This study investigated the effects of a methacrylic acid (MAA) copolymer on cells because these polymers have been shown to promote vascular regenerative responses in vivo (9, 10), but the mechanism behind this response is unknown (11–13).
2-hydroxyethyl methacrylate (HEMA) is a monomer based on methacrylic acid (MAA) used to produce biomaterials such as dental adhesive and composite resins . The process of polymerization, which is run in situ, is always incomplete, resulting in the presence of free monomers in the oral cavity [ 2 ].
Thus, treatments that alter macrophage phenotypes may be beneficial for resolution of muscle injuries. In the skin, materials based on methacrylic acid (MAA) bias macrophages towards a "pro-regenerative" phenotype through an IGF-1 mediated pathway [19,20].

Methacrylic acid (MA) is a strong irritant and is corrosive because of its strong acidity. It can also rapidly penetrate gloves and skin, causing allergic reactions. This monomer is, therefore, seldom added to adhesives.
Methacrylic acid, abbreviated MAA, is an organic compound. This colorless, viscous liquid is a carboxylic acid with an acrid unpleasant odor. It is soluble in warm water and miscible with most organic solvents. Methacrylic acid is produced industrially on a large scale as a precursor to its esters, especially methyl methacrylate and poly. MAA occurs naturally in small amounts in the oil of Roman chamomile.

Excerpt from ERG Guide 153P [Substances - Toxic and/or Corrosive (Combustible)]: As an immediate precautionary measure, isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids.
* Breathing Methacrylic Acid can irritate the nose and throat. High levels can affect the lungs causing coughing, wheezing and/or shortness of breath. * Methacrylic Acid may cause a skin allergy. If allergy develops, very low future exposure can cause itching and a skin rash. * Methacrylic Acid may affect the kidneys.

Eye contact with methacrylic acid may cause severe irritation and permanent eye injury. Skin contact can cause severe irritation and tissue damage. Although the oral toxicity of methacrylic acid is considered low, swallowing is likely to result in irritation and/or chemical burns to the mouth and throat.
treatment with tert-butyl hydroperoxide (TBHP) and sodium formaldehyde sulfoxylate (SFS) on the properties of the latexes produced by emulsion copolymerization of styrene (Sty) with n-butyl acrylate (BuA) and methacrylic acid (MAA), with initiator introduced in a shot process. The study intends to
With MAA as an aqueous solution of 4.8 % (= approx. 150 mg/kg) no skin irritation was observed after single or repeated dermal exposure up to 21 d (treatment interval 2-3 days, 9 exposures). When methacrylic acid was diluted in acetone and applied similarly, concentration-related irritation was observed.

OECD SIDS METHACRYLIC ACID UNEP Publications 3 Environment Approximately 45 000 t/a of methacrylic acid (MAA) are assumed to be available on the European market. MAA is used as an internal and external intermediate in the chemical industry for the production of methacrylic acid esters and as a co-monomer in different kinds of polymers.
