... Hazard is the generation of considerable exothermic heat in some of the reactions, so that high pressures & temp may develop. This danger ... should be borne in mind when designing plant. Awareness of the dangers and of good engineering design are essential to safety. Employees should be instructed about the necessity of cleansing the skin if it is contaminated by materials which are irritants or skin-absorbed. With careful design, however, and complete enclosure of those processes where toxic chemicals or intermediates occur, dangerous exposures can be avoided. /Acrylic acid & derivatives/

SRP: 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.

2-DIMETHYLAMINOETHYL METHACRYLATE is both an amine and an acrylate ester. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides.

IDENTIFICATION AND USE: N,N-dimethylaminoethyl methacrylate is a colorless liquid with amine-like odor.It is used in binders for coatings, textile chemicals, dispersing agents for nonaqueous systems, antistatic agents, stabilizers for chlorinated polymers, ion exchange resins, emulsifying agents, cationic precipitating agents. It is also used in dental materials, antithrombogenic prosthetics, experimental use in slow-release capsules, in cosmetics. More recently, It is also used in nanoparticles for gene delivery and drug delivery. HUMAN EXPOSURE AND TOXICITY: pH-Sensitive poly(N,N-dimethylaminoethyl methacrylate (DMAEMA)/2-hydroxyethyl methacrylate (HEMA)) nanoparticles were not cytotoxic. ANIMAL STUDIES: Dimethylaminoethyl methacrylate decreased the heart rate and force of contraction of isolated, perfused rabbit heart when added to perfusing liquid. Dimethylaminoethyl methacrylate was strongly irritating to skin of guinea pigs and conjunctiva of rabbits. When administered by gastric gavage to rabbits, dimethylaminoethyl methacrylate initially suppressed brain electrical activity and then induced clonic-tonic spasms. In dogs it produced hypertensive effect following iv administration. The toxicity of 6 acrylates and 6 methacrylates, including N,N-dimethylaminoethyl methacrylate, was determined in rats and fish. All the esters were less toxic than acrylamide and acrylonitrile.

/OTHER TOXICITY INFORMATION/ pH-Sensitive poly(N,N-dimethylaminoethyl methacrylate (DMAEMA)/2-hydroxyethyl methacrylate (HEMA)) nanoparticles were prepared for the triggered release of paclitaxel within a tumor microenvironment. Tumors exhibit a lower extracellular pH than normal tissues. We show that paclitaxel release from DMAEMA/HEMA particles can be actively triggered by small, physiological changes in pH (within 0.2-0.6 pH units). Monodispersed nanoparticles were synthesized by forming an O/W emulsion followed by photopolymerization. Particles were characterized by transmission electron microscopy, dynamic light scattering, electrophoresis, and cytotoxicity. High release rates and swelling ratios are achieved at low pH, low crosslinking density, and high content of DMAEMA. Paclitaxel release is limited to 9% of the payload at pH 7.4 after a 2-hr incubation at 37 degrees C. After adjusting to pH 6.8, 25% of the payload is released within 2 hr. Cell viability studies indicate that pH-sensitive DMAEMA/HEMA nanoparticles are not cytotoxic and may be used as an efficient, feedback-regulated drug delivery carrier. /Poly(N,N-dimethylaminoethyl methacrylate/

/LABORATORY ANIMALS: Acute Exposure/ Dimethylaminoethyl methacrylate decreased the heart rate and force of contraction of isolated, perfused rabbit heart when added to perfusing liquid at concentrations of 1:1000, 1:10,000 or 1:100,000.

/LABORATORY ANIMALS: Acute Exposure/ 1,2-Diethylaminoethyl methacrylate and 2-dimethylaminoethyl methacrylate were strongly irritating to skin of guinea pigs & conjunctiva of rabbits. Diisopropylaminoethyl methacrylate was nonirritating.

/LABORATORY ANIMALS: Acute Exposure/ When administered by gastric gavage to rabbits, dimethylaminoethyl methacrylate and diethylaminoethyl methacrylate initially suppressed brain electrical activity and then induced clonic-tonic spasms.

/LABORATORY ANIMALS: Acute Exposure/ Methacrylic acid admin iv incr respiratory rate, decr heart rate, and produced electrocardiogram changes in anesthetized dogs. Methacrylic acid, methyl, n-propyl, n-butyl, isobutyl, and hydroxyethyl methacrylates produced a biphasic response, an abrupt fall in blood pressure followed by a secondary rise. 2-Ethylhexyl, isodecyl, lauryl, and tert-butylaminoethyl methacrylates produced only a hypotensive effect. Dimethylaminoethylmethacrylate produced only a hypertensive effect.

N,N-Dimethylaminoethyl methacrylate's production and use as an intermediate for chemical synthesis and as a monomer in the production of a variety of polymers for water treatment, paper agents, paints, coatings and personal care products may result in its release to the environment through various waste streams. If released to air, an estimated vapor pressure of 0.72 mm Hg at 25 °C indicates N,N-dimethylaminoethyl methacrylate will exist solely as a vapor in the atmosphere. Vapor-phase N,N-dimethylaminoethyl methacrylate will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 3.9 hours. Vapor-phase N,N-dimethylaminoethyl methacrylate will also be degraded in the atmosphere by reaction with ozone and nitrate radicals; the half-lives for these reactions in air is estimated to be 24 hours and 6.5 days respectively. If released to soil, N,N-dimethylaminoethyl methacrylate is expected to have very high mobility based upon an estimated Koc of 20. The pKa of N,N-dimethylaminoethyl methacrylate is 8.44, indicating that this compound will exist mostly in the cation in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts. Volatilization from moist soil surfaces is not expected to be an important fate process based upon an estimated Henry's Law constant of 1.4X10-7 atm-cu m/mole. N,N-Dimethylaminoethyl methacrylate may volatilize from dry soil surfaces based upon its estimated vapor pressure. Utilizing the OECD 301E test, 95.3% degradation was reached in 2 weeks indicating that biodegradation is an important environmental fate process in soil and water. N,N-Dimethylaminoethyl methacrylate may degrade via abiotic hydrolysis in moist alkaline and neutral soils. If released into water, N,N-dimethylaminoethyl methacrylate is not expected to adsorb to suspended solids and sediment based upon the estimated Koc. Volatilization from water surfaces is not expected to be an important fate process based upon this compound's estimated Henry's Law constant. An estimated BCF of 2.6 suggests the potential for bioconcentration in aquatic organisms is low. The hydrolysis half-life of N,N-dimethylaminoethyl methacrylate at 25 °C was determined to be 4.54 days and 3.31 hours at pH 7 and pH 9, respectively; the compound is stable to hydrolysis at pH 4. N,N-Dimethylaminoethyl methacrylate is an olefin and olefins in surface waters exposed to sunlight have a half-life on of 25 days. Occupational exposure to N,N-dimethylaminoethyl methacrylate may occur through inhalation and dermal contact with this compound at workplaces where N,N-dimethylaminoethyl methacrylate is produced or used(SRC). The general population may be exposed to N,N-dimethylaminoethyl methacrylate via dermal contact with consumer products containing polymers made with the compound and resulting migration of residual monomer from the polymer matrix. (SRC)

N,N-Dimethylaminoethyl methacrylate's production and use as an intermediate for chemical synthesis and as a monomer in the production of a variety of polymers for water treatment, paper agents, paints, coatings and personal care products(1,2) may result in its release to the environment through various waste streams(SRC).

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 20(SRC), determined from a structure estimation method(2), indicates that N,N-dimethylaminoethyl methacrylate is expected to have very high mobility in soil(SRC).
