Brief Overview: Welcome to our SlideShare presentation on emulsions, an interesting realm where by oil and h2o arrive collectively in fantastic harmony. Join us as we unravel the science, purposes, and great things about emulsions.
Widespread inorganic salts are bentonite, aluminum magnesium silicate, and aluminum hydroxide. Artificial agents contain carbomers and colloidal silicon dioxide. Suspending agents help stabilize suspensions by rising viscosity and slowing particle sedimentation according to Stokes' law. They prevent caking and will be resuspended with agitation.
This doc discusses in-process excellent Command tests for pharmaceutical suspensions. Some key exams mentioned include things like Visible inspection of visual appearance and purity, measuring Houses like density, pH, clarity and sedimentation quantity as time passes.
The higher HLB quantity would show the emulsifier has numerous hydrophilic groups on the molecule and as a consequence ought to be a lot more hydrophilic in character.
Visible: Molecular illustration illustrating the interaction in between emulsifying agents and oil-water interfaces.
Ophthalmic drug delivery aims to treat eye diseases by several dosage types that administer prescription drugs topically, intraocularly, or periocularly. Prevalent dosage kinds contain answers, suspensions, and ointments but they are promptly drained from your eye. Newer sustained launch kinds consist of gels, inserts, and implants that more info keep drug amounts in the attention as time passes.
Emulsifiers presently used in foodstuff output are possibly purified natural merchandise (both from plant or animal origins) or artificial chemical substances that have extremely similar constructions to the natural merchandise.
The doc discusses the properties of suspensions and emulsions, such as particle measurement, dispersion security procedures, and customary pharmaceutical samples of Every single form of biphasic liquid dosage sort.
This doc supplies an outline of tablet formulation and production. It discusses the definition and advantages of tablets as a preferred dosage type. It describes different types of tablets like compressed, enteric coated, and chewable tablets.
Attendees learn how to recognize and mitigate possible pitfalls And just how To guage the effectiveness of safety measures.
It get more info discusses different types of tablets like compressed and molded tablets. It provides specifics on assessing the appearance, hardness, friability along with other Homes of tablets and describes assessments like pounds variation, content uniformity, and dissolution applied to ensure tablets satisfy requirements.
Lecithin (a phospholipid derived from egg yolk) creates o/w emulsions as a result of its sturdy hydrophilic character. Animal derivatives are more likely to induce allergic reactions and so are subject to microbial progress and rancidity. Their advantage is in their capacity to guidance development of w/o emulsions.
24. Auxiliary strategy An emulsion well prepared by other techniques can also commonly be improved by passing it through a hand homogenizer, which forces the emulsion by way of a really tiny orifice, minimizing the dispersed droplet size to about five microns or less.
Systems is often stabilized thermodynamically by minimizing interfacial tension or floor location, or kinetically through Brownian movement and managing sedimentation charge. Lastly, it outlines ideal functions for dispersed systems like simplicity of redispersion, steadiness, and pleasing sensory Houses.
