Silicic acid ester mixtures

Silicic acid ester mixtures corresponding to formulae I and II, characterized in that some of the substituents R and preferably at least 5 mol-% of the substituents R are selected from the group consisting of methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl and tert.butyl.

The use of silicic acid ester mixtures containing silicic acid esters corresponding to the following formulae:

• 16
• in which all the R's independently of one another are selected from the group consisting of H, linear or branched, saturated or unsaturated, substituted or unsubstituted C1-6 hydrocarbon radicals and the perfume alcohols and biocide alcohols and m assumes a value of 1 to 20 and n a value of 2 to 100,
• as a perfume in liquid or solid detergent and cleaning compositions.
