Odour Threshold:
No information was located.

Warning Properties:
Information not available for evaluation.

Composition/Purity:
Sodium isopropyl xanthate is available in technical grade only and is generally 90-95% pure. It is usually available as powder or pellets.

It also exists as a dihydrate. Sodium isopropyl xanthate may also be sold as a solution in water. It is shipped in steel drums.

Uses and Occurrences:
Sodium isopropyl xanthate is used mainly as a collector in the flotation of metal sulfide ores. Minor uses include curing and vulcanization of rubber; as an antioxidant for rubber; as a herbicide and defoliant, pesticide and fungicide; as a high-pressure lubricant additive; as a fortifying agent for certain oils; for analytical procedures; and in a froth flotation process for soils contaminated with mercury.(1)
Historically, sodium isopropyl xanthate was used as an intermediate in the manufacture of saccharin.(1,12)


SECTION 3. HAZARDS IDENTIFICATION

EMERGENCY OVERVIEW:
Pale yellow crystals or powder when pure. Also available in solution. Disagreeable odour of carbon disulfide (similar to decaying cabbage). The solid is hygroscopic. The solid is a REACTIVE FLAMMABLE MATERIAL. It reacts with moisture to form very toxic and extremely flammable carbon disulfide, especially at increased temperatures. Spontaneous combustion may occur due to the formation of carbon disulfide. Water solutions are relatively stable, unless they are heated, the pH is below 8 or greater than 13, or they have aged. Heating or burning may result in the formation of carbon disulfide, carbonyl sulfide, ethyl mercaptan, diethyl sulfide, ethyl disulfide, hydrogen sulfide, and sulfur oxides. The dry powder is a COMBUSTIBLE DUST and may form explosive dust-air mixtures. The solid and solutions may be harmful if absorbed through the skin and may be irritating to the skin and respiratory tract. EYE IRRITANT. Causes severe eye irritation.



POTENTIAL HEALTH EFFECTS

Effects of Short-Term (Acute) Exposure

Inhalation:
Sodium isopropyl xanthate dusts or mists from solution are probably irritating to the nose, throat and upper respiratory tract under normal conditions of use. There is no human or animal toxicity information available.
The solid or water solutions can give off very toxic and extremely flammable carbon disulfide vapour. The rate at which carbon disulfide is generated from the solid material increases with temperature and humidity (moisture). The rate of carbon disulfide generation from solution increases with temperature, low pH (acidic conditions) and/or pH greater than 13, as well as with time.(1,2,12)
Relatively low concentrations of carbon disulfide can harm the central nervous system (CNS). Early symptoms may include headache, dizziness, fatigue, excitement or depression. High concentrations can cause serious psychological disturbances (excitability, confusion, extreme, irritability, nightmares) and death. For further information, refer to the CHEMINFO review of carbon disulfide.

Skin Contact:
The dust can absorb moisture from the skin and may produce irritation. Solutions may also cause irritation, depending on the pH, the presence of certain contaminants like sodium hydroxide and sodium carbonate and/or the age of the solution. Slight irritation was observed following a 24-hour contact with the solid in one animal study.
Sodium isopropyl xanthate may be absorbed through the skin and may cause harmful effects by this route of exposure based on limited animal information for a closely related chemical (sodium ethyl xanthate) and a human case report involving exposure to an unspecified xanthate compound.
A 32-year old male reagent mixer became covered in xanthate powder and water solution (specific xanthate not specified) staining his skin green from the chest down. He was wearing disposable paper overalls over cotton overalls, polyvinyl chloride gloves and an acid-gas/particulate full-face negative pressure respirator. Twenty hours later, he experienced abdominal pain, loss of appetite, nausea, vomiting, headache and fatigue, and had mild itchiness at the wrists only. His symptoms resolved within 4 days. Based on spot measurements taken following the incident, concentrations of carbon disulfide in the air at the site were less than 10-60 ppm. A metabolite of carbon disulfide was detected in his urine at a low level. Many of the reported symptoms are consistent with carbon disulfide toxicity. However, the delayed onset of symptoms made the diagnosis of carbon disulfide toxicity slightly less certain. Skin contamination was probably the major exposure route in this situation, but inhalation exposure may also have occurred.(17)

Eye Contact:
Sodium isopropyl xanthate powder is a severe eye irritant based on animal information. Solutions may also be severely irritating, depending on the pH, the presence of certain contaminants like sodium hydroxide and sodium carbonate and/or the age of the solution. No human information was located.

