Hexahydro-1,3,5-tris-(-2-hydroxyethyl)-s-triazine

General Statement

Hexahydro-1,3,5-tris-(-2-hydroxyethyl)-s-triazine is a light-yellow liquid. It is a formaldehyde condensate product that is used as an antimicrobial agent in metal working fluids.

We both purchases and produces this chemical. Hexahydro-1,3,5-tris-(-2-hydroxyethyl)-s-triazine is a low to moderate hazard material and the risk of adverse health effects associated with both occupational and consumer use of this chemical is anticipated to be low to moderate. Exposure controls in the workplace serve to prevent adverse health effects to workers. This material is not directly sold to consumers and has no known intended use in consumer products. Therefore, consumer exposure and subsequent risk associated with such exposure is unlikely.

Physical/Chemical Properties

Phys/Chem Safety Assessment

Exposure, Hazard and Safety Assessment

The following section describes possible exposure scenarios and hazards associated with hexahydro-1,3,5-tris-(-2- hydroxyethyl)-s-triazine. The exposure assessment describes both the amount of and the frequency with which a chemical substance reaches a person, a population of people, or the environment. Hazard refers to the inherent properties of a substance that make it capable of causing harm to human health or the environment. The safety assessment reports the possibility of a harmful event arising from exposure to a chemical or physical agent under specific conditions. Just because a substance may possess potentially harmful properties does not mean that it automatically poses a risk. It is not possible to make that determination without understanding the exposure.

Human Health Effects

Human Exposure Assessment

Consumer: Hexahydro-1,3,5-tris-(-2-hydroxyethyl)-s-triazine is widely used as an antimicrobial agent in metal working fluids. This material is not directly sold to consumers and has no known intended use in consumer products. Therefore, consumer exposure is considered to be negligible.

Worker: In industrial settings, hexahydro-1,3,5-tris-(-2-hydroxyethyl)-s-triazine is manufactured and handled in closed processes as much as possible, which ensures that worker exposure is minimized. When there is potential for exposure, such as during loading, unloading, sampling or maintenance operations, exposure to hexahydro-1,3,5-tris-(-2-hydroxyethyl)-s-triazine can be further minimized by the proper use of personal protective equipment.

Human Health Safety Assessment

Consumer: Hexahydro-1,3,5-tris-(-2-hydroxyethyl)-s-triazine is widely used as an antimicrobial agent in metal working fluids. This material is not directly sold to consumers and has no known intended use in consumer products. Therefore, consumer exposure and subsequent risk associated with such exposure is unlikely.

Worker: In industrial settings, hexahydro-1,3,5-tris-(-2-hydroxyethyl)-s-triazine is manufactured and handled primarily in closed processes which limit exposure. Based on the implementation of good manufacturing processes and industrial hygiene practices, the occupational health risk associated with hexahydro-1,3,5-tris-(- 2-hydroxyethyl)-s-triazine is anticipated to be low.

Environmental Effects

Environmental Exposures

Environmental exposure to hexahydro-1,3,5-tris-(-2-hydroxyethyl)-s-triazine is possible via the manufacturing process of this substance or when the substance is used into formulation in industrial settings or during re-packing.

Environmental Hazard Assessment

Hexahydro-1,3,5-tris-(-2-hydroxyethyl)-s-triazine is soluble in water. If released into the aquatic environment, the compound is anticipated to be quickly removed through biodegradation.

Environmental Safety Assessment

Based on the available data, hexahydro-1,3,5-tris-(-2-hydroxyethyl)-s-triazine is considered harmful to aquatic life with long lasting effects. Even acute exposure is considered dangerous to aquatic life. If released to surface waters, significant risk to the aquatic environment is not anticipated as the compound is readily biodegradable and has a low potential for bioaccumulation. Overall, this substance is not considered to be PBT or vPvB.

Risk Management Recommendations

Exposure to hexahydro-1,3,5-tris-(-2-hydroxyethyl)-s-triazine in the workplace can be controlled with sufficient ventilation, proper handling and storage techniques, and the use of appropriate personal protective equipment as recommended in the SDS for this substance. Industrial products that contain significant levels of this material should include necessary safety labeling and provide appropriate handling and disposal methods.

Regulatory Information / Classification and Labeling

Under the Globally Harmonized System for classification and labeling (GHS), substances are classified according to their physical, health, and environmental hazards. The hazards are communicated via specific labels and the (Extended) SDS. GHS attempts to standardize hazard communication so that the intended audience (workers, consumers, transport workers, and emergency responders) can better understand the hazards of the chemicals in use.
