethylcellulose, polyvinyl pyrrolidone, hydroxypropylcellulose, and carbomer. 

Recently, sodium bicarbonate has been used as a gasforming agent in alginate raft systems and in floating, controlled-release oral dosage forms of furosemide and cisapride. Tablet formulations containing sodium bicarbonate have been shown to increase the absorption of paracetamol, and improve the stability of levothyroxine. ...
