Wetting agents hydrophilic colloids

The processes involved in the formation of suspensions are shown in Fig. 2. The flocculated state (C) may be reached either directly by wetting and dispersing hydrophobic particles (A) with a suitable flocculating surfactant, or indirectly by first wetting and dispersing to produce a dispersed or peptized particle (B) with a suitable surfactant and then flocculating with a suitable agent such as a hydrophilic colloid or polyelectrolyte. 

Use Food additive (processing aid in sugar industry, stabilizer for hydrophilic colloids), wetting agent, dispersant, emulsifier.
