Product Applications
  • Agriculture: Can be used as an emulsifier and wetting agent in preparation of agricultural toxicant formulations.
  • Paper Processing:  A superior rewetting agent for increasing the absorbency of paper towels, blotting paper and other absorbent papers. Other uses include de-inking, de-resination, felt washing, leveling colors, pitch control and re-pulping.
  • Wetting Agent: A superior wetting agent and rewetting agent for general applications: dust settling, corrosion inhibitors, metal cleaners, and pickling, “wetter water” for fire fighting.
  • Detergents & Cleaning Specialties:  Versatile in formulating a variety of household and industrial cleaning products such as all purpose liquid detergents, controlled foaming heavy duty laundry detergents, abrasive cleaners, silver polishes, copper cleaners, floor cleaners, porcelain cleaners, window cleaners, and waterless hand cleaners. Industrial applications include acid cleaners, alkaline soak tank cleaners, soak tank cleaners, and electrolytic cleaners.
  • Textiles: Successfully used for scouring textiles in all stages of manufacture. The wetting ability, emulsifying properties and dispersing action makes it valuable in other textile applications such as bleaching, desizing, dyeing, printing, soaping, carbonizing and as an emulsifier for polyethylene.
  • Petroleum: Used in water floods of secondary oil recovering operations.
