Ethyl methacrylate is the organic compound with the formula C2H5O2CC(CH3)=CH2.
A colorless liquid, Ethyl methacrylate is a common monomer for the preparation of acrylate polymers.
Ethyl methacrylate is typically polymerized under free-radical conditions.
Ethyl Methacrylate is the ester of ethyl alcohol and methacrylic acid
used as the major structural monomer of artificial fingernail formulations that are cross-linked with one or more multifunctional methacrylates.
Ethyl methacrylate monomer is polymerized rapidly and very little free monomer is available even during filing of the fingernails.
Showed little evidence of irritation, although case studies report allergic contact dermatitis as a result of exposure to Ethyl Methacrylate and related methacrylates with application of artificial fingernails.
Occupational contact dermatitis from acrylates and methacrylates are also reported, with some evidence for cross-reactivity between the two chemical classes.
Based on the sensitizing potential of this ingredient the CIR Expert Panel recommended that fingernail enhancement formulations with Ethyl Methacrylate be applied only by trained individuals and that the ingredient not be used in products intended for retail
sale (currently, these products are believed to be sold only for application by a trained individual).
Because of the low likelihood of significant exposure if such formulations are applied properly, the Expert Panel concluded that the
ingredient is safe as used, with the caveat that skin contact should be avoided.

Fire Hazards - Flammable - 3rd degree, Reactive - 2nd degree
Cosmetics - Binding; Viscosity controlling
Industry Uses of Ethyl methacrylate:
Intermediates
Handling and Storage of Ethyl methacrylate:
Nonfire Spill Response of Ethyl methacrylate:
ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area).
All equipment used when handling the product must be grounded.
Do not touch or walk through spilled material.
Stop leak if you can do Ethyl methacrylate without risk.
Prevent entry into waterways, sewers, basements or confined areas.
A vapor-suppressing foam may be used to reduce vapors.
Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers.
Use clean, non-sparking tools to collect absorbed material.
LARGE SPILL: Dike far ahead of liquid spill for later disposal.
Water spray may reduce vapor, but may not prevent ignition in closed spaces.
Safe Storage of Ethyl methacrylate:
Fireproof.
Separated from strong oxidants.
Cool.
Keep in the dark.
Store only if stabilized.
Storage Conditions of Ethyl methacrylate:
Before entering confined space where this chemical may be present, check to make sure that an explosive concentration does not exist.
Store in tightly closed containers in a cool, well ventilated area away from oxidizers (such as perchlorates, peroxides, permanganates, chlorates, and nitrates).
Sources of ignition, such as smoking and open flames, are prohibited where ethyl methacrylate is handled, used, or stored.
Metal containers involving the transfer of 5 gallons or more of ethyl methacrylate should be grounded and bonded.
Drums must be equipped with self-closing valves, pressure vacuum bungs, and flame arresters.
Use only nonsparking tools and equipment, especially when opening and closing containers of ethyl methacrylate.
Storage temp: below 38 °C (100 °F).
Acrylic resin monomers, such as ethyl methacrylate polymerize readily in the presence of light, heat, or catalysts such as benzoyl peroxide.
They must be stored with inhibitors present to avoid spontaneous & explosive polymerization.
The effectiveness of phenolic inhibitors, eg, monomethyl ether of hydroquinone & hydroquinone, depends on the presence of oxygen.
Monomers inhibited with these materials must be stored in air rather than in an inert atmosphere.
Contamination must be avoided; eg, moisture may cause rust-initiated polymerization.
Temperatures during storage must be kept low to minimize formation of peroxides & other oxidation products.
In general, the methacrylate monomers should not be stored for longer than 1 year.
The methacrylic esters may be stored in mild steel (low carbon), stainless steel, or aluminum.
Methods of Manufacturing of Ethyl methacrylate:
Reaction of methacrylic acid or methyl methacrylate with ethyl alcohol in the presence of a mineral acid.
Made by a reaction between ethanol and methyl methacrylate (transesterification).
The catalyst is sodium alcoolate.
Extraction by methanol.
Commercial production of methacrylates, which began in 1933 from acetone cyanohydrin (ACN) involved conversion of acetone cyanohydrin to alpha-hydroxybutyrate ester followed by dehydration to the methacrylate with phosphorus pentachloride (PCl5).