Ingestion:
Sodium isopropyl xanthate may be slightly toxic if ingested, based on an animal toxicity value. There is no human information available. Sodium isopropyl xanthate will form carbon disulfide in the body, if ingested. Therefore, harmful effects may be similar to those observed following ingestion of carbon disulfide. These effects have included tremors, exhaustion, shortness of breath, reduced body temperature, dilation of the pupils, convulsions, coma and possibly even death. Ingestion is not a typical route of occupational exposure.

Effects of Long-Term (Chronic) Exposure

There is no human information available for sodium isopropyl xanthate.

Consult the CHEMINFO review for a discussion of the potential long-term effects of occupational exposure to carbon disulfide.

Skin:
Sodium isopropyl xanthate may cause dry, red, itchy skin (dermatitis), based on unconfirmed reports.(1)

Skin Sensitization:
There is insufficient information available to conclude that sodium isopropyl xanthate is a skin sensitizer.
No human case reports were located. Slight positive responses were reported at 48 hours in 4/20 guinea pigs in one animal study.

Carcinogenicity:

There is no human or animal information available for sodium isopropyl xanthate.

The International Agency for Research on Cancer (IARC) has not evaluated the carcinogenicity of this chemical.

The American Conference of Governmental Industrial Hygienists (ACGIH) has no listing for this chemical.

The US National Toxicology Program (NTP) has not listed this chemical in its report on carcinogens.

Teratogenicity and Embryotoxicity:
There is no human or animal information available for sodium isopropyl xanthate.

Reproductive Toxicity:
There is no human or animal information available for sodium isopropyl xanthate.

Mutagenicity:
There is no human or in vivo animal information available. Negative results have been obtained in tests using cultured cells.

Toxicologically Synergistic Materials:
Ingestion of alcoholic beverages may increase the toxicity of xanthates.(1, unconfirmed) In a study with guinea pigs, it was found that the amount of carbon disulfide exhaled, increased as the amount of ethanol in which a xanthate (diethylxanthate disulfide) was dissolved, increased.(3)

Potential for Accumulation:
There is no specific information available. Sodium isopropyl xanthate probably does not accumulate in the body. Carbon disulfide was detected in the exhaled air after oral administration of single doses of 150 and 250 mg of sodium ethyl xanthate (a closely related chemical) to humans.(3)


SECTION 4. FIRST AID MEASURES

Inhalation:
If irritation is experienced, remove source of contamination or move victim to fresh air and obtain medical advice. If symptoms of carbon disulfide exposure develop (e.g. headache, dizziness, fatigue or excitement), take proper precautions to ensure your own safety before attempting rescue (e.g. wear appropriate protective equipment, use the "buddy" system). Remove source of contamination or move victim to fresh air. If breathing has stopped, trained personnel should begin artificial respiration (AR) or, if the heart has stopped, cardiopulmonary resuscitation (CPR) or automated external defibrillation (AED) immediately. Avoid mouth-to-mouth contact by using mouth guards or shields. Quickly transport victim to an emergency care facility.

Skin Contact:
Avoid direct contact. Wear chemical protective clothing, if necessary. Remove contaminated clothing, shoes and leather goods (e.g. watchbands, belts). Immediately flush with lukewarm, gently flowing water for 15-20 minutes. Immediately obtain medical attention. Double bag, seal, label and leave contaminated clothing, shoes and leather goods at the scene for safe disposal.

Eye Contact:
Avoid direct contact. Wear chemical protective gloves, if necessary. Immediately flush the contaminated eye(s) with lukewarm, gently flowing water for 15-20 minutes, while holding the eyelid(s) open. If a contact lens is present, DO NOT delay irrigation or attempt to remove the lens until flushing is done. Take care not to rinse contaminated water into the unaffected eye or onto the face. Immediately obtain medical attention.

Ingestion:
NEVER give anything by mouth if victim is rapidly losing consciousness, or is unconscious or convulsing. Have victim rinse mouth thoroughly with water. DO NOT INDUCE VOMITING. Have victim drink 240 to 300 mL (8 to 10 oz) of water. If vomiting occurs naturally, repeat administration of water. If breathing has stopped, trained personnel should begin artificial respiration or, if the heart has stopped, cardiopulmonary resuscitation (CPR) immediately. Avoid mouth-to-mouth contact by using mouth guards or shields. Quickly transport victim to an emergency care facility.

First Aid Comments:
Provide general supportive measures (comfort, warmth, rest).
Consult a doctor and/or the nearest Poison Control Centre for all exposures except minor instances of inhalation or skin contact.
All first aid procedures should be periodically reviewed by a doctor familiar with the material and its conditions of use in the workplace.



