DIBUTYL PHTHALATE
CASRN: 84-74-2
Major Uses :
PLASTICIZER IN NITROCELLULOSE LACQUERS,
ELASTOMERS, EXPLOSIVES, NAIL POLISH & SOLID ROCKET PROPELLANTS; SOLVENT FOR
PERFUME OILS; PERFUME FIXATIVE; IN TEXTILE LUBRICATING AGENT; IN SAFETY GLASS;
IN PRINTING INKS; RESIN SOLVENT; PAPER COATINGS; IN ADHESIVES
Hazards Summary :
The major hazards encountered in the use and
handling of dibutyl phthalate stem from its toxicologic
properties. Toxic by all routes (ie, inhalation, ingestion, dermal contact),
exposure to this colorless-to-yellow, oily liquid may occur from its use as a
plasticizer or solvent in lacquers, elastomers, chlorinated rubbers, polyvinyl
acetate, explosives, nail polish, perfumes, resins, printing inks, paper
coatings, and adhesives. Effects from exposure may
include contact burns to the skin and eyes, dermatitis, nausea, and dizziness.
Both the OSHA PEL and the ACGIH TLV have been set at 5 mg/cu m. Odor thresholds
have been found as low as 0.26 mg/cu m. Ventilation should be used to maintain
acceptable levels. In activities where over-exposure may occur, wear a
self-contained breathing apparatus and protective clothing. If contact should
occur, immediately flush affected skin and eyes with running water for at least
15 minutes. While dibutyl phthalate does not ignite
easily, it may burn with the production of irritating or poisonous gases. Fires
involving dibutyl phthalate may be extinguished with
dry chemical, CO2, or Halon. Standard foam or water fog, if used, should be
applied with caution, as each may cause violent frothing. Dibutyl
phthalate may be shipped via air, rail, road, and water. If small amounts
of dibutyl phthalate should spill, take up with sand or
other noncombustible absorbent and place into containers for later disposal. For
large spills, first dike far ahead of the area with soil, sand bags, foamed
polyurethane, or foamed concrete, then absorb bulk material with fly ash or
cement powder. For large spills in bodies of water, first use natural barriers
or oil spill control booms to limit spill motion, then apply detergent, soap, or
alcohols to thicken material. Apply "universal" gelling agent and
remove trapped material with suction hoses. If dissolved, apply activated
charcoal, and use mechanical dredges or lifts to remove immobilized masses.
Before implementing land disposal of waste dibutyl phthalate, consult
with environmental regulatory agencies for guidance. Also, dibutyl
phthalate is a good candidate for liquid injection, rotary kiln, and
fluidized bed forms of incineration.
FDA Requirements :
Dibutyl phthalate is
an indirect food additive for use only as a component of adhesives.
