k Sltt,c;
For the 1990's and beyond . perhaps no issue
is of greater importance to formulators and
users of chemical products than those relating
to human health and the environment . With
respect to these issues, solvents - along with
many other classes of materials - have been
the object of an unprecedented level of research .
We believe that DOWANOL* glycol ethers
will continue to emerge from this scrutiny as solvents of choice for the future. Fundamentally, their
toxicological and environmental properties are
sound, particularly those of our extensive P-Series
(propylene-based) line.
Further, and perhaps equally important,
DOWANOL glycol ethers offer performance features that make them an exceptional match to the
changing needs of formulators as they confront
health and environmental issues .
We've prepared this literature to help you
understand DOWANOL products from a health
and environmental perspective. The advantages
actually begin with the enthusiasm and the services we put behind every DOWANOL product .
Dow Services:
A Vital First Step
At the core of our service philosophy is our
dedication to helping customers achieve maximum performance from a minimum amount of
precisely the right solvent . We understand that
the efficient use of solvents is science, not art.
And by making continuous advances in solvent
science, we can help make that "minimum
solvent" target a vital link in your health and
environmental program .
ASOS Program - Our Applied Science of
Solvency (ASOS') program is one tool were
continuously developing to benefit all customers
and potential users of DOWA.NOL glycol ethers .
First, the ASOS program is designed to extract
maximum performance from our existing products
by advancing solvent science in general . We've
also defined ASOS as our program for the active
development of new oxygenated solvents to meet
customer needs .
2
For example, the ASOS program includes
solubility mapping techniques to assist end product
formulators and resin producers in making ideal
matches between solvents and resins . In a similar
fashion, the ASOS program includes ongoing work
to optimize matches between resins and coupling
solvents in water-reducible systems.
To assist in reformulation, our ASOS program
includes another dimension called CHEMCOMP'
services. CHEMCOMP services use computerized
mathematical models to aid in matching evaporation
rates and composition changes when changing from
one solvent blend to another.
New Oxygenated Solvents - As health and
environmental issues drive changes in basic formulation technology, appropriate new solvents
must be developed. We're actively engaged in the
search for new solvents, and our ASOS program
is helping us develop them to more precisely
match customer needs than ever before .
Reformulation Assistance - No matter what
your application is, there are many reformulation
situations in which our experience and technology can be of considerable assistance . If you
need to switch from a low-solids to a high-solids
solvent-borne system, call on us for the products
and technology that make efficient, active solvency the backbone of environmentally compliant formulations . We can also help you move
into water-borne and water-reducible systems .
Or, you may be considering a switch from
E-Series (ethylene-based) to P-Series (propylenebased) glycol ethers . With our broad and growing
line of P-Series DOWANOL glycol ethers, we're
the resource you can rely on for the right P-Series
product to match your specific formulation needs .

A Brief Review of Proper ties
and Applications
are much more than just efficient
an d therein lies a fundamental
reason for their growing accept ance . They offer a
remarkable combination of additional propert ies
Glycol ethers
organic solvents,
that often opens up completely new formulation
possibilities, or reduces the need for other
additives or solvents .
Coatings - Glycol ethers are helping coatings
formulators address health and environmental
issues in two significant ways .
Fast, glycol ethers provide active solvency,
rather than just diluent capability . This added
efficiency helps lower viscosity in high-solids
solvent-borne coatings designed to reduce total
VOC emissions .
And as regulatory issues drive the increasing
popularity of water-reducible and water-borne technology, glycol ethers are excellent solvent choices.
Glycol ethers are water compatible and are able to
compatibilize aqueous/organic multiphase systems .
So they're ideal coupling solvents for waterreducible coatings, as well as high-performance
coalescing agents for water-borne coatings .
Cleaners - As formulators of cleaning products
seek solvents with good toxicologic profiles,
glycol ethers are being specified more often,
particularly P-Series products.
With their dual aqueouslorganic properties,
glycol ethers can also help reduce or eliminate the
need for additional ingredients such as co-solvents,
surfactants, or hydrotropes. Glycol ethers effectively
reduce formulation surface tension . Their coupling
ability helps keep soils suspended. and can also help
to compatibilize other formulation ingredients .
Moreover, glycol ethers can help cleaning
formulators meet VOC regulations by reducin g
the total amount of solvent needed in a formulation .
Glycol ethers provide efficient, active solvency for
greases and oils, superior to that of many hydrocarbon solvents.
Other Applications - Glycol ethers are used
as solvents and coalescents for inks, agricultural
products, cosmetics, latex adhesives, and leather
dyes . As additives for jet fuel, they help prevent
ice buildup in fuel lines and inhibit bacteria
growth in fuel tanks .
The Clean Air Act
Amendments of 1990 and
DOWANOL Glycol Ether s
The sort of multifunctional performance
described above is likely to become more
valuable as the Clean Air Act Amendments
of 1990 progressively impact on formulation
technology . Higher-technology systems are
likely to become increasingly common, spurring the need for higher-performance, lesshazardous solvent systems .
Title I and VOCs - Almost all organic solvents
in use today are classified as VOCs (Volatile
Organic Compounds), and Title I of the 1990
Amendments calls for progressive reductions in
emissions of these materials . Thus, the expected
trends in formulation technology are likely to
favor more efficient, versatile solvents .
DOWANOL glycol ethers can address many
VOC-reduction needs through their efficiency in
high-solids, solvent-borne systems, their coupling
performance in water-reducible systems, and their
coalescing ability in water-borne systems.
Title III and HAPs - Title III of the 1990
Amendments lists a long series of materials or
classes of materials that are considered HAPs
(Hazardous Air Pollutants) . Under Title Ill, the
Maximum Achievable Control Technology
(MACT) standards that are being phased in during
the mid- 1990's will place increasing pressure on
formulators to reduce emissions of HAPs, or to
seek alternatives to them .
Since P-Series glycol ethers do not appear on
the HAPs list, it is likely that they will see increasing
use, both as alternatives in existing formulations as
well as the solvents of first choice in new systems .
The growing line of P-Series DOWANOL glycol
ethers offers an extensive range of evaporation rates
and other properties as options for formulators intent
on HAPs reduction.
At Dow, we're also working on new oxygenated solvents to further expand your ability to deal
with VOC- and HAP-related issues . These include
diethers of propylene glycol as well as butyleneoxide based glycol ethers and their acetates .
The following pages provide a more specific
look at the health and environmental properties of
DOWANOL glycol ethers . We invite your review of
this information, and we'll be glad to assist you in
any way we can if you require additional assistance .

