It is an ester of methacrylic acid used to make the polymer polyhydroxyethyl methacrylate, which was one of the first materials to be used successfully in flexible contact lenses. xH 3 PO 4. It was shown that when the combined gel + microemulsion system is placed onto hydrophobic grime, the latter is solubilized in the microemulsion droplets, which in turn diffuse back into the gel. Poly(hydroxyethyl) methacrylate (PHEMA) is a stable, optically transparent hydrophilic polymer that is one of the most widely applied hydrogel biomaterials. The scanning electron microscopy images show the porous structure of the gels. It is a colorless viscous liquid that readily polymerizes. Poly(2-hydroxyethyl methacrylate) (pHEMA) is a nonbiodegradable hydrogel used to fabricate soft contact lenses, and therefore has advantages in spinal cord repair applications as a clinically-approved polymer. Nanoparticles with controlled size and composition are then obtained. To introduce controlled degradation into PHEMA hydrogels, hydrolytically (Atzet et al., 2008) and enzymatically (Paterson et al., 2012) cleavable sequences have been incorporated. Figure 9.7. hydroxyethyl methacrylate’) consists of a mixture of phosphoric acid, mono-, di- and triesters with 2-hydroxyethyl methacrylate (HEMA) and diphosphoric acid, mono-, di-, tri- or tetraesters with HEMA. Early applications as pHEMA sponges placed into dorsal hemisections [315] soon evolved into multilayered guidance channels [316] which immobilized NGF [341] and BDNF [317] for sustained release and which had longitudinally oriented channels of tunable size created by templating the pHEMA over PCL microfibers [318]. Hydroxyethyl methacrylate (HEMA) refers to a chemical substance that is a monomer hydroxyester compound used to desensitize dentin structures and make polymers. On flat surfaces, strongly grafted and stable polymer films are formed. It is used in paint resins and emulsions, and binders for textiles and paper. ... 2-Hydroxyethyl Acrylate (HEA) 818-61-1 250 ± 50 MEHQ ≥ 98.5 % ≤ 2.5 mg KOH/g ≤ 0.15 10 Hydroxyethylcaprolactone Acrylate (HECLA) 110489-05-9 700 ± 200 MEHQ Poly hydroxyethyl methacrylate (PHEMA)-based hydrogels are the first synthetic hydrogels for pharmaceutical applications. Nicolas N. Madigan, Anthony J. Windebank, in Principles of Tissue Engineering (Fifth Edition), 2020. Optimal MBA-modified cements have some better mechanical properties in comparison to conventional cements [15]. Many studies aim to modify the properties of PHEMA to improve the degree of hydration, degradation, mechanical properties and transport properties. Besides controlled drug release and protein release, the hydrogel also has potential application in development of synthetic skin, breast augmentation, contact lens, etc. ECM peptide scaffolds were subsequently loaded with MSCs in a complete transection model, with MSCs not improving the degree of tissue and axon infiltration [324]. pHEMA-MMA formulations of conduits were produced using a liquid–liquid centrifugation casting technique to produce a gel-like outer layer and a macroporous inner layer [326] (Fig. Comprehensive Biotechnology (Second Edition). Depending on the physical and chemical structure of the polymer, it is capable of absorbing from 10 to 600% water relative to the dry weight. Despite evidence of adverse skin, eye, and throat reactions to these chemicals, they continue to be used … Acrylates (ethyl acrylate, ethyl methacrylate, and methyl methacrylate) are ingredients found in artificial nail products. The application of the gel softens the aged polymer without uncontrolled spreading of the fluid through the hydrophilic canvas support. A schematic representation for the multi-axial electrospinning. It has been applied to a variety of medical applications including contact lenses, dressings and drug delivery (Peppas et al., 2006). The grafting of biocompatible poly(hydroxyethyl methacrylate) onto titanium dioxide nanoparticles can be done in a very simple way [116]. PolyHEMA, in full poly-2-hydroxyethyl methacrylate, a soft, flexible, water-absorbing plastic used to make soft contact lenses. This system may eliminate the potential cytotoxicity in LCGICs caused by leached HEMA.

