Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Guidance on Safe Use
Administrative data
First-aid measures
Inhalation: If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention if symptoms appear.
Ingestion: If affected person is fully conscious, give one glass of water to drink. Never give anything by mouth to an unconscious person. Get medical attention if symptoms appear.
Skin contact: Wash with soap and water. Get medical attention if irritation develops.
Eye contact: In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Get medical attention immediately.
Fire-fighting measures
Suitable extinguishing media: In case of fire, use water spray (fog), foam or dry chemical or CO2.
Unsuitable extinguishing media: Do not use water jet.
Special hazards arising from the substance:
Hazards from the substance or mixture: None known
Hazardous combustion products: Decomposition products may include the following materials: carbon dioxide, carbon monoxide, phosphorus oxides.
Advice for firefighters:
Special protective equipment for fire-fighters: Fire-fighters should wear positive pressure self-contained breathing apparatus (SCBA) and full turnout gear.
Accidental release measures
Personal precautions, protective equipment and emergency procedures:
Immediately contact emergency personnel. Keep unnecessary personnel away. Use suitable protective equipment. Follow all fire-fighting procedures.
Environmental precautions and Methods for containment and cleaning up:
If emergency personnel are unavailable, contain spilled material. For small spills, add absorbent (soil may be used in the absence of other suitable materials) and use a non-sparking or explosion-proof means to transfer material to a sealable, appropriate container for disposal. For large spills, dike spilled materials or otherwise contain material to ensure runoff does not reach a waterway. Place spilled material in an appropriate container for disposal and dispose using an approved waste disposal plant. Avoid contact of spilled material with soil and prevent runoff entering surface waterways.
Handling and storage
(Generic advice and guidance is provided)
Precautions for safe handling: Avoid contact with eyes. Wash thoroughly after handling.
Conditions for safe storage, including any incompatabilities: Keep container tightly closed. Keep container in a cool, well-ventilated area.

Exposure controls / personal protection
Appropriate Engineering Controls:
Provide exhaust ventilation or other engineering controls to keep the airborne concentrations of vapors below their respective threshold limit value
Eye/Face Protection:
Safety goggles are considered minimum protection. Goggles with a face shield may be necessary depending on quantity of material and conditions of use.
Hand Protection:
Hand Protection: Wear chemical resistant gloves. Nitrile gloves of minimum thickness 0.4 mm have an expected breakthrough time of 480 minutes or less when in frequent contact with the product. Due to variable exposure conditions the user must consider that the practical use of a chemical-protective glove in practice may be much shorter than the permeation time above. Manufacturer’s directions for use, especially about the minimum thickness and the minimum breakthrough time, must be observed. This information does not replace suitability tests by the end user since glove protection varies depending on the conditions under which the product is used.
Body Protection:
Disposable outer garments when there is a risk of contact with the material.
Respiratory Protection:
No special requirement when used as recommended.
Environmental Exposure Controls:
Emissions from ventilation or work process equipment should be checked to ensure they comply with the requirements of environmental protection legislation. In some cases, fume scrubbers, filters or engineering modifications to the process equipment will be necessary to reduce emissions to acceptable levels.
Stability and reactivity
Reactivity: Non-reactive under normal conditions of storage and use.
Chemical stability: Stable under normal conditions of storage and use.
Possibility of hazardous reactions: DMOP is non-explosive, non-flammable and not an oxisising agent.
Conditions to avoid: High temperatures, sparks, and open flames.
Incompatible materials: Strong oxidizing and reducing agents.
Hazardous decomposition products: Decomposition products may include carbon dioxide, carbon monoxide and phosphorus oxides.
Disposal considerations
Waste handling and disposal: Waste must be disposed of in accordance with federal, state and local environmental control regulations.
