oberflaechenaktiver substance on the basis of oxyethylierten and oxypropylierten phenyl 1 ethylphenolen, processes for their manufacture and their use to be concentrated solutions of active compounds.

摘要

Surface-active agent consisting of a polyoxyethylenated and polyoxypropylenated di- and/or tri(1-phenylethyl)phenol with 16 to 35 oxyalkylene units distributed randomly and a ratio of number of oxyethylene units/number of oxypropylene units of 75/25 to 90/10. …??It is prepared by reacting a di- and/or tri(1-phenylethyl)phenol with a mixture of monoethylene glycol and monopropylene glycol with a monoethylene glycol/monopropylene glycol molar ratio of 75/25 to 90/10. …??It is employed for preparing emulsifiable concentrated solutions of active, especially plant-protection, substances.
