Abstract

The invention relates to silicic acid ester mixtures containing silicic acid esters of formulae (I) and (II), all ‘R’s being selected, independently of each other, from the following group: H, the straight-chained or branched, saturated or unsaturated, substituted or unsubstituted C1–6-hydrocarbon radicals and fragrance alcohol radicals and biocide alcohol radicals, m taking on values of 1 to 20 and n taking on values from 2 to 100. These esters of oligosilicic acid with fragrance alcohols or biocide alcohols are characterised by a good hydrolysis stability and can also be used in aqueous media or in processes for producing granulates without undergoing excessive losses of activity
