For the 1990's and beyond . perhaps no issueis of greater importance to formulators andusers of chemical products than those relatingto human health and the environment . Withrespect to these issues, solvents - along withmany other classes of materials - have beenthe object of an unprecedented level of research .

We believe that DOWANOL* glycol etherswill continue to emerge from this scrutiny as sol-vents of choice for the future. Fundamentally, theirtoxicological and environmental properties aresound, particularly those of our extensive P-Series(propylene-based) line.

Further, and perhaps equally important,DOWANOL glycol ethers offer performance fea-tures that make them an exceptional match to thechanging needs of formulators as they confronthealth and environmental issues .

We've prepared this literature to help youunderstand DOWANOL products from a healthand environmental perspective. The advantagesactually begin with the enthusiasm and the ser-vices we put behind every DOWANOL product .

Dow Services:A Vital First Step

At the core of our service philosophy is ourdedication to helping customers achieve maxi-mum performance from a minimum amount ofprecisely the right solvent . We understand thatthe efficient use of solvents is science, not art.And by making continuous advances in solventscience, we can help make that "minimumsolvent" target a vital link in your health andenvironmental 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 extractmaximum 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 .

For example, the ASOS program includessolubility mapping techniques to assist end productformulators and resin producers in making idealmatches between solvents and resins . In a similarfashion, the ASOS program includes ongoing workto optimize matches between resins and couplingsolvents in water-reducible systems.

To assist in reformulation, our ASOS programincludes another dimension called CHEMCOMP'services. CHEMCOMP services use computerizedmathematical models to aid in matching evaporationrates and composition changes when changing fromone solvent blend to another.

New Oxygenated Solvents - As health andenvironmental issues drive changes in basic for-mulation technology, appropriate new solventsmust be developed. We're actively engaged in thesearch for new solvents, and our ASOS programis helping us develop them to more preciselymatch customer needs than ever before .

Reformulation Assistance - No matter whatyour application is, there are many reformulationsituations in which our experience and techno-logy can be of considerable assistance . If youneed to switch from a low-solids to a high-solidssolvent-borne system, call on us for the productsand technology that make efficient, active sol-vency the backbone of environmentally com-pliant formulations . We can also help you moveinto water-borne and water-reducible systems .

Or, you may be considering a switch fromE-Series (ethylene-based) to P-Series (propylene-based) glycol ethers . With our broad and growingline of P-Series DOWANOL glycol ethers, we'rethe resource you can rely on for the right P-Seriesproduct to match your specific formulation needs .

A Brief Review of Proper tiesand Applications

Glycol ethers are much more than just efficientorganic solvents, an d therein lies a fundamentalreason for their growing accept ance . They offer aremarkable combination of additional propert ies

that often opens up completely new formulationpossibilities, or reduces the need for otheradditives or solvents .

Coatings - Glycol ethers are helping coatingsformulators address health and environmentalissues in two significant ways .

Fast, glycol ethers provide active solvency,rather than just diluent capability. This addedefficiency helps lower viscosity in high-solidssolvent-borne coatings designed to reduce totalVOC emissions .

And as regulatory issues drive the increasingpopularity of water-reducible and water-borne tech-nology, glycol ethers are excellent solvent choices.Glycol ethers are water compatible and are able tocompatibilize aqueous/organic multiphase systems .So they're ideal coupling solvents for water-reducible coatings, as well as high-performancecoalescing agents for water-borne coatings .

Cleaners - As formulators of cleaning productsseek 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 theneed for additional ingredients such as co-solvents,surfactants, or hydrotropes. Glycol ethers effectivelyreduce formulation surface tension . Their couplingability helps keep soils suspended. and can also helpto compatibilize other formulation ingredients .

Moreover, glycol ethers can help cleaningformulators meet VOC regulations by reducin gthe total amount of solvent needed in a formulation .Glycol ethers provide efficient, active solvency forgreases and oils, superior to that of many hydrocar-bon solvents.

