    Not a hazardous substance or mixture according to Regulation (EC) No. 1272/2008.
  2. Label elements
    Not a hazardous substance or mixture according to Regulation (EC) No. 1272/2008
  3. Other Hazards
    This substance/mixture contains no components considered to be either persistent, bioaccumulative and toxic (PBT), or very persistent and very bioaccumulative (vPvB) at levels of 0.1% or higher.
    Rapidly absorbed through skin.

Composition/information on ingredients

  1. Substances
    Synonyms : DMSO Dimethyl sulfoxide
    Formula : C2H6SO
    Molecular weight : 78.13 g/mol
    CAS-No. : 67-68-5
    EC-No. : 200-664-3
    No components need to be disclosed according to the applicable regulations.

First aid measures

  1. Inhalation
    If inhaled: Call a poison center or doctor if you feel unwell.
    Acute and delayed symptoms and effects: May cause respiratory irritation. Signs/symptoms may include cough, sneezing, nasal discharge, headache, hoarseness, and nose and throat pain. Exposure to high concentrations of Dimethyl sulfoxide could cause lowering of consciousness. Repeated exposure to DMSO vapors did not cause any irritation to the respiratory tract; however the exposure to high concentrations in the form of an aerosol induced an irritation of the upper airways after a repeated exposure.
  2. Eye Contact
    If in eyes: Rinse cautiously with water for at least 15 minutes. Remove contact lenses, if present and easy to do. Continue rinsing. Call a poison center or doctor if you feel unwell.
    Acute and delayed symptoms and effects: May cause eye irritation. Signs/symptoms may include redness, swelling, pain, tearing, and blurred or hazy vision. DMSO is slightly irritating for the eye. In studies performed following the OECD 405 or the EEC method B.5, a slight to moderate conjunctival irritation, which cleared in 3 days, was observed in the eyes of rabbits. In humans, the instillation of solutions containing 50 to 100% DMSO has caused transient sensation of burning which was reversible within 24 hours.
  3. Skin Contact
    If on skin (or hair): Take off immediately all contaminated clothing.
    Rinse skin with water or shower. Call a poison center or doctor if you feel unwell.
    Acute and delayed symptoms and effects: May cause skin irritation. Signs/symptoms may include localized redness, swelling, and itching. Dimethyl sulfoxide may accelerate skin absorption of other materials. A skin irritation assay performed in rabbit (OECD 404) revealed no more than a very slight or well-defined erythema, which disappeared in 3 days.
  4. Ingestion
    If swallowed: Call a poison center or doctor if you feel unwell. If vomiting occurs naturally, have victim lean forward to reduce the risk of aspiration. Do NOT induce vomiting unless directed to do so by medical personnel.
  5. General Advice
    In case of accident or if you feel unwell, seek medical advice immediately (show the label or SDS where possible).
  6. Note to Physicians
    Symptoms may not appear immediately.

Firefighting measures

  1. Extinguishing media
    Suitable extinguishing media
    Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide.
    Unsuitable extinguishing media
    Do NOT use water jet.
  2. Special hazards arising from the substance or mixture
    Carbon oxides, Sulphur oxides
  3. Advice for firefighters
    Wear self-contained breathing apparatus for firefighting if necessary.
  4. Further information<
    Use water spray to cool unopened containers.

Accidental release measures

  1. Personal precautions, protective equipment and emergency procedures
    Avoid breathing vapours, mist or gas. Remove all sources of ignition. Beware of vapours accumulating to form explosive concentrations. Vapours can accumulate in low areas.
    For personal protection see section 8.
  2. Environmental precautions
    Prevent further leakage or spillage if safe to do so. Do not let product enter drains
  3. Methods and materials for containment and cleaning up
    Contain spillage, and then collect with non-combustible absorbent material, (e.g. sand, earth, diatomaceous earth, vermiculite) and place in container for disposal according to local / national regulations (see section 13). Keep in suitable, closed containers for disposal.
  4. Reference to other sections
    For disposal see section 13.

Handling and storage

  1. Precautions for safe handling
    Avoid inhalation of vapour or mist.
    Keep away from sources of ignition – No smoking.Take measures to prevent the build up of electrostatic charge.
    For precautions see section 2.2.
  2. Conditions for safe storage, including any incompatibilities
    Keep container tightly closed in a dry and well-ventilated place. Store in cool place.
  3. Specific end use(s)
    Apart from the uses mentioned in section 1.2 no other specific uses are stipulated.

Exposure controls/personal protection

  1. Control parameters
    Components with workplace control parameters
    Contains no substances with occupational exposure limit values
  2. Exposure controls

    Appropriate engineering controls

    Handle in accordance with good industrial hygiene and safety practice. Wash hands before breaks and at the end of workday.
    Personal protective equipment
    Eye/face protection
    Safety glasses with side-shields conforming to EN166 Use equipment for eye
    protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU).
    Skin protection
    Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique (without touching glove’s outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices. Wash and dry hands.
    The selected protective gloves have to satisfy the specifications of Regulation (EU) 2016/425 and the standard EN 374 derived from it.Body Protection
    Impervious clothing, The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace.
    Respiratory protection
    Where risk assessment shows air-purifying respirators are appropriate use a full- face respirator with multi-purpose combination (US) or type ABEK (EN 14387) respirator cartridges as a backup to engineering controls. If the respirator is the sole means of protection, use a full-face supplied air respirator. Use respirators and components tested and approved under appropriate government standards such as NIOSH (US) or CEN (EU).
    Control of environmental exposure
    Prevent further leakage or spillage if safe to do so. Do not let product enter drains.
