    摘要： The invention relates to polyether-modified siloxanes which are both superspreading and readily biodegradable. In particular, the invention is directed to a composition including polyether-modified siloxanes of formula (I) MaDbD′c  Formula (I) with M=R13SiO1/2, D=R12SiO2/2, D′=R1R2SiO2/2, where a is 2, b is between 0 and 0.1, c is between 1.0 and 1.15, 0 and 1.05, R1 are independently hydrocarbyl having 1 to 8 carbon atoms, preferably methyl, ethyl, propyl or phenyl radicals, especially preferably methyl radicals, R2 are independently a polyether radical of the formula (II) —R3O[CH2CH2O]m[CH2CH(CH3)O]nR5  Formula (II) where m=3.4 to 11.0, n=2.5 to 8.0, wherein m/n=1.9 to 2.8, and R3 are independently divalent hydrocarbyl radicals having 2 to 8 carbon atoms, and R5 is hydrogen, wherein the polyether-modified siloxanes of formula (I) having a biodegradability of greater than 60%.
