SECTION 10 – STABILITY AND REACTIVITY

Chemical Stability: 

Stable 

 

 

 

 

Hazardous 

Polymerization:   

Not expected to occur.

Conditions to Avoid:

 

  Keep away from extreme heat, sparks, open flame and strong oxidizing 

 

 

conditions.

Materials Incompatibility:

  Strong oxidizers

Hazardous 

Decomposition Products:

  No additional hazardous decomposition products were identified other 

 

than the combustion products identified in section 5 of this MSD

SECTION 11 – TOXICOLOGICAL INFORMATION

For other health-related information, refer to the Emergency Overview on Page 1, and the Hazards identification in 

Section 3 of this MSDS.

Toxicity Data:   

 

 

Distillates, petroleum, solvent-refined heavy paraffinic:

ORAL (LD50):   

 

 

Acute: >5000 mg/kg [Rat].

DERMAL (LD50): 

 

 

Acute: >2000 mg/kg [Rabbit].

Distillates, petroleum, solvent-refined heavy paraffinic:

Mineral oil mists derived from highly refined oils are reported to have low acute and sub-acute toxicities in animals.

Effects from single and short-term repeated exposures to high concentrations of mineral oil mists well above 

applicable workplace exposure levels include lung inflammatory reaction, lipoid granuloma formation and lipoid 

pneumonia.  In acute and sub-acute studies involving exposures to lower concentrations of mineral oil mists at or near 

current work place exposure levels produced no significant toxicological effects.  In long term studies (up to two 

years) no carcinogenic effects have been reported in any animal species tested. Analyses conducted by method 

IP346 indicate that the polycyclic aromatic concentration of this mineral oil is below 3.0 weight percent.

SECTION 12 – ECOLOGICAL INFORMATION

Eco-toxicity: 

Analysis for ecological effects has not been conducted on this product.  However, if spilled, 

 

this product and any contaminated soil or water may be harmful to human, animal, and 

 

aquatic life.Also, the coating action associated with petroleum and petroleum products can be 

 

harmful or fatal to aquatic life and waterfowl.

Environmental Fate:  

An environmental fate analysis has not been conducted on this specific product.  However, 

 

plants and animals may experience harmful or fatal effects when coated with petroleum-based 

 

products.  Petroleum-based (mineral) lube oils will normally float on water.  In stagnant or 

 

slow-flowing waterways, an oil layer can cover a large surface area.  As a result, this oil layer 

 

might limit or eliminate natural atmospheric oxygen transport into the water.  With time, if not 

 

removed, oxygen depletion in the waterway might be enough to cause a fish kill or create an 

 

anaerobic environment.

SECTION 13 – DISPOSAL CONSIDERATIONS

Hazard characteristic and regulatory waste stream classification can charge product use.  Accordingly, it is the responsibility 

of the user to determine the proper storage, transportation, treatment and/or disposal methodologies for spent materials and 

residues at the time of disposition.

Conditions of use may cause this material to become a hazardous waste, as defined by Federal or State regulations.  It is the responsibility 

of the user to determine if the material is a hazardous waste at the time of disposal.  Transportation, treatment, storage and disposal of 

waste material must be conducted in accordance with RCRA regulations (see 40 CFR 260 through 40 CFR 271).  State and/or local 

regulations may be more restrictive.  Contact the RCRA/Superfund Hotline at (800) 424-9346 or your regional US EPA  office for 

guidance concerning case specific disposal issues.

THE INFORMATION HEREIN IS GIVEN IN GOOD FAITH, BUT NO WARRANTY, EXPRESS OR IMPLIED, IS MADE.
