Fatty Alcohol Ethoxylate 

DEV product line results from the reaction of fatty alcohols with ethylene oxide and propylene oxide. Because of the fatty chain and the amounts of ethylene oxide and propylene oxide in each molecule, we obtain products with different degrees of water solubility and foaming power. This allows you to choose an appropriate product for each application. The DEV L and DEV I lines are represented by the following general formula:
                                                                                                 R-O-(C2H4O)x (C3H6O)y H

The products of the DEV L and DEV I lines are non ionic compounds, whose lipophilic portion of the molecule comes from fatty alcohol and propylene oxide, and the hydrophilic part from the addition of ethylene oxide. This structure gives the line an extremely low foaming power, excellent wetting properties and good detergency.
Paints and Coatings
In addition to their significant surface tension reduction power in aqueous solutions, the products from the DEV L line have good wetting and dispersion properties, which enable their use in the manufacture of pigmented pastes, acrylic and vinylic latex paints. Being low foam nonionics, the need for anti-foams used in such preparations is reduced.

DEV Fatty Alcohol Alkoxylates present foaming properties significantly lower than traditional fatty alcohol ethoxylates, therefore are recommended for water based detergent formulations that require controlled foam. Though excellent wetting agents and low foam surfactants, DEV products have comparably lower cloud points and are less soluble in water.

Depending on the formulation, the addition of hydrotopes or solvents, such as isopropanol, secbutanol, monoethyleneglycol, butylglycol or butyldiglycol may be required for formulation stability and cloud point control. DEV INTERNATIONAL has a highly specialized team of experts that can assist in the correct DEV choice and use level for your application.

DEV L products are recommended as wetting agents in rinse-aids, automatic dishwashing detergents and low foam I&I degreasers. These products are also useful in acidic truck cleaners, aluminum brighteners and commercial tunnel car washes.

DEV I has the lowest foaming capacity in the line, also functioning as an anti-foam agent in the presence of other surfactants. It is recommended for wetting and detergency in bottle washing and dairy & brewery tank cleaners where non-foaming surfactants stable in acidic formulations are required.

DEV L products are recommended as nonylphenol ethoxylate alternatives in auxiliary textile preparation formulas. DEV I can be used in textile purging since its hydrophobic part is branched, which increases compatibility of waxes from natural textile fibers.
