4.2 Most important symptoms/effects, acute and delayedInhalation of the vapor or mist can cause irritation to the upper respiratory tract. Asthmatic symptoms have been reported. Extremely irritating; may cause permanent eye injury. Corrosive; will cause severe skin damage with burns and blistering. Ingestion may cause damage to the mucous membranes and gastrointestinal tract. (USCG, 1999)
4.3 Indication of immediate medical attention and special treatment needed, if necessaryImmediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR if necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on the left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Organic bases/Amines and related compounds/

10.2 Chemical stabilityStable under recommended storage conditions.
10.3 Possibility of hazardous reactionsFlammable liquid when exposed to heat or flame; can react vigorously with oxidizing materials. Ignites spontaneously in contact with cellulose nitrate of high surface area.The vapour is heavier than air.DIMETHYLAMINOETHANOL is an organic compound with both amine and alcohol substituents. 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. This compound may react vigorously with oxidizing materials.

12.Ecological information 12.1 Toxicity- Toxicity to fish: no data available
- Toxicity to daphnia and other aquatic invertebrates: no data available
- Toxicity to algae: no data available
- Toxicity to microorganisms: no data available
AEROBIC: 2-Dimethylaminoethanol, present at 100 mg/L, reached 60.5% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test which classified the compound as readily biodegradable(1). A static test using a non adapted activated sludge inoculum measured a 2-dimethylaminoethanol degradation of >90% in 13 days(2).
12.3 Bioaccumulative potentialAn estimated BCF of 3 was calculated in fish for 2-dimethylaminoethanol(SRC), using a log Kow of -0.55(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
12.4 Mobility in soilUsing a structure estimation method based on molecular connectivity indices(1), the Koc of 2-dimethylaminoethanol can be estimated to be 1(SRC). According to a classification scheme(2), this estimated Koc value suggests that 2-dimethylaminoethanol is expected to have very high mobility in soil. The pKa of 2-dimethylaminoethanol is 9.3(3). At pH 8.2, 20% will be the free amine. Thus, this compound will exist almost entirely in the cation form in the environment and cations generally adsorb to organic carbon and clay more strongly than their neutral counterparts(4). As a result, 2-dimethylaminoethanol may have greater adsorption and less mobility than its estimated Koc value indicates.
12.5 Other adverse effectsno data available
13.Disposal considerations 13.1 Disposal methods ProductThe material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Contaminated packagingContainers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
