4. Human Health Safety Assessment
The Short-term and repeated exposure of EMULGEN 350 does not cause any toxic effects.
Effect Assessment

ResultBased on the available data, no acute toxicity
after oral/dermal exposure in 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 EMULGEN 350 could
cause a toxicity to aquatic organisms. However, EMULGEN 350 is unlikely to persist in theenvironment because of showing the readily biodegradation. EMULGEN 350 does notbioaccumulate in the food chain.

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

6. Exposure
Consumer
EMULGEN 350 is limited to industrial use. In addition, since there is little elution of EMULGEN
350 from industrial products, there is little exposure to consumers.
WorkerThe exposure can occur either in EMULGEN 350 manufacturing facilities or in the various
industrial facilities when EMULGEN 350 is used. Those workers in industrial operations during
maintenance, sampling, testing, or other procedures could be exposed with EMULGEN 350.
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
EMULGEN 350 is discharged to waste water treatment facilities from industrial sites such as
manufacturing, preparation, handling, storage and use of the substance. However, thesubstance is readily biodegradable, so that it is removed efficiently in waste water treatment
facilities. The substance is biologically degraded in the surface water and is rapidly removed
even if it is remained slightly in the waste water. Hence, the chronic exposure to aquaticorganisms of the substance is unlikely to occur. Furthermore, the substance dose notaccumulate in the food chain, so that there is no concern of human exposure throughenvironmental 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), wash with a large amount of water and soap. When itcauses your skin irritation, consult doctor (medical diagnosis/therapy). If the substance gets
into your eyes, rinse your eyes thoroughly for several minutes. If you wear contact lens, andyou can take it off easily, take it off and continue to rinse your eyes. If eye irritation persists,
get medical help.

Waste water containing the substance must be passed the waste water treatment facilities 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.
EMULGEN 350 may be assigned to following GHS classification.

Classification and Labeling Information
Aquatic Acute 2

Hazard Statements:
H401: Toxic to aquatic life

Signal Wordnone
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. ConclusionEMULGEN 350 could cause a toxicity to aquatic organisms. However, EMULGEN 350 isunlikely to persist in the environment because of showing the readily biodegradation.
EMULGEN 350 is not applicable to PBT/vPvB. When handling the substance, workers should
follow the standard safety measures and refer to the Safety Data Sheet. EMULGEN 350 islimited to industrial use. In addition, since there is little elution of EMULGEN 350 from industrial
products, there is little exposure to consumers.