SECTION 5. FIRE FIGHTING MEASURES

Flash Point:
Solid xanthates release extremely flammable carbon disulfide (closed cup flash point: -30 deg C (-22 deg F)) on contact with moisture.(2,17) Freshly prepared solutions do not normally exhibit a flash point by standard methods until heated to a point well above room temperature when decomposition occurs.(2)

Lower Flammable (Explosive) Limit (LFL/LEL):
1% (carbon disulfide) (2,6); 1.3% (carbon disulfide) (5,6)

Upper Flammable (Explosive) Limit (UFL/UEL):
50% (carbon disulfide) (2,5,6)

Autoignition (Ignition) Temperature:
Approximately 250 deg C (482 deg F) (dry solid xanthates) (2); 90 deg C (190 deg F) (carbon disulfide) (5)

Sensitivity to Mechanical Impact:
No information is available.

Combustion and Thermal Decomposition Products:
Carbon disulfide, carbonyl sulfide, isopropanol, isopropanethiol, aldehydes, diisopropyl sulfide, diisopropyl disulfide, hydrogen sulfide and sodium sulfide form when sodium isopropyl xanthate is heated to decomposition.(1,8) In a fire, these chemicals can decompose further to carbon monoxide, carbon dioxide and sulfur oxides.(9)

Flammable Properties:

Specific Hazards Arising from the Chemical:
Exposure to the heat of a fire can cause decomposition of sodium isopropyl xanthate solid and solutions to extremely flammable and very toxic carbon disulfide. A combination of moisture and heat may result in spontaneous combustion, due to the formation of carbon disulfide. The heat generated by hydration and/or decomposition reactions may be sufficient to raise the temperature to the autoignition temperature of carbon disulfide (90 deg C). Closed containers may explode if exposed to excess heat for a sufficient period of time releasing large quantities of carbon disulfide.

Extinguishing Media:
Carbon dioxide, dry chemical powder or appropriate foam. Foam manufacturers should be consulted for recommendations regarding types of foams and application rates.

Extinguishing Media to be Avoided:
DO NOT use water or water-based extinguishers on solid xanthates since extremely flammable and very toxic carbon disulfide will be released. Water may be used to keep non-leaking, fire-exposed containers cool.

Fire Fighting Instructions:
If a fire occurs in the vicinity of containers of sodium isopropyl xanthate, evacuate area and fight fire from a safe distance or a protected location. Approach fire from upwind to avoid extremely flammable and very toxic carbon disulfide and other toxic and flammable compounds. Wear full protective suit if exposure is possible. See Protection of Firefighters.
Closed containers may rupture violently when exposed to the heat of the fire. If possible, isolate materials not yet involved in the fire. Move containers from the fire area if this can be done without risk. Protect personnel. Otherwise, use water in flooding quantities as a spray to keep fire-exposed containers, drums, or tanks cool and absorb heat to help prevent rupture. Cooling should begin as soon as possible (within the first several minutes) and should concentrate on any unwetted portions of the container. Apply water from the side and from a safe distance. Take care not to get water inside the containers, since a very hazardous situation may result. Cooling should continue until well after the fire is out.
Water spray may also be used to knock down irritating/toxic combustion products that may be produced in a fire. Fire control water is likely to be contaminated with carbon disulfide, hydrogen sulfide and sulfur dioxide. Dike fire control water for appropriate disposal.
Stay away from the ends of tanks, but be aware that flying material (shrapnel) from ruptured tanks may travel in any direction. Withdraw immediately in case of rising sound from venting safety device or any discolouration of tank.
For an advanced or a massive fire, it may be prudent to use unmanned hose holders or monitor nozzles and evacuate the area.
Containers should not be approached directly after they have been involved in a fire, until they have been completely cooled down. After the fire has been extinguished, explosive and toxic atmospheres may be present. Before entering such an area, especially confined areas, check the atmosphere with an appropriate monitoring device while wearing full protective suit.

Protection of Fire Fighters:
The decomposition and combustion products of sodium isopropyl xanthate are extremely hazardous. Firefighter's normal protective equipment (Bunker Gear) will not provide adequate protection. A full-body encapsulating chemical protective suit with positive pressure self-contained breathing apparatus (NIOSH approved or equivalent) may be necessary.

SECTION 10. STABILITY AND REACTIVITY

Stability:
Solid xanthates are relatively stable if kept dry and cool. Solutions are also relatively stable if they are kept cool and the pH is maintained within an acceptable range. Under certain conditions, sodium isopropyl xanthate decomposes to very toxic and extremely flammable carbon disulfide. The rate of carbon disulfide generation from the solid increases with temperature and humidity (moisture); and from solutions increases with temperature, pH below 8 (becoming rapid below pH 7; acidic conditions) or pH greater than 13, as well as with time (aging of the solution).(1,12,17,19) Maximum stability of solutions is attained at a pH of approximately 10.(12,19)

Hazardous Polymerization:
Does not occur.

