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, hydrotreated light naphthenic:
ORAL (LD50): Acute: >5000 mg/kg [Rat].
DERMAL (LD50): Acute: >2000 mg/kg [Rabbit].
Distillates, petroleum, hydrotreated heavy naphthenic:
ORAL (LD50): Acute: >5000 mg/kg [Rat].
DERMAL (LD50): Acute: >2000 mg/kg [Rabbit].
Distillates, petroleum, hydrotreated light naphthenic:
INHALATION (LC50) Acute: 9.6 mg/L (Female Rat).
INHALATION (LC50) Acute: 10.5 mg/L (Male Rat).
ORAL (LD50) Acute: > 5,000 mg/kg (Rat screen level).
DERMAL (LD50) Acute: > 2,000 mg/kg (Rabbit screen level).
DRAIZE EYE Acute: Non-irritating (Rabbit).
DRAIZE DERMAL Acute: Mild skin irritant (Rabbit).
BUEHLER DERMAL Acute: Non-sensitizing (Guinea Pig).
28-Day DERMAL Sub-Chronic: Mild to moderate skin irritant (Rabbit & Rat).

A life-time dermal application of severely hydrotreated light naphthenic oils produced skin masses on
mice which correlated with the skin irritation response levels of the test animals. Additional studies
attribute these masses to a weak promotional activity. These studies indicate that light naphthenic oils
are not mutagenic, tumor initiators nor complete chemical carcinogens. These materials have not been
determined to be carcinogenic by IARC, NTP or OSHA.

Distillates, petroleum, hydrotreated heavy naphthenic:
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.


SECTION 12: ECOLOGICAL INFORMATION
Ecotoxicity 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. 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.
