The acute toxicity of methyl methacrylate is low. The effect observed most frequently at lowest concentration after repeated inhalation exposure to methyl methacrylate is irritation of the nasal cavity. Effects on the kidney and liver at higher concentrations have also been reported.
Is methacrylate polymer safe?
Methacrylates are generally of low toxicity, have not been found to damage reproduction or harm the unborn child, and studies in workers exposed to methacrylates for more than 30 years indicate that there is no increased risk of developing cancer due to occupational exposure.
What are the side effects of methacrylic acid?
* Methacrylic Acid is a HIGHLY CORROSIVE CHEMICAL and contact can severely irritate and burn the skin and eyes with possible eye damage. * Breathing Methacrylic Acid can irritate the nose and throat. High levels can affect the lungs causing coughing, wheezing and/or shortness of breath.

EPA considers methyl methacrylate not likely to be carcinogenic to humans.
What happens if you inhale methyl methacrylate?
* Breathing Methyl Methacrylate can irritate the lungs causing coughing and/or shortness of breath. Higher exposures can cause a build-up of fluid in the lungs (pulmonary edema), a medical emergency, with severe shortness of breath.
Can you be allergic to methyl methacrylate?
Your patch test result indicates that you have a contact allergy to methyl methacrylate. This contact allergy may cause your skin to react when it is exposed to this substance although it may take several days for the symptoms to appear. Typical symptoms include redness, swelling, itching and fluid-filled blisters.
Is MMA hazardous?
How Dangerous is It? MMA is about as dangerous as any other full contact sport. Like in sports such as hockey and football MMA athletes are prone to a wide variety of injuries ranging from mild sprains to brain injuries such as concussions. Just like in other sports, not every athlete will sustain a major injury.
What is the pH of methacrylic acid?
Methacrylic acid = 0.20 M ; initiator = 1-22 x 10-3 M ; ethanol = 4 m1/100 ml solution; pH = 4; t = 61.0″C.
Is PMMA carcinogenic?
PMMA elutes MMA during its setting phase. The reaction between the monomer liquid and the polymer powder is exothermic in nature. Animal studies have proven that monomers can lead to carcinogenesis. However, PMMA is routinely used as a bone cement in orthopedics and as denture materials in dentistry presently.
How common is methacrylate allergy?

Methyl methacrylate and ethyl acrylate are now part of the North American Standard Series in the baseline series of patch test allergens and have identified many cases of acrylate allergy.
What are the side effects of methyl methacrylate exposure?
* High exposure can cause dizziness, irritability, difficulty with concentration and reduced memory. * Methyl Methacrylate may cause a skin allergy. If allergy develops, very low future exposure can cause itching and a skin rash.
