Thermal-Lube’s growing line of XL-9000 series
of EcoSynthetic®, BioSynthetic®,
and BioNatural® lubricants
are products fully formulated to exacting specifications with carefully selected
components that are each categorized as “environmentally compatible”, and
conducive to definite applications.

“…….The term ‘biobased
’ as defined by Farm
Security and Rural Investment Act
means a product determined by the U.S. Secretary of Agriculture to be a
commercial or industrial product (other than food or feed), that is composed in
whole or in significant part, of biological products or renewable domestic
agricultural materials (including plant, animal, and marine materials) or
forestry materials. In short, biobased industrial products are produced from
renewable plant and animal sources, and are generally presumed to be more
environmentally benign than their petroleum based counterparts. They are usually
biodegradable and can be returned to the earth at the end of their useful life
or recycled and used again……”

The ecological impact analysis of the entire life cycle of each individual
component has been addressed and applied to the overall effect that each
formulated lubricant from this series will have on the environment.

The overall toxicological potential of the XL-9000 series
of lubricants is evaluated by addressing the intrinsic
 of the material
itself and understanding the magnitude of exposure
to the ecosystem.
 Only when
these two parameters are evaluated together with the final
degradation analysis, can the total ecological impact of the lubricant be

For example: A toxic lubricant may not pose a threat to the environment if the exposure is
minimized or eliminated. On the other hand, a lubricant that is relatively
non-toxic may be an environmental concern if large amounts are exposed to a

Toxicity is related to exposure (or dose). This is generally determined by the amount of a
material in air or water to kill 50% of an organism population within a
pre-designated time period [LC50 (Lethal
Concentration)]. With direct oral and/or dermal doses to a particular species,
this value is referred to as the LD50 (Lethal
Dose to kill 50% of the species). LC50 values
greater than 100ppm, LD50oral
values greater than 2000mg/Kg body weight, and LD50 dermal
values greater than 5000mg/Kg body weight are generally considered non-toxic.

Ecotoxicity is correlated to the bioaccumulation potential (concentration of chemicals from
water or food into living organisms). This is determined by the degree of
uptake, distribution, metabolism, and elimination of a substance within a living

For example: A material that is taken up and widely distributed, but metabolised and
eliminated, will not bioaccumulate. Similarly, a material that is not taken up
cannot bioaccumulate. However, bioaccumulation will occur when some highly
lipid-soluble materials will be taken up and stored in fats (lipids).

Final biodegradation of a lubricant is the last criterion to be assessed. Degradation may override many
harmful characteristics such as toxicity and bioaccumulation.

For example: A lubricant that degrades may not be an ecological threat even though the material
is toxic and/or bioaccumulates. Final degradation may occur by hydrolysis,
photolysis, and biodegradation.

Determining biodegradation tendencies of a lubricant is difficult because of its
hydrophobic nature. The test method being developed and used as of this writing
is the CEC L-33-T-82 test. This measures the oxygen consumption or carbon
dioxide production in a closed aqueous (inoculum) system for 28 days.

Materials analyzed by this test method can be categorized as readily,
inherently, or relatively biodegradable as compared to mineral oils. Readily
biodegradable lubricants will degrade a minimum of 60% in 28 days. Inherently
and relatively biodegradable lubricants will degrade over 15% in 28 days. What
this actually means is that inherently and readily biodegradable lubricant
products will degrade, but over a longer period of time.

In many industrial applications where lubricants are subjected to harsh or
outdoor conditions, and long lubricant life is expected, inherently
biodegradable lubricants would be the desirable choice. Thermal-Lube’s XL-9000
of synthetic lubricant products are all non-toxic, non-bioaccumulator, and
inherently biodegradable.  In applications where lubricant leakage,
environmental contamination, and toxicity pose ecological problems, readily
biodegradable lubricants would be the desirable choice. Thermal-Lube’s XL-9000
BioSynthetic® and
of lubricant products are all non-toxic, non-bioaccumulator, and readily
