Mixtures

• Mixtures

  • particle size > 0.5mcm
  • aqueous liquid preparation which contains suspended (suspensoid), insoluble, solid substance
  • insoluble substance may be held in suspension
  • suspending or thickening agent since the insoluble substance does not make the mixture very viscous
  • insoluble substance
  • must be in a very finely divided state and it must be uniformly distributed throughout the preparation
  • this is accomplished by the use of colloid mills, special methods of precipitation and suspending agent
• Reasons for having the insoluble substance in a finer state of sub-division

  • the more active they become as adsorbent and protectives when in contact with the inflamed areas
  • suspended more readily and settle out much slowly than large particles, thus enabling the patient to obtain uniform doses of suspended particle
  • to increase palatability of the preparation with the use of colloidal suspending agent
  • lotion: colloidal dispersion (between 1.0 nm & 0.5 mcm)
  • magmas and gel: 0.5 mcm - 10 mcm
  • mixture: > 0.5 mcm