Other Applications - Glycol ethers are usedas solvents and coalescents for inks, agriculturalproducts, cosmetics, latex adhesives, and leatherdyes . As additives for jet fuel, they help preventice buildup in fuel lines and inhibit bacteriagrowth in fuel tanks .

The Clean Air ActAmendments of 1990 and

DOWANOL Glycol EthersThe sort of multifunctional performancedescribed above is likely to become morevaluable as the Clean Air Act Amendmentsof 1990 progressively impact on formulationtechnology . Higher-technology systems arelikely to become increasingly common, spur-ring the need for higher-performance, less-hazardous 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 inemissions of these materials . Thus, the expected

trends in formulation technology are likely tofavor 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 1990Amendments lists a long series of materials orclasses of materials that are considered HAPs(Hazardous Air Pollutants) . Under Title Ill, theMaximum Achievable Control Technology(MACT) standards that are being phased in duringthe mid- 1990's will place increasing pressure onformulators to reduce emissions of HAPs, or toseek alternatives to them .

Since P-Series glycol ethers do not appear onthe HAPs list, it is likely that they will see increasinguse, both as alternatives in existing formulations aswell as the solvents of first choice in new systems .The growing line of P-Series DOWANOL glycolethers offers an extensive range of evaporation ratesand other properties as options for formulators intenton HAPs reduction.

At Dow, we're also working on new oxygen-ated solvents to further expand your ability to dealwith VOC- and HAP-related issues . These includediethers of propylene glycol as well as butylene-oxide based glycol ethers and their acetates .

The following pages provide a more specificlook at the health and environmental properties ofDOWANOL glycol ethers . We invite your review ofthis information, and we'll be glad to assist you inany way we can if you require additional assistance .

The Properties of EachDOWANOL Product Are Unique

Although DOVeANOL glycol ethers all havesome fundamental similarities in chemical struc-ture, there are significant differences amongthem . Not only are DOWANOL products dividedbroadly into ethylene-based (E-Series) andpropylene-based (P-Series) families, but no twoproducts in either family has the same toxico-logic properties .

Broadly, toxicity studies have established thatthere are very significant differences between

E-Series and P-Series glycol ethers . For example .the comparative metabolism and disposition in ratsdiffers markedly for ethylene glycol methyl ether(EM)' and the predominant isomer of propyleneglycol methyl ether (PM) . As shown in Figure 1 ,the major metabolite of ethylene glycol methyl etherwas found to he methoxyacetic acid, while that ofpropylene glycol methyl ether was found to be pro-pylene glycol, which a multitude of studies indicateis a substance with minimal toxicity . These differ-ences in routes of metabolism and types of meta-bolites appear to be the basis for the remarkablydifferent toxicological properties of the two majortypes of glycol ether products .

A careful review of the data in Table Iwill underscore the importance of treating eachDOWANOL glycol ether as unique . While toxi-cologic studies such as the preceding examplehave shown unfavorable results for some indivi-dual E-Series glycol ethers, no study has yet shownan unfavorable pattern of toxicity for the entireE-Series family.

Air QualityUnder current legislation, glycol ethers are con-sidered as 100%c VOCs in calculations for alltypes of formulations .

In solvent-borne systems containing no water,VOC calculations can be made directly, with resultsexpressed as pounds solvent per gallon, or gramssolvent per liter. Conversions between the twosystems of measurement are provided here:

1 pound/gallon =119.87 grams/lite r

To convert from pounds per gallon to gramsper liter , multiply pounds by 119.87.

To convert from grams per liter to pounds pergallon , divide grams by 119.87.

For systems containing water, the water must besubtracted from the system before VOC contentis calculated . A formula frequently used for thispurpose by the U .S . Environmental ProtectionAgency is :

(volume fraction ( organic solventVOC organic solvent ) x density)

content ~ 1 -volume fraction water

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