In 1934, a process was patented for converting acetone cyanohydrin to methacrylamide sulfate which is hydrolyzed & esterfied to the methacrylate ester; this process forms the basis for all contemporary commercial methacrylate production.
Properties of Ethyl methacrylate:
Ethyl Methacrylate is a colorless liquid with a melting point below -75"C, a
boiling point of 119"C, and a specific gravity of 0.911.
Ethyl methacrylate has aÖmolecular weight of 114.14, a refractive index (n 25/D) of 1.41 16, and a flash point (OC) of 70°F.
Ethyl Methacrylate has an acrid acrylate odor and is soluble in alcohol and ether.
Ethyl Methacrylate is readily polymerized, and is chemically reactive.
The extent of curing for two Ethyl Methacrylate-based commercial fingernail formulations was determined over intervals ranging from 5 rnin to 24 h.
The formulations used were moderately cross-linked preparations that were cured in sample pans at body temperature (37°C).
Differential scanning calorimetry was used to measure the exotherm created when unreacted monomer began to polymerize.
Negative values were indicative of greater exotherm, and therefore larger amounts of unreacted monomer.
Additionally, the formulations were allowed to cure on fingernails at room temperature (28°C) and particles produced from filing the hardened formulations were analyzed after 45 and 90 rnin of aging, and fingernail clippings were evaluated after 45 min.
After 5 min of curing, both formulations had significant exotherm values (-44.93 J/g and - 83.05 J/g) that were used as conservative estimates of the 50% monomer conversion value.
Using these values, Ethyl methacrylate was calculated that the relative percentage of unreacted monomer after 1 hr at 37°C was <1.0% for both formulations.
The average residual monomer content for the fingernail filings was <2% at 45 min, and <1% at 90 min.
The slower polymerization observed here was attributed to the cooler temperature (28°C) at which the formulations were allowed to cure.
This was also observed with the fingernail clippings, in which < l%
monomer was found in both clipping samples at 45 min.
As a follow up to this study, Schoon measured the unreacted monomer content of the same two fingernail samples cured at 30°C.
Both samples were cured in aluminum pans at 30"C, and exotherm measurements were taken at 5 rnin and 1 and 4 h.
Using the 5-min exotherm values as the estimated 50% monomer conversion values, residual monomer content was calculated to be 0.6% at 1 h.
At 4 h, the residual monomer content fell below detection levels.
A profile of the cure temperature of the two Ethyl Methacrylate fingernail formulations was also conducted.
Each formulation, stored at 23"C, was applied at 25°C to a fingernail fitted to precision fine wire thermocouples.
Temperatures were recorded using an analog-to-digital data acquisition board, cold junction signal conditioner, and a 486/66 MHz computer.
Immediately following the first bead application of both products at the dorsal tip of the nail, cooling was measured.
When the formulations were applied directly over the thermocouple, the temperature dropped from 35.5 to 29.2”C, which was attributed to the lower temperatures of the formulations.
Two additional drops in temperature were observed when the second and third beads of each formulation were applied to the nail.
The temperature began to rise within 1 min following the final bead application.
This warming trend lasted for -3 min for one formulation and an additional 20 s for the other formulation.
Maximum exotherm temperatures of 41.8 and 43.0”C were measured, which returned to a baseline temperature of 353°C.
Five minutes after curing, the nail enhancements were filed, which produced a small amount of frictional heat.
However, filing with a less abrasive “finishing” file produced an overall cooling effect, which the investigator attributed to lower generation of heat and higher thermal conductivity of the file.
Temperatures returned to baseline levels once the finishing process was completed.
The mean temperature over the 40-min test period was 35.1 and 35.2”C for the two formulations.
The investigator noted that table lamps were not used during this experiment, but are commonly used during salon applications.
Therefore, mean temperatures recorded in this study are probably lower than would occur under normal conditions of use.
Sensitization and Cross-Sensitivity
Ethyl Methacrylate was tested for sensitization potential in the guinea pig maximization test.
Groups of ten Duncan Hartley guinea pigs were administered three pairs of intradermal injections of 0.1 ml Freund’s complete adjuvant (FCA), Ethyl Methacrylate in peanut oil, and Ethyl Methacrylate in FCA in their backs.
