____________________________________________________________________________________

EYE PROTECTION: This product does not cause significant eye irritation or eye toxicity requiring 
special protection. Use good industrial practice to avoid eye contact.

SKIN PROTECTION: Although this product does not present a significant skin concern, minimize skin
contamination by following good industrial practice. Wearing of protective gloves is recommended.
Wash hands and contaminated skin thoroughly after handling.

RESPIRATORY PROTECTION: Avoid breathing vapor or mist. Use NIOSH/MSHA approved respiratory
protection equipment when airborne exposure is excessive. Consult respirator manufacturer to determine
appropriate type equipment for given application. Observe respirator use limitations specified by
NIOSH/MSHA or the manufacturer. Respiratory protection programs must comply with 29 CFR § 1910.134.

VENTILATION: Provide natural or mechanical ventilation to minimize exposure. If practical, use local
mechanical exhaust ventilation at sources of air contamination such as open process equipment.

AIRBORNE EXPOSURE LIMITS:

11. TOXICOLOGICAL INFORMATION
___________________________________________________________________________________

Data from Solutia single-dose (acute) animal studies on this material indicate the following:

Oral - Practically Nontoxic (Rat LD50: >17,800 mg/kg)
Dermal - Practically Nontoxic (Rabbit LD50: >15,800 mg/kg)
Eye Irritation - Practically Nonirritating (Rabbit, 24 hr., 3.7/110)
Skin Irritation - Nonirritating (Rabbit, 24 hr., 0.3/8.0)

Additional toxicity studies have not been performed on this product. However, applicable toxicity information
is available on the related formulation of the parent free acid and its salt:

Slight effects on bone mineralization were noted following subcutaneous injection of this material
(as the neutral sodium salt) into rats for 7 days. Reduced body weights and changes in liver, spleen, and
kidney weights or weight ratios were observed following dietary administration of this material (as the
solid active acid) to rats for 24 months. An unusual tumor type (osteosarcoma - axilla) was noted in
one high dose male rat; the relevance of this finding to toxicity in humans is unclear.

No birth defects were noted in rats or mice given this material (as the neutral sodium salt) orally during
pregnancy. No effects were seen on the ability of male and female rats to reproduce when given
this material (as the solid active acid) in their diet for 3 successive generations.

This material produced no genetic changes in standard assays using bacteria. One positive response
was noted in an in vitro test with mammalian cells, but the assay was negative for the neutralized active acid.

Environmental Toxicity Information::

Environmental toxicity studies have not been conducted with this product. Tests have been performed,
however, with the parent acid of this product. Data obtained from environmental toxicity studies on the
parent acid are discussed below.

The following data have been classified using the criteria adopted by the European Economic Community
(EEC) for aquatic organism toxicity. A legend summarizing the classification scheme appears below.

96-hr 14-day 14-day
Algae EC50* 20 mg/L 20 mg/L * 20 mg/L 20 mg/L

* Algae growth inhibition is due to the ability of this material to complex nutrients, not toxicity per se.

Invertebrates
Daphnia magna 48-hr EC50, 297 mg/L: Practically NonToxic 48-hr EC50, 297 mg/L: Practically NonToxic
Midge Larvae 48-hr LC50, 11,400 mg/L: Practically NonToxic
Grass Shrimp 96-hr LC50, 4,575 mg/L: Practically NonToxic
Oyster Shell Deposition 96-hr EC50, 201 mg/L: Practically NonToxic

Fish
Bluegill Sunfish 96-hr LC50, >330 mg/L: Practically NonToxic
Rainbow Trout 96-hr LC50, >330 mg/L: Practically NonToxic
Channel Catfish 96-hr LC50, 1,212 mg/L: Practically NonToxic
Sheepshead Minnow 96-hr LC50, 8,132 mg/L: Practically NonToxic
Rainbow Trout 14-day LC50, 150 mg/L

Birds
Mallard Duck Oral LD50, >2,510 mg/kg: Practically NonToxic
Bobwhite Quail Oral LD50, >2,510 mg/kg: Practically NonToxic

NOTE: All values are "mg active acid/liter".

Rainbow trout eggs were exposed to the parent acid of this material at concentrations of
0, 4.9, 12.5, 23.0, 47.6 and 89.4 mg/L. No treatment-related effects were observed on hatchability
of eggs or survival of the fry. Reductions in weight and length of fry were observed after 45 and 60 days
of exposure to the two high-dose concentrations. The maximum acceptable toxicant concentration
was estimated to be between 23.0 and 47.6 mg/L.

Daphnia magna were exposed to the parent acid at concentrations ranging from 3.37 to 400 mg/L
for 28 days. Reductions in adult Daphnia survival and reproduction were observed at concentrations
above 25 mg/L. The maximum acceptable toxicant concentration was greater than 25 mg/L 
and less than 50 mg/L.

Carp were continuously exposed to the radiolabeled active acid of the parent acid at nominal
concentrations of 0.14 and 1.2 mg/L for 49 days, after which remaining fish were transferred to water
without the parent acid for 14 days. Tissue residue analysis determined that the radiolabeled active acid
of the parent acid did not bioconcentrate in the edible tissues. Radio-labeled residues did accumulate
in the non-edible tissues (viscera including ingesta and fecal material). Elimination of the residues from
the non-edible tissues of the carp was rapid and extensive after transfer to this material in free water.

Legend for Aquatic Organism Toxicity (Journal of the European Communities, Annex VII A, Section 5.2.1)

When evaluated in a microbial biodegradation assay, DEQUEST® 2000 Deflocculant and Sequestrant
active acid biodegradation to CO2 was classified as slow to resistant.
