4. Human Health Safety Assessment
Consumer: The exposure to SANISOL B-50 is at safe levels.
Worker: The repeated exposure of SANISOL B-50 does not cause any toxic effects.
Effect Assessment

ResultHarmful if swallowed. The substance does
not cause damage to any organs following
single exposure
Undiluted substance causes strong skinirritation. 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

Acute Toxicity
oral/ dermal
Irritationskin/ eyeSensitization
Toxicity after repeated exposure
Mutagenicity
Carcinogenicity
Toxicity for reproduction

5. Environmental Safety Assessment
The test results with fish, aquatic invertebrates and algae suggest that SANISOL B-50 could
cause a strong toxicity to aquatic organisms. It also could cause harmfulness to aquaticorganisms with long lasting effects. However, SANISOL B-50 is unlikely to persist in theenvironment because of showing the readily biodegradation. SANISOL B-50 does notbioaccumulate in the food chain.

vPvB=Very Persistent and Very Bioaccumulative

6. Exposure
Consumer
The consumer can come into contact with the substance in use of detergent and homecleaning product, but the concentration of SANISOL B-50 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 read product information before use and follow the label/ use instructions.
Worker
The exposure can occur either in SANISOL B-50 manufacturing facilities or in the various
industrial facilities when SANISOL B-50 is used. Those workers in industrial operations during
maintenance, sampling, testing, or other procedures could be exposed with SANISOL B-50.
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 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. When the substance 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 and continue to rinse your eyes. When it causes your skin irritation or eyeirritation, 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.
SANISOL B-50 may be assigned to following GHS classification.

Classification and Labeling Information
Acute tox. - Oral 4
Skin irrit. 1

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
Though SANISOL B-50 is suggested to cause strong toxicity to aquatic organisms, there is noconcern to the environmental organisms due to the rapid biodegradation of SANISOL B-50. In
the PBT/vPvB assessments for SANISOL B-50, the substance is not applicable to PBT/vPvB.
When handling the substance, workers should follow the standard safety measures and referto the Safety Data Sheet. Consumers will usually not come into contact with the substancebulk and the substance is used diluted products, therefore, it is considered that SANISOL B50 gives rise no hazardous effects to human health.