The concentrations of Ethyl Methacrylate tested were 0.17, 0.50, and 1.50 M.
On day 7, an occlusive patch containing 1 M Ethyl Methacrylate was applied to the site of the injections for 48 h.
After a 2-week non-treatment period, the right flank of each guinea pig was shaved and 3 M undiluted Ethyl Methacrylate was applied under occlusive patches for 24 h.
The sites were scored at 24 and 48 h.
On day 35, 3 M undiluted Ethyl Methacrylate was applied to the shaved left flank of each guinea pig and left uncovered.
Readings were taken after 24 and 48 h.
A control group of six guinea pigs received the same treatment, except that only the vehicle was used in the applications.
There was no evidence of sensitization in the guinea pigs induced with 0.17 M Ethyl Methacrylate.
One guinea pig induced with 0.50 M Ethyl Methacrylate had evidence of sensitization after treatment on day 35 and one positive reaction was observed after both the 21- and 35-day treatments among the guinea pigs induced with 1 SO M Ethyl Methacrylate.
When this experiment was repeated using a 0.5 M induction concentration on day 0, one of 10 guinea pigs reacted after both the 21- and 35-day applications.
Ethyl Methacrylate was also tested with Freund’s complete adjuvant.
Six guinea pigs were induced with intradermal injections of 5 X 0.5 M Ethyl Methacrylate in FCA and water on days 0,2,4,7, and 9.
On days 21 and 35, the shaved right and left flanks, respectively, were treated topically with 3 M undiluted Ethyl Methacrylate.
The sites were left uncovered and readings were taken 24 and 48 h following each of these treatments.
Two of the six guinea pigs had positive reactions following both the 21- and 35-day treatments.
That suggested the sensitization potential of Ethyl Methacrylate was dependent upon the vehicle of administration and that mutual cross-sensitivity exists between monomers of methacrylic acid.
Guinea pigs were injected with 0.1 ml of Freund’s complete adjuvant with heatkilled Mycobacterium butyricum into each foot pad (total volume 0.4 ml; total amount of M. butyricum 100 pg).
One group of 25 animals was treated with topical applications of 0.03 ml of Ethyl Methacrylate in ethanol on days 0,2, and 5.
When the first challenge with 2 and 5% Ethyl Methacrylate in ethanol was administered on day 25, no sensitization was observed 72 h following the challenge application.
The animals received a second challenge on day 60 with either a topical dose of 10% Ethyl Methacrylate in olive oil or an intradermal dose of Ethyl Methacrylate in saline (0.01 and 0.1 plhite).
The Ethyl Methacrylate in olive oil produced severe sensitization reactions.
However, the intradermal dose of Ethyl Methacrylate in saline did not evoke any responses.
A third challenge on day 122 with 0.4 and 2% Ethyl Methacrylate in olive oil caused sensitization within 72 h.
The researchers suggested that Ethyl Methacrylate in ethanol evaporated.
Before Ethyl methacrylate could elicit a response.
Another group of nine guinea pigs was initially treated with 0.0077 ml of Ethyl Methacrylate in olive oil on day 60 (as controls) and was challenged with 2 and 5% Ethyl Methacrylate in olive oil on day 95.
Positive reactions were observed in all of the animals after 72 h.
When the guinea pigs from both groups were challenged a second or fourth time with Ethyl Methacrylate and either 1% methyl methacrylate or 1% butyl methacrylate, strong cross-sensitivity was observed.
In another study, three guinea pigs sensitized to either 1 or 4 M Ethyl Methacrylate were tested for cross-reactivity with several acrylic monomers.
The animals, sensitized in the Freund’s Adjuvant Test or the Guinea Pig Maximization Test, were challenged on one flank with acrylates, methacrylates, diacrylates, and dimethacrylates (0.025 ml) 2 weeks after completing the tests.
A second challenge with the monomers was conducted 2 weeks later on the other flank.
Readings of the test sites were conducted 24 and 48 h following application.
After the last challenge to test cross reactions, the guinea pigs were also challenged with Ethyl Methacrylate.
Some of the animals had cross-reactions with acrylates, methacrylates, and dimethacrylates.
However, these reactions were only to specific monomers and usually involved only one guinea pig.
None of the guinea pigs reacted to the diacrylate.
