Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Guidance on Safe Use
Administrative data
First-aid measures
INHALATION
Move the exposed person to fresh air at once. Get medical attention if symptoms persist.
INGESTION
Wash out mouth with water, provided person is conscious. Get medical attention immediately.
SKIN CONTACT
Remove contaminated clothing and wash skin with soap and plenty of running water. Get medical attention if symptoms persist.
EYE CONTACT
Rinse immediately eye with plenty of low pressure water for at least 15 minutes.
Remove any contact lenses. Get medical attention immediately.
Fire-fighting measures
EXTINGUISHING MEDIA
To extinguish fire use water spray, dry powder, carbon dioxide, or foam.
SPECIAL FIRE FIGHTING PROCEDURES
Prevent run-off water from entering the sewer system.
UNUSUAL FIRE & EXPLOSION HAZARDS
None known.
SPECIFIC HAZARDS
By fire toxic gases may be formed (Cox, NOx).
PROTECTIVE MEASURES IN FIRE
Self contained breathing apparatus and full protective clothing.
Accidental release measures
PERSONAL PRECAUTIONS
See section on exposure controls/personal protection
ENVIRONMENTAL PRECAUTIONS
Take precautionary measures against discharges into the environment.
SPILL CLEAN UP METHODS
Collect spilled material without creating dust, then place into a suitable closed container for disposal as chemical waste.
Handling and storage
USAGE PRECAUTIONS
Avoid contact with eyes and skin.
Wash thoroughly after handling and before eating, drinking or smoking.
STORAGE PRECAUTIONS
To protect product quality, store in sealed container in a cool place and out of direct sunlight.

Exposure controls / personal protection
EXPOSURE LIMITS
WHO (1993): international drink water guideline for nitrilotriacetic acid: 200 microgram/L
USE LIMITS
See below.
PNECs (see also section 12):
aqua-freshwater: 0.69 mg/L
aqua-marine water: 0.069 mg/L
aqua-intermittent: 6.9 mg/L
sewage treatment plant: 400 mg/L
soil 0.73 mg/kg dw
There are neither monitoring data for sediments nor toxicity tests with benthic organisms available. The NTA concentration can be modelled using the equilibrium partitioning method. A risk assessment for sediments will then lead to identical PEC/PNEC ratios like for the aquatic compartment. Because of the low partitioning coefficients, no accumulation in sediments is expected. Thus an assessment of this sub-compartment is not necessary.
DNELs:
The main derived long-term DNELs for systemic effects are:
Workers General population
Oral not relevant 0.11 mg/kg bw/day
Dermal 0.37 mg/kg bw/day 0.185 mg/kg bw/day
Inhalation 0.2 mg/m3/day 0.048 mg/m3/day
The CHESAR v2.3.0 model for this substance shows for indoor industrial activities taking more than 4 hours/day, with local exhaust ventilation present (and running), provided workers wear gloves with at least 90% protection (chemically resistant gloves conforming to EN374 with basic employee training) the following occupational exposures:
Inhalation dermal RCR RCR RCR
mg/m3 mg/kg/day inhalation dermal total
PROC4 0.035 0.069 0.175 0.185 0.36
Use in batch and other processes (synthesis) where opportunity for exposure arises
PROC5 0.035 0.137 0.175 0.37 0.545

Note:
• Dustiness of the material has been set at low
• For workers a good general ventilation (3-5 air changes per hour) has been assumed; and an advanced occupational health and safety management system
• The substance is classified as an eye irritant category 2 with H319 (causes serious eye irritation). Wear approved safety goggles classified under EN 166:2001.
The CHESAR v2.3.0 model for this substance shows for indoor professional activities, with local exhaust ventilation present (and running), provided professional users wear gloves with at least 90% protection (chemically resistant gloves conforming to EN374 with basic employee training) the following occupational exposures:
PROC11 0.017 0.257 0.084 0.695 0.779
