11. TOXICOLOGICAL DATA
-------------------------------------------------------------------------- 
                         ---ACUTE TOXICOLOGY---
ORAL TOXICITY (RATS):  Practically non-toxic (LD50:  greater than 2000
     mg/kg).  ---Based on testing of similar products and/or the
     components.
DERMAL TOXICITY (RABBITS):  Practically non-toxic (LD50:  greater than
     2000 mg/kg).  ---Based on testing of similar products and/or the
     components.
INHALATION TOXICITY (RATS):  Practically non-toxic (LC50:  greater than 5
     mg/l).  ---Based on testing of similar products and/or the
     components.
EYE IRRITATION (RABBITS):  Practically non-irritating.  (Draize score:
     greater than 6 but 15 or less).  ---Based on testing of similar
     products and/or the components.
SKIN IRRITATION (RABBITS):  Practically non-irritating.  (Primary
     Irritation Index:  greater than 0.5 but less than 3).  ---Based on
     testing of similar products and/or the components.
OTHER ACUTE TOXICITY DATA: Although an acute inhalation study was not
     performed with this product, a variety of mineral oils, such as
     those in this product, have been tested.  These samples had
     virtually no effect other than a nonspecific inflammatory response
     in the lung to the aerosolized mineral oil.  The presence of
     additives in other tested formulations (in approximately the same
     amounts as in the present formulation) did not alter the observed
     effects.

                  ---SUBCHRONIC TOXICOLOGY (SUMMARY)---
No significant adverse effects were found in studies using repeated
     dermal applications of similar formulations to the skin of
     laboratory animals for 13 weeks at doses significantly higher than
     those expected during normal industrial exposure.  The animals were
     evaluated extensively for effects of exposure (hematology, serum
     chemistry, urinalysis, organ weights, microscopic examination of
     tissues etc.).

                 ---REPRODUCTIVE TOXICOLOGY (SUMMARY)---
No teratogenic effects would be expected from dermal exposure, based on
     laboratory developmental toxicity studies of major components in
     this formulation and/or materials of similar composition.

                   ---CHRONIC TOXICOLOGY (SUMMARY)---
Repeated and/or prolonged exposure may cause irritation to the skin, eyes
     or respiratory tract.  Overexposure to oil mist may result in oil
     droplet deposition and/or granuloma formation.  The base oils in
     this product are severely solvent refined and/or severely
     hydrotreated.  Chronic mouse skin painting studies of severely
     treated oils showed no evidence of carcinogenic effects.  These
     results are confirmed on a continuing basis using various screening
     methods such as the Modified Ames Test, IP-346, and/or other
     analytical methods.

                      ---SENSITIZATION (SUMMARY)---
Not expected to be sensitizing based on tests of this product,
     components, or similar products.
