Resin is a hydrocarbon secretion of many plants, particularly coniferous trees. ION EXCHANGE RESINS AND APPLICATIONS IN PHARMACEUTICAL TECHNOLOGY Ozge INAL *, Durhasan BOZ Ankara University, Faculty of Pharmacy, Department of Pharmaceutical Technology, Tandogan, 06100, Ankara-Turkey ABSTRACT Ion exchange resins (IER) are cross-linked, water insoluble polymers carrying ionizable functional groups on their repeating positions. Resins and Resin Combination: Resins are amorphous products of complex nature. 164-205, Edwin Jarald, Sheeja Jarald, 2007, “Textbook of Pharmacognosy and Phytochemistry”, First Edition, CBS Publishers and Distributors, 434-451, Michael Heinrich, Joanne Barnes, Simon Gibbons, Elizabeth M. Williamson, “Fundamentals of Pharmacognosy and Phytotherapy”, Churchill Livingstone, 86, S. Handa and V.K. Their chemical properties are exclusively based upon the functional groups present in these substances. A handful of adsorption devices that use activated charcoal or ion-exchange resins are called filters in commercial descriptions. Majority of them undergo slow atmospheric oxidation whereby there color gets darkened with impaired solubility. It is utilized extensively in the production of synthetic camphor. The inclusion of prefabricated pontics in FRC FDPs in particular may simplify the fabrication technique and provide more predictable outcomes for the final FRC FDP. Formation of the hydroxymethyl derivatives of phenol. They are usually insoluble in petroleum ether (a non-polar solvent) but with a few exceptions. Mei, in Comprehensive Medicinal Chemistry II, 2007. Cation-exchange resins are used for this purpose as well. Resins used: 1. Specific applications of ion-exchange resins are provided. Our research analyst will verify them and include it in the final deliverable report APPLICATION. It has also been used for preparing sustained release medicament formulation. The resin protects the plant from insects and pathogens. Kapoor, 2008, “Textbook of Pharmacognosy”, Second Edition, Vallabh Prakashan, 24, 51, 52, C. Trivedi, Medicinal Plants, Utilization and Conservation, Avishkar Publishers and Distributors, 347. To this end, plant derived natural resins are reviewed for their potential application as antimicrobial agents. Most of the resins are heavier than water. A small quantity of turmeric when boiled with milk and sugar, it helps to cure common cold and cough symptoms. The utility of these agents to stabilize drugs are evaluated. Resins are primary binders in all coatings and costruction markets including adhesives, coatings, elastomers, and sealants. The Indian Journal of Science and Technology defines filtration as a process in which solid particulate matter is removed from a fluid, which can be either … Myrrh acts as an astringent to the mucous membrane and hence it finds its application in oral hygiene formulations, such as: gargles, mouth-washes. It is predicted that additional therapeutic applications may be found for ion exchange resins. and G. sanctum Linn. On reaching a target viscosity, the reaction is stopped by cooling. Home Newsroom Pharmaceutical applications of polymers at Seqens. Denture teeth of this kind are fabricated in layers that make them not only look more aesthetic but also provide good adhesive properties. It is invariably prescribed with other purgatives, henbane or belladonna to prevent gripping in infants. para Cresol (UHP- Ultra high purity). A high purity grade of para Cresol for niche applications. Polypropylene resins are frequently us … Figure 5.2. Following are some of the Uses of Phenol. • This … Modern acrylic resin denture teeth provide higher abrasion resistance, improved adhesive properties and enhanced cosmetic-aesthetic values than their older versions (Kawara et al., 1991; Loyaga-Rendon et al., 2007). Application Process Thus resins play immense role in today’s pharmaceuticals. 2.4.2 Food and Drinks. Resins are usually mixtures of organic compounds. A few drugs containing oleo-gum-resins are as follows. Filtration is such a widely used process in the pharmaceutical industry as to be considered almost omnipresent. Resins, in general, are enriched with carbon, deprived of nitrogen and contain little oxygen in their respective molecules. However, PRF and RF prepolymers are made at a low formaldehyde molar ratio and thus are essentially novolac resins. The ridge-lap surface of denture teeth is less cross-linked and in some denture teeth brands organic and inorganic filler particles are added to this surface (Stober et al., 2006). Resins are regarded as complex mixtures of a variety of substances, such as: resinotannols, resin acids, resin esters, resin alcohols and resene. Microencapsulation: A Wide Array of Applications. We can offer various pore size and particle size products for from small molecule APIs to biologics. It is still employed in veterinary externally to prevent bandage chewing by dogs. Classification of Resins: The resins are broadly classified under three major categories, namely: Taxonomical Classification: The resins are grouped according to their botanical origin exclusively, such as: In this particular instance, it has been observed