Recommended Uses & Known 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.

Packaging & Availability

Storage & Handling

Storage, Stability and Handling Information
  • T-Det “N” non-ionics are stable non- corrosive products in an anhydrous state.
  • They can be stored in plain steel tanks with piping, valves, and pumps of the same metal.
  • Aqueous solutions of T-Det “N” surfactants must be stored in stainless steel or plastic lined tanks.
  • The nonyl phenol-ethylene oxide adducts are slightly hydroscopic.
  • Where it is necessary to guard against atmospheric moisture pick-up, an inert gas blanket may be used.
  • It should not be mixed with concentrated oxidizing or reducing agents since the mixture of these compounds with organic compounds could form a potentially explosive mixture.
