4 .-- from at least one emulsifier, or a mixture emulating nani a,

5. 0 to 6 parts by weight, the better

1 to 2 parts by weight

of a chemical compound that acts as a buffer material or regulator of the pH value, as well as, possibly,.

; 6. from water.

According to the invention the solvent or the solvent mixture consist of at least

3.1 a water-soluble chemical-organic solvent containing hydroxyl groups and / or ether groups, and in 3.2 a water-insoluble organic solvent or solvent mixture,

and, furthermore, the concentrate, respectively the medium, contains a high part by weight of the emulsifier 0 of the non-ionogenic emulsifying mixture.

A concentrate of a wood preservation medium and a wood preservation medium according to the concept of the patent application are disclosed in the unpublished Applicant's patent application P 30.04319 * 7. Such means for the preservation of wood present for? the inconvenient, due to the use of non-ionogenic insecticides and fungicides, which can form, for example, turbid emulsions, or which not always? a deposition of active substances is avoidable and therefore the risk of a partial loss of active substances or a reduction of the same.

With the present invention, which produces the wood preservation medium ready for processing by adding water, these inconveniences should be drunk, avoided and clear solutions ready for processing, preferably as pseudo-solutions, obtained. optically clear emulsions or myoroemulsions, immezz? cos? prepared, therefore having to present an active activity ._

According to the invention it has been established that they are up to par. d? these purposes and tasks a concentrate of a means for the preservation of wood and a means of protecting wood and wooden objects composed of.,
