Safety Profile:
DOWANOL DPnB glycol ether may cause mild to moderate eye irritation if direct contact occurs due to its solvent properties.
Its ability to disrupt lipid layers on the skin can lead to dryness or irritation with repeated or prolonged exposure.
This makes it important to use protective gloves and eye protection during handling.
The solvent can produce respiratory irritation when inhaled as vapor or mist, especially in poorly ventilated areas.
High concentrations may affect the upper respiratory tract by causing coughing, discomfort, or a burning sensation.
Adequate ventilation and proper respiratory protection reduce the likelihood of these effects.
DOWANOL DPnB glycol ether may be harmful if swallowed in significant amounts because it can affect the gastrointestinal system.
Ingestion may cause symptoms such as nausea, abdominal discomfort, or dizziness depending on dose and exposure duration.
Immediate medical attention is recommended if large ingestion occurs.
