Toxicity for reproduction

No acute toxicity after oral/ dermal exposurein practical use.
The substance does not cause damage toany organs following single exposure.
Based on the available data, unlikely tocause skin/eye irritation.
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 EMASOL S-30V could
cause harmfulness to aquatic organisms. However, EMASOL S-30V is unlikely to persist in
the environment because of showing the readily biodegradation. EMASOL S-30V does notbioaccumulate in the food chain.

ResultAquatic Toxicity

Based on the available data, likely to cause aharmfulness to aquatic organisms.

Biodegradation

Readily biodegradable.

PBT/ vPvB conclusion

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

6. Exposure
Consumer
The consumer can come into contact with the substance in use of the cosmetic products, but
the concentration of EMASOL S-30V in use is not concerned that it has a harmful effect. Whenit’s used as the recommended use, consumer should always read product information before
use and follow the label/ use instructions.
WorkerThe exposure can occur either in EMASOL S-30V manufacturing facilities or in the various
industrial facilities when EMASOL S-30V is used. Those workers in industrial operations
during maintenance, sampling, testing, or other procedures could be exposed with EMASOL
S-30V. Only qualified and trained workers handle the undiluted substance. The manufacturingfacilities 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.
EMASOL S-30V may be assigned to following GHS classification.

Classification and Labeling Information
Aquatic Acute 3Hazard Statements:
H402: Harmful to aquatic life
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
EMASOL S-30V could cause harmfulness to aquatic organisms. However, EMASOL S-30V is
unlikely to persist in the environment because of showing the readily biodegradation. EMASOL
S-30V is not applicable to PBT/vPvB. When handling the substance, workers should follow
the standard safety measures and refer to the Safety Data Sheet. Consumers will usually notcome into contact with the substance bulk and the substance is used diluted products,
therefore, it is considered that EMASOL S-30V gives rise no hazardous effects to humanhealth.
