The present invention relates to certain alcohol alkoxylates of the amphiphilic type, to agrochemical agents comprising them, and to the use of the alcohol alkoxylates as activity-improving adjuvants in the agrochemical field and particularly in the field of plant protection. The alcohol alkoxylates are alkoxylated alcohols of the formula (I) R-O-[(C m1H2m1O)x-(C m2H2m2O)y-(C m3H2m3O)z]co-[(C2H40)p-(C3H60)g]co-Z (1) or the formula (II) R-O-(C n1H2n1O)o-[(C2H4O)p-(C3H6O)g]co-[(C m1H2m1O)x-(C m2H2m2O)y-(C M3H2m3O)z]co-Z (II), where R is an aliphatic linear or branched radical with 1 to 30 carbon atoms; n1 is 2 or 3; o is 0, 1, 2, or 3; m1, m2, m3 independently from each other are integers from 4 to 16; x is a value from 0 to 100; y is a value from 0 to 100; z is a value from 0 to 100; the sum of x, y, z is greater than zero; the sum of (m1 .cndot. x), (m2 .cndot. y), (m3 .cndot. z) and the number of carbon atoms in R in formula (I) or the sum of (m1 .cndot. x), (m2 .cndot. y), (m3 .cndot. z) and the number of carbon atoms in z in formula (II) is 15 to 60; p is a value of 0 to 100; q is a value from 0 to 100; the sum of p and q is greater than zero; z is hydrogen or an aliphatic linear or branched radical with 1 to 13 carbon atoms, wherein the radical R-O-[(C m1H2m2O)x-(C m2H2m3O)y-(C m3H2m.3O)z]co- in formula (I) or the radical -[(C m1H2m1O)x-(C m2H2m2O)y-(C m3H2m3O)z]co-Z in formula (II) comprises 2 to 12 total branches und 0.1 to 0.3 branches per carbon atom.

L'invention concerne des alcoxylates d'alcool de type amphiphile déterminés, des agents agrochimiques les contenant, ainsi que l'utilisation des alcoxylates d'alcool comme adjuvants dans le domaine agrochimique et notamment dans le domaine phytosanitaire. Ces alcoxylates d'alcool sont des alcools alcoxylés de formule (I) R-O-[(Cm1H2m1O)x-(Cm2H2m2O)y-(Cm3H2m3O)z]co-[(C2H4O)p-(C3H6O)q]co-Z (l) ou de formule (II) R-O-(Cn1H2n1O)o-[(C2H4O)p-(C3H6O)q]co-[(Cm1H2m1O)x-(Cm2H2m2O)y-(Cm3H2m3O)z]co-Z (II), R désignant un reste linéaire ou ramifié aliphatique ayant entre 1 et 30 atomes de carbone; n1 vaut 2 ou 3; o vaut 0, 1, 2 ou 3; m1,,2,,3 désignent indépendamment les uns des autres un nombre entier compris entre 4 et 16; x a une valeur comprise entre 0 et 100; y a une valeur comprise entre 0 et 100; z a une valeur comprise entre 0 et 100; la somme de x, y et z supérieure à zéro; la somme de (m1 x), (m2 y), (m3 z) et le nombre d'atomes de carbone dans R dans la formule (I) et respectivement la somme de (m1 x), (m2 y), (m3 z) et le nombre d'atomes de carbones dans Z dans la formule (II) est comprise entre 15 et 60; p a une valeur comprise entre 0 et 100; q a une valeur comprise entre 0 et 100; la somme de p et q est supérieure à zéro; Z désigne hydrogène ou un reste linéaire ou ramifié aliphatique ayant entre 1 et 13 atomes de carbone, le reste R-O-[(Cm1H2m1O)x-(Cm2H2m2O)y-(Cm3H2m3O)z]co- dans la formule (I) ou le reste -[(Cm1H2m1O)x-(Cm2H2m2O)y-(Cm3H2m3O)z]co-Z dans la formule (II) présente au total entre 2 et 12 ramifications et entre 0,1 et 0,3 ramifications par atome de C.
