Composition / Ingredient Information

First Aid Measures

Inhalation
If inhaled, remove to fresh air.  If not breathing, give artificial respiration.  If breathing is difficult, give oxygen.  Call a physician.

Skin Contact
Flush skin with water after contact.  Wash contaminated clothing before reuse.

Eye Contact
In case of contact immediately, flush eyes with plenty of water for at least 15 minutes.  Call a physician.

Ingestion
If swallowed, do not induce vomiting.  Allow victim to rinse his mouth and then to drink 2-4 cupfuls of water.  Never give anything by mouth to an unconscious person.  Call a physician.

Notes to Physicians
Activated charcoal mixture may be administered.  To prepare activated charcoal mixture, suspend 50 grams activated charcoal in 400-ml water and mix thoroughly.  Administer 5 ml/kg or 350 ml for an average adult.

Because of the danger of aspiration, emesis or gastric lavage should not be employed unless the risk is justified by the presence of additional toxic substances.  Activated charcoal may induce vomiting, but may be given after emesis or lavage to absorb toxic additives.  Steroid therapy in mild to moderate cases does not improve outcome.  Bacterial pneumonia often occurs after exposure, but prophylactic antibiotics are not indicated and should be reserved for documented bacterial pneumonia.

Exposure Controls

Engineering Controls
Use only with adequate ventilation.  Keep container tightly closed.

Personal Protective Equipment

Chemical Stability
Stable at normal temperatures and storage conditions.

Incompatibility
Incompatible with strong oxidizers/strong acids.

Decomposition
Thermally decomposes at 232C (450F).  Decomposition products include oxides of nitrogen.

Polymerization
Will not occur.

Toxicological Information

N, N-di-sec-butyl-p-phenylenediamine is corrosive to skin, is untested for eye irritancy, and is a skin sensitizer in animals.  Toxic effects described in animals from short exposures by inhalation,  ingestion, or skin contact include lung effects, kidney effects, liver effects, and nonspecific effects such as weight loss and irritation.  No animal test reports are available to define carcinogenic, mutagenic, embryotoxic, or reproductive hazards.

N, N, N-tri-sec-butyl-p-phenylenediamine is untested for skin or eye irritancy, and for animal sensitization.  The closely related N, N di-substituted compound is a skin corrosive, and a skin sensitizer in guinea pigs.  The effects in animals from acute, subchronic, or chronic exposure by inhalation, ingestion, or skin contact have not been determined.  The N, N di-substituted compound produces hemolysis (red blood cell breakage), methomoglobinemia, cyanosis and weight loss.

N-sec-butyl-p-phenylenediamine is untested for skin or eye irritancy, and for animal sensitization.  The closely related N, N di-substituted compound is a severe skin irritant, and a skin sensitizer in guinea pigs.  The effects in animals from acute, subchronic, or chronic exposure by inhalation, ingestion, or skin contact have not been determined.  The N, N di-substituted compound produces hemoglobinemia, methemoglobinemia, cyanosis and weight loss.
