Selection based on HLB for an emulsion which may be o/w or w/o may be given as follows First method: To produce emulsions of o/w type emulsifiers in the HLB value range of 8-18 are tried and for w/o type HLB 3-16 are tried. Advantages & Disadvantages of Natural & Chemical Fertlilzers. Whether we are farmers or not, we all know that the success of any plant relies on how it is cared for. This type of chromatography separates the molecules based on the volatility of a substance. Floor covering is the term generally described for any Finish material applied over a floor structure to provide a walking surface. Notwithstanding the sort, nonetheless, most creams are emulsion-based. The main advantages and disadvantages of Pharmaceutical Suspension are stated below: Advantages. i) It is easy to dispense unstable or degradable drugs in solution form. The turnkey option has been used for a long time, mainly in building civil infrastructure projects, or with public and governmental bids, or when the project has a high level of complexity and there is a well-defined scope on behalf of the owner. evaporation involves the formation of an emulsion between polymer solution and an immiscible contin-uous phase whether aqueous (o/w) or non-aqueous. This is different from other mediums, such as water or glycol, where refractive indexes change each time light hits … the dispersed emulsified latex is mixed in the cement mortar. There are different reasons why geotextile fabric is nowadays used, with bulk material quantities being utilized for more projects. Emulsion paints contain 50-60% of solids dispersed in the water-based dispersion media consisting of water and up to 5% of water miscible organic Solvents (alcohols, glycol ethers). Pharmaceutical applications of emulsions widened especially after micro and nano-emulsion emergence. Lipid dosage forms are attractive delivery systems for hydrophobic drug molecules. By contrast, in bulk and solution free-radical polymerization, there is a tradeoff between molecular weight and polymerization rate. Gas chromatography (GC) is an analytical method which is used for the separation of an volatile substance from a give mixture of compounds which are very difficult to separate and analyse. The ingredient consisting of cement, aggregates, and monomer is mixed with water and the monomer is polymerized after placing the concrete into forms. This section will present more detailed information about the Used to treat an assortment of conditions, to a great extent skin-related (e.g. This technique presents several advantages, such as high The emulsion and evaporation method suffer from the limitation of poor entrapment of hydrophilic drugs .Therefore to encapsulate hydrophilic drug the double emulsion technique is Using mouthwash is known to keep breath fresh and avoid the build-up of various bacteria in between the corners of the teeth. emulsion is shown in the diagram above. Double Emulsion and Evaporation Method: point. The applications of double-emulsion droplets in biomedical fields, including cell encapsulation, drug delivery and controlled release, and synthetic biology are also discussed. The disadvantages of suspensions as pharmaceutical products include the following: 1. photographic emulsion, and each pixel of an electronic imager collects a finite number of photons during the exposure time. The substance with more volatility will separate out quickly In general, Both the terms refer to the same but the term floor covering refers to loose-laid materials. The standard deviation for a Poisson distribution is the square root of the average value, provided the average value is greater than - Require some initial training in order to operate the equipment, and you must take care in conducting the process because you’re working with high temperatures, a heat source, pressurized containers and volatile oils. Other method includes the use of a micro fluidizer to produce micro-emulsions, sonication and potentiometrics dispersion. The Benefits and Disadvantages of Using Mouthwash. Advantages – (i) As the process is based on chemical reactions in liquid phase, it is very simple technique. Providing the emulsion, the resultant product has a much smaller particle size than the emulsion produced by conventional agitation. There are some distinct advantages and disadvantages for each type of polymerization. Disadvantages of emulsion polymerization include: Surfactants and other polymerization adjuvants remain in the polymer or are difficult to remove; For dry (isolated) polymers, water removal is an energy-intensive process; Emulsion polymerizations are usually designed to operate at high conversion of monomer to polymer. Advantages: • Solvent acts as a diluent and aids in removal of heat of polymerization. 8 Advantages and Disadvantages of Organic Manure. 2. • Thermal control is easier than in the bulk. Different variations are now available on the market, bringing in numerous advantages, including the following: Emulsion is one of the popular system since many decades. oil-in-oil emulsion as a potential for controlled drug release oil-in-oil emulsion can be used for water unstable compounds Better penetration through membranes and higher bioavailability Disadvantages: Due to incorporation of oily solvent there may chances of oxidation of oil phase. Ans. Disadvantages & Advantages of an GC. With all types of microemulsions, water–oil–water type microemulsion offers unique advantages, including these: • Degradation of proteins is effectively reduced due to the use of relatively mild conditions during the formulation process of microemulsions. ... is the most often used explosive in mining industry. • Solvent reduces viscosity, making processing easier. Advantages of emulsion polymerization include: High molecular weight polymers can be made at fast polymerization rates. Herein, this paper first reviews the state-of-art approaches for fabricating double-emulsion droplets and discusses their advantages and disadvantages. The low-energy emulsification includes emulsion inversion point, phase inversion temperature, and spontaneous emulsification [53]. Pharmaceutical suspensions are fundamentally unstable and for this reason, it requires formulation skill to ensure that the physical stability of the formulation is retained over the period of the shelf-life. The pixel-to-pixel variation for a uniformly reflecting surface will be Poisson distributed. • Difficult to remove solvent from final form, The natural polymers are - Higher initial cost for investment in the equipment needed to execute the process successfully. Advantages of using a combination of cement and bitumen emulsion are: • improved adhesion of the bitumen to the aggregate; • more rapid gain in strength, enabling the road to be opened to traffic quicker; and • improved ultimate strength of the recycled layer. Single emulsion technique: [2] The micro particulate carriers of natural polymers i.e. This concrete is produced by integrating an emulsion of polymer or monomer in portland cement concrete. The therapeutic agent is dissolved in the formulation and is therefore immediately available for absorption. Advantages and disadvantages of pharmaceutical solutions for oral administration Advantages Therapeutic agents can easily be administered orally to individuals who have difficulty in swallowing, e.g. In order to improve drilling rate, low gel oil package water emulsion drilling fluid was widely used from the mid-1970s. Advantages Easy to manufacture Cost effective Simplest and most widely used explosive Low density. Both methods have their advantages and disadvantages.