that the resins that usually occur in plants of the same natural order, may exhibit more or less related characteristics features. High wear resistance and good aesthetic properties of ceramic might also be beneficial for the provision of long-lasting FRC FDPs with good cosmetic-aesthetic values. Fracture of the pontics or fractures at the connector area are reported as typical complications with FRC FDPs (Vallittu and Sevelius, 2000). Hydrocarbon resins: A hydrocarbon resin is a C5/C9 aromatic hydrocarbon used in industrial applications. IER processes involve the reversible interchange of ions between a liquid and a solid phase, involving no radical change in the structure and properties of the solid. Plants secrete resins for their protective benefits in response to injury. Chromatography Resins Market size will witness significant growth in coming years impelled by increasing application of chromatography in pharmaceutical sector for separating chiral compounds along with rising usage in food industry for determining the vitamin C … It is valued for its chemical constituents and uses, such as varnishes and adhesives, as an important source of raw materials for organic synthesis, or for incense and perfume. The historical uses of ion-exchange resins and a summary of the basic chemical principles involved in the ion-exchange process are discussed. Ginger finds its wide applications in soft drinks, beverages, ginger beer and wine. It is extensively used for coating tablets and confections. They are hard, electrically non-conductive and combustible masses. Load-bearing capacities and fracture behavior of pre-shaped acrylic resin denture teeth (Perea et al., 2015b) was reported to increase when resin composite was used to fill the space at the bottom of the pontic once the FRC framework was in place. Because of the excess formaldehyde in the reaction mixture, resole resins have hydroxymethyl end groups that are not stable but continue to react even at room temperature. Prefabricated pontics such as acrylic resin denture teeth have superior mechanical strength and their occlusal adjustment is easier than those of ceramic ones (Powers, 2012). The inclusion of CAD/CAM manufactured pontic teeth may also overcome some of the shortcomings such as delamination of the veneering material (Göhring et al., 2002), discoloration (Monaco et al., 2003), and wear (Behr et al., 2003). Chemical Constituents: The capsicum contains 8-12% of an oleoresin capsaicin and a red coloring principle known as capsanthin. 184.108.40.206.2 Macroporous resins. Resin is a viscous compound hardens over time but softens on melting and does not react with water. 2.4.3 Personal Care. Direct fabrication of FRC FDPs in the mouth requires high clinical skills for establishing a satisfactory anatomical shape of the pontic. Consequently, the resins are broadly divided into resin alcohols, resin acids, resin esters, glycosidal resins and resene (i.e., inert neutral compounds). Resins are primary binders in coatings and construction applications, which provide adhesion and substrate protection. All resins are heavier than water , they are usually amorphous ,hard, and brittle solids. 2.5 Barrier Resins Consumption by Application. We are accredited with G.M.P Certificate by the Food & Drugs Control Administration (FDA), Gujarat for manufacturing bulk drugs. Reference Id: PHARMATUTOR-ART-1509. Resins are valued for their chemical properties and associated uses, such as the production of varnishes, adhesives, lacquers, paints, rubber and pharmaceutical uses. The prepolymers, which are stable, are cured by the addition of a hardener (e.g., paraformaldehyde or a formaldehyde solution). Ion Exchange Resins Market by Type (Cationic Resins, Anionic Resins), Application (Water, Non-Water), End-Use Industry (Power, Chemical & Petrochemical, Pharmaceutical, Food & Beverage), and Region - Global Forecast to 2025 The less cross-linked layer in the ridge-lap surface promotes better chemical bonding of the acrylic denture teeth to the FRC framework when such teeth are used as pontics in the fabrication of FRC FDPs. Ion Exchange Resins (IER) have been used by the pharmaceutical industry since the late 1950's, and are now recognized as one of the most important components of pharmaceutical manufacturing. Resins are more or less amorphous materials but rarely crystallizable in nature. As plant exudates by incisions, e.g. Considering that failures primarily occur at the pontic area and connector area, it is crucial to pay attention to the characteristics of the connectors when designing an FRC FDP. Jean Langenheim, 2004, "Plant Resins: Chemistry, evolution, ecology, and ethnobotany", Ann Bot , 93 (6): 784-785, Ashutosh Kar, 2007, “Pharmacognosy and Pharmacoboitechnology”, Second Edition, New Age International Publishers, 306-338, C K Kokate, A P Purohit, S B Gokhale , 2007,“Pharmacognosy”, Thirty ninth Edition, Nirali Prakashan, 405-442, T E Wallis ,2005 “Textbook of Pharmacognosy”, Fifth Edition, CBS Publishers and Distributors, Page no.483-496, D Trease and W C Evans, 2002, “Trease and Evans Pharmacognosy”, Fifteenth Edition, Saunders Publication, 257-288, Pulok K.

