GLOBAL PRODUCT STRATEGY SAFETY SUMMARYEMULGEN 306P
This document is a high-level summary provides usage of chemical substances and safety
information to the general public. It is not intended to replace the Safety Data Sheet, which isavailable from suppliers and should be referred to for full details of recommended safety
procedures for each type of use. It is not intended to replace or supersede manufacturer’sinstructions and warnings for their consumer products containing this substance.

1. Substance Identity
Brand Name: EMULGEN 306P
Chemical Name: Polyoxyethylene (6) stearyl ether
CAS Number: 9005-00-9

2. Uses and Applications
EMULGEN 306P is a nonionic surfactant. EMULGEN 306P is characterised by low skinirritation and is used as an emulsifier in quasi-drugs and cosmetics.
In industrial applications, EMULGEN 306P is used as an emulsifier for fabric processing
agents due to its low damage to textiles.

3. Physical/Chemical Properties
EMULGEN 306P has no identified physicochemical hazards.

4. Human Health Safety Assessment
The Short-term and repeated exposure of EMULGEN 306P 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 306P could
cause a strong toxicity to aquatic organisms. It also could cause harmfulness to aquaticorganisms with long lasting effects. However, EMULGEN 306P is unlikely to persist in theenvironment because of showing the readily biodegradation. EMULGEN 306P does notbioaccumulate in the food chain.

Effect Assessment

ResultAquatic Toxicity

Based on the available data, likely to cause a strong
toxicity 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.

6. Exposure
Consumer
The consumer can come into contact with the substance in use of the cosmetic products, but
the concentration of EMULGEN 306P in use is not concerned that it has a harmful effect.
When it’s used as the recommended use, consumer should always read product information
before use and follow the label/ use instructions.
Worker
The exposure can occur either in EMULGEN 306P manufacturing facilities or in the various
industrial facilities when EMULGEN 306P is used. Those workers in industrial operations
during maintenance, sampling, testing, or other procedures could be exposed with EMULGEN
306P. 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 306P 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, and

you 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
in order to remove the substance. No specific measures are needed, because it is notexpected 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 306P may be assigned to following GHS classification.

Classification and Labeling Information
Aquatic Acute 1
Aquatic Chronic 3

Hazard Statements:
H400: Very toxic to aquatic life
H412: Harmful to aquatic life with long lasting effects

Signal WordWarning
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
EMULGEN 306P could cause a strong toxicity to aquatic organisms. However, EMULGEN
306P is unlikely to persist in the environment because of showing the readily biodegradation.
EMULGEN 306P 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 not come into contact with the substance bulk and the substance is used diluted
