Transient Overview: Welcome to our SlideShare presentation on emulsions, a fascinating realm exactly where oil and drinking water appear together in perfect harmony. Join us as we unravel the science, applications, and benefits of emulsions.
This document discusses theories of dispersion and techniques for preparing emulsions and suspensions. It addresses four main theories of emulsion dispersion: viscousity idea, film or adsorption theory, wedge principle, and interfacial tension principle.
Connect with to Motion: Stimulate the viewers to take a look at more, experiment, and share their insights to the assorted environment of emulsions.
Emulsions could be prepared using various techniques depending upon the scale and ingredients, like the continental/dry gum system, English/moist gum process, or bottle technique
Suspensions need suspending agents to stop particles from settling as a consequence of gravity. Typical suspending agents consist of purely natural, semi-synthetic, and artificial polymers. The doc also discusses variables that impact sedimentation rate based on Stokes' equation and also the dissimilarities involving flocculated and deflocculated suspensions.
this ppt is quite simple and it has immence relevance in Actual physical pharmacy. it has been well prepared based upon the syllabus of WBUT & consists of informations of elimentary label...
The regularity of emulsions may differ from easily pourable liquids to semisolid creams. Their consistency will rely on:
The document discusses the qualities of suspensions and emulsions, which includes particle size, dispersion security methods, and customary pharmaceutical examples of Each individual form of biphasic liquid dosage sort.
It provides examples of equipment useful for homogenization like rotor-stator here homogenizers and ultrasonic homogenizers.
Proteins, polysaccharides, and their complexes made use of as stabilizers for emulsions: Alternate options to artificial surfactants inside the pharmaceutical field?
It describes the methodology for every exam, together with implementing ointments to pores and skin or in vitro to measure Qualities like absorption rate, penetration depth after a while, and microbial expansion inhibition. The aim is to ensure ointments deliver medicines securely and successfully through the skin within the meant level.
Odoo Awareness is a multipurpose productivity app which allows inner users to complement their organization understanding foundation and supply individually or collaboratively gathered information and facts.
Emulsion security and kind rely on variables much like the emulsifying agent utilized, its HLB value, and emulsion preparation approach. get more info Typical exams are used to recognize the emulsion kind and steadiness need to be ensured by right preservation, packaging, and storage.
Dilution exam: This check is significant to learn the solubility of the continual phase in the emulsion. As an example- In O/W emulsion, a dilution exam is done to know it's diluted with water or not.
