摘要： An evaporation inhibitor, having particular use with spray mixtures of agricultural chemicals applied by the low-volume method, in the form of a paraffin-containing aqueous dispersion or a self-emulsifying solution in an organic solvent, and having the following composition:______________________________________ from 15 to 40% by weight of paraffin waxes or a wax mixture containing paraffin waxes having a dropping point of from 35 to 80.degree. C., from 4 to 20% by weight of nonionic and/or anionic emulsifiers, from 35 to 81% by weight of water and/or an organic solvent which is one or more of a hydrocarbon, an ester and a ketone, which have boiling points of from 70 to 280.degree. C., and from 0 to 5.5% by weight of other auxiliaries. ______________________________________

摘要： Substantially water-insoluble silicic acid esters corresponding to the following general formula ##STR1## are used to foam inhibitors in foaming systems. In the above formula, X and Y represent the group --OR or a methyl group, R represents a polypropylene glycol ether group and, optionally, a polyethylene glycol ether group which may be substituted by alkoxyl, amino-alkyl, acyl, acylamino, dialkoxyl and oxyaminoalkyl groups containing from 4 to 24 carbon atoms. The total number of glycol ether groups amounts to between 1 and 100, the number of polypropylene glycol ether groups preferably being at least equal to or larger than the number of ethylene glycol ether groups.
