  • Surface active agent based on polyoxyalkylenated (1-phenyl ethyl) phenols, the process for preparation thereof and the use thereof for producing emulsifiable concentrated solutions of active materials
    Patent number: 5082591
    Abstract: A surface active agent formed by a polyoxethylenated and polyoxypropylenated di and/or tri (1-phenyl ethyl) phenol with 16 to 35 statistically distributed recurrent oxyalkylenated units. The ratio between the number of recurrent oxyethylenated units and the number of recurrent oxypropylenated units ranges from 75/25 to 90/10. The surface active agent is prepared by means of the reaction of a di and/or tri (1-phenyl ethyl) phenol and a mixture of monoethylene glycol and monopropylene glycol with a monoethylene giycol/monopropyleneglycol molar ratio ranging from 75/25 to 90/10. The surface active agent can be used for producing concentrated emulsifiable solutions of active materials, in particular phytosanitary materials.
