WebAll emulsifying agents used in the system should be odorless, nontoxic, nonirritant, chemically stable, inert, and chemically nonreactive with other excipients. Commonly used emulsifying agents include polymers (Spans and Tweens), sodium lauryl sulfate, sodium dioctyl sulfosuccinate, and tragacanthins (Haba et al., 2014). WebHence, these sols are called reversible sols. Examples of lyophilic sols include sols of gum, gelatine, starch, proteins and certain polymers in organic solvents. 2) Lyophobic colloids. ... Lyophobic sols need stabilizing agents to keep the dispersed phase from precipitating out. WebThese sols are irreversible in nature. Lyophobic sols need stabilizing agents for their preservation. Examples of Lyophobic Sols – Ferric hydroxide sol, aluminum hydroxide sol, arsenious sulfide sol, etc. Step 2: Hydrophobic sols get easily coagulated because these sols are stabilized due to the charge on the particle. tekst pjesme iz daleka rasta
