Other Preventative Measures
SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit 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.

  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: Triethanolamine, present at 50 ppm, was biodegraded 70% ThOD (theoretical oxygen demand) in 10 days in a river die-away test using acclimated Kanawha River water as seed and sewage as inoculum(1). In a BOD test in water using a sewage inoculum, triethanolamine added at an initial concentration 2.5 ppm and run for 5, 10, 15 and 20 days exhibited 0, 0.8, 3.5 and 6.8% ThOD, respectively(2). Another BOD test in water using sewage inoculum incubated for 20 days resulted in 66% ThOD for triethanolamine(3). Using synthetic sea water and sewage inoculum, a 20 day run showed 69% ThOD for triethanolamine(3). Using effluent from a biological sanitary waste treatment plant as an inoculum, triethanolamine degradation was 5% ThOD (unadapted) and 28% ThOD (adapted) in a 5 day test(4). Triethanolamine, present at 500 ppm, added to BOD water with an activated sludge inoculum and acclimated for 15 days resulted in 22% ThOD after a 10 day test period(5).

12.3 Bioaccumulative potential

BCFs of <0.4 and <3.9 were reported using carp (Cyprinus carpio) which were exposed to respective concentrations of 2.5 and 25 ppm of triethanolamine over a 6-week period(1). According to a classification scheme(2), these BCFs suggest bioconcentration in aquatic organisms is low.

12.4 Mobility in soil

Using a structure estimation method based on molecular connectivity indices(1), the Koc of triethanolamine can be estimated to be 10(SRC). According to a classification scheme(2), this estimated Koc value suggests that triethanolamine is expected to have very high mobility in soil. The pKa of triethanolamine is 7.76(3), indicating that this compound will partially exist in cation form in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4).

12.5 Other adverse effects

no data available

13.Disposal considerations

13.1 Disposal methods

Product

The 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.