Such properties of this polymer make it suitable for fabrication of hydrophilic contact lens and artificial cornea (Kannan and Narayanan, 2015). Templated conduits were subsequently functionalized with ECM peptide gradients in a pHEMA copolymer system with 2-aminoethyl methacrylate [319] and in a methacrylamide-chitosan composite [250]. It is also used in high performance coatings for glass to guard against scratching and weathering and can be found in paint resins as well as binders for textiles and paper. Membrane fabricated by this method can modulate the controlled drug release at the target site (Bayramoğlu and Arıca, 2003). PHEMA-based hydrogels can be engineered to possess similar water content and mechanical properties as tissue, and exhibit excellent cytocompatibility. The light curable glass-ionomer cement system based on amino acid derivatives is free from HEMA. Data submitted and used for the evaluation are: Non‐toxicological data and information Structure, properties, spectra, suppliers and links for: (Hydroxyethyl)methacrylate, 868-77-9. An acrylamide gel-microemulsion composite system was used to remove aged synthetic adhesives (e.g., Mowilith DM5, a commercial adhesive based on vinyl acetate and n-butyl acrylate) from canvases (Pizzorusso et al., 2012; Chevalier et al., 2008). The first method has used GMA in combination with MMA to produce materials which have water contents in the range of 30–42%. Articles of 2-Hydroxyethyl methacrylate … The poly(hydroxyethylmethacrylate) is seldom used is isolation and is normally employed as a copolymer with other systems described in this chapter. This substance is used in the following products: adhesives and sealants. Sorina A. Gârea, ... Horia Iovu, in Clay-Polymer Nanocomposites, 2017. The hydrogels made of PHEMA are biocompatible in nature and possess tunable mechanical properties (Baker et al., 2009). In this work, using UV free-radical polymerization technique, a pH-sensitive membrane with interpenetrating polymer network has been formed for delivery of targeted drug. This monomer has been used in contact lens materials in two main ways. By changing the pattern of cross-linking with short hydrostable dimethacryloyl hydroxylamine, the researchers have been able to improve the mechanical property and low molecular weight product after degradation (Moghadam and Pioletti, 2016). MMA, Methyl methacrylate; NGF, nerve growth factor; pHEMA, poly(2-hydroxyethyl methacrylate); PLGA, poly(lactic-co-glycolic acid); SEM, scanning electron microscopy.

Dave, Ankur Gor, in Handbook of Nanomaterials for Industrial Applications, 2018. The obtained hybrid hydrogel may be included in the class of exfoliated nanocomposites that could be recommended as a potential candidate as a host for drug (paracetamol) loading with excellent properties such as low burst effect (phenomenon associated to the early release of drug), high drug encapsulation efficiency, and a modulated release profile of the drug [113]. Long-distance axonal regeneration through a T8 thoracic transection was demonstrated, with retrograde tracing studies identifying several brainstem nuclei to be the neuronal source of some axons traversing the graft [327]. IUPAC Standard InChIKey: WOBHKFSMXKNTIM-UHFFFAOYSA-N CAS Registry Number: 868-77-9 Chemical structure: This structure is also available as a 2d Mol file; Species with the same structure: Methacrylic acid, 2-hydroxyethyl ester Recently, positively charged pHEMA scaffolds, coated with laminin and loaded with iPSC-derived NPCs in a balloon compression model reduced the degree of cavitation, supported axonal sprouting and stem cell survival [325] (Table 58.4). The process has many advantages such as a short one-step reaction occurring at atmospheric pressure, ambient air, and room temperature in water. Besides, they are highly hydrophilic. Reversible plasticity shape memory of multi-walled-carbon-nanotube reinforced epoxy nanocomposites was studied for application in self-healing systems.67 Shape fixity, response