 Technical Data

 Berol 266 is described as a narrow range ethoxylated alcohol, which means that the ethylene oxide distribution curve is  more narrow than a standard ethoxylated alcohol.
 Berol 266 is a low foam non-ionic surfactant, which gives less foam than broader range equivalents. 
 The proportion of unreacted alcohol is very low in Berol 266, which gives the product improved performance and
 reduced odour. This is of great importance in some cleaning operations, where free alcohol causes problems due to
 its strong smell, and irritation to eyes and throat.
 Berol 266 has two cloud points in water which makes it efficient both on hydrophobic and hydrophilic soil.
 Berol 266 has a very good cleaning effect on hard surfaces, and is intended for use in waterbased alkaline cleaners
 e.g. vehicle cleaning, engineering cleaning, all porpose cleaning etc.
 Berol 266 can also be used in detergents for textiles. 

 Handling

 Berol 266 should always be homogenized before use, unless the entire quantity is used.
