What is hydroxyethyl methacrylate used for?
HEMA is produced for the use as monomer for production of polymers and as intermediate for synthesis of other methacrylate esters. The substance is manufactured in industrial settings in closed systems and used by industry for manufacture of polymers in closed and semi-closed systems.
What is HEMA used in?
HEMA is a monomer used in nail products usually used for adhesion and dilution.
What is the chemical name for HEMA?
|Other names HEMA; hydroxyethylmethacrylate; glycol methacrylate; glycol monomethacrylate; hydroxyethyl methacrylate; ethylene glycol methacrylate; 2-(methacryloyloxy)ethanol|

Is methacrylate the same as HEMA?
2-Hydroxyethyl methacrylate (HEMA) is a methacrylate monomer used in polymer-based dental-restorative materials.
What is hydroxyethyl methacrylate found in?
It is found in paint resins and binders for textiles and paper. It is also found in metal coatings as an adhesion promoter. How can you avoid contact with (2-hydroxyethyl)-methacrylate?
Is hydroxyethyl methacrylate safe?
In consideration of the animal toxicity data, the CIR Expert Panel decided that these methacrylate esters should be restricted to the nail and must not be in contact with the skin. Accordingly, these methacrylate esters are safe as used in nail enhancement products when skin contact is avoided.
What is 2-hydroxyethyl methacrylate in?
2-hydroxyethyl methacrylate (HEMA) is an acrylic monomer. It is used in light curing polymer system and high performance coatings for lasting high gloss against scratching, solvents, and weathering.
Can you be allergic to acrylates?
How does acrylate allergy present? In individuals allergic to one or more specific acrylates, direct contact with acrylate monomers produces classic allergic contact dermatitis. The dermatitis is usually confined to the area of contact and may cause itching, burning, scaling, hives, and blistering.
What is hydroxyethyl methacrylic acid?
Description. 2-Hydroxyethyl Methacrylate is a hydroxyester compound and a resin monomer used in desensitizing dentin. 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.
Is hydroxyethyl methacrylate a resin?
Resin monomer 2-hydroxyethyl methacrylate (HEMA) is a potent inducer of apoptotic cell death in human and mouse cells.
Is HEMA safe?
The molecular size of HEMA is however much smaller and can be more easily absorbed into the skin. In contrast, the European Scientific Committee for Consumer Safety (SCCS) – published a report stating that HEMA may be safe when applied appropriately to the nail plate.
Is HEMA toxic?
Cell toxicity of HEMA – the role of oxidative stress The methacrylate monomer 2-hydroxyethyl methacrylate (HEMA) is commonly used in polymer-based dental restorative materials. Several studies have shown that HEMA is toxic in vitro. Increased oxidative stress has been suggested as a key event in this response.
What is 2-hema (hydroxyethyl methacrylate)?
2-Hydroxyethyl Methacrylate (2-HEMA) is a combustible substance. At the temperatures above 97 °C, it can form explosive mixtures of vapor with air. The substance is irritating to the eyes, skin and respiratory tract. If this fluid is swallowed, aspiration into the lungs can lead to chemical pneumonitis.
Is 2-hydroxyethyl methacrylate soluble in water?
2-Hydroxyethyl Methacrylate 2-Hydroxyethyl methacrylate is perhaps the most widely studied and used neutral hydrophilic monomer. The monomer is soluble, its homopolymer is water-insoluble but plasticized and swollen in water.
What is the toxicity of hydroxyethyl methacrylate?
toxicologically, hydroxyethyl methacrylate appears almost three times as toxic as the methacrylic ethyl ester. Clayton, G.D., F.E. Clayton (eds.) Patty’s Industrial Hygiene and Toxicology. Volumes 2A, 2B, 2C, 2D, 2E, 2F: Toxicology. 4th ed.
How does 2-hydroxyethyl methacrylate affect the environment?
2-Hydroxyethyl methacrylate’s production and use in acrylic resins, enamels, and as a binder for non-woven fabrics may result in its release to the environment through various waste streams. If released to air, a vapor pressure of 0.126 mm Hg at 25 °C indicates 2-hydroxyethyl methacrylate will exist solely as a vapor in the ambient atmosphere.