Metabolism/Metabolites of Ethyl methacrylate:
Methyl methacrylate and other short chain alkyl-methacrylate esters are initially hydrolyzed by non-specific carboxylesterases to methacrylic acid and the structurally corresponding alcohol in several tissues.
Methacrylate esters can conjugate with glutathione (GSH) in vitro, although they show a low reactivity, since the addition of a nucleophile at the double bond is hindered by the alpha-methyl side-group
Hence, ester hydrolysis is considered to be the major metabolic pathway for alkyl-methacrylate esters, with GSH conjugation only playing a minor role in their metabolism, and then possibly only when very high tissue concentrations are achieved.
Acrylates and methacrylates are detoxified predominantly via conjugation with glutathione via the Michael addition reaction or glutathione-S-transferase.
They are also likely to be hydrolyzed via carboxylesterases.
The lower molecular weight esters are rapidly metabolized and eliminated, therefore, will not likely cause cumulative toxicity.
Small quantities of methacrylates may readily be metabolized by saponification into the alcohol & methacrylic acid.
The latter may form an acetyl CoA derivative, which then enters the normal lipid metabolism.
Polymerization of Ethyl methacrylate:
Heat can cause a violent polymerization reaction with rapid release of energy.
Acrylic resin monomers, such as ethyl methacrylate polymerize readily in the presence of light, heat, or catalysts such as benzoyl peroxide.
They must contain inhibitors to avoid spontaneous & explosive polymerization.

Impurities of Ethyl methacrylate:
Typical impurities include Methyl Acrylic Acid (MAA) (CAS 79-41-4) or MMA (CAS 80-62-6) (depending whether the direct esterification or trans-esterification route is used), the unreacted alcohol and water.
In the case of EMA produced by the trans-esterification route, methyl- and ethyl acetate are present as minor impurities rather than ethanol.
Environmental issues and health hazards of Ethyl methacrylate:
The acute toxicity of the related butyl methacrylate is the LD50 is 20 g/kg (oral, rat).
Acrylate esters irritate the eyes and can cause blindness.
First Aid of Ethyl methacrylate:
EYES: First check the victim for contact lenses and remove if present.
Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center.
Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician.
IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.
SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing.
Gently wash all affected skin areas thoroughly with soap and water.
If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment.
INHALATION: IMMEDIATELY leave the contaminated area; take deep breaths of fresh air.
If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital.
Provide proper respiratory protection to rescuers entering an unknown atmosphere.
Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used; if not available, use a level of protection greater than or equal to that advised under Protective Clothing.
INGESTION: DO NOT INDUCE VOMITING.
If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center.
Be prepared to transport the victim to a hospital if advised by a physician.
If the victim is convulsing or unconscious, do not give anything by mouth, ensure that the victim's airway is open and lay the victim on his/her side with the head lower than the body.
DO NOT INDUCE VOMITING.
IMMEDIATELY transport the victim to a hospital.
Fire Fighting of Ethyl methacrylate:
CAUTION: All these products have a very low flash point: Use of water spray when fighting fire may be inefficient.
SMALL FIRE: Dry chemical, CO2, water spray or regular foam.
LARGE FIRE: Water spray, fog or regular foam.
Do not use straight streams.
Move containers from fire area if you can do Ethyl methacrylate without risk.
FIRE INVOLVING TANKS OR CAR/TRAILER LOADS: Fight fire from maximum distance or use unmanned hose holders or monitor nozzles.
Cool containers with flooding quantities of water until well after fire is out.
Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank.
ALWAYS stay away from tanks engulfed in fire.
For massive fire, use unmanned hose holders or monitor nozzles; if this is impossible, withdraw from area and let fire burn.
Fire Fighting Procedures of Ethyl methacrylate:
Use dry chemical, carbon dioxide, or alcohol foam extinguishers.
Vapors are heavier than air and will collect in low areas.
Vapors may travel long distances to ignition sources and flashback.
Vapors in confined areas may explode when exposed to fire.
Containers may explode in fire.
Storage containers and parts of containers may rocket great distances, in many directions.
If material or contaminated runoff enters waterways, notify downstream users of potentially contaminated waters.
Notify local health and fire officials and pollution control agencies.
From a secure, explosion-proof location, use water spray to cool exposed containers.
