POLYACRYLIC ACID, SODIUM SALT	ICSC: 1429 (April 2008)
Sodium polyacrylate 2-Propenoic acid homopolymer, sodium salt Acrylic acid homopolymer, sodium salt Carboxy vinyl polymer, sodium salt

CAS #: 9003-04-7

	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Combustible. Finely dispersed particles form explosive mixtures in air.	NO open flames. Prevent deposition of dust.	Use powder, alcohol-resistant foam, water in large amounts, carbon dioxide.

PREVENT DISPERSION OF DUST!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Cough.	Use ventilation, local exhaust or breathing protection.	Fresh air, rest.
Skin		Protective gloves.	Remove contaminated clothes.
Eyes	Redness.	Wear safety spectacles.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Ingestion		Do not eat, drink, or smoke during work.	Rinse mouth.

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Wash away remainder with plenty of water.	According to UN GHS Criteria WARNING May cause damage to lungs through prolonged or repeated exposure if inhaled Transportation UN Classification
STORAGE
Separated from oxidants.
PACKAGING

POLYACRYLIC ACID, SODIUM SALT

ICSC: 1429

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance WHITE POWDER WITH CHARACTERISTIC ODOUR. Physical dangers Dust explosion possible if in powder or granular form, mixed with air. If dry, it can be charged electrostatically by swirling, pneumatic transport, pouring, etc. Chemical dangers Reacts violently with oxidants. This generates fire and explosion hazard.	Formula: (C₃H₃O₂)_n·Na Molecular mass: variable (polymer) See Notes. Density: 1.1 - 1.4 g/cm³ Solubility in water: good

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by ingestion. Effects of short-term exposure May cause mechanical irritation.	Inhalation risk A harmful concentration of airborne particles can be reached quickly when dispersed. Effects of long-term or repeated exposure Repeated or prolonged inhalation may cause effects on the lungs.

EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by ingestion.

Effects of short-term exposure
May cause mechanical irritation.

Inhalation risk
A harmful concentration of airborne particles can be reached quickly when dispersed.

Effects of long-term or repeated exposure
Repeated or prolonged inhalation may cause effects on the lungs.

OCCUPATIONAL EXPOSURE LIMITS

ENVIRONMENT

NOTES
The substance is combustible but no flash point is available in literature. Properties may vary with the molecular weight. Physical properties are for the acid form of the polymer. The recommendations on this Card also apply to (polyacrylic acid, CAS# 9003-01-4).
