Preservative compositions based on iodopropynyl- and formaldehyde donor compounds

摘要

The present invention relates to compositions having broad effectiveness against bacteria and fungi, which includes (a) an iodopropynylbutyl compound selected from iodopropynylbutyl esters, ethers, acetals, carbamates and carbonates and (b) one or more O-formals formed by the reaction of a monovalent or polyvalent C1-C10-alkyl, -aryl or -aralkyl alcohol or of a glycol or glycol ether and a formaldehyde-supplying compound. The compositions are also stable and effective in the form of liquid concentrates. The present invention also relates to the use of such compositions in industrial products and to industrial products which comprise these compositions.
