6. ACCIDENTAL RELEASE MEASURES

Personal precautions

Use personal protection recommended in section 8.

Follow all recommended handling procedures.

Environmental precautions

Small quantities: present no environmental problem.

Large quantities: minimize spread.

Methods for cleaning up

into solution.

Do not store above 50 °C for prolonged time.

Exposure to a maximum of 50 °C for as long as two weeks will not

degrade this product.

Minimum shelf life: 2 years.

9. PHYSICAL AND CHEMICAL PROPERTIES

Physical state: slightly turbid liquid

Colour: pale yellow-green

Flash point: not applicable, non flammable

Insolubles: <= 0.0100 % w/w

Odour: amine

pH: 4.4 - 4.9 (as such)

________________________________________________________________________

10. STABILITY AND REACTIVITY

Conditions to avoid

Heating > 100 °C may generate pressure due to steam formation from

the water present.

Materials to avoid

This material will react with galvanised or unlined steel (except

stainless steel) to produce hydrogen, a highly flammable gas that

can cause explosions.

Should be mixed, stored and applied in stainless steel, aluminium,

fiberglass, plastic or plastic-lined steel containers.

Hazardous decomposition products

Phosphorus pentoxide, carbon dioxide.

11. TOXICOLOGICAL INFORMATION

Laboratory data

More concentrated formulation

Oral LD50 (rat): > 5000 mg/kg.

Dermal LD50 (rat): > 5000 mg/kg.

Overall mean EU eye irritation scores (OECD test, 24 h)(rabbit):

conjunctival redness: 1.11

conjunctival swelling: 0

corneal opacity: 0

iris lesions: 0

Lesions reversible by 7 days.

Slightly irritating to eyes but not sufficient for

classification.

Overall mean EU skin irritation scores (OECD test, 4 h)(rabbit):

redness: 0.11

swelling: 0

Lesions reversible by 72 days.

Guinea pig Buehler test: 0 % positive incidence.

Active ingredient

Tests on glyphosate showed that it did not cause any mutagenic,

carcinogenic, teratogenic or adverse reproductive effects.

It is not neurotoxic.

Human data

Formulation: no human data.

Experience suggests that the symptoms of ingestion of large

amounts of concentrated glyphosate/ethoxylated tallowamine

formulations are due to the surfactant rather than the glyphosate

itself.

New surfactant: this material is not expected to have severe

effects.
