4. Human Health Safety Assessment
Consumer: The exposure to LATEMUL 2F is at safe levels.
Worker: The repeated exposure of LATEMUL 2F does not cause any toxic effects.
Effect Assessment

ResultNo acute toxicity after oral/ dermal exposurein practical use.
The substance does not cause damage toany organs following single exposure.
Undiluted substance causes skin irritation
Causes serious eye damage.
Based on the available data, unlikely tocause allergic skin reaction.
Unlikely to cause any toxic effects throughprolonged or repeated oral exposure inpractical use.
Based on the available data, unlikely tocause genetic defects.
Based on the available data, unlikely tocause cancer.
Based on the available data, unlikely to bedamaging to fertility or the unborn child.

5. Environmental Safety Assessment
The test results with fish, aquatic invertebrates and algae suggest that LATEMUL 2F could
cause a toxicity to aquatic organisms. It also could cause harmfulness to aquatic organisms
with long lasting effects. However, LATEMUL 2F is unlikely to persist in the environment
because of showing the readily biodegradation. LATEMUL 2F does not bioaccumulate in thefood chain.

Effect Assessment

ResultAquatic Toxicity

Based on the available data, likely to cause acutetoxicity to aquatic organisms and harmful to aquatic life
with long lasting effects.

Biodegradation

Readily biodegradable.

PBT/ vPvB conclusion*

Not persistent in the environment, not bioaccumulatingin organisms and not toxic nor very persistent and very
bioaccumulating.

*PBT=Persistent, Bioaccumulative and Toxic
vPvB=Very Persistent and Very Bioaccumulative

6. ExposureConsumer
The consumer can come into contact with the substance in use of laundry detergents, but theconcentration of LATEMUL 2F in use is below the level which would give rise harmful effectsof concern. When it’s used as the recommended use, consumer should always read productinformation before use and follow the label/ use instructions.
Worker
The exposure can occur either in LATEMUL 2F manufacturing facilities or in the various
industrial facilities when LATEMUL 2F is used. Those workers in industrial operations during
maintenance, sampling, testing, or other procedures could be exposed with LATEMUL 2F.
Only qualified and trained workers handle the undiluted substance. The manufacturing
facilities offer thorough training program for employees and appropriate work processes, aswell as safety equipment (goggles and gloves) in place to present an unnecessary exposure.
Safety showers and eye-wash stations are accessible nearby. Workers are required to be
trained in accordance with the safety measures in the Safety Data Sheet.
Environment
Since this substance is used extensively, it is discharged to waste water treatment plants fromindustrial sites such as manufacturing, preparation, handling, storage and use of thesubstance as well as from consumer households. However, the substance is readily
biodegradable, so that it is removed efficiently in waste water treatment plants. The substanceis biologically degraded in the surface water and is rapidly removed even if it is remainedslightly in the waste water. Hence, the chronic exposure to aquatic organisms of the substanceis unlikely to occur. Furthermore, the substance dose not accumulate in the food chain, so that
there is no concern of human exposure through environmental pathway.

7. Risk management recommendations
When you use the substance, make sure to be measured the adequate ventilation. Always
use appropriate chemical-resistant gloves to protect your hands and skin and always wear
eye protection equipment. Do not eat, drink or smoke where the substance is handled,

processed or stored. Wash hands and skin after contact with the substance. When thesubstance attaches to skin (or hair), take off the contaminated clothes. Wash with a large
amount of water and soap. If the substance gets into your eyes, rinse your eyes thoroughly
for several minutes. If you wear contact lens, and you can take it off easily, take it off andcontinue to rinse your eyes. When it causes your skin irritation or eye irritation, consult doctor(medical diagnosis/therapy).
Waste water containing the substance must be passed the waste water treatment plants inorder to remove the substance. No specific measures are needed, because it is not expected
to be released into the air.

8. Regulatory Information / Classification and Labelling
Under GHS classification chemical substances are classified in hazards for physical properties,
human health and environment. The hazard information for industrial products are transmitted
via specific labels and Safety Data Sheet. GHS offers the standardization for hazard
communication. The subjects who could be assumed to be exposed to the substance, workers,
consumers, transport workers, and emergency responders, can better understand the hazardsof the chemicals in use through the transmission.

Labeling according to UN GHS

UN GHS is the basis for country specific GHS labeling.
LATEMUL 2F may be assigned to following GHS classification.

Classification and Labeling Information
Acute tox. - Oral 4
Skin Irrit. 2
Eye Dam. 1
Aquatic Acute 2
Aquatic Chronic 3

Hazard Statements:

H302: Harmful if swallowed
H315: Causes skin irritation
H318: Causes serious eye damage
H401: Toxic to aquatic life
H412: Harmful to aquatic life with long lasting effects

Signal WordDanger

The laws of manufacturing, sale, transport, use and disposal are different among countries orareas. Details are referred to Safety Data Sheet provided by the supplier.

9. Conclusion
Though LATEMUL 2F is suggested to cause toxicity to aquatic organisms, there is no concern
to the environmental organisms due to the rapid biodegradation of LATEMUL 2F. In thePBT/vPvB assessments for LATEMUL 2F, the substance is not applicable to PBT/vPvB. When
handling the substance, workers should follow the standard safety measures and refer to theSafety Data Sheet. Consumers will usually not come into contact with the substance bulk andthe substance is used diluted products, therefore, it is considered that LATEMUL 2F gives riseno hazardous effects to human health.
