Toxicity for reproduction

No 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 EMAL 10 POWDER
could cause a toxicity to aquatic organisms. It also could cause harmfulness to aquaticorganisms with long lasting effects. However, EMAL 10 POWDER is unlikely to persist in theenvironment because of showing the readily biodegradation. EMAL 10 POWDER does notbioaccumulate in the food 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. Exposure
Consumer
The consumer can come into contact with the substance in use of laundry detergents, but theconcentration of EMAL 10 POWDER 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.
Worker
The exposure can occur either in EMAL 10 POWDER manufacturing facilities or in the various
industrial facilities when EMAL 10 POWDER is used. Those workers in industrial operations
during maintenance, sampling, testing, or other procedures could be exposed with EMAL 10POWDER. Only qualified and trained workers handle the undiluted substance. The
manufacturing facilities offer thorough training program for employees and appropriate work
processes, as well as safety equipment (goggles and gloves) in place to present anunnecessary 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 DataSheet.
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 largeamount 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.
EMAL 10 POWDER 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:

H228: Flammable solids
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

9. Conclusion
Though EMAL 10 POWDER is suggested to cause toxicity to aquatic organisms, there is noconcern to the environmental organisms due to the rapid biodegradation of EMAL 10POWDER. In the PBT/vPvB assessments for EMAL 10 POWDER, the substance is notapplicable to PBT/vPvB. When handling the substance, workers should follow the standard
safety measures and refer to the Safety Data Sheet. Consumers will usually not come intocontact with the substance bulk and the substance is used diluted products, therefore, it isconsidered that EMAL 10 POWDER gives rise no hazardous effects to human health.
