5. Environmental Safety Assessment
The test results with fish, aquatic invertebrates and algae suggest that MYDOL 10 couldcause toxicity for aquatic organism. However, MYDOL 10 is unlikely to persist in theenvironment because of showing the readily biodegradation. MYDOL 10 is unlikely to cause
bioaccumulation by the food chain, because MYDOL 10 is not PBT/ vPvB.
Effect Assessment

ResultBased on the available data, likely to cause toxicity foraquatic organism 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 andvery bioaccumulating*PBT=Persistent, Bioaccumulative and ToxicvPvB=Very Persistent and Very Bioaccumulative
Aquatic Toxicity

6. ExposureConsumer
The consumer can come into contact with the substance in use of the detergent, and others,
but the concentration of MYDOL 10 in use is below the level which would give rise harmful
effects of concern. When it’s used as the recommended use, consumer should always readproduct information before use and follow the label/ use instructions.
WorkerThe exposure can occur either in MYDOL 10 manufacturing facilities or in the various
industrial facilities when MYDOL 10 is used. Those workers in industrial operations during
maintenance, sampling, testing, or other procedures could be exposed with MYDOL 10.
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 betrained 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 plantsfrom industrial 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
substance is biologically degraded in the surface water even if it remained slightly in thewaste water. Hence, the chronic exposure to aquatic organisms of the substance is unlikely
to occur. Furthermore, the substance does not accumulate by the food chain, and there is noconcern to human health by the exposure of the substance through environmental pathway.

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. When it causes your skin irritation, seek medical advice/attention.
If the substance gets into your eyes, rinse your eyes thoroughly for several minutes. If you
wear contact lenses, and you can take it off easily, take it off and continue to rinse your eyes.
Contact to a doctor immediately.
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 notexpected to be released into the air.

8. Regulatory Information/Classification and Labeling
Under GHS classification chemical substances are classified in hazards for physicalproperties, 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 understandthe hazards of the chemicals in use through the transmission.
Labeling according to UN GHS
UN GHS is the basis for country specific GHS labeling.
MYDOL 10 may be assigned to following GHS classification.

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

9. Conclusion
Though MYDOL 10 is suggested to cause toxicity to aquatic organisms, there is no concern
to the environmental organisms due to the rapid biodegradation of MYDOL 10. In thePBT/vPvB assessments for MYDOL 10, the substance is not PBT/vPvB. Contact with theundiluted MYDOL 10 may cause serious damage to the eyes. When handling the substance,
workers should follow the standard safety measures and refer to the Safety Data Sheet.
Consumers will usually not come into contact with the substance bulk and the substance isused diluted products, therefore, it is considered that MYDOL 10 gives rise no hazardous
effects to human health.
