Suspending agents

• a suspending agent that is transparent, odorless, tasteless, and can be accessed as a strip or coarse/fine powder. It is able to form gels in very dilute solutions (0.5% to 1.0% of Agar), and it is mainly used for culturing microorganisms and stabilizing and thickening suspensions by forming a gel matrix, which traps solid particles and prevents them from settling

  Agar
• a suspending and rheological agent that can be hydrated up to 12 times their weight at high temperatures. Additionally, it is used in concentrations of 2 or 3% for external use such as calamine lotion. It is mainly used to suspend particles in liquids, bind tablets together, and stabilize emulsions by adsorbing oil-water interface, and present droplets from coalescing - forming a protective layer around the oil droplets and thereby maintaining the stability of the emulsion.

  Bentonite
• a suspending agent, emulsifier, and binding agent. It is used up to 0.5% concentration for external preparation. It increases the viscosity of liquid formulations, which helps in suspending and stabilizing solid particles.

  Carbomer
• The most commonly used derivative of carbomer, due to its versatility and ease of use, since this derivative is usually available in powder form. Additionally, It is compatible with a wide range of other pharmaceutical ingredients, making it suitable for various applications

  Carbomer
• a white to almost white odorless, tasteless, granular powder. It is easily hydrated in water at all temperatures to produce viscous clear solutions, providing a stable environment for suspended particles and adsorbing the oil-water interface.

  Carboxymethyl cellulose sodium
• a derivative of cellulose that is utilized to suspend solid particles in liquids, thicken solutions, and stabilize formulations. It forms a gel-like structure when dispersed in water, which effectively suspends solid particles by trapping them in the gel network.

  Hydroxyethyl cellulose
• Like the previously mentioned hydroxy-cellulose derivative, also forms a gel when dispersed in water. It suspends solid particles, bind tablet ingredients together, and form films in oral thin films or coatings. Tablet compression may result in the roughening of the tablet’s surface, which can affect the appearance and stability of the tablet. It can be used to coat the surface by forming a thin film on the surface of tablets and capsules


  Hydroxypropyl cellulose
• Another cellulose derivative in which it’s employed to suspend solid particles in liquids, thicken solutions, and bind tablet ingredients together

  Methylcellulose
• White to greyish-white coloured, greasy powder that is free from gritty particles. Forms colloidal suspension in water and prevents them from settling due to its adsorptive agent.

  Kaolin
• Natural gum obtained from the sap of certain plants. Has pseudo plastic properties. Forms viscous aqueous solutions and suspended solids, bind tablet ingredients, and stabilize emulsions

  Tragacanth
• A type of magnesium aluminum silicate, which forms a colloidal suspension in water, preventing them from settling. It can also act as an adsorbent through oil-water interface and stabilize suspensions by preventing phase separation and sedimentation.
