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.