temperature, and recovery speed were improved.67, The nano-reinforcement of an epoxy healing agent for vascular self-repairing fiber reinforced composites resulted in significant fracture toughness and healing efficiency improvement.68 The nanoenhanced healing agent increased the healing efficiency by 190%.68, After prolonged periodic bending fatigue, self-healing composite nanofiber mats revealed a restored, and even increased by 10%, cohesion energy.69 Self-healing resulted from the release of resin monomers and cure from the nanofiber cores, which permitted a polydimethylsiloxane polymerization reaction.69, Piero Baglioni, ... Rodorico Giorgi, in Nanotechnologies and Nanomaterials for Diagnostic, Conservation and Restoration of Cultural Heritage, 2019. HEMA is a monomer that is used to make various polymers. OECD SIDS 2-HYDROXYETHYL METHACRYLATE UNEP PUBLICATIONS 5 FULL SIDS SUMMARY CAS NO: 868-77-9 SPECIES PROTOCOL RESULTS PHYSICAL-CHEMICAL 2.1 Melting Point Unknown < - 60 °C 2.2 Boiling Point Unknown 205-220 °C at 1,013 hPa It was demonstrated that a poly(hydroxyethyl methacrylate) shell was successfully chemically grafted onto the surface of the TiO2 core without any significant influence on the morphology of the nanoparticles [116]. Physically cross-linked poly(vinyl alcohol) networks obtained through cryogelation, using one (FT 1) or three (FT 3) freeze-thaw cycles. Structural instability of the channel architecture was addressed by coil reinforcement and polymer with greater elastic moduli [329], but densities of axons did not improve, and the more rigid scaffold lead to the development of syringomyelia and caudal migration of the rostral stump in some transected animals (Table 58.4). The combination of PHEMA and PEG is a particularly pertinent example of its application in wound healing where the resulting framework was modified to carry MMP inhibitors such that, when placed on the wound bed—the activity of proteases within the matrix is reduced and healing can be reactivated. [4], HEMA lends itself well to applications in 3D printing as it cures quickly at room temperature when exposed to UV light in the presence of photoinitiators.

MMA is used widely and can be found as an additive in concrete, in adhesives, artificial joints, dentures, hairspray, nail polish, paints, textiles and windows. 4.23) can be radically manipulated through copolymerization and by cross linking [159]. Methacryloyl and acryloyl derivatives of the amino acids can be synthesized via the Schotten-Baumann reaction. CAS Number: 52628-03-2. Hydroxyethyl methacrylate is a clear, colourless liquid with a sweet odour which is soluble in water. TiO2 nanoparticles were synthesized by laser pyrolysis. The electronics and computer industries use methacrylate-based polymers to manufacture flat-screen computer monitors and televisions, as well … 2-Hydroxyethyl methacrylate, present at 100 mg/l, reached 92-100% of its theoretical BOD in 2 weeks using an activated sludge inoculum and the Japanese MITI test(1). It was invented by Drahoslav Lim and Otto Wichterlefor biological use. Thin hydrogel films are applied for sensing mechanism (Kikuchi and Okano, 2005; Blanco-López et al., 2004). The hydrogel of 2-hydroxyethyl methacrylate (p(HEMA)) is a light, flexible, biocompatible, and non-toxic material which presents no antigenic activity. [5] When combined with a suitable blowing agent such as BOC Anhydride it forms a foaming resin which expands when heated. Martens, in Biosynthetic Polymers for Medical Applications, 2016. Hydrogels based on poly(2-hydroxyethyl methacrylate) and MMT were prepared by in situ free radical polymerization. Another important methacylate polymer is poly (2-hydroxyethyl methacrylate) (HEMA). (A): image of FT 1; (B): image of FT 2 (bar is 1 μm). It is used in contact lenses, drug delivery systems, dental adhesives, and for several other biomedical applications. Polyhydroxyethylmethacrylate is hydrophobic; however, when the polymer is subjected to water it will swell due to the molecule's hydrophilic pendant group. 