Application
 
 
A. TEXTILE PROCESSING

The commercial use of polyoxyethylene derivatives was in the field of textile auxiliaries.

The wetting and detergent properties are important in many processing stages of cotton, such as prescouring, desizing, bleaching, kier boiling, and the application of resin finishes. The products are widely used for the alkaline or neutral scouring of wool as well as in acid carbonizing. They are useful in the processing of synthetic, especially in the formulation of finishes because of their antistatic, emulsifying and lubricating properties.
 
B. DETERGENTS
The major consumption of these non ionic is in domestic and commercial detergent. The domestic products are essentially all formulated products; in commercial   application, a considerable volume of non ionic is purchased for direct use but may also be compounded by the user.

Liquid dishwashers, originally RIMPRO NP-9 with about 15 % water, are to day usually formulated product whose main detergent is an anionic such as alkyl benzene sulfonate, polyoxyethelene alkyl phenol sulfate, or both. A form booster and stabilizer, usually lauric diethanolamine or dimethyldodecylamine oxide is usually included; many of the formulations will also include about 5 % of a water-soluble nonionic.

Heavy –duty products often contain about 15 % nonionic; the solid carrier is a mixture polyphosphates and silicates with a small amount of carboxymethyl cellulose as a soil-suspending agent.

Solvent-type cleaners containing 25 % or more of refined kerosene are usually formulated with about 10 % of the 9 mole adduct or with a combination of the 6 and 9 mole adducts. These products are popular for floors, woodworks, and general cleaning.

Other household products in which these nonionic used include window cleaners, waterless hand cleaners, metal dip cleaners, bubble bath and hard-water bar soaps.
 
C. METAL PROCESSING
The water soluble alkyl phenol derivatives are used to advantage in the acid pickling operation, where rust and scale are removed in the finishing of steel. They are included in rolling-oil formulations, in cutting and broaching oils of the soluble type, and in water-base hydraulic fluids used in operating heavy equipment such as presses.
 
 
D. AGRICULTURAL
A large amount of the non ionic is consumed in the manufacture of emulsifiable concentrates of insecticides and herbicides. Both the oil- soluble and water soluble type are used, and most often in conjunction with a sulfonate, sulfate or more recently, with the phosphate esters derived from a polyoxyethylene non ionic.
 
E. LATEX AND WAXES

The higher adducts containing 20 to 100 moles of ethylene oxide are used in the emulsion polymerization of vinyl acetate and acrylates. The water soluble members of short-chain length act as dispersants and stabilizers in synthetics rubber as well as other polymeric latices.Emulsion-type floor polishes are prepared from both natural and synthetics waxes with the higher adducts.

Other industries consuming substantial amounts of these adducts include petrolium:for drilling and crude-oil-emulsion breaking;paper:for pitch control in pulp, felt cleaning and rewetting of paper towels; cosmatics:emulsifier;leather:fat-liquoring;as dust control agent in the coal,mineral,and ceramic industries; and wetting and foaming adjuncts in fire fighting.

The chemical industry it self is a large consumer of these materials as an intermediate in the production of the sulfates, the phosphates, and the disinfectant iodophors