Qadry, 2009, “Pharmacognosy”, Fifteenth Edition, B.S. The pungency of capsaicin is not affected by dilute alkali, but is destroyed almost completely by subjecting it to oxidation with either KMnO4 or K2Cr2O7. It is widely used in the manufacture of printing inks, rubber, dark varnishes, sealing wax, linoleum and thermoplastic floor tiles. Thus, variety in compositions of resins makes them pharmaceutically useful and its contribution can not be ignored. Some resins also contain a high proportion of resin acids. Natural gums, extracts of the whole resins, as well as specific extracts, fractions, essential oils and isolated compounds from the above resins are discussed in terms of their antifungal, antibacterial, and antiprotozoal activity. Mutlu Özcan, ... Pekka Vallittu, in A Clinical Guide to Fibre Reinforced Composites (FRCs) in Dentistry, 2017. It is used for waterproofing cardboard, walls etc. The acceptance of CAD/CAM manufactured prosthetic solutions is increasing as a consequence of unpredictable results with some traditional methods and the time that they require (Li et al., 2014). Humans have been using plant resins for thousands of years. Their wide applications include surface coatings, paints, electrical equipment, construction materials, adhesives, and composite materials Gibson, 2016). It is used medicinally as a tonic, as a blood purifier, as an anthelmintic and finally as an aid to digestion. 5, with a resin solids content of about 35–50%. Resins dissolve in chloral hydrate solution, normally employed for clarification of certain sections of plant organs. However, the resins have not been reported in the Thallophyta i.e. Typical resin is a transparent or translucent mass, with a vitreous fracture and a faintly yellow or brown color, non-odorous or having only a slight turpentine odor and taste. One solution to overcome the design problem in this area is to place a similar amount of fibers at the bottom of the pontics and the connectors (Vallittu, 1998). Likewise, additional fiber reinforcement close to the prepared teeth was shown to increase the fracture strength of the FRC FDPs and reduce the incidence of fractures in the crowns (Vallittu, 1998). Inlay-retained FRC FDPs can be made either directly or indirectly. Occurrence of Resins in plants: In the plants resins usually occur in different secretory zones or structures. Pretreatment with capsaicin induces long-lasting desensitization of airway mucosa to various mechanical and chemical irritants. Authors: It is exclusively used across the globe as a condiment as curry powder. It is also used as a disinfectant expectorant in chronic bronchitis amalgamated with excessive discharge (Ashutosh Kar, 2007). This is achieved through the formation of a secondary IPN bonding that results after the dissolution of the ridge-lap surface of the acrylic denture tooth by resin monomers. Supplier from China. While some scientists view resins only as waste products, their protective benefits to the plant are widely documented. A few typical examples of such plant sources along with their specific secretary structures are given below: It has been observed evidently that resins are invariably produced in ducts as well as cavities; sometimes they do not occur in the so called specialized-secretory structures, but tend to get impregnated in all elements of a tissue, for example: Guaiacum Resin- is obtained from the heartwood of Guaiacum officinale Linn. It is used as a tool in neurobiological research. The layer between the PMMA beads and the cross-linked polymer matrix is named as semi-interpenetrating polymer network (IPN). Isolation of Resins: Pharmaceutical resins are obtained from the plants and animals by one of the following methods 2. Resins mostly got completely dissolved in a number of polar organic solvents, for instance: ethanol, ether and chloroform, there by forming their respective solutions which on evaporation, leaves behind a thin-varnish-like film deposit. Figure 2. Others: Our ion exchange resins have … By extraction with alcohol and precipitation with water, e.g. Shah Prakashan, Page no. It is used largely in ointments externally for the treatment of chronic skin diseases and eczema. It is employed externally as a counterirritant and rubefacient. It is extensively used for culinary purposes in ginger-bread, biscuits, puddings, cakes, soups and pickles.
