Product > Ethoxylates & PEG > NPE

In industry, alkylphenol ethoxylates (APEO) are widely used as non-ionic surfactants, nonylphenol ethoxylate (NPEO) and octylphenol ethoxylate being the main representatives of this group. Alkylphenol ethoxylates are widely used as :

. Washingand cleaning agents
. Emulsifiers in emulsion polymerizations
. Dispersion and wetting agents
. Adjuvants in drilling processes
. Adjuvants in dyeing mills
. Textile adjuvants used in bleaching, spinning, finishing, degreasing, and defoaming
. Pesticide formulations
 PEG-1000, 1500, 2000, 4000, 6000, 8000
. Softener
