The following Overview, *** IRRITANTS ***, is relevant for this HSDB record
chemical.
Life Support:
o This overview assumes that basic life support measures
have been instituted.
Clinical Effects:
0.2.1 SUMMARY OF EXPOSURE
0.2.1.1 ACUTE EXPOSURE
A) Whether a substance is labeled a "corrosive" or
"irritant" depends on several factors: the nature of
the substance, concentration, viscosity, pH, molarity,
oxidation-reduction potential, complexing affinity
toward bivalent ions etc. It is difficult to determine
if a substance is a corrosive or irritant at a
particular concentration.
B) Irritants are substances that cause inflammation and
swelling, but not cellular death and tissue damage; a
corrosive causes cellular damage and death.
C) Exposure via inhalation may result in headache,
rhinorrhea, cough, shortness of breath, chest pain,
bronchospasm and rarely, upper airway swelling or acute
lung injury.
D) Ingestion may cause irritation of the oral mucous
membranes and esophagus.
0.2.4 HEENT
0.2.4.1 ACUTE EXPOSURE
A) Irritants may cause swelling, redness and pain at any
site, especially at mucous membranes. The mouth, nose,
and eyes are susceptible to these effects.
0.2.6 RESPIRATORY
0.2.6.1 ACUTE EXPOSURE
A) Cough, tachypnea, and wheezing are common after
inhalation.
0.2.8 GASTROINTESTINAL
0.2.8.1 ACUTE EXPOSURE
A) Nausea, vomiting and diarrhea are possible if ingested.
0.2.14 DERMATOLOGIC
0.2.14.1 ACUTE EXPOSURE
A) Redness, swelling and pain may occur.
0.2.20 REPRODUCTIVE HAZARDS
A) Pregnant female rats were exposed to Nmethylpyrrolidone. Exposed offspring had normal motor
function, activity levels, and low-level learning
abilities. On higher-level learning tests, their
performance was impaired compared to unexposed
offspring.
0.2.21 CARCINOGENICITY
0.2.21.2 HUMAN OVERVIEW
A) Development of sinonasal neoplasms has been associated
with exposure to wood dust and other irritants.
Laboratory:
A) No specific laboratory tests are necessary with the
possible exception of testing the pH of the irritant
substance and the pH of the ocular cul de sac with wide
range pH paper.
Treatment Overview:
0.4.2 ORAL EXPOSURE
A) EMESIS - Not indicated due to the irritant nature of
these agents.
B) Charcoal - Not recommended; it may promote vomiting and
make endoscopic evaluation difficult.
C) DILUTION: Immediately dilute with 4 to 8 ounces (120 to
240 mL) of water or milk (not to exceed 4 ounces/120 mL
in a child).
D) NEUTRALIZATION - Neutralization is not indicated.
E) Although these agents are irritants, and therefore
should not produce tissue damage, it is almost
impossible to assure that a particular substance under a
particular set of circumstances would not cause damage.
Therefore, each patient should be examined with the idea
that mucous membrane damage might have occurred.
0.4.3 INHALATION EXPOSURE
A) INHALATION: Move patient to fresh air. Monitor for
respiratory distress. If cough or difficulty breathing
develops, evaluate for respiratory tract irritation,
bronchitis, or pneumonitis. Administer oxygen and assist
ventilation as required. Treat bronchospasm with inhaled
beta2 agonist and oral or parenteral corticosteroids.
0.4.4 EYE EXPOSURE
A) DECONTAMINATION: Irrigate exposed eyes with copious
amounts of room temperature water for at least 15
minutes. If irritation, pain, swelling, lacrimation, or
photophobia persist, the patient should be seen in a
health care facility.
B) If in a medical facility, sterile saline should be used
to irrigate the eyes until the cul de sac is returned to
neutrality. Some alkali exposures may require prolonged
irrigation.
Range of Toxicity:
A) The extent of damage will depend on a number of factors
including concentration, mechanism of action, pH, free
acidity and alkalinity, molarity and oxidation-reduction
potential. In most cases these factors are more important
than volume. Besides its irritant effect, a substance may
also have some type of systemic effect. Observe for any
potential systemic effects as is appropriate for each
compound.

Environmental Bioconcentration:
The mollusks, Cerastoderma lamarcki and Mytilaster lineatus absorbed and released a
more toxic oil, containing 1.22% naphthenic acids, from laboratory emulsions more
slowly than less toxic oil containing 0.24% naphthenic acids. The rates of filtration and
absorption decreased as the oil concn in water increased from 1.5 to 10.25 mg/l.
Mytilaster lineatus accumulated 0.0180 and 0.026 mg/l from the less and more toxic oil
suspensions, respectively, containing 2.5 and 1.5 mg oil/l, respectively. The less toxic oil
was eliminated completely within 57 days, whereas the residue of the more toxic oil in
the mollusks was 0.000035 mg/g after 47 days in clean water.

Preventive Measures:
SRP: The scientific literature for the use of contact lenses in industry is conflicting. The
benefit or detrimental effects of wearing contact lenses depend not only upon the
substance, but also on factors including the form of the substance, characteristics and
duration of the exposure, the uses of other eye protection equipment, and the hygiene of
the lenses. However, there may be individual substances whose irritating or corrosive
properties are such that the wearing of contact lenses would be harmful to the eye. In
those specific cases, contact lenses should not be worn. In any event, the usual eye
protection equipment should be worn even when contact lenses are in place.
**PEER REVIEWED**
SRP: Contaminated protective clothing should be segregated in such a manner so that
there is no direct personal contact by personnel who handle, dispose, or clean the
clothing. Quality assurance to ascertain the completeness of the cleaning procedures
should be implemented before the decontaminated protective clothing is returned for
reuse by the workers. Contaminated clothing should not be taken home at end of shift,
but should remain at employee's place of work for cleaning.

Formulations/Preparations:
Typical of the acid materials present in commercial naphthenic acids are
cyclopentylacetic acid and alkyl substituted cyclopentylacetic acids. The mixtures also
contain fused chains of cyclopentylacetic acids and small amounts of cyclohexylacetic
acids.
