摘要
This invention provides for, inter alia, a method for increasing the rainfastness of an agrochemical composition without increasing its spreading properties, which comprises adding to said agrochemical composition an effective amount of one or more silicone surfactants of the formula; ;wherein;n is 1 to 3,;R is an alkyl radical with 1 to 6 carbon atoms,;R′ is a radical of the structure; ; wherein;m is 2 to 6,;R″ is independantly methyl, ethyl or phenyl,;Z is hydrogen, an alkyl radical with 1 to 4 carbon atoms, or an acyl radical with 2 to 6 carbon atoms,;y is 6 to 30,;z is 0 to 10,;with the proviso that the ratio y/z is 1 or greater, and that the total number of alkylene oxide groups n*(y+z) in the siloxane polymer (I) is at least 12.
