In order to obtain anionic polyoxyethylene phosphate surfactants, either the terminal hydroxy group of a polyoxyethylated hydrophobic substance is reacted with a phosphorylating agent or a phosphate ester is oxalkylated. Most often aliphatic and aliphatic-aromatic alcohols are first treated with an alkylene oxide and afterward with one of the phosphorylating agents, such as P4OI0, POCl3, phosphoric acid, or polyphosphoric acid [39-48]. 

Studies of the soil removal properties of polyoxyethylenated straight-chain primary alcohols on cotton and Dacron-cotton permapress fabric indicate that this detergency maximum with change in the number of oxyethylene units in the POE chain is also shown on these fabrics. In liquid no-phosphate formulations built only with diethanolamine to provide an alkaline pH, optimum removal of both sebum and clay soils from Dacron-cotton permapress at 49°C in 150 ppm hard water occurs with about 5, 9, and 10 oxyethylene units for POE C9-11, C12-15, and C16-18 alcohol mixtures, respectively. For removal of the same soils from cotton at the same temperature, the optimum POE chain lengths are about two oxyethylene units larger (Albin, 1973). 

The effect of changing the hydrophilic group from nonionic to anionic can be seen by comparing the soil removal properties of these same POE alcohols with two series of anionics made from the same hydrophobes, either by sulfating the alcohol mixture directly or after polyoxyethylenation with 3 or 6 mol of ethylene oxide. Using the same liquid no-phosphate formulation and the same laundering conditions at 49°C in 150 ppm hard water, the following results were obtained (Albin, 1973) ...

Polyfunctional aliphatic isocyanate (Sumitomo Bayer Urethan Co., Ltd. Sumidur N NCO, 16.5X) was used as a cross-linker. Phosphate ester comprising mainly phosphorated polyoxyethylenated long-chain alcohols (Toho Chemical Industry Co., Ltd RL-210 mean molecular weight, 63O) was used as a surface active agent. Solutions in toluene of these samples were reverse-roll coated onto the film and dried in an air circulating oven at 90 C for 5 minutes.