The body of toxicological information on
DOWANOL glycol ethers and their acetates
is constantly growing . In addition to the data
in this brochure, we constantly update our
customer information regarding the toxicity,
storage, handling, and use of the glycol ethers
and acetates we sell . To obtain updated Material
Safety Data Sheets or additional information on
toxicology and handling, call 1-800 -447-4369 .
The Properties of Each
DOWANOL Product A re Unique
Although DOVeANOL glycol ethers all have
some fundamental similarities in chemical structure, there are significant differences among
them . Not only are DOWANOL products divided
broadly into ethylene-based (E-Series) and
propylene-based (P-Series) families, but no two
products in either family has the same toxicologic properties .
Broadly, toxicity studies have established that
there are very significant differences between
4
E-Series and P-Series glycol ethers . For example .
the comparative metabolism and disposition in rats
differs markedly for ethylene glycol methyl ether
(EM)' and the predominant isomer of propylene
glycol methyl ether (PM) . As shown in Figure 1 ,
the major metabolite of ethylene glycol methyl ether
was found to he methoxyacetic acid, while that of
propylene glycol methyl ether was found to be propylene glycol, which a multitude of studies indicate
is a substance with minimal toxicity . These differences in routes of metabolism and types of metabolites appear to be the basis for the remarkably
different toxicological properties of the two major
types of glycol ether products .
A careful review of the data in Table I
will underscore the importance of treating each
DOWANOL glycol ether as unique . While toxicologic studies such as the preceding example
have shown unfavorable results for some individual E-Series glycol ethers, no study has yet shown
an unfavorable pattern of toxicity for the entire
E-Series family.

Air Quality
Under current legislation, glycol ethers are considered as 100%c VOCs in calculations for all
types of formulations .
In solvent-borne systems containing no water,
VOC calculations can be made directly, with results
expressed as pounds solvent per gallon, or grams
solvent per liter . Conversions between the two
systems of measurement are provided here:

additional information, or have any questions
regarding these data, phone 1-800 -447-4369 .
Disposal
1 pound/gallon =119.87 grams/lite r
To convert from pounds per gallon to grams
per liter , multiply pounds by 119.87.
To convert from grams per liter to pounds per
gallon , divide grams by 119.87.
For systems containing water, the water must be
subtracted from the system before VOC content
is calculated . A formula frequently used for this
purpose by the U .S . Environmental Protection
Agency is :
( organic solvent

Following is a sample calculation using the above
formula for a model system containing 20%
DOWANOL PnB glycol ether by volume . 3013'%
water by volume, and 50% other ingredients by
volume . The density of DOWANOL PnB glycol
ether is 7 .31 pounds per gallon .
DO NOT DUMP DOWANOL GLYCOL
ETHERS INTO ANY SEWERS, ON THE
GROUND , OR INTO ANY BODY OF WATER .
For unused or uncontaminated mate ri al , the preferred management options are to send it to a
licensed recycler, reclaimer, or incinerator. The
same management options are recommended for
used or contaminated material, although additional evaluation is required . (See for example,
40CFR Part 261, "Identification and Listing of
Hazardous Waste .") Any disposal practice must
be in compliance with federal, state, provincial .
and local laws and regulations . Check with
appropriate agencies for your location .