Flammable Gases Released Upon Contact with Water:
Solid xanthates release extremely flammable carbon disulfide gas upon contact with moisture in air at normal temperatures. The rate of carbon disulfide generation increases with increasing temperature. There have been several case reports of fires resulting from contact of solid xanthates with moisture.(12,17,19) Xanthate water solutions are more stable than the solid. The rate of carbon disulfide generation from solutions increases with pH below 8 (accelerating below pH 7) or pH greater than 13, an increase in temperature and/or aging of the solution.(12,17,19)

Incompatibility - Materials to Avoid:

NOTE: Chemical reactions that could result in a hazardous situation (e.g. generation of flammable or toxic chemicals, fire or detonation) are listed here. Many of these reactions can be done safely if specific control measures (e.g. cooling of the reaction) are in place. Although not intended to be complete, an overview of important reactions involving common chemicals is provided to assist in the development of safe work practices.


ACIDS or ACIDIC SOLUTIONS - the hydrolysis of xanthate solutions, which produces carbon disulfide, is accelerated by acidic pH (less than 7).(17,19)
ALKALINE SOLUTIONS (pH greater than 13) - reacts to produce carbon disulfide, hydrogen sulfide, isopropanol, trithiocarbonate and sodium carbonate.(12,17)
STRONG OXIDIZING AGENTS (e.g. peroxides, nitrates and perchlorates) - risk of fire and explosion.
METAL SALTS (e.g. copper, iron, lead or zinc salts) - accelerate the decomposition to carbon disulfide.(17)

Hazardous Decomposition Products:
Decomposition products in water include carbon disulfide, isopropyl alcohol, trithiocarbonate and sodium carbonate.(2)

Conditions to Avoid:
Heat, age, moisture for solids. Heat, age, pH lower than 8 and higher than 13 for solutions.

Corrosivity to Metals:
Dry sodium isopropyl xanthate is not expected to be corrosive to metals. (Carbon steel is generally suitable for use with xanthates.(1,2)) The moist material or solutions decompose to form carbon disulfide, which attacks copper and copper alloys at normal temperatures and becomes very corrosive to iron and steel at temperatures above 250 deg C.(11)

Corrosivity to Non-Metals:
Dry sodium isopropyl xanthate is not expected to attack plastics and elastomers. The moist material or solutions decompose to form carbon disulfide, which can attack some plastics, elastomers, rubbers and coatings.(11) However, polyvinyl chloride or polyethylene may be used with xanthate solutions.(12)

Stability and Reactivity Comments:
Xanthate solids and solutions tend to release carbon disulfide, which may accumulate in containers. With solutions, carbon disulfide accumulates in the xanthate solution to the saturation point, then forms a separate layer. This layer forms at the bottom of the solution for sodium isopropyl xanthate and may accumulate in dead spaces, such as the bottom of storage tanks.(2,9)


SECTION 11. TOXICOLOGICAL INFORMATION

LD50 (oral, rat): approximately 800 mg/kg (5/8 died; administered as a 50% water solution) (20)
LD50 (oral, rat): greater than 250 mg/kg (no deaths) (1,17-unconfirmed)

LD50 (dermal, rat): greater than 1000 mg/kg (1/8 died; administered as a 50% water solution) (20)

Eye Irritation:

Sodium isopropyl xanthate powder is a severe eye irritant.

Instillation of 100-200 mg of sodium isopropyl xanthate powder into rabbit eyes produced severe irritation. Average scores for 24, 48 and 72 hours were: redness 1.9/3; chemosis 0.9/4; corneal opacity 2/4; iris injury 2/2. (20) OECD Guidelines specify administration of a maximum of 100 mg of the solid.

Skin Irritation:

Sodium isopropyl xanthate is a slight skin irritant.

Application of powdered sodium isopropyl xanthate to intact rabbit skin for 24 hours in a Draize test resulted in slight irritation (maximum average scores: erythema 0.7/4 at 24 hours; edema 0/4).(20)

Skin Sensitization:
There is insufficient information to conclude that sodium isopropyl xanthate is a skin sensitizer. Positive responses have been obtained in one study.
Sodium isopropyl xanthate was tested for skin sensitization potential in 10 guinea pigs/sex using the Magnusson and Kligman maximization test. Redness was scored on a 4 point scale (negative, trace, single positive, double positive). Single positive responses were recorded in 2/10 males and 2/10 females at 48 hours.(20) Observations were not recorded at 72 hours following exposure.

Mutagenicity:
The available information suggests that sodium isopropyl xanthate is not mutagenic.
Negative results were obtained in tests using bacteria and yeast, with and without metabolic activation, and in one test using cultured mammalian cells.(4)