6). HEMA finds wide applications for drug delivery. Loading of the fluids occurs through simple immersion of the gel, allowing the system to equilibrate (typically for some hours). Wego is an importer of 2-Hydroxyethyl Methacrylate to numerous countries around the world. Figure 58.21. pHEMA tubes as copolymers with MMA. The swelling property of PHEMA is moderate and can be modulated by changing the thickness of gel and by changing the degree of cross-linking (Mabilleau et al., 2006; Davis and Huglin, 1991). (C) NGF releasing PLGA microspheres were cast against the inner surface of the conduit lumen by a similar method, using pHEMA-MMA channels coated with an inner layer of pHEMA and 1 wt.% PLGA 85/15 microspheres: (a) at 40× magnification for a 5 wt.% pHEMA layer; (b) a close-up of (a) at 220× magnification for a 5 wt.% pHEMA layer; and (c) at 200× magnification for a 10 wt.% pHEMA layer by SEM. 9.7). Despite being held by secondary bonds, these networks exhibit a mechanical behavior typical of solid-like chemical gels. (2-hydroxyethyl)- methacrylate is used in light curing polymer systems and high performance coatings for lasting high gloss against scratching, solvents, and weathering. 4-Methoxyphenol: 5 mg/m3 TWA Personal Protective Equipment Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. One of the disadvantages of this material is lower biodegradable property that limits its application in biological field 16. (Zahedi and Lee, 2007; Lu and Anseth, 1999). By continuing you agree to the use of cookies. pHEMA and pHEMA-co-methyl methacrylate (pHEMA-MMA) have been extensively developed for use as spinal cord scaffolds. PHEMA hydrogels are generally synthesised via the free radical polymerisation of meth(acrylates).

[3], When treated with polyisocyanates, poly(HEMA) makes a crosslinked polymer, an acrylic resin, that is a useful component in some paints. PHEMA in dry state is hard and brittle and after swelling it becomes flexible. A variety of surface modifications improve cell adherence and axonal extension, including incorporation of poly(l-lysine) and gradients of NT-3 [320]. This approach has been successfully patented and is targeted at DFU treatment [185]. Hydroxyethylmethacrylate or HEMA is the organic compound with the formula H2C=C(CH3)CO2CH2CH2OH. The presence of macropores allows the diffusion of the supramolecular aggregates (micelles) of the fluids into the core of the hydrogels. Deposition of polymer hydrogel on metallic implants improves the compatibility of implants and also develops controlled release device such as stent or microchips (De Giglio et al., 2011). These characteristics make them ideal scaffolds for loading and delivering water-based cleaning fluids (Mastrangelo et al., 2017). Among several derivatives, methacryloyl-β-alanine (MBA) has a particularly low solution viscosity and a high compressive strength. Amino acid acrylate and methacrylate derivatives were found to be suitable in light curable glass-ionomer cements. Copyright © 2021 Elsevier B.V. or its licensors or contributors. Figure 13.33. Surface cleaning of artworks: structure and dynamics of nanostructured fluids confined in polymeric hydrogel networks. It is a clear, colorless liquid with a characteristic odor. It may be used as a monomeric matrix in which 40nm silica particles are suspended for 3D glass printing. 128635-conf 2-hydroxyethyl methacrylate contains [organic chemical] united states: banglore air cargo: kgs: 18: 15,047: 836: nov 10 2016: 29181990: 2 hydroxyethyl methacrylate (2-hema) japan: nhava sheva sea: kgs: 14,000: 2,150,694: 154: nov 05 2016: 29161400: non hazardous chemical 2-hydroxyethyl methacrylate - (raw material for iol) - (1 box) Hydrogels based on poly(2-hydroxyethyl methacrylate) have been extensively investigated for a range of biomedical applications [183], but their oxygen permeability and biocompatibility have generated interest as tissue scaffolds [122,183,184]. Research group from Portugal