If cooling streams are ineffective (venting sound increases in volume and pitch, tank discolors or shows any signs of deforming), withdraw immediately to a secure position.
If material on fire or involved in fire: Do not extinguish fire unless flow can be stopped.
Use water in flooding quantities as fog.
Solid streams of water may spread fire.
Cool all affected containers with flooding quantities of water.
Apply water from as far a distance as possible.
Use foam, dry chemical, or carbond dioxide.
Evacuation: If fire becomes uncontrollable or container is exposed to direct flame, consider evacuation of 1/3 mile radius.
Isolation and Evacuation of Ethyl methacrylate:
As an immediate precautionary measure, isolate spill or leak area for at least 50 meters (150 feet) in all directions.
LARGE SPILL: Consider initial downwind evacuation for at least 300 meters (1000 feet).
FIRE: If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions
Spillage Disposal of Ethyl methacrylate:
Remove all ignition sources.
Evacuate danger area! Consult an expert! Personal protection: chemical protection suit and filter respirator for organic gases and vapours adapted to the airborne concentration of the substance.
Ventilation.
Collect leaking liquid in sealable containers.
Absorb remaining liquid in sand or inert absorbent.
Then store and dispose of according to local regulations.
Cleanup Methods of Ethyl methacrylate:
Wastewater from contaminant suppression, cleaning of protective clothing/equipment, or contaminated sites should be contained and evaluated for subject chemical or decomposition product concentrations.
Concentrations shall be lower than applicable environmental discharge or disposal criteria.
Alternatively, pretreatment and/or discharge to a permitted wastewater treatment facility is acceptable only after review by the governing authority and assurance that "pass through" violations will not occur.
Due consideration shall be given to remediation worker exposure (inhalation, dermal and ingestion) as well as fate during treatment, transfer and disposal.
If Ethyl methacrylate is not practicable to manage the chemical in this fashion, Ethyl methacrylate must be evaluated in accordance with EPA 40 CFR Part 261, specifically Subpart B, in order to determine the appropriate local, state and federal requirements for disposal.
Spill Handling: Evacuate and restrict persons not wearing protective equipment from area of spill or leak until cleanup is complete.
Remove all ignition sources.
Establish forced ventilation to keep levels below explosive limit.
Absorb liquids in vermiculite, dry sand, earth, peat, carbon, or a similar material and deposit in sealed containers.
Keep ethyl methacrylate out of a confined space, such as a sewer, because of the possibility of an explosion, unless the sewer is designed to prevent the build-up of explosive concentrations.
Ethyl methacrylate may be necessary to contain and dispose of this chemical as a hazardous waste.
If material or contaminated runoff enters waterways, notify downstream users of potentially contaminated waters.
Disposal Methods of Ethyl methacrylate:
Generators of waste (equal to or greater than 100 kg/mo) containing this contaminant, EPA hazardous waste number U118, must conform with USEPA regulations in storage, transportation, treatment and disposal of waste.
A good candidate for fluidized bed incineration at a temperature range of 450 to 980 °C and residence times of seconds for liquids and gases, and longer for solids.
A good candidate for rotary kiln incineration at a temperature range of 820 to 1,600 °C and residence times of seconds for liquids and gases, and hours for solids.
Preventive Measures of Ethyl methacrylate:
The scientific literature for the use of contact lenses by industrial workers is inconsistent.
The benefits or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses.
However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye.
In those specific cases, contact lenses should not be worn.
In any event, the usual eye protection equipment should be worn even when contact lenses are in place.
Contaminated protective clothing should be segregated in a manner that results in no direct personal contact by personnel who handle, dispose of, or clean the clothing.
Quality assurance procedures to confirm the efficacy of the cleaning procedures should be implemented prior to the decontaminated protective clothing being returned for reuse by the workers.
Contaminated clothing (including shoes/socks) should not be taken home at end of shift, but should remain at employee's place of work for cleaning.
Local exhaust ventilation should be applied wherever there is an incidence of point source emissions or dispersion of regulated contaminants in the work area.
Ventilation control of the contaminant as close to Ethyl methacrylate point of generation is both the most economical and safest method to minimize personnel exposure to airborne contaminants.
Ensure that the local ventilation moves the contaminant away from the worker.
Inhalation & skin contact should be avoided.
