UN Class or Division /  Subsidiary Risks

DIALLYL PHTHALATE
131-17-9

The substance will polymerize if not inhibited, due to heating or in the presence of a catalyst • On combustion, forms toxic carbon oxides • Reacts with strong oxidants, bases and acids

DIBUTYL PHTHALATE
84-74-2

As a result of flow, agitation, etc, electrostatic charges can be generated

The substance decomposes on burning producing toxic and irritating fumes (phthalic anhydride)

DICYCLOHEXYL PHTHALATE
84-61-7

Reacts with acids, bases

DIETHYL PHTHALATE
84-66-2

The substance decomposes on heating or on burning producing toxic fumes and gases (phthalic anhydride) • Attacks some plastics

DIISODECYL PHTHALATE
26761-40-0

Attacks some forms of plastics

DIISOOCTYL PHTHALATE
27554-26-3

Reacts with strong oxidants

DI-sec-OCTYL PHTALATE
117-81-7

Reacts with strong oxidants, acids, alkalis, and nitrates

For UN Class: 1.5 = very insensitive substances which have a mass explosion hazard; 2.1 = flammable gas; 2.3 = toxic gas; 3 = flammable liquid; 4.1 = flammable solid; 4.2 = substance liable to spontaneous combustion; 4.3 = substance which in contact with water emits flammable gases; 5.1 = oxidizing substance; 6.1 = toxic; 7 = radioactive; 8 = corrosive substance
