3 - Hazards Identification
SPECIAL INDICATION OF HAZARDS TO HUMANS AND THE ENVIRONMENT
Harmful in contact with skin and if swallowed. Irritating to eyes,
respiratory system and skin.
4 - First Aid Measures
AFTER INHALATION
If inhaled, remove to fresh air. If not breathing give

AFTER SKIN CONTACT
In case of contact, immediately wash skin with soap and copious
amounts of water.
AFTER EYE CONTACT
In case of contact with eyes, flush with copious amounts of
water for at least 15 minutes. Assure adequate flushing by
separating the eyelids with fingers. Call a physician.
AFTER INGESTION

SENSITIZATION
Sensitization: Prolonged or repeated exposure may cause allergic
reactions in certain sensitive individuals.
SIGNS AND SYMPTOMS OF EXPOSURE
The sodium salt of dodecyl sulfate has been reported to cause
pulmonary sensitization resulting in hyperactive airway
dysfunction and pulmonary allergy accompanied by fatigue,
malaise, and aching. Significant symptoms of exposure can
persist for more than two years and can be activated by a
variety of nonspecific environmental stimuli such as automobile
exhaust, perfumes, and passive smoking. To the best of our
knowledge, the chemical, physical, and toxicological properties
have not been thoroughly investigated.
ROUTE OF EXPOSURE
Skin Contact: Causes skin irritation.
Skin Absorption: Harmful if absorbed through skin.
Eye Contact: Causes eye irritation.
Inhalation: May be harmful if inhaled. Material is irritating to
mucous membranes and upper respiratory tract.
Ingestion: Harmful if swallowed.
TARGET ORGAN INFORMATION
Lungs.
CONDITIONS AGGRAVATED BY EXPOSURE
Causes sneezing. Do not inhale.