has developed novel stereolithographic fabrication technique for the fabrication of multimaterial graded scaffolds using UV and thermal energy for cross-linking the polymer (Pj, 2008). Besides high load bearing ability, this polymer also exhibits the resistance to crack propagation 18. A similar casting technique was employed for sustained release of NGF from inner lumen coatings or embedded microspheres [328]. By applying 2-hydroxyethyl methacrylate locally to sensitive teeth, sensitive areas in the teeth get sealed and block the dentinal tubules at the dentin surface from stimuli that cause pain. The applicant has submitted a dossier in support of its application for the authorisation of the substance 2‐hydroxyethyl methacrylate phosphate to be used in plastic food contact materials. Wego supplies 2-Hydroxyethyl Methacrylate to various industries for a variety of applications and uses. The hydrogels made of PHEMA are biocompatible in nature and possess tunable mechanical properties (Baker et al., 2009). Different amounts of MMT were dispersed in deionized water and stirred for 2 h followed by sonication (1 h). When formulated as a hydrogel block, insertion of pHPMA into a thoracic hemisection improved animal locomotor scores and electrophysiologic parameters over controls in addition to supporting axonal regeneration within the hydrogel matrix [332] (Table 58.4). 2-Hydroxyethyl methacrylate (HEMA) was the first monomer to be used to synthesize hydrogels for biomedical applications.The water swelling properties of HEMA are enhanced by copolymerization with more hydrophilic monomers. Physical Chemistry Chemical Physics 19, 23762–23772. Besides high load bearing ability, this polymer also exhibits the resistance to crack propagation 18. In the second step, the monomer was intercalated in the clay interlayer spaces and then the polymerization process was promoted. Modification of surface charge, with the addition of quaternary amine groups or of a second methacrylate subtype [321], is another approach taken to improve cell/neurite migration and encapsulation, as many cell types adhere better to a positively charged surface. Manufacturers rely on Wego for a reliable, efficient, and cost-effective supply of 2-Hydroxyethyl Methacrylate. PHEMA and chitosan blend is commonly applied in drug delivery. Further improvements in supraspinal neuronal regeneration were achieved by filling the conduit channels with extracellular matrices and soluble trophic factors (FGF-1 and NT-3). OSHA Vacated PELs: 2-Hydroxyethyl methacrylate, stabilized: No OSHA Vacated PELs are listed for this chemical. As with the other systems described here, the native structure (shown in Fig. The polymerization rates of these methacrylate esters are within the same range as Ethyl Methacrylate. It is known that unreacted 2-hydroxyethyl methacrylate (HEMA) in current resin-modified glass ionomer cements shows potential cytotoxicity to pulp and surrounding tissues [24]. HEMA is a monomer that is used to make various polymers. Hydroxyethyl Methacrylate. Early work demonstrated the capacity of a colloid pHPMA gel, with [330] or without [331] the incorporation of ECM peptide, to support regeneration when injected into a complete transection defect. J. Davis, A. McLister, in Smart Bandage Technologies, 2016. Methacrylic monomer is a chemical used in UV inks, adhesives, lacquers, dental materials and artificial nails. 12.3 Bioaccumulative potential. The softened adhesive is then easily removed without inducing mechanical stress on the canvas fibers. Methyl methacrylate, or MMA, is a substance used in the manufacture of a variety of plastics and other products. Because of this property, it was one of the first materials to be successfully used in the manufacture of soft contact lenses. Beta ‐Hydroxyethyl Methacrylate Ethylene glycol methacrylate Glycol Methacrylat Glycol monomethacrylate GMA Mhoromer Heme ‐a This may not be a complete list as manufacturers introduce and delete chemicals from their product lines.